84b0ad63fb Win32: MSVC 2015 compatibility.
Resolved warnings about declarations that hide previous local declarations.
Warnings about WSASocketA() being deprecated resolved by explicit use of
WSASocketW() instead of WSASocket().  When compiling without IPv6 support,
WinSock deprecated warnings are disabled to allow use of gethostbyname().

05982ffdf5 Fixed wrong URI after try_files in nested location (ticket #97).
The following configuration with alias, nested location and try_files
resulted in wrong file being used.  Request "/foo/test.gif" tried to
use "/tmp//foo/test.gif" instead of "/tmp/test.gif":

    location /foo/ {
        alias /tmp/;
        location ~ gif {
            try_files $uri =405;
        }
    }

Additionally, rev. c985d90a8d1f introduced a regression if
the "/tmp//foo/test.gif" file was found (ticket #768).  Resulting URI
was set to "gif?/foo/test.gif", as the code used clcf->name of current
location ("location ~ gif") instead of parent one ("location /foo/").

Fix is to use r->uri instead of clcf->name in all cases in the
ngx_http_core_try_files_phase() function.  It is expected to be
already matched and identical to the clcf->name of the right
location.

4fec72dc8c Fixed segfault with try_files introduced by c985d90a8d1f.
If alias was used in a location given by a regular expression,
nginx used to do wrong thing in try_files if a location name (i.e.,
regular expression) was an exact prefix of URI.  The following
configuration triggered a segmentation fault on a request to "/mail":

    location ~ /mail {
        alias /path/to/directory;
        try_files $uri =404;
    }

50ff8b3c3a Core: idle connections now closed only once on exiting.
Iterating through all connections takes a lot of CPU time, especially
with large number of worker connections configured.  As a result
nginx processes used to consume CPU time during graceful shutdown.
To mitigate this we now only do a full scan for idle connections when
shutdown signal is received.

Transitions of connections to idle ones are now expected to be
avoided if the ngx_exiting flag is set.  The upstream keepalive module
was modified to follow this.

97741382b6 Workaround for "configuration file test failed" under OpenVZ.
If nginx was used under OpenVZ and a container with nginx was suspended
and resumed, configuration tests started to fail because of EADDRINUSE
returned from listen() instead of bind():

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] listen() to 0.0.0.0:80, backlog 511 failed (98: Address already in use)
nginx: configuration file /etc/nginx/nginx.conf test failed

With this change EADDRINUSE errors returned by listen() are handled
similarly to errors returned by bind(), and configuration tests work
fine in the same environment:

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

3ac176fb86 OCSP stapling: fixed segfault without nextUpdate.
OCSP responses may contain no nextUpdate.  As per RFC 6960, this means
that nextUpdate checks should be bypassed.  Handle this gracefully by
using NGX_MAX_TIME_T_VALUE as "valid" in such a case.

The problem was introduced by 6893a1007a7c (1.9.2).

With this change it's no longer needed to pass -D_GNU_SOURCE manually,
and -D_FILE_OFFSET_BITS=64 is set to use 64-bit off_t.

Note that nginx currently fails to work properly with master process
enabled on GNU Hurd, as fcntl(F_SETOWN) returns EOPNOTSUPP for sockets
as of GNU Hurd 0.6.  Additionally, our strerror() preloading doesn't
work well with GNU Hurd, as it uses large numbers for most errors.

f7f1607bf2 The "reuseport" option of the "listen" directive.
When configured, an individual listen socket on a given address is
created for each worker process.  This allows to reduce in-kernel lock
contention on configurations with high accept rates, resulting in better
performance.  As of now it works on Linux and DragonFly BSD.

Note that on Linux incoming connection requests are currently tied up
to a specific listen socket, and if some sockets are closed, connection
requests will be reset, see https://lwn.net/Articles/542629/.  With
nginx, this may happen if the number of worker processes is reduced.
There is no such problem on DragonFly BSD.

Based on previous work by Sepherosa Ziehau and Yingqi Lu.

d5c34785bc Simplified ngx_http_init_listening().
There is no need to set "i" to 0, as it's expected to be 0 assuming
the bindings are properly sorted, and we already rely on this when
explicitly set hport->naddrs to 1.  Remaining conditional code is
replaced with identical "hport->naddrs = i + 1".

Identical modifications are done in the mail and stream modules,
in the ngx_mail_optimize_servers() and ngx_stream_optimize_servers()
functions, respectively.

No functional changes.

2ec8cfcd7d Win32: shared memory base addresses and remapping.
Two mechanisms are implemented to make it possible to store pointers
in shared memory on Windows, in particular on Windows Vista and later
versions with ASLR:

- The ngx_shm_remap() function added to allow remapping of a shared memory
  zone to the address originally used for it in the master process.  While
  important, it doesn't solve the problem by itself as in many cases it's
  not possible to use the address because of conflicts with other
  allocations.

- We now create mappings at the same address in all processes by starting
  mappings at predefined addresses normally unused by newborn processes.

These two mechanisms combined allow to use shared memory on Windows
almost without problems, including reloads.

38a97edf3a Core: limited levels of subdirectory hierarchy used for temp files.
Similar to ngx_http_file_cache_set_slot(), the last component of file->name
with a fixed length of 10 bytes, as generated in ngx_create_temp_path(), is
used as a source for the names of intermediate subdirectories with each one
taking its own part.  Ensure that the sum of specified levels with slashes
fits into the length (ticket #731).

0e853129ac SPDY: always push pending data.
This helps to avoid suboptimal behavior when a client waits for a control
frame or more data to increase window size, but the frames have been delayed
in the socket buffer.

The delays can be caused by bad interaction between Nagle's algorithm on
nginx side and delayed ACK on the client side or by TCP_CORK/TCP_NOPUSH
if SPDY was working without SSL and sendfile() was used.

The pushing code is now very similar to ngx_http_set_keepalive().

5e96e84ffb Proxy: fixed proxy_request_buffering and chunked with preread body.
If any preread body bytes were sent in the first chain, chunk size was
incorrectly added before the whole chain, including header, resulting in
an invalid request sent to upstream.  Fixed to properly add chunk size
after the header.

2743bb68ee Request body: unbuffered reading.
The r->request_body_no_buffering flag was introduced.  It instructs
client request body reading code to avoid reading the whole body, and
to call post_handler early instead.  The caller should use the
ngx_http_read_unbuffered_request_body() function to read remaining
parts of the body.

Upstream module is now able to use this mode, if configured with
the proxy_request_buffering directive.

58eb93f791 Proxy: fixed proxy_set_body with proxy_cache.
If the last header evaluation resulted in an empty header, the e.skip flag
was set and was not reset when we've switched to evaluation of body_values.
This incorrectly resulted in body values being skipped instead of producing
some correct body as set by proxy_set_body.  Fix is to properly reset
the e.skip flag.

As the problem only appeared if the last potentially non-empty header
happened to be empty, it only manifested itself if proxy_set_body was used
with proxy_cache.

47c44355b5 SSL: use of SSL_MODE_NO_AUTO_CHAIN.
The SSL_MODE_NO_AUTO_CHAIN mode prevents OpenSSL from automatically
building a certificate chain on the fly if there is no certificate chain
explicitly provided.  Before this change, certificates provided via the
ssl_client_certificate and ssl_trusted_certificate directives were
used by OpenSSL to automatically build certificate chains, resulting
in unexpected (and in some cases unneeded) chains being sent to clients.

a20c6d202e SSL: avoid SSL_CTX_set_tmp_rsa_callback() call with LibreSSL.
LibreSSL removed support for export ciphers and a call to
SSL_CTX_set_tmp_rsa_callback() results in an error left in the error
queue.  This caused alerts "ignoring stale global SSL error (...called
a function you should not call) while SSL handshaking" on a first connection
in each worker process.

with LibreSSL if enabled in nginx config.

cc569b9252 Core: added cyclic memory buffer support for error_log.
Example of usage:

  error_log memory:16m debug;

This allows to configure debug logging with minimum impact on performance.
It's especially useful when rare crashes are experienced under high load.

The log can be extracted from a coredump using the following gdb script:

  set $log = ngx_cycle->log

  while $log->writer != ngx_log_memory_writer
      set $log = $log->next
  end

  set $buf = (ngx_log_memory_buf_t *) $log->wdata
  dump binary memory debug_log.txt $buf->start $buf->end
