annotate src/core/ngx_slab.h @ 558:2da4537168f8 NGINX_0_8_31

nginx 0.8.31 *) Feature: now the "error_page" directive may redirect the 301 and 302 responses. *) Feature: the $geoip_city_continent_code, $geoip_latitude, and $geoip_longitude variables. Thanks to Arvind Sundararajan. *) Feature: now the ngx_http_image_filter_module deletes always EXIF and other application specific data if the data consume more than 5% of a JPEG file. *) Bugfix: nginx closed a connection if a cached response had an empty body. Thanks to Piotr Sikora. *) Bugfix: nginx might not be built by gcc 4.x if the -O2 or higher optimization option was used. Thanks to Maxim Dounin and Denis F. Latypoff. *) Bugfix: regular expressions in location were always tested in case-sensitive mode; the bug had appeared in 0.8.25. *) Bugfix: nginx cached a 304 response if there was the "If-None-Match" header line in a proxied request. Thanks to Tim Dettrick and David Kostal. *) Bugfix: nginx/Windows tried to delete a temporary file twice if the file should replace an already existent file.
