Event pipe: fixed handling of buf_to_file data.

2012-10-30T11:14:24+00:00

Input filter might free a buffer if there is no data in it, and in case
of first buffer (used for cache header and request header, aka p->buf_to_file)
this resulted in cache corruption.  Buffer memory was reused to read upstream
response before headers were written to disk.

Fix is to avoid moving pointers in ngx_event_pipe_add_free_buf() to a buffer
start if we were asked to free a buffer used by p->buf_to_file.

This fixes occasional cache file corruption, usually resulted
in "cache file ... has md5 collision" alerts.

Reported by Anatoli Marinov.

Style, parentheses instead of braces in misc/GNUMakefile.

Variables $connection and $connection_requests.

2012-10-29T17:17:59+00:00

Log module counterparts are removed as they aren't used often and
there is no need to preserve them for efficiency.

Resolver: added missing memory allocation error handling.

2012-10-24T14:07:08+00:00

ngx_http_keepalive_handler() is now trying to not keep c->buffer's memory for

2012-10-23T14:36:18+00:00

idle connections.

This behaviour is consistent with the ngx_http_set_keepalive() function and it
should decrease memory usage in some cases (especially if epoll/rtsig is used).

Core: the "auto" parameter of the "worker_processes" directive.

2012-10-23T09:08:41+00:00

The parameter will set the number of worker processes to the
autodetected number of available CPU cores.

Removed conditional compilation from waitpid() error test.

2012-10-18T14:48:33+00:00

There are reports that call to a signal handler for an exited process
despite waitpid() already called for the process may happen on Linux
as well.

Gunzip: fixed r->gzip_ok check.

OCSP stapling: properly check if there is ssl.ctx.

2012-10-05T11:09:14+00:00

This fixes segfault if stapling was enabled in a server without a certificate
configured (and hence no ssl.ctx).
