Ngx_openresty devel version released

Hello folks!

I am happy to announce that the new development version of
ngx_openresty,, is now released:

Special thanks go to all the contributors for making this happen!

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

  • upgraded SetMiscNginxModule to 0.22.

    • bugfix: we did not escape “\0”, “\z”, “\b”, and “\t”
      properly in set_quote_sql_str according to the MySQL quoting
      rules. thanks Siddon Tang for the report.
  • upgraded LuaNginxModule to 0.8.8.

    • feature: added new option “always_forward_body” to
      ngx.location.capture() and ngx.location.capture_multi(),
      which controls whether to always forward the parent
      request’s request body to the subrequest (even when the
      subrequest is not of the POST or PUT request method). thanks
      Matthieu T. for the request.

    • feature: now timeout errors in tcpsock:receive() and
      tcpsock:receiveuntil() no longer automatically close the
      current cosocket object (for both upstream and downstream
      connections). thanks Aviram Cohen for the original patch.

    • bugfix: we did not escape “\0”, “\z”, “\t”, and “\b”
      properly in ngx.quote_sql_str(). thanks Siddon Tang for the

    • bugfix: Lua backtrace dumps upon uncaught Lua exceptions did
      not work with the standard Lua 5.1 interpreter when the
      backtrace was deeper than 22 levels.

    • change: now we just dump the top 22 levels in the backtrace
      for uncaught Lua exceptions for the sake of simplicity.

    • change: we now limit the number of nested coroutines in the
      backtrace dump for uncaught Lua exceptions by 5.

    • optimize: grouped the Lua string concatenation operations
      when constructing the backtrace string for uncaught Lua

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:
