CURRENT RELEASE NOTES: * Forward binary compatibility is expected of Apache 2.0.x releases, such that no MMN major number changes will occur. Such changes can only be made in the trunk. * All commits to branches/2.0.x must be reflected in SVN trunk, as well, if they apply. Logical progression is commit to trunk, get feedback and votes in STATUS, and then merge into branches/2.0.x. RELEASE SHOWSTOPPERS: PATCHES TO BACKPORT FROM TRUNK: [ please place SVN revisions from trunk here, so it is easy to identify exactly what the proposed changes are! ] [ please append new backports at the end of this list not the top. ] *) several changes to improve logging of connection-oriented errors, including ap_log_cerror() API (needs minor bump in addition to changes below) http://cvs.apache.org/viewcvs.cgi/httpd-2.0/server/core.c?r1=1.289&r2=1.291 http://cvs.apache.org/viewcvs.cgi/httpd-2.0/server/log.c?r1=1.150&r2=1.151 http://cvs.apache.org/viewcvs.cgi/httpd-2.0/include/http_log.h?r1=1.46&r2=1.48 +1: trawick, stoddard -0: wrowe; seems this (valid) improvement would encourage non-compatible mods. *) mod_headers: Support {...}s tag for SSL variable lookup. http://www.apache.org/~jorton/mod_headers-2.0-ssl.diff +1: jorton, trawick nd: two comments: (1) is the use of APR_ASCII_* ebcdic-safe? I.e. shouldn't we use the native chars here and it will be converted later? (I'm not sure) jorton: I have no idea, let an EBCDIC-er complain if it breaks? trawick: seems that '\r' and '\n' are the better chars to check for; this is not raw data read from the network (or directly from SSL) but instead it is either protocol data that has already been converted to the native charset or it is other data which was created inside the server in the native charset (2) I'd put out (null) only if val is NULL, not if it's empty. jorton: ssl_var_lookup() returns "" in place of NULL, that was really a deliberate choice... but maybe you're right. *) mod_cgi: Added API call and overload of detached field in cgi_exec_info_t structure to support loading in current or new address space for CGIs. The patch change how NetWare use cmdtype for processes. It was made necessary by changes done to log.c r1.145. The HTTP and the APR patches are available at: +1: jjclar, bnicholes, trawick jerenkrantz: I'm confused as to the status of this backport. trawick: Somebody commits the APR 0.9 patch, then: do we have to wait for later APR 0.x release before putting calls to apr_procattr_addrspace_set() into httpd-2.0.x, or do we go ahead and introduce the prerequisite? *) mod_actions: Regression from 1.3: the file referred to must exist. Solve this by introducing the "virtual" modifier to the Action directive. PR 28553. modules/mappers/mod_actions.c: r1.32, r1.34 jerenkrantz: Icky side-effect of the *t == '0' check. +1: nd, jerenkrantz, wrowe, jim -0: by rbb (inconsistent to 1.3, discussion on dev@) nd: I'm going to reverse the default jerenkrantz, striker: I'm confused as to the status of this backport. *) mod_log_config: Cleanup log_header_out function to allow multiple headers like Set-Cookie to be logged properly. PR 27787 (2.0 + 1.3) modules/loggers/mod_log_config.c: r1.116 jerenkrantz asks: Isn't this what apr_table_merge is for? nd replies: yep. But cookies won't be merged, because browsers don't support it. jerenkrantz: Couldn't we copy the table and merge the values somehow? This just seems like a lot of code to duplicate what we have already. *shrug* Regardless, patch looks okay... +1: nd, jerenkrantz * Rewrite how proxy sends its request to allow input bodies to morph the request bodies. Previously, if an input filter changed the request body, the original C-L would be sent which would be incorrect. Due to HTTP compliance, we must either send the body T-E: chunked or include a C-L for the request body. Connection: Close is not an option. A newer version of this fix that acts even better (spools to disk) has been committed to trunk. The equivalent patch for 2.0.x is at: http://www.apache.org/~trawick/20reqbody.txt +1: trawick, jerenkrantz, +1 Previous votes (before trawick's recent 2.1 commits): +1: stoddard, striker, jim -1: brianp (we need a more robust solution than what's in 2.1 right now), * support/check_forensic: Fix tempfile usage svn rev 125495, 126224 jerenkrantz says: r126224 fixes brokenness with r125495 on Solaris. +1: thommay, jerenkrantz, trawick trawick: "which" isn't portable; I've suggested a work-around on dev@ jorton said: NetBSD's which isn't sufficient either. jerenkrantz: Since it's not in the critical path (and depends on mod_log_forensic), I think it's still worth it to backport it as-is. For the one or two platforms that don't like which, they can write their own version of the script. * Win32: Move call to mpm_service_install to the rewrite_args hook from the post_config hook. http://svn.apache.org/viewcvs?view=rev&rev=154319 +1: stoddard, striker, wrowe (as corrected in subsequent patches) * don't propagate input headers describing a body to a GET subrequest with no body http://svn.apache.org/viewcvs?view=rev&rev=158798 http://svn.apache.org/viewcvs?view=rev&rev=159410 http://svn.apache.org/viewcvs?view=rev&rev=160573 +1: gregames -1: jerenkrantz (read_length isn't a sufficient check to see if a body is present in the request; presence of T-E and C-L in the headers is the correct flag.) +/-0: wrowe (this has a negative impact on modules who wish to 'inspect' the headers, e.g. an xml transformation affected by the query string or request POST args. The right solution is adopt apreq, providing an API for filters to participate in POST bodies.) gregames: done in rev 160573 * mod_version: New Module, Backport from trunk. Requires Minor MMN Bump. http://svn.apache.org/repos/asf/httpd/httpd/branches/mod_version_for_2.0.x +1: pquerna Votes from before the integration branch: +1: jerenkrantz, wrowe (trivial, would even be cool in 1.3) *) Provide TLS/SSL upgrade functionality in mod_ssl allowing an unsecure connection to be upgraded to a secure connection upon request by the client. The full patch file is available at http://www.apache.org/~bnicholes/ as well as a test client tlsupgrade.c.

They are supposed to be set in stone. -1: wrowe: agrees with jerenkrantz, further realized that this major change in APR 1.0 caused -every- apr-util linked app to have the ldap sdk (openldap etc) linked in, and our --static-support stuff is horribly broken by this change. Not that it's wrong, we need to look at making it slightly more dynamic for those apps that don't touch ldap. *) Add load balancer support to the scoreboard in preparation for load balancing support in mod_proxy. include/scoreboard.h: 1.52 server/scoreboard.c: 1.75 +0: minfrin: it makes sense for v2.1 or v2.2 -0: nd, jerenkrantz nd: -0 as in "it should be considered as a 2.1 feature". If the modified structures are public (are they?), I'm just -1. jerenkrantz: Sounds like a good 2.1 feature... -1: wrowe (make this a private score to the module and you would be fine; we don't need to keep overloading a single scoreboard.) *) mod_ssl: Remove some unused functions (after CAN-2004-0488 fix is applied) http://cvs.apache.org/viewcvs.cgi/httpd-2.0/modules/ssl/ssl_util.c?r1=1.46&r2=1.47 +1: jorton trawick: need changes to mod_ssl.h to remove prototypes for those removed functions 0: nd: IMHO that's a public API change then and not applicable for 2.0, just let 'em in -1: wrowe (as nd suggests, leave the dead horse in peace.) * Replace some of the mutex locking in the worker MPM with atomic operations for higher concurrency. server/mpm/worker/fdqueue.c 1.24, 1.25 +1: brianp, ianh, jjclar trawick: Doesn't this make Apache 2.0.next slower except when the right atomic operations are available/ implemented? (Due to under-the-covers mutex operations when the dummy atomics are used?) pquerna: Has anyone tested the performance differences for different platforms? At this point I would favour waiting for 2.2. -0: stoddard (at least until the performance implications are clarified) * Allow mod_dav to do weak entity comparison functions. modules/dav/main/util.c: r1.45 [ This one is under review. Don't merge. ] +1: * mod_negotiation: parse quality values independent from the current locale and level values as integers. PR 17564. (essentially: get a rid of atof()) (2.0 + 1.3) modules/mappers/mod_negotiation.c: r1.114 +1: nd We need to decide what happens with unparsable qvalues. RFC 2616 states that q defaults to 1. (see 14.1 - 14.4). So should wrong qvalues be returned as 1.0 or 0.0 (as atof() did)? 1.0: nd 0.0: jim (a default != an "errored" value) * Keep the same SSLMutex for the lifetime of the parent process (instead of having children using different mutexes and failing to lock the session cache across restarts.) New patch forthcoming - JimJag's changes make the merge ugly. +1: wrowe +1 (concept): jim (final vote when the patch is available) * Fix the SSLMutex config parser so that all 'mechanisms' can take a filename, even if ignored, and they are rooted to the full path to the server (except for posixsem locks). This allows a very cross-platform default:logs/ssl_mutex to be used everywhere. Also eliminates the '.pid' suffix so that the name given is the name. Allows Win32 and other non-unicies to use named locks. New patch forthcoming - JimJag's changes make the merge ugly. +1: wrowe +1 (concept): jim (final vote when the patch is available) * mod_ssl: Drop SSL_EXPERIMENTAL_ENGINE test in favor of testing for the ENGINE_init() function in config.m4, and use HAVE_ENGINE_INIT instead. wrowe notes that this feature is a noop until configured with SSLEngine. http://www.apache.org/~wrowe/have_engine_init.patch for a clean 2.0 patch. modules/ssl/README 1.40 modules/ssl/config.m4 1.14 modules/ssl/mod_ssl.c 1.79 modules/ssl/mod_ssl.h 1.135 modules/ssl/ssl_engine_config.c 1.78 modules/ssl/ssl_engine_init.c 1.113 modules/ssl/ssl_toolkit_compat.c 1.33 +0: wrowe {Pending research into how to get AC to use -lsockets et. al., shows breakage on Solaris which can't -lcrypto -lssl without the extra pkgconfig/openssl.pc Libs: * foo } * mod_ssl: fix a link failure when the openssl-engine libraries are present but the engine headers are missing. modules/ssl/mod_ssl.c: r1.87 modules/ssl/mod_ssl.h: r1.139 modules/ssl/ssl_engine_config.c: r1.82 PREREQ: Blow away of SSL_EXPERIMENTAL_ENGINE (see above) +1: jwoolley, trawick, jim, jerenkrantz * When UseCanonicalName is set to OFF, allow ap_get_server_port to check r->connection->local_addr->port before defaulting to server->port or ap_default_port() server/core.c r1.247 +1: bnicholes, jim, wrowe 0: nd, jerenkrantz nd: can the local_addr->port ever be 0? bnicholes response: I couldn't tell you for sure if local_addr->port could be 0. But it makes sense that if it were then Apache wouldn't be listening on any port so it wouldn't matter anyway. nd replies: But if it can't be 0 the alternatives thereafter make no sense anymore, right? jim proposes: UseCanonicalName Client directive which implements this, keeping UseCanonicalName Off "as is". * ThreadStackSize for Win32 and threaded MPMs trawick will eventually put together a patch for httpd 2.0.next +1 concept: trawick, nd, stoddard, wrowe CURRENT VOTES: * Promote mod_ldap and mod_auth_ldap from experimental to non experimental status. +1: bnicholes, wrowe +0: minfrin (wait till the last cache bugs are ironed out) -1: jerenkrantz * httpd-std.conf and friends; a) httpd-std.conf should be tailored by install (from src or binbuild) even if user has existing httpd.conf +1: trawick, slive, gregames, ianh, Ken, wrowe, jwoolley, jim, nd, erikabele wrowe - prefer httpd.default.conf to avoid ambiguity with cvs, note that win32 installer creates just that file (.default.conf rather than .conf.default so that win32 can recognize .conf files as text configuration files.) b) tailored httpd-std.conf should be copied by install to sysconfdir/examples -0: striker c) tailored httpd-std.conf should be installed to sysconfdir/examples or manualdir/exampleconf/ +1: slive, trawick, Ken, nd (prefer the latter), erikabele d) tailored httpd-std.conf should be installed as httpd-std-.conf. +1: striker e) Installing a set of default config files when upgrading a server doesn't make ANY sense at all. +1: ianh - medium/big sites don't use 'standard config' anyway, as it usually needs major customizations -1: Ken, wrowe, jwoolley, jim, nd, erikabele wrowe - diff is wonderful when comparing old/new default configs, even for customized sites that ianh mentions jim - it makes sense assuming that the default configs include the updated directives and inline comments that explain the changes and make the 'diff' more useful. * If the parent process dies, should the remaining child processes "gracefully" self-terminate. Or maybe we should make it a runtime option, or have a concept of 2 parent processes (one being a "hot spare"). See: Message-ID: <3C58232C.FE91F19F@Golux.Com> Self-destruct: Ken, Martin Not self-destruct: BrianP, Ian, Cliff, BillS Make it runtime configurable: Aaron, Justin, wrowe, rederpj, jim, nd /* The below was a concept on *how* to handle the problem */ Have 2 parents: +1: jim -1: Justin, wrowe, rederpj, nd +0: Martin (while standing by, could it do something useful?) * Make the worker MPM the default MPM for threaded Unix boxes. +1: Justin, Ian, Cliff, BillS, striker +0: BrianP, Aaron (mutex contention is looking better with the latest code, let's continue tuning and testing), rederpj, jim -0: Lars, wrowe (let's make this defacto for the 2.2 release.), nd (for 2.0) RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP: * 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. OtherBill offers that this is a SERIOUS problem. We do not sort correctly by the ordering arguments passed to the register hook functions. This was proven when I reordered the open_logs hook to attempt to open the error logs prior to the access logs. Possibly the entire sorting code needs to be refactored. * pipes deadlock on all platforms with limited pipe buffers (e.g. both Linux and Win32, as opposed to only Win32 on 1.3). The right solution is either GStein's proposal for a "CGI Brigade", or OtherBill's proposal for "Poll Buckets" for "Polling Filter Chains". Or perhaps both :-) * All handlers should always send content down even if r->header_only is set. If not, it means that the HEAD requests don't generate the same headers as a GET which is wrong. * HP/UX 10.20: compile breakage in APR. Looks like it should be easy to fix, probably just some extraneous #include's that are fouling things up. PR: 9457 Jeff: See my reply and patch in the PR (and previous commit to stop using "pipe" as a field name). If patch is committed, we should be okay. I'll wait to see if the user tests the patch. Update by Jeff 20020722: I got an account on HP 10.20. It looks like some of the APR thread detection is screwed up. If we find pthread.h but we can't compile the pthread test program we still think we can use threads. For that reason, the patch I posted to the PR won't work as-is since a failed compile of the test program means nothing. * exec cmd and suexec arg-passing enhancements Status: Patches proposed Message-ID: <20020526041748.A29148@prodigy.Redbrick.DCU.IE> (see the "proc.patch" and "suexec-shell.patch" links in this message) * The 2.0.36 worker MPM graceless shutdown changes work but are a bit clunky on some platforms; eg, on Linux, the loop to join each worker thread seems to hang, and the parent ends up killing off the child with SIGKILL. But at least it shuts down. * --enable-mods-shared="foo1 foo2" is busted on Darwin. Pier posted a patch (Message-ID: ). * We do not properly substitute the prefix-variables in the configuration scripts or generated-configs. (i.e. if sysconfdir is etc, httpd-std.conf points to conf.) * If any request gets through ap_process_request_internal() and is scheduled to be served by the core handler, without a flag that this r->filename was tested by dir/file_walk, we need to 500 at the very end of the ap_process_request_internal() processing so sub_req-esters know this request cannot be run. 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> [Deleted comments regarding the ap_run_handler phase, as irrelevant as BillS points out that "common case will be caught in default_handler already (with the r->finfo.filetype == 0 check)" and the issue is detecting this -before- we try to run the req.] gregames says: can this happen somehow without a broken module being involved? If not, why waste cycles trying to defend against potential broken modules? It seems futile. wrowe counters: no, it shouldn't happen unless the module is broken. But the right answer is to fail the request up-front in dir/file walk if the path was entirely invalid; and we can't do that either UNTIL 2.1 or we break modules that haven't hooked map_to_storage. * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me how the Perchild MPM should be re-written. It hasn't worked correctly since filters were added because it wasn't possible to get the content that had already been written and the socket at the same time. This mode lets us do that, so the MPM can be fixed. * htpasswd blindly processes the file you give it, and does no sanity checking before totally corrupting whatever file it was you thought you had. It should check the input file and bail if it finds non-comment lines that do not contain exactly 1 ':' character. Message-ID: <20020217150457.A31632@clove.org> * Can a static httpd be built reliably? Message-ID: <20020207142751.T31582@clove.org> * [Ken] Test suite failures: o worker is also failing some of the 'cgi' subtests (see ): Justin says: "Worker should be fine and passes httpd-test here. I think it's a perl or a httpd-test problem." * Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be removed if possible. Message-ID: Jeff wonders if we still care about this. It is no longer an API issue but simply an extra trip through the brigade. * 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 a nice solution. See ROADMAP. * Get perchild to work on platforms other than Linux. This will require a portable mechanism to pass data and file/socket descriptors between vhost child groups. An API was proposed on dev@apr: Message-ID: <20020111115006.K1529@clove.org> * Try to get libtool inter-library dependency code working on AIX. Message-ID: 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. OtherBill adds that %2f as the SECOND character of a multibyte sequence causes the request to fail! This happens notably in the ja-jis encoding. OtherBill is -0.5 for even considering this until 2.2 because it removes some protection we provided to third party modules that would mysteriously 'evaporate', exposing potential holes in security. Putting this change into 2.1 development now (with strong warnings!) will give authors a chance to vet their code. * There is increasing demand from module writers for an API that will allow them to control the server à 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? On the other hand, 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. * 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. stoddard: 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. Other thoughts on walking the process chain using the NT kernel have also been proposed on APR. * Eliminate unnecessary creation of pipes in mod_cgid * Combine log_child and piped_log_spawn. Clean up http_log.c. Common logging API. * 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? March discussion summary; we are missing group support. With that added to trunk, this script will go away. It will remain in 2.0 based on our versioning approach. * 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) * 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) OtherBill adds that the 'good' solution of three passes against the config tree within one read is the better solution, but breaks many modules. Best left for 2.2? -0.5: OtherBill * (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: - 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. * Fix the worker MPM to use POD to kill child processes instead of ap_os_killpg, regardless of how they should die. * Scoreboard structures could be changed in the future such that proper alignment is not maintained, leading to segfaults on some systems. Cliff posted a patch to deal with this issue but later recanted. See this message to dev@apr.apache.org: Message-ID: TODO ISSUES REMAINING IN MOD_SSL: * 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. * SSL renegotiations in combination with POST request * Port or dispose all code inside #if 0...#endif blocks that remain from the porting effort. * Do we need SSL_set_read_ahead()? * the ssl_expr api is NOT THREAD SAFE. race conditions exist: -in ssl_expr_comp() if SSLRequire is used in .htaccess (ssl_expr_info is global) -is ssl_expr_eval() if there is an error (ssl_expr_error is global) * SSLRequire directive (parsing of) leaks memory * Diffie-Hellman-Parameters for temporary keys are hardcoded in ssl_engine_dh.c, while the comment in ssl_engine_kernel.c says: "it is suggested that keys be changed daily or every 500 transactions, and more often if possible." * ssl_var_lookup could be rewritten to be MUCH faster * CRL callback should be pluggable * session cache store should be pluggable * init functions should return status code rather than ssl_die() * ssl_engine_pphrase.c needs to be reworked so it is generic enough to also decrypt proxy keys * the shmcb code should just align its memory segment rather than jumping through all the "safe" memcpy and memset hoops EXPERIMENTAL MODULES: mod_auth_ldap/util_ldap: * General stabilization and testing * Fix the shared memory cache PRs that have been suspended forever waiting for someone to put them into 'the next release': * documentation and Q&A PR#2221: Make online documentation search link back to my installation Status: PR#2906: Propose that Apache recommend $UNIQUE_ID for all "session id" algorithms Status: PR#2793: When will Apache support P3P?

Other bugs that need fixing: * ap_discard_request should be converted to use the bucket API directly rather than waste cycles copying buffers with the old API. * 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. OtherBill suggests: We at least seem to agree on eliminating the forms, and using only semantics. * 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 stuff.
