nginx.git/src/core/ngx_log.c, branch release-1.29.2

Core: "-e" command line option.

When installing or running from a non-root user it is sometimes required to
override default, compiled in error log path. There was no way to do this
without rebuilding the binary (ticket #147).

This patch introduced "-e" command line option which allows one to override
compiled in error log path.

Removed the prototype mysql module.

Core: properly initialized written bytes counter in memory log.

2015-05-19T16:27:07+00:00

Stream: port from NGINX+.

Core: added cyclic memory buffer support for error_log.

2015-03-19T16:29:43+00:00

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

Log: use ngx_cpymem() in a couple of places, no functional changes.

2015-03-04T16:20:30+00:00

Core: added disk_full_time checks to error log.

2015-01-13T16:51:37+00:00

Core: fixed default log initialization.

2014-07-24T12:25:07+00:00

The ngx_log_insert() function may invalidate pointer passed to it,
so make sure to don't use it after the ngx_log_insert() call.

Added syslog support for error_log and access_log directives.
