Version bump.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4912 73f98a42-aea0-e011-b76d-00259023448c
Fixed setting of CPU affinity on respawn of dead worker processes.

Worker processes are now made aware of their sequential number needed
to select CPU affinity mask.  This replaces a workaround from r4865.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4913 73f98a42-aea0-e011-b76d-00259023448c
Variables $request_time and $msec.

Log module counterparts are preserved for efficiency.

Upstream: honor the "down" flag for a single server.

If an upstream block was defined with the only server marked as
"down", e.g.

    upstream u {
        server 127.0.0.1:8080 down;
    }

an attempt was made to contact the server despite the "down" flag.
It is believed that immediate 502 response is better in such a
case, and it's also consistent with what is currently done in case
of multiple servers all marked as "down".

Upstream: better detection of connect() failures with kqueue.

Pending EOF might be reported on both read and write events, whichever
comes first, so check both of them.

Patch by Yichun Zhang (agentzh), slightly modified.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4916 73f98a42-aea0-e011-b76d-00259023448c
Trailing whitespace fix.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4917 73f98a42-aea0-e011-b76d-00259023448c
Fixed failure to start cache manager and cache loader processes
if there were more than 512 listening sockets in configuration.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4918 73f98a42-aea0-e011-b76d-00259023448c
Dav: fixed segfault on PUT if body was already read (ticket #238).

If request body reading happens with different options it's possible
that there will be no r->request_body->temp_file available (or even
no r->request_body available if body was discarded).  Return internal
server error in this case instead of committing suicide by dereferencing
a null pointer.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4919 73f98a42-aea0-e011-b76d-00259023448c
Core: added debug logging of writev() in ngx_write_chain_to_file().


git-svn-id: svn://svn.nginx.org/nginx/trunk@4920 73f98a42-aea0-e011-b76d-00259023448c
Request body: fixed "501 Not Implemented" error handling.

It is not about "Method" but a generic message, and is expected to be used
e.g. if specified Transfer-Encoding is not supported.  Fixed message to
match RFC 2616.

Additionally, disable keepalive on such errors as we won't be able to read
request body correctly if we don't understand Transfer-Encoding used.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4921 73f98a42-aea0-e011-b76d-00259023448c
Request body: $request_body variable generalization.

The $request_body variable was assuming there can't be more than two
buffers.  While this is currently true due to request body reading
implementation details, this is not a good thing to depend on and may
change in the future.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4922 73f98a42-aea0-e011-b76d-00259023448c
Request body: code duplication reduced, no functional changes.

The r->request_body_in_file_only with empty body case is now handled in
ngx_http_write_request_body().


git-svn-id: svn://svn.nginx.org/nginx/trunk@4923 73f98a42-aea0-e011-b76d-00259023448c
Request body: fixed socket leak on errors.

The r->main->count reference counter was always incremented in
ngx_http_read_client_request_body(), while it is only needs to be
incremented on positive returns.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4924 73f98a42-aea0-e011-b76d-00259023448c
Request body: properly handle events while discarding body.

An attempt to call ngx_handle_read_event() before actually reading
data from a socket might result in read event being disabled, which is
wrong.  Catched by body.t test on Solaris.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4925 73f98a42-aea0-e011-b76d-00259023448c
Request body: chunked parsing moved to ngx_http_parse.c from proxy.

No functional changes.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4926 73f98a42-aea0-e011-b76d-00259023448c
Request body: adjust b->pos when chunked parsing done.

This is a nop for the current code, though will allow to correctly parse
pipelined requests.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4927 73f98a42-aea0-e011-b76d-00259023448c
Request body: always use calculated size of a request body in proxy.

This allows to handle requests with chunked body, and also simplifies
handling of various request body modifications.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4928 73f98a42-aea0-e011-b76d-00259023448c
Request body: $content_length variable to honor real body size.

This allows to handle requests with chunked body by fastcgi and uwsgi
modules, and also simplifies handling of various request body modifications.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4929 73f98a42-aea0-e011-b76d-00259023448c
Request body: recalculate size of a request body in scgi module.

This allows to handle requests with chunked body by scgi module, and
also simplifies handling of various request body modifications.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4930 73f98a42-aea0-e011-b76d-00259023448c
Request body: chunked transfer encoding support.


git-svn-id: svn://svn.nginx.org/nginx/trunk@4931 73f98a42-aea0-e011-b76d-00259023448c
