2a6c49cfaef5979a5a06098f3ce987cd76769409manoj 2.0: In pre-alpha development
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Vague goal of an alpha or beta release in 1999. Commit-then-review
2a6c49cfaef5979a5a06098f3ce987cd76769409manojRELEASE SHOWSTOPPERS:
7ba24263a36323ecaf0685758f44001c0800d012stoddard * Complete HAVE_SENDFILE work. Need to add iovec head and tail pointers to
7ba24263a36323ecaf0685758f44001c0800d012stoddard the iol sendfile API and make it work under Unix.
7ba24263a36323ecaf0685758f44001c0800d012stoddard Status: Bill <stoddard@raleigh.ibm.com> is working on this
4065b438067f3f08d0bd98b31ac4085b581b931dstoddard * Pipes to CGI scripts are not being timed out
2739add8add66e21526ce27f83c2ae133d089070rbb Status: code has been added to APR to support timing out pipes.
2739add8add66e21526ce27f83c2ae133d089070rbb This needs to be used in Apache now.
211bf1d44f4653bf753a15740cd5ebbf330b6e93manoj * Put back resource limit code
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * Port mod_rewrite

2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * suEXEC doesn't work
369edcdd0a9c5516c61e736ec2a6fc8fb0d92fe2manoj Status: Manoj has posted an patch to fix this.
369edcdd0a9c5516c61e736ec2a6fc8fb0d92fe2manoj <19991103003605.A20612@samosa.mindspring.com>
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Windows NT port isn't done
7ba24263a36323ecaf0685758f44001c0800d012stoddard Status: Bill <stoddard@raleigh.ibm.com> is working on MPM and APR.
7ba24263a36323ecaf0685758f44001c0800d012stoddard Remaining work:
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard 1. Add back ability to run Apache as a service
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard 2. Fix Win9* specific code in the winnt MPM
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard 3. Get the MPM working in multi process mode (one parent & one child)
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard 4. Test access logging with multiple threads. Will the native file I/O
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard calls serialize automagically like the CRT calls or do we need to
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard add region locking each time we write to the access/error logs?
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Current 2.0 code is not tested on many Unix platforms. Make 2.0
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj work on most, if not all the systems 1.3 did
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj Status: Autoconf and APR will get us most of the way there.
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * The module API is a weird combination of the old table and the new
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj hook system. Switch completely to the new hook system
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj Status: Ben Laurie is working on this.
56ca30c968906053ae61acb218420667bb58d996rbb * Modules. Which modules do not work yet, can we get a list?
2a6c49cfaef5979a5a06098f3ce987cd76769409manojRELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
56ca30c968906053ae61acb218420667bb58d996rbb * Clean the code. There are a lot of places we used APR but didn't
56ca30c968906053ae61acb218420667bb58d996rbb remove the hacks that were required for the cross-platform code in
56ca30c968906053ae61acb218420667bb58d996rbb 1.3. We need to make the code look like APR was supposed to be there.
56ca30c968906053ae61acb218420667bb58d996rbb * Go throught the Bug DB and research the bugs marked "suspended". People
56ca30c968906053ae61acb218420667bb58d996rbb were told these would be considered for inclusion in Apache 2.0, it
56ca30c968906053ae61acb218420667bb58d996rbb would be nice to actually do so.
7ba24263a36323ecaf0685758f44001c0800d012stoddard * Win32: Migrate the MPM over to use APR thread/process calls. This would eliminate
7ba24263a36323ecaf0685758f44001c0800d012stoddard some code in the Win32 branch that essentially duplicates what is in APR.
7ba24263a36323ecaf0685758f44001c0800d012stoddard Status: Bill <stoddard@raleigh.ibm.com> is working on this.
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * Move I/O layering into APR.
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * There are still a number of places in the code where we are loosing error
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard status (i.e. throwing away the error returned by a system call and replacing
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard it with a generic error code)
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * APRize the stat function. CRT stat() is about 30% slower on Windows than
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard the equivalent native Windows call. The APR call should return the Unix
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard style stat structure, just to keep it familier.
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * Implement reliable piped logs on Windows
7ba24263a36323ecaf0685758f44001c0800d012stoddard Status: Bill <stoddard@raleigh.ibm.com> has prototype code (not reliable) in 1.3.
7ba24263a36323ecaf0685758f44001c0800d012stoddard Should be much cleaner with APR in 2.0.
aa1faea36e4ae357bc603a2337b6adc54f5daec1manoj * Switch to autoconf, et al. for configuration.
f03d292915be9977eaf74e9be7b0404aec226f84manoj Status: Manoj has placed an initial version into the 2.0
f03d292915be9977eaf74e9be7b0404aec226f84manoj repository. Todos include:
f03d292915be9977eaf74e9be7b0404aec226f84manoj - Support selection of modules (including MPMs; only Dexter
f03d292915be9977eaf74e9be7b0404aec226f84manoj works right now). Probably involved creating a directory for
f03d292915be9977eaf74e9be7b0404aec226f84manoj each module
f03d292915be9977eaf74e9be7b0404aec226f84manoj - "make install" and "make depend" should work
f03d292915be9977eaf74e9be7b0404aec226f84manoj - a tool to simplfy third-party module building should be
f03d292915be9977eaf74e9be7b0404aec226f84manoj written. Something like apxs
f03d292915be9977eaf74e9be7b0404aec226f84manoj - Add a lot more checks to satisfy the various platforms, e.g.
f03d292915be9977eaf74e9be7b0404aec226f84manoj for threading
aa1faea36e4ae357bc603a2337b6adc54f5daec1manoj * Use APR to get rid of more platform dependancies.
aa1faea36e4ae357bc603a2337b6adc54f5daec1manoj Status: Ryan Bloom <rbb@raleigh.ibm.com> is working on this.
302dc1f7b3feee23a91ad8f3cf3cb2edd95a557bmanoj * The connection status table is not very efficient. Also, very few stats
302dc1f7b3feee23a91ad8f3cf3cb2edd95a557bmanoj are exported to the connection status table (easy to fix), and mod_status
2a6c49cfaef5979a5a06098f3ce987cd76769409manojOther bugs that need fixing:
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * MaxRequestsPerChild measures connections, not requests.
d5defd5a0c5cdbaf74b85939484dc2b6c8317d19manoj Until someone has a better way, we'll probably just rename it
d5defd5a0c5cdbaf74b85939484dc2b6c8317d19manoj "MaxConnectionsPerChild".
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Regex containers don't work in an intutive way
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj Status: No one has come up with an efficient way to fix this
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj behavior. Dean has suggested getting rid of regex containers
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj completely.
d5defd5a0c5cdbaf74b85939484dc2b6c8317d19manoj * SIGSEGV on Linux seems to only kill a thread, not a whole process;
fbfdb4a45ff0e32dbfef0d414c8d75fe8aebcbb9manoj we need to work around this, probably by bouncing the signal to
fbfdb4a45ff0e32dbfef0d414c8d75fe8aebcbb9manoj the sigwait thread. But this will hurt debugability.
2a6c49cfaef5979a5a06098f3ce987cd76769409manojOther features that need writing:
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Finish infrastructure in core for async MPMs
dbf0c7bef06259486cd2748a2d0e82f27e099d6efielding * TODO in source -- just do an egrep on "TODO" and see what's there
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Work on other MPMs. Possible MPMs discussed or in progress include:
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj - Dean Gaudet's async MPM
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj - Zach Brown's <zab@zabbo.net> Linux siginfo MPM
2a6c49cfaef5979a5a06098f3ce987cd76769409manojDocumentation that needs writing:
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * The concept of MPMs, especially if we ship more than one MPM for a
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj given platform
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * New directives in the various MPMs
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * API documentation
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj Status: Ben Laurie has written some hooks documentation
d6b3cb141f0667101c1bca883ad15b383402c93bfielding * Changes since 1.3.9 can be more easily seen in the commitlog file
d6b3cb141f0667101c1bca883ad15b383402c93bfielding dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0
d6b3cb141f0667101c1bca883ad15b383402c93bfielding which includes some of Roy's comments when the changes were
d6b3cb141f0667101c1bca883ad15b383402c93bfielding committed in rough change-sets by purpose. Note that the commitlog
d6b3cb141f0667101c1bca883ad15b383402c93bfielding does not show the contents of new files until later.
