Not yet added to the default build, but curious if they build and run.
mod_deflate tested with both zlib 1.1.3/1.1.4, unpacked in srclib/zlib/.
Zlib only seems to have .dll builds, not very efficient when a single
binary is built against sources, so we compile the appropriate sources.
Your mileage may vary.
I just posted a few bug fixes that need to go into the worker MPM, so
I'm -1 here until those are fixed. I also think we need to do a lot more
load/soak/burn testing on worker before we switch it to be the default.
(and maybe by that time we'll have a better candidate for the hybrid
MP/MT MPM).
During the 1.3->2.0 migragrion; ab its #defined VERSION own string was replaced
by that of the base server distribution it sits in. Propably by accident.
This is propably not a good idea - as ideally one would like to be able to compare
ab runs as much as possible - even across releases of apache 2.0 - assuming ab or
the dependent APR has not changed (note to self: we do not track APR in our version
structure). This commit decouples the version strings for now. Though the actual
value may be nicely confusing.
Fix suexec invocations from userdir - the ~ was not being prepended to the
uid per our convention. Therefore, bad things would happen (like we
wouldn't cd to the right directory).
Add a flag to the ap_unix_identity_t structure to indicate if we are in
a userdir - if so, prefix the ~.
(Modified by Justin, but Colm's patch pointed me in the right direction.)
Since UserDir is a raw argument, our config system allows it to be blank.
To save us all the hassle, just flat out reject this silliness. We could
treat blank as ".", but let the user shoot themselves in the foot
explicitly (and don't give them any ideas on how to do it).
We must always use case-insensitive comparisons in mod_mime even if
our platform is not "case-blind." This matches 1.3 behavior and our
docs say that the extension argument is case-insensitive anyway.
This is case where the code fix is easier than the doc fix. =)

Get proxy protocol modules to build on OS/2. This adds the mod_proxy dll's
import library to the link, making the public symbols in it available to the
protocol modules at build time.
Major improvement in concurrent processing for AB:
- Enable non-blocking connects.
- Prevent quasi-blocking mode apr_recv (which would prevent AB from
multiplexing over the entire descriptor set).
- Catch other fatal apr_recv() errors.

A bug affecting any platform that had pre-lstat'ed the file or directory
in question. We neglected to clear the FINFO_LINK bit that told us this
was lstat()ed, but also causes stat() to follow an lstat() approach.

Clarify the remaining problems with Range: headers. The seg faults went away
when we changed ap_send_error_response to get rid of resource filters.
This was triggered because we generate a lot of invalid 416 responses for SSI.
That happens because the complete length of the entity body (response) isn't
known accurately until after the C/L filter runs. That's C/L's job, after all.
Flipping the order of the byterange and C/L filters fixes the invalid
Content-Range headers and 416's. But then the Content-Length header contains
the full length, rather than the sum of the returned ranges. That's wrong, but
doesn't seem too hard to fix.

Added the APLOG_TOCLIENT flag to ap_log_rerror() to

Prior to this change, ap_log_rerror() always sent warning

the server to send a warning message to the client that contained
the full path to the CGI script. This could be considered a
minor security exposure.

Fix subreqs with non-defined Content-Types being served improperly.
If we do not know a C-T for a subreq, we *must* propogate that
non-knowledge upwards to the main request.
Previously, if you used a DirectoryIndex with a file without a C-T (say
.shtml without AddType), the r->content_type will be kept as
httpd/unix-directory when we promoted the subreq in mod_dir. Since there
would be no handler on this file, ap_invoke_handler (config.c:355) would
set the handler to be httpd/unix-directory (which was the old C-T of the
dir). This would then trigger the handler to become httpd/unix-directory.
mod_autoindex would then try to serve the request. But, the filename
was propogated upwards by mod_dir's DirectoryIndex via
internal_fast_redirect - it would then return a 403 trying to generate a
mod_autoindex page for a file.
Now, we will use ap_default_type() which is correct.

Another experimental MPM derived from worker:
The threadpool MPM implements Aaron Bannert's "time-space tradeoff"
design managing idle workers. Rather than putting accepted connections
into a queue, the threadpool MPM keeps idle worker threads in a stack.
Its dedicated listener thread retrieves an idle worker from the stack
before accepting a connection. If there are no idle workers, the
listener blocks until a worker becomes available before doing an accept.
In many ways, threadpool is also a variant of leader/follower. They
both maintain a stack of idle threads. The difference is that threadpool
has a dedicated listener thread, and leader/follower rotates the listening
responsibility among its worker threads. In my initial testing, the
leader/follower MPM performs very well on multiprocessor Solaris 8 when
listening on a single port, but poorly when listening on multiple ports.
(I don't know why this is happening. What I've found so far is that
when you add a poll on the listen socket(s) before the accept in the
leader/follower MPM, all the socket-related syscalls in the httpd get
slower. My hypothesis is that the thread scheduler is making an optimal
decision about where (on what CPU) to run the newly awakened thread if
its first syscall is an accept, and a nonoptimal decision if its first
syscall is a poll.) The threadpool MPM performs better with multiple
listener ports, and in my testing so far it looks competitive with
leader/follower when running with a single listener.
