annotate src/core/ngx_slab.h @ 430:dac47e9ef0d5 NGINX_0_7_27

nginx 0.7.27 *) Feature: the "try_files" directive. *) Feature: variables support in the "fastcgi_pass" directive. *) Feature: now the $geo variable may get an address from a variable. Thanks to Andrei Nigmatulin. *) Feature: now a location's modifier may be used without space before name. *) Feature: the $upstream_response_length variable. *) Bugfix: now a "add_header" directive does not add an empty value. *) Bugfix: if zero length static file was requested, then nginx just closed connection; the bug had appeared in 0.7.25. *) Bugfix: a MOVE method could not move file in non-existent directory. *) Bugfix: a segmentation fault occurred in worker process, if no one named location was defined in server, but some one was used in an error_page directive. Thanks to Sergey Bochenkov.
