nginx-0.1.11-RELEASE import
*) Feature: the worker_priority directive.
*) Change: both tcp_nopush and tcp_nodelay directives affect the
transferred response.
*) Bugfix: nginx did not call initgroups().
Thanks to Andrew Sitnikov and Andrei Nigmatulin.
*) Change: now the ngx_http_autoindex_module shows the file size in the
bytes.
*) Bugfix: the ngx_http_autoindex_module returned the 500 error if the
broken symlink was in a directory.
*) Bugfix: the files bigger than 4G could not be transferred using
sendfile.
*) Bugfix: if the backend was resolved to several backends and there
was an error while the response waiting then process may got caught
in an endless loop.
*) Bugfix: the worker process may exit with the "unknown cycle" message
when the /dev/poll method was used.
*) Bugfix: "close() channel failed" errors.
*) Bugfix: the autodetection of the "nobody" and "nogroup" groups.
*) Bugfix: the send_lowat directive did not work on Linux.
*) Bugfix: the segmentation fault occurred if there was no events
section in configuration.
*) Bugfix: nginx could not be built on OpenBSD.
*) Bugfix: the double slashes in "://" in the URI were converted to
":/".
