OpenResty 1.13.6 发布

upgraded the Nginx core to 1.13.6.
- see the changes here: nginx.org/en/CHANGES
bundled the new component, ngx_stream_lua_module 0.0.4, which is also enabled by default. One can disable this 3rd-party Nginx C module by passing --without-stream_lua_module to the ./configure script. We provide compatible Lua API with ngx_lua wherever it makes sense. Currently we support content_by_lua*, preread_by_lua* (similar to ngx_lua's access_by_lua* ), log_by_lua*, and balancer_by_lua* in the stream subsystem. thanks Mashape Inc. for sponsoring the OpenResty Inc. team to do the development work on rewriting ngx_stream_lua for recent nginx core version.
change: applied a patch to the nginx core to make sure the "server" header in HTTP/2 response shows "openresty" when the server_tokens diretive is turned off.
feature: added nginx core patches needed by ngx_stream_lua_module's balancer_by_lua*.
win32: upgraded PCRE to 8.41.
upgraded ngx_lua to 0.10.11.
- feature: shdict: added pure C API for getting free page size and total capacity for lua-resty-core. thanks Hiroaki Nakamura for the patch.
- feature: added pure C functions for shdict:ttl() and shdict:expire() API functions. thanks Thibault Charbonnier for the patch.
- bugfix: *_by_lua_block directives might break nginx config dump (-T switch). thanks Oleg A. Mamontov for the patch.
- bugfix: segmentation faults might happen when pipelined http requests are used in the downsteram connection. thanks Gao Yan for the report.
- bugfix: the ssl connections might be drained and reused prematurely when ssl_certificate_by_lua* or ssl_session_fetch_by_lua* were used. this might lead to segmentation faults under load. thanks guanglinlv for the report and the original patch.
- bugfix: tcpsock:connect(): when the nginx resolver's send() immediately fails without yielding, we didn't clean up the coroutine ctx state properly. This might lead to segmentation faults. thanks xiaocang for the report and root for the patch.
- bugfix: added fallthrough comment to silence GCC 7's -Wimplicit-fallthrough. thanks Andriy Kornatskyy for the report and spacewander for the patch.
- bugfix: tcpsock:settimeout, tcpsock:settimeouts: throws an error when the timeout argument values overflow. Here we only support timeout values no greater than the max value of a 32 bits integer. thanks spacewander for the patch.
- doc: added "413 Request Entity Too Large" to the possible short circuit response list. thanks Datong Sun for the patch.
upgraded lua-resty-core to 0.1.13.
- feature: ngx.balancer now supports the ngx_stream_lua; also disabled all the other FFI APIs for the stream subsystem for now.
- feature: resty.core.shdict: added new methods shdict:free_space() and shdict:capacity(). thanks Hiroaki Nakamura for the patch.
- feature: implemented the ngx.re.gmatch function with FFI. thanks spacewander for the patch.
- bugfix: ngx.re: fix an edge-case where re.split() might not destroy compiled regexes. thanks Thibault Charbonnier for the patch.
- feature: implemented the shdict:ttl() and shdict:expire() API functions using FFI.
upgraded lua-resty-dns to 0.20.
- feature: allows RRTYPE values larger than 255. thanks Peter Wu for the patch.
upgraded lua-resty-limit-traffic to 0.05.
- feature: added new module resty.limit.count for GitHub API style request count limiting. thanks Ke Zhu for the original patch and Ming Wen for the followup tweaks.
- bugfix: resty.limit.traffic: we might not uncommit previous limiters if a limiter got rejected while committing a state. thanks Thibault Charbonnier for the patch.
- bugfix: resty.limit.conn: we incorrectly specified the exceeded connection count as the initial value for the shdict key decrement which may lead to dead locks when the key has been evicted in very busy systems. thanks bug had appeared in v0.04.
upgraded resty-cli to 0.20.
- feature: resty: impelented the -j off option to turn off the JIT compiler.
- feature: resty: implemented the -j v and -j dump options similar to luajit's.
- feature: resty: added new command-line option -l LIB to mimic lua and luajit -l parameter. thanks Michal Cichra for the patch.
- bugfix: resty: handle SIGPIPE ourselves by simply killing the process. thanks Ingy dot Net for the report.
- bugfix: resty: hot looping Lua scripts failed to respond to the INT signal.
upgraded opm to 0.0.4.
- bugfix: opm: when curl uses HTTP/2 by default opm would complain about "bad response status line received". thanks Donal Byrne and Andrew Redden for the report.
- debug: opm: added more details in the "bad response status line received from server" error.
upgraded ngx_headers_more to 0.33.
- feature: add wildcard match support for more_clear_input_headers.
- doc: fixed more_clear_input_headers usage examples. thanks Daniel Paniagua for the patch.

upgraded ngx_rds_csv to 0.08.
- tests: varous changes in the test suite.
upgraded LuaJIT to v2.1-20171103: github.com/openresty/l…
- optimize: use more appressive JIT compiler parameters as the default to help large OpenResty Lua apps. We now use the following jit.opt defaults: maxtrace=8000 maxrecord=16000 minstitch=3 maxmcode=40960 -- in KB.
