Hello folks! I am happy to announce that the new mainline version of ngx\_openresty, 1.4.3.7, is now released: ``` http://openresty.org/#Download ``` Thanks all our contributors for making this happen! The highlights of this release are the new LuaJIT v2.1 engine and the lua-resty-core library. You should observe immediate speedup in your existing OpenResty/Lua apps after upgrading to this version. Sometimes the speedup can be 40% overall, as observed in CloudFlare’s Lua WAF system. Sometimes it may just be 10%, as observed in CloudFlare’s Lua CDN system. Thanks to all the new improvements in LuaJIT v2.1, especially the improvements in the JIT compiler; Mike Pall is my hero 😉 Special thanks go to CloudFlare for kindly sponsoring 3 development phases in LuaJIT v2.1 (and phase #4 is also coming!). The lua-resty-core library reimplements many Lua API functions provided by the ngx\_lua module with LuaJIT FFI, which means user Lua code paths using these API functions can finally be JIT compiled by LuaJIT (they used to be interpreted by LuaJIT’s interpreter only). So enabling lua-resty-core like below in nginx.conf may give another speedup in your Lua applications: ``` init_by_lua ' require "resty.core" '; ``` Loading the resty.core module will replace a lot of ngx\_lua’s Lua API functions with resty.core’s own FFI-based implementations. So you can easily compare the performance with and without lua-resty-core 🙂 Enabling lua-resty-core in CloudFlare’s Lua WAF system gives another 33% ~ 37% overall speedup. Whee! But if your don’t have enough Lua code paths (actually) JIT compiled, you MAY observe slowdown after enabling lua-resty-core. So always benchmark the performance of your app before enabling lua-resty-core in production. Or just resolve or workaround the blockers in your Lua code paths that cannot be JIT compiled, with the aid of LuaJIT’s jit.v or jit.dump modules. To use LuaJIT’s jit.v or jit.dump modules to analyze your Lua apps running in OpenResty/Nginx, you can put the following lines into your nginx.conf’s http {} block: ``` init_by_lua ' local verbose = false if verbose then local dump = require "jit.dump" dump.on("b", "/tmp/jit.log") else local v = require "jit.v" v.on("/tmp/jit.log") end require "resty.core" '; ``` And load your app with tools like ab and weighttp to get your Lua code hot (for LuaJIT’s JIT compiler). Then you can check the outputs in the file /tmp/jit.log for all the detailed information from the JIT compiler. Below is the complete change log for this release, as compared to the last (stable) release, 1.4.3.6: - upgraded LuaJIT to v2.1-20131211. - bundled LuaRestyCoreLibrary 0.0.2. - upgraded LuaNginxModule to 0.9.3. - upgraded HeadersMoreNginxModule to 0.24. - upgraded SetMiscNginxModule to 0.23. - upgraded MemcNginxModule to 0.14. - upgraded RdsJsonNginxModule to 0.13. - upgraded EchoNginxModule to 0.50. - upgraded ArrayVarNginxModule to 0.03. - upgraded RedisNginxModule module to 0.3.7. - feature: applied the larger\_max\_error\_str patch to the nginx core to allow error log messages up to 4096 bytes and to allow the C macro “NGX\_MAX\_ERROR\_STR” to be overridden from the outside. - feature: added new configure option “–with-pcre-conf-opt=OPTIONS” to the nginx core to allow custom PCRE ./configure build options. thanks Lance Li for the original patch. The HTML version of the change log with lots of helpful hyper-links can be browsed here: ``` http://openresty.org/#ChangeLog1004003 ``` 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 run extensive testing on our Amazon EC2 test cluster and ensured that all the components (including the Nginx core) play well together. The latest test report can always be found here: ``` http://qa.openresty.org ``` Have fun! -agentzh ---

Thanks Tor Hveem and lhmwzy for the report! See [OpenResty® - Open source](http://openresty.org/#Download) Best regards, -agentzh ---
