ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder * File handle caching in mod_file_cache is broken in the multi

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder threaded MPMs. The original intent of caching file handles

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder was that these handles would ONLY be used in an apr_sendfile()

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder call. With recent optimizations added to core_output_filter

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder to pipeline output byte streams, we actually read bytes from

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder these cached file handles into buffers. The problem is that

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder while it is okay for multiple threads to share a file handle

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder for use on a sendfile call (because the filepointer is not used,

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder in sendfile) it is NOT okay for threads to share a file handle

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder for reads or writes (because the filepointer is used in reads

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder and writes). This may also be broken on a few quirky platforms

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder whose sendfile() actually uses the file pointer. Jeff was looking

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder into that.

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder Potential Solutions:

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder 1. We either need to ensure that a cached file handle is only

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder used on a sendfile call (Bill prefers this solution. I think.).

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder 2. Cliff Woolley has some ideas about a custom bucket type

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder that would recognise when an apr_file_t is cached (thus shared

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder across threads) and do the right thing to ensure that the

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder filepointer does not get trashed. The idea here is that the

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder "cacheable" file bucket would never allow its file handle to be

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder read by any method OTHER than sendfile. Attempts to do otherwise

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder would result in the file being re-opened for sync io into the

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder request pool, and the new file handle would get put into a regular

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder file bucket which would then be read. This method thus incorporates

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder the spirit of solution #1 while having a fall-back protection

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder scheme. Note that mod_file_cache can still attempt to

79bf62fdeb8f4775386201433fe2818358fc1a51Till Mossakowski be discriminatory and DECLINE requests that it believes will

ebd2b49c422ae4a74eb9df9740d86bdbecd2a82cLutz Schröder result in an apr_bucket_read() call; this solution just allows

it to not worry TOO much about missing some cases. Note that

no locking is involved, and in the worst case (ie, when the cached

file bucket is read) we are no worse off performance-wise than

if we'd just DECLINED in the first place. Patch forthcoming.

3. You can share a file handle across threads in Windows if you

open the file for OVERLAPPED io. A file opened for overlapped

io does not have a file pointer; each thread must manage

tracking its location in the file explicity. This is a cool

feature IMHO. APR would need to be expanded to handle

reading and writing to files opened for overlapped io

(specifically to manage a per-thread file pointer and handle

async io events internal to APR). This doesn't fix the problem

under *ix though.

* There is a bug in how we sort some hooks, at least the pre-config

hook. The first time we call the hooks, they are in the correct

order, but the second time, we don't sort them correctly. Currently,

the modules/http/config.m4 file has been renamed to

modules/http/config2.m4 to work around this problem, it should moved

back when this is fixed. rbb

* Root all file systems with <Directory /> for WIN32/OS2/NW permissions

Status: patch brought forward from 1.3.14

WIN32 and OS2 need review [William Rowe, Brian Harvard]

* Win32: Get Apache working on Windows 95/98. The following work

(at least) needs to be done:

- winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT

specific code that is still not in NT only code paths

- IOL binds to APR sendfile, implemented with TransmitFile, which

is not available on 95/98.

- Document warning that OSR2 is required (for Crypt functions, in

rand.c, at least.)

* Win32: Test access logging with multiple threads. Will the

native file I/O calls serialize automagically like the

CRT calls or do we need to add region locking each time

we access the logs?

Status:

* Win32: Complete the revamp the service environment and relocation

into the WinNT MPM. Changes ServerRoot service registry

parameter into ConfigArgs for multiple service startup parameters.

Problems to fix in the revamp: -k shutdown/restart are broken,

signals are not being acknowledged. Close window and shutdown

also seem out of sorts.

OtherBill is working on this and will finish over the weekend.

* We need a thread-safe resolver, at least on Unix.

Status: The best known candidate would be something from

BIND v9.

Status: Greg asks, "why? doesn't gethostbyname_r() handle this?"

* The AddInputFilter and AddOutputFilter directives do not allow the

administrator to remove or reorder filters. Once a filter is added

in a container, it is present in any subcontainers. It can only be

added to the filter chain after any filters specified in enclosing

containers.

* remove the --disable-shared from the subdir config of APR(UTIL)

before the final release. (in fact, it might even be nice to

allow for Apache config/build against an already-installed

APR(UTIL))

Note: we need to do a "make install" for APR(UTIL) so the shared

libraries can be installed properly. We could also use that

point to install include files (rather than have Apache

know everything that needs to be installed from the

sub-packages). The original impetus for doing the

disable-shared was because the shared lib wasn't getting

installed and a "make clean" in aprutil would make Apache

fail to load.

* users who want to install third-party modules into the Apache

source tree (for static linking) need to have autoconf and

libtool installed. This is because the module needs to have its

config.m4 incorporated into ./configure, which means "buildconf"

must be run.

Note: This is in part because we have removed the "extra" directory.

In the Apache-2.0 repository, this directory had a config.m4

file that allowed people to add external modules by

specifying --with-module on the configure line.

* ap_vrprintf() needs to handle more than 4K

Status: Greg volunteers

* mod_dir should normally redirect ALL directory requests which do

not include a trailing slash on the URI. However, if a "notes"

flag is set (say, via BrowserMatch), this behavior will be

disabled for non-GET requests.

* Usability: Sanitize the MPM config directives. MaxClients in

the threaded MPM is totally misleading now as it has little to

do with limiting the number of clients (it limits the number

of child processes). Bill proposed nomenclature change to

something like "StartWorkers, MaxWorkers, etc." that could

apply to most all the MPMs (with some notable exceptions).

Bill would be happy with changing MaxClients to MaxServers

to make it agree with the operation of the StartServers

directive.

* A design problem with the scoreboard can cause the threaded

MPM to get in a state where it will no longer serve requests.

When MaxRequestsPerChild is hit, a threaded process will begin

allowing it's idle worker threads to exit. The child process

may have one (or a few) threads serving really long responses

over slow client connections, which will prevent the child

process from exiting. The problem is that the

perform_idle_server_maintenance code will NOT start a new

process to replace the dying child process until the dying child

has exited because the new child needs to use the old childs

space in the scoreboard. The scoreboard and

perform_idle_server_maintenance need to be redesigned.

Status: Several proposals discussed on new-httpd (April 16, 2001)

RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:

* Port of mod_ssl to Apache 2.0:

The current porting state is summarized in modules/ssl/README. The next

step is to figure out how the old three configuration contexts (global,

per-server, per-directory) can be ported to Apache 2.0 (especially the

global context which has to survive server restarts RSE still does not

know how to port). Then the remaining source files (which depend on the

configuration contexts) which are still tagged with "-" in

modules/ssl/README can be ported.

One more thing to figure out is how and when mod_ssl can provide the

interactive pass phrase dialog (in Apache 1.3 it used the first init

round [where tty was still not detached] and skipped the second init

round [where it was already detached]). Apache 2.0 requires (or already

has?) an official hook where such tty-dialogs can be performed.

RSE is on holiday until June 11th, 2001. After this he starts

working on mod_ssl again and tries to make mod_ssl running inside

Apache 2.0 by end of June. If anyone wants to help making mod_ssl

running in the meantime, feel free to make your hands dirty inside

modules/ssl/. Do whatever you think is appropriate to get it

running. I've no objections of any kind, except: just do not

remove any old functionality. Keep everything, even if it needs

#if 0...endif wrapped to not make trouble for you.

* Performance: Get SINGLE_LISTENER_UNSERIALIZED_ACCEPT

optimization working again. Bill would like to see this

working for the threaded MPM, then prefork.

* mod_tls is very specific to OpenSSL. Make the API calls

more generic to support other encryption libraries.

* Performance & Debug: Eliminate most (and perhaps all) of the

malloc/calloc/frees in the bucket brigade code. Need some

light weight memory management functions that allow freeing

memory (putting it back into a memory pool) when it is no

longer needed. Enabling simple debugging features like guard

bands, double free detection, etc. would be cool but certainly

not a hard requirement.

* Eliminate unnecessary creation of pipes in mod_cgid

* the autoconf setup should be fixed to default to using the

"Apache" layout from config.layout, and each variable settable

in a layout should be overridable on the command line. Plus,

what we do right now just doesn't seem to fully fit into how autoconf

works, eg. AC_PREFIX_DEFAULT issues.

Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>

* All of our MPMs should use APR for threads/processes. This

will allow us to error out if a threaded MPM is chosen on a

platform that doesn't support threads.

* Combine log_child and piped_log_spawn. Clean up http_log.c.

Common logging API.

* Document mod_file_cache.

* OS/2: Make mod_status work for spmt_os2 MPM.

* Win32: Win9x console window still won't play nice with the

close window, logoff and shutdown scenarios.

Status: OtherBill will move the patch forward from 1.3.15, once we

get our other Win9x issues solved.

* Win32: Add a simple hold console open patch (wait for close or

the ESC key, with a nice message) if the server died a bad

death (non-zero exit code) in console mode.

Status: OtherBill is bringing forward same ugly hack from 1.3.13

* Platforms that do not support fork (primarily Win32 and AS/400)

Architect start-up code that avoids initializing all the modules

in the parent process on platforms that do not support fork.

* Win32: Migrate the MPM over to use APR thread/process calls. This

would eliminate some code in the Win32 branch that essentially

duplicates what is in APR.

* There are still a number of places in the code where we are

losing error status (i.e. throwing away the error returned by a

system call and replacing it with a generic error code)

* Mass vhosting version of suEXEC.

* All DBMs suffer from confusion in support/dbmmanage (perl script) since

the dbmmanage employs the first-matched dbm format. This is not

necessarily the library that Apache was built with. Aught to

rewrite dbmmanage upon installation to bin/ with the proper library

for predictable mod_auth_db/dbm administration.

* use apu_dbm in mod_auth_dbm

Status: Greg +1 (low-priority volunteer)

* Integrate mod_dav.

Some additional items remaining:

- case_preserved_filename stuff

(use the new canonical name stuff?)

- find a new home for ap_text(_header)

- is it possible to remove the DAV: namespace stuff from util_xml?

* ap_core_translate() and its use by mod_mmap_static and mod_file_cache

are a bit wonky. The function should probably be exposed as a utility

function (such as ap_translate_url2fs() or ap_validate_fs_url() or

something). Another approach would be a new hook phase after

"translate" which would allow the module to munge what the

translation has decided to do.

Status: Greg +1 (volunteers), Ryan +1

* Explore use of a post-config hook for the code in http_main.c which

calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and

ap_sort_hooks() [to reduce the logic in main()]

* read the config tree just once, and process N times (as necessary)

* (possibly) use UUIDs in mod_unique_id and/or mod_usertrack

* (possibly) port the bug fix for PR 6942 (segv when LoadModule is put

into a VirtualHost container) to 2.0.

* shift stuff to mod_core.h

* APR-ize resolver stuff in mod_unique_id (Jeff volunteers)

* callers of ap_run_create_request() should check the return value

for failure (Doug volunteers)

MIME types for MNG and JNG files need adding to mime.types and

Other bugs that need fixing:

* MaxRequestsPerChild measures connections, not requests.

Until someone has a better way, we'll probably just rename it

"MaxConnectionsPerChild".

* Regex containers don't work in an intutive way

Status: No one has come up with an efficient way to fix this

behavior. Dean has suggested getting rid of regex containers

completely.

* SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a

sigwaiting thread. We need to work around this, perhaps unless

there is hope soon for a fixed glibc.

* orig_ct in the byterange/multipart handling may not be

needed. Apache 1.3 just never stashed "multipart" into

r->content_type. We should probably follow suit since the

byterange stuff doesn't want the rest of the code to see the

multipart content-type; the other code should still think it is

dealing with the <orig_ct> stuff.

Status: Greg volunteers to investigate (esp. since he was most

likely the one to break it :-)

Other features that need writing:

* Finish infrastructure in core for async MPMs

Status: post 2.0

* TODO in source -- just do an egrep on "TODO" and see what's there

Documentation that needs writing:

* Mod_status docs are needed.

* The concept of MPMs, especially if we ship more than one MPM for a

given platform

* New directives in the various MPMs and appropriate links from

obsolete directives in core.html to the MPM documentation.

* Revise manual/stopping.html and the last part of

manual/misc/perf-tuning.html to take account of the MPMs.

* API documentation

Status: Ben Laurie has written some hooks documentation

(apache-2.0/htdocs/hooks.html)

* Changes since 1.3.9 can be more easily seen in the commitlog file

dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0

which includes some of Roy's comments when the changes were

committed in rough change-sets by purpose. Note that the commitlog

does not show the contents of new files until later.
