高性能 Web 平台 OpenResty v1.11.2.1 发布

   <p style="text-align:center"><img alt="" src="https://simg.open-open.com/show/376b281b363f1d680abe171c87bbcb53.jpg" /></p>    <p>OpenResty 是一个基于 Nginx 与 Lua 的高性能 Web 平台，其内部集成了大量精良的 Lua 库、第三方模块以及大多数的依赖项。用于方便地搭建能够处理超高并发、扩展性极高的动态 Web 应用、Web 服务和动态网关。</p>    <p> </p>    <p>OpenResty 通过汇聚各种设计精良的 Nginx 模块（主要由 OpenResty 团队自主开发），从而将 Nginx 有效地变成一个强大的通用 Web 应用平台。这样，Web 开发人员和系统工程师可以使用 Lua 脚本语言调动 Nginx 支持的各种 C 以及 Lua 模块，快速构造出足以胜任 10K 乃至 1000K 以上单机并发连接的高性能 Web 应用系统。</p>    <p> </p>    <p>OpenResty 的目标是让你的Web服务直接跑在 Nginx 服务内部，充分利用 Nginx 的非阻塞 I/O 模型，不仅仅对 HTTP 客户端请求,甚至于对远程后端诸如 MySQL、PostgreSQL、Memcached 以及 Redis 等都进行一致的高性能响应。</p>    <p style="text-align:center"><img alt="" src="https://simg.open-open.com/show/3a8e45dde239a18bc97a8524f9dd217b.png" /></p>    <h2>更新日志</h2>    <ul>     <li>upgraded the <a href="/misc/goto?guid=4958993389596333579">Nginx</a> core to 1.11.2.      <ul>       <li>see the changes here: <a href="/misc/goto?guid=4958186202159580904">http://nginx.org/en/CHANGES</a></li>      </ul> </li>     <li>feature: bundled the sess_set_get_cb_yield patch for OpenSSL to support the <a href="/misc/goto?guid=4958993389757441971">ssl_session_fetch_by_lua*</a> directives of <a href="/misc/goto?guid=4958993389899327717">ngx_lua</a>.</li>     <li>win32: we now use pcre 8.39 and openssl 1.0.2h in our official build.</li>     <li>feature: applied the <code>ssl_pending_session.patch</code> to the <a href="/misc/goto?guid=4958993389596333579">nginx</a> core to support the <a href="/misc/goto?guid=4958993389757441971">ssl_session_fetch_by_lua*</a> and <a href="/misc/goto?guid=4958993390064577105">ssl_session_store_by_lua*</a> in <a href="/misc/goto?guid=4958993389899327717">ngx_lua</a>.</li>     <li>feature: added <code><openresty-prefix>/site/lualib/</code> to the default Lua module search paths used by OpenResty. This location is for 3rd-party Lua modules so that the users will not pollute the <code><openresty-prefix>/lualib/</code> directory with non-standard Lua module files.</li>     <li>feature: now we create the <code><openresty-prefix>/bin/openresty</code> symlink which points to <code><openresty-prefix>/nginx/sbin/nginx</code> to avoid polluting the <code>PATH</code>environment with the name "nginx".</li>     <li>feature: added the <code>upstream_timeout_fields</code> patch to the <a href="/misc/goto?guid=4958993389596333579">nginx</a> core to allow efficient per-request connect/send/read timeout settings for individual upstream requests and retries.</li>     <li>feature: added the official LuaJIT documentation from LuaJIT 2.1 to our <code>restydoc</code> indexes.</li>     <li>feature: added the Lua 5.1 reference manual from lua 5.1.5 to our restydoc indexes.</li>     <li>bugfix: special characters like spaces in <a href="/misc/goto?guid=4958993389596333579">nginx</a> configure option values (like <code>--with-pcre-opt</code> and <code>--with-openssl-opt</code>) were not passed correctly. thanks Andreas Lubbe for the report.</li>     <li>change: now we use our own version of default <code>index.html</code> and <code>50x.html</code> pages.</li>     <li>upgraded <a href="/misc/goto?guid=4958993389899327717">ngx_lua</a> to 0.10.6.      <ul>       <li>feature: added new shdict methods: <a href="/misc/goto?guid=4958993390260471133">lpush</a>, <a href="/misc/goto?guid=4958993390394479351">lpop</a>, <a href="/misc/goto?guid=4958993390527080670">rpush</a>, <a href="/misc/goto?guid=4958993390648983802">rpop</a>, <a href="/misc/goto?guid=4958993390786528216">llen</a> for manipulating list-typed values. these methods can be used in the same way as the redis commands of the same names. Essentially we now have shared memory based queues now. each queue is indexed by a key. thanks Dejiang Zhu for the patch.</li>       <li>feature: implemented <a href="/misc/goto?guid=4958993389757441971">ssl_session_fetch_by_lua*</a> and <a href="/misc/goto?guid=4958993390064577105">ssl_session_store_by_lua*</a> configuration directives for doing (distributed) caching of SSL sessions (via SSL session IDs) for downstream connections. thanks Zi Lin for the patches.</li>       <li>feature: added pure C API for setting upstream request connect/send/read timeouts in <a href="/misc/goto?guid=4958993390956540943">balancer_by_lua*</a> on a per session basis. thanks Jianhao Dai for the original patch.</li>       <li>feature: ssl: add <a href="/misc/goto?guid=4958993391081707470">FFI</a> functions to parse certs and private keys to cdata. With the current <a href="/misc/goto?guid=4958993391081707470">FFI</a> functions the certificate chain and the private key are parsed from DER every time they are set into the SSL state. Now we can cache the parsed certs and private keys as cdata objects directly. These new functions make it possible to avoid the DER -> OpenSSL parsing. Thanks Alessandro Ghedini for the patch.</li>       <li>feature: <a href="/misc/goto?guid=4958993391232522778">shdict:incr()</a>: added the optional <code>init</code> argument to allow intializing nonexistent keys with an initial value.</li>       <li>feature: allow <a href="/misc/goto?guid=4958976214061621226">tcpsock:setkeepalive()</a> to receive nil args. thanks Thibault Charbonnier for the patch.</li>       <li>bugfix: <code>*_by_lua_file</code>: did not support absolute file paths on non-UNIX systems like Win32. thanks Someguynamedpie for the report and the original patch.</li>       <li>bugfix: fake connections did not carry a proper connection number. thanks Piotr Sikora for the patch.</li>       <li>bugfix: "lua_check_client_abort on" broke HTTP/2 requests.</li>       <li>bugfix: <code>ngx_http_lua_ffi_ssl_create_ocsp_request</code>: we did not clear the openssl stack errors in the right place.</li>       <li>bugfix: <a href="/misc/goto?guid=4958993391400466972">ngx.sha1_bin()</a> was always disabled with <a href="/misc/goto?guid=4958993389596333579">nginx</a> 1.11.2+ due to incompatible changes in <a href="/misc/goto?guid=4958993389596333579">nginx</a> 1.11.2+. thanks manwe for the report.</li>       <li>bugfix: segfaults might happen when calling <a href="/misc/goto?guid=4958993391567242067">ngx.log()</a> in <a href="/misc/goto?guid=4958993391689024031">ssl_certificate_by_lua*</a> and error_log was configured with syslog. thanks Jonathan Serafini and Greg Karékinian for the report.</li>       <li>bugfix: fixed a typo in the error handling of the <code>SSL_get_ex_new_index()</code> call for our ssl ctx index. thanks Jie Chen for the report.</li>       <li>bugfix: when the <a href="/misc/goto?guid=4958993389596333579">nginx</a> core does not properly initialize <code>r->headers_in.headers</code> (due to 400 bad requests and

0.1.8.      <ul>       <li>updated the <code>resty.core.shdict</code> Lua module to reflect the recent addition of list-typed shdict values in <a
