nginx-1.7.7-RELEASE

2014-10-28T15:04:46+00:00

Updated OpenSSL used for win32 builds.

2014-10-28T14:35:00+00:00

Win32: made build-able with MinGW-w64 gcc.

Upstream: limited next_upstream time and tries when resolving DNS.

2014-10-27T11:52:03+00:00

When got multiple upstream IP addresses using DNS resolving, the number of
upstreams tries and the maxinum time spent for these tries were not affected.
This patch fixed it.

Write filter: stored delay in a variable, no functional changes.

2014-10-28T09:29:59+00:00

The code is now similar to ngx_event_pipe_read_upstream().

Upstream: proxy_limit_rate and friends.

2014-10-28T09:29:59+00:00

The directives limit the upstream read rate.  For example,
"proxy_limit_rate 42" limits proxy upstream read rate to
42 bytes per second.

Core: added limit to recv_chain().

2014-10-28T09:29:58+00:00

Cache: normalization of some Vary headers.

2014-10-27T18:14:12+00:00

Spaces in Accept-Charset, Accept-Encoding, and Accept-Language headers
are now ignored.  As per syntax of these headers spaces can only appear
in places where they are optional.

Cache: multiple variants of a resource now can be stored.

2014-10-27T18:14:10+00:00

If a variant stored can't be used to respond to a request, the variant
hash is used as a secondary key.

Additionally, if we previously switched to a secondary key, while storing
a response to cache we check if the variant hash still apply.  If not, we
switch back to the original key, to handle cases when Vary changes.

Cache: c->reading flag introduced.

2014-10-27T18:14:07+00:00

It replaces c->buf in checks in ngx_http_file_cache_open(), making it possible
to reopen the file without clearing c->buf.  No functional changes.
