dns getaddrinfo 资源应及时释放 #6

Open

alexsunday wants to merge 1 commit into hichard:master from alexsunday:getaddrinfo_fix

alexsunday commented Oct 15, 2020

在mqtt_resolve_uri 中，调用了 getaddrinfo，直到 _exit时才释放，但中途mbedtls_client_connect 又会再次使用此函数，此函数不可重入，会直接导致失败。

此处可安全提前释放资源。

之前提交的PR，使用 github 的编辑器，会自动转换 gbk to utf8，不方便查看，故重新提交。


          fix getaddrinfo free bug.

@alexsunday 测试了一下，加上你修改的代码后不能连上MQTT服务器
