2a6c49cfaef5979a5a06098f3ce987cd76769409manoj * Windows NT port isn't done
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard Status: Bill is working on MPM and APR. 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.
2a6c49cfaef5979a5a06098f3ce987cd76769409manojRELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * Win32: Redirect stderr to the error log. This is tougher than it appears
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard because Apache for Windows now uses native file I/O libraries rather than
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard the CRT library. No problem redirecting native I/O STDERR to the error log.
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard However, we need to replace all the fprintf(stderr...) calls with something
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard that will write to the native stderr handle instead of the CRT stderr handle.
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard * Win32: Migrate the MPM over to use APR thread/process calls.
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
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard Status: Bill has prototype code (not reliable) in 1.3. Should be much
9c09943bad734ebd5c7cc10bd6d63b75c4c6e056stoddard cleaner with APR in 2.0.
aa1faea36e4ae357bc603a2337b6adc54f5daec1manoj * Switch to autoconf, et al. for configuration.
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.
d6b3cb141f0667101c1bca883ad15b383402c93bfielding * Areas where APRFile is being used need to be cleaned-up
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
d6b3cb141f0667101c1bca883ad15b383402c93bfielding * Odd comments in source (egrep for "ZZZ") need to be cleaned-up
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
