f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Complete HAVE_SENDFILE work. Need to add iovec head and tail pointers to

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel the iol sendfile API and make it work under Unix.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Status: code has been added to APR to support timing out pipes.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel This needs to be used in Apache now.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Status: Bill <stoddard@raleigh.ibm.com> is working on MPM and APR.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Remaining work:

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel 1. Add back ability to run Apache as a service

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel 2. Fix Win9* specific code in the winnt MPM

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel 3. Get the MPM working in multi process mode (one parent & one child)

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel 4. Test access logging with multiple threads. Will the native file I/O

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel calls serialize automagically like the CRT calls or do we need to

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel add region locking each time we write to the access/error logs?

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Current 2.0 code is not tested on many Unix platforms. Make 2.0

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel work on most, if not all the systems 1.3 did

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Status: Autoconf and APR will get us most of the way there.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * The module API is a weird combination of the old table and the new

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel hook system. Switch completely to the new hook system

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Status: Ben Laurie is working on this.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Modules. Which modules do not work yet, can we get a list?

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan FriedelRELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Clean the code. There are a lot of places we used APR but didn't

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel remove the hacks that were required for the cross-platform code in

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel 1.3. We need to make the code look like APR was supposed to be there.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Go throught the Bug DB and research the bugs marked "suspended". People

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel were told these would be considered for inclusion in Apache 2.0, it

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel would be nice to actually do so.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * Win32: Redirect stderr to the error log. This is tougher than it appears

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel because Apache for Windows now uses native file I/O libraries rather than

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel the CRT library. No problem redirecting native I/O STDERR to the error log.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel However, we need to replace all the fprintf(stderr...) calls with something

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel that will write to the native stderr handle instead of the CRT stderr handle.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel Bleh.

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel

f89940742f5d14dde79b69b98a414dd7b7f585c7Jan Friedel * 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.

Status: Bill <stoddard@raleigh.ibm.com> is working on this.

* Move I/O layering into APR.

* There are still a number of places in the code where we are loosing error

status (i.e. throwing away the error returned by a system call and replacing

it with a generic error code)

* APRize the stat function. CRT stat() is about 30% slower on Windows than

the equivalent native Windows call. The APR call should return the Unix

style stat structure, just to keep it familier.

* Implement reliable piped logs on Windows

Status: Bill <stoddard@raleigh.ibm.com> has prototype code (not reliable) in 1.3.

Should be much cleaner with APR in 2.0.

* Switch to autoconf, et al. for configuration.

* Use APR to get rid of more platform dependancies.

Status: Ryan Bloom <rbb@raleigh.ibm.com> is working on this.

* The connection status table is not very efficient. Also, very few stats

are exported to the connection status table (easy to fix), and mod_status

is ugly.

Other bugs that need fixing:

* 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.

* Areas where APRFile is being used need to be cleaned-up

* SIGSEGV on Linux seems to only kill a thread, not a whole process;

we need to work around this, probably by bouncing the signal to

the sigwait thread. But this will hurt debugability.

Other features that need writing:

* Finish infrastructure in core for async MPMs

Status: ?

* TODO in source -- just do an egrep on "TODO" and see what's there

* Odd comments in source (egrep for "ZZZ") need to be cleaned-up

* Work on other MPMs. Possible MPMs discussed or in progress include:

- Dean Gaudet's async MPM

Status: ?

- Zach Brown's <zab@zabbo.net> Linux siginfo MPM

Status: ?

Documentation that needs writing:

* The concept of MPMs, especially if we ship more than one MPM for a

given platform

* New directives in the various MPMs

* API documentation

Status: Ben Laurie has written some hooks documentation

(apache-2.0/htdocs/hooks.html)

* Changes since 1.3.9 can be more easily seen in the commitlog file

dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0

which includes some of Roy's comments when the changes were

committed in rough change-sets by purpose. Note that the commitlog

does not show the contents of new files until later.

Available Patches:

* Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve

performance

Status: These were written for 1.3, and are awaiting a port to

2.0

Open issues:

* What do we do about mod_proxy?

* Which MPMs will be included with Apache 2.0?

* Is conf/highperformance.conf-dist obsolete? It looks obsolete.
