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 * The AddInputFilter and AddOutputFilter directives do not allow the administrator to remove or reorder filters. Once a filter is added in a container, it is present in any subcontainers. It can only be added to the filter chain after any filters specified in enclosing containers. * mod_dir should normally redirect ALL directory requests which do not include a trailing slash on the URI. However, if a "notes" flag is set (say, via BrowserMatch), this behavior will be disabled for non-GET requests. Status: Greg volunteers MsgId: <20010227104646.E2297@lyra.org> MsgId: <3A9C0097.9C83F07C@Golux.Com> * mod_negotiation will not serve a request when an early extention is understood, but a later extention is not. e.g. if the request index.html.bak is recieved, and negotition could find the file index.html.bak.en, it still won't be served because the ap-mime-exception-list will contain "index" and "bak", and the string "index.bak" doesn't match "index.html.bak". Need to review the ap-mime-exception-list component by component to be allow these cases. [This could be part of a patch to allow the name index.bak in the case above to match index.html.bak.en] * mod_negotiation needs a new option or directive, something like ForceLanguagePriority, to fall back to the LanguagePriority directive instead of returning a "no acceptable variant" error. * Usability: Sanitize the MPM config directives. MaxClients in the threaded MPM is totally misleading now as it has little to do with limiting the number of clients (it limits the number of child processes). Bill proposed nomenclature change to something like "StartWorkers, MaxWorkers, etc." that could apply to most all the MPMs (with some notable exceptions). Bill would be happy with changing MaxClients to MaxServers to make it agree with the operation of the StartServers directive. * configure --enable-mods-shared=most option has issues. Example: ./configure --enable-mods-shared=most This builds mod_headers as a DSO (good) but builds mod_mime as a compiled-in module (bad). RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP: * daedalus: mod_cgid and suexec have a problem co-existing. suexec sees a null command string sometimes. The problem happens when you access bugs.apache.org, then click on the "search the bug db" button. * 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. * 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 next step is to figure out how the old three configuration contexts (global, per-server, per-directory) can be ported to Apache 2.0 (especially the global context which has to survive server restarts RSE still does not know how to port). Then the remaining source files (which depend on the configuration contexts) which are still tagged with "-" in modules/ssl/README can be ported. One more thing to figure out is how and when mod_ssl can provide the interactive pass phrase dialog (in Apache 1.3 it used the first init round [where tty was still not detached] and skipped the second init round [where it was already detached]). Apache 2.0 requires (or already has?) an official hook where such tty-dialogs can be performed. RSE is on holiday until June 11th, 2001. After this he starts working on mod_ssl again and tries to make mod_ssl running inside Apache 2.0 by end of June. If anyone wants to help making mod_ssl running in the meantime, feel free to make your hands dirty inside modules/ssl/. Do whatever you think is appropriate to get it running. I've no objections of any kind, except: just do not remove any old functionality. Keep everything, even if it needs #if 0...endif wrapped to not make trouble for you. * Performance: Get the SINGLE_LISTEN_UNSERIALIZED_ACCEPT optimization working in threaded. prefork's new design for how to notice data on the pod should be sufficient. * mod_tls is very specific to OpenSSL. Make the API calls more generic to support other encryption libraries. * 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, David, et al have discussed using the blocks SMS for this. First step is to s/malloc/apr_sms_malloc/g, etc. We could then have a thread-private SMS that is pointed to by the conn_rec's or something so that all calls to the bucket create functions can pass in that SMS. No locks required. Should be fast... * 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: * 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. * 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." * 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 * APR-ize resolver stuff in mod_unique_id (Jeff volunteers) * callers of ap_run_create_request() should check the return value for failure (Doug volunteers) * when prefork bails out due to an initialization error in the detached process (e.g., mutex init failure), other children (cgid, at least) are left hanging around * 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.
