1.2.6.3:

Special thanks go to all our contributors and users for helping make this
happen!

Below is the complete change log for this release, as compared to the last
(development) release, 1.2.6.1:

* upgraded LuaNginxModule to 0.7.14.

* feature: implemented named subpattern support in
ngx.re.match, ngx.re.gmatch, ngx.re.sub, and ngx.re.gsub;
also added new regex option "D" to allow duplicate named
subpattern names. thanks Ray Bejjani for the patch.

* feature: implemented the "J" regex option for the PCRE
Javascript compatible mode in the ngx.re API. thanks lhmwzy
for requesting this.

* feature: setting ngx.header.HEADER after sending out the
response headers now only produced an error message in the
Nginx error logs and does not throw out a Lua exception.
this should be handy for Lua development. thanks Matthieu
Tourne for requesting this.

* feature: automatic Lua 5.1 interpreter detection on OpenBSD
5.2. thanks Ilya Shipitsin for the patch.

* refactor: when the Nginx core fails to send the "100
Continue" response in case of the "Expect: 100-continue"
request header (or just running out of memory),
ngx.req.read_body() will no longer throw out a "failed to
read request body" Lua error but will just terminate the
current request and returns the 500 error page immediately,
just as what the Nginx core currently does in this case.

* bugfix: because of the recent API behaviour changes in Nginx
1.2.6+ and 1.3.9+, the "http request count is zero" alert
might happen when ngx.req.read_body() was called to read the
request body and Nginx failed to send out the "100 Continue"
response (like client connection early abortion and etc).
thanks stonehuzhan for reporting this issue.

* bugfix: setting the "eof" argument (i.e., "ngx.arg[2]") in
body_filter_by_lua* for a subrequest could truncate the main
request's response data stream.

* bugfix: in body_filter_by_lua*, the "eof" argument (i.e.,
"ngx.arg[2]") was never set in Nginx subrequests.

* bugfix: for nginx 1.3.9+ compatibility, we return an error
while using ngx.req.socket() to read the chunked request
body (for now), because chunked support in the downstream
cosocket API is still a TODO.

* bugfix: for nginx 1.3.9+ compatibility, rewrite_by_lua* or
access_by_lua* handlers might hang if the request body was
read there, because the Nginx core now overwrites
"r->write_event_handler" to "ngx_http_request_empty_handler"
in its "ngx_http_read_client_request_body" API.

* bugfix: for nginx 1.3.9+ compatibility, we now throw an
error in ngx.req.init_body(), ngx.req.set_body_data(), and
ngx.req.set_body_file() when calling them without calling
ngx.req.read_body() or after calling ngx.req.discard_body().

* bugfix: a compilation error would happen when building with
an Nginx core patched by the SPDY patch 58_1.3.11 because
the patch had removed a request field from the Nginx core.
thanks Chris Lea for reporting this.

* bugfix: we did not get the request reference counter (i.e.,
"r->main->count") right when lua_need_request_body was
turned on and Nginx versions older than 1.2.6 or 1.2.9 were
used.

* optimize: we no longer traverse the captured body chain
every time we append a new link to it in ngx.location.capture
and ngx.location.capture_multi.

* docs: documented the ngx.quote_sql_str API.

* upgraded SrcacheNginxModule to 0.18.

* bugfix: we might serve a truncated srcache_fetch
subrequest's response body as the cached response.

* upgraded EchoNginxModule to 0.42.

* feature: the echo_after_body directive is now enabled in
Nginx subrequests (again).

* bugfix: we did not set the "last_in_chain" buffer flag when
echo_after_body was used in subrequests.

* upgraded FormInputNginxModule to 0.07.

* bugfix: Nginx might hang when it failed to send the "100
Continue" response for Nginx versions older than 1.2.6 (and
those older than 1.3.9 in the 1.3.x series).

* upgraded NginxDevelKit ot 0.2.18.

* bugfix: various fixes for C89 compliance. also stripped some
line-trailing spaces.

* bugfix: guard macros were missing in the "ndk_set_var.h"
header file.

* bugfix: the "ndk_string" submodule failed to compile with
gcc 4.6. thanks Jon Kolb for the patch.

* bugfix: the "ndk_set_var" example did not use the new way in
its "config" file. thanks Amos Wenger for the patch.

* docs: fixes in README to reflect recent changes. thanks Amos
Wenger for the patch.

* applied Ruslan Ermilov's resolver_wev_handler_segfault_with_poll
patch to the Nginx core bundled. see the related nginx-devel
thread for details.

* excluded the allow_request_body_updating patch from the Nginx
core bundled.

OpenResty (aka. ngx_openresty) is a full-fledged web application server by
bundling the standard Nginx core, lots of 3rd-party Nginx modules and Lua
libraries, as well as most of their external dependencies. See OpenResty's
homepage for details:

http://openresty.org/

We have been running extensive testing on our Amazon EC2 test cluster and
ensure that all the components (including the Nginx core) play well
together. The latest test report can always be found here:

Enjoy!
