annotate src/core/ngx_slab.h @ 684:660139fd80ca NGINX_1_3_5
nginx 1.3.5
*) Change: the ngx_http_mp4_module module no longer skips tracks in
formats other than H.264 and AAC.
*) Bugfix: a segmentation fault might occur in a worker process if the
"map" directive was used with variables as values.
*) Bugfix: a segmentation fault might occur in a worker process if the
"geo" directive was used with the "ranges" parameter but without the
"default" parameter; the bug had appeared in 0.8.43.
Thanks to Zhen Chen and Weibin Yao.
*) Bugfix: in the -p command-line parameter handling.
*) Bugfix: in the mail proxy server.
*) Bugfix: of minor potential bugs.
Thanks to Coverity.
*) Bugfix: nginx/Windows could not be built with Visual Studio 2005
Express.
Thanks to HAYASHI Kentaro.
