Version highlights

The highlights of this release candidate are:

  • Based on the very recent mainline NGINX core 1.17.8.
  • Support for OpenSSL 1.1.1 by upgrading the OpenSSL patches.
  • Dropped support for PUC-Rio Lua; from now on, only LuaJIT 2.x is supported.
  • Dropped the dtrace and gcc-maybe-uninitialized-warning NGINX core patches, and applied the new init_cycle_pool_release patch. Additionally, all versions of the OpenSSL patches are now bundled in the final release tarball.
  • Reduced the final release tarball size from 4.7MB down to 3.5MB.
  • ngx_lua
    • Mandatorily load lua-resty-core and switched to the FFI-based API when available. Many old CFunction implementations have been removed, and lua_load_resty_core has been deprecated.
    • Made the coroutine.wrap() API propagate errors to its parent coroutine, aligning with standard Lua behavior. This change may be breaking for some applications relying on the previous - but invalid - behavior of ngx_lua.
    • Fixed several compilation errors for static PCRE builds and LuaJIT FFI checks.
  • ngx_stream_lua
    • Ported many features from the ngx_lua module, including:

      • Added the pool_size and backlog options to the tcpsock:connect() API.
      • Enabled many FFI-based APIs for the stream subsystem including ngx.worker.*, ngx.var, ngx.ctx, and many more...
      • Fixed several compilation errors for static PCRE builds and LuaJIT FFI checks.
      • Ported more features and bugfixes from previous releases of the ngx_lua module...
  • lua-resty-core
    • Implemented the new ngx_req.add_header() API, similar to ngx_resp.add_header().
    • New features for the ngx.pipe API with support for environment variables, timeouts, and more.
    • Updated the ngx_ssl.get_tls1_version_str() API to recognize TLS 1.3 connection.
  • LuaJIT
    • Increased the maximum number of allowed upvalues from 60 to 120.
    • Initial support for x390x architectures.
    • Many fixes imported from Mike Pall's upstream LuaJIT repository...
