---- lua-resty-dns - Lua DNS resolver for the ngx_lua based on the cosocket API
----
---- https://github.com/openresty/lua-resty-dns
----
----# Description
----
---- This Lua library provides a DNS resolver for the ngx_lua nginx module:
----
---- https://github.com/openresty/lua-nginx-module/#readme
----
---- This Lua library takes advantage of ngx_lua's cosocket API, which ensures
---- 100% nonblocking behavior.
----
---- Note that at least [ngx_lua 0.5.12](https://github.com/openresty/lua-nginx-module/tags) or [OpenResty 1.2.1.11](http://openresty.org/#Download) is required.
----
---- Also, the [bit library](http://bitop.luajit.org/) is also required. If you're using LuaJIT 2.0 with ngx_lua, then the `bit` library is already available by default.
----
---- Note that, this library is bundled and enabled by default in the [OpenResty bundle](http://openresty.org/).
----
---- IMPORTANT: to be able to generate unique ids, the random generator must be properly seeded using `math.randomseed` prior to using this module.
----
----# Automatic Error Logging
----
---- By default, the underlying [ngx_lua](https://github.com/openresty/lua-nginx-module/#readme) module does error logging when socket errors happen. If you are already doing proper error handling in your own Lua code, then you are recommended to disable this automatic error logging by turning off [ngx_lua](https://github.com/openresty/lua-nginx-module/#readme)'s [lua_socket_log_errors](https://github.com/openresty/lua-nginx-module/#lua_socket_log_errors) directive, that is:
----
----```nginx
----    lua_socket_log_errors off;
----```
----
----# Limitations
----
---- * This library cannot be used in code contexts like `set_by_lua*`, `log_by_lua*`, and `header_filter_by_lua*` where the ngx_lua cosocket API is not available.
---- * The `resty.dns.resolver` object instance cannot be stored in a Lua variable at the Lua module level, because it will then be shared by all the concurrent requests handled by the same nginx worker process (see https://github.com/openresty/lua-nginx-module/#data-sharing-within-an-nginx-worker ) and result in bad race conditions when concurrent requests are trying to use the same `resty.dns.resolver` instance. You should always initiate `resty.dns.resolver` objects in function local variables or in the `ngx.ctx` table. These places all have their own data copies for each request.

---- The optional parameter `tries` can be provided as an empty table, and will be returned as a third result. The table will be an array with the error message for each (if any) failed try.
----
---- When data truncation happens, the resolver will automatically retry using the TCP transport mode to query the current nameserver. All TCP connections are short lived.
