590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater r->filename was tested by dir/file_walk, we need to 500 at the very

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the security and robustness of 2.0.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Status: still need to decide where this goes, OtherBill comments...

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater we need to look at halting this in the 'default handler' case,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater and that implies pushing the 'handler election' into the request

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater internal processing phase from the run request phase.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * There is a bug in how we sort some hooks, at least the pre-config

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater hook. The first time we call the hooks, they are in the correct

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater order, but the second time, we don't sort them correctly. Currently,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the modules/http/config.m4 file has been renamed to

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater modules/http/config2.m4 to work around this problem, it should moved

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater back when this is fixed. rbb

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * The Add...Filter and Set...Filter directives do not allow the

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater administrator to order filters, beyond the order of filename (mime)

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater extensions. It isn't clear if Set...Filter(s) should be inserted

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater before or after the Add...Filter(s) which are ordered by sequence of

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater filename extensions. At minimum, some sort of +-[0-10] syntax seems

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater like the quickest fix for a 2.0 gold release.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * mod_negotiation needs a new option or directive, something like

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater ForceLanguagePriority, to fall back to the LanguagePriority

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater directive instead of returning a "no acceptable variant" error.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Status: Bill has some code in his tree that accomplishes

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater this, and will commit it Friday after it's tested.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * Fold mod_auth_db features back into mod_auth_dbm, and depricate it.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater This can't wait until we have a 2.0-gold release, if folks need

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater to move over to auth_dbm, we can't do that to them after 2.0 gold.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Status: Ian says.. auth_dbm can now handle multiple DBM types,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater is this still an issue?

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Vote: Remove mod_auth_db

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Status: Aaron is working on converting INTRAPROCESS

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater to apr_thread_mutex_t types. Full replacements for

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater LOCKALL and CROSS_PROCESS are not yet complete on all

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater platforms, and should only be used in MPMs like worker

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater with limited OS exposure.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * ap_create_scoreboard() can exit the process, leaving stuff like

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater mod_cgid's daemon process stranded. Either ap_create_scoreboard()

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater needs to be called at a different time or the pre-mpm hook needs

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater to be able to return an error code.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic UpdaterRELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * Add a Logging Directive to exclude logging based on mime type.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Lars Says:

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater But is matching on mime-types really a required feature?

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater IMHO most people are happy with the current conditional logging

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater feature, e.g., matching on REQUEST_URI.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater I tend to be -1 on your patch Ian, because the directive is too

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater specific. We either need a more generic one or just stick with

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the current (or an enhanced) conditional logging functionality.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Large Sites/Sites with other heavy CPU loads need a 'cheap'

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater way to exclude 90% of all log lines (eg images)

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Regex Matching takes ~5-10 times longer than a simple hash get.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Justin says: If we get it working on AIX, we can enable this

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater on all platforms and clean up our build system

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater somewhat.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * Handling of %2f in URIs. Currently both 1.3 and 2.0

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater completely disallow %2f in the request URI path (see

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater ap_unescape_url() in util.c). It's permitted and passed

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater through in the query string, however. Roy says the

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater original reason for disallowing it, from five years ago,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater was to protect CGI scripts that applied PATH_INFO to

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater a filesystem location and which might be tricked by

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater ..%2f..%2f(...). We *should* allow path-info of the

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater form 'http://foo.com/index.cgi/path/to/path%2finfo'.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Since we've revamped a lot of our processing of path

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater segments, it would be nice to allow this, or at least

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater allow it conditionally with a directive.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater * FreeBSD, threads, and worker MPM. All seems to work fine

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater if you only have one worker process with many threads. Add

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater a second worker process and the accept lock seems to be

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater lost. This might be an APR issue with how it deals with

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the child_init hook (i.e. the fcntl lock needs to be resynced).

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater More examination and analysis is required.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Justin says: So, FreeBSD-CURRENT and Cywin have the same

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater problem. Yum. If another platform has this

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater with worker, this becomes a showstopper.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Aaron says: I spent some time disecting this and have come to

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the conclusion that it is not a problem in the worker MPM

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater (or at least, it is not isolated to a problem in worker).

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater I'll list some of the problems I'm seeing in case someone

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater else wants to pick up where I've left off:

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater - Delivery of just about any signal to one of the child

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater processes will send it into an infinite loop as well.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater - Even though the parent is spinning out of control,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater at first the child or children will appear to work

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater properly. At times it is possible to get it into a state,

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater however, where a request will hang until another concurrent

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater request "kicks" the first, at which point the second will

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater hang. My theory is that this has to do with the

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater pthread_cond_*() implementation in FreeBSD, but it's still

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater possible that it is in APR.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater Justin adds: Oh, FreeBSD threads are implemented entirely with

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater select()/poll()/longjmp(). Welcome to the nightmare.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater So, that means a ktrace output also has the thread

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater scheduling internals in it (since it is all the same to

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater the kernel). Which makes it hard to distinguish between

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater our select() calls and their select() calls.

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater *bangs head on wall repeatedly* But, some of the libc_r

590c12cfe3b9a179ab2faa1be791a069c81882e0Automatic Updater 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, and

mod_proxy are switched to the new logic.

However, ap_getline() still needs to be refactored out. But,

there's a problem there: ap_getline() peeks ahead for MIME

continuation (first character on line is space or \t) and

stores unused data in core_request_config which violates the

abstraction. That's cheating. So, we may not be able to

implement this without setting some data aside (yuck!).

I believe this is OtherBill's main complaint with the current

filtering.

AIUI (correct me if I'm wrong!), OtherBill believes we

should have a pushback option so that we can return unread

data - this would solve this case. However, my question to

him is how do we handle stuff like mod_ssl - we can't "unread"

data. So, do we have two brigades for each filter? An in

brigade and a returned brigade? That seems messy. To

everyone else, can we refactor ap_getline() without pushback

and how?

* 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?

* 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: Get the SINGLE_LISTEN_UNSERIALIZED_ACCEPT

optimization working in worker. prefork's new design for how

to notice data on the pod should be sufficient.

* 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.

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

* 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.

* 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.

Status: Mladen Turk has posted several patches and ideas.

Key question, part of htpasswd, or a seperate utility?

prefer htpasswd:

prefer seperate: OtherBill

* 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)

-0: Cliff (I think the default config should be the safest possible)

* Fix the worker MPM to use POD to kill child processes instead

of ap_os_killpg, regardless of how they should die. (Ryan Bloom)

* orig_ct in the byterange/multipart handling may not be

needed. Apache 1.3 just never stashed "multipart" into

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.
