the status code returned by a handler by updating the values of the filter
error macros and consolidating them in httpd.h

Using this basic framework, you can return SUSPENDED from an HTTP Handler,
and then register a callback that is invoked by the MPM at a later time.
This initial version only supports _timers_ as callbacks, but in the future I
would like to add things like wait for socket activity, on a socket specified by
the handler.
Once in a callback, It is then the responsibility of the callback fucntion
to finish the HTTP Request handling, but this alows you to do cool things like
a fully async proxy, COMET support, or even rate limiting.
To prove I'm not insane, I've inlcuded an example module, mod_dialup.
You can configure it like this:
<Location "/docs">
ModemStandard "V.32"
</Location>
And for static files inside that path, you will be rate limited to V.32 speeds,
aka 9.6 kilobits/second.
Does anyone besides Rüdiger read commit emails :-) ?
I know there are likely huge problems with this, but I would like to see how far
we can push the Event MPM, figure out what to do better, if there is anything,
and then really dive into the 3.0 development before ApacheCon.
* server/mpm/experimental/event/fdqueue.h:
(timer_event_t): New structure to hold timer events and callback functions.
* server/mpm/experimental/event/fdqueue.c
(ap_queue_empty): Modify to also look at Timer Ring.
(ap_queue_init): Initialize Timer Ring.
(ap_queue_push_timer): New function, pushes a timer event into the queue.
(ap_queue_pop_something): Renamed function, returns a timer event or
a socket/pool for a worker thread to run.
* server/mpm/experimental/event/event.c
(process_socket): If the connection is in SUSPENDED state, don't force it
into linger mode yet, the callback will have to take care of that.
(push_timer2worker): New shortcut function, pushes timer event into queue
for a worker to run.
(timer_free_ring): New global data structure to recycle memory used by
timer events.
(timer_ring): New global data structure to hold active timer events.
(g_timer_ring_mtx): Thread mutex to protect timer event data structures.
(ap_mpm_register_timed_callback): New Function, registers a callback to be
invoked by the MPM at a later time.
(listener_thread): Calculate our wakeup time based on the upcoming Event
Queue, and after pollset_poll runs, push any Timers that have passed
onto worker threads to run.
(worker_thread): Call new queue pop method, and if the Timer Event is
non-null, invoke the callback. Once the callback is done, push the
structure onto the timer_free_ring, to be recycled.
(child_main): Initialize new mutex and ring structures.
* server/config.c
(ap_invoke_handler): Allow SUSPENDED aa valid return code from handlers.
* modules/http/http_core.c
(ap_process_http_async_connection): Don't close the connection when in
SUSPENDED state.
* modules/http/http_request.c
(ap_process_request_after_handler): New function, body pulled from the old,
ap_process_async_request. Split to let handlers invoke this so they
don't need to know all of the details of finishing a request.
(ap_process_async_request): If the handler returns SUSPENDED, don't do
anything but return.
* include/ap_mmn.h: Bump MMN.
* include/ap_mpm.h
(ap_mpm_register_timed_callback): New function.
* include/httpd.h:
(SUSPENDED): New return code for handlers.
(request_rec::invoke_mtx): New mutex to protect callback invokcations
from being run before the original handler finishes running.
(conn_state_e): Add a suspended state.
* include/http_request.h
(ap_process_request_after_handler): New function to make it easier for
handlers to finish the HTTP Request.
* modules/test/config.m4: Add mod_dialup to build.
* modules/test/mod_dialup.c: New rate limiting module, requires the Event MPM
to work.

This define serves no modern purpose, since every module in the wild, including
our own define it, for no purpose.
If you have functions which you do not want in the 'public' API, put them
in a private header, that is not installed, just like mod_ssl does.

ap_get_server_description().
High-level summary:
The full server version information is now included in the error log at
startup as well as server status reports, irrespective of the setting
of the ServerTokens directive.
Third-party modules must now use ap_get_server_banner() or
ap_get_server_description() in place of ap_get_server_version().

'https', mod_http returns "https" for the ap_hook_http_scheme and
DEFAULT_HTTPS_PORT for ap_hook_default_port. This fixes Redirect
responses to requests for directories without a trailing slash
when httpd runs behind a proxy or offload device that processes
SSL. It also enables support for Subversion in that
configuration. This change is completely backwards compatible
and passes the perl-framework. Minor mmn bump because I add a
field to server_rec.

Designed to minimize Apache's KeepAlive overhead.
This MPM depends on the current APR-trunk for new features added to
the apr_pollset interface. Currently the underlying operating
system must support KQueue or EPoll.
Status:
Should work as a drop in replacement for all non-ssl servers.
SSL Requests that use HTTP 1.1 Pipelining do not currently work.
Testing:
I have tested it with Linux 2.6, FreeBSD 5.2.1, and OS X 10.3.
