annotate src/core/ngx_crc.h @ 168:3314be145cb9 NGINX_0_3_31
nginx 0.3.31
*) Change: now nginx passes the malformed proxied backend responses.
*) Feature: the "listen" directives support the address in the "*:port"
form.
*) Feature: the EVFILER_TIMER support in MacOSX 10.4.
*) Workaround: for MacOSX 64-bit kernel kqueue millisecond timeout
bug.
Thanks to Andrei Nigmatulin.
*) Bugfix: if there were several "listen" directives listening one
various addresses inside one server, then server names like
"*.domain.tld" worked for first address only; bug appeared in 0.3.18.
*) Bugfix: if the HTTPS protocol was used in the "proxy_pass" directive
and the request body was in temporarily file then the request was
not transferred.
*) Bugfix: perl 5.8.8 compatibility.
