  • bugfix: ngx.req.socket() did not honor the Expect: 100-continue request header and could hang. thanks Matthieu Tourne for the patch in pull request #107.
  • bugfix: the ngx.req.socket() object (i.e., the downstream cosocket object) did not work with HTTP 1.1 pipelined requests at all.

• upgraded Lua Nginx Module to 0.5.0rc27.
  • bugfix: nginx could crash on request finalization when running the cosocket cleanup handle due to the lack of check of the ctx pointer. thanks shaneeb for reporting this in github issue #110.
  • bugfix: ngx.req.get_body_data() could not handle multi-buffer request bodies and discarded the body data after the first buffer.
  • bugfix: ngx.ctx was not accessible at all in set_by_lua*. thanks Pierre.
  • bugfix: fixed typo "on-array", which should be "non-array", in an error message.
  • optimize: now ngx.log is much faster when the log level argument is lower than the actual error_log level specified in nginx.conf. thanks Matthieu Tourne for providing the patch.
  • optimize: now we call ngx_http_lua_socket_finalize in cosocket:setkeepalive() to help buffer reuse.
• upgraded Set Misc Nginx Module to 0.22rc8.
  • feature: added new directives set_secure_random_alphanum and set_secure_random_lcalpha|http://wiki.nginx.org/HttpSetMiscModule#set_secure_random_lcalpha for generating cryptographically strong random strings based on the /dev/urandom device. thanks Jeremy Wohl for the patch.
• upgraded Srcache Nginx Module to 0.13rc8.
  • bugfix: the Content-Length response header for HEAD requests should leave intact when cache hits happen.
  • bugfix: the srcache_store subrequest did not set the Content-Length request header properly for multi-buffer request bodies. thanks Feibo Lee for submitting the patch.

• upgraded Lua Redis Parser Library to v0.09.
  • feature: added redis.parser._VERSION.
  • bugfix: now we use Lua userdata to allocate memory used on the C side to prevent potential leaks caused by malloc/free, as discussed in github issue #6.
• upgraded Lua Rds Parser Library to 0.05.
  • feature: added redis.parser._VERSION.
  • bugfix: now we use Lua userdata to allocate memory used on the C side to prevent potential leaks caused by malloc/free, as discussed in github issue #6.
• upgraded Lua Resty Memcached Library to 0.07.
  • feature: now the methods for the Memcached storage commands now accept Lua tables as the value argument. thanks Brian Akins for the patch.
• upgraded Lua Resty Upload Library to 0.03.
  • feature: now the raw headers for each part are also returned, as suggested by zou2062 in github issue #1.
• applied the patch for a bug in ngx_http_named_location to the nginx core: http://mailman.nginx.org/pipermail/nginx-devel/2012-May/002166.html

Mainline Version 1.0.15.1 - 29 April 2012

• upgraded the Nginx core to 1.0.15.
• bugfix: now we also add <openresty_prefix>/lualib/?/init.lua to the default package.path search list. thanks bigplum for reporting this issue.
• upgraded Lua Nginx Module to 0.5.0rc25.
  • bugfix: cosocket connections from the connection pool might lead to segfaults if it is not used immediately. thanks xukaifu for reporting this as github issue #108.
  • bugfix: debug logging in the cosocket receive line method could lead to invalid memory reads under extreme network conditions. this issue was caught by mockeagain in reading mode.
  • bugfix: downstream cosockets might hang on the receive(size) method call for slow connections. mockeagain in reading mode caught this issue.
  • bugfix: we no longer forcibly quit the lua threads by clearing out its environment and running it blindly to the end because Lua GC will collect all those unfinished coroutines anyway.
  • bugfix: improved the longjmp handling when Lua panic happens.
  • bugfix: certain compilers might complain about missing declarations for types like int8_t. now we explicitly included stdint.h. thanks runner-mei for reporting it in github issue #98.
  • feature: added new constant ngx.HTTP_OPTIONS for the HTTP OPTIONS method.
  • feature: added support for OPTIONS method in the subrequest capture APIs. thanks Jónas Tryggvi Jóhannsson for requesting this in github issue #102.
  • feature: added publich C functions ngx_http_lua_add_package_preload, ngx_http_lua_get_global_state, and ngx_http_lua_get_request to help other Nginx C modules expose new functionalities to Lua Nginx Module. thanks Brian Akins for suggesting them in github pull request #101.
  • feature: made ngx_http_lua_api.h visible to other Nginx modules by adding src/api/ to the CORE_INCS config variable value in the config file. thanks Brian Akins for suggesting this in github pull request #105.
  • feature: add the gdbinit script to ease Lua user code debugging (Wang Xiaozhe).
  • optimize: various optimizations in cosocket's timeout handling. this gives about 2.5+% performance boost in some benchmarks using Lua Resty Redis Library and Lua Resty MySQL Library.
• upgraded Rds Json Nginx Module to v0.12rc8.
  • bugfix: Microsoft C compilers complained about missing declarations of the type int8_t. now we explicitly include stdint.h. thanks runner-mei for reporting this issue in github issue #3.
• upgraded Set Misc Nginx Module to 0.22rc7.
  • bugfix: we should omit the set_sha1 directive when we do not have any SHA1 libraries (including OpenSSL) installed. thanks runner-mei for reporting this in github issue #9.
  • feature: added new config directive set_rotate.
• upgraded Drizzle Nginx Module to 0.1.2rc7.
  • bugfix: reading data on a reused MySQL connection (coming from the connection pool) could hang due to the inactive read event when poll event API is used in nginx.
• upgraded Lua Resty MySQL Library to 0.07.
  • fixed a typo in error messages.
  • skipped parsing those column fields that we do not use (yet). this makes things noticeably faster.
