Hello!

After more than one week's active development, the new development
version of ngx_openresty, 1.0.15.9, is now released:

Below is the change log for this release:

 *   upgraded LuaNginxModule to 0.5.0rc30.

     *   feature: new Lua API, ngx.sleep(), for doing non-blocking
         sleep in Lua. thanks jinglong for the patch.

     *   feature: ngx.log() now checks if the log level number is in
         the valid range (0 ~ 8). thanks Xiaoyu Chen (smallfish) for
         suggesting this improvement.

     *   bugfix: cosocket:receiveuntil could leak memory, especially
         for long pattern string arguments. this bug was caught by
         Test::Nginx::Socket when setting the environment
         "TEST_NGINX_CHECK_LEAK=1".

     *   bugfix: ngx.re.sub() could leak memory when the "replace"
         template argument string is not well-formed and the "o"
         regex option is also specified. this issue was caught by
         Test::Nginx::Socket when setting environment
         "TEST_NGINX_CHECK_LEAK=1".

     *   bugfix: ngx.re.gmatch leaked memory when the "o" option was
         not specified. this bug was caught by Test::Nginx::Socket
         when setting the environment "TEST_NGINX_CHECK_LEAK=1".

     *   bugfix: the Lua "_G" special table did not get cleared when
         lua_code_cache is turned off. thanks Moven for reporting
         this issue.

     *   bugfix: cosocket:connect() might hang on socket creation
         errors or segfault later due to left-over state flags.

     *   bugfix: refactored on-demand handler registration. the old
         approach rewrites to static (global) variables at
         config-time, which could have potential problems with nginx
         config reloading via the "HUP" signal.

     *   optimize: now we no longer call "ngx_http_post_request" to
         wake up the request associated with the current cosocket
         upstream from within the cosocket upstream event handlers,
         but rather call "r->write_event_handler" directly. this
         change can also make backtraces more meaningful because we
         preserve the original calling stack.

     *   docs: massive wording improvements from the Nginx Wiki site.
         thanks Dayo.

 *   upgraded RdsJsonNginxModule to 0.12rc10.

     *   bugfix: refactored on-demand handler registration. the old
         approach rewrites to static (global) variables at
         config-time, which could have potential problems with nginx
         config reloading via the "HUP" signal.

 *   bugfix: the (optional) no-pool patch might leak memory. now we
     have updated the no-pool patch to the latest version that is a
     thorough rewrite.

 *   bugfix: applied poll_del_event_at_exit patch that fixed a
     segmentation fault in the nginx core when the poll event type is
     used:
     <http://mailman.nginx.org/pipermail/nginx-devel/2012-June/002328.html>

 *   bugfix: applied the resolver_debug_log patch that fixed reads of
     uninitialized memory in the nginx core:
     <http://mailman.nginx.org/pipermail/nginx-devel/2012-June/002281.html>

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

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

Have fun!
