annotate src/event/ngx_event_busy_lock.h @ 646:09a689c5e494 NGINX_1_0_13
nginx 1.0.13
*) Feature: the "return" and "error_page" directives can now be used to
return 307 redirections.
*) Bugfix: a segmentation fault might occur in a worker process if the
"resolver" directive was used and there was no "error_log" directive
specified at global level.
Thanks to Roman Arutyunyan.
*) Bugfix: memory leaks.
Thanks to Lanshun Zhou.
*) Bugfix: nginx might log incorrect error "upstream prematurely closed
connection" instead of correct "upstream sent too big header" one.
Thanks to Feibo Li.
*) Bugfix: on ZFS filesystem disk cache size might be calculated
incorrectly; the bug had appeared in 1.0.1.
*) Bugfix: the number of internal redirects to named locations was not
limited.
*) Bugfix: temporary files might be not removed if the "proxy_store"
directive was used with SSI includes.
*) Bugfix: in some cases non-cacheable variables (such as the $args
variable) returned old empty cached value.
*) Bugfix: the "proxy_redirect" directives might be inherited
incorrectly.
*) Bugfix: nginx could not be built with the ngx_http_perl_module if the
--with-openssl option was used.
*) Bugfix: nginx could not be built by the icc 12.1 compiler.
