Lua Resty Lock Library
Yichun Zhang , 30 Sep 2013 (created 30 Sep 2013)This Lua library implements a simple nonblocking mutex lock API based on Lua Nginx Module's shared memory dictionaries. Mostly useful for eliminating "dog-pile effects".

This library is enabled by default. You can specify the --without-lua_resty_lock
option
to OpenResty's ./configure
script to explicitly disable it.
