nginx/src/event/ngx_event_openssl.c
Igor Sysoev c2068d08f0 nginx-0.3.3-RELEASE import 
*) Change: the "bl" and "af" parameters of the "listen" directive was
       renamed to the "backlog" and "accept_filter".

    *) Feature: the "rcvbuf" and "sndbuf" parameters of the "listen"
       directive.

    *) Change: the "$msec" log parameter does not require now the
       additional the gettimeofday() system call.

    *) Feature: the -t switch now tests the "listen" directives.

    *) Bugfix: if the invalid address was specified in the "listen"
       directive, then after the -HUP signal nginx left an open socket in
       the CLOSED state.

    *) Bugfix: the mime type may be incorrectly set to default value for
       index file with variable in the name; the bug had appeared in 0.3.0.

    *) Feature: the "timer_resolution" directive.

    *) Feature: the millisecond "$upstream_response_time" log parameter.

    *) Bugfix: a temporary file with client request body now is removed
       just after the response header was transferred to a client.

    *) Bugfix: OpenSSL 0.9.6 compatibility.

    *) Bugfix: the SSL certificate and key file paths could not be relative.

    *) Bugfix: the "ssl_prefer_server_ciphers" directive did not work in
       the ngx_imap_ssl_module.

    *) Bugfix: the "ssl_protocols" directive allowed to specify the single
       protocol only.
