a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsync The binbuild issue isn't AIX. It is

34370838dcf25e846b2a3b0032ce1eb47a1eb351vboxsync Handle this by patching binbuild.sh for a

a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsync beta roll or putting a patch in the README for

end of the ap_process_request_internal() processing. This provides

authors of older modules better compatibility, while still improving

the security and robustness of 2.0.

Status: still need to decide where this goes, OtherBill comments...

Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>

we need to look at halting this in the 'default handler' case,

and that implies pushing the 'handler election' into the request

internal processing phase from the run request phase.

* Convert all instances of the old apr_lock_t type to the new

types (once they are fully supported in APR).

Status: Aaron is working on converting INTRAPROCESS

to apr_thread_mutex_t types. Full replacements for

LOCKALL and CROSS_PROCESS are not yet complete on all

platforms, and should only be used in MPMs like worker

with limited OS exposure.

BrianP asks: "Is this really a showstopper?"

IanH says: "If we don't do it before we go live we will have 2

different API's to support in APR"

* A binbuild installation picks up the right libraries when

running apachectl because we set the appropriate environment

variable, but ab, htpasswd, etc. don't know how to pick up apr,

apr-util, etc.

Message-ID: <20020116000226.GA15991@ebuilt.com>

Justin says: "You could always build all of the binaries

statically if you don't want to let libtool

handle it. At most, I don't consider this a

a release showstopper as it is a packaging issue."

Ken sez: "Showstopper because, until it's the default, it

violates the P of LA. Binaries will give strange

errors and not run if moved."

Status: Aaron volunteers: I'll commit a patch to allow all

the support binaries to be built statically against

libapr/libaprutil/etc and then enable it in binbuild.

gregames says: what about httpd? yeah, it works at the moment

if you use apachectl. But I've already heard

complaints about not being able to execute

httpd directly.

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

* Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be

removed if possible.

Message-ID: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>

* 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

Justin says: "Is this really a showstopper? This has been here

forever. What's wrong? Does this have to do with

autoconf or m4?"

Not a showstopper: Justin, BrianP, trawick, gregames

* The Add...Filter and Set...Filter directives do not allow the

administrator to order filters, beyond the order of filename (mime)

extensions. It isn't clear if Set...Filter(s) should be inserted

before or after the Add...Filter(s) which are ordered by sequence of

filename extensions. At minimum, some sort of +-[0-10] syntax seems

like the quickest fix for a 2.0 gold release.

Justin says: "Could we delay this for a point release or 2.1?"

Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,

gregames

* Get perchild to work on platforms other than Linux. This

descriptors between vhost child groups. An API was proposed

* Recent changes to ap_rgetline may have broken EBCDIC boxes.

Message-ID: <20020122072605.GF28051@ebuilt.com>

Justin says: "I don't have an EBCDIC box to test on. A potential

solution is to split out ap_rgetline into two

functions as described in this message."

gregames says: I see the breakage now, and volunteer to fix it

when things calm down a little. It looks OK when

there are complete lines and no mime continuations.

* Modify the worker MPM so that it doesn't need to create and

destroy a pool for each request--possibly by adopting a

leader/follower model in which each worker owns a persistent

ptrans pool (like the prefork MPM) and the workers take

turns acting as listeners...this approach might also help

reduce context-switching

* CGI single-byte reads

BrianP suggests that this is caused by the ap_scan_script_header_err()

routine, which will do single-byte reads until it finds the end

of the header, at which point it constructs a pipe-bucket (buffered)

to read from.

Proposed solution in:

Message-ID: <3C36ADAF.60601@cnet.com>

* Try to get libtool inter-library dependency code working on AIX.

Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>

Justin says: If we get it working on AIX, we can enable this

on all platforms and clean up our build system

somewhat.

Jeff says: I thought I tested a patch for you sometime in

January that you were going to commit within a few

days.

* Handling of %2f in URIs. Currently both 1.3 and 2.0

completely disallow %2f in the request URI path (see

ap_unescape_url() in util.c). It's permitted and passed

through in the query string, however. Roy says the

original reason for disallowing it, from five years ago,

was to protect CGI scripts that applied PATH_INFO to

a filesystem location and which might be tricked by

..%2f..%2f(...). We *should* allow path-info of the

form 'http://foo.com/index.cgi/path/to/path%2finfo'.

Since we've revamped a lot of our processing of path

segments, it would be nice to allow this, or at least

allow it conditionally with a directive.

* FreeBSD, threads, and worker MPM. All seems to work fine

if you only have one worker process with many threads. Add

a second worker process and the accept lock seems to be

lost. This might be an APR issue with how it deals with

the child_init hook (i.e. the fcntl lock needs to be resynced).

More examination and analysis is required.

Status: This has also been reported on Cygwin.

Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)

Justin says: So, FreeBSD-CURRENT and Cywin have the same

problem. Yum. If another platform has this

with worker, this becomes a showstopper.

Aaron says: I spent some time disecting this and have come to

the conclusion that it is not a problem in the worker MPM

(or at least, it is not isolated to a problem in worker).

I'll list some of the problems I'm seeing in case someone

else wants to pick up where I've left off:

- Delivery of just about any signal to one of the child

processes will send it into an infinite loop as well.

- Even though the parent is spinning out of control,

at first the child or children will appear to work

properly. At times it is possible to get it into a state,

however, where a request will hang until another concurrent

request "kicks" the first, at which point the second will

hang. My theory is that this has to do with the

pthread_cond_*() implementation in FreeBSD, but it's still

possible that it is in APR.

Justin adds: Oh, FreeBSD threads are implemented entirely with

select()/poll()/longjmp(). Welcome to the nightmare.

So, that means a ktrace output also has the thread

scheduling internals in it (since it is all the same to

the kernel). Which makes it hard to distinguish between

our select() calls and their select() calls.

*bangs head on wall repeatedly* But, some of the libc_r

files have a DBG_MSG #define. This is moderately helpful

when used with -DNO_DETACH. The kernel scheduler isn't

waking up the threads on a select(). Yum. And, I bet

those decrementing select calls have to do with the

scheduler. Time to brush up on our OS fundamentals.

* There is increasing demand from module writers for an API

that will allow them to control the server � la apachectl.

Reasons include sole-function servers that need to die if

an external dependency (e.g., a database) fails, et cetera.

Perhaps something in the (ever more abused) scoreboard?

rbb: I don't believe the scoreboard is the correct mechanism

for this. We already have a pipe that goes between parent

and child for graceful shutdown events, along with an API that

can be used to send a message down that pipe. In threaded MPMs,

it is easy enough to make that one pipe be used for graceful

and graceless events, and it is also easy to open that pipe

to both parent and child for writing. Then we just need to figure

out how to do graceless on non-threaded MPMs.

* revamp the input filter behavior, per discussions since

February (and especially at the hackathon last

April). Specifically, ap_get_brigade will return a brigade with

*up to* a specific number of bytes, or a "line" of data. The

read may be blocking or nonblocking. ap_getline() will be

refactored into apr_brigade_getline(), and then DECHUNK can use

f->next (ap_getline will always read "top of input stack"). Also

fix the bug where request body content will end up closing the

connection (buggering up persistent conns).

Status: Justin is working on this as fast as he can.

The core input filters, HTTP-related filters, mod_ssl,

mod_proxy, and ap_[r]getline are switched to the new logic.

- socket bucket and core input filter changes. see end of

message ID (Feb 27): <20010227075326.S2297@lyra.org>

* Allow the DocumentRoot directive within <Location > scopes? This

allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed

by a <Directory /somepath/foo> to become simply

<Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible

and in-your-face.) DocumentRoot unset would be accepted [and would

not permit content to be served, only virtual resources such as

server-info or server-status.

This proposed change would _not_ depricate Alias.

* Win32: Rotatelogs sometimes is not terminated when Apache

goes down hard. FirstBill was looking at possibly tracking the

child's-child processes in the parent process.

OtherBill asks, wasn't this fixed?

stoddard: Not fixed. Shared scoreboard might offer a good

way for the parent to keep track of 'other child' processes

and whack them if the child goes down.

* 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.

Resolution: bring forward same ugly hacks from 1.3.13-.20

* Port of mod_ssl to Apache 2.0:

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

remaining work includes:

(1) stablizing/optimizing the SSL filter logic

(2) Enabling the various SSL caching mechanisms (shmcb, shmht)

(3) Enabling SSL extentions

(4) Trying to seperate the https filter logic from mod_ssl -

This is to facilitate other modules that wish to use the https

filter or the mod_ssl logic or both as required.

Justin: mod_ssl filter logic is redone, so that should be fine.

Madhu has submitted a patch for SSL caching - however, I

am -0 on that patch as I *think* we could implement the

shared memory another way that is much cleaner (i.e.

treat shmem directly as a dbm via APR routines). Justin

also thinks that the https filter logic may be sufficiently

decoupled now, but isn't really sure.

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

malloc/free calls 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.

Status: Cliff started to implement this using SMS as has

been discussed at length for months, but since

SMS is not being used anywhere else in the server,

several people expressed the opinion that we should

get rid of it entirely, meaning that the buckets

need their own memory management (free list) functions.

Cliff will implement that this weekend so we at least

have something to look at/compare with.

* 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.

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

Common logging API.

* Document mod_file_cache.

* 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_dbm administration.

Questions; htdbm exists, time to kill dbmmanage, or does it remain

useful as a perl dbm management example? If we keep it,

do we address the issue above?

* use apu_dbm in mod_auth_dbm

Status: Greg +1 (low-priority volunteer)

Justin says: "Seems like this is already there, so should we just

remove the other DBM code in that file? If you want

to use gdbm, or dbm, etc, you should tell apr-util."

Will says: "bs - I may choose the fastest - most efficient native

dbm implementation, for shared proc caches, ssl session

caching, etc, but that has nothing to do with maintaining

a userlist via dbm, which has to remain readable between

builds/machines, etc. The use-multiple database schema

for apr-util would let us do this with just apr, though."

Ian says: "multi-dbm is in, but it still has ndbm support hardcoded

is this still required? isn't ndbm supported via gdbm?"

* 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

* callers of ap_run_create_request() should check the return value

for failure (Doug volunteers)

* 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.) This could be resolved with an SSL library, or

randomization in APR itself.

- Bring the Win9xConHook.dll from 1.3 into 2.0 (no sense till it

actually works) and add in a splash of Win9x service code.

* In order to use a DSO version of mod_ssl we have to link with

-lssl and -lcrypto. A workaround is in place right now where the

entire EXTRA_LIBS macro is being appended to the objects list, but

this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT

autoconf function or come up with some other autoconf checks to

search for libssl and libcrypto and properly add them to mod_ssl's

link flags.

* Make the worker MPM the default MPM for threaded Unix boxes.

+1: Justin, Jeff, Ian

-0: Aaron (premature decision, needs more discussion), Lars

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