annotate src/core/ngx_crc32.h @ 358:9121a0a91f47 NGINX_0_6_23
nginx 0.6.23
*) Change: the "off" parameter in the "ssl_session_cache" directive;
now this is default parameter.
*) Change: the "open_file_cache_retest" directive was renamed to the
"open_file_cache_valid".
*) Feature: the "open_file_cache_min_uses" directive.
*) Feature: the ngx_http_gzip_static_module.
*) Feature: the "gzip_disable" directive.
*) Feature: the "memcached_pass" directive may be used inside the "if"
block.
*) Bugfix: a segmentation fault occurred in worker process, if the
"memcached_pass" and "if" directives were used in the same location.
*) Bugfix: if a "satisfy_any on" directive was used and not all access
and auth modules directives were set, then other given access and
auth directives were not tested;
*) Bugfix: regex parameters in a "valid_referers" directive were not
inherited from previous level.
*) Bugfix: a "post_action" directive did run if a request was completed
with 499 status code.
*) Bugfix: optimization of 16K buffer usage in a SSL connection.
Thanks to Ben Maurer.
*) Bugfix: the STARTTLS in SMTP mode did not work.
Thanks to Oleg Motienko.
*) Bugfix: in HTTPS mode requests might fail with the "bad write retry"
error; bug appeared in 0.5.13.
