OpenResty 1.7.7.1 released

Hi folks!

I am happy to announce the new formal release, 1.7.7.1, of the OpenResty
bundle:

http://openresty.org/#Download

In this release, we include many important bug fixes in many
components and some small new features as usual.

One highlight of this release is that the Lua call “ngx.flush(true)”
can now work with nginx core’s “limit_rate” directive and $limit_rate
variable.

Special thanks go to all our contributors and users for making this
happen!

Below is the complete change log for this release, as compared to the
last formal release (1.7.4.1):

  • upgraded the Nginx core to 1.7.7.

  • bugfix: applied a patch to the nginx core to fix the memory
    invalid reads when exceeding the pre-configured limits in an
    “ngx_hash_t” hash table.

  • bugfix: applied a patch to the nginx core to fix a memory
    invalid read regression introduced in nginx 1.7.5+'s resolver.

  • ./configure: usage text: renamed “–with-luajit=PATH” to
    “–with-luajit=DIR”. thanks Dominic for the suggestion.

  • feature: ./configure: added the default prefix value to the
    usage text.

  • upgraded LuaJIT to v2.1-20141128:

    • imported Mike Pall’s latest changes:

      • feature: FFI: added “ffi.typeinfo()”. thanks to Peter
        Colberg.

      • bugfix: fixed snapshot #0 handling for traces with a
        stack check on entry. this bug might lead to bad
        register overwrites (and eventually segmentation faults
        in GC upon trace exits, at least).

      • bugfix: FFI: no meta fallback when indexing pointer to
        incomplete struct.

      • bugfix: fixed fused constant loads under high register
        pressure.

      • bugfix: fixed DragonFly build (unsupported). thanks to
        Robin Hahling, Alex Hornung, and Joris Giovannangeli.

      • bugfix: FFI: fixed initialization of unions of subtypes.
        thanks to Peter Colberg.

      • bugfix: FFI: Fix for cdata vs. non-cdata arithmetic and
        comparisons. thanks to Roman Tsisyk.

      • optimize: eliminated hmask guard for forwarded HREFK.

    • debugging: added an (expensive) assertion to check GC
      objects in current stack upon trace exiting. thanks Mike
      Pall. only enabled when building with “-DLUA_USE_ASSERT”.

  • upgraded the ngx_lua module to 0.9.13.

    • optimize: reduced the pool size of a fake connection from
      the default pool size (16KB) to 128B, affecting
      init_worker_by_lua and ngx.timer.at.

    • optimize: made fake requests share their connection pools,
      affecting init_worker_by_lua and ngx.timer.at.

    • feature: the error logger used by ngx.timer.at handlers now
      outputs the “client: xxx, server: xxx” context info for the
      original (true) request creating the timer.

    • feature: added nginx configuration file names and line
      numbers to the rewrite/access/content/log_by_lua directives’
      Lua chunk names in order to simplify debugging.

    • feature: ngx.flush(true) now returns the “timeout” and
      “client aborted” errors to the Lua land for the cases that
      writing to the client is timed out or the client closes the
      connection prematurely, respectively.

    • feature: ngx.flush(true) can now wait on delayed events due
      to nginx’s limit_rate config directive or $limit_rate
      variable settings. thanks Shafreeck Sea for the original
      patch.

    • bugfix: ngx.flush(), ngx.eof(), and some other things did
      not update busy/free chains after calling the output
      filters.

    • bugfix: ngx_gzip/ngx_gunzip module filters might cause
      ngx.flush(true) to hang until timeout for nginx 1.7.7+ (and
      some other old versions of nginx). thanks Maxim D. for
      the help.

    • bugfix: ngx.get_phase() did not work in the context of
      init_worker_by_lua*.

    • bugfix: use of ngx.flush(true) with the limit_rate config
      directive or the $limit_rate variable may hang the request
      forever for large volumn of output data. thanks Shafreeck
      Sea for the report.

    • bugfix: compilation error when PCRE is disabled in the nginx
      build. thanks Ivan Cekov for the report.

    • bugfix: when syslog was enabled in the error_log directive
      for nginx 1.7.1+, use of init_worker_by_lua or
      ngx.timer.at() would lead to segmentation faults. thanks
      shun.zhang for the report.

    • bugfix: fixed compilation error with nginx 1.7.5+ because
      nginx 1.7.5+ changes the API in the events subsystem. thanks
      Charles R. Portwood II and Mathieu Le Marec for the report.

    • bugfix: ngx.req.raw_header(): buffer overflow and the
      “buffer error” exception might happen for massively
      pipelined downstream requests. thanks Dane Knecht for the
      report.

    • bugfix: ngx.req.raw_header(): we might change nginx’s
      internal buffer pointers, which might cause bad
      side-effects.

    • doc: added a new section, Cocockets Not Available
      Everywhere, under the Known Issues section.

  • upgraded the lua-resty-dns library to 0.14.

    • feature: added support for the SPF record type specified by
      RFC 4408. thanks Tom Fitzhenry for the patch.
  • upgraded the lua-resty-lrucache library to 0.03.

    • feature: the get() method now also returns the stale value
      as the second returned value if available.
  • upgraded the lua-resty-lock library to 0.04.

    • bugfix: the shared dictionary would incorrectly get unref’d
      for multiple times when the lock() and/or unlock() methods
      are called more than once. thanks Peng Wu for the report and
      Dejiang Zhu for the patch.
  • upgraded the ngx_echo module to 0.57.

    • bugfix: $echo_client_request_headers: buffer overflow and
      the “buffer error” exception might happen for massively
      pipelined downstream requests.

    • bugfix: $echo_client_request_headers: we might change
      nginx’s internal buffer pointers, which might cause bad
      side-effects.

  • upgraded the ngx_drizzle module to 0.1.8.

    • bugfix: fixed compilation error with nginx 1.7.5+ because
      nginx 1.7.5+ changes the API in the events subsystem.
  • upgraded the ngx_postgres module to 1.0rc5.

    • bugfix: fixed compilation error with nginx 1.7.5+ because
      nginx 1.7.5+ changes the API in the events subsystem.
  • upgraded the ngx_coolkit module to 0.2rc2.

    • bugfix: compilation failed when PCRE was disabled in the
      nginx build.

    • feature: added the “$location” variable, by Piotr S…

  • upgraded the ngx_set_misc module to 0.27.

    • bugfix: bugfix: fixed build failure when
      “–with-mail_ssl_module” is specified while
      “–with-http_ssl_module” is not. thanks Xiaochen Wang for
      the report.

OpenResty (aka. ngx_openresty) is a full-fledged web application
server by bundling the standard Nginx core, Lua/LuaJIT, 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:

Enjoy!
