1N/APlease consult the following STATUS files for information
1N/ACURRENT RELEASE NOTES:
1N/A * 34 status: Let's get all API changes and showstoppers in this one.
1N/AFINAL RELEASE SHOWSTOPPERS:
1N/A * If any request gets to the core handler, without a flag that this
1N/A end of the ap_process_request_internal() processing. This provides
1N/A authors of older modules better compatibility, while still improving
1N/A the security and robustness of 2.0.
1N/A Status: still need to decide where this goes, OtherBill comments...
1N/A Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
1N/A we need to look at halting this in the 'default handler' case,
1N/A and that implies pushing the 'handler election' into the request
1N/A internal processing phase from the run request phase.
1N/A Jim asks: would a stopgap be something bogus like adding another
1N/A flag to request_rec ala eos_sent and before we OK, if not set
1N/A Jeff says: reviewing the original message and the one
1N/A follow-up (also from OtherBill) it looks like OtherBill had a
1N/A good handle on the problem, though I wonder why not just put a
1N/A be in request_rec; a better place is core_request_config)
1N/A * We need to find out the right place to add the AddOutputFilterByType
1N/A directive. mod_mime? No. core with fixups? That's what it is now.
1N/A ap_pass_brigade() hook? As a filter that runs at HTTP_HEADER stage?
1N/A This needs to be resolved before the next public release.

1N/A BillS is working on this...
1N/A * API changes planned for 2.0 that should happen before the
1N/A * Free lists for bucket allocation
1N/A * We do not properly substitute the prefix-variables in the configuration
1N/A scripts or generated-configs. (
i.e. if sysconfdir is etc,
1N/A Aaron says: This is not a showstopper, these problems have existed
1N/A for as long as I can remember. It would be nice to fix
1N/A them but they are not new.
1N/A * Address popular PRs
1N/A * Win32 doesn't install as service correctly [9863, 9914, 9961]
1N/A * Don't forget to reversion mod_ssl, which is currently listed
1N/A * Should we always build binaries statically unless otherwise

1N/A "gracefully" self-terminate. Or maybe we should make it a runtime
1N/A option, or have a concept of 2 parent processes (one being a

1N/A Make it runtime configurable: Aaron, Jim, Justin

1N/A * Make the worker MPM the default MPM for threaded Unix boxes.
1N/A +1: Justin, Ian, Cliff
1N/A -0: Aaron (premature decision, needs more discussion), Lars
1N/ARELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
1N/A * Convert all instances of the old apr_lock_t type to the new
1N/A Status: Aaron has converted all but the perchild MPM to
1N/A use the new lock API. Since perchild has been put
1N/A on the back burner, this is no longer a showstopper.
1N/A Aaron will patch perchild as soon as it becomes
1N/A * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
1N/A how the Perchild MPM should be re-written. It hasn't worked
1N/A correctly since filters were added because it wasn't possible to
1N/A get the content that had already been written and the socket at
1N/A the same time. This mode lets us do that, so the MPM can be
1N/A * htpasswd blindly processes the file you give it, and does no
1N/A sanity checking before totally corrupting whatever file it was
1N/A you thought you had. It should check the input file and bail
1N/A if it finds non-comment lines that do not contain exactly 1
1N/A Message-ID: <20020217150457.A31632@clove.org>
1N/A * Can a static httpd be built reliably?
1N/A Message-ID: <20020207142751.T31582@clove.org>
1N/A * [Ken] Test suite failures:
1N/A o worker is also failing some of the 'cgi' subtests
1N/A Justin says: "Worker should be fine and passes httpd-test here.
1N/A If you can provide evidence that it can be reproduced
1N/A outside of httpd-test, then it's a showstopper. I
1N/A think it's a perl or a httpd-test problem."
1N/A Not a showstopper: Justin
1N/A * Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
1N/A removed if possible.
1N/A Message-ID: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>
1N/A * There is a bug in how we sort some hooks, at least the pre-config
1N/A hook. The first time we call the hooks, they are in the correct
1N/A order, but the second time, we don't sort them correctly. Currently,
1N/A back when this is fixed. rbb
1N/A Justin says: "Is this really a showstopper? This has been here
1N/A forever. What's wrong? Does this have to do with
1N/A Not a showstopper: Justin, BrianP, trawick, gregames
1N/A administrator to order filters, beyond the order of filename (mime)
1N/A filename extensions. At minimum, some sort of +-[0-10] syntax seems
1N/A like the quickest fix for a 2.0 gold release.
1N/A Justin says: "Could we delay this for a point release or 2.1?"
1N/A Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
1N/A * Get perchild to work on platforms other than Linux. This
1N/A descriptors between vhost child groups. An API was proposed
1N/A Message-ID: <20020111115006.K1529@clove.org>
1N/A * CGI single-byte reads
1N/A BrianP suggests that this is caused by the ap_scan_script_header_err()
1N/A routine, which will do single-byte reads until it finds the end
1N/A of the header, at which point it constructs a pipe-bucket (buffered)
1N/A Proposed solution in:
1N/A Message-ID: <3C36ADAF.60601@cnet.com>
1N/A * Try to get libtool inter-library dependency code working on AIX.
1N/A Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
1N/A Justin says: If we get it working on AIX, we can enable this
1N/A on all platforms and clean up our build system
1N/A Jeff says: I thought I tested a patch for you sometime in
1N/A January that you were going to commit within a few
1N/A * Handling of %2f in URIs. Currently both 1.3 and 2.0
1N/A completely disallow %2f in the request URI path (see
1N/A ap_unescape_url() in
util.c). It's permitted and passed
1N/A through in the query string, however. Roy says the
1N/A original reason for disallowing it, from five years ago,
1N/A was to protect CGI scripts that applied PATH_INFO to
1N/A a filesystem location and which might be tricked by
1N/A ..%2f..%2f(...). We *should* allow path-info of the
1N/A Since we've revamped a lot of our processing of path
1N/A segments, it would be nice to allow this, or at least
1N/A allow it conditionally with a directive.
1N/A * FreeBSD, threads, and worker MPM. All seems to work fine
1N/A if you only have one worker process with many threads. Add
1N/A a second worker process and the accept lock seems to be
1N/A lost. This might be an APR issue with how it deals with
1N/A the child_init hook (
i.e. the fcntl lock needs to be resynced).
1N/A More examination and analysis is required.
1N/A Status: This has also been reported on Cygwin.
1N/A Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
1N/A Justin says: So, FreeBSD-CURRENT and Cywin have the same
1N/A problem. Yum. If another platform has this
1N/A with worker, this becomes a showstopper.
1N/A Aaron says: I spent some time disecting this and have come to
1N/A the conclusion that it is not a problem in the worker MPM
1N/A (or at least, it is not isolated to a problem in worker).
1N/A I'll list some of the problems I'm seeing in case someone
1N/A else wants to pick up where I've left off:
1N/A - Delivery of just about any signal to one of the child
1N/A processes will send it into an infinite loop as well.
1N/A - Even though the parent is spinning out of control,
1N/A at first the child or children will appear to work
1N/A properly. At times it is possible to get it into a state,
1N/A however, where a request will hang until another concurrent
1N/A request "kicks" the first, at which point the second will
1N/A hang. My theory is that this has to do with the
1N/A pthread_cond_*() implementation in FreeBSD, but it's still
1N/A possible that it is in APR.
1N/A Justin adds: Oh, FreeBSD threads are implemented entirely with
1N/A select()/poll()/longjmp(). Welcome to the nightmare.
1N/A So, that means a ktrace output also has the thread
1N/A scheduling internals in it (since it is all the same to
1N/A the kernel). Which makes it hard to distinguish between
1N/A our select() calls and their select() calls.
1N/A *bangs head on wall repeatedly* But, some of the libc_r
1N/A files have a DBG_MSG #define. This is moderately helpful
1N/A when used with -DNO_DETACH. The kernel scheduler isn't
1N/A waking up the threads on a select(). Yum. And, I bet
1N/A those decrementing select calls have to do with the
1N/A scheduler. Time to brush up on our OS fundamentals.
1N/A * There is increasing demand from module writers for an API
1N/A that will allow them to control the server � la apachectl.
1N/A Reasons include sole-function servers that need to die if
1N/A an external dependency (
e.g., a database) fails, et cetera.
1N/A Perhaps something in the (ever more abused) scoreboard?
1N/A rbb: I don't believe the scoreboard is the correct mechanism
1N/A for this. We already have a pipe that goes between parent
1N/A and child for graceful shutdown events, along with an API that
1N/A can be used to send a message down that pipe. In threaded MPMs,
1N/A it is easy enough to make that one pipe be used for graceful
1N/A and graceless events, and it is also easy to open that pipe
1N/A to both parent and child for writing. Then we just need to
1N/A figure out how to do graceless on non-threaded MPMs.
1N/A * Allow the DocumentRoot directive within <Location > scopes? This
1N/A and in-your-face.) DocumentRoot unset would be accepted [and would
1N/A not permit content to be served, only virtual resources such as
1N/A server-info or server-status.
1N/A This proposed change would _not_ depricate Alias.
1N/A * Win32: Rotatelogs sometimes is not terminated when Apache
1N/A goes down hard. FirstBill was looking at possibly tracking the
1N/A child's-child processes in the parent process.
1N/A OtherBill asks, wasn't this fixed?
1N/A stoddard: Not fixed. Shared scoreboard might offer a good
1N/A way for the parent to keep track of 'other child' processes
1N/A and whack them if the child goes down.
1N/A * Win32: Add a simple hold console open patch (wait for close or
1N/A the ESC key, with a nice message) if the server died a bad
1N/A death (non-zero exit code) in console mode.
1N/A Resolution: bring forward same ugly hacks from 1.3.13-.20
1N/A * Port of mod_ssl to Apache 2.0:
1N/A remaining work includes:
1N/A (2) Enabling SSL extentions
1N/A (3) Trying to seperate the https filter logic from mod_ssl -
1N/A This is to facilitate other modules that wish to use the https
1N/A filter or the mod_ssl logic or both as required.
1N/A * Performance & Debug: Eliminate most (and perhaps all) of the
1N/A light weight memory management functions that allow freeing
1N/A memory (putting it back into a memory pool) when it is no
1N/A longer needed. Enabling simple debugging features like guard
1N/A bands, double free detection, etc. would be cool but certainly
1N/A not a hard requirement.
1N/A Status: Cliff started to implement this using SMS as has
1N/A been discussed at length for months, but since
1N/A SMS is not being used anywhere else in the server,
1N/A several people expressed the opinion that we should
1N/A get rid of it entirely, meaning that the buckets
1N/A need their own memory management (free list) functions.
1N/A Cliff will implement that this weekend so we at least
1N/A * Eliminate unnecessary creation of pipes in mod_cgid
1N/A * Document mod_file_cache.
1N/A * Platforms that do not support fork (primarily Win32 and AS/400)
1N/A Architect start-up code that avoids initializing all the modules
1N/A in the parent process on platforms that do not support fork.
1N/A would eliminate some code in the Win32 branch that essentially
1N/A duplicates what is in APR.
1N/A * There are still a number of places in the code where we are
1N/A losing error status (
i.e. throwing away the error returned by a
1N/A system call and replacing it with a generic error code)
1N/A * Mass vhosting version of suEXEC.
1N/A the dbmmanage employs the first-matched dbm format. This is not
1N/A necessarily the library that Apache was built with. Aught to
1N/A rewrite dbmmanage upon installation to bin/ with the proper library
1N/A for predictable mod_auth_dbm administration.
1N/A Questions; htdbm exists, time to kill dbmmanage, or does it remain
1N/A useful as a perl dbm management example? If we keep it,
1N/A do we address the issue above?
1N/A * Integrate mod_dav.
1N/A Some additional items remaining:
1N/A - case_preserved_filename stuff
1N/A (use the new canonical name stuff?)
1N/A - find a new home for ap_text(_header)
1N/A - is it possible to remove the DAV: namespace stuff from util_xml?
1N/A * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
1N/A are a bit wonky. The function should probably be exposed as a utility
1N/A function (such as ap_translate_url2fs() or ap_validate_fs_url() or
1N/A something). Another approach would be a new hook phase after
1N/A "translate" which would allow the module to munge what the
1N/A translation has decided to do.
1N/A Status: Greg +1 (volunteers), Ryan +1
1N/A calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
1N/A ap_sort_hooks() [to reduce the logic in main()]
1N/A * read the config tree just once, and process N times (as necessary)
1N/A * (possibly) use UUIDs in mod_unique_id
and/or mod_usertrack
1N/A * (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
1N/A into a VirtualHost container) to 2.0.
1N/A * callers of ap_run_create_request() should check the return value
1N/A for failure (Doug volunteers)
1N/A * Win32: Get Apache working on Windows 95/98. The following work
1N/A (at least) needs to be done:
1N/A - Document warning that OSR2 is required (for Crypt functions, in
1N/A rand.c, at least.) This could be resolved with an SSL library, or
1N/A randomization in APR itself.
1N/A actually works) and add in a splash of Win9x service code.
1N/A * In order to use a DSO version of mod_ssl we have to link with
1N/A -lssl and -lcrypto. A workaround is in place right now where the
1N/A entire EXTRA_LIBS macro is being appended to the objects list, but
1N/A this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT
1N/A autoconf function or come up with some other autoconf checks to
1N/A search for libssl and libcrypto and properly add them to mod_ssl's
1N/A * Fix the worker MPM to use POD to kill child processes instead
1N/A of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
1N/A * mod_cache: handle cache_control: no_cache "field_name" to enable
1N/A cacheing the response w/o header "field_name"
1N/A See RFC2616 section 14.9.1
1N/A * Scoreboard structures could be changed in the future such that
1N/A proper alignment is not maintained, leading to segfaults on
1N/A some systems. Cliff posted a patch to deal with this issue but
1N/A later recanted. See this message to dev@apr.apache.org:

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.
