If a subreq added a filter (say INCLUDES) and the subreq was promoted via · 07060a28

Justin Erenkrantz authored Apr 28, 2002

fast_redirect, the filter would still point at the subreq - rather than
the original r.  So, we must update any filters pointing at rr to be r.

This would cause lots of problems with mod_include with mod_dir requests
such as seen in PR 7966.  mod_include would be unsetting the headers_out
of rr instead of r.  But, we disassociate rr->headers_out and r->headers_out.
Therefore, the C-L header in r->headers_out would remain - even though it
bears no relation to what we will be outputting - causing problems.

This also now permits chunked-encoding of mod_dir/mod_include requests
which could never happen before and fixes the content-length problem
seen in PR 7966.

As hinted at in PR 7966, there is a race condition - if for some reason
the server stalls reading an included file (or even better, placing a
sleep in the cgi-bin script!), the invalid C-L may get propogated to the
client.

(Note that internal_internal_redirect has this same code fragment.)

Add a "queue_info" structure to the worker MPM. This is used to prevent · 74e62132

Aaron Bannert authored Apr 28, 2002

the listener thread from accept()ing more connections than there are
available workers. This prevents long-running requests from starving
connections that have been accepted but not yet processed.

The queue_info is a simple counter, mutex, and condition variable. Only
the listener thread blocks on the condition, and only when there are no
idle workers. In the fast path there is a mutex lock, integer decrement,
and and unlock (among a few conditionals). The worker threads each notify
the queue_info when they are about to block on the normal worker_queue
waiting for some connection to process, which wakes up any sleeping
listener thread to go perform another accept() in parallel.

elements in the queue represent accept()ed connections, we want them

improve cache efficiency.)

Remember to perform a make clean in the worker directory after this patch,
since this patch changes the size of the fd_queue_t object (which is
allocated in worker.c).
