+Before you open a new issue, please search the internet and make sure it is not duplicate.
+
+Ensure you have provided the following details while reporting a problem:
+
+- [ ] The exact version of the related software, including but not limited to the OpenResty version
+(if any), the NGINX core version, the `ngx_lua` module version(via `openresty -V` or `nginx -V`),
+and your operating system version(via `uname -a`).
+- [ ] **A minimal and standalone test case** that others can easily run on their side and
+reproduce the issue you are seeing.
+- [ ] Do not simply say "something is broken" or "something does not work". Always provide
+as much details as possible. Always describe **the symptoms and your expected results**.
+
+You can (temporarily) enable the nginx debugging logs to see the internal workings
+of NGINX in your nginx''s `error.log` file. See http://nginx.org/en/docs/debugging_log.html
+The same instructions apply equally well to OpenResty.
+
+If you are seeing crashes, please provide the full backtrace for the crash. See
+https://www.nginx.com/resources/wiki/start/topics/tutorials/debugging/#core-dump
+for more details.

+
+Release 8 of PCRE is distributed under the terms of the "BSD" licence, as

+directory, is distributed under the same terms as the software itself. The data
+in the testdata directory is not copyrighted and is in the public domain.
+
+The basic library functions are written in C and are freestanding. Also
+included in the distribution is a set of C++ wrapper functions, and a
+just-in-time compiler that can be used to optimize pattern matching. These
+are both optional features that can be omitted when the library is built.

+Additional Features
+===================
+
+In additional to the standard nginx core features, this bundle also supports the following:
+
+[Back to TOC](#table-of-contents)
+
+resolv.conf parsing
+--------------------
+
+**syntax:** *resolver address ... [valid=time] [ipv6=on|off] [local=on|off|path]*
+
+**default:** *-*
+
+**context:** *http, stream, server, location*
+
+Similar to the [`resolver` directive](https://nginx.org/en/docs/http/ngx_http_core_module.html#resolver)
+in standard nginx core with additional support for parsing additional resolvers from the `resolv.conf` file
+format.
+
+When `local=on`, the standard path of `/etc/resolv.conf` will be used. You may also specify arbitrary
+path to be used for parsing, for example: `local=/tmp/test.conf`.
+
+When `local=off`, parsing will be disabled (this is the default).
+
+This feature is not available on Windows platforms.

-README-win32 - README for the Windows 32-bit build of OpenResty
-
-Description
-===========
-
-The official binary Win32 distribution of OpenResty can be downloaded from the following web page:
-
-https://openresty.org/en/download.html
-
-To start the NGINX server of the nginx server of the Win32 binary distribution of OpenResty:
-
-```bash
-start nginx
-```
-
-You can also specify the `-p PATH/` option to override the default server prefix, as in
-
-```bash
-cd /path/to/my/openresty/app/
-start nginx -p $PWD
-```
-
-Then you can use the `tasklist` command to check the nginx processes running in the background:
-
-```console
-C:\> tasklist /fi "imagename eq nginx.exe"
-
-Image Name                     PID Session Name        Session#    Mem Usage
-========================= ======== ================ =========== ============
-nginx.exe                     4616 Console                    1      7,412 K
-nginx.exe                     5836 Console                    1      7,800 K
-
-```
-
-One of the two processes is the master process while the other is the worker.
-
-If you are using the MSYS bash instead of the `cmd.exe` console, then you should replace the `/fi` option
-with `-fi` in the command above instead.
-
-You can quickly shut down the server like this:
-
-```bash
-nginx -s stop
-```
-
-or gracefully shut it down like this:
-
-```bash
-nginx -s quit
-```
-
-You can also forcibly kill the nginx processes via their PIDs with `taskkill`, as in
-
-```console
-C:\> taskkill /pid 5488 /F
-```
-
-where the PID (5488 in this example) can be found via the aforementioned `tasklist` command.
-
-Again, you should use the form `-pid` and `-F` for the options if you are in an MSYS bash
-session.
-
-Similarly, you can use the `nginx -s reload` command to reload nginx configurations without
-stopping the server. And you can use `nginx -s reopen` to instruct nginx to re-open
-all the log files.
-
-You can run the `resty` script like this:
-
-```console
-C:\> resty -e "ngx.say('Hello, OpenResty!')"
-Hello, OpenResty!
-```
-
-The `resty` command-line utility requires a Perl interpreter installed in your
-system and visible to your PATH environment. Any perl distributions should
-work, including StrawberryPerl, ActivePerl, and MSYS perl (the former two are
-recommended though).
-
-Debugging
-=========
-
-Debug symbosl are enabled even in release builds. So that when things go very wrong,
-one can still debug things with tools like MSYS GDB.
-
-Inclusion of debug symbols make the binary files (`.exe` and `.dll` files) much larger,
-but it generally will not load into memory during normal execution on a modern operating
-system.
-
-Caveats
-=======
-
-The Win32 port of the NGINX core supports the good old `select` IO multiplexing mechanism
-only.
-The I/O Completion Ports (IOCP) feature is *not* supported (yet). So do not use this build
-for production environments with very high concurrency levels.
-
-This Win32 build of OpenResty is mainly for developers who want to develop their applications
-in native Windows environment (though they eventually push the finished work onto a Linux or *BSD box, most of the time).
-
-TODO
-====
-
-* Add support for more than one NGINX worker processes.
-* Add support for concurrent connections more than 1024.
-* Switch to the Microsoft Visual Studio compiler toolchain for better performance and easier binary
-package redistribution.
-* Bundle StrawberryPerl to make command-line utilities like `resty` work out of the box (without
-manually installing a Perl).
-* Deliver an alternative Win32 binary package built with best debuggin capabilities (like enabling
-NGINX debugging logs, disabling C compiler optimizations, and enabling all the assertions and checks).
-* Deliver binary packages for 64-bit Windows (Win64).
-
-Details About The Building Process
-==================================
-
-Usually you do not need to worry about how the Win32 binaries were built on the maintainers''
-side. But if you do, please read on.
-
-The Win32 build of OpenResty is currently built via the MinGW/MSYS toolchain, including
-MinGW gcc 4.8.1, MSYS perl, MSYS bash, MSYS make, and etc. Basically, it is currently built via
- the following cmmands:
-
-```bash

+Resolver: ignore ipv6=off resolver option when no ipv6 support
+
+Makes the resolver directive more robust: we only error out when ipv6
+resolution is desired but not supported (ipv6=on).
+
+use case 1: some configurations are sometimes re-used between builds with and
+without ipv6 support. This patch avoids the need to remove the "ipv6=off" flag.
+
+use case 2: currently, some tools rely on the --with-ipv6 configure option from
+"nginx -V" to determine if ipv6 resolution should be disabled in some cases.
+With this option disappearing in Nginx 1.11.5, this patch would allow such tools
+to assume "ipv6=off" to be safe regardless of ipv6 support in the current
+build.

+SSL: handled SSL_CTX_set_cert_cb() callback yielding.
+
+OpenSSL 1.0.2+ introduces SSL_CTX_set_cert_cb() to allow custom
+callbacks to serve the SSL certificiates and private keys dynamically
+and lazily. The callbacks may yield for nonblocking I/O or sleeping.
+Here we added support for such usage in NGINX 3rd-party modules
+(like ngx_lua) in NGINX's event handlers for downstream SSL
+connections.

+Resolver: ignore ipv6=off resolver option when no ipv6 support
+
+Makes the resolver directive more robust: we only error out when ipv6
+resolution is desired but not supported (ipv6=on).
+
+use case 1: some configurations are sometimes re-used between builds with and
+without ipv6 support. This patch avoids the need to remove the "ipv6=off" flag.
+
+use case 2: currently, some tools rely on the --with-ipv6 configure option from
+"nginx -V" to determine if ipv6 resolution should be disabled in some cases.
+With this option disappearing in Nginx 1.11.5, this patch would allow such tools
+to assume "ipv6=off" to be safe regardless of ipv6 support in the current
+build.

+SSL: handled SSL_CTX_set_cert_cb() callback yielding.
+
+OpenSSL 1.0.2+ introduces SSL_CTX_set_cert_cb() to allow custom
+callbacks to serve the SSL certificiates and private keys dynamically
+and lazily. The callbacks may yield for nonblocking I/O or sleeping.
+Here we added support for such usage in NGINX 3rd-party modules
+(like ngx_lua) in NGINX's event handlers for downstream SSL
+connections.
