4632N/APlease consult the following STATUS files for information
4632N/A * 34 status: Let's get all API changes and showstoppers in this one.
4632N/A * If any request gets to the core handler, without a flag that this
4632N/A end of the ap_process_request_internal() processing. This provides
4632N/A authors of older modules better compatibility, while still improving
4632N/A the security and robustness of 2.0.
4632N/A Status: still need to decide where this goes, OtherBill comments...
4632N/A Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
4632N/A we need to look at halting this in the 'default handler' case,
4632N/A and that implies pushing the 'handler election' into the request
4632N/A internal processing phase from the run request phase.
4632N/A Jim asks: would a stopgap be something bogus like adding another
4632N/A flag to request_rec ala eos_sent and before we OK, if not set
4632N/A * We need to find out the right place to add the AddOutputFilterByType
4632N/A directive. mod_mime? No. core with fixups? That's what it is now.
4632N/A ap_pass_brigade() hook? As a filter that runs at HTTP_HEADER stage?
4632N/A This needs to be resolved before the next public release.
4632N/A Message-ID: <018701c1b99c$f0f24310$0a01230a@KOJ>
4632N/A * API changes planned for 2.0 that should happen before the
4632N/A * Free lists for bucket allocation
4632N/A * We do not properly substitute the prefix-variables in the configuration
4632N/A scripts or generated-configs. (
i.e. if sysconfdir is etc,
4632N/A * Win32 doesn't install as service correctly [9863, 9914, 9961]
4632N/A * Don't be stupid and cd to a blank directory when doing installs
4632N/A * Should we always build binaries statically unless otherwise
4632N/A Message-ID: <20020129210006.B23512@Lithium.MeepZor.Com>
4632N/A * If the parent process dies, should the remaining child processes
4632N/A "gracefully" self-terminate. Or maybe we should make it a runtime
4632N/A option, or have a concept of 2 parent processes (one being a
4632N/A See: Message-ID: <3C58232C.FE91F19F@Golux.Com>
4632N/A Not self-destruct: BrianP, Ian, Cliff, BillS
4632N/A Make it runtime configurable: Aaron, Jim, Justin
4632N/A +0: Martin (while standing by, could it do
4632N/A * Make the worker MPM the default MPM for threaded Unix boxes.
4632N/A -0: Aaron (premature decision, needs more discussion), Lars
4632N/ARELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
4632N/A * Convert all instances of the old apr_lock_t type to the new
4632N/A Status: Aaron has converted all but the perchild MPM to
4632N/A use the new lock API. Since perchild has been put
4632N/A on the back burner, this is no longer a showstopper.
4632N/A Aaron will patch perchild as soon as it becomes
4632N/A * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
4632N/A how the Perchild MPM should be re-written. It hasn't worked
4632N/A correctly since filters were added because it wasn't possible to
4632N/A get the content that had already been written and the socket at
4632N/A the same time. This mode lets us do that, so the MPM can be
4632N/A * htpasswd blindly processes the file you give it, and does no
4632N/A sanity checking before totally corrupting whatever file it was
4632N/A you thought you had. It should check the input file and bail
4632N/A if it finds non-comment lines that do not contain exactly 1
4632N/A Message-ID: <20020217150457.A31632@clove.org>
4632N/A * Can a static httpd be built reliably?
4632N/A Message-ID: <20020207142751.T31582@clove.org>
4632N/A * [Ken] Test suite failures:
4632N/A o worker is also failing some of the 'cgi' subtests
4632N/A Justin says: "Worker should be fine and passes httpd-test here.
4632N/A If you can provide evidence that it can be reproduced
4632N/A outside of httpd-test, then it's a showstopper. I
4632N/A think it's a perl or a httpd-test problem."
4632N/A * Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be

4632N/A * There is a bug in how we sort some hooks, at least the pre-config
4632N/A hook. The first time we call the hooks, they are in the correct
4632N/A order, but the second time, we don't sort them correctly. Currently,
4632N/A back when this is fixed. rbb
4632N/A Justin says: "Is this really a showstopper? This has been here
4632N/A forever. What's wrong? Does this have to do with
4632N/A Not a showstopper: Justin, BrianP, trawick, gregames
4632N/A administrator to order filters, beyond the order of filename (mime)
4632N/A filename extensions. At minimum, some sort of +-[0-10] syntax seems
4632N/A like the quickest fix for a 2.0 gold release.
4632N/A Justin says: "Could we delay this for a point release or 2.1?"
4632N/A Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
4632N/A * Get perchild to work on platforms other than Linux. This
4632N/A descriptors between vhost child groups. An API was proposed
4632N/A Message-ID: <20020111115006.K1529@clove.org>
4632N/A BrianP suggests that this is caused by the ap_scan_script_header_err()
4632N/A routine, which will do single-byte reads until it finds the end
4632N/A of the header, at which point it constructs a pipe-bucket (buffered)
4632N/A Message-ID: <3C36ADAF.60601@cnet.com>
4632N/A * Try to get libtool inter-library dependency code working on AIX.
4632N/A Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
4632N/A Justin says: If we get it working on AIX, we can enable this
4632N/A on all platforms and clean up our build system
4632N/A Jeff says: I thought I tested a patch for you sometime in
4632N/A January that you were going to commit within a few
4632N/A * Handling of %2f in URIs. Currently both 1.3 and 2.0
4632N/A completely disallow %2f in the request URI path (see
4632N/A through in the query string, however. Roy says the
4632N/A original reason for disallowing it, from five years ago,
4632N/A was to protect CGI scripts that applied PATH_INFO to
4632N/A a filesystem location and which might be tricked by
4632N/A ..%2f..%2f(...). We *should* allow path-info of the
4632N/A Since we've revamped a lot of our processing of path
4632N/A segments, it would be nice to allow this, or at least
4632N/A allow it conditionally with a directive.
4632N/A * FreeBSD, threads, and worker MPM. All seems to work fine
4632N/A if you only have one worker process with many threads. Add
4632N/A a second worker process and the accept lock seems to be
4632N/A lost. This might be an APR issue with how it deals with
4632N/A the child_init hook (
i.e. the fcntl lock needs to be resynced).
4632N/A More examination and analysis is required.
4632N/A Status: This has also been reported on Cygwin.
4632N/A Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
4632N/A Justin says: So, FreeBSD-CURRENT and Cywin have the same
4632N/A problem. Yum. If another platform has this
4632N/A with worker, this becomes a showstopper.
4632N/A Aaron says: I spent some time disecting this and have come to
4632N/A the conclusion that it is not a problem in the worker MPM
4632N/A (or at least, it is not isolated to a problem in worker).
4632N/A I'll list some of the problems I'm seeing in case someone
4632N/A else wants to pick up where I've left off:
4632N/A - Delivery of just about any signal to one of the child
4632N/A processes will send it into an infinite loop as well.
4632N/A - Even though the parent is spinning out of control,
4632N/A at first the child or children will appear to work
4632N/A properly. At times it is possible to get it into a state,
4632N/A however, where a request will hang until another concurrent
4632N/A request "kicks" the first, at which point the second will
4632N/A hang. My theory is that this has to do with the
4632N/A pthread_cond_*() implementation in FreeBSD, but it's still
4632N/A possible that it is in APR.
4632N/A Justin adds: Oh, FreeBSD threads are implemented entirely with
4632N/A select()/poll()/longjmp(). Welcome to the nightmare.
4632N/A So, that means a ktrace output also has the thread
4632N/A scheduling internals in it (since it is all the same to
4632N/A the kernel). Which makes it hard to distinguish between
4632N/A our select() calls and their select() calls.
4632N/A *bangs head on wall repeatedly* But, some of the libc_r
4632N/A files have a DBG_MSG #define. This is moderately helpful
4632N/A when used with -DNO_DETACH. The kernel scheduler isn't
4632N/A waking up the threads on a select(). Yum. And, I bet
4632N/A those decrementing select calls have to do with the
4632N/A scheduler. Time to brush up on our OS fundamentals.
4632N/A * There is increasing demand from module writers for an API
4632N/A that will allow them to control the server � la apachectl.
4632N/A Reasons include sole-function servers that need to die if
4632N/A an external dependency (
e.g., a database) fails, et cetera.
4632N/A Perhaps something in the (ever more abused) scoreboard?
4632N/A rbb: I don't believe the scoreboard is the correct mechanism
4632N/A for this. We already have a pipe that goes between parent
4632N/A and child for graceful shutdown events, along with an API that
4632N/A can be used to send a message down that pipe. In threaded MPMs,
4632N/A it is easy enough to make that one pipe be used for graceful
4632N/A and graceless events, and it is also easy to open that pipe
4632N/A to both parent and child for writing. Then we just need to
4632N/A figure out how to do graceless on non-threaded MPMs.
4632N/A * Allow the DocumentRoot directive within <Location > scopes? This
4632N/A and in-your-face.) DocumentRoot unset would be accepted [and would
4632N/A not permit content to be served, only virtual resources such as
4632N/A server-info or server-status.
4632N/A This proposed change would _not_ depricate Alias.
4632N/A * Win32: Rotatelogs sometimes is not terminated when Apache
4632N/A goes down hard. FirstBill was looking at possibly tracking the
4632N/A child's-child processes in the parent process.
4632N/A OtherBill asks, wasn't this fixed?
4632N/A stoddard: Not fixed. Shared scoreboard might offer a good
4632N/A way for the parent to keep track of 'other child' processes
4632N/A and whack them if the child goes down.
4632N/A * Win32: Add a simple hold console open patch (wait for close or
4632N/A the ESC key, with a nice message) if the server died a bad
4632N/A death (non-zero exit code) in console mode.
4632N/A Resolution: bring forward same ugly hacks from 1.3.13-.20
4632N/A * Port of mod_ssl to Apache 2.0:
4632N/A (2) Enabling the various SSL caching mechanisms (shmcb, shmht)
4632N/A (3) Enabling SSL extentions
4632N/A (4) Trying to seperate the https filter logic from mod_ssl -
4632N/A This is to facilitate other modules that wish to use the https
4632N/A filter or the mod_ssl logic or both as required.
4632N/A Justin: mod_ssl filter logic is redone, so that should be fine.
4632N/A Madhu has submitted a patch for SSL caching - however, I
4632N/A am -0 on that patch as I *think* we could implement the
4632N/A shared memory another way that is much cleaner (
i.e. 4632N/A treat shmem directly as a dbm via APR routines). Justin
4632N/A also thinks that the https filter logic may be sufficiently
4632N/A decoupled now, but isn't really sure.
4632N/A * Performance & Debug: Eliminate most (and perhaps all) of the
4632N/A light weight memory management functions that allow freeing
4632N/A memory (putting it back into a memory pool) when it is no
4632N/A longer needed. Enabling simple debugging features like guard
4632N/A bands, double free detection, etc. would be cool but certainly
4632N/A Status: Cliff started to implement this using SMS as has
4632N/A been discussed at length for months, but since
4632N/A SMS is not being used anywhere else in the server,
4632N/A several people expressed the opinion that we should
4632N/A get rid of it entirely, meaning that the buckets
4632N/A need their own memory management (free list) functions.
4632N/A Cliff will implement that this weekend so we at least
4632N/A * Eliminate unnecessary creation of pipes in mod_cgid
4632N/A Status: Ken asks, didn't Jeff fix this when he fixed the queue
4632N/A * Platforms that do not support fork (primarily Win32 and AS/400)
4632N/A Architect start-up code that avoids initializing all the modules
4632N/A in the parent process on platforms that do not support fork.
4632N/A would eliminate some code in the Win32 branch that essentially
4632N/A * There are still a number of places in the code where we are
4632N/A losing error status (
i.e. throwing away the error returned by a
4632N/A system call and replacing it with a generic error code)
4632N/A * Mass vhosting version of suEXEC.
4632N/A the dbmmanage employs the first-matched dbm format. This is not
4632N/A necessarily the library that Apache was built with. Aught to
4632N/A rewrite dbmmanage upon installation to bin/ with the proper library
4632N/A for predictable mod_auth_dbm administration.
4632N/A Questions; htdbm exists, time to kill dbmmanage, or does it remain
4632N/A useful as a perl dbm management example? If we keep it,
4632N/A do we address the issue above?
4632N/A Some additional items remaining:
4632N/A - case_preserved_filename stuff
4632N/A (use the new canonical name stuff?)
4632N/A - find a new home for ap_text(_header)
4632N/A - is it possible to remove the DAV: namespace stuff from util_xml?
4632N/A * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
4632N/A are a bit wonky. The function should probably be exposed as a utility
4632N/A function (such as ap_translate_url2fs() or ap_validate_fs_url() or
4632N/A something). Another approach would be a new hook phase after
4632N/A "translate" which would allow the module to munge what the
4632N/A translation has decided to do.
4632N/A Status: Greg +1 (volunteers), Ryan +1
4632N/A calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
4632N/A ap_sort_hooks() [to reduce the logic in main()]
4632N/A * read the config tree just once, and process N times (as necessary)
4632N/A * (possibly) use UUIDs in mod_unique_id
and/or mod_usertrack
4632N/A * (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
4632N/A into a VirtualHost container) to 2.0.
4632N/A * callers of ap_run_create_request() should check the return value
4632N/A for failure (Doug volunteers)
4632N/A * Win32: Get Apache working on Windows 95/98. The following work
4632N/A (at least) needs to be done:
4632N/A - Document warning that OSR2 is required (for Crypt functions, in
4632N/A rand.c, at least.) This could be resolved with an SSL library, or
4632N/A randomization in APR itself.
4632N/A actually works) and add in a splash of Win9x service code.
4632N/A * In order to use a DSO version of mod_ssl we have to link with
4632N/A -lssl and -lcrypto. A workaround is in place right now where the
4632N/A entire EXTRA_LIBS macro is being appended to the objects list, but
4632N/A this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT
4632N/A autoconf function or come up with some other autoconf checks to
4632N/A search for libssl and libcrypto and properly add them to mod_ssl's
4632N/A * Fix the worker MPM to use POD to kill child processes instead
4632N/A of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
4632N/A * mod_cache: handle cache_control: no_cache "field_name" to enable
4632N/A cacheing the response w/o header "field_name"
4632N/APRs that have been suspended forever waiting for someone to
4632N/Aput them into 'the next release':

4632N/A No module specific data hook for per-connection data
4632N/A no way to set global quality-of-source (qs) coneg values
4632N/A Accessing URL through proxy server corrupts data.
4632N/A Some anonymous FTP URLs ask for authentication
4632N/A New ErrorDocumentMatch directive
4632N/A Need to be able to override shebang line to make CGI scripts
4632N/A "Files" and "FilesMatch" regexp does not recognize bang as
4632N/A Please allow CGI env variables (QUERY_STRING, ...) to be logged
4632N/A Suggestion for better handling of Last-modified headers
4632N/A mod_cgi prevents handling of OPTIONS requests
4632N/A [PATCH] install as win32 service with domain account
4632N/A Status: Cannot accept password-as-arg, we should prompt the
4632N/A user when -k install/-k config with a user argument.
4632N/A AllowOverride should have a 'CheckNone' and 'AllowNone' argument
4632N/AOther bugs that need fixing:
4632N/A * MaxRequestsPerChild measures connections, not requests.
4632N/A Until someone has a better way, we'll probably just rename it
4632N/A * Regex containers don't work in an intutive way
4632N/A Status: No one has come up with an efficient way to fix this
4632N/A behavior. Dean has suggested getting rid of regex containers
4632N/A OtherBill suggests: We at least seem to agree on eliminating
4632N/A the <Container ~ foo> forms, and using only
4632N/A <ContainerMatch foo> semantics.
4632N/A * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
4632N/A sigwaiting thread. We need to work around this, perhaps unless
4632N/A there is hope soon for a fixed glibc.
4632N/A needed. Apache 1.3 just never stashed "multipart" into
4632N/A r->content_type. We should probably follow suit since the
4632N/A byterange stuff doesn't want the rest of the code to see the
4632N/A multipart content-type; the other code should still think it is
4632N/A dealing with the <orig_ct> stuff.
4632N/A Status: Greg volunteers to investigate (esp. since he was most
4632N/A likely the one to break it :-)
4632N/AOther features that need writing:
4632N/A * Finish infrastructure in core for async MPMs
4632N/A * TODO in source -- just do an egrep on "TODO" and see what's there
4632N/A * Jon Travis's <jtravis@covalent.net> patch to deal with thread-safe
4632N/A issues with inet_ntoa. See message <20001201163220.A12827@covalent.net>
4632N/A Status: This is being set aside until the IPv6 work is finished
4632N/A so that we know exactly what is required.
4632N/A * Martin Sojka <msojka@gmx.de>'s patch to add error reporting for failed
4632N/A htpasswd actions due to a full /tmp volume (other programs may have
4632N/A * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
4632N/A Status: These were written for 1.3, and are awaiting a port to
4632N/A * Jim Winstead's <jimw@trainedmonkey.com> patch to add CookieDomain and
4632N/A other small mod_usertrack features
4632N/A * Dan Rench's <drench@xnet.com> patch to add allow the errmsg and timefmt
4632N/A of SSI's to be modified in the config file. Patch is available in
4632N/A * Which MPMs will be included with Apache 2.0?
