Use of accept mutex on win32 may result in a deadlock if there are multiple
worker_processes configured and the mutex is grabbed by a process which
can't accept connections.
The parameter is mostly identical to http_404, and is expected to
be used in similar situations. The 403 code might be returned by
a backend instead of 404 on initial sync of new directories with rsync.

It is now a syntax error if tokens passed to a custom configuration
handler are terminated by "{".
The following incorrect configuration is now properly rejected:
map $v $v2 {
a b {
c d {
e f {
}
An invalid memcached reply that started with '\n' could cause
segmentation fault.
An invalid memcached reply "VALUE / 0 2\r?ok\r\nEND\r\n" was
considered as a valid response.
In addition, if memcached reports that the key was not found,
set u->headers_in.content_length_n to 0. This ensures that
ngx_http_memcached_filter() will not be called while previous
code relied on always intercepting 404. Initialization of
ctx->rest was moved to where it belongs.
Due to peer->checked always set since rev. c90801720a0c (1.3.0)
by round-robin and least_conn balancers (ip_hash not affected),
the code in ngx_http_upstream_free_round_robin_peer() function
incorrectly reset peer->fails too often.

Due to a bad argument list, nginx worker would crash (SIGSEGV) while
trying to log the fact that it received OCSP response with "revoked"
or "unknown" certificate status.
While there, fix similar (but non-crashing) error a few lines above.

There are two significant changes in this patch:
1) The <= 0 comparison is done with a signed type. This fixes the case
of ngx_time() being larger than r->lingering_time.
2) Calculation of r->lingering_time - ngx_time() is now always done
in the ngx_msec_t type. This ensures the calculation is correct
even if time_t is unsigned and differs in size from ngx_msec_t.

Previously, input pattern was kept only for regular expressions
with named captures, which resulted in error log entries without
input pattern for PCRE errors that occured while processing
regular expressions without them.

The $proxy_internal_body_length value might change during request lifetime,
notably if proxy_set_body used, and use of a cached value might result in
incorrect upstream requests.

As of now, it allows to better control bandwidth limiting from additional
modules. It is also expected to be used to add variables support to
the limit_rate_after directive.
If nginx was compiled without --with-http_ssl_module, but with some
other module which uses OpenSSL (e.g. --with-mail_ssl_module), insufficient
preprocessor check resulted in build failure. The problem was introduced
by e0a3714a36f8 (1.3.14).

This is to avoid setting the TCP_NODELAY flag on SPDY socket in
ngx_http_upstream_send_response(). The latter works per request,
but in SPDY case it might affect other streams in connection.
As of 1.3.9, chunked request body may be available with
r->headers_in.content_length_n <= 0. Additionally, request body
may be in multiple buffers even if r->request_body_in_single_buf
was requested.
Dependancy tracking introduced in r5169 were not handled absolute path
names properly. Absolute names might appear in CORE_DEPS if --with-openssl
or --with-pcre configure arguments are used to build OpenSSL/PCRE
libraries.
Additionally, revert part of r5169 to set NGX_INCS from Makefile
variables. Makefile variables have $ngx_include_opt in them, which
might result in wrong include paths being used. As a side effect,
this also restores build with --with-http_perl_module and --without-http
at the same time.
