annotate src/http/ngx_http_busy_lock.h @ 50:72eb30262aac NGINX_0_1_25

nginx 0.1.25 *) Bugfix: nginx did run on Linux parisc. *) Feature: nginx now does not start under FreeBSD if the sysctl kern.ipc.somaxconn value is too big. *) Bugfix: if a request was internally redirected by the ngx_http_index_module module to the ngx_http_proxy_module or ngx_http_fastcgi_module modules, then the index file was not closed after request completion. *) Feature: the "proxy_pass" can be used in location with regular expression. *) Feature: the ngx_http_rewrite_filter_module module supports the condition like "if ($HTTP_USER_AGENT ~ MSIE)". *) Bugfix: nginx started too slow if the large number of addresses and text values were used in the "geo" directive. *) Change: a variable name must be declared as "$name" in the "geo" directive. The previous variant without "$" is still supported, but will be removed soon. *) Feature: the "%{VARIABLE}v" logging parameter. *) Feature: the "set $name value" directive. *) Bugfix: gcc 4.0 compatibility. *) Feature: the --with-openssl-opt=OPTIONS autoconfiguration directive.
