Changes with Apache 2.0.15-dev

*) Enhance rotatelogs so that a UTC offset can be specified, and

the logfile name can be formatted using strftime(3). (Brought

forward from 1.3.) [Ken Coar]

*) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling

DuplicateHandle on an IOCompletionPort (a practice which

MS "discourages"). The new model does not rely on associating

the completion port with the listening sockets, thus the

completion port can be completely managed within the child

process. A dedicated thread accepts connections off the network,

then calls PostQueuedCompletionStatus() to wake up worker

threads blocked on the completion port.

[Bill Stoddard]

*) Bring forward the --suexec-umask option which allows the

builder to preset the umask for suexec processes. [Ken Coar]

*) Add a -V flag to suexec, which causes it to display the

compile-time settings with which it was built. (Only

usable by root or the AP_HTTPD_USER username.) [Ken Coar]

*) Mod_include should always unset the content-length if the file is

going to be passed through send_parsed_content. There is no to

determine if the content will change before actually scanning the

entire content. It is far safer to just remove the C-L as long

as we are scanning it. [Ryan Bloom]

Changes with Apache 2.0.14

*) Fix content-length computation. We ONLY compute a content-length if

We are not in a 1.1 request and we cannot chunk, and this is a keepalive

or we already have all the data. [Ryan Bloom]

*) Report unbounded containers in the config file. Previously, a typo

in the </container> directive could result in the rest of the config

file being silently ignored, with undesired defaults used.

[Jeff Trawick]

*) Make the old_write filter use the ap_f* functions for the buffering.

[Ryan Bloom]

*) Move more code from the http module into the core server. This

is core code, basically the default handler, the default input

and output filters, and all of the core configuration directives.

All of this code is required in order for the server to work, with or

without HTTP. The server is closer to working without the HTTP

module, although there is still more to do. [Ryan Bloom]

*) Fix a number of SGI compile warnings throughout the server. Fix some

bad parameters to apr_bucket_read(). Fix a bad statement in

ap_method_in_list(). For the mod_rewrite cache use apr_time_t

consistently; we were mixing apr_time_t and time_t in invalid ways

before. In load_file(), call apr_dso_error() instead of

apr_strerror() so that we get a more specific string on some platforms.

PR #6980 [Jeff Trawick]

*) Allow modules to query the MPM about it's execution profile. This

query API can and should be extended in the future, but for now,

max_daemons, and threading or forking is a very good start.

[Jon Travis <jtravis@covalent.net>]

*) Modify mod_include to send blocks of data no larger than 9k.

Without this, mod_include will wait until the whole file is parsed,

or the first tag is found to send any data to the client.

[Paul J. Reder <rederpj@raleigh.ibm.com>]

*) Fix mod_info, so that <Directory> and <Location> directives are

not displayed twice when displaying the current configuration.

[Ryan Morgan <rmorgan@covalent.net>]

*) Add config directives to override DEFAULT_ERROR_MSG and

DEFAULT_TIME_FORMAT. This was sent in as PR 6193.

[Dan Rench <drench@xnet.com>]

*) Get mod_info building and loading on Win32. [William Rowe]

*) Begin to move protocol independant functions out of mod_http. The goal

is to have only functions that are HTTP specific in the http directory.

[Ryan Bloom]

Changes with Apache 2.0.13

*) Don't assume that there will always be multiple calls to the byterange

filter. It is possible that we will need to do byteranges with only

one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]

*) Move the error_bucket definition from the http module to the

core server. Every protocol will need this ability, not just

HTTP. [Ryan Bloom]

Changes with Apache 2.0.12

*) Modify mod_file_cache to save pre-formatted strings for

content-length and last-modified headers for performance.

[Mike Abbot <mja@trudge.engr.sgi.com>]

*) Namespace protect IOBUFSIZ since it is exposed in the API.

[Jon Travis <jtravis@covalent.net>]

*) Use "Basic" authentication instead of "basic" in ab, as the spec

says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]

*) Fix a seg fault in mod_userdir.c. We used to use the pw structure

without ever filling it out. This fixes PR 7271.

[Taketo Kabe <kabe@sra-tohoku.co.jp> and

Cliff Woolley <cliffwoolley@yahoo.com>]

*) Add a couple of GCC attribute tags to printf style functions.

[Jon Travis <jtravis@covalent.net>]

*) Add the correct language tag for interoperation with the Taiwanese

versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142

*) Migrate the perchild MPM to use the new apr signal child, and

APR thread functions. [Ryan Bloom]

*) Close one copy of the CGI's stdout before creating the new process.

The CGI will still have stdout, because we have already dup'ed it.

This keeps Apache from waiting forever to send the results of a CGI

process that has forked a long-lived child process.

[Taketo Kabe <kabe@sra-tohoku.co.jp>]

*) Remove the rest of the pthreads functions from the threaded MPM.

This requires the APR support for a signal thread that was just

added. [Ryan Bloom]

*) Make mod_dir use a fixup for sending a redirect to the browser.

Before this, we were using a handler, which doesn't make much

sense, because the handler wasn't generating any data, it would

either return a redirect error code, or DECLINED. This fits the

current hooks better. [Ryan Morgan <rmorgan@covalent.net>]

*) Make the threaded MPM use APR threads instead of pthreads.

[Ryan Bloom]

*) Get mod_tls to the point where it actually appears to work in all cases.

[Ben Laurie]

*) implement --enable-modules and --enable-mods-shared for "all" and

"most". [Greg Stein]

*) Move the threaded MPM to use APR locks instead of pthread locks.

[Ryan Bloom]

*) Rename mpmt_pthread to threaded. This is more in line with the

fact that mpmt_pthread shouldn't be using pthreads directly, and

it is a smaller name that doesn't tie into anything.

[Ryan Bloom]

*) Rename the module structures so that the exported symbol matches

the file name, and it is easier to automate the installation

process (generating LoadModule directives from the module filenames).

[Martin Kraemer]

*) Remove the coalesce filter. With the ap_f* functions, this filter

is no longer needed. [Ryan Bloom]

Changes with Apache 2.0.11

*) Remove the dexter MPM. Perchild is the same basic idea, but it has the

added feature of allowing a uid/gid per child process. If no

uid/gid is specified, then Perchild behaves exactly like dexter.

[Ryan Bloom]

*) Get perchild building again. [Ryan Bloom]

*) Don't disable threads just because we are using the prefork MPM.

If somebody wants to compile without threads, they must now add

--disable-threads to the configure command line. [Ryan Bloom]

*) Begin to move the calls to update_child_status into common code, so

that each individual MPM does not need to update the scoreboard itself.

[Ryan Bloom]

*) Allow mod_tls to compile under Unix boxes where openssl has been

installed to the system include files.

[Gomez Henri <new-httpd@slib.fr>]

*) Cleanup the mod_tls configure process. This should remove any need

to hand-edit any files. We require OpenSSL 0.9.6 or later, but

configure doesn't check that yet. [Ryan Bloom]

*) Add a very early prototype of SSL support (in mod_tls.c). It is

vital that you read modules/tls/README before attempting to build

it. [Ben Laurie]

*) Fix a potential seg fault on all platforms. David Reid fixed this

on BEOS, but the problem could happen anywhere, so we don't want

to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]

*) Add new LogFormat directive, %D, to log time it takes to serve a

request in microseconds. [Bill Stoddard]

*) Change AddInputFilter and AddOutputFilter to SetInputFilter and

SetOutputFilter. This corresponds nicely with the other Set

directives, which operate on containers while the Add* directives

tend to work directly on extensions. [Ryan Bloom]

*) Cleanup the header handling a bit. This uses the apr_brigade_*

functions for the buffering so that we don't need to compute

the length of the headers before we actually create the header

buffer. [Ryan Bloom]

*) Allow filters to buffer data using the ap_f* functions. These have

become macros that resolve directly to apr_brigade_*.

[Ryan Bloom]

*) Get the Unix MPM's to do a graceful restart again. If we are going

to register a cleanup with ap_cleanup_scoreboard, then we have to

kill the cleanup with the same function, and that function can't be

static. [Ryan Bloom]

*) Install all required header files. Without these, it was not

possible to compile some modules outside of the server.

[Ryan Bloom]

*) Fix the AliasMatch directive in Apache 2.0. When we brought a patch

forward from 1.3 to 2.0, we missed a single line, which broke regex

aliases. [Ryan Bloom]

*) We have a poor abstraction in the protocol. This is a temporary

hack to fix the bug, but it will need to be fixed for real. If

we find an error while sending out a custom error response, we back

up to the first non-OK request and send the data. Then, when we send

the EOS from finalize_request_protocol, we go to the last request,

to ensure that we aren't sending an EOS to a request that has already

received one. Because the data is sent on a different request than

the EOS, the error text never gets sent down the filter stack. This

fixes the problem by finding the last request, and sending the data

with that request. [Ryan Bloom]

*) Make the server status page show the correct restart time, and

thus the proper uptime. [Ryan Bloom]

*) Move the CGI creation logic from mod_include to mod_cgi(d). This

should reduce the amount of duplicate code that is required to

create CGI processes.

[Paul J. Reder <rederpj@raleigh.ibm.com>]

*) ap_new_connection() closes the socket and returns NULL if a socket

call fails. Usually this is due to a connection which has been

reset. [Jeff Trawick]

*) Move the Apache version information out of httpd.h and into release.h.

This is in preparation for the first tag with the new tag and release

system. [Ryan Bloom]

*) Begin restructuring scoreboard code to enable adding back in

the ability to use IPC other than shared memory.

Get mod_status working on Windows again. [Bill Stoddard]

*) Make mod_status work with 2.0. This will work for prefork,

mpmt_pthread, and dexter. [Ryan Bloom]

*) Correct a typo in httpd.conf.

[Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154

*) Really fix mod_rewrite map lookups this time. [Tony Finch]

*) Get the correct IP address if ServerName isn't set and we can't

find a fully-qualified domain name at startup.

PR#7170 [Danek Duvall <dduvall@eng.sun.com>]

*) Make mod_cgid work with SuExec. [Ryan Bloom]

*) Adopt apr user/group name features for mod_rewrite. Eliminates some

'extra' stat's for user/group since they should never occur, and now

resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS

volumes. [William Rowe]

*) Adopt apr features to simplify mod_includes. This changes the

behavior of the USER_NAME variable, unknown uid's are now reported

as USER_NAME="<unknown>" rather than the old user#000 result.

WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]

*) Adopt apr features for simplifing mod_userdir, and accept the new

Win32/OS2 exceptions without hiccuping. [William Rowe]

*) Replace configure --with-optim option by using and saving the

environment variable OPTIM instead. This is needed because configure

options do not support multiple flags separated by spaces.

[Roy Fielding]

*) Fix some byterange handling. If we get a byte range that looks like

"-999999" where that is past the end of the file, we should return

a PARTIAL CONTENT status code, and return the whole file as one big

byterange. This matches the 1.3 handling now. [Ryan Bloom]

*) Make the error bucket a real meta-data bucket. This means that the

bucket length is 0, and a read returns NULL data. If one of these

buckets is passed down after the headers are sent, this data will

just be ignored. [Greg Stein]

*) The prefork MPM wasn't killing child processes correctly if a restart

signal was received while the process was serving a request. The child

process would become the equivalent of a second parent process. If

we break out of the accept loop, then we need to do die after cleaning

up after ourselves. [Ryan Bloom]

*) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful

restarts. [Ryan Bloom]

*) Modify the apr_stat/lstat/getfileinfo calls within apache to use

the most optimal APR_FINFO_wanted bits. This spares Win32 from

performing very expensive owner, group and permission lookups

and allows the server to function until these apr_finfo_t fields

are implemented under Win32. [William Rowe]

*) Support for typedsafe optional functions - that is functions exported by

optional modules, which, therefore, may or may not be present, depending

on configuration. See the experimental modules mod_optional_fn_{ex,im}port

for sample code. [Ben Laurie]

*) filters can now report an HTTP error to the server. This is done

by sending a brigade where the first bucket is an error_bucket.

This bucket is a simple bucket that stores an HTTP error and

a string. Currently the string is not used, but it may be needed

to output an error log. The http_header_filter will find this

bucket, and output the error text, and then return

AP_FILTER_ERROR, which informs the server that the error web page

has already been sent. [Ryan Bloom]

*) If we get an error, then we should remove all filters except for

those critical to serving a web page. This fixes a bug, where

error pages were going through the byterange filter, even though

that made no sense. [Ryan Bloom]

*) Relax the syntax checking of Host: headers in order to support

iDNS. PR#6635 [Tony Finch]

*) Cleanup the byterange filter to use the apr_brigade_partition

and apr_bucket_copy functions. This removes a lot of very messy

code, and hopefully makes this filter more stable.

[Ryan Bloom]

*) Remove AddModule and ClearModuleList directives. Both of these

directives were used to ensure that modules could be enabled

in the correct order. That requirement is now gone, because

we use hooks to ensure that modules are in the correct order.

[Ryan Bloom]

*) When SuExec is specified, we need to add it to the list of

targets to be built. If we don't, then any changes to the

configuration won't affect SuExec, unless 'make suexec' is

specifically run. [Ryan Bloom]

*) Cleaned out open_file from mod_file_cache, as apr now accepts

the APR_XTHREAD argument to open a file for consumption by

parallel threads on win32. [William Rowe]

*) Correct a bug in determining when we follow symlinks. The code

expected a stat -1 result, not an apr_status_t positive error.

Also check if the APR_FINFO_USER fields are valid before we

follow the link. [William Rowe]

*) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to

mpm_common.c. These functions are only valid on some platforms,

so they should not be in the main-line code. [Ryan Bloom]

*) Remove ap_chdir_file(). This function is not thread-safe,

and nobody is currently using it. [Ryan Bloom]

*) Do not try to run make depend if there are no .c files in the

current directory, doing so makes `make depend` fail.

[Ryan Bloom]

*) Update highperformance.conf to work with either prefork or

pthreads mpms. [Greg Ames]

*) Stop checking to see if this is a pipelined request if we know

for a fact that it isn't. Basically, if r->connection->keepalive == 0.

This keeps us from making an extra read call when serving a 1.0

request. [Ryan Bloom and Greg Stein]

*) Fix the handling of variable expansion look-ahead in mod_rewrite,

i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of

more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]

*) Fix the RFC number mentioned when complaining about a missing

Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]

*) Fix an endless loop in ab which occurred when ab was posting

and the server dropped the connection unexpectedly.

[Jeff Trawick]

*) Fix a segfault while handling request bodies in ap_http_filter().

This problem has been seen with mod_dav usage as well as with

requests where the body was just being discarded. [Jeff Trawick]

*) Some adjustment on the handling and automatic setting (via

hints.m4) of various compilation flags (eg: CFLAGS). Also,

add the capability to specify flags (NOTEST_CFLAGS and

NOTEST_LDFLAGS) which are used to compile Apache, but

not used during the configuration process. Useful for

flags like "-Werror". [Jim Jagielski]

*) Stop using environment variables to force debug mode or

no detach. We now use the -D command line argument to

specify the correct mode. -DONE_PROCESS and -DNO_DETACH.

[Greg Stein, Ryan Bloom]

*) Change handlers to use hooks. [Ben Laurie]

*) Stop returning copies of filenames from both apr_file_t and

apr_dir_t. We pstrdup the filenames that we store in the

actual structures, so we don't need to pstrdup the strings again.

[Ryan Bloom]

*) mod_cgi: Fix some problems where the wrong error value was being

traced. [Jeff Trawick]

*) EBCDIC: Fix some missing ASCII conversion on some protocol data.

[Jeff Trawick]

*) Add generic hooks. [Ben Laurie]

*) Use a real pool to dup the error log descriptor. [Ryan Bloom]

*) Fix a segfault caused by mod_ext_filter when the external filter

program does not exist. [Jeff Trawick]

*) Fix an output truncation error when on an HTTP >= 1.0 request an

object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE

was served through mod_charset_lite (or anything else that would

create a transient bucket in this size range). ap_bucket_make_heap()

silently failed (fixed), transient_setaside() discovered it, but

ap_save_brigade() ignored it (fixed). [Jeff Trawick]

*) Ignore \r\n or \n when using PEEK mode for input filters. The problem

is that some browsers send extra lines at the end of POST requests, and

we don't want to delay sending data back to the user just because the

browser isn't well behaved. [Ryan Bloom]

*) Get SuEXEC working again. We can't send absolute paths to suExec

because it refuses to execute those programs. SuEXEC also wasn't

always recognizing configuration changes made using the autoconf

setup. [Ryan Bloom]

*) Allow the buildconf process to find the config.m4 files in the correct

order. Basically, we can now name config.m4 files as config\d\d.m4,

and we will sort them correctly when inserting them into the build

process. [Ryan Bloom]

*) Get mod_cgid to use apr calls for creating the actual CGI process.

This also allows mod_cgid to use ap_os_create_priviledged_process,

thus allowing for SuExec execution from mod_cgid. Currently, we do

not support everything that standard SuExec supports, but at least

it works minimally now. [Ryan Bloom]

*) Allow SuExec to be configured from the ./configure command line.

[Ryan Bloom]

*) Update some of the docs in README and INSTALL to reflect some of

the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]

*) If we get EAGAIN returned from the call to apr_sendfile, then we

need to call sendfile again. This gets us serving large files

such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]

*) Get the support programs building cleanly again.

[Cliff Woolley <cliffwoolley@yahoo.com>]

*) The Apache/Win32 Apache.exe and dll's now live in bin. The

current directory logic now backs up over bin/ to determine the

server root from the Apache.exe path.

*) Apache/Win32 now follows the standard conventions of mod_foo.so

loadable modules, dynamic libs are all named libfoo.dll, and the

makefile.win populates the include, lib and libexec directories.

*) Apache is now IPv6-capable. On systems where APR supports IPv6,

Apache gets IPv6 listening sockets by default. Additionally, the

Listen, NameVirtualHost, and <VirtualHost> directives support IPv6

numeric address strings (e.g., "Listen [fe80::1]:8080").

[Jeff Trawick]

*) Modify the install directory layout. Modules are now installed in

modules/. Shared libraries should be installed in libraries/, but

we don't have any of those on Unix yet. All install directories

are modifyable at configure time. [Ryan Bloom]

*) Install all header files in the same directory on Unix. [Ryan Bloom]

*) Get the functions in server/linked into the server, regardless of

which modules linked into the server. This uses the same hack

for Apache that we use for APR and apr-util to ensure all of the

necessary functions are linked. As a part of thise, the CHARSET_EBCDIC

was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make

the scripts a bit easier.

[Ryan Bloom]

*) Rework the RFC1413 handling to make it thread-safe, use a timeout

on the query, and remove IPv4 dependencies. [Jeff Trawick]

*) Get all of the auth modules to the point that they will install and

be loadable into the server. Our new build/install mechanism expects

that all modules will have a common name format. The auth modules

didn't use that format, so we didn't install them properly.

[Ryan Bloom]

*) API routines ap_pgethostbyname() and ap_pduphostent() are no longer

available. Use apr_getaddrinfo() instead. [Jeff Trawick]

*) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]

*) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts

after the end of the response. [Ryan Bloom]

*) Get byterange requests working with responses that do not have a

content-length. Because of the way byterange requests work, we have to

have all of the data before we can actually do the byterange, so we

can compute the content-length in the byterange filter.

[Ryan Bloom]

*) Get exe CGI's working again on Windows.

[Allan Edwards]

*) Get mod_cgid and mod_rewrite to work as DSOs by changing the way

they keep track of whether or not their post config hook has been

called before. Instead of a static variable (which is replaced when

the DSO is loaded a second time), use userdata in the process pool.

[Jeff Trawick]

Changes with Apache 2.0a9

*) Win32 now requires perl to complete the final install step for users

to build + install on Win32. Makefile.win now rewrites @@ServerRoot@

and installs the conf, htdocs and htdocs/manual directories.

[William Rowe]

*) Make mod_include use a hash table to associate directive tags with

functions. This allows modules to implement their own SSI tags easily.

The idea is simple enough, a module can insert it's own tag and function

combination into a hash table provided by mod_include. While mod_include

parses an SSI file, when it encounters a tag in the file, it does a

hash lookup to find the function that implements that tag, and passes

all of the relevant data to the function. That function is then

responsible for processing the tag and handing the remaining data back

to mod_include for further processing.

[Paul J. Reder <rederpj@raleigh.ibm.com>]

*) Get rid of ap_new_apr_connection(). ap_new_connection() now has

fewer parameters: the local and remote socket addresses were removed

from the parameter list because all required information is available

via the APR socket. [Jeff Trawick]

*) Distribution directory structure reorganized to reflect a

normal source distribution with external install targets.

[Roy Fielding]

*) The MPMs that need multiple segments of shared memory now create

two apr_shmem_t variables, one for each shared memory allocation.

the problem is that we can't determine how much memory will be required

for shared memory allocations once we try to allocate more than one

variable. The MM code automatically aligns the shared memory allocations,

so we end up needing to pad the amount of shared memory we want based

on how many variables will be allocated out of the shared memory segment.

It is just easier to create a second apr_shmem_t variable, and two

shmem memory blocks.

[Ryan Bloom]

*) Cleanup the export list a bit. This creates a single unified list of

functions exported by APR. The export list is generated at configure

time, and that list is then used to generate the exports.c file.

Because of the way the export list is generated, we only export those

functions that are valid on the platform we are building on.

[Ryan Bloom]

*) Enable logging the cookie with mod_log_config

[Sander van Zoest <sander@covalent.net>]

*) Fix a segfault in mod_info when it reaches the end of the configuration.

[Jeff Trawick]

*) Added lib/aputil/ as a placeholder for utility functions which are not

specific to the Apache HTTP Server (but do not make sense with APR).

The first utility is "apu_dbm": a set of functions to work with DBM

files. This first version can be compiled for SDBM or GDBM databases.

[Greg Stein]

*) Complete re-write of mod_include. This makes mod_include a filter that

uses buckets directly. This has now served the FAQ correctly.

[Paul Reder <rederpj@raleigh.ibm.com>]

*) Allow modules to specify the first filter in a sub_request when

making the sub_request. This keeps modules from having to change the

output_filter immediately after creating the sub-request, and therefore

skip the sub_req_output_filter. [Ryan Bloom]

*) Update ab to accept URLs with IPv6 literal address strings (in the

format described in RFC 2732), and to build Host header fields in

the same format. This allows IPv6 literal address strings to be

used with ab. This support has been tested against Apache 1.3 with

the KAME patch, but Apache 2.0 does not yet work with this format

of the Host header field. [Jeff Trawick]

*) Accomodate an out-of-space condition in the piped logs and the

rotatelogs.c code, and no longer churn log processes for this

condition. [Victor J. Orlikowski]

*) Add support for partial writes with apr_sendfile() to core_output_filter.

[Greg Ames]

Changes with Apache 2.0a8

*) Add a directive to mod_mime so that filters can be associated with

a given mime-type.

[Ryan Bloom]

*) Get multi-views working again. We were setting the path_info

field incorrectly if we couldn't find the specified file.

[Ryan Bloom]

*) Fix 304 processing. The core should never try to send the headers

down the filter stack. Always, just setup the table in the request

record, and let the header filter convert it to data that is ready

for the network.

[Ryan Bloom]

*) More fixes for the proxy. There are still bugs in the proxy code,

but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)

successfully.

[Ryan Bloom]

*) Fix params for apr_getaddrinfo() call in connect proxy handler.

[Chuck Murcko]

*) APR: Add new apr_getopt_long function to handle long options.

[B. W. Fitzpatrick <fitz@red-bean.com>]

*) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.

Add generic apr_create_socket(). Add apr_getaddrinfo() for doing

hostname resolution/address string parsing and building

apr_sockaddr_t. Add apr_get_sockaddr() for getting the address

of one of the apr_sockaddr_t structures for a socket. Change

apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]

*) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but

I have proxied pages with it, cleanup will commence soon.

[Ryan Bloom]

*) Make the proxy work with filters. This isn't perfect, because we

aren't dealing with the headers properly. [Ryan Bloom]

*) Do not send a content-length iff the C-L is 0 and this is a head

request. [Ryan Bloom]

*) Make cgi-bin work as a regular directory when using mod_vhost_alias

with no VirtualScriptAlias directives. PR#6829 [Tony Finch]

*) Remove BUFF from the PROXY connect handling. [Ryan Bloom]

*) Get the default_handler to stop trying to deal with HEAD requests.

The idea is to let the content-length filter compute the C-L before

we try to send the data. If we can get the C-L correctly, then we

should send it in the HEAD response.

[Ryan Bloom]

*) The Header filter can now determine if a body should be sent based

on r->header_only. The general idea of this is that if we delay

deciding to send the body, then we might be able to compute the

content-length correctly, which will help caching proxies to cache

our data better. Any handler that doesn't want to try to compute

the content-length can just send an EOS bucket without data and

everything will just work.

[Ryan Bloom]

*) Add the referer to the error log if one is available.

[Markus Gyger <mgyger@itr.ch>]

*) Mod_info.c has now been ported to Apache 2.0. As a part of this

change, the root of the configuration tree has been exposed to modules

as ap_conftree.

[Ryan Morgan <rmorgan@covalent.net>]

*) Get the core_output_filter to use the bucket interface directly.

This keeps us from calling the content-length filter multiple times

for a simple static request.

[Ryan Bloom]

*) We are sending the content-type correctly now.

[Ryan Bloom and Will Rowe]

*) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report

a bogus bytes-sent value when the only thing being sent was trailers

and writev() returned an error (or EAGAIN). [Jeff Trawick]

*) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the

hints file to determine which platforms define

SINGLE_LISTEN_UNSERIALIZED_ACCEPT.

[Ryan Bloom]

*) APR: add apr_get_home_directory() [Jeff Trawick]

*) Initial import of 1.3-current mod_proxy. [Chuck Murcko]

*) Not all platforms have INADDR_NONE defined by default. Apache

used to make this check and define INADDR_NONE if appropriate,

but APR needs the check too, and I suspect other applications will

as well. APR now defines APR_INADDR_NONE, which is always a valid

value on all platforms.

[Branko �ibej <brane@xbc.nu>]

*) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.

[Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]

*) Relax the syntax checking of Host: headers in order to support

iDNS. PR#6635 [Tony Finch]

*) When reading from file buckets we convert to an MMAP if it makes

sense. This also simplifies the default handler because the

default handler no longer needs to try to create MMAPs.

[Ryan Bloom]

*) BUFF has been removed from the main server. The BUFF code will remain

in the code until it has been purged from the proxy module as well.

[Ryan Bloom]

*) Byteranges have been completely re-written to be a filter. This

has been tested, and I believe it is working correctly, but it could

doesn't work for the Adobe Acrobat plug-in. The output almost matches

the output from 1.3, the only difference being that 1.3 includes

a content-length in the response, and this does not.

[Ryan Bloom]

*) APR read/write functions and bucket read functions now operate

on unsigned integers, instead of signed ones. It doesn't make

any sense to use signed ints, because we return the error codes,

so if we have an error we should report 0 bytes read or written.

[Ryan Bloom]

*) Always compute the content length, whether it is sent or not.

The reason for this, is that it allows us to correctly report

the bytes_sent when logging the request. This also simplifies

content-length filter a bit, and fixes the actual byte-reporing

code in mod_log_config.c

[Ryan Bloom]

*) Remove AP_END_OF_BRIGADE definition. This does not signify what

it says, because it was only used by EOS and FLUSH buckets. Since

neither of those are required at the end of a brigade, this was

really signifying FLUSH_THE_DATA, but that can be determined better

by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH

buckets now return a length of 0, which is actually the amount of data

read, so they make more sense.

[Ryan Bloom]

*) Allow the core_output_filter to save some data past the end of a

request. If we get an EOS bucket, we only send the data if it

makes sense to send it. This allows us to pipeline request

responses. As a part of this, we also need to allocate mmap

buckets out of the connection pool, not the request pool. This

allows the mmap to outlive the request.

[Ryan Bloom]

*) Make blocking and non-blocking bucket reads work correctly for

sockets and pipes. These are the only bucket types that should

have non-blocking reads, because the other bucket types should

ALWAYS be able to return something immediately.

[Ryan Bloom]

*) In the Apache/Win32 console window, accept Ctrl+C to stop the

server, but use Ctrl+Break to initiate a graceful restart

instead of duplicating behavior. [John Sterling]

*) Patch mod_autoindex to set the Last-Modified header based on

the directory's mtime, and add the ETag header. [William Rowe]

*) Merge the 1.3 patch to add support for logging query string in

such a way that "%m %U%q %H" is the same as "%r".

[Bill Stoddard]

*) Port three log methods from mod_log_config 1.3 to 2.0:

CLF compliant '-' byte count, method and protocol.

[Bill Stoddard]

*) Add a new LogFormat directive, %c, that will log connection

status at the end of the response as follows:

'X' - connection aborted before the response completed.

'+' - connection may be kept-alive by the server.

'-' - connection will be closed by the server.

[Bill Stoddard]

*) Expand APR for WinNT to fully accept and return utf-8 encoded

Unicode file names and paths for Win32, and tag the Content-Type

from mod_autoindex to reflect that charset if the the feature

macro APR_HAS_UNICODE_FS is true. [William Rowe]

*) Compute the content length (and add appropriate header field) for

the response when no content length is available and we can't use

chunked encoding. [Jeff Trawick]

*) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,

so that content input filters get dechunked data when using

the default handler. Also removed REQUEST_CHUNKED_PASS.

[Sascha Schumann]

*) Add mod_ext_filter as an experimental module. This module allows

the administrator to use external programs as filters. Currently,

only filtering of output is supported. [Jeff Trawick]

*) Most Apache functions work on EBCDIC machines again, as protocol

data is now translated (again). [Jeff Trawick]

*) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of

the EBCDIC support. They are noops on ASCII machines, so this

type of translation doesn't have to be surrounded by #ifdef

CHARSET_EBCDIC. [Jeff Trawick]

*) Fix mod_include. tag commands work again, and the server will

send the FAQ again. This also allows mod_include to set aside

buckets that include partial buckets.

[Ryan Bloom and David Reid]

*) Add suexec support back. [Manoj Kasichainula]

*) Lingering close now uses the socket directly instead of using

BUFF. This has been tested, but since all we can tell is that it

doesn't fail, this needs to be really hacked on.

[Ryan Bloom]

*) Allow filters to modify headers and have those headers be sent to

the client. The idea is that we have an http_header filter that

actually sends the headers to the network. This removes the need

for the BUFF to send headers.

[Ryan Bloom]

*) Charset translation: mod_charset_lite handles translation of

request bodies. Get rid of the xlate version of ap_md5_digest()

since we don't compute digests of filtered (e.g., translated)

response bodies this way anymore. (Note that we don't do it at

all at the present; somebody needs to write a filter to do so.)

[Jeff Trawick]

*) Input filters and ap_get_brigade() now have a input mode parameter

(blocking, non-blocking, peek) instead of a length parameter.

[hackathon]

*) Update the mime.types file to the registered media types as

of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,

Tony Finch]

*) Namespace protect some macros declared in ap_config.h

[Ryan Bloom]

*) Support HTTP header line folding with input filtering.

[Greg Ames]

*) Mod_include works again. This should still be re-written, but at

least now we can serve an SHTML page again.

[Ryan Bloom]

*) Begin to remove BUFF from the core. Currently, we keep a pointer

to both the BUFF and the socket in the conn_rec. Functions that

want to use the BUFF can, functions that want to use the socket,

can. They point to the same place.

[Ryan Bloom]

*) apr_psprintf doesn't understand %lld as a format. Make it %ld.

[Tomas "�gren" <stric@ing.umu.se>]

*) APR pipes on Unix and Win32 are now cleaned up automatically when the

associated pool goes away. (APR pipes on OS/2 were already had this

logic.) This resolvs a fatal file descriptor leak with CGIs.

[Jeff Trawick]

*) The final line of the config file was not being read if there was

no \n at the end of it. This was caused by apr_fgets returning

APR_EOF even though we had read valid data. This is solved by

making cfg_getline check the buff that was returned from apr_fgets.

If apr_fgets return APR_EOF, but there was data in the buf, then we

return the buf, otherwise we return NULL.

[Ryan Bloom]

*) Piped logs work again in the 2.0 series.

[Ryan Bloom]

*) Restore functionality broken by the mod_rewrite security fix:

rewrite map lookup keys and default values are now expanded

so that the lookup can depend on the requested URI etc.

PR #6671 [Tony Finch]

*) Tighten up the syntax checking of Host: headers to fix a

security bug in some mass virtual hosting configurations

that can allow a remote attacker to retrieve some files

on the system that should be inaccessible. [Tony Finch]

*) Add a pool bucket type. This bucket is used for data allocated out

of a pool. If the pool is cleaned before the bucket is destroyed, then

the data is converted to a heap bucket, allowing it to survive the

death of the pool.

[Ryan Bloom]

*) Add a flush bucket. This allows modules to signal that the filters

should all flush whatever data they currently have. There is no way

to actually force them to do this, so if a filter ignores this bucket,

that's life, but at least we can try with this.

[Ryan Bloom]

*) Add an output filter for sub-requests. This filter just strips the

EOS bucket so that we don't confuse the main request's core output

filter by sending multiple EOS buckets. This change also makes sub

requests start to send EOS buckets when they are finished.

[Ryan Bloom]

*) Make ap_bucket_(read|destroy|split|setaside) into macros. Also

makes ap_bucket_destroy a return void, which is okay because it

used to always return APR_SUCCESS, and nobody ever checked its

return value anyway.

[Cliff Woolley <cliffwoolley@yahoo.com>]

*) Remove the index into the bucket-type table from the buckets

structure. This has now been replaced with a pointer to the

bucket_type. Also add some macros to test the bucket-type.

[Ryan Bloom]

*) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols

for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)

and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.

All _VAR_ flavors changes to _DATA to be absolutely clear.

[William Rowe]

*) Add support for /, //, //servername and //server/sharename

parsing of <Directory> blocks under Win32 and OS2.

[Tim Costello, William Rowe, Brian Harvard]

*) Remove the function pointers from the ap_bucket type. They have been

replaced with a global table. Modules are allowed to register bucket

types and use then use those buckets.

[Ryan Bloom]

*) mod_cgid: In the handler, shut down the Unix socket (only for write)

once we finish writing the request body to the cgi child process;

otherwise, the client doesn't hit EOF on stdin. Small request bodies

worked without this change (for reasons I don't understand), but large

ones didn't. [Jeff Trawick]

*) Remove file bucket specific information from the ap_bucket type.

This has been moved to a file_bucket specific type that hangs off

the data pointer in the ap_bucket type.

[Ryan Bloom]

*) Input filtering now has a third argument. This is the amount of data

to read from lower filters. This argument can be -1, 0, or a positive

number. -1 means give me all the data you have, I'll deal with it and

let you know if I need more. 0 means give me one line and one line

only. A positive number means I want no more than this much data.

Currently, only 0 and a positive number are implemented. This allows

us to remove the remaining field from the conn_rec structure, which

has also been done.

[Ryan Bloom]

*) Big cleanup of the input filtering. The goal is that http_filter

understands two conditions, headers and body. It knows where it is

based on c->remaining. If c->remaining is 0, then we are in headers,

and http_filter returns a line at a time. If it is not 0, then we are

in body, and http_filter returns raw data, but only up to c->remaining

bytes. It can return less, but never more.

[Greg Ames, Ryan Bloom, Jeff Trawick]

*) mod_cgi: Write all of the request body to the child, not just what

the kernel would accept on the first write. [Jeff Trawick]

*) Back out the change that moved the brigade from the core_output_filters

ctx to the conn_rec. Since all requests over a given connection

go through the same core_output_filter, the ctx pointer has the

correct lifetime.

[Ryan Bloom]

*) Fix another bug in the send_the_file() read/write loop. A partial

send by apr_send would cause unsent data in the read buffer to

get clobbered. Complete making send_the_file handle partial

writes to the network.

[Bill Stoddard]

*) Fix a couple of type fixes to allow compilation on AIX again

[Victor J. Orlikowski <v.j.orlikowski@gte.net>]

*) Fix bug in send_the_file() which causes offset to be ignored

if there are no headers to send.

[Bill Stoddard]

*) Handle APR_ENOTIMPL returned from apr_sendfile in the core

filter. Useful for supporting Windows 9* with a binary

compiled on Windows NT.

[Bill Stoddard]

Changes with Apache 2.0a7

*) Reimplement core_output_filter to buffer/save bucket brigades

across multiple calls to the core_filter. The brigade will be

sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE

thresholds are hit or the EOS bucket is received.

[Bill Stoddard]

*) Create experimental filter (buffer_filter) that coalesces bytes

into one large buffer before invoking the next filter in the

chain. This filter is particularly useful with the current

implementation of mod_autoindex when it inserted above the

chunk_filter. mod_autoindex generates a lot of brigades that

containing buckets holding just a few bytes each. The

buffer_filter coalesces these buckets into a single large bucket.

[Bill Stoddard]

*) Add apr_sendfile() support into the core_output_filter.

[Bill Stoddard]

*) Add apr_sendv() support into the core_output_filter.

[Bill Stoddard]

*) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS

[Mike Abbott <mja@sgi.com>]

*) Remove ap_send_fb. This is no longer used in Apache, and it doesn't

make much sense, because Apache uses buckets instead of BUFFs now.

[Ryan Bloom]

*) send_the_file now falls back to a read/write loop on platforms that

do not have sendfile.

[Ryan Bloom and Brian Havard]

*) Install apachectl correctly, and substitute the proper values so

that it works again. [Ryan Bloom]

*) Better(??) handle platforms that lack sendfile().

[Jim Jagielski]

*) APR now has UUID generation/formatting/parsing support.

[Greg Stein]

*) Begin the http_filter. This is an input filter that understands

the absolute basic amount required to parse an HTTP Request. The

goal is to be able to split headers from request body before passing

the data back to the other filters.

[Ryan Bloom]

*) Bring forward from 1.3.13 the config directory implementation

[Jim Jagielski]

*) install apxs if it is created

[Ryan Bloom]

*) Added APR_IS_STATUS_condition test macros to eliminate canonical error

conversions. [William Rowe]

*) Now that we have ap_add_input_filter(), rename ap_add_filter() to

ap_add_output_filter(). [Jeff Trawick]

*) Multiple build and configuration fixes

Build process:

-add datadir and localstatedir substitutions

-fix layout name

-fix logfilename misspelling

-fix evaluation of installation dir variables and

-replace $foobar by $(foobar) to be usefull in the makefile

Cross compile:

-add rules for cross-compiling in rules.mk. Okay, rule to check for

$CC_FOR_BUILD is still missing

-use CHECK_TOOL instead of CHECK_PROG for ranlib

-add missing "AR=@AR@" to severaly Makefile.in's

-cache result for "struct rlimit"

-compile all helper programs with native and cross compiler

and use the native version to generate header file

["R�diger" Kuhlmann <Tadu@gmx.de>]

*) Prepare our autoconf setup for autoconf 2.14a and for cross-

compiling.

["R�diger" Kuhlmann <Tadu@gmx.de>]

*) Fix a bug where a client which only sends \n to delimit header

lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED

message. Start working on ebcdic co-existance with input

filtering.

[William Rowe, Greg Ames]

*) If mod_so is enabled in the server always create libexec, even

if there are no modules installed in this directory. This is a

requirement for APXS to work correctly.

[Ryan Bloom]

*) Connection oriented output filters are now stored in the

conn_rec instead of the request_rec. This allows us to add the

output filter in the pre-connection phase instead of the

post_read_request phase, which keeps us from trying to write an

error page before we have a filter to write to the network.

[Ryan Bloom, Jeff Trawick, and Greg Ames]

*) Cleaning up an mmap bucket no longer deletes the mmap. An

mmap can be used across multiple buckets (default_handler with

byte ranges, mod_file_cache, mod_mmap_static), so cleanup of

the mmap itself can't be associated with the bucket.

[Jeff Trawick]

*) Add .dll caching directive ISAPICacheFile to mod_isapi.

[William Rowe]

*) Radical surgery to improve mod_isapi support under Win32.

Includes a number of newer ServerSupportFunction calls, support

for ReadClient (in order to retrieve POSTs greater than 48KB),

and general bug fixes to more reliably load ISAPI .dll's and

prevent leaking handle resources. Note: There are still

discrepancies between IIS's and Apache's ServerVariables, and

async calls are still not supported. Additional warnings are

logged to facilitate debugging of unsupported ISAPI calls.

[William Rowe]

*) Add input filtering to Apache. The basic idea for the input

filters is the same as the ideas for output filters. The biggest

difference is that instead of calling ap_pass_brigade, ap_get_brigade

should be called, and the order of execution for the filter itself is

different. When writing an output filter, a brigade is passed in,

and filters operate directly on that brigade, when done, they call

ap_pass_brigade. Input filters are the exact opposite. Because input

is not a push operation, filters first call ap_get_brigade. When this

function returns, the input filter will be left with a valid brigade.

The input filter should then operate on the brigade, and return.

[Ryan Bloom]

*) Fix building on BSD/OS using its native make. The build system

falls back to the BSD .include directive on that host platform.

[Sascha Schumann]

*) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,

SHA1 and plaintext password encodings. Make feature tests a

bit more flexible. [William Rowe]

*) Charset translation: mod_charset_lite handles output content

translation in a filter. mod_charset_lite no longer ignores

subrequests. A bunch of cruft related to BUFF's support for

translating request and response bodies was removed.

[Jeff Trawick]

*) Move the addition of the CORE filter to the post_read_request

hook in http_core.c. This removes the need to add the filter in

multiple places and allows for an SSL module to be added much

simpler. [Ryan Bloom]

*) Fix a security problem that affects certain configurations of

mod_rewrite. If the result of a RewriteRule is a filename that

contains expansion specifiers, especially regexp backreferences

$0..$9 and %0..%9, then it may be possible for an attacker to

access any file on the web server. [Tony Finch]

*) Fix a bug where errors that are detected during early request parsing

don't produce visible HTTP error messages at the browser, because

the core_filter wasn't present. [Greg Ames]

*) Provide apr_socklen_t as a portability aid.

[Victor J. Orlikowski]

*) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)

as well as a comment arg to the add, adduser and update cmds.

update allows the user to clear or preserve pw/groups/comment.

Fixed a bug in dbmmanage that prevented the check option from

parsing a password followed by :group... text. Corrected the

seed calcualation for Win32 systems, and added -lsdbm support.

[William Rowe]

*) Configured mod_auth_dbm to compile with sdbmlib under Win32.

[William Rowe]

*) Avoid a segfault when parsing .htaccess files. An

uninitialized tree pointer was passed to ap_build_config().

[Jeff Trawick]

*) Change the way that inet_addr & inet_network are checked for

in APR's configure process to allow BeOS BONE to correctly

find them. With this change BeOS BONE now builds from source

with no problems. [David Reid]

*) Fix a bug in apr_create_process() for Unix. The NULL signifying

the end of the parameters to execve() was stored in the wrong

location, overlaying the storage beyond the newargs[] array and

also passing uninitialized storage to execve(), which would

sometimes fail with EFAULT. [Jeff Trawick]

*) Fix a bug parsing configuration file containers. With a sequence

like this in the config file

<IfModule mod_kilroy.c>

any stuff

</IfModule>

<IfModule mod_lovejoy.c>

(blank line)

any stuff

</IfModule>

the second container would be terminated at the blank line due to

sediment in the buffer from reading the prior </IfModule> and an

error message would be generated for the real </IfModule> for the

second container. Also due to this problem, any two characters

could be used for "</" in the close of a container.

[Jeff Trawick]

*) ap_add_filter prototype changed to remove the ctx pointer. The

pointer still remains in the filter structure, but it can not be

a part of the ap_add_filter prototype. The reason is that when

the core uses AddFilter to add a filter to the stack it doesn't

know how to allocate the ctx pointer, or even how much memory should

be allocated. The filters will have to be responsible for allocating

the ctx memory when they need it.

[Ryan Bloom]

*) Add an AddFilter directive. This directive takes a list of filters

that should be activated for the requested resource.

[Ryan Bloom]

*) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps

some other platforms). [Jeff Trawick]

*) Modify mod_include to be a filter. Currently, it has only been tested

on actual files, but it should work for CGI scripts too.

[Ryan Bloom]

*) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted

writes. apr_flush() for Unix: handle interrupted writes.

[Jeff Trawick]

*) NameVirtualHost can now take "*" as an argument instead of

an IP address. This allows you to create a purely name-based

virtual hosting server that does not have any IP addresses in

the configuration file and which ignores the local address

of any connections. PR #5595, PR #4455 [Tony Finch]

*) Fix some compile warnings in mod_mmap_static.c

[Mike Abbott <mja@sgi.com>]

*) Fix chunking problem with CGI scripts. The general problem was that

the CGI modules were adding an EOS bucket and then the core added an

EOS bucket. The chunking filter finalizes the chunked response when it

encounters an EOS bucket. Because two EOS buckets were sent, we

finalized the response twice. The fix is to make sure we only send one

EOS, by utilizing a flag in the request_rec.

[Ryan Bloom]

*) apr_put_os_file() now sets up the unget byte appropriately on Unix

and Win32. Previously, the first read from an apr_file_t set up via

apr_put_os_file() would return a '\0'. [Jeff Trawick]

*) Mod_cgid now creates a single element bucket brigade, with a pipe

bucket, instead of using BUFF's and ap_r*.

[Ryan Bloom]

*) APRVARS.in no longer overwrites the EXTRA_LIBS variable.

[Mike Abbott <mja@sgi.com>]

*) Remove ap_bopenf from buff code. This required modifying the file_cache

code to use APR file's directly instead of going through BUFFs.

[Ryan Bloom]

*) Fix compile break on some platforms for mod_mime_magic.c

[John K. Sterling <sterling@covalent.net>]

*) Fix merging of AddDefaultCharset directive.

PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]

*) Minor revamp of the rlimit sections of code. We now test

explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()

is now "available" even if the platform doesn't support

the rlimit family (it's just a noop though). [Jim Jagielski]

*) Migrate the pre-selection of which MPM to use for specific

platforms to hints.m4, which contains (or should contain)

all platform specific "hints". [Jim Jagielski]

*) Remove IOLs from Apache. With filtering, IOLs are no longer necessary

[Ryan Bloom]

*) Add tables with non-string/binary values to APR.

[Ken Coar]

*) Fix some bad calls to ap_log_rerror() in mod_rewrite.

[Jeff Trawick]

*) Update PCRE to version 3.2. [Ryan Bloom]

*) Change the way buckets' destroy functions are called so that

they can be more directly used when changing the type of a

bucket in place. [Tony Finch]

*) Add generic support for reference-counting the resources used by

buckets, and alter the HEAP and MMAP buckets to use it. Change

the way buckets are initialised to support changing the type of

buckets in place, and use it when setting aside TRANSIENT buckets.

Change the implementation of TRANSIENT buckets so that it can be

mostly shared with IMMORTAL buckets, which are now implemented.

[Tony Finch]

Changes with Apache 2.0a6

*) Add support to Apache and APR for dsos on OS/390. [Greg Ames]

*) Add a chunking filter to Apache. This brings us one step closer

to removing BUFF. [Ryan Bloom]

*) ap_add_filter now adds filters in a LIFO fashion. The first filter

added to the stack is the last filter to be called. [Ryan Bloom]

*) Apache 2.0 has been completely documented using Scandoc. The

docs can be generated by running 'make docs'. [Ryan Bloom]

*) Add filtered I/O to Apache. This is based on bucket brigades,

Currently the buckets still use BUFF under the covers, but that

should change quickly. The only currently written filter is the

core filter which just calls ap_bwrite. [The Apache Group]

*) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't

built with thread support. [Jeff Trawick]

*) Abort configuration if --with-layout was specified and there's

no layout definition file. [Ken Coar]

*) Add support for '--with-port=n' option to configure. [Ken Coar]

*) Add support for extension methods for the Allow response header

field, and an API routine for accessing r->allowed and the

list of extension methods in a unified manner. [Ken Coar]

*) mod_cern_meta: fix broken file reading loop in scan_meta_file().

[Rob Simonson <simo@us.ibm.com>]

*) Get xlate builds working again. The apr renaming in 2.0a5 broke

APACHE_XLATE builds. [Jeff Trawick]

*) A configuration file parsing problem was fixed. When the

configuration file started with an IfModule/IfDefine container,

only the last statement in the container would be retained.

[Jeff Trawick]

Changes with Apache 2.0a5

*) Perchild is serving pages after passing them to different child

processes. There are still a lot of bugs, but this does work. I

have made requests against the same installation of Apache, and had

different servers use different user IDs to serve the responses.

This change moves to using socketpair instead of an AF_UNIX socket.

[Ryan Bloom]

*) Perchild MPM still doesn't work perfectly, but it is serving pages.

It can't seem to pass between child processes yet, but I think we

are closer now than before. This moves us back to using Unix

Domain Sockets. [Ryan Bloom]

*) libapr functions and types renamed with apr_ prefix.

#include "apr_compat.h" for 1.3.x backwards compat

[Perl]

*) Fix problems with APR sockaddr handling on Win32. It didn't always

return the right information on the local socket address.

[Gregory Nicholls <gnicholls@level8.com>]

*) ap_recv() on Win32: Set bytes-read to 0 on error.

[Gregory Nicholls <gnicholls@level8.com>]

*) Add an option to not detach from the controlling terminal without

going into single process mode. This allows for much easier

debugging of the process startup code. [Ryan Bloom]

*) ab: don't use perror() to report the failure of an APR function.

[Jeff Trawick]

*) Make dexter, mpmt_pthread, and perchild MPMs not destroy the

scoreboard on graceful restarts.

[Ryan Bloom]

*) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.

An invalid ap_proc_t was passed to ap_create_process().

[Jeff Trawick]

*) Allow modules to register filters. Those filters are still

never called, but this is a step in the right direction.

[Ryan Bloom and Greg Stein]

*) Register the mod_cgid daemon process for cleanup so that it is

killed at termination if it does not die when the parent gets

SIGTERM. This change is to fix occasional problems where the

process stays around. Bugs in similar logic in mod_rewrite and

mod_include were also fixed. [Jeff Trawick]

*) Fix a bug in the time handling. Basically, we were imploding a time

in ap_parseHTTPdate, but it had bogus data in the exploded time format.

Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time

uses those two fields to adjust the time value. Because of the HTTP

spec, both of those values can be zero'ed out safely. This fixes

the bug correctly. [Ryan Bloom]

*) Fix a couple of place in the Windows code where the wrong error

code was being returned. [Gregory Nicholls <gnicholls@level8.com>]

*) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]

*) Added the APR_EOL_STR macro for platform dependent differences in

logfiles and other raw text (such as all APR files). Fixes logfiles

not terminated with cr/lf sequences in Win32. [William Rowe]

*) Move all strings functions in APR to src/lib/apr/strings and create

apr_strings.h for the prototypes. [Ryan Bloom]

*) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure

to repeat the syscall until we stop getting EINTR. I noticed a

related problem at termination (SIGTERM) on FreeBSD when using

fcntl(). Apache 1.3 had these new loops too. Also, make the flock()

implementation work properly with child init. Previously, ap_lock()

was essentially a no-op because all children were using different

locks and thus nobody ever blocked. [Jeff Trawick]

*) The htdocs/ tree has been moved out of the CVS source tree into

a separate area for easier development. This has NO EFFECT on

end-users or Apache installations. [Ken Coar]

*) Integrate the mod_dav module for WebDAV protocol handling. This

adds the dav and dav_fs modules, the SDBM library, and additional

XML handling utilities. [Greg Stein]

*) Clean out obsolete names (from httpd.h) for the HTTP Status Codes

[Greg Stein]

*) Update the lib/expat-lite/ library (bring forward changes from

the Apache 1.3 repository). [Greg Stein]

*) If sizeof(long long) == sizeof(long), then prefer long in APR

configure.in. [Dave Hill <ddhill@zk3.dec.com>]

*) Add ap_sendfile for Tru64 Unix. Also, add an error message for

machines where sendfile is detected, but nobody has written ap_sendfile.

[Dave Hill <ddhill@zk3.dec.com>]

*) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]

*) ab would start up more connections than needed, then quit when the

desired number were finished. Also fixed a logic error involving

ab keepalives. [Victor J. Orlikowski]

*) WinNT: Implement non-blocking pipes with timeouts to communicate

with CGIs. Apache 2.0a4 had non-blocking pipes but without

timeouts (i.e, if a timeout was specified, the pipe reverted to

a full blocking pipe). Now the behaviour is more in line with

Unix non-blocking pipes.

[Bill Stoddard]

*) WinNT: Implement accept socket reuse. Using mod_file_cache to

cache open file handles along with accept socket reuse enables

Apache 2.0 to serve non-keepalive requests for static files at

3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps

and Apache 2.0 will serve almost 1200 rps on my system).

[Bill Stoddard]

*) Merge mod_mmap_static function into mod_file_cache. mod_file_cache

supports two config directives, mmapfile (same behavious as

mod_mmap_static) and cachefile. Use the cachefile directive

to cache open file handles. This directive only works on systems

that have implemented the ap_sendfile API. cachefile works today

on Windows NT, but has not been tested on any flavors of Unix.

[Bill Stoddard]

*) Cleanup the configuration. With the last few changes the

configuration process automatically:

inherits information about how to build from APR. Allowing

APR to inform Apache that it should or should not use -ldl

Detects which mod_cgi should be used mod_cgi or mod_cgid,

based on the threading model

Apache calls APR's configure process before finishing it's

configuration processing, allowing for more information flow

between the two.

[Ryan Bloom]

*) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK

with non-zero argument makes the socket non-blocking. BeOS and

OS/2 already worked this way. [Jeff Trawick]

*) ap_close() now calls ap_flush() for buffered files, so write

operations work a whole lot better on buffered files.

[Jeff Trawick]

*) Fix error messages issued from MPMs which explain where to change

compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).

[Greg Ames]

*) ap_create_pipe() now leaves pipes in blocking state. (This helps

reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is

now the way that the blocking state of a pipe is manipulated.

ap_block_pipe() is gone. [Jeff Trawick]

*) Correct the problem where the only local host name that the IP stack

can discover are 'undotted' private names. If no fully qualified

domain name can be identified, the default ServerName will be set to

the machine's IP address string. A warning is always provided if the

ServerName not specified, but assumed. Solves PR6215 [William Rowe]

*) Repair problems with config file processing which caused segfault

at init when virtual hosts were defined and which caused ServerName to

be ignored when there was no valid DNS setup. [Jeff Trawick]

*) Removed pointless ap_is_aborted macro function. [Roy Fielding]

*) Add ap_sendfile implementation for AIX

[Victor J. Orlikowski]

*) Repair C++ compatibility in ap_config.h, apr_file_io.h,

apr_network_io.h, and apr_thread_proc.h.

[Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]

*) Bring the allocation and pool debugging code back into a working

state. This will need to be tested as so far it's only been used on

BeOS. [David Reid]

*) Change configuration command setup to be properly typesafe when in

maintainer mode. Note that this requires a compiler that can initialise

unions. [Ben Laurie]

*) Turn on buffering for config file reads. Part of this was to

repair buffered I/O support in Unix and implement buffered

ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]

*) Win32: Fix problem where UTC offset was not being set correctly

in the access log. Problem reported on news group by Jerry Baker.

[Bill Stoddard]

*) Fix segfault when reporting this type of syntax error:

"</container> without matching <container> section", where

container is VirtualHost or Directory or whatever.

[Jeff Trawick]

*) Prevent the source code for CGIs from being revealed when using

mod_vhost_alias and the CGI directory is under the document root

and a user makes a request like http://www.example.com//cgi-bin/cgi

as reported in <news:960999105.344321@ernani.logica.co.uk>

[Tony Finch]

*) Add support for the new Beos NetwOrking Environment (BONE)

[David Reid]

*) xlate: ap_xlate_conv_buffer() now tells the caller when the

final input char is incomplete; ap_bwrite_xlate() now handles

incomplete final input chars. [Jeff Trawick]

*) Yet another update to saferead/halfduplex stuff -- need to ensure

that a bhalfduplex call occurs before logging or else DNS and

such can delay the last packet of the response. [Dean Gaudet]

*) Some syscall reduction in APR on unix -- don't seek when setting

up an mmap; and don't fcntl() more than once per socket.

[Dean Gaudet]

*) When mod_cgid is started as root, the cgi daemon now switches

to the configured User/Group (like other httpd processes)

instead of continuing as root. [Jeff Trawick]

*) The prefork MPM now uses an APR lock for the accept() mutex.

It has not been getting a lock at all recently. httpd -V now

displays APR's selection of the lock mechanism instead of the

symbols previously respected by prefork. [Jeff Trawick]

*) Change the mmap() feature test to check only for existence.

The previous check required features not used by Apache.

[Greg Ames]

*) Fix a couple of bugs in mod_cgid: The cgi arguments were

sometimes mangled. The len parm to accept() was not

initialized, leading sometimes to an endless loop of failed

accept() calls on OS/390 and anywhere else that failed the call

if the len was negative. Use <sys/un.h> for struct sockaddr_un

instead of declaring it ourselves to fix a compilation problem

on Solaris. [Jeff Trawick]

*) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]

*) Fix zombie process problem with mod_cgi. [Jeff Trawick]

*) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]

*) Fix storage overlay when loading dsos. Symptom: Apache dies at

initialization if ALLOC_DEBUG is defined; no known symptom

otherwise. [Jeff Trawick]

*) Fix typo in configure script when checking for mod_so. bash

doesn't seem to have a problem but /bin/sh on Solaris does.

Symptom: "./configure: test: unknown operator =="

[Jeff Trawick]

*) Rebind the Win32 NT and 9x services control into the MPM.

All console, WinNT SCM and Win9x pseudo-service control code is

now wrapped within the WinNT MPM.

[William Rowe]

*) Make a copy of getenv("PATH") before storing for later use. Some

getenv() implementations use the same storage for successive calls.

CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]

*) Server Tokens work in 2.0 again. This also propogates the change

to allow just the product name in the server string using

PRODUCT_ONLY.

[Ryan Bloom]

Changes with Apache 2.0a4

*) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers

won't need to call it. [Greg Ames, Jeff Trawick]

*) Move pre_config hook call to between configuration read and config

tree walk. This allows all modules to implement pre_config hooks

and know that they will be called at an appropriate time.

[Ryan Bloom]

*) mod_cgi, mod_cgid: Make ScriptLog directive work again.

[Jeff Trawick]

*) Add pre-config hooks back to all modules.

[Ryan Bloom]

*) Fix a SIGSEGV in ap_md5digest(), which is used when you have

ContentDigest enabled and we can't/don't mmap the file.

[Jeff Trawick]

*) We now report the correct line number for syntax errors in config

files. [Ryan Bloom, Greg Stein, Jeff Trawick]

*) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-

related bugs, and changed shmem/locking to use apr API. Shared-mem

is currently disabled, however, because of problems with graceful

restarts. [Ronald Tschal�r]

*) Fix corruption of IFS variable in --with-module= handling.

Depending on the user's shell or customization thereof, there

would be errors generating ap_config_auto.h later in the configure

procedure. [Jeff Trawick]

*) mod_cgi: Restore logging of stderr from child process when ScriptLog

isn't used (as in 1.3), except that on Unix it is now logged via

ap_log_rerror() instead of by the child having STDERR_FILENO refer

to the error log. [Greg Ames, Jeff Trawick]

*) Add '-D' argument processing for run time configuration defines.

[William Rowe]

*) Organize http_main.c as independent code, such that no code or

global data is exported from it. WIN32 will dynamically link it

to the server core, so this will prevent mutual dependency.

[William Rowe]

*) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()

and APR_VAR_EXPORT to correctly resolve apr functions and globals.

[William Rowe]

*) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.

[William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]

*) Add mod_charset_lite for configuring character set translation.

[Jeff Trawick]

*) Add '-n' option to htpasswd to make it print its user:pw record

on stdout rather than having to frob a text file. [Ken Coar]

*) Fix saferead. Basically, we flush the output buffer if a read on the

input will block.

[Ryan Bloom]

*) APR: Add ap_xlate_get_sb() so that an app can find out whether or not

a conversion is single-byte only. [Jeff Trawick]

*) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that

the BeOS 5.0 documentation says that shutdown doesn't work yet.

[Roy Fielding]

*) Fix some minor errors where pid was being manipulated as an int

instead of the portable pid_t. [Roy Fielding]

*) Fix some error log prints that were printing the pointer to a

structure rather than the pid within the structure.

[Jeff Trawick, Roy Fielding]

*) ab: Fix a command-line processing bug; track bad headers in

err_response; support reading headers up to 2K.

[Ask Bjoern Hansen <ask@valueclick.com>]

*) Fix ap_resolve_env() so that it handles new function added in a prior

alpha (see "Added the capability to do ${ENVVAR} constructs in the

config file.") as well as the constructs used by mod_rewrite.

[Paul Reder <rederpj@raleigh.ibm.com>]

*) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]

*) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use

APR to perform translation, instead of accessing the hard-coded tables

in 1.3's ebcdic.c. [Jeff Trawick]

*) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.

[Jeff Trawick]

*) Add the ability to hook into the config file reading phase. Basically

if a directive is specified EXEC_ON_READ, then when that directive is

read from the config file, the assocaited function is executed. This

should only be used for those directives that must muck with HOW the

server INTERPRETS the config. This should not be used for directives

that re-order or replace items in the config tree. Those changes should

be made in the pre-config step.

[Ryan Bloom]

*) Add mod_example to the build system.

[Tony Finch]

*) APR: Add ap_xlate_conv_byte() to convert one char between single-

byte character sets. [Jeff Trawick]

*) Pick up various EBCDIC fixes from 1.3 (from Martin

Kraemer and Oliver Reh originally according to the change log).

[Jeff Trawick]

*) Fix a couple of problems in RFC1413 support (controlled by the

IdentityCheck directive). Apache did not build the request string

properly and more importantly Apache would loop forever if the

would-be ident server dropped the connection before sending a

properly terminated response. [Jeff Trawick]

*) apxs works in 2.0.

[Ryan Bloom]

*) Reliable piped logs work in 2.0.

[Ryan Bloom]

*) Introduce a hash table implementation into APR to be used for

replacing tables and other random data structures in Apache.

[Tony Finch]

*) Add some more error reporting to htpasswd in the case of problems

generating or accessing the temporary file. Also, pass in a

buffer if the implementation knows how to use it (i.e., if L_tmpnam

is defined). [Ken Coar]

*) Configure creates config.nice now containing your configure

options. Syntax: ./config.nice [--more-options]

[Sascha Schumann]

*) Fix various return code problems in APR on Win32. For most of

these, APR was returning APR_EEXIST instead of GetLastError()/

WSAGetLastError(). [Jeff Trawick]

*) Make piped logs work again in version 2.0

[Ryan Bloom]

*) Add VPATH support to UNIX build system of Apache and APR.

[Sascha Schumann]

*) Fix ap_tokenize_to_argv to respect the const arguments that are

passed to it.

[Ryan Bloom]

*) Fix mm's memcpy/memset macros, pointer arithmetic was broken.

Patch submitted to author.

[Sascha Schumann]

*) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require

/sbin in PATH on FreeBSD (all submitted to rse previously)

[Jeff Trawick]

*) Fix building Pthread-based MPMs on OpenBSD

[Sascha Schumann] PR#26

*) Fix ap_readdir() problem on systems where d_name[] field in

struct dirent is declared with only one byte. (This problem only

affected multithreaded builds.) This caused a segfault during

pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at

least). [Jeff Trawick]

*) Fix some make-portability problems on at least Tru64, Irix

and UnixWare.

[Sascha Schumann] PR#18, PR#39

*) Add ap_sigwait() to support old-style sigwait() on systems

like OS/390 and UnixWare.

[Sascha Schumann]

*) Add POSIX-thread flags for more platforms.

[Sascha Schumann]

*) Fix some minor bugs in ap_strerror(). Teach ap_strerror()

(on Unix, at least) to handle resolver errors. Fix a bug in

the definition of APR_ENOMEM so that ap_strerror() can spit

out the correct error message for it.

[Jeff Trawick]

Changes with Apache 2.0a3

*) mod_so reports ap_os_dso_error() if ap_dso_load() fails

[Doug MacEachern]

*) API: *HOOK* macros now have an AP_ prefix

[Doug MacEachern]

*) Win32: Eliminate redundant calls to initialize winsock.

[Tim Costello <timcostello@ozemail.com.au>]

*) Fix bugs initializing ungetchar for pipes.

[Chia-liang Kao <clkao@CirX.ORG>]

*) The ab program in the src/support directory is now portable using

APR.

[Ryan Bloom]

*) Support directory is being compiled when the server is built

[Ryan Bloom]

*) The configure option --with-program-name has been added to allow

developers to rename the executable at configure time. This also

changes the name of the config files to match the executable's name.

[Ryan Bloom]

*) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames

containing version numbers. [Martin Pool]

*) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on

Unix; access_log and error_log now created with these perms; non-

Unix is unaffected [Jeff Trawick]

*) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.

Replaced more magic numbers with MD5_DIGESTSIZE.

[William Rowe, Roy Fielding]

*) Win32: Get mod_auth_digest compiling and added to the Windows

build environment. Not tested and I'd be suprised if it

actually works. [Bill Stoddard]

*) Revamp the Win32 make environment. Makefiles have been removed and

Apache.dsw created to bring together all the pieces. Create new file

os/win32/BaseAddr.ref to define module base addresses (to prevent

dll relocation at start-up).

[William Rowe, Greg Marr, Tim Costello, Bill Stoddard]

*) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most

of the \015, \012, and \015\012 constants with macros.

[Greg Ames <gregames@us.ibm.com>]

*) Add ap_xlate_open() et al for translation of text between different

character sets. The initial implementation requires iconv().

[Jeff Trawick]

*) More FAQs and answers from comp.infosystems.www.servers.unix.

[Joshua Slive <slive@finance.commerce.ubc.ca>]

*) CGI output is being timed out now.

[Ryan Bloom]

*) Fix the problem with dieing quietly. dupfile now takes a pool which

is used by the new apr file. There is no reason to create a new file

with the same lifetime as the original file.

[Ryan Bloom]

*) Win32: Attempt to eliminate dll relocation at start-up by specifying

module base addresses. This will help shooting seg faults

in the field. [William Rowe <wrowe@lnd.com>]

*) Update Apache on Windows documentation. Add new document

describing how to compile Apache on Windows.

[William Rowe <wrowe@lnd.com>]

*) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take

microseconds instead of seconds. Some storage leaks and other

minor bugs in related code were fixed. [Jeff Trawick]

*) Win32: First cut at getting mod_isapi working under 2.0

[William Rowe <wrowe@lnd.com>]

*) First stab at getting mod_auth_digest working under 2.0

quick change summary:

- moved the random byte generation (ap_generate_random_bytes) into APR

- now uses ap_time_t

- compiles and runs on linux

- tested with amaya

[Brian Martin <bmartin@penguincomputing.com>]

*) Win32: Move the space stripping of physical service names

fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an

unresolved symbol. Add dependency checking to the

CreateService call to ensure TCPIP and AFP (winsock) is started

before Apache.

[William Rowe <wrowe@lnd.com>]

*) Win32: Add code to perform latebinding on functions that may

not exist on all levels of Windows where Apache runs. This

is needed to allow Apache to start-up on Win95/98. All calls

to non portable functions should be protected with

ap_oslevel checks to prevent runtime segfaults.

[William Rowe <wrowe@lnd.com>]

*) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]

*) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]

*) Win32: Get non-blocking CGI pipe reads working under Windows NT.

This addresses PR 1623. Still need to address timing out runaway

CGI scripts. [Bill Stoddard]

*) Win32: Make ap_stat Windows 95/98 friendly

[William Rowe <wrowe@lnd.com>]

*) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to

always fail. Need to initialise the dwOSVersionInfoSize member of the

OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx

always fails.

The patch also enhances ap_get_oslevel (and the associated enum) to

handle selected service packs for NT4, and adds recognition for

Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then

we can use ReadFileScatter and WriteFileGather in readwrite.c.

[Tim Costello <Tim.Costello@BTFinancialgroup.com>]

*) Get mod_rewrite building and running, and mod_status building for Win NT

[Allan Edwards <ake@raleigh.ibm.com>]

*) Patch to port mod_auth_db to the 2.0 api and also to support

Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and

2.7.7. It should work with version 1 as well but I haven't tested it.

[Brian Martin <bmartin@penguincomputing.com>]

*) Get APR DSO code working under Windows. Includes cross platform

fixes to mod_so.c.

[Tim.Costello@BTFinancialgroup.com]

*) Fix some of the Windows APR time functions.

[William Rowe]

*) FAQ changes related to tidying up historical documents on the web site.

[Joshua Slive <slive@finance.commerce.ubc.ca>]

*) Move Windows DSO code into APR.

[Bill Stoddard]

*) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).

Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw

at build time. At this point, the server will not compile on Windows because

of the recent DSO commits. Fixing those next.

[Bill Rowe & Bill Stoddard]

*) Added error checking for file I/O APR routines.

[Jon Travis <jtravis@covalent.net>]

*) APR: Don't use the values of resolver error codes for the

corresponding APR error codes. On Unix and Win32, return the

proper APR error code after a resolver error. [Jeff Trawick]

Changes with Apache 2.0a2

*) Renamed the executable back to httpd on all platforms other

than Win32

[Ryan Bloom]

*) Allow BeOS to survive restarts, log properly and a few

small things it had problems with due to the way it setup

users and groups. [David Reid]

*) Get mod_rewrite working with APR locks

[Paul Reder <rederpj@raleigh.ibm.com>]

*) Actually remove the sempahore when the lock cleanup routine

is called on BeOS. [David Reid]

*) Clear hook registrations between reads of the config file.

When DSOs are unloaded and re-loaded the old hook pointers may

no longer be valid. This fix eliminates potential segfaults.

[Allan Edwards <ake@raleigh.ibm.com>]

*) Fix a problem with Sigfunc not being defined or bypassed

if sigaction() wasn't found. [Jim Jagielski]

*) Fix the locking mechanism on BSD variants. They now use fcntl

locks. This allows the server to start and serve pages.

[Ryan Bloom]

*) First cut at getting the Win32 installer to work

[William Rowe <wrowe@lnd.com>]

*) Get htpasswd compiling under Windows

[William Rowe <wrowe@lnd.com>]

*) Change the log message for a bind() failure to show the

interface and port number. [Jeff Trawick]

*) Import the documentation from 1.3.12 and bring parts of it

up-to-date with respect to the changes that have occurred

in 2.0.

[Tony Finch]

*) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses

now logged correctly on BeOS.

[David Reid]

*) Create one makefile for all Win32 distributions (NT/2000/95/98).

Makefile.win includes the same user interface as the old

Makefile.nt

[William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]

*) Win32 exec now uses COMSPEC environment string for command

shell path resolution.

[William Rowe <wrowe@lnd.com>] PR#3715

*) Win32: ap_connect() was not returning correct error condition

PR5866

[Allen Prescott <allen@clanprescott.com>]

*) Win32: ap_open() was broken on Win9x because an NT-specific

flag was passed to CreateFile. ap_puts() added an unnecessary

'\n'.

[Jeff Trawick <trawick@us.ibm.com>]

*) Put in Korean and Norwegian index.html pages (2.0 and 1.3)

which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'

confusing ee/et name and made all extensions language/dialect

rather than country reflecting. Changed example files to

explicit reflect the ISO charset and added a few common

ones to the example config [dirkx]

*) Extend external module capability. To use this, you call

configure with --with-module=path/to/mod1,path/to/mod2,etc.

[Ryan Bloom]

*) Backported the various "default charset" fixes from 1.3.12,

including the AddDefaultCharset directive. [Jim Jagielski]

*) Added the capability to do ${ENVVAR} constructs in the

config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited

it does this on a line by line basis; i.e. if the envvar

expands to something with spaces you have to protect it

by adding quotes around it (Unless of course you expect it

to contains more than one argument. Alternatively you

can compile it on a per token basis; which is what people

usually expect by setting RESOLVE_ENV_PER_TOKEN. But this

hampers fancier hacks.

[Dirk-Willem van Gulik]

*) Changed the 'ErrorDocument' syntax in that it NO longer

supports the asymetric

ErrorDocument 301 "Some message

Note the opening " quote, without a closing quote. It now

has either the following syntaxes

ErrorDocument XXX /local/uri

ErrorDocument XXX http://valid/url

ErrorDocument XXX "Some Message"

The recognition heuristic is: if it has a space it

is a message. If it has no spaces and starts with a /

or is a valid URL then treat it that way. Otherwise it

is assumed to be a message.

This breaks backward compatibility but makes live a hell

of a lot easier for GUI's and config file parsers.

[Dirk-Willem van Gulik]

*) Changed 'CacheNegotiatedDocs' from its present/not-present

syntax into a 'on' or 'off' syntax. As it currently is the

only non nesting token which uses NO_ARGS and thus is an

absolute pain for any config interface automation. This

breaks backward compatibility. [Dirk-Willem van Gulik]

*) Add ability to add external modules to the build process. This is

done with --with-module=/path/to/module. Modules can only be added

as static modules at this point.

[Ryan Bloom]

Changes with Apache 2.0a1

*) Fix FreeBSD 3.3 core dump.

Basically, ap_initialize() needs to get called before

create_process(), since create_process() passes op_on structure

to semop() to get a lock, but op_on isn't initialized until

ap_initialize() calls setup_lock(). Here is a slight

rearrangement to main() which calls ap_initialize() earlier...

[Jeff Trawick <trawick@us.ibm.com>]

*) Enable Apache to use sendfile/TransmitFile API

[Bill Stoddard, David Reid, Paul Reder]

*) Re-Implement Win32 APR network I/O APIs and most of the file I/O

APIs.

[Bill Stoddard]

*) Make file I/O and network I/O writev/sendv APIs consistent.

Eliminate use of ap_iovec_t and use Posix struct iovec.

Use seperate variable on ap_writev to set the number of iovecs

passed in and number of bytes written.

[Bill Stoddard]

*) Adapt file iol to use APR functions. Replaced ap_open_file()

with ap_create_file_iol(). ap_create_file_iol() requires that

the file be opened prior to the call using ap_open().

[Bill Stoddard]

*) Port mod_include and mod_cgi to 2.0

[Paul Reder, Bill Stoddard]

*) ap_send{,v}, ap_recv, ap_sendfile API clarification --

bytes_read/bytes_written is always valid (never -1). Plus

some fixes to buff.c to correct problems introduced by the

errno => ap_status_t changes a while back. Plus a fix to

chunked encoding introduced right at the beginning of 2.0.

[Dean Gaudet]

*) Revamped UNIX build system to use autoconf and libtool.

[Manoj Kasichainula, Sascha Schumann]

*) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]

*) More rigorous checking of Host: headers to fix security problems

with mass name-based virtual hosting (whether using mod_rewrite

or mod_vhost_alias).

[Ben Hyde, Tony Finch]

*) Add back support for UseCanonicalName in <Directory> containers.

[Manoj Kasichainula]

*) Added APLOG_STARTUP log type. This allows us to write an error

message without any of the date and time information. As a part

of this change, I also removed all of the calls to fprintf(stderr

and replaced them with calls to ap_log_error using APLOG_STARTUP

writing to stderr is no longer portable, because we don't direct

stderr to the error log on all platforms.

[Ryan Bloom]

*) Convert error logging functions to take errno as an argument.

This makes our error logs more portable, because some Windows API's

don't set errno. This change allows us to still output a valid

message on all of our platforms.

[Ryan Bloom]

*) mod_mime_magic runs in 2.0-dev now.

[Paul Reder <rederpj@raleigh.ibm.com>]

*) sendfile has been added to APR.

[John Zedlewski <zedlwski@Princeton.EDU>]

*) buff.c has been converted to no longer use errno.

[Manoj Kasichainula]

*) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and

interface adaption to APR functions did it. [Martin Kraemer]

*) Support DSOs properly on 32-bit HP-UX 11.0

[Dilip Khandekar <dilip@cup.hp.com>]

*) Updated MM in APR source tree from version 1.0.8 to 1.0.11

[Ralf S. Engelschall]

*) Cleaned APR build environment integration and bootstrap APR

automatically for developers from src/Configure.

[Ralf S. Engelschall]

*) Fixed building of src/support/htpasswd.c

[Ralf S. Engelschall]

*) When generating the Location: header, mod_speling forgot

to escape the spelling-fixed uri. (Forw-Port from 1.3)

[Martin Kraemer]

*) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]

*) Change all pools to APR contexts. This is the first step to

incorporating APR into Apache. [Ryan Bloom]

*) Move "handler not found" warning message to below the check

for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]

PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807

*) Support line-continuation feature in config.option file and

allow the loading of multiple option sections at once via

``--with-option=<section1>,<section2>,...''

[Ralf S. Engelschall]

*) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]

Changes with Apache MPM

*) Use asynchronous AcceptEx() and a completion port to accept and

dispatch connections to threads in Windows NT/2000.

[Bill Stoddard]

*) Implement WINNT Win32 MPM from original Win32 code in http_main.c

[Bill Stoddard]

*) Implement the APACI --with-option facility

(per default used the config.option file).

[Ralf S. Engelschall]

*) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]

*) Start to implement module-defined hooks that are a) fast and b) typesafe.

Replace pre_connection module call with a register_hook call and

implement pre_connection as a hook. The intent is that these hooks will

be extended to allow Apache to be multi-protocol, and also to allow the

calling order to be specified on a per-hook/per-module basis.

[Ben Laurie]

*) Implement mpm_* methods as "modules". Each method gets its own

subdir in src/modules (eg: src/modules/prefork). Selection

of method uses Rule MPM_METHOD. [Jim Jagielski]

*) Port the hybrid server from the apache-apr repository as

mpm_mpmt_pthread. [Manoj Kasichainula]

*) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common

amongst the unix MPMs.

*) mpm_prefork: throw away all the alarm/timeout crud; and clean up the

signal handling for the new world order. [Dean Gaudet]

*) Crude ap_thread_mutex abstraction so that we get the pthread stuff out

of alloc.c for now. [Dean Gaudet]

*) Handle partial large writes correctly. [Ben Laurie]

*) Eliminate conn_rec's pointer to server. All it knows is the base server

based on IP/port. [Ben Laurie]

*) Port a bunch of modules to the new module structure.

["Michael H. Voase" <mvoase@midcoast.com.au>]

*) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]

*) Basic restructuring to introduce the MPM concept; includes various

changes to the module API... better described by

docs/initial_blurb.txt. [Dean Gaudet]

Changes with Apache pthreads

*) New buff option added: BO_TIMEOUT. It describes the timeout for

buff operations (generally over a network).

[Dean Gaudet, Ryan Bloom, Manoj Kasichainula]

*) Created http_accept abstraction. Added 4 new functions (not exported):

init_accept(), begin_accepting_requests(), get_request(),

stop_accepting_requests() [Bill Stoddard]

*) Fix to ap_rprintf call that allows mod_info to work properly.

[James Morris <jmorris@intercode.com.au>]

*) user and ap_auth_type fields were moved from connection_rec to

request_rec. [Ryan Bloom]

*) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't

needed in a threaded server.

*) Initial pthread implementation from from Dean's apache-nspr code.

[Bill Stoddard, Ryan Bloom]

Changes with Apache 1.3.9

*) Remove bogus error message when a redirect doesn't set Location.

Instead, use an empty string to avoid coredump if the error message

was supposed to include a location. [Roy Fielding]

*) Don't allow configure to include mod_auth_digest unless it is

explicitly requested, even if the user asked for all modules.

[Roy Fielding]

*) Translate module names to dll names for OS/2 so that they are no more

than 8 characters long and have an extension of "dll" instead of "so".

[Brian Havard]

*) Print out pointer to Rule DEV_RANDOM when truerand lib not found.

Fix test-compile check to check for randbyte instead of trand32.

Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c

and tweak to make Amaya happier. [Ronald Tschal�r]

*) Ensure that the installed expat include files are world readable,

just like the other header files. [Martin Kraemer]

*) Fixed generated AddModule adjustments in APACI's `configure' script

in order to allow (new) modules like mod_vhost_alias to be handled

correctly (which was touched by the adjustments for mod_alias).

[Ralf S. Engelschall]

*) For binary builds, add -R flag to apachectl to work around the lack of

an absolute path to the ./libexec directory where the libhttp.ep file

is needed for SHARED_CORE architectures. [Randy Terbush]

*) WIN32: Create the CGI script process as DETACHED. This may solve the

problem observed by some Win95/98 users where they get CGI script

output sent to the console. [Bill Stoddard]

*) Fix (re)naming in the uuencode/decode section. The ap/ap_

routines are now called ap_base64* and are 'plain' (i.e., no

pool access or anything clever). Inside util.c the routines acting

like pstrdup are called ap_pbase64encode() and ap_pbase64decode().

The oddly named ap_uuencode(), ap_uudecode() are kept around for

now but deprecated. [dirkx]

*) Clean up the base64 and SHA1 additions and make sure they are

represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp

files. [Roy Fielding]

*) WIN32: Migrate to InstallShield 5.5 and provide a bit more error

checking. Allow compiling on VS 6.0. [Randy Terbush]

*) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]

*) Use TestCompile to search for the truerand library (rather than blindly

assuming its existence). If it is not found, complain (but do not

exit - yet). [Martin Kraemer]

*) We forgot to add the new exported function names to

src/support/httpd.exp. [Bill Stoddard, Randy Terbush]

*) Add description of -T command-line option to usage().

[Ralf S. Engelschall]

*) For "some" platforms (notably, EBCDIC based ones), libos needs to be

searched only AFTER libap has been searched, because libap needs

some symbols from libos. [Martin Kraemer]

*) Fix conflict with original mod_digest related to the symbol of the

module dispatch list (which has to be unique for DSO and follow the

usual conventions for the installation procedure).

[Ralf S. Engelschall]

*) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)

for other platforms as well. [Martin Kraemer]

*) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG

types by AP_LONG and replace reference to renamed variable 'ubuf'

by 'buffer'. [Martin Kraemer]

Changes with Apache 1.3.8 [not released]

*) Flush the output buffer immediately after sending an error or redirect

response, since the result may be needed by the client to abort a

long data transfer or restart a series of pipelined requests.

[Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]

*) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.

[Ian Turner <iant@sequent.com>] PR#4735

*) Local struct mmap in http_core.c conflicted with system structure

name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735

*) Added updated mod_digest as modules/experimental/mod_auth_digest.

[Ronald Tschal�r <ronald@innovation.ch>]

*) Fix a memory leak where the module counts were getting messed

up across restarts. [David Harris <dharris@drh.net>]

*) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled

properly in mod_access.

["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770

*) RewriteLock/RewriteMap didn't work properly with virtual hosts.

[Dmitry Khrustalev <dima@bog.msu.su>] PR#3874

*) PORT: Support for compaq/tandem/com.

[Michael Ottati <michael.ottati@compaq.com>, dirkx]

*) Added SHA1 password encryption support to easy migration from

Netscape servers. See support/SHA1 for more information.

Caused the separation of ap_md5.c into md5, sha1 and a general

ap_checkpass.c with just a validate_passwd routine. Added a

couple of flags to support/htpasswd. Some reuse of the to64()

function; hence renamed to ap_to64().

[Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]

*) Change for EBCDIC platforms (TPF and BS2000) to correctly deal

with ASCII/EBCDIC conversions in "ident" query.

[David McCreedy <McCreedy@us.ibm.com>]

*) Get rid of redefinition warning on MAC_OS_X_SERVER platform.

Change "Power Macintosh" to Power* so if uname prints "Power Book"

we're still happy on Rhapsody platforms. [Wilfredo Sanchez]

*) Fix SIGSEGV on some systems because the Vary fix below included

a call to table_do with a variable argument list that was not

NULL terminated. Replaced with better implementation. [Roy Fielding]

Changes with Apache 1.3.7 [not released]

*) The "Vary" response header field is now sanitised right before

the header is sent back to the client. Multiple "Vary" fields

are combined, and duplicate tokens (e.g., "Vary: host, host" or

"Vary: host, negotiate, host, accept-language") are reduced to

single instances. This is a better solution than the force-no-vary

one (which is still valid for clients that can't cope with Vary

at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]

*) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]

*) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at

least on Linux and FreeBSD for now.

[Rasmus Lerdorf]

*) Win32: More apache -k restart work. Restarts are now honored

immediately and connections in the listen queue are -not- lost.

This is made possible by the use of the WSADuplicateSocket()

call. The listeners are opened in the parent, duplicated, then

the duplicates are passed to the child. The original listen sockets

are not closed by the parent across a restart, thus the listen queue

is preserved.

[Bill Stoddard <stoddard@raleigh.ibm.com>]

*) Fix handling of case when a client has sent "Expect: 100-continue"

and we are going to respond with an error, but get stuck waiting to

discard the body in the pointless hope of preserving the connection.

[Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806

*) Fix 'configure' to work correctly with SysV-based versions of

'tr' (consistent with Configure's use as well). [Jim Jagielski]

*) apxs: Add "-S var=val" option which allows for override of CFG_*

built-in values. Add "-e" option which works like -i but doesn't

install the DSO; useful for editing httpd.conf with apxs. Fix

editing code so that multiple invocations of apxs -a will not

create duplicate LoadModule/AddModule entries; apxs can now be

used to re- enable/disable a module. [Wilfredo Sanchez]

*) Win32: Update the server to use Winsock 2. Specifically, link with

ws2_32.lib rather than wsock32.lib. This gives us access to

WSADuplcateSocket() in addition to some other enhanced comm APIs.

Win 95 users may need to update their TCP/IP stack to pick up

Winsock 2. (See http://www.microsoft.com/windows95/downloads/)

[Bill Stoddard stoddard@raleigh.ibm.com]

*) Win32: Redirect CGI script stderr (script debug info) into the

error.log when CGI scripts fail. This makes Apache on Win32

behave more like Unix.

[Bill Stoddard stoddard@raleigh.ibm.com]

*) Fixed `httpd' usage display: -D was missing.

[Ralf S. Engelschall] PR#4614

*) Fix `make r' test procedure in src/regex/: ap_isprint was not found.

[Ralf S. Engelschall] PR#4561, PR#4562

*) OS/2: Fix problem with accept lock semaphores where server would die with

"OS2SEM: Error 105 getting accept lock. Exiting!"

[Brian Havard] PR#4505

*) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.

[Randy Terbush <randy@covalent.net>]

*) Add the new mass-vhost module (mod_vhost_alias.c) developed and

used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]

*) Better GCC detection for DSO flags under Solaris 2 where the `cc'

command potentially _is_ GCC. [Ralf S. Engelschall]

*) Fix apxs build issues on AIX

[Rasmus Lerdorf <rasmus@raleigh.ibm.com>]

*) DocumentRoot Checking: Under previous versions, when Apache

first started up, it used to do a stat of each DocumentRoot to

see if it existed and was a directory. If not, then an error

message was printed. THIS HAS BEEN DISABLED. If DocumentRoot

does not exist, you will get error messages in error_log. If

the '-t' command line option is used (to check the configuration)

the check of DocumentRoot IS performed. An additional command

line option, '-T', has been added if you want to avoid the

DocumentRoot check even when checking the configuration.

[Jim Jagielski]

*) Win32: The query switch "apache -S" didn't exit after showing the

vhost settings. That was inconsistent with the other query functions.

[Bill Stoddard - Fixed by Martin on Unix in 1.3.4]

*) Win32: Changed behaviour of apache -k restart.

Previously, the server would drain all connections in the stack's

listen queue before honoring the restart. On a busy server, this

could take hours. Now, a restart is honored almost immediately.

All connections in Apache's queues are handled but connections in

the stack's listen queue are discarded. Restart triggered by

MaxRequestPerChild is unchanged.

[Bill Stoddard <stoddard@raleigh.ibm.com>]

*) Win32: Eliminated unnecessary call to wait_for_multiple_objects in

the accept loop. Good for a 5% performance boost. Cleaned up

parent/child process management code.

[Bill Stoddard <stoddard@raleigh.ibm.com>]

*) Added ceiling on file size for memory mapped files.

[John Giannandrea <jg@meer.net>] PR#4122

*) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which

has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528

[Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]

*) Determine AP_BYTE_ORDER for ap_config_auto.h and already

use this at least for Expat. [Ralf S. Engelschall]

*) Allow .module files to specify libraries with Lib:.

[Ben Laurie]

*) Allow SetEnvIf[NoCase] to test environment variables as well

as header fields and request attributes. [Ken Coar]

*) Fix mod_autoindex's handling of ScanHTMLTitles when file

content-types are "text/html;parameters". PR#4524 [Ken Coar]

*) Remove "mxb" support from mod_negotiation -- it was a draft feature

never accepted into any standard, and it opens up certain DoS

attacks. [Koen Holtman <Koen.Holtman@cern.ch>]

*) TestCompile updated. We can now run programs and output the

results during the Configure process. [ Jim Jagielski]

*) The source is now quad (long long) aware as needed. Specifically,

the Configure process determines the correct size of off_t and

*void. When the OS/platform/compiler supports quads, ap_snprintf()

provides for the 'q' format qualifier (if quads are not available,

'q' is silently "demoted" to long). [Jim Jagielski]

*) When the username or password fed to htpasswd is too long, include the

size limit in the error message. Also report illegal characters

(currently only ':') in the username. Add the size restrictions

to the man page. [Ken Coar]

*) Fixed the configure --without-support option so it doesn't result in

an infinite loop. [Marc Slemko]

*) Piped error logs could cause a segfault if an error occured

during configuration after a restart.

[Aidan Cully <aidan@panix.com>] PR#4456

*) If a "Location" field was stored in r->err_headers_out rather

than r->headers_out, redirect processing wouldn't find it and

the server would core dump on ap_escape_html(NULL). Check both

tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message

if Location isn't set. [Doug MacEachern, Ken Coar]

*) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy

of the Expat 1.0.2 distribution. [Greg Stein]

*) Replace regexec() calls with calls to a new API stub function

ap_regexec(). This solves problems with DSO modules which use the regex

library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]

*) Add 'Request_Protocol' special keyword to mod_setenvif so that

environment variables can be set according to the protocol version

(e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

*) Add DSO support for OpenStep (Mach 4.2) platform.

[Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997

*) Fix sed regex for generating ap_config_auto.h in src/Configure.

[Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373

*) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with

their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372

*) Better DSO flags recognition on NetBSD platforms using ELF.

[Todd Vierling <tv@pobox.com>] PR#4310

*) Always log months in english format for %t in mod_log_config.

[Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679

*) Support for server-parsed and multiview-determined ReadmeName and

HeaderName files in mod_autoindex. Removed the restriction on

"/"s in ReadmeName and HeaderName directives since the *sub_req*

routines will deal with the access issues. (It's now possible to

have {site|group|project|customer|...} wide readmes and headers.)

[Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,

*) When stat() fails, don't assume anything about the contents of

the struct stat. [Ed Korthof <ed@bitmechanic.com>]

*) It's OK for a semop to return EINTR, just loop around and try

again. [Dean Gaudet]

*) Fix configuration engine re-entrant hangups, which solve a

handful of problems seen with mod_perl <Perl> configuration sections

[Salvador Ortiz Garcia <sog@msg.com.mx>]

*) Mac OS and Mac OS X Server now use the appropriate custom layout

by default when building with APACI; allow for platform-specific

variable defaults in configure. [Wilfredo Sanchez]

*) Do setgid() before initgroups() in http_main; some platforms

zap the grouplist when setgid() is called. This was fixed in

suexec earlier, but the main httpd code missed the change.

[Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579

*) Add recognition of .tgz as a gzipped tarchive.

[Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364

*) mod_include's fsize/flastmod should allow only relative paths, just

like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]

*) OS/2: Add support for building loadable modules using DLLs.

[Brian Havard]

*) Add iconsdir, htdocsdir, and cgidir to config.layout.

[Wilfredo Sanchez]

*) Fix minor but annoying bug with the test for Configuration.tmpl

being newer than Configuration so that it is less likely to fail

when using APACI and shadow sources. [Wilfredo Sanchez]

*) PORT: Add initial support for Mac OS (versions 10.0 and

greater). Use Mac OS X Server layout for now. Clean up dyld code

in unix/os.c, and don't install the dyld error handlers, which

are no longer needed in Mac OS. [Wilfredo Sanchez]

*) Rename Rhapsody layout to "Mac OS X Server". Change install

locations to appropriate ones for user-built (as opposed to

system) installs. [Wilfredo Sanchez]

*) Modify mod_autoindex's handling of AddDescription so that the

behaviour matches the documentation. [Ken Coar] PR#1898, 3072.

*) Add functionality to the install-bindist.sh script created by

binbuild.sh to use tar when copying distribution files to the

serverroot. This allows upgrading an existing installation

without nesting the new distribution in the old.

install-bindist.sh now detects the local perl5 path to install

apxs and dbmmanage with proper path to perl interpreter.

Add an install-binsupport target which copies the source files

for apxs and dbmmanage to bindist to allow these scripts to

be properly installed relative to the destination serverroot.

[Randy Terbush, Covalent Technologies, randy@covalent.net]

*) Fix intermittent SEGV in ap_proxy_cache_error() in

src/modules/proxy_util.c where a NULL filepointer and

temporary filename were closed and unlinked.

[Graham Leggett <minfrin@sharp.fm>,

*) Fix inconsistent error messages reported by mod_proxy.

[Graham Leggett <minfrin@sharp.fm>]

*) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a

connection is aborted. [Brian Havard]

*) Force the LANG envariable to the known state of "C" so that we

have assurance about how string manipulators (e.g., tr) will

function. [Ken Coar] PR#1630

*) Add a directive to allow customising of the tracking cookie name.

[Ken Coar] PR#2921, 4303

*) Add "force-no-vary" envariable to allow servers to work around

clients that choke on "Vary" fields in the response header.

[Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118

*) Fixed a bug in mod_dir that causes a child process will infinitely

recurse when it attemps to handle a request for a directory wnd the

value of the DirectoryIndex directive is a single dot. Also likely

to happen for anyother values of DirectoryIndex that will map back

to the same directory. The handler now only considers regular files

as being index candidates. No PR#s found.

[Raymond S Brand <rsbx@rsbx.net>]

*) Ease configuration debugging by making TestCompile fall back to

using "make" if the $MAKE variable is unset [Martin Kraemer]

*) Fixed the ServerSignature directive to work as documented.

[Raymond S Brand <rsbx@rsbx.net>] PR#4248

*) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand

<rsbx@rsbx.net>]

*) Add APACI --without-execstrip option which can be used to disable the

stripping of executables on installation. This is very important for DSO

and debugging situations. [Ralf S. Engelschall]

[Ben Laurie]

*) Correct an apparent typo: on the Windows and MPE platforms, the

htpasswd utility was limiting passwords to only 8 characters.

[Ken Coar]

*) EBCDIC platforms: David submitted patches for two bugs in the

MD5 digest port for EBCDIC machines:

a) the htdigest utility overwrote the old contents of the digest file

b) the Content-MD5 header value (ContentDigest directive) was wrong

when the returned file was not converted from EBCDIC, but was a

binary (e.g., image file) in the first place.

[David McCreedy <mccreedy@us.ibm.com>]

*) support/htpasswd now permits the password to be specified on the

command line with the '-b' switch. This is useful when passwords

need to be maintained by scripts -- particularly in the Win32

environment. [Ken Coar]

*) Win32: Win32 multiple services patch. Added capability to install and

run multiple copies of apache as individual services.

Example 1:

apache -n apache1 -i -f c:/httpd.conf

Installs apache as service 'apache1' and associates c:/httpd.conf

with that service.

net start apache1

Starts apache1 service.

net stop apache1

Stops apache1 service

Example 2:

apache -n apache2 -i

Installs apache as service 'apache2'. httpd.conf is located under

the default server root (/apache/conf/httpd.conf).

net start apache2

Starts apache2 service.

Example 3:

apache -n apache3 -i -d c:/program files/apache

Install apache as service 'apache3' and sets server root to

c:/program files/apache.

Example 4:

apache -n apache2 -k restart

Restart apache2 service

[Keith Wannamaker, Ken Parzygnat, Bill Stoddard]

*) Correct the signed/unsigned character handling for the MD5 routines;

mismatches were causing compilation problems with gcc -pedantic and

in the TPF cross-compilation. [Ken Coar]

*) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving

a roughly 5 fold speed up. [Brian Havard]

*) proxy ftp: instead of using the hardwired string "text/plain" as

a fallback type for files served by the ftp proxy, use the

ap_default_type() function to determine the configured type.

This allows for special configurations like

<Directory proxy:ftp://some.host>

DefaultType gargle/blurb

</Directory>

Additionally, add the Content-Encoding: header to FTP proxy replies

when the encoding is defined (by the AddEncoding directive).

Because it was missing, it was almost impossible to browse compressed

files using the FTP proxy (works now perfectly in Communicator).

The ftp proxy now also returns the Date: and Server: header lines (if not

much else... This code is "somewhat" broken) like normal requests do.

[Martin Kraemer]

*) Be more smart in APACI's configure script when determining the UID/GID

for User/Group directives and use the determined UID/GID to initialize

the permissions on the proxycachedir.

[Dirk-Willem van Gulik, Ralf S. Engelschall]

*) Changed the forking-prior-to-cleanup in the proxy module to first

check wether it actually needs to collect garbage. This reduces

the number of fork()s from one/request to just the odd one an hour.

[Dirk-Willem van Gulik]

*) Added proxy, auth and header support to src/support/ab.c. Added a

README file to src/support/

[Dirk-Willem van Gulik]

*) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.

*) Add support for DSO module compilation on BSD/OS 3.x.

[Randy Terbush, Covalent Technologies]

*) Fix sed-substitutions in `make install': path elements like `httpd/conf'

(for instance from an APACI configure --sysconfdir=/etc/httpd/conf

option) were substituted with $(TARGET).conf, etc. Same for other strings

with dots where the dot wasn't matched as plain text.

[Ralf S. Engelschall]

*) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]

*) Fix verbose output of APACI configure (option -v)

[Martin Kraemer, Ralf S. Engelschall]

Changes with Apache 1.3.6

*) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]

Changes with Apache 1.3.5 [not released]

*) M_INVALID needed a value within the scope of METHODS so that unknown

methods can be access controlled. [Roy Fielding] PR#3821

*) Added PassAllEnv; makes server's entire environment available

to CGIs and SSIs executed within directive's scope. [Ken Coar]

*) ap_uuencode() always added two trailing '='s and encoding of

8 bit characters on a machine with signed char may produced

incorrect results. Additionally ap_uuencode() should now

work correctly on EBCDIC platforms.

[Ronald Tschal�r <ronald@innovation.ch>] PR#3411

*) WIN32: Binary installer now runs the configuration DLL before

the reboot prompt (which is only given if MSVCRT.DLL system

DLL is new or updated). This should avoid the configuration

directory being empty after installation. [Paul Sutton]

PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

*) WIN32: Binary installer now creates Start menu options to start

and stop Apache as a console application and to uninstall

the Apache service on NT. [Paul Sutton] PR#3741

*) WIN32: Apache.exe now contains an icon. [Paul Sutton]

*) PORT: Switch back to using fcntl() locking on Linux -- instabilities

have been reported with flock() locking (probably related to kernel

version). [Dean Gaudet] PR#2723, 3531

*) Using APACI, the main config file (usually httpd.conf) was

not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

<wsanchez@apple.com>]

*) PORT: AIX does not require the SHARED_CODE "hack"

[Ryan Bloom <rbb@raleigh.ibm.com>]

*) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)

avoidance code added in 1.3.3.

[Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872

*) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros

for 8-bit safeness. [Dean Gaudet]

*) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs

because SPARCs have a small machine-specific maximum size for the Global

Offset Table which is often exceeded when compiling one of the larger

third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977

*) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

DSO/DLL section because it's a directive from mod_status and isn't

available before the DLL of mod_status is loaded.

[Martin POESCHL <mpoeschl@gmx.net>] PR#3936

*) SECURITY: Fix a bug in the calculation of the buffer size for the line

continuation facility in Apache's configuration files which could

lead to a buffer overflow situation.

[Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617

*) Make documentation and error messages of APACI's --activate-module=FILE

option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995

*) Fix the gcc version check (for enabling the `inline' facility) to

really support all future gcc versions >= 2.7 until we know more.

[John Tobey <jtobey@banta-im.com>] PR#3983

*) Let APACI's configure script correctly complain for unknown --enable-XXX

and --disable-XXX options. [Ralf S. Engelschall] PR#3958

*) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also

against libap.a and use its ap_snprintf() instead of sprintf() to avoid

possible buffer overflows. [Ralf S. Engelschall]

*) Remove no longer used non-API function ap_single_module_init().

[Ralf S. Engelschall]

*) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.

[Wilfredo Sanchez]

*) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order

to make platform installations easier. [Wilfredo Sanchez]

*) In configure, do not append the target name to the directory path if

the path already contains "apache". [Ralf S. Engelschall]

*) SIGPIPE is now ignored by the server core. The request write routines

(ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now

correctly check for output errors and mark the connection as aborted.

Replaced many direct (unchecked) calls to ap_b* routines with the

analogous ap_r* calls. [Roy Fielding]

*) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and

DBM format mapfiles now uses a 4-way hash table with LRU functionality.

Furthermore map lookups for non-existent keys are now cached as well.

Additionally "txt" maps are now parsed with simple string functions

instead of using ap_pregcomp(). As a side effect a bug that prevented

the usage of keys containing the "," character was fixed.

The changes drastically improve the performance when large rewrite maps

are in use.

[Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

*) Added ap_sub_req_method_uri() for doing a subrequest with a method

other than GET, and const'd the definition of method in request_rec.

[Greg Stein]

*) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]

*) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate

when the OS allows a DOS drive letter within pathnames. [Brian Havard]

*) Add %V to mod_log_config, this logs the hostname according to the

UseCanonicalName setting (this is the pre-1.3.4 behaviour of

%v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]

*) Add support for \n and \t to mod_log_config, can be used to produce

more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]

*) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

*) Added informative error messages for failed munmap() and fseek() calls

in http_core.c. [John Bley, Roy Fielding]

*) Added some informative error messages for some failed malloc()

calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]

*) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()

is removed. This allows <Directory proxy:*> directives to work and

prevents invalid requests from killing the process.

[Brian Havard <brianh@kheldar.apana.org.au>]

*) Reorganised FAQ document.

[Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497

*) src/support/: The ApacheBench benchmark program was overhauled by

David N. Welton: you can now have it generate an HTML TABLE, presumably

for integration into other HTML sources. David updated the ab man page

as well and added some missing descriptions. Thanks!

[David N. Welton <davidw@prosa.it>]

*) Win32: The filename validity checker now allows filenames containing

characters in the range 0x80 to 0xff (for example accented characters).

[Paul Sutton] PR#3890

*) Added conditional logging based upon environment variables to

mod_log_config. mod_log_referer and mod_log_agent

are now deprecated. [Ken Coar]

*) Allow apache acting as a proxy server to relay the real

reason of a failure to a client rather than the "internal

server error" it does currently. The general exposure mechanism

can be triggered by any module by setting the "verbose-error-to"

note to "*"; this allows more than just proxy errors to be exposed.

[Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086

*) Moved man pages for ab and apachectrl to section 8.

[Wilfredo Sanchez, Roy Fielding]

*) Added -S option to install.sh so that options can be passed to

strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]

*) Tweak modules Makefile generated by Configure so that it handles

the test case of no modules being selected. [chaz@reliant.com]

*) Added a <LimitExcept method ...> sectioning directive that allows

the user to assign authentication control to any HTTP method that

is *not* given in the argument list; i.e., the logical negation

of the <Limit> directive. This is particularly useful for controlling

access on methods unknown to the Apache core, but perhaps known by

some module or CGI script. [Roy Fielding, Tony Finch]

*) Prevent apachectl from complaining if the PIDFILE exists but

does not contain a process id, as might occur if the server is

being rapidly restarted. [Wilfredo Sanchez]

*) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]

*) Entity tag comparisons for If-Match and If-None-Match were not being

performed correctly -- weak tags might cause false positives. Also,

strong comparison wasn't properly enforced in all cases.

[Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

*) OS/2: Supply OS/2 error code instead of errno on semaphore errors.

[Brian Havard]

*) Work around a bug in Lynx regarding its sending "Negotiate: trans"

even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]

*) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()

to util.c for parsing an HTTP header field value to extract the next

list item, taking into account the possible presence of nested comments,

quoted-pairs, and quoted-strings. ap_get_list_item() also removes

insignificant whitespace and lowercases non-quoted tokens.

[Roy Fielding] PR#2065

*) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status

code different from 500. This allows the proxy to, e.g., return

"403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455

*) Fix ordering of language variants for the case where the traditional

negotiation algorithm is being used with multiple language variants

and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688

*) Do not round the TCN quality calculation to 5 decimal places,

unlike RFC 2296, because the calculation might need 12 decimal places

to get the right result. [Roy Fielding]

*) Remove unused code to disable transparent negotiation when

negotiating on encoding only, as we now handle encoding too

(though this is nonstandard for TCN), remove charset=ISO-8859-1

fiddle from the fiddle-averse RVSA comparison, and fix bugs in

some debugging statements within mod_negotiation. [Koen Holtman]

*) Fixed a rare memory corruption possibility in mod_dir if the index

file is negotiable and no acceptable variant can be found.

[Dean Gaudet, Roy Fielding, Martin Kraemer]

*) Win32: Add new config directive, ScriptInterpreterSource, to enable

searching the Win32 registry for script interpreters.

[Bill Stoddard]

*) Win32: The compiled-in default filename for the error log is now

error.log, which matches the default in the distributed httpd.conf.

[Paul Sutton]

*) Win32: Any error messages from -i or -u command line options are now

displayed on the console output rather than sent to the error log.

Also the "Running Apache..." message is not output unless Apache is

going to serve requests. [Paul Sutton]

*) Rework the MD5 authentication scheme to use FreeBSD's algorithm,

and use a private significator ('$apr1$') to mark passwords as

being smashed with our own algorithm. Also abstract the password

checking into a new ap_validate_password() routine. [Ken Coar]

*) Win32: The filename validity checker now allows "COM" but refuses

access to "COM1" through "COM4". This allows filenames such

as "com.name" to be served. [Paul Sutton] PR#3769.

*) BS2000: Adapt to the new ufork() system call interface which will

make subtasking easier on the OSD/POSIX mainframe environment.

[Martin Kraemer]

*) Add a compatibility define for escape_uri() -> ap_escape_uri() to

ap_compat.h. [David White <david@persimmon.com>] PR#3725

*) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.

use `.db' instead of `.pag' not only for FreeBSD, but also when

the NDBM library looks like Berkeley-DB based.

[Ralf S. Engelschall] PR#3773

*) Add ability to handle DES or MD5 authentication passwords.

[Ryan Bloom <rbb@Raleigh.IBM.Com>]

*) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]

*) SECURITY: Avoid some buffer overflow problems when escaping

quoted strings. (This overflow was on the heap and we believe

impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]

*) Let src/Configure be aware of CFLAGS options starting with plus

signs as it's the case for the HP/UX compiler.

[Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681

*) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)

and check to see if the tar we wind up with supports '-h'.

[Jim Jagielski] PR#3671

*) A consistent and conservative style for all shell scripts has been

implemented. Basically, all shell string tests use the traditional

hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'

to protect against bare null variable strings (ie: wrapping both

sides with double quotes and prepending 'x'). 'x' was chosen

because it's more universal and hopefully easier for old shell

prgrammers, as well as being easier to search for in 'vi' (/x\$) :)

[Jim Jagielski]

*) The status module now prints out both the main server generation as

well as the generation of each process. Also, the vhost info is

printed with '?notable'. [Jim Jagielski]

*) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral

and this makes its functions available to things in src/support.

[Ken Coar]

Changes with Apache 1.3.4

*) Renamed macros status_drops_connection to ap_status_drops_connection

and vestigial scan_script_header to ap_scan_script_header_err,

mostly for aesthetic reasons. [Roy Fielding]

*) The query switch "httpd -S" didn't exit after showing the

vhost settings. That was inconsistent with the other query functions.

[Martin Kraemer]

*) Moved the MODULE_MAGIC_COOKIE from before the versions and

filename to the end of the STANDARD_MODULE_STUFF. Its

presence at the beginning prevented reporting of the filename

for modules compiled before 1 January 1999. [Ken Coar]

*) SECURITY: ap_os_is_filename_valid() has been added to Win32

to detect and prevent access to special DOS device file names.

[Paul Sutton, Ken Parzygnat]

*) WIN32: Created new makefiles Makefile_win32.txt (normal build)

and Makefile_win32_debug.txt (debug build) that work on Win95.

Run each of the following from the src directory:

nmake /f Makefile_win32.txt # compiles normal build

nmake /f Makefile_win32.txt install # compiles and installs

nmake /f Makefile_win32.txt clean # removes compiled junk

nmake /f Makefile_win32_debug.txt # compiles debug build

nmake /f Makefile_win32_debug.txt install

nmake /f Makefile_win32_debug.txt clean

[Roy Fielding]

*) Added binbuild.sh and findprg.sh helpers to make it easier for us

to build binary distributions. [Lars Eilebrecht]

*) IndexOptions SuppressColumnSorting only turned off making

the column headers anchors; you could still change the display

order by manually adding a '?N=A' or similar query string to the

URL. Now SuppressColumnSorting locks in the sort order so

it can't be overridden this way. [Ken Coar]

*) Added IndexOrderDefault directive to supply a default sort order

for FancyIndexed directory listings. [Ken Coar] PR#1699

*) Change the ap_assert macro to a variant that works on all platforms.

[Richard Prinz <richard.prinz@cso.net>] PR#2575

*) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't

search for an underscore on dlsym() (as it's already the case

for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462

*) Small fix for mod_env.html: The module was documented as to be _not_

compiled into Apache per default, although it _IS_ compiled into

Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572

*) Instead of fixing a bug in the generation procedure for config.status (a

backslash was missing) we remove the bug together with it's complete

context because the special cases of the past can now no longer occur

because of the recent magic for the --with-layout default.

[Ralf S. Engelschall] PR#3590

*) Make top-level Makefile aware of a parallel build procedures (make -j) by

making sure the src/support/ tools are _forced_ to be build last (they

depend on other libraries).

[Markus Theissinger <markus.theissinger@gmx.de>]

*) Fix installation procedure: Now that os-inline.c is actually used (a

recently fixed bug prevented this) we need to also install os-include.c

in addition to os.h into the PREFIX/include/ location or building of

module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527

*) Added MODULE_MAGIC_COOKIE as the first field in a module structure to

allow us to distinguish between a garbled DSO (or even a file which isn't

an Apache module DSO at all) and a DSO which doesn't match the current

Apache API. [Ralf S. Engelschall] PR#3152

*) Two minor enhancements to mod_rewrite: First RewriteRule now also

supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to

match case insensitive (this especially avoids nasty patterns like

`[tT][eE][sS][tT]'). Second two additional internal map functions

`escape' and `unescape' were added which can be used to escape/unescape

to/from hex-encodings in URLs parts (this is especially useful in

combination with map lookups).

[Magnus Bodin, Ian Kallen, Ralf S. Engelschall]

*) Renamed the macro escape_uri() to ap_escape_uri() which was

forgotten (because it was a macro) in the symbol renaming process.

[Ralf S. Engelschall]

*) Fix some inconsistencies related to the scopes of directives. The only

user visible change is that the directives `UseCanonicalName' and

`ContentDigest' now use the (more correct) `Options' scope instead of

(less correct) `AuthConfig' scope. [Ralf S. Engelschall]

*) Using DSO, the Server token was being mangled. Specifically, the

module's token was being added first before the Apache token. This

has been fixed. [Jim Jagielski]

*) Major overhaul of mod_negotiation.c, part 2.

- properly handle "identity" within Accept-Encoding.

- allow encoded variants in RVSA negotiation and let them appear in

the Alternates field using the non-standard "encoding" tag-list.

- fixed both negotiation algorithms so that an explicitly accepted

encoding is preferred over no encoding if "identity" is not

included within Accept-Encoding.

- added ap_array_pstrcat() to alloc.c for efficient concatenation

of large substring sequences.

- replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.

[Roy Fielding]

*) Major overhaul of mod_negotiation.c, part 1.

- cleanups to mod_negotiation comments and code structure

- made compliant with HTTP/1.1 proposed standard (rfc2068) and added

support for everything in the upcoming HTTP/1.1

revision (draft-ietf-http-v11-spec-rev-06.txt).

- language tag matching also handles tags with more than 2

levels like x-y-z

- empty Accept, Accept-Language, Accept-Charset headers are

processed correctly; previously an empty header would make all

values acceptable instead of unacceptable.

- allowed for q values in Accept-Encoding

- added support for transparent content negotiation (rfc2295 and

rfc2296) (though we do not implement all features in these drafts,

e.g. no feature negotiation). Removed old experimental version.

- implemented 'structured entity tags' for better cache correctness

(structured entity tags ensure that caches which can deal with Vary

will (eventually) be updated if the set of variants on the server

is changed)

- this involved adding a vlist_validator element to request_rec

- this involved adding the ap_make_etag() function to the global API

- modified guessing of charsets used by Apache negotiation algorithm

to guess 'no charset' if the variant is not a text/* type

- added code to sort multiviews variants into a canonical order so that

negotiation results are consistent across backup/restores and mirrors

- removed possibility of a type map file resolving to another type map

file as its best variant

[Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987

*) RFC2396 allows the syntax http://host:/path (with no port number)

but the proxy disallowed it (ap_proxy_canon_netloc()).

[David Kristol <dmk@bell-labs.com>] PR#3530

*) When modules update/modify the file name in the configfile_t structure,

syntax errors will report the updated name, not the original one.

[Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573

*) Correct some filename case assumptions from WIN32 to

CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]

*) For %v log ServerName regardless of the UseCanonicalName

setting (similarly for %p). [Dean Gaudet]

*) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL

rather late (too late for some invocations of TestCompile).

This improves the make environment available to TestCompile and

the *.module scripts. [Martin Kraemer]

*) The hashbang emulation code in ap_execve.c would interpret

#!/hashbang/scripts correctly, but failed to fall back to a

standard shell for scripts which did NOT start with #!

Now SHELL_PATH is started in these cases. [Martin Kraemer]

*) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]

PR#3336

*) Update APXS manual page: some -q option arguments were missing

and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553

*) Cleanup the command line options: `-?' was documented to show

the usage list but does it with an error because `?' is not a valid

command. OTOH a lot of users expect `-h' to print such a usage list and

instead are annoyed for ages by our huge unreadable list of directives.

So we now changed the command line options this way:

1. `-L' => `-R'

Intent: we need `-L' to be free, and `-R' for the DSO run-time path is

very similar to the popular linker option.

2. `-h' => `-L'

Intent: while -l gives the small list of modules, -L now gives the

large list of directives implemented by these modules. This is also

consistent with -v (short version info) and -V (large version info).

3. `-?' => `-h'

Intent: it's now the expected option ;-)

The manual page was adjusted accordingly.

[Ralf S. Engelschall] PR#2714

*) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC

wasn't defined. [Rick Franchuk <rickf@transpect.net>]

*) Removed recently introduced bugs and disfigurements in APACI:

o fixed argument line processing: using $args was broken: It was not

initialized and using args="$args $apc_option" and even args="$args

\"$apc_option\"" fails in the second processing round for any arguments

containing whitespaces. The only correct way is to use the construct

"$@" (but not possible here) or iterate _both_ times over the implicit

argument line (no argument to for-loop) which is what we now use.

o make --with-layout=Apache the default without creating

redundancy (copying the --with-layout block in the argument parsing

loop). We achieve this by using the "$@" construct together with the

`set' command to prepend --with-layout=Apache to the command line in

case --with-layout is not used.

o fixed auto-suffix handling now that config.layout exists.

Paths which are auto-suffixed are marked with a trailing plus sign in

config.layout and every path now can be marked this way (not only the

four paths for which we do it currently). Additionally the suffix is

no longer a static one. Instead it's now `/<target>' where <target> is

the argument of the --target option or per default `httpd'.

o allow also tabs (and only spaces) where we match whitespaces

o various fixes and cleanups related to used shell coding style

o made Jim happy by replacing `Written by' with `Initially written by' ;-)

o trimmed output of --help to fit into 80 columns

[Ralf S. Engelschall]

*) Added two new core API functions, ap_single_module_configure() and

ap_single_module_init(), which are now used by mod_so to configure a module

after loading. [Ralf S. Engelschall]

*) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and

SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section

of ap_config.h to allow serialized accept for multiport listens.

[Roy Fielding, Curt Sampson] PR#3120

*) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section

of ap_config.h that would skip several defines if DEFAULT_GROUP

was overridden. [Roy Fielding]

*) PORT: The I86 version of DGUX has support for strncasecmp and

strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247

*) Fix ordering of definitions in ap_config.h so that ap_inline is

defined before it might be used. [Victor Khimenko]

*) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).

[Tom Serkowski <tks@bsdi.com>] PR#3453

*) Make generation of src/Configuration.apaci more robust: It failed to

differenciate between modules when one module name was a postfix of

another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even

just XXX (think about totally non-standard names like "apache_ssl", too).

[Ralf S. Engelschall] PR#3380

*) In src/Configure remove the SERVER_SUBVERSION support (already deprecated

since 1.3b7) and make whitespace handling more robust (it failed horrible

when whitespaces were present in the arguments of -D options).

[Ralf S. Engelschall] PR#3240

*) Add APACI --shadow=DIR variant (in addition to --shadow). This now first

creates an external package shadow tree in DIR before the local build

shadow tree is generated under DIR. This way one can have the extracted

Apache distribution tree read-only on NFS or CDROM and still build Apache

from these sources. An automatically triggered VPATH-like mechanism is

provided through the TOP variable, too.

[Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]

*) Fix negotiation so that a Vary response header is correctly

generated when, for a particular dimension, variants only vary

in having or not having a value for that dimension. [Paul Sutton]

*) Fix negotiation so that we prefer an encoded variant over an

unencoded variant if the user-agent explicitly says it can

accept that encoding. Previously we always preferred the unencoded

variant.

[Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447

*) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized

and the usage page was inconsistent with the functionality and manpage.

[Ralf S. Engelschall]

*) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.

They can occur multiple times and their arguments (`xxx') are passed AS

IS to the compiler/linker command. [Ralf S. Engelschall]

*) Fixed possible (but harmless in practice) bug in the DBM lookup

procedure of mod_rewrite: very long keys were truncated.

[Ralf S. Engelschall]

*) Added a generic --with-layout=[FILE:]ID option. ID here is a layout

identifier, currently "Apache" and "GNU" are pre-defined in the file

config.layout. Custom layouts are possible by using FILE:ID as the

argument where the layout ID is taken from FILE.

The config.layout file consists of <Layout ID>..</Layout> sections

where inside those sections "path_variable: path_value" pairs can be

specified. These lines are converted to path_variable='path_value'.

*) Add a DefaultLanguage directive so that files missing a language

extension (e.g., .fr, .de) can be labelled as being some other

default language. DefaultLanguage can appear in <Directory> and

<Files> containers as well as .htaccess files. [Paul Sutton]

PR#1180

*) Fix TARGET configuration when configuring and installing using

APACI configure. TARGET now defines the basename of the configuration

file, startup script, manual page, etc. log_error_core() now reports

the server binary name given by argv[0]. TARGET can now also be defined

with --target=TARGET parameter passed to APACI configure.

[Ralf Engelschall, Randy Terbush]

*) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC

rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

*) ap_md5_binary() was using sprintf() rather than a table lookup

to convert binary bytes to hex digits.

[Ronald Tschal�r <ronald@innovation.ch>] PR#3409

*) Fix SEGV in TCN negotiation if no variants are acceptable.

[Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>] PR#1987

*) API: ap_exists_config_define() function is now "public" [Doug MacEachern]

*) Fix documentation of `Action' directive: It can activate a CGI script

when either a handler or a MIME content type is triggered by the request.

*) Add APACI --suexec-docroot and --suexec-logfile options which can be

used to set the document root directory (DOC_ROOT) and the suexec

logfile (LOG_EXEC), respectively. Additionally the --layout option

was changed to show more information about the suEXEC setup.

*) Enabled all of the WebDAV method names for use by third-party

modules, Limit, and Script directives. That includes PATCH,

PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

Improved mod_actions.c so that it can use any of the methods

mod_foo with the begin of the module list, i.e. it `moves' the module to

the begin of the list (gives it lowest priority). And second foo:END

which permutes mod_foo with the end of the module list, i.e. it `moves'

the module to the end of the list (gives it highest priority).

Changes with Apache 1.3.3

*) Added a complete implementation of the Expect header field as

specified in rev-05 of HTTP/1.1. Disabled the 100 Continue

response when we already know the final status, which is mighty

useful for PUT responses that result in 302 or 401. [Roy Fielding]

*) Remove extra trailing whitespace from the getline results as part

of the protocol processing, which is extra nice because it works

between continuation lines, is almost no cost in the normal case

of no extra whitespace, and saves memory. [Roy Fielding]

*) Added new HTTP status codes and default response bodies from the

revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and

HTTP Extension Framework (510) specifications. Did not add the

WebDAV 424 and 425 codes because they are bogus. We don't use any

of these codes yet, but they are now available to 3rd-party modules.

platform to make the braindead HPUX linker happy. Notice, for the module

DSOs we don't have to use this, because these are loaded manually (and

not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]

*) Make PrintPath work generically instead of having one version

strictly for OS/2. [Jim Jagielski, Brian Havard]

*) Fix the recently introduced C header file checking: We now use the C

pre-processor pass only (and no longer the complete compiler pass) to

determine whether a C header file exists or not. Because only this way

we're safe against inter-header dependencies (which caused horrible

portability problems). The only drawback is that we now have a CPP

configuration variable which has to be determined first (we do a similar

approach as GNU Autoconf does here). When all fails the user still has

the possibility to override it manually via APACI or src/Configuration.

As a fallback for the header check itself we can directly check the

existance of the file under /usr/include, too.

because our GuessOS is still unaware of Digital UNIX versions and the

-msym is just to optimize the DSO statup time a little bit it's safe and

best when we leave it out now. [Ralf S. Engelschall] PR#2969

*) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()

functions: First all three functions no longer fail on strings containing

"%" chars and second ap_log_printf() no longer does a double-formatting

(instead it directly passes through the message to be formatted to the

real internal formatting function). [Ralf S. Engelschall] PR#2941

*) Allow "Include" directives anywhere in the server config

files (but not .htaccess files). [Ken Coar] PR#2727

*) The proxy was refusing to serve CONNECT requests except to

port 443 (https://) and 563 (snews://). The new AllowCONNECT

directive allows the configuration of the ports to which a

CONNECT is allowed. [Sameer Parekh, Martin Kraemer]

*) mod_expires will now act on content that is not sent from a file

on disk. Previously it would never add an Expires: header to

any response that did not come from a file on disk; the only

case where it still doesn't (and can't) add one for that type of

content is if you are using a modification date based setting.

[Marc Slemko, Paul Phillips <paulp@go2net.com>]

*) Problems encountered during .htaccess parsing or CGI execution

that lead to a "500 Server Error" condition now provide explanatory

text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.

[Ken Coar] PR#1291

*) Add NameWidth keyword to IndexOptions directive so that the

width of the filename column is customisable. [Ken Coar, Dean Gaudet]

PR#1949, 2324.

*) Recognize lowercase _and_ uppercase `uname' results under

SCO OpenServer. [David Coelho <drc@ppt.com>]

*) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be

a common problem of (mis-administrated?) IIS servers, make the apache

proxy immune to these errors (and ignore the duplicates, but log

the fact to error_log). [Martin Kraemer], after the proposal in PR#2914

*) The <IfModule and <IfDefine block starting directives now only

allow exactly one argument. Previously, the optional negation

character '!' could be separated by whitespace without a syntax

error being reported, albeit defeating the IfModule functionality

(enclosed directives would ALWAYS be executed). By using the

stricter syntax, these hard-to-track errors can be avoided.

[Martin Kraemer]

*) Simplify handling of IndexOptions in mod_autoindex -- and BTW

cause the standalone FancyIndexing directive to logically OR

into any existing IndexOptions settings rather than wiping

them out. [Ken Coar]

*) Changes in ftp proxy: make URL parsing simpler by using the

parsed_uri stuff.

+ Add display of the "current directory" in cases where it's

different from the supplied path (e.g., ftp://user@host/ lives

in /home/user, not in /, therefore clicking on "../" in the

starting directory might send us to /home/).

+ When ftp login fails, (esp. when a user name was part of the

URL already), we now return [401 Unauthorized ] to allow the

browser to pop up an authorization dialog. This makes passwords

slightly less visible (they don't appear in the regular log files)

and implements a functionality that other www proxy servers

already offered.

[Martin Kraemer]

*) Triggered by the recent "Via:" header changes, the proxy module would

dump core for replies with invalid headers (e.g., duplicate

"HTTP/1.0 200 OK" lines). These errors are now logged and the

core dump is avoided. Also, broken replies are not cached.

[Martin Kraemer] PR#2914

*) new `GprofDir' directive when compiled with -DGPROF, where gprof can

[Kurt Sussman <kls@best.com>] PR#2871

5 to 10 because there are some users out there who always have 5 to 8

release. So 15 should be now more than enough, even for them. (I never

needed more than 4 in my RewriteRules ;-)

[Ralf S. Engelschall]

the header lines. [Martin Kraemer]

*) Make sure the config.status file is not overridden when just

``configure --help'' is used. [Ralf S. Engelschall] PR#2844

*) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should

provide a way to trace API changes that add functionality but do

not create a compatibility issue for precompiled modules, etc.

See include/ap_mmn.h for more details. [Randy Terbush]

*) Fix suexec installation under `make install root=xxx' situation.

[Ralf S. Engelschall]

*) Extend the output of the -V switch to include the paths of all

compiled-in configuration files, if they were overridden at

compile time, for least astonishment of the user.

[Martin Kraemer]

*) When READing a request in ExtendedStatus mode, the "old"

vhost, request and client information is not displayed.

run-time configurable using the ExtendedStatus directive.

*) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)

cpu time attacks) in header parsing. Add ap_overlap_tables(),

a function which can be used to perform bulk update operations

on tables in a more efficient manner. [Dean Gaudet]

*) SECURITY: Added compile-time and configurable limits for

various aspects of reading a client request to avoid some simple

denial of service attacks, including limits on maximum request-line

size (LimitRequestLine), number of header fields (LimitRequestFields),

and size of any one header field (LimitRequestFieldsize). Also added

a configurable directive LimitRequestBody for limiting the size of the

request message body. [Roy Fielding]

STATUS not defined. [Jim Jagielski]

*) Fix a problem with the new OS/2 mutexes. [Brian Havard]

ap_scan_script_header_err_core() [Doug MacEachern]

*) The 'status' module will now show the process pid's and their

state even without full STATUS accounting. [Jim Jagielski]

*) Restore the client IP address to the error log messages, this

was lost during the transition from 1.2 to 1.3. Add a new

function ap_log_rerror() which takes a request_rec * and

formats it appropriately. [Dean Gaudet] PR#2661

*) Cure ap_cfg_getline() of its nasty habit of compressing internal

whitespace in input lines -- including within quoted strings.

stripped [Martin Kraemer]

*) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid

the ugly use of an env. variable and use command-line args for

alternate $PATH. Make more like advanced 'type's as well.

*) Clean up a warning in mod_proxy. [Ralf S. Engelschall]

*) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2

following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/

directory was renamed to src/os/os2/ for consistency.

[Brian Havard, Ralf S. Engelschall]

*) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO

files (here modules) against other DSO files (here shared libraries).

This is done by determining a subset of LIBS which can be safely used for

linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is

disabled for all platforms to avoid problems with this (experimental)

rule. But we provide it now for those people how ran into problems and

want to came out by forcing linking against DSOs.

the read_request error conditions of URI-too-long (414) and

malformed header fields (400). [Roy Fielding] PR#2646

*) Add support for the Max-Forwards: header line required by RFC2068 for

the TRACE method. This allows apache to TRACE along a chain of proxies

up to a predetermined depth. [Martin Kraemer]

*) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

[Martin Kraemer]

*) WIN32: Canonicalize ServerRoot before checking to see if it

is a valid directory. The failure to do this caused certain

ServerRoot settings (eg. "ServerRoot /apache") to be improperly

*) Global renaming of C header files to both get rid of conflicts with third

party packages and to again reach consistency:

1. conf.h -> ap_config.h

Backward compatibility files for conf.h and compat.h were created.

*) mod_mmap_static will no longer take action on requests unless at

least one "mmapfile" directive is present in the configuration.

This experimental module has to do some black magic to operate

inside the current API and thus creates side-effects for other

modules under some circumstances.

*) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via

TestCompile) instead of defining them manually in conf.h based on less

*) Improve performance of directory listings (mod_autoindex) by comparing

integer keys (last-modified and size) as integers rather than converting

them to strings first. Also use a set of explicit byte tests rather

than strcmp() to check for parent directory-ness of an entry. Oh, and

make sure the parent directory (if displayed) is *always* listed first

regardless of the sort key. Overall performance winnage should be good

in CPU time, instruction cache, and memory usage, particularly for large

directories. [Ken Coar]

*) Add a tiny but useful goody to APACI's configure script: The generation

of a config.status script (as GNU Autoconf does) which remembers the used

configure command and hence can be used to restore the configuration by

just re-running this script or for remembering the configuration between

releases.

[Ralf S. Engelschall]

*) Add httpd -t (test) option for running configuration syntax tests only.

If something is broken it complains and exits with a return code

non-equal to 0. This can be used manually by the user to check the Apache

configuration after editing and is also automatically used by apachectl

on (graceful) restart command to make sure Apache doesn't die on restarts

because of a configuration which is now broken since the last (re)start.

This way `apachectl restart' can be used inside cronjobs without having

to expect Apache to be falling down. Additionally the httpd -t can be run

via `apachectl configtest'.

ap_spawn_child_err_buff became ap_bspawn_child

spawn_child was obsoleted and moved to compat.h

[Brian Behlendorf]

*) Upgrade the child spawning code in mod_rewrite for the RewriteMap

programs: ap_spawn_child_err() is used and the Win32 case now uses

CreateProcess() instead of a low-level execl() (which caused problems in

the past under Win32).

[Ralf S. Engelschall]

*) A few cosmetics and trivial enhancements to APXS to make the

generated Makefile more user friendly. [Ralf S. Engelschall]

*) Proxy Fix: The proxy special failure routine ap_proxyerror()

was updated to use the normal apache error processing, thereby allowing

proxy errors to be treated by ErrorDocument's as well. For this

purpose, a new module-to-core communication variable "error-notes"

was introduced; the proxy (and possibly other modules) communicates

its error text using this variable. Its content is copied to a new

cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.

The old proxy special error routine ap_proxy_log_uerror()

was replaced by regular ap_log_error() calls, many messages were made

more informative.

[Martin Kraemer] PR#494, 1259

*) SECURITY: A possible buffer overflow in the ftp proxy was fixed.

[Martin Kraemer]

*) Transform the configure message "You need root privileges for suEXEC"

from a fatal error into a (more friendly) warning because the building

("make") of Apache we can allow, of course. Root privileges are needed

only for the installation step ("make install"). So make sure the

user is aware of this fact but let him proceed as long as he can.

[Ralf S. Engelschall] PR#2288

Changes with Apache 1.3b7

*) Make sure a MIME-type can be forced via a RewriteRule even when no

substitution takes place, for instance via the following rule:

``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

requested by users in the past to force a single script without a .cgi

[Ben Laurie] PR#2238

*) WIN32: CGIs could cause a hang (because of a deadlock in the standard C

instead of C file descriptors.

[Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607

*) The proxy cache would store an incorrect content-length in the cached

file copy after a cache update. That resulted in repeated fetching

of the original copy instead of using the cached copy.

[Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094

*) The Makefiles assumed that DSO files are build via $(LD). This

is broken for two reasons: First we never defined at least LD=ld

somewhere to make sure this works (it was silently assumed that most Make

provide a built-in LD definition - ARGL!) and second using the generic LD

variable is not the truth. Instead a special variable named LD_SHLIB is

reasonable because although "ld" is usually the default, the command for

building DSO files can be "libtool" or even "cc" on some systems.

[Ralf S. Engelschall]

*) Replace the AddVersionPlatform directive with ServerTokens which

provides for more control over the format of the Server:

header line. SERVER_SUBVERSION is no longer supported;

all module should use the ap_add_version_component()

API function instead. [Jim Jagielski]

*) Support for the NCR MP/RAS 3.0

[John Withers <withers@semi.kcsc.mwr.irs.gov>]

*) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was

not retrieved in src/Configure and thus was not useable.

[Ralf S. Engelschall]

*) Various Makefile consistency cleanups:

- make OSDIR also automatically be relative to src/ like INCDIR

- SUBDIRS is now generated in src/Makefile only and not in

Makefile.config because it is a local define for this location.

- remove BROKEN_BPRINTF_FLAGS because is it no longer used inside

any Makefile but make sure that at least the "-K inline" is kept in

CFLAGS for SCO 5.

- update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.

- updated the dependencies theirself

- removed not existing SHLIB variable from "clean" targets

- replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS

already exists and OBJS_PIC are also just plain objects and have not

directly to do with "shared" things. The only difference is that they

contain PIC. So OBJS_PIC is the more canonical name.

- Updated the Makefile-dependency lines for OBJS_PIC

- Removed the Makefile-dependency line in Configure to avoid double

definitions

- replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage

of xxx.lo as GNU libtool does with its PIC objects

- reduce local complexity in modules Makefile.tmpl by moving the last

existing target "depend" to the generation section in Configure, too.

- removed the historical $(SPACER) which was used in the past together

with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This

is no longer needed.

- force the build and run of the gen_xxx programs under main/ as the

first step before building the objects because it looks cleaner

[Ben Laurie]

*) WIN32: Don't force ISAPI headers to finish with \n.

[Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060

*) When opening "configuration" files (like httpd.conf, htaccess

and htpasswd), Apache will not allow them to be non-/dev/null

device files. This closes a DoS hole. At the same time,

we use ap_pfopen to open these files to handle timeouts.

[Jim Jagielski, Martin Kraemer]

*) Apache will now log the reason its httpd children exit if they exit

due to an unexpected signal. (It requires a new porting define,

SYS_SIGLIST, which if defined should point to a list of text

descriptions of the signals available. See PORTING.) [Dean Gaudet]

*) WIN32: chdir() doesn't make sense in a multithreaded environment

like WIN32. Before, Win32 CGI's could have had sporadic failures

if a chdir call from one thread was made between another chdir call

and a spawn in another thread. So, for now don't chdir for CGI scripts

in WIN32. The current CGI "spec" is unclear as to whether it's

necessary. Long-term fix is to either serialize the chdir/spawn combo

or use WIN32 native calls to spawn a process. This temp fix was

necessary to remove this as a showstopper for 1.3's release.

[Brian Behlendorf]

*) Cleanup the suEXEC support in APACI and make it more safe:

1. Add big fat hint in INSTALL about risks and to read the

htdocs/manual/suexec.html document before using the suexec-related

configure options.

2. Make sure the user has at least provided one --suexec-xxxx option

(specifies suEXEC parameters) in addition to --enable-suexec option.

If only --enable-suexec is given APACI stops with a hint to INSTALL

and htdocs/manual/suexec.html documents.

3. Provide two additional --suexec-xxxx options to make the suEXEC

configuration complete (especially for package maintainers who else

had to patch the source tree) by providing ways to configure minimal

UID/GID and safe PATH, too.

[Ralf S. Engelschall]

*) Cleanup of the `configure --shadow' process:

- make sure the configure script creates its temporary files in the

shadow tree to avoid conflicts with parallel configure runs

- removed unnecessary option "-r" from "rm" call for Makefiles

- make sure the configure scripts creates the shadow-wrapper Makefile

only when no shadow trees already exists

- make sure "make distclean" removes the shadow-wrapper Makefile but only

when no more shadow trees exists

- overhauled mkshadow.sh script: now its more IFS-safe and approx. twice

as fast (in the past it needed 70sec, now it runs just 38sec)

- make sure CVS does not complain about the created files

[Ralf S. Engelschall]

*) Added the ap_add_version_component() API routine and the

AddVersionPlatform core directive. The first allows modules to

declare themselves in the Server response header field value,

augmenting the SERVER_SUBVERSION define in the Configuration file

with run-time settings (more useful in a loadable-module environment).

AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"

into the server version string. [Ken Coar] PR#2056

*) Minor stability tweaks to avoid core dumps in ap_snprintf.

[Martin Kraemer]

*) Emit the "Accept-Range" header for the default handler.

[Brian Behlendorf] PR#1464

*) Add a note to httpd.conf-dist that apache will on some systems fail

to start when the Group # is set to a negative or large positive value.

[Martin Kraemer]

*) Make sure the module execution order is correct even when some modules

are loaded under runtime (`LoadModule') via the DSO mechanism:

1. The list of loaded modules is now a dynamically allocated one

and not the original statically list from modules.c

2. The loaded modules are now correctly setup by LoadModule for

later use by the AddModule command.

3. When the DSO mechanism for modules is used APACI's `install'

target now enables all created `LoadModule' lines per default because

this is both already expected by the user _and_ needed to avoid

confusion with the next point and reduces the Makefile.tmpl complexity

4. When the DSO mechanism for modules is used, APACI's `install'

target now additionally makes sure the module list is reconstructed

via a complete `ClearModuleList+AddModule...' entry.

5. The support tool `apxs' now also makes sure an AddModule command

is added in addition to the LoadModule command.

6. The modules.c generation was extended to now contain two

comments to make sure no one is confused by the confusing terminology

of loading/linking (we use load=link+load & link=activate instead of

the obvious load=activate & link=link :-( )

This way now there is no longer a difference under execution time between

statically and dynamically linked modules.

[Ralf S. Engelschall]

*) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the

Big Symbol Renaming. [Ralf S. Engelschall]

*) Add a comment to mod_example.c showing the format of a FLAG command

handler. [Ken Coar]

*) Standardized the time format in mod_status to match that of other

places in the code (e.g. DATE_GMT). PR#1551

*) Fix handling of %Z in timefmt strings for those platforms with no time

zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]

PR#754

*) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature

feature compatible with 'UseCanonicalName off' by changing

r->server->server_hostname to ap_get_server_name(). And I changed some

functions which use r->server->port to use ap_get_server_port() instead,

because if there's no Port directive in the config r->server->port is 0.

[Lars Eilebrecht]

*) get/set_module_config are trivial enough to be better off inline. Worth

1.5% performance boost. [Dean Gaudet]

*) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c

when ensuring 'x' is at least 30-chars big. [Jim Jagielski,

Brian Behlendorf]

*) [BS2000 security] BS2000 needs an extra authentication to initialize

the task environment to the unprivileged User id. Otherwise CGI scripts

would have a way to gain super user access. [Martin Kraemer]

*) Fix debug log messages for BS2000/OSD: instead of logging the whole

absolute path, only log base name of logging source as is done

in unix. [Martin Kraemer]

*) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in

the encoding type from the Accept-Encoding header (if it's there)

and use it in the response, as that's probably what it'll be expecting.

[Ronald.Tschalaer@psi.ch]

*) Fix to mod_alias: translate_alias_redir is dealing with

a URI, not a filename, so the check for drive letters for win32

and emx is not necessary. [Dean Gaudet]

*) WIN32: Allow .cmd as an executable extension.

[Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146

*) Make Apache header files, and some variables, C++ friendly.

[Michael Anderson's <mka@redes.int.com.mx>]

*) Child processes can now "signal" (by exiting with a status

of APEXIT_CHILDFATAL) the parent process to abort and

shutdown the server if the error in the child process was

fatal enough. [Jim Jagielski]

*) mod_autoindex's find_itme() was sensitive to MIME type case.

[Jim Jagielski] PR#2112

*) Make sure the referer_log and agent_log entries in the default httpd.conf

file are also adjusted for the actual relative installation paths.

[Ralf S. Engelschall] PR#2175

*) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]

*) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]

PR#1558

*) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.

Additionally the checks for finding the vendor DSO library were moved

from mod_so.c to Configure because first it needs $PLAT etc. and second

mod_so already uses an abstraction layer and does not fiddle with the

vendor functions itself.

[Jens-Uwe Mager, Ralf S. Engelschall]

*) PORT: Some optimization defines for NetBSD

[Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165

*) PORT: Dynamic Shared Object (DSO) support for NetBSD.

[Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158

*) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older

AIX variants should work fine, too. Even AIX 3.x should work). This is

accomplished by using the free DSO emulation code from Jens-Uwe Mager

which we put into a os/unix/os-dso-aix.c file.

[Ralf S. Engelschall]

*) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply

that we should use NET_SIZE_T == int but the include files force size_t.

[Ralf S. Engelschall]

*) Fix two bugs in select() handling in http_main.c.

[Roy Fielding]

*) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO

is unset (as it is in situations like timeouts) where it is unclear

whether errno is set or not. [Martin Kraemer]

*) Just having APACI's localstatedir is too general and not enough for most

of the systems. 1.3b6 again required manual APACI patches by package

maintainers from RedHat and FreeBSD because for their filesystem layout a

little bit more flexibility in configuring the paths is needed. Hence we

provide three additional configure options (--runtimedir, --logfiledir,

--proxycachedir) which now can be used for more granular adjustments if

--localstatedir is not enough to fit the particular needs. As a nice

side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.

[Ralf S. Engelschall]

*) Make the install root for "make install" in APACI's Makefile overrideable

by package authors. This way we are even more friendly to package

maintainers (especially Debian and RedHat) who build for the real prefix

via "configure --prefix=/<real>" but use a different local prefix via

"make root=/tmp/apache install" for rolling the package without bristling

the target location on their system.

[Ralf S. Engelschall]

*) Workaround sed limitations in APACI's configure script by now

substituting in chunks of 50 commands (because for instance HPUX's vendor

sed has a limit of max. 98 commands)

[Ralf S. Engelschall] PR#2136

*) Adding SOCKS5 support and fixing existing SOCKS4 support.

[Ralf S. Engelschall] PR#2140

*) Manually fix some symbols which were not renamed to prefix ap_ in the BIG

RENAMING process because they are defined as pre-processor macros instead

of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd

[Ralf S. Engelschall]

*) Workaround braindead AWK's when generating ap_config.h: The split() and

substr() functions cannot be nested under vendor AWK from Solaris 2.6.

[Ralf S. Engelschall] PR#2139

*) Various bugfixes and cleanups for the APACI configure script:

o fix IFS handling for _nested_ situation

o fix Perl interpreter search: take first one found instead of last one

o fix DSO consistency check

o print error messages to stderr instead of stdout

o add install-quiet for --shadow situation to Makefile stub

o reduce complexity by avoiding sed-hacks for rule and module list loops

[Ralf S. Engelschall]

*) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114

*) Make sure the input field separator (IFS) shell variable is explicitly

initialized correctly before _every_ `for' loop and also restored after

the loops. [Ralf S. Engelschall]

*) Make sure that "make install" doesn't overwrite the `mime.types' and

`magic' files from an existing Apache installation. Because people often

customize these for own MIME and content types.

[Ralf S. Engelschall]

*) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x

[Peter Galbavy, Ralf S. Engelschall] PR#2109

*) Fix the path to the ScoreBoardFile in the install-config target, too.

[Ralf S. Engelschall] PR#2105

*) Let "configure" clear out the users parameters (provided as shell

variables) to avoid side-effects in "src/Configure" when the user

exported them (which is not needed, but some users do it).

[Ralf S. Engelschall] PR#2101

*) Provide backward compatibility from some old src/Configuration.tmpl

parameter names to the canonical Autoconf-style shell variable names. For

instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now

but a hint message is displayed. [Ralf S. Engelschall]

*) Make sure that "make install" doesn't overwrite the DocumentRoot and

CGI scripts from an existing Apache installation.

[Ralf S. Engelschall, Jim Jagielski] PR#2084

*) Make `configure --compat' more "compatible" by first

let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and

second by making sure the "avoid-bristling-suffix" /apache is not

appended to sysconfdir, datadir, localstatedir and includedir when

--compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

*) NeXT required strdup() in support/logresolve.c

[Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082

*) AIX required sys/select.h in support/ab.c

[Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081

*) Fix the path to the MimeMagicFile in the install-config target, too.

[Ralf S. Engelschall] PR#2089

*) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]

*) If you start apache with the -S command line option it will dump

out the parsed vhost settings. This is useful for folks trying

to figure out what is wrong with their vhost configuration.

(Other dumps may be added in the future.) [Dean Gaudet]

*) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,

ap_snprintf, and ap_psprintf). See include/ap.h for docs.

[Dean Gaudet]

*) Because /usr/local/apache is the default prefix the ``configure

--compat'' option no longer has to set prefix, again. This way the

--compat option honors a leading --prefix option. [Lars Eilebrecht]

*) PORT: Cast the first argument of dlopen() in ap_os_dso_load()

to `char *' under OSF1 and FreeBSD 2.x where it is defined this way

to avoid "discard const" warnings. [Ralf S. Engelschall]

*) If a specific handler is set for a file yet the request still

ends up being handled by the default handler, log an error

message before handling it. This catches things such as trying

to use SSIs without mod_include enabled. [Marc Slemko]

*) Fix error logging for the startup case where ap_log_error() still uses

stderr as the target. Now the default log level is honored here, too.

[Ralf S. Engelschall]

*) PORT: Make sure some AWK's don't fail in src/Configure with "string too

long" errors when generating the MODULES entry for src/Makefile

[Ben Hyde, Ralf S. Engelschall]

*) Make sure src/Configure doesn't complain about the old directory

/usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]

Changes with Apache 1.3b6

*) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]

*) Adding DSO support for the HP/UX platform by emulating the dlopen-style

interface via the similar but proprietary HP/UX shl_xxx-style system

calls. [Ralf S. Engelschall]

*) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made

APACI Makefile.tmpl "install" target more robust for sensible UnixWare

Make. [Ralf S. Engelschall]

*) ++++ THE BIG SYMBOL RENAMING ++++

To avoid symbol clashes with third-party code compiled into the server,

we globally applied the prefix "ap_" to the following classes of

functions:

- Apache provided general functions (e.g., ap_cpystrn)

- Public API functions (e.g., palloc, bgets)

- Private functions which we can't make static (because of

cross-object usage) but should be (e.g., new_connection)

For backward source compatibility a new header file named compat.h was

created which provides defines for the old symbol names and can be used

by third-party module authors.

[The Apache Group]

*) Added dynamic shared object (DSO) support for SVR4-derivates: The

problem under SVR4 is that there is no command flag to force the linker

to export the global symbols of the httpd executable therewith they are

available to the DSO's. Instead of problematic hacks like creating a

dummy.so file (containing dummy references to all global symbols) the

httpd binary is linked against, we use a clean trick stolen from Perl 5:

Placing the Apache core code itself into a DSO library named libhttpd.so.

This way the global symbols _HAVE_ to be exported and thus are available

to any manually loaded DSO's under runtime. To reduce the impact to the

user to null we go even further and create a stub httpd executable which

automatically keeps track of the DSO library loading itself and thus

hides the complete mechanism from the user. Although the generation of

this DSO library is automatically triggered for platforms which

essentially need it (mostly all SVR4-derivates) it can be also enabled

manually via the Rule SHARED_CORE. This can be interesting in the future

where we perhaps exploit this libhttpd.so mechanism for providing nifty

features like graceful upgrades, or whatever.

[Ralf S. Engelschall, Martin Kraemer]

*) Build the libraries before building the rest of the tools. [Ben Hyde]

*) Add "distclean" target to src/-Makefiles to provide "make distclean" also

inside the src subtree (i.e. for non-APACI users). Following GNU Makefile

conventions while "clean" removes only stuff created by "all" targets,

"distclean" additionally removes the stuff from the configuration

process. This way "make distclean" (hence the name) provides a fresh

source tree as it was for distribution.

[Ralf S. Engelschall]

*) Allow top-level (APACI) Makefile to break on build errors

the same way the src/ subtree Makefiles breaks on them by replacing the

initial APACI sed-subdir-display-kludge with a more clean

variable-passing-solution: variable SDP can optionally hold the subdir

prefix which is consistently used for displaying the subdir movement.

This way even the top-level Makefile can stop correctly on errors as the

user expects. [Ralf S. Engelschall]

*) Fixed ordering of argument checks for RewriteBase directive.

[Todd Eigenschink <eigenstr@mixi.net>] PR#2045

*) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of

indicating that a module is being compiled for dynamic loading. Also

remove #define IS_MODULE from modules and add SHARED_MODULE define

to the mak/dsp files. [Alexei Kosut]

*) Reduce logging level of "normal" warning messages to APLOG_INFO,

since we are now logging APLOG_WARNING by default. [Roy Fielding]

*) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]

*) Add documentation file and src/Configuration.tmpl entry for the

experimental mod_mmap_static module. Because although it is and marked as

an experimental one it is distributed and thus should be documented and

prepared for configuration the same way as all others modules.

[Ralf S. Engelschall]

*) Add query (-q) option to apxs support tool to be able to manually query

specific settings from apxs. This is needed for instance when you

manually want to access Apache's header files and you need to assemble

the -I option. Now you can do -I`apxs -q INCLUDEDIR`.

[Ralf S. Engelschall]

*) Now src/Configure uses a fallback strategy for the shared object support

on platforms where no explicit information is available: If a Perl

installation exists we ask it about its shared object support and if it's

the dlopen-style one we shamelessly guess the compiler and linker flags

for creating shared objects from Perls knowledge. Of course, the user is

warning about what we are doing and informed that he should send us

the guessed flags when they work. [Ralf S. Engelschall]

*) Provide APACI --without-support option to be able to disable the build

and installation of the support tools from the src/support/ area.

Although its useful to have these installed per default we should provide

a way to compile and install without them for backward-compatibility.

[Ralf S. Engelschall]

*) Add of the new APache eXtenSion (apxs) support tool for building and

installing modules into an _already installed_ Apache package through the

dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that

this approach actually doesn't need the Apache source tree. The

(APACI-installed) server package is enough, because this now includes the

Apache C header files (PREFIX/include) and the new APXS tool

(SBINDIR/apxs). The intend is to provide a handy tool for third-party

module authors to build their Apache modules _OUTSIDE_ the Apache source

tree while avoiding them to fiddle around with the totally platform

dependend way of compiling DSO files. The tool supports all ranges of

modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3

which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can

on-the-fly generate a minimalistic Makefile and sample module for the

first step to provide both a quick success event and to demonstrate the

APXS mechanism to module authors. [Ralf S. Engelschall]

*) Fix core dumps in use of CONNECT in proxy.

[Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942

*) Modify the log directives in httpd.conf-dist files to use CustomLog

so that users have examples of how CustomLog can be used.

[Lars Eilebrecht]

*) Add the new Apache Autoconf-style Interface (APACI) for the top-level of

the Apache distribution tree. Until Apache 1.3 there was no real

out-of-the-box batch-capable build and installation procedure for the

complete Apache package. This is now provided by a top-level "configure"

script and a corresponding top-level "Makefile.tmpl" file. The goal is

to provide a GNU Autoconf-style frontend which is capable to both drive

the old src/Configure stuff in batch and additionally installs the

package with a GNU-conforming directory layout. Any options from the old

configuration scheme are available plus a lot of new options for flexibly

customizing Apache. [Ralf S. Engelschall]

*) The floating point ap_snprintf code wasn't threadsafe.

Had to remove the HAVE_CVT macro in order to do threadsafe

calling of the ?cvt() floating point routines. [Dean Gaudet]

*) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962

*) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler

[Jim Jagielski] PR#1901

*) BUG: Configure was using TCC and CC inconsistently. Make sure

Configure knows which CC we are using. [Jim Jagielski]

*) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"

was defined in a parent directory. [Lars Eilebrecht]

*) API: ap_snprintf() code mutated into ap_vformatter(), which is

a generic printf-style routine that can call arbitrary output

routines. Use this to replace http_bprintf.c. Add new routines

psprintf(), pvsprintf() which allocate the exact amount of memory

required for a string from a pool. Use psprintf() to clean up

various bits of code which used ap_snprintf()/pstrdup().

[Dean Gaudet]

*) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because

ap_snprintf() has different semantics and formatting codes than

snprintf(). [Dean Gaudet]

*) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This

is necessary on at least Solaris where the /etc/rc?.d scripts

are run with these signals ignored, and "SIG_IGN" settings are

maintained across exec().

[Rein Tollevik <reint@sys.sol.no>] PR#2009

*) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was

used instead of lstat() and thus this flag didn't work as expected.

[Rein Tollevik <reint@sys.sol.no>] PR#2010

*) Fix the proxy pass-through feature of mod_rewrite for the case of

existing QUERY_STRING now that mod_proxy was recently changed because of

the new URL parsing stuff. [Ralf S. Engelschall]

*) A few changes to scoreboard definitions which helps gcc generate

better code. [Dean Gaudet]

*) ANSI C doesn't guarantee that "int foo : 2" in a structure will

be a signed bitfield. So mark a few bitfields as signed to

ensure correct code. [Dean Gaudet]

*) The default for HostnameLookups was changed to Off, but there

was a problem and it wasn't taking effect. [Dean Gaudet]

*) PORT: Clean up undefined signals on some platforms (SCO, BeOS).

[Dean Gaudet]

*) After a SIGHUP the listening sockets in the parent weren't

properly marked for closure on fork().

[J�rgen Keil <jk@tools.de>] PR#2000

*) Allow %2F in two situations: 1) it is in the query part of the URI,

therefore not exposed to %2F -> '/' translations and 2) the request

is a proxy request, so we're not dealing with a local resource anyway.

Without this, the proxy would fail to work for any URL's with

%2f in them (occurs quite often in

http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]

*) Protect against FD_SETSIZE mismatches. [Dean Gaudet]

*) Make the shared object compilation command more portable by avoiding

the direct combination of `-c' & `-o' which is not honored by some

compilers like UnixWare's cc. [Ralf S. Engelschall]

*) WIN32: the proxy was creating filenames missing the last four

characters. While this normally doesn't stop anything from

working, it can result in extra collisions.

[Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890

*) Now mod_proxy uses the response string (in addition to the response status

code) from the already used FTP SIZE command to setup the Content-Length

header if available. [Ralf S. Engelschall] PR#1183

*) Reanimated the (still undocumented) proxy receive buffer size directive:

Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old

name was really too generic, added documentation for this directive to

the mod_proxy.html and corrected the hyperlink to it in the

new_features_1.3.html document. [Ralf S. Engelschall] PR#1348

*) Fix a bug in the src/helpers/fp2rp script and make it a little bit

faster [Martin Kraemer]

*) Make Configure die when you give it an unknown command switch.

[Ben Hyde]

*) Add five new and fresh manpages for the support programs: dbmmanage.1,

suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date

and per default compiled support programs have manual pages - just to

document our stuff a little bit more and to be able to do really

Unix-like installations ;-) [Ralf S. Engelschall]

*) Major cleanups to the Configure script to make it and its generated

Makefiles again readable and maintainable: add SRCDIR option, removed

INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of

generated sections, consequently added Makefile headers with inheritance

information, added subdir movement messages for easier following where

the build process currently stays (more verbose then standard Make, less

verbose than GNU make), same style to comments in the Configure script,

added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]

*) Add the new ApacheBench program "ab" to src/support/: This is derived

from the ZeusBench benchmarking program and can be used to determine the

response performance of an Apache installation. This version is

officially licensed with Zeus Technology, Ltd. See the license agreement

statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.

[Ralf S. Engelschall]

*) API: Various core functions that are definately not part of the API

have been made static, and a few have been marked API_EXPORT. Still

more have been marked CORE_EXPORT and are not intended for general

use by modules. [Doug MacEachern, Dean Gaudet]

*) mod_proxy was not clearing the Proxy-Connection header from

requests; now it does. This did not violate any spec, however

causes poor interactions when you are talking to remote proxies.

[Marc Slemko] PR#1741

*) Various cleanups to the command line interface and manual pages.

[Ralf S. Engelschall]

*) cfg_getline() was not properly handling lines that did not end

with a line termination character. [Marc Slemko] PR#1869, 1909

*) Performance tweak to mod_log_config. [Dmitry Khrustalev]

*) Clean up some undocumented behavior of mod_setenvif related to

"merging" two SetEnvIf directives when they match the same header

and regex. Document that mod_setenvif will perform comparisons in

the order they appear in the config file. Optimize mod_setenvif by

doing more work at config time rather than at runtime.

[Dean Gaudet]

*) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's

to allow for modules to overrule them and to reduce redefinition

warnings [Jim Jagielski]

*) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.

[Jim Jagielski]

*) Making the hard-coded cross-module function call mime_find_ct() (from

mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type

checking is really called even for proxy requests except for URLs with

HTTP schemes (because there we can optimize by not running the type

checking hooks due to the fact that the proxy gets the MIME Content-type

from the remote host later). This change cleans up mod_mime by removing

the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and

especially unbundles mod_proxy and mod_mime. This way they both now can

be compiled as shared objects and are no longer tied together.

[Ralf S. Engelschall]

*) util.c cleanup and speedup. [Dean Gaudet]

*) API: Clarification, pstrndup() will always copy n bytes of the source

and NUL terminate at the (n+1)st byte. [Dean Gaudet]

*) Mark module command_rec and handler_rec structures const so that they

end up in the read-only data section (and are friendlier to systems

that don't do optimistic memory allocation on fork()). [Dean Gaudet]

*) Add check to the "Port" directive to make sure the specified

port is in the appropriate range. [Ben Hyde]

*) Performance improvements to invoke_handler().

[Dmitry Khrustalev <dima@bog.msu.su>]

*) Added support for building shared objects even for library-style modules

(which are built from more than one object file). This now provides the

ability to build mod_proxy as a shared object module. Additionally

modules like mod_example are now also supported for shared object

building because the generated Makefiles now no longer assume there is at

least one statically linked module. [Ralf S. Engelschall]

*) API: Clarify usage of content_type, handler, content_encoding,

content_language and content_languages fields in request_rec. They

must always be lowercased; and the strings pointed to shouldn't

be modified (you must copy them to modify them). Fix a few bugs

related to this. [Dean Gaudet]

*) API: Clarification: except for RAW_ARGS, all command handlers can

treat the char * parameters as permanent, and modifiable. There

is no need to pstrdup() them. Clean up some needless pstrdup().

[Dean Gaudet]

*) Now mod_so keeps track of which module shared objects with which names

are loaded and thus avoids multiple loading and unloading and irritating

error_log messages. [Ralf S. Engelschall]

*) Prior to the existence of mod_setenv it was necessary to tweak the TZ

environment variable in the apache core. But that tweaking interferes

with mod_setenv. So don't tweak if the user has specified an explicit

TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

*) rputs() did not calculate r->sent_bodyct properly.

[Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900

*) The CGI spec says that REMOTE_HOST should be set to the remote hosts's

name, or left unset if this value is unavailable. Apache was setting

it to the IP address when unavailable.

[Tony Finch <fanf@demon.net>] PR#1925

*) Various improvements to the configuration and build support for compiling

modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and

OSF1 support with GCC and vendor compilers was added. This way shared

object support is now provided out-of-the-box for FreeBSD, Linux,

Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

[Ralf S. Engelschall]

*) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"

scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD

and USE_OS2_SCOREBOARD. [Dean Gaudet]

*) Fix one more special locking problem for RewriteMap programs in

mod_rewrite: According to the documentation of flock(), "Locks are on

files, not file descriptors. That is, file descriptors duplicated

through dup(2) or fork(2) do not result in multiple instances of a lock,

but rather multiple references to a single lock. If a process holding a

lock on a file forks and the child explicitly unlocks the file, the

parent will lose its lock.". To overcome this we have to make sure the

RewriteLock file is opened _AFTER_ the childs were spawned which is now

the case by opening it in the child_init instead of the module_init API

hook. [Ralf S. Engelschall] PR#1029

*) Change to Location and LocationMatch semantics. LocationMatch no

longer lets a single slash match multiple adjacent slashes in the

URL. This change is for consistency with RewriteRule and

AliasMatch. Multiple slashes have meaning in URLs that they do

not have in (some) filesystems. Location on the other hand can

be considered a shorthand for a more complicated regex, and it

does match multiple slashes with a single slash -- which is

also consistent with the Alias directive.

*) Fix bug with mod_mime_magic causing certain files, including files

of length 0, to result in no response from the server.

[Dean Gaudet]

*) The Configure script now generates src/include/ap_config.h which

contains the set of defines used when Apache is compiled on a platform.

This file can then be included by external modules before including

any Apache header files in case they are being built separately from

Apache. Along with this change, a couple of minor changes were

made to make Apache's #defines coexist peacefully with any autoconf

defines an external module might have. [Rasmus Lerdorf]

*) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist

but without any RewriteXXXXX directives. Here mod_rewrite is given no

chance by the API to initialize its per-server configuration and thus

receives the wrong one from the main server. This is now avoided by

remembering the server together with the config structure while

configuring and later assuming there is no config when we see a

difference between the remembered server and the one calling us.

[Ralf S. Engelschall] PR#1790

*) Fixed the DBM RewriteMap support for mod_rewrite: First the support now

is automatically disabled under configure time when the dbm_xxx functions

are not available. Second, two heavy source code errors in the DBM

support code were fixed. This makes DBM RewriteMap's usable again after

a long time of brokenness. [Ralf S. Engelschall] PR#1696

*) Now all configuration files support Unix-style line-continuation via

the trailing backslash ("\") character. This enables us to write down

complex or just very long directives in a more readable way. The

backslash character has to be really the last character before the

newline and it has not been prefixed by another (escaping) backslash.

*) WIN32: Preserve trailing slash in canonical path (and hence

*) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable

depending on the rev of Solaris and what mixture of modules

are in use. So it has been disabled, and Solaris is back to

using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with

USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed

up static content only servers. Or it may fail unpredictably.

[Dean Gaudet] PR#1779, 1854, 1904

*) mod_test_util_uri.c created which tests the logic in util_uri.c.

[Dean Gaudet]

*) API: Rewrite of absoluteURI handling, and in particular how

absoluteURIs match vhosts. Unless a request is a proxy request, a

"http://host" url is treated as if a similar "Host:" header had been

supplied. This change was made to support future HTTP/1.x protocols

which may require clients to send absoluteURIs for all requests.

In order to achieve this change subtle changes were made to the API. In a

request_rec, r->hostlen has been removed. r->unparsed_uri now exists so

that the unmodified uri can be retrieved easily. r->proxyreq is not set

by the core, modules must set it during the post_read_request or

translate_names phase.

Plus changes to the virtualhost test suite for absoluteURI testing.

This fixes several bugs with the proxy proxying requests to vhosts

managed by the same httpd.

[Dean Gaudet]

*) API: Cleanup of code in http_vhost.c, and remove vhost matching

code from mod_rewrite. The vhost matching is now performed by a

globally available function matches_request_vhost(). [Dean Gaudet]

*) Add the `%a' construct to LogFormat and CustomLog to log the client IP

*) API: A new source module main/util_uri.c; It contains a routine

parse_uri_components() and friends which breaks a URI into its component

parts. These parts are stored in a uri_components structure called

parsed_uri within each request_rec, and are available to all modules.

Additionally, an unparse routine is supplied which re-assembles the URI

components back to an URI, optionally hiding the username:password@ part

from ftp proxy requests, and other useful routines. Within the structure,

you find on a ready-for-use basis:

scheme; /* scheme ("http"/"ftp"/...) */

hostinfo; /* combined [user[:password]@]host[:port] */

user; /* user name, as in http://user:passwd@host:port/ */

password; /* password, as in http://user:passwd@host:port/ */

hostname; /* hostname from URI (or from Host: header) */

port_str; /* port string (integer representation is in "port") */

path; /* the request path (or "/" if only scheme://host was given) */

query; /* Everything after a '?' in the path, if present */

fragment; /* Trailing "#fragment" string, if present */

This is meant to serve as the platform for *BIG* savings in

code complexity for the proxy module (and maybe the vhost logic).

[Martin Kraemer]

*) Make all possible meta-construct expansions ($N, %N, %{NAME} and

${map:key}) available for all location where a string is created in

mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the

possible expansions are consequently usable at all string creation

locations. [Ralf S. Engelschall]

*) Fix initialization of RewriteLogLevel (default now is 0 as documented

and not 1) and the per-virtual-server merging of directives. Now all

directives except `RewriteEngine' and `RewriteOption' are either

completely overridden (default) or completely inherited (when

`RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

*) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'

type but with a special post-processing for the looked-up value: It

parses it into alternatives according to `|' chars and then only one

particular alternative is chosen randomly (this is an essential

functionality needed for balancing between backend-servers when using

Apache as a Reverse Proxy. The looked up value here is a list of

servers). Second, `int' with the built-in maps named `tolower' and

`toupper' which can be used to map URL parts to a fixed case (this is an

essential feature to fix the case of server names when doing mass

virtual-hosting with the help of mod_rewrite instead of using

<VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

Jay Soffian <jay@cimedia.com>] PR#1631

*) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.

This directive lets Apache adjust the URL in Location-headers on HTTP

redirect responses sent by the remote server. This way the virtually

mapped area is no longer left on redirects and thus by-passed which is

especially essential when running Apache as a reverse proxy.

*) MiNT port update. [Jan Paul Schmidt]

*) HTTP/1.1 requires x-gzip and gzip encodings be treated

equivalent, similarly for x-compress and compress. Apache

preserves the encoding the client requests (for example if

it requests x-gzip, then Apache will respond with x-gzip

in the Content-Encoding header).

get_server_port().

PR#315, 459, 485, 1433

*) Yet another rearrangement of the source tree.. now all the common

header files are in the src/include directory. The -Imain -Iap

references in Makefiles have been changed to the simpler -Iinclude

instead. In addition to simplifying the build a little bit, this

also makes it clear when a module is referencing something in a

other than kosher manner (e.g., the proxy including mod_mime.h).

Module-private header files (the proxy, mod_mime, the regex library,

and mod_rewrite) have not been moved to src/include; nor have

the OS-abstraction files. [Ken Coar]

*) Fix a bug where r->hostname didn't have the :port stripped

*) Tweaked the headers_out table size, and the subprocess_env

table size guess in rename_original_environment(). Added

MAKE_TABLE_PROFILE which can help discover make_table()

[Dean Gaudet]

*) Options and AllowOverride weren't properly merging in the main

server setting inside vhosts (only an issue when you have no

<Directory> or other section containing an Options that affects

a request). Options +foo or -foo in the main_server wouldn't

affect the main_server's lookup defaults. [Dean Gaudet]

*) Variable 'cwd' was being used pointlessly before being set.

[Ken Coar] PR#1738

*) r->allowed handling cleaned up in the standard modules.

[Dean Gaudet]

*) Some case-sensitivity issues cleaned up to be consistent with

RFC2068. [Dean Gaudet]

*) SIGURG doesn't exist everywhere.

[Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]

*) mod_unique_id was erroneously generating a second unique id when

an internal redirect occured. Such redirects occur, for example,

when processing a DirectoryIndex match. [Dean Gaudet]

*) API: table_add, table_merge, and table_set include implicit pstrdup()

of the key and value. But in many cases this is not required

because the key/value is a constant, or the value has been built

by pstrcat() or other similar means. New routines table_addn,

table_mergen, and table_setn have been added to the API, these

routines do not pstrdup() their arguments. The core code and

standard modules were changed to take advantage of these routines.

The resulting server is up to 20% faster in some situations.

Note that it is easy to get code subtly wrong if you pass a key/value

which is in a pool other than the pool of the table. The only

safe thing to do is to pass key/values which are in the pool of

the table, or in one of the ancestors of the pool of the table.

i.e. if the table is part of a subrequest, a value from the main

request's pool is OK since the subrequest pool is a sub_pool of the

main request's pool (and therefore has a lifespan at most as long as

the main pool). There is debugging code which can detect improper

usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

[Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]

*) More mod_mime_magic cleanup: fewer syscalls; should handle "files"

which don't exist on disk more gracefully; handles vhosts properly.

Update documentation to reflect the code -- if there's no

MimeMagicFile directive then the module is not enabled.

[Dean Gaudet]

*) PORT: Some older *nix dialects cannot automatically start scripts

which begin with a #! interpreter line (the shell starts the scripts

appropriately on these platforms). Apache now supports starting of

"hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

[Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)

taken from tcsh]

*) API: "typedef array_header table" removed from alloc.h, folks should

have been writing to use table as if it were an opaque type, but even

some standard modules got this wrong. By changing the definition

to "typedef struct table table" module authors will receive compile

time warnings that they're doing the wrong thing. This change

facilitates future changes with more sophisticated table

structures. Specifically, module authors should be using table_elts()

to get access to an array_header * for the table. [Dean Gaudet]

*) API: Renamed new_connection() to avoid namespace collision with LDAP

library routines. [Ken Coar, Rasmus Lerdorf]

*) WIN32: mod_speling is now available on the Win32 platform.

[Marc Slemko]

*) For clarity the following compile time definition was changed:

SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT

Also, for example, HAVE_MMAP would mean to use mmap() scoreboards

and not be a general notice that the OS has mmap(). Now the

HAVE_MMAP/SHMGET #defines strictly are informational that the

OS has that method of shared memory; the type to use for

the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD

and USE_SHMGET_SCOREBOARD). This allows outside modules to

determine if shared memory is available and allows Apache

to determine the best method to use for the scoreboard.

[Jim Jagielski]

*) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,

*) Create LARGE_WRITE_THRESHOLD define which determines how many

doing a writev() to assemble multiple buffers in one system

mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller

strings in some cases. The result would be extra effort

setting up writev(), and in many cases extra effort building

chunks. The default is 31, it can be overriden at compile

time. [Dean Gaudet]

*) Move the gid switching code into the child so that log files

and pid files are opened with the root gid.

[Gregory A Lundberg <lundberg@vr.net>]

*) WIN32: Check for binaries by looking for the executable header

instead of counting control characters.

[Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340

*) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c

so the functionality is available to applications other than the

server itself (like the src/support tools). [Ken Coar]

*) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of

the libap consolidation work. [Ken Coar]

*) ap_snprintf() with a len of 0 behaved like sprintf(). This is not

useful, and isn't what the standards require. Now it returns 0

and writes nothing. [Dean Gaudet]

*) When an error occurs in fcntl() locking suggest the user look up

the docs for LockFile. [Dean Gaudet]

*) Eliminate some dead code from writev_it_all().

[Igor Tatarinov <tatarino@prairie.NoDak.edu>]

*) mod_autoindex had an fread() without checking the result code.

It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

(note the missing closing paren) properly. [Dean Gaudet]

*) It appears the "257th byte" bug (see

htdocs/manual/misc/known_client_problems.html#257th-byte) can happen

at the 256th byte as well. Fixed. [Dean Gaudet]

*) PORT: Fix mod_mime_magic under OS/2, no support for block devices.

[Brian Havard]

*) Fix memory corruption caused by allocating auth usernames in the

wrong pool. [Dean Gaudet] PR#1500

*) Fix an off-by-1, and an unterminated string error in

mod_mime_magic. [Dean Gaudet]

*) Fix a potential SEGV problem in mod_negotiation when dealing

with type-maps. [Dean Gaudet]

*) Better glibc support under Linux. [Dean Gaudet] PR#1542

[Ben Laurie] PR#1101

*) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523

*) proxy_ftp: the directory listings generated by the proxy ftp module

now have a title in which the path components are clickable and allow

quick navigation to the clicked-on directory on the currently listed

ftp server. This also fixes a bug where the ".." directory links would

sometimes refer to the wrong directory. [Martin Kraemer]

Changes with Apache 1.3b3

*) WIN32: Work around brain-damaged spawn calls that can't deal

with spaces and slashes. [Ben Laurie]

*) WIN32: Fix the code so CGIs can use socket calls on Windows.

The problem was that certain undocumented environment variables

needed for sockets to work under Win32 were not being passed.

[Frank Faubert <frank@sane.com>]

*) Add a "-V" command line flag to the httpd binary. This

flag shows some of the defines that Apache was compiled with.

It is useful for debugging purposes. [Martin Kraemer]

*) Start separating the ap_*() routines into their own library, so they

can be used by items in src/support among other things.

[Ken Coar] PR#512, 905, 1252, 1308

*) Give a more informative error when no AuthType is set.

[Lars Eilebrecht]

*) Remove strtoul() use from mod_proxy because it isn't available

on all platforms. [Marc Slemko] PR#1214

*) WIN32: Some Win32 systems terminated all responses after 16 kB.

This turns out to be a bug in Winsock - select() doesn't always

return the correct status. [Ben Laurie]

*) Directives owned by http_core can now use the new check_cmd_context()

routine to ensure that they're not being used within a container

(e.g., <Directory>) where they're invalid. [Martin Kraemer]

*) PORT: Recent changes made it necessary to add explicit prototype

for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]

*) It was necessary to distinguish between resources which are

allocated in the parent, for cleanup in the parent, and resources

which are allocated in each child, for cleanup in each child.

A new pool was created which is passed to the module child_init

and child_exit functions; modules are free to register per-child

cleanups there. This fixes a bug with reliable piped logs.

[Dean Gaudet]

*) mod_autoindex wasn't displaying the ReadmeName file at the bottom

unless it was also doing FancyIndexes, but it displayed the

HeaderName file at the top under all circumstances. It now shows

the ReadmeName file for simple indices, too, as it should.

[Ken Coar] PR#1373

*) http_core was mmap()ing even in cases where it wasn't going to

read the file. [Ben Hyde <bhyde@gensym.com>]

*) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:

Now the rewriting engine (the heart of mod_rewrite) is organized more

straight-forward, first time well documented and reduced to the really

essential parts. All redundant cases were stripped off and processing now

is the same for both per-server and per-directory context with only a

minimum difference (the prefix stripping in per-dir context). As a

side-effect some subtle restrictions and two recently discovered problems

are gone: Wrong escaping of QUERY_STRING on redirects in per-directory

context and restrictions on the substitution URL on redirects.

Additionally some minor source cleanups were done.

[Ralf S. Engelschall]

*) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals

documentation, examples, explanations and caveats. They live in a new

subdirectory htdocs/manual/vhost/. [Lars Eilebrecht <sfx@unix-ag.org>]

*) If ap_slack fails to allocate above the low slack line it's a good

indication that further problems will occur; it's a better indication

than many external libraries give us when we actually run out of

descriptors. So report it to the user once per restart.

[Dean Gaudet] PR#1181

*) Change mod_include and mod_autoindex to use Y2K-safe date formats

[Lars Eilebrecht] PR#870

*) Fix a byte ordering problem in mod_access which prevented

the old-style syntax (i.e. "a.b.c." to match a class C)

from working properly. [Dean Gaudet] PR#1248, 1328, 1384

*) When a configuration parse complained about a bad directive,

the logger would use whatever (unrelated) value was in errno.

breaking on some systems. [Bhaba R.Misra <system@vt.edu>] PR#1368

*) Solaris >= 2.5 was totally broken due to a mess up using pthread

*) PORT: All ports which don't otherwise define DEF_WANTHSREGEX will

get Spencer regex by default. This is to avoid having to

discover bugs in operating system libraries. [Dean Gaudet]

splits up a combined access log into separate files based on the

name of the virtual host (listed first in the log records by "%v").

[Ken Coar]

Changes with Apache 1.3b2 (there is no 1.3b1)

*) TestCompile was not passing $LIBS [Dean Gaudet]

*) Makefile.tmpl was not using $CFLAGS in the link phase.

[Martin Kraemer]

*) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a

rudimentary memory debugger which can be used on live servers with

low impact -- it sets all allocated and freed memory bytes to 0xa5.

Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()

and free() for each object. This is far more expensive and should

only be used for testing with tools such as Electric Fence and

Purify. See main/alloc.c for more details. [Dean Gaudet]

*) Configure uses a sh trap and didn't set its exitcode properly.

[Dean Gaudet] PR#1159

*) Yet another vhost revamp. Add the NameVirtualHost directive which

explicitly lists the ip:port pairs that are to be used for name-vhosts.

From a given ip:port, regardless what the Host: header is, you can

only reach the vhosts defined on that ip:port. The precedence of

vhosts was reversed to match other precedences in the config --

the earlier vhosts override the later vhosts. All vhost matching was

moved into http_vhost.[ch]. [Dean Gaudet]

*) ap_inline can be used to force inlining. GNUC __attribute__() can

be used for whatever reason is appropriate (i.e. format() warnings

for printf style functions). Both are enabled only with

gcc >= 2.7.x (so that we have fewer support issues with older

versions). [Dean Gaudet]

*) Fix support for Proxy Authentication (we were testing the response

status too early). [Marc Slemko]

*) CoreDumpDirectory directive directs where the core file is

written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are

received. [Marc Slemko, Dean Gaudet]

*) PORT: Support for Atari MINT.

[Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]

*) When booting, apache will now detach itself from stdin, stdout,

and stderr. stderr will not be detached until after the config

files have been read so you will be able to see initial error

messages. After that all errors are logged in the error_log.

This makes it more convenient to start apache via rsh, ssh,

or crontabs. [Dean Gaudet] PR#523

*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.

Also removed the auto-generated link to www.apache.org that was the

source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]

*) send_fb would not detect aborted connections in some situations.

[Dean Gaudet]

*) mod_include would use uninitialized data when parsing certain

expressions involving && and ||. [Brian Slesinsky] PR#1139

*) mod_imap should only handle GET methods. [Jay Bloodworth]

*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]

*) mod_autoindex improperly counted &escapes; as more than one

character in the description. It also improperly truncated

descriptions that were exactly the maximum length.

[Martin Kraemer]

*) RedirectMatch was not properly escaping the result (PR#1155). Also

"RedirectMatch /advertiser/(.*) $1" is now permitted.

[Dean Gaudet]

*) mod_include now uses symbolic names to check for request success

and return HTTP errors, and correctly handles all types of

redirections (previously it only did temporary redirect correctly).

[Ken Coar, Roy Fielding]

*) mod_userdir was modifying r->finfo in cases where it wasn't setting

r->filename. Since those two are meant to be in sync with each other

this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

*) PORT: Support Unisys SVR4, whose uname returns mostly useless data.

["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]

*) Inetd mode (which is buggy) uses timeouts without having setup the

jmpbuffer. [Dean Gaudet] PR#1064

*) Work around problem under Linux where a child will start looping

reporting a select error over and over.

[Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588

*) Fixed error in proxy_util.c when looping through multiple host IP

addresses. [Lars Eilebrecht] PR#974

*) If BUFFERED_LOGS is defined then mod_log_config will do atomic

buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)

bytes before writing, but it will never split a log entry across a

buffer boundary. [Dean Gaudet]

*) API: the short_score record has been split into two pieces, one which

the parent writes on, and one which the child writes on. As part of

this change the get_scoreboard_info() function was removed, and

scoreboard_image was exported. This change fixes a race condition

in file based scoreboard systems, and speeds up changes involving the

scoreboard in earlier 1.3 development. [Dean Gaudet]

*) API: New register_other_child() API (see http_main.h) which allows

modules to register children with the parent for maintenance. It

is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]

*) API: New piped_log API (see http_log.h) which implements piped logs,

and will use register_other_child to implement reliable piped logs

when it is available. The reliable piped logs part can be disabled

by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped

logs is only available on Unix. [Dean Gaudet]

*) API: set_last_modified() broken into set_last_modified(), set_etag(), and

meets_conditions(). This allows conditional HTTP selection to be

handled separately from the storing of the header fields, and provides

the ability for CGIs to set their own ETags for conditional checking.

[Ken Coar, Roy Fielding] PR#895

*) Changes to mod_log_config to allow naming of format strings.

Format nicknames are defined with "LogFormat fmt nickname", and can

be used with "LogFormat nickname" and "CustomLog logtarget nickname".

[Ken Coar]

*) New module, "mod_speling", which can help find files even when

the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]

*) API: New function child_terminate() triggers the child process to

exit, while allowing the child finish what it needs to for the

current request first.

[Doug MacEachern, Alexei Kosut]

*) Windows now defaults to using full status reports with mod_status.

[Alexei Kosut] PR #1094

*) *Really* disable all mod_rewrite operations if the engine is off.

Some things (like RewriteMaps) were checked/performed even if they

weren't supposed to be. [Ken Coar] PR #991

*) Implement a new timer scheme which eliminates the need to call alarm() all

the time. Instead a counter in the scoreboard for each child is used to

show when the child has made forward progress. The parent samples this

counter every scoreboard maintenance cycle, and issues SIGALRM if no

progress has been made in the timeout period. This reduces the static

request best-case syscall count to 22 from 29. This scheme is only

used by systems with memory-based scoreboards. [Dean Gaudet]

*) The proxy now properly handles CONNECT requests which are sent

to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024

*) A script called apachectl has been added to the support

directory. This script allows you to do things such as

"apachectl start" and "apachectl restart" from the command

line. [Marc Slemko]

*) Modules and core routines are now put into libraries, which

simplifies the link line tremendously (among other advantages).

[Paul Sutton]

*) Some of the MD5 names defined in Apache have been renamed to have

an `ap_' prefix to avoid conflicts with routines supplied by

external libraries. [Ken Coar]

*) Removal of mod_auth_msql.c from the distribution. There are many

other options for databases today. Rather than offer one option,

offer none at this time. mod_auth_msql and other SQL database

authentication modules can be found at the Apache Module Registry.

http://modules.apache.org/ It would be nice to offer a generic

mod_auth_sql option in the near future.

*) PORT: BeOS support added [Alexei Kosut]

*) Configure no longer accepts the -make option, since it creates

Makefile on the fly based on Makefile.tmpl and Configuration.

*) Apache now gracefully shuts down when it receives a SIGTERM, instead

of forcibly killing off all its processes and exiting without

cleaning up. [Alexei Kosut]

*) API: A new field in the request_rec, r->mtime, has been added to

avoid gratuitous parsing of date strings. It is intended to hold

the last-modified date of the resource (if applicable). An

update_mtime() routine has also been added to advance it if

appropriate. [Roy Fielding, Ken Coar]

*) SECURITY: If a htaccess file can not be read due to bad permissions,

deny access to the directory with a HTTP_FORBIDDEN. The previous

behavior was to ignore the htaccess file if it could not be read.

This change may make some setups with unreadable htaccess files

stop working. [Marc Slemko] PR#817

*) Add aplog_error() providing a mechanism to define levels of

verbosity to the server error logging. This addition also provides

the ability to log errors using syslogd. Error logging is configurable

on a per-server basis using the LogLevel directive. Conversion

of log_*() in progress. [Randy Terbush]

*) Further enhance aplog_error() to not log filename, line number, and

errno information when it isn't applicable. [Ken Coar, Dean Gaudet]

*) WIN32: Canonicalise filenames under Win32. Short filenames are

converted to long ones. Backslashes are converted to forward

slashes. Case is converted to lower. Parts of URLs that do not

correspond to files are left completely alone. [Ben Laurie]

*) PORT: 2 new OSs added to the list of ports:

Encore's UMAX V: Arieh Markel <amarkel@encore.com>

Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>

*) Add the server version (SERVER_VERSION macro) to the "server

configured and running" entry in the error_log. Also build an

object file at link-time that contains the current time

(SERVER_BUILT global const char[]), and include that in the

message. [Ken Coar]

*) Set r->headers_out when sending responses from the proxy.

This fixes things such as the logging of headers sent from

the proxy. [Marc Slemko] PR#659

*) support/httpd_monitor is no longer distributed because the

scoreboard should not be file based if at all possible. Use

mod_status to see current server snapshot.

*) (set_file_slot): New function, allowing auth directives to be

independent of the server root, so the server documents can be

moved to a different directory or machine more easily.

[David J. MacKenzie]

*) If no TransferLog is given explicitly, decline

to log. This supports coexistence with other logging modules,

such as the custom one that UUNET uses. [David J. MacKenzie]

*) Check for titles in server-parsed HTML files.

Ignore leading newlines and returns in titles. The old behavior

of replacing a newline after <title> with a space causes the

title to be misaligned in the listing. [David J. MacKenzie]

*) Change mod_cern_meta to be configurable on a per-directory basis.

[David J. MacKenzie]

*) Add 'Include' directive to allow inclusion of configuration

files within configuration files. [Randy Terbush]

*) Proxy errors on connect() are logged to the error_log (nothing

new); now they include the IP address and port that failed

(*that's* new). [Ken Coar, Marc Slemko] PR#352

*) Various architectures now define USE_MMAP_FILES which causes

the server to use mmap() for static files. There are two

compile-time tunables MMAP_THRESHOLD (minimum number of bytes

required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum

number of bytes written in one cycle from a single mmap()d object,

default 32768). [Dean Gaudet]

*) API: Added post_read_request API phase which is run right after reading

the request from a client, or right after an internal redirect. It is

useful for modules setting environment variables that depend only on

the headers/contents of the request. It does not run during subrequests

because subrequests inherit pretty much everything from the main

request. [Dean Gaudet]

*) Added mod_unique_id which is used to generate a unique identifier for

each hit, available in the environment variable UNIQUE_ID.

[Dean Gaudet]

*) init_modules is now called after the error logs have been opened. This

allows modules to emit information messages into the error logs.

[Dean Gaudet]

*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging

information for case where proxy module is not available. [Marc Slemko]

*) PORT: Apache has need for mutexes to serialize its children around

accept. In prior versions either fcntl file locking or flock file

locking were used. The method is chosen by the definition of

USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),

and FLOCK for flock(). New options have been added:

- SYSVSEM to use System V style semaphores

- PTHREAD to use POSIX threads (appears to work on Solaris only)

- USLOCK to use IRIX uslock

Based on timing various techniques, the following changes were made

to the defaults:

- Linux 2.x uses flock instead of fcntl

- Solaris 2.x uses pthreads

- IRIX uses SysV semaphores -- however multiprocessor IRIX boxes

work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT

[Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,

Martijn Koster <m.koster@pobox.com>]

*) PORT: The semantics of accept/select make it very desirable to use

mutexes to serialize accept when multiple Listens are in use. But

in the case where only a single socket is open it is sometimes

redundant to serialize accept(). Not all unixes do a good job with

potentially dozens of children blocked on accept() on the same

socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and

the server will avoid serialization when listening on only one socket,

and use serialization when listening on multiple sockets.

[Dean Gaudet] PR#467

*) Configure changes: TestLib replaced by TestCompile, which has

some additional capability (such as doing a sanity check of

the compiler and flags selected); the version of Solaris is now

available via the #define value of SOLARIS2; IRIX n32bit libs

now supported and selectable by new Configuration Rule: IRIXN32;

We no longer default to -O2 optimization. [Jim Jagielski]

*) Updated Configure: Configuration now uses AddModule to specify

module source or binary file location, relative to src directory.

Modules can be dropped into modules/extra, or in their own

directory, and modules can come with a Makefile or Configure can

create one. Modules can add compiler or library information to

generated Makefiles. [Paul Sutton]

*) Source core re-organisation: distributed modules are now in

modules/standard. All other source code is in main. OS-specific

code is in os/{unix,emx,win32} directories. [Paul Sutton]

*) mod_browser has been removed, since it's replaced by mod_setenvif.

[Ken Coar]

*) Fix another long-standing bug in sub_req_lookup_file where it would

happily skip past access checks on subdirectories looked up with

relative paths. (It's used by mod_dir, mod_negotiation,

and mod_include.) [Dean Gaudet]

*) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where

N is the number of <Directory> sections, and M is the number of

components in the filename of an object.

To achieve this optimization the following config changes were made:

- Wildcards (* and ?, not the regex forms) in <Directory>s,

<Files>s, and <Location>s now treat a slash as a special

character. For example "/home/*/public_html" previously would

match "/home/a/andrew/public_html", now it only matches things

like "/home/bob/public_html". This mimics /bin/sh behaviour.

- It's possible now to use [] wildcarding in <Directory>, <Files>

or <Location>.

- Regex <Directory>s are applied after all non-regex <Directory>s.

[Dean Gaudet]

*) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files

and corrupted paths. [Dean Gaudet]

*) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:

First the grouped parts of RewriteRule pattern matches (parenthesis!) can

be accessed now via backreferences $1..$9 in RewriteConds test-against

strings in addition to RewriteRules subst string. Second the grouped

parts of RewriteCond pattern matches (parenthesis!) can be accessed now

via backreferences %1..%9 both in following RewriteCond test-against

strings and RewriteRules subst string. This provides maximum flexibility

through the use of backreferences.

Additionally the rewriting engine was cleaned up by putting common

code to the new expand_backrefs_inbuffer() function.

[Ralf S. Engelschall]

*) When merging the main server's <Directory> and <Location> sections into

a vhost, put the main server's first and the vhost's second. Otherwise

the vhost can't override the main server. [Dean Gaudet] PR#717

*) The <Directory> code would merge and re-merge the same section after

a match was found, possibly causing problems with some modules.

[Dean Gaudet]

*) ip-based vhosts are stored and queried using a hashing function, which

has been shown to improve performance on servers with many ip-vhosts.

Some other changes had to be made to accommodate this:

- the * address for vhosts now behaves like _default_

- the matching process now is:

- match an ip-vhost directly via hash (possibly matches main

server)

- if that fails, just pretend it matched the main server

- if so far only the main server has been matched, perform

name-based lookups (ServerName, ServerAlias, ServerPath)

*only on name-based vhosts*

- if they fail, look for _default_ vhosts

[Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]

*) dbmmanage overhaul:

- merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new

- tie() to AnyDBM_File which will use one of DB_File, NDBM_File or

GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)

- provide better seed for rand

- prompt for password as per getpass(3) (turn off echo, read from

/dev/tty, etc.)

- use "newstyle" crypt based on $Config{osname} ($^O)

- will not add a user if already in database, use new `update' command

instead

- added `check' command to check a users' password

- added `import' command to convert existing password text-files or

dbm files exported with `view'

- more descriptive usage, general cleanup, 'use strict' clean, etc.

[Doug MacEachern]

*) Added psocket() which is a pool form of socket(), various places within

the proxy weren't properly blocking alarms while registering the cleanup

for its sockets. bclose() now uses pclose() and pclosesocket(). There

was a bug where the client socket was being close()d twice due a still

registered cleanup. [Dean Gaudet]

*) A few cleanups were made to reduce time(), getpid(), and signal() calls.

[Dean Gaudet]

*) PORT: AIX >= 4.2 requires -lm due to libc changes.

[Jason Venner <jason@idiom.com>] PR#667

*) Enable ``=""'' for RewriteCond directives to match against

the empty string. This is the preferred way instead of ``^$''.

[Ralf S. Engelschall]

*) Fixed an infinite loop in mod_imap for references above the server root

[Dean Gaudet] PR#748

*) mod_proxy now has a ReceiveBufferSize directive, similar to

SendBufferSize, so that the TCP window can be set appropriately

for LFNs. [Phillip A. Prindeville]

*) mod_browser has been replaced by the more general mod_setenvif

(courtesy of Paul Sutton). BrowserMatch* directives are still

available, but are now joined by SetEnvIf*, UnSetEnvIf*, and

UnSetEnvIfZero directives. [Ken Coar]

*) "HostnameLookups double" forces double-reverse DNS to succeed in

order for remote_host to be set (for logging, or for the env var

REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.

[Dean Gaudet]

*) mod_access overhaul:

- Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)

and cidr syntax (i.e. 10.1.0.0/16). PR#762

- Critical path was sped up by pre-computing a few things at config time.

- The undocumented syntax "allow user-agents" was removed,

the replacement is "allow from env=foobar" combined with mod_browser.

- When used with hostnames it now forces a double-reverse lookup

no matter what the directory settings are. This double-reverse

doesn't affect any of the other routines that use the remote

hostname. In particular it's still passed to CGIs and the log

without the double-reverse check. Related PR#860.

[Dean Gaudet]

*) When a large bwrite() occurs (larger than the internal buffer size),

while there is already something in the buffer, apache will combine

the large write and the buffer into a single writev(). (This is

in anticipation of using mmap() for reading files.)

[Dean Gaudet]

*) In obscure cases where a partial socket write occurred while chunking,

Apache would omit the chunk header/footer on the next block. Cleaned

up other bugs/inconsistencies in error conditions in buff.c. Fixed

a bug where a long pause in DNS lookups could cause the last packet

of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]

*) API: Added child_exit function to module structure. This is called

once per "heavy-weight process" just before a server child exit()'s

e.g. when max_requests_per_child is reached, etc.

[Doug MacEachern, Dean Gaudet]

*) mod_include cleanup showed that handle_else was being used to handle

endif. It didn't cause problems, but it was cleaned up too.

[Howard Fear]

*) mod_cern_meta would attempt to find meta files for the directory itself

in some cases, but not in others. It now avoids it in all cases.

[Dean Gaudet]

*) mod_mime_magic would core dump if there was a decompression error.

[Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904

*) PORT: some variants of DGUX require -lsocket -lnsl

[Alexander L Jones <alex@systems-options.co.uk>] PR#732

*) mod_autoindex now allows sorting of FancyIndexed directory listings

by the various fields (name, size, et cetera), either in ascending

or descending order. Just click on the column header. [Ken Coar]

*) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit

CPUs like the Alpha. Apache still stores ints in pointers, but that's

the relatively safe direction. [Dean Gaudet] PR#344

*) PORT: QNX mmap() support for faster/more reliable scoreboard handling.

[Igor N Kovalenko <infoh@mail.wplus.net>] PR#683

*) child_main avoids an unneeded call to select() when there is only one

listening socket. [Dean Gaudet]

*) In the event that the server is starved for idle servers it will

spawn 1, then 2, then 4, ..., then 32 servers each second,

doubling each second. It'll also give a warning in the errorlog

since the most common reason for this is a poor StartServers

setting. The define MAX_SPAWN_RATE can be used to raise/lower

the maximum. [Dean Gaudet]

*) Apache now provides an effectively unbuffered connection for

CGI scripts. This means that data will be sent to the client

as soon as the CGI pauses or stops output; previously, Apache would

buffer the output up to a fixed buffer size before sending, which

could result in the user viewing an empty page until the CGI finished

or output a complete buffer. It is no longer necessary to use an

"nph-" CGI to get unbuffered output. Given that most CGIs are written

in a language that by default does buffering (e.g. perl) this

shouldn't have a detrimental effect on performance.

"nph-" CGIs, which formerly provided a direct socket to the client

without any server post-processing, were not fully compatible with

HTTP/1.1 or SSL support. As such they would have had to implement

the transport details, such as encryption or chunking, in order

to work properly in certain situations. Now, the only difference

between nph and non-nph scripts is "non-parsed headers".

[Dean Gaudet, Sameer Parekh, Roy Fielding]

*) If a BUFF is switched from buffered to unbuffered reading the first

bread() will return whatever remained in the buffer prior to the

switch. [Dean Gaudet]

Changes with Apache 1.3a1

*) Added another Configure helper script: TestLib. It determines

if a specified library exists. [Jim Jagielski]

*) PORT: Allow for use of n32bit libraries under IRIX 6.x

[derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]

PR#721

*) PORT: Some architectures use size_t for various lengths in network

functions such as accept(), and getsockname(). The definition

NET_SIZE_T is used to control this. [Dean Gaudet]

*) PORT: Linux: Attempt to detect glibc based systems and include crypt.h

and -lcrypt. Test for various db libraries (dbm, ndbm, db) when

mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]

*) PORT: QNX doesn't have initgroups() which support/suexec.c uses.

[Igor N Kovalenko <infoh@mail.wplus.net>]

*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to

begin with. "nokeepalive" now works for HTTP/1.1 clients. Added

"downgrade-1.0" which causes Apache to pretend it received a 1.0.

[Dean Gaudet] related PR#875

*) API: Correct child_init() slot declaration from int to void, to

match the init() declaration. Update mod_example to use the new

hook. [Ken Coar]

*) added transport handle slot (t_handle) to the BUFF structure

[Doug MacEachern]

*) get_client_block() returns wrong length if policy is

REQUEST_CHUNKED_DECHUNK.

[Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815

*) Support the image map format of FrontPage. For example:

rect /url.hrm 10 20 30 40

["Chris O'Byrne" <obyrne@iol.ie>] PR#807

*) PORT: -lresolv and -lsocks were in the wrong order for Solaris.

["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846

*) AddModuleInfo directive for mod_info which allows you to annotate

the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]

*) Added NoProxy directive to avoid using ProxyRemote for selected

addresses. Added ProxyDomain directive to cause unqualified

names to be qualified by redirection.

[Martin Kraemer <Martin.Kraemer@mch.sni.de>]

*) Support Proxy Authentication, and don't pass the Proxy-Authorize

header to the remote host in the proxy. [Sameer Parekh and

Wallace]

*) Upgraded mod_rewrite from 3.0.6+ to latest officially available version

3.0.9. This upgrade includes: fixed deadlooping on rewriting to same

URLs, fixed rewritelog(), fixed forced response code handling on

redirects from within .htaccess files, disabled pipe locking under

braindead SunOS 4.1.x, allow env variables to be set even on rules with

no substitution, bugfixed situations where HostnameLookups is off, made

mod_rewrite more thread-safe for NT port and fixed problem when creating

an empty query string via "xxx?".

This update also removes the copyright of Ralf S. Engelschall,

i.e. now mod_rewrite no longer has a shared copyright. Instead is is

exclusively copyrighted by the Apache Group now. This happened because

the author now has gifted mod_rewrite exclusively to the Apache Group and

no longer maintains an external version.

[Ralf S. Engelschall]

*) API: Added child_init function to module structure. This is called

once per "heavy-weight process" before any requests are handled.

See http_config.h for more details. [Dean Gaudet]

*) Anonymous_LogEmail was logging on each subrequest.

[Dean Gaudet] PR#421, 868

*) API: Added is_initial_req() which tests if the request being

processed is the initial request, or a subrequest.

[Doug MacEachern]

*) Extended SSI (mod_include) now handles additional relops for

string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41

*) Configure fixed to correctly propagate user-selected options and

settings (such as CC and OPTIM) to Makefiles other than

src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834

*) IndexOptions SuppressHTMLPreamble now causes the actual HTML of

directory indices to start with the contents of the HeaderName file

if there is one. If there isn't one, the behaviour is unchanged.

[Ken Coar, Roy Fielding, Andrey A. Chernov]

*) WIN32: Modules can now be dynamically loaded DLLs using the

LoadModule/LoadFile directives. Note that module DLLs must be

compiled with the multithreaded DLL version of the runtime library.

[Alexei Kosut and Ben Laurie]

*) Automatic indexing removed from mod_dir and placed into mod_autoindex.

This allows the admin to completely remove automatic indexing

from the server, while still supporting the basic functions of

trailing-slash redirects and DirectoryIndex files. Note that if

you're carrying over an old Configuration file and you use directory

indexing then you'll want to add:

Module autoindex_module mod_autoindex.o

before mod_dir in your Configuration. [Dean Gaudet]

*) popendir/pclosedir created to properly protect directory scanning.

[Dean Gaudet] PR#525

*) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,

giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>

and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...

[Alexei Kosut]

*) The AccessFileName directive can now take more than one filename.

["Lou D. Langholtz" <ldl@usi.utah.edu>]

*) The new mod_mime_magic can be used to "magically" determine the type

of a file if the extension is unknown. Based on the unix file(1)

command. [Ian Kluft <ikluft@cisco.com>]

*) We now determine and display the time spent processing a

request if desired. [Jim Jagielski]

*) mod_status: PID field of "dead" child slots no longer displays

main httpd process's PID. [Jim Jagielski]

*) Makefile.nt added - to build all the bits from the command line:

nmake -f Makefile.nt

Doesn't yet work properly. [Ben Laurie]

*) Default text of 404 error is now "Not Found" rather than the

potentially misleading "File Not Found". [Ken Coar]

*) CONFIG: "HostnameLookups" now defaults to off because it is far better

for the net if we require people that actually need this data to

enable it. [Linus Torvalds]

*) directory_walk() is an expensive function, keep a little more state to

avoid needless string counting. Add two new functions make_dirstr_parent

and make_dirstr_prefix which replace all existing uses of make_dirstr.

The new functions are a little less general than make_dirstr, but

work more efficiently (less memory, less string counting).

[Dean Gaudet]

*) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed

to LDFLAGS) to avoid complications with lex rules in make files.

[Dean Gaudet] PR#372

*) run_method optimized to avoid needless scanning over NULLs in the

module list. [Dean Gaudet]

*) Revamp of (unix) scoreboard management code such that it avoids

unnecessary traversals of the scoreboard on each hit. This is

particularly important for high volume sites with a large

HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),

and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in

httpd.h. [Dean Gaudet]

*) In configurations using multiple Listen statements it was possible for

busy sockets to starve other sockets of service. [Dean Gaudet]

*) Added hook so standalone_main can be replaced at compile time

(define STANDALONE_MAIN)

[Doug MacEachern]

*) Lowest-level read/write functions in buff.c will be replaced with

the SFIO library calls sfread/sfwrite if B_SFIO is defined at

compile time. The default sfio discipline will behave as apache

would without sfio compiled in.

[Doug MacEachern]

*) Enhance UserDir directive (mod_userdir) to accept a list of

usernames for the 'disable' keyword, and add 'enable user...' to

selectively *en*able userdirs if they're globally disabled.

[Ken Coar]

*) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache

will work with Netscape dbm files. (dbmmanage will probably not

work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444

*) Add a ListenBacklog directive to control the backlog parameter

passed to listen(). Also change the default to 511 from 512.

[Marc Slemko]

*) API: A new handler response DONE which informs apache that the

request has been handled and it can finish off quickly, similar to

how it handles errors. [Rob Hartill]

*) Turn off chunked encoding after sending terminating chunk/footer

so that we can't do it twice by accident. [Roy Fielding]

*) mod_expire also issues Cache-Control: max-age headers.

[Rob Hartill]

*) API: Added kill_only_once option for free_proc_chain so that it won't

aggressively try to kill off specific children. For fastcgi.

[Stanley Gambarin <gambarin@OpenMarket.com>]

*) mod_auth deals with extra ':' delimited fields. [Marc Slemko]

*) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.

When used together, these cause mod_dir to emit HEIGHT and WIDTH

attributes in the FancyIndexing IMG tags. [Ken Coar]

*) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]

*) PORT: Added Windows NT support

[Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]

Changes with Apache 1.2.6

*) mod_include when using XBitHack Full would send ETags in addition to

sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.

[Dean Gaudet] PR#1133

*) SECURITY: When a client connects to a particular port/addr, and

gives a Host: header ensure that the virtual host requested can

actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]

*) Support virtual hosts with wildcard port and/or multiple ports

properly. [Ed Korthof <ed@organic.com>]

*) Fixed some case-sensitivity issues according to RFC2068.

[Dean Gaudet]

*) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,

and mod_include.c. [Dean Gaudet]

*) Variable 'cwd' was being used pointlessly before being set.

[Ken Coar] PR#1738

*) SIGURG doesn't exist on all platforms.

[Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]

*) When an error occurs during a POST, or other operation with a

request body, the body has to be read from the net before allowing

a keepalive session to continue. [Roy Fielding] PR#1399

*) When an error occurs in fcntl() locking suggest the user look up

the docs for LockFile. [Dean Gaudet]

*) table_set() and table_unset() did not deal correctly with

multiple occurrences of the same key. [Stephen Scheck

<sscheck@infonex.net>, Ben Laurie] PR#1604

*) send_fd_length() did not calculate total_bytes_sent properly in error

cases. [Ben Reser <breser@regnow.com>] PR#1366

*) r->connection->user was allocated in the wrong pool causing corruption

in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500

*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.

Also removed the auto-generated link to www.apache.org that was the

source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]

*) Multiple "close" tokens may have been set in the "Connection"

header, not an error, but a waste.

[Ronald.Tschalaer@psi.ch] PR#1683

*) "basic" and "digest" auth tokens should be tested case-insensitive.

[Ronald.Tschalaer@psi.ch] PR#1599, PR#1666

*) It appears the "257th byte" bug (see

htdocs/manual/misc/known_client_problems.html#257th-byte) can happen

at the 256th byte as well. Fixed. [Dean Gaudet]

*) mod_rewrite would not handle %3f properly in some situations.

[Ralf Engelschall]

*) Apache could generate improperly chunked HTTP/1.1 responses when

the bputc() or rputc() functions were used by modules (such as

mod_include). [Dean Gaudet]

*) #ifdef wrap a few #defines in httpd.h to make life easier on

some ports. [Ralf Engelschall]

*) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]

*) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]

*) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]

Changes with Apache 1.2.5

*) SECURITY: Fix a possible buffer overflow in logresolve. This is

only an issue on systems without a MAXDNAME define or where

the resolver returns domain names longer than MAXDNAME. [Marc Slemko]

*) Fix an improper length in an ap_snprintf call in proxy_date_canon().

[Marc Slemko]

*) Fix core dump in the ftp proxy when reading incorrectly formatted

directory listings. [Marc Slemko]

*) SECURITY: Fix possible minor buffer overflow in the proxy cache.

[Marc Slemko]

*) SECURITY: Eliminate possible buffer overflow in cfg_getline, which

is used to read various types of files such as htaccess and

htpasswd files. [Marc Slemko]

*) SECURITY: Ensure that the buffer returned by ht_time is always

properly null terminated. [Marc Slemko]

*) SECURITY: General mod_include cleanup, including fixing several

possible buffer overflows and a possible infinite loop. This cleanup

was done against 1.3 code and then backported to 1.2, the result

is a large difference (due to indentation cleanup in 1.3 code).

Users interested in seeing a smaller set of relevant differences

should consider comparing against src/modules/standard/mod_include.c

from the 1.3b3 release. Non-indentation changes to mod_include

between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]

*) SECURITY: Numerous changes to mod_imap in a general cleanup

including fixing a possible buffer overflow. This cleanup also

was done with 1.3 code as a basis, see the the previous note

about mod_include. [Dean Gaudet]

*) SECURITY: If a htaccess file can not be read due to bad

permissions, deny access to the directory with a HTTP_FORBIDDEN.

The previous behavior was to ignore the htaccess file if it could not

be read. This change may make some setups with unreadable

htaccess files stop working. PR#817 [Marc Slemko]

*) SECURITY: no2slash() was O(n^2) in the length of the input.

Make it O(n). This inefficiency could be used to mount a denial

of service attack against the Apache server. Thanks to

Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

this. [Dean Gaudet]

*) mod_include used uninitialized data for some uses of && and ||.

[Brian Slesinsky <bslesins@wired.com>] PR#1139

*) mod_imap should decline all non-GET methods.

[Jay Bloodworth <jay@pathways.sde.state.sc.us>]

*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]

*) mod_userdir was modifying r->finfo in cases where it wasn't setting

r->filename. Since those two are meant to be in sync with each other

this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

*) mod_include did not properly handle all possible redirects from sub-

requests. [Ken Coar]

*) Inetd mode (which is buggy) uses timeouts without having setup the

jmpbuffer. [Dean Gaudet] PR#1064

*) Work around problem under Linux where a child will start looping

reporting a select error over and over.

[Rick Franchuk <rickf@transpect.net>] PR#1107

Changes with Apache 1.2.4

*) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy

always making requests with the full-URI instead of just the URI path.

[Marc Slemko, Roy Fielding]

*) Add -lm for AIX versions >= 4.2 to allow Apache to link properly

on this platform. [Marc Slemko]

Changes with Apache 1.2.3

*) The request to a remote proxy was mangled if it was generated as the

result of a ProxyPass directive. URL schemes other than http:// were not

supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

PR#812 [Lars Eilebrecht]

*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging

information for case where proxy module is not available. [Marc Slemko]

*) Force proxy to always respond as HTTP/1.0, which it was failing to

do for errors and cached responses. [Roy Fielding]

*) PORT: Improved support for ConvexOS 11. [Jeff Venters]

Changes with Apache 1.2.2 [not released]

*) Fixed another long-standing bug in sub_req_lookup_file where it would

happily skip past access checks on subdirectories looked up with relative

paths. (It's used by mod_dir, mod_negotiation, and mod_include.)

[Dean Gaudet]

*) Add lockfile name to error message printed out when

USE_FLOCK_SERIALIZED_ACCEPT is defined.

[Marc Slemko]

*) Enhanced the chunking and error handling inside the buffer functions.

[Dean Gaudet, Roy Fielding]

*) When merging the main server's <Directory> and <Location> sections into

a vhost, put the main server's first and the vhost's second. Otherwise

the vhost can't override the main server. [Dean Gaudet] PR#717

*) The <Directory> code would merge and re-merge the same section after

a match was found, possibly causing problems with some modules.

[Dean Gaudet]

*) Fixed an infinite loop in mod_imap for references above the server root.

[Dean Gaudet] PR#748

*) mod_include cleanup showed that handle_else was being used to handle

endif. It didn't cause problems, but it was cleaned up too.

[Howard Fear]

*) Last official synchronization of mod_rewrite with author version (because

mod_rewrite is now directly developed by the author at the Apache Group):

o added diff between mod_rewrite 3.0.6+ and 3.0.9

minus WIN32/NT stuff, but plus copyright removement.

In detail:

- workaround for detecting infinite rewriting loops

- fixed setting of env vars when "-" is used as subst string

- fixed forced response code on redirects (PR#777)

- fixed cases where r->args is ""

- kludge to disable locking on pipes under braindead SunOS

- fix for rewritelog in cases where remote hostname is unknown

- fixed totally damaged request_rec walk-back loop

o remove static from local data and add static to global ones.

o replaced ugly proxy finding stuff by simple

find_linked_module("mod_proxy") call.

o added missing negation char on rewritelog()

o fixed a few comment typos

[Ralf S. Engelschall]

*) Anonymous_LogEmail was logging on each subrequest.

[Dean Gaudet] PR#421, PR#868

*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to

begin with. "nokeepalive" now works for HTTP/1.1 clients. Added

"downgrade-1.0" which causes Apache to pretend it received a 1.0.

Additionally mod_browser now triggers during translate_name to workaround

a deficiency in the header_parse phase.

[Dean Gaudet] PR#875

*) get_client_block() returns wrong length if policy is

REQUEST_CHUNKED_DECHUNK.

[Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815

*) Properly treat <files> container like other containers in mod_info.

[Marc Slemko] PR#848

*) The proxy didn't treat the "Host:" keyword of the host header as case-

insensitive. The proxy would corrupt the first line of a response from

an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814

*) mod_include would log some bogus values occasionally.

[Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797

*) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP

under Solaris 2.x (up through 2.5.1). It has been fixed.

[Dean Gaudet] PR#832

*) API: In HTTP/1.1, whether or not a request message contains a body

is independent of the request method and based solely on the presence

of a Content-Length or Transfer-Encoding. Therefore, our default

handlers need to be prepared to read a body even if they don't know

what to do with it; otherwise, the body would be mistaken for the

next request on a persistent connection. discard_request_body()

has been added to take care of that. [Roy Fielding] PR#378

*) API: Symbol APACHE_RELEASE provides a numeric form of the Apache

release version number, such that it always increases along the

same lines as our source code branching. [Roy Fielding]

*) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94

Changes with Apache 1.2.1

*) SECURITY: Don't serve file system objects unless they are plain files,

symlinks, or directories. This prevents local users from using pipes

or named sockets to invoke programs for an extremely crude form of

CGI. [Dean Gaudet]

*) SECURITY: HeaderName and ReadmeName were settable in .htaccess and

could contain "../" allowing a local user to "publish" any file on

the system. No slashes are allowed now. [Dean Gaudet]

*) SECURITY: It was possible to violate the symlink Options using mod_dir

(headers, readmes, titles), mod_negotiation (type maps), or

mod_cern_meta (meta files). [Dean Gaudet]

*) SECURITY: Apache will refuse to run as "User root" unless

BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]

*) CONFIG: If a symlink pointed to a directory then it would be disallowed

if it contained a .htaccess disallowing symlinks. This is contrary

to the rule that symlink permissions are tested with the symlink

options of the parent directory. [Dean Gaudet] PR#353

*) CONFIG: The LockFile directive can be used to place the serializing

lockfile in any location. It previously defaulted to /usr/tmp/htlock.

[Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,

Marc Slemko]

*) Request processing now retains state of whether or not the request

body has been read, so that internal redirects and subrequests will

not try to read it twice (and block). [Roy Fielding]

*) Add a placeholder in modules/Makefile to avoid errors with certain

makes. [Marc Slemko]

*) QUERY_STRING was unescaped in mod_include, it shouldn't be.

[Dean Gaudet] PR#644

*) mod_include was not properly changing the current directory.

*) Attempt to work around problems with third party libraries that do not

handle high numbered descriptors (examples include bind, and

solaris libc). On all systems apache attempts to keep all permanent

descriptors above 15 (called the low slack line). Solaris users

can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS

log files more feasible. If this causes trouble please report it,

you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
