6d52912a2a Cache: proper wakeup of subrequests.
In case of a cache lock timeout and in the aio handler we now call
r->write_event_handler() instead of a connection write handler,
to make sure to run appropriate subrequest.  Previous code failed to run
inactive subrequests and hence resulted in suboptimal behaviour, see
report by Yichun Zhang:

http://mailman.nginx.org/pipermail/nginx-devel/2013-October/004435.html

(Infinite hang claimed in the report seems impossible without 3rd party
modules, as subrequests will be eventually woken up by the postpone filter.)

10345663c8 Upstream: improved subrequest logging.
To ensure proper logging make sure to set current_request in all event
handlers, including resolve, ssl handshake, cache lock wait timer and
aio read handlers.  A macro ngx_http_set_log_request() introduced to
simplify this.

778cc4b42e Access log: restricted "log_format" to "http" level.
Specifying the "log_format" directive on levels other than "http"
is deprecated since 73d37e1ccb91 (1.1.11).

7fa89c744a Fixed post_action to not trigger "header already sent" alert.
The alert was introduced in 03ff14058272 (1.5.4), and was triggered on each
post_action invocation.

There is no real need to call header filters in case of post_action,
so return NGX_OK from ngx_http_send_header() if r->post_action is set.

decaffa805 SPDY: push pending data while closing a stream as with keepalive.
This helps to avoid delays in sending the last chunk of data because
of bad interaction between Nagle's algorithm on nginx side and
delayed ACK on the client side.

Delays could also be caused by TCP_CORK/TCP_NOPUSH if SPDY was
working without SSL and sendfile() was used.

ef563debf1 Resolver: fixed debug event logging.
In 954867a2f0a6, we switched to using resolver node as the timer event data.
This broke debug event logging.

Replaced now unused ngx_resolver_ctx_t.ident with ngx_resolver_node_t.ident
so that ngx_event_ident() extracts something sensible when accessing
ngx_resolver_node_t as ngx_connection_t.

d4b7b74686 Resolver: fixed use-after-free memory access.
In 954867a2f0a6, we switched to using resolver node as the

memory until the corresponding timer is deleted.

1276d8483e Fixed type of sendfile() return value on Linux.
There was no real problem since the amount of bytes can be sent is limited by
NGX_SENDFILE_MAXSIZE to less than 2G.  But that can be changed in the future

f00918eab3 Refactored ngx_solaris_sendfilev_chain().
Though ngx_solaris_sendfilev_chain() shouldn't suffer from the problem mentioned
in d1bde5c3c5d2 since currently IOV_MAX on Solaris is 16, but this follows the
change from 3d5717550371 in order to make the code look similar to other systems
and potentially eliminates the problem in the future.

b29d599c0b Introduced the ngx_output_chain_to_iovec() function.
It deduplicates code of the send chain functions and uses only preallocated
memory, which completely solves the problem mentioned in d1bde5c3c5d2.

8898c97dbd Upstream: different header lists for cached and uncached requests.
The upstream modules remove and alter a number of client headers
before sending the request to upstream.  This set of headers is
smaller or even empty when cache is disabled.

It's still possible that a request in a cache-enabled location is
uncached, for example, if cache entry counter is below min_uses.
In this case it's better to alter a smaller set of headers and
pass more client headers to backend unchanged.  One of the benefits
is enabling server-side byte ranges in such requests.

20d41493d4 SPDY: fixed check for too long header name or value.
For further progress a new buffer must be at least two bytes larger than
the remaining unparsed data.  One more byte is needed for null-termination
and another one for further progress.  Otherwise inflate() fails with
Z_BUF_ERROR.

2d16e3c3a1 Contrib: add more directives to vim syntax.
uwsgi is not a third-party module anymore. 'split_clients' is a new
block directive type. The directives were automatically extracted from
the ngx_command_t arrays, sorted in the C locale and inserted.

Trailing spaces got removed at some places.

33f5555940 SSL: simplified ssl_password_file error handling.
Instead of collecting a number of the possible SSL_CTX_use_PrivateKey_file()
error codes that becomes more and more difficult with the rising variety of
OpenSSL versions and its derivatives, just continue with the next password.

Multiple passwords in a single ssl_password_file feature was broken after
recent OpenSSL changes (commit 4aac102f75b517bdb56b1bcfd0a856052d559f6e).

Affected OpenSSL releases: 0.9.8zc, 1.0.0o, 1.0.1j and 1.0.2-beta3.

54606d4625 SPDY: stop emitting multiple empty header values.
Previously, nginx would emit empty values in a header with multiple,
NULL-separated values.

This is forbidden by the SPDY specification, which requires headers to
have either a single (possibly empty) value or multiple, NULL-separated
non-empty values.
