6f51bbc3054846e0c0a897d5f16ceba1726bebc6jerenkrantz * Win32: Get mod_auth_digest working under win32
6f51bbc3054846e0c0a897d5f16ceba1726bebc6jerenkrantz - APR_HAS_RANDOM should be defined on windows and there is a
6f51bbc3054846e0c0a897d5f16ceba1726bebc6jerenkrantz lib/apr/misc/win32/rand.c which is basically a copy of what
6f51bbc3054846e0c0a897d5f16ceba1726bebc6jerenkrantz mod_auth_digest used to use.
ff920f8ae37ba372801b67ea7c3d5bf1dfb55585dreid * Re-work configuration for top level Apache. Work should start with
ff920f8ae37ba372801b67ea7c3d5bf1dfb55585dreid trying to clean the autoconf stuff. If and only if this proves
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe impossible to do (very unlikely), autoconf should be removed and we
ff920f8ae37ba372801b67ea7c3d5bf1dfb55585dreid will roll our own config implementation.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe NOTE: When this is implemented, it would be really nice if the
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe default cgi module on Unix with a threaded MPM is the cgid
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe module. This should be override-able of course.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe Status: Jim Jagielski is looking into this.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * Fix SAFEREAD.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe see <Pine.LNX.4.21.0004101511380.7822-100000@twinlark.arctic.org>
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Put back resource limit code
ff920f8ae37ba372801b67ea7c3d5bf1dfb55585dreid * suEXEC doesn't work
a601d863bd772fefc4dc82a883589d8be6a44811wrowe Status: Manoj has posted an patch to fix this.
a601d863bd772fefc4dc82a883589d8be6a44811wrowe <19991103003605.A20612@samosa.mindspring.com>
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * Win32: Enable the Windows MPM to honor max_requests_per_child
a601d863bd772fefc4dc82a883589d8be6a44811wrowe Status: Bill will fix this.
a601d863bd772fefc4dc82a883589d8be6a44811wrowe * Win32: Get Apache working on Windows 95/98. The following work
a601d863bd772fefc4dc82a883589d8be6a44811wrowe (at least) needs to be done:
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe - winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe specific code that is still not in NT only code paths
a601d863bd772fefc4dc82a883589d8be6a44811wrowe - APR sendfile uses TransmitFile which is not available on
a601d863bd772fefc4dc82a883589d8be6a44811wrowe - ap_stat uses GetFileAttributeEx which is not available on
a601d863bd772fefc4dc82a883589d8be6a44811wrowe * Win32: Test access logging with multiple threads. Will the
a601d863bd772fefc4dc82a883589d8be6a44811wrowe native file I/O calls serialize automagically like the
a601d863bd772fefc4dc82a883589d8be6a44811wrowe CRT calls or do we need to add region locking each time
a601d863bd772fefc4dc82a883589d8be6a44811wrowe we access the logs?
a601d863bd772fefc4dc82a883589d8be6a44811wrowe * The handler hook needs to use the new registration system
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * We need a thread-safe resolver, at least on Unix.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe Status: The best known candidate would be something from
998a0c99bc22357406f359ace2f602c5d6e376c6wroweRELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * Build scripts do not recognise AIX 4.2.1 pthreads, so the
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe pthread MPMs will not build.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * the top-level configure.in appears to use $USE_MAINTAINER_MODE = yes
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe to set -Wall/etc. flags, and the APR configure.in appears to use
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe --with-debug. both seem like more of a hardwired pain compaired
bfae8a5d3c37df19dea49b411b109198c7e84a4fbrianp to the pre-2.0 method of setting EXTRA_CFLAGS.
bfae8a5d3c37df19dea49b411b109198c7e84a4fbrianp * Win32: Reuse accept socket after transmitfile/close
7dfb10a15cdfd48a23a9aa5713a2deb129821761wrowe This is not a bug, but would be nice to get this feature in
7dfb10a15cdfd48a23a9aa5713a2deb129821761wrowe before ship.
998a0c99bc22357406f359ace2f602c5d6e376c6wrowe * Win32: Enable the winnt MPM to use the new scoreboard API
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Win32: Graceful restart of a service is broken (code does shutdown then start)
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Platforms that do not support fork (primarily Win32 and AS/400)
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein Consider introducing HAVE_FORK feature macro. Architect start-up code
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein that avoids initializing all the modules in the parent process on
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein platforms that do not support fork.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Clean the code. There are a lot of places we used APR but didn't
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein remove the hacks that were required for the cross-platform code in
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein 1.3. We need to make the code look like APR was supposed to be there.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Go throught the 1.3 Bug DB and research the bugs marked "suspended".
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein People were told these would be considered for inclusion in Apache 2.0,
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein it would be nice to actually do so.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Win32: Migrate the MPM over to use APR thread/process calls. This
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe would eliminate some code in the Win32 branch that essentially
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe duplicates what is in APR.
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe Bill says we need a new procattr, APR_CREATE_SUSPENDED (or
29b927351fa38aca768d31d70116acd0a71ed415jerenkrantz something similar) to direct ap_create_process to create the
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein process suspended. We also need a call to wake up the suspended
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein process This may not be able to be implemented everywhere though.
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein * Move I/O layering into APR.
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein * There are still a number of places in the code where we are
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein loosing error status (i.e. throwing away the error returned by a
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein system call and replacing it with a generic error code)
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein * Win32: Implement reliable piped logs on Windows
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein * Switch to autoconf, et al. for configuration.
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein Status: Manoj has placed an initial version into the 2.0
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein repository. Todos include:
39d8628e74736d0bd8c4114d8e615dffa8fbbcf7gstein * Use APR to get rid of more platform dependancies.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein Status: Ryan Bloom <rbb@covalenet.net> is working on this.
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe * The connection status table is not very efficient. Also, very few stats
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe are exported to the connection status table (easy to fix), and mod_status
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Optimise the name-based <VirtualHost> implementation so that it uses
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein a hash table instead of a linear linked list scan.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Mass vhosting version of suEXEC.
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe * Provide a sane API for handling the request's environment variables.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * configuration option to use *DBM
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein Status: Greg +1 (volunteers)
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * add SDBM into src/lib/sdbm/ as a default/fallback DBM implementation.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein SDBM is used by Perl, mod_dav, mod_sssl, others for basic DBM support.
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe Status: Greg +1 (volunteers)
cdc56e100a8fa11e989d1633914502db1c8e0818wroweOther bugs that need fixing:
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe * MaxRequestsPerChild measures connections, not requests.
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe Until someone has a better way, we'll probably just rename it
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe "MaxConnectionsPerChild".
cdc56e100a8fa11e989d1633914502db1c8e0818wrowe * Regex containers don't work in an intutive way
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein Status: No one has come up with an efficient way to fix this
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein behavior. Dean has suggested getting rid of regex containers
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein completely.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein sigwaiting thread. We need to work around this, perhaps unless
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein there is hope soon for a fixed glibc.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gsteinOther features that need writing:
10a6f4803b893e9e77f5ad60ccb387ca1a15f84djerenkrantz * Finish infrastructure in core for async MPMs
10a6f4803b893e9e77f5ad60ccb387ca1a15f84djerenkrantz Status: post 2.0
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * TODO in source -- just do an egrep on "TODO" and see what's there
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gsteinDocumentation that needs writing:
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Mod_status docs are needed.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * The concept of MPMs, especially if we ship more than one MPM for a
10a6f4803b893e9e77f5ad60ccb387ca1a15f84djerenkrantz given platform
10a6f4803b893e9e77f5ad60ccb387ca1a15f84djerenkrantz * New directives in the various MPMs and appropriate links from
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein obsolete directives in core.html to the MPM documentation.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Revise manual/stopping.html and the last part of
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein manual/misc/perf-tuning.html to take account of the MPMs.
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * API documentation
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein Status: Ben Laurie has written some hooks documentation
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein * Changes since 1.3.9 can be more easily seen in the commitlog file
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0

27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein committed in rough change-sets by purpose. Note that the commitlog
27ddebab333df2a3d82b0f4ea63878d1d9f38ae8gstein does not show the contents of new files until later.
