                            <comment id="1474798" author="jesse" created="Wed, 11 Jan 2017 17:59:42 +0000"  >&lt;p&gt;Thanks for reporting and investigating, Remi. I can reproduce this: if I run mongod locally with IPv6 turned off, I fail at the same spot, where test_command() tries to call ismaster on localhost:27017.&lt;/p&gt;

&lt;p&gt;We didn&apos;t catch this because we habitually pass &quot;--ipv6&quot; to our test mongod instance when we run the tests.&lt;/p&gt;

&lt;p&gt;The problem is in mongoc_topology_scanner_node_connect_tcp where we initially discover which servers from the host list are available. There, we call getaddrinfo with AF_UNSPEC (this is a change, it had been AF_INET). On my Mac and most machines, the IPv6 result for &quot;localhost&quot; is returned at the beginning of the results, followed by the IPv4 result. The driver chooses the first result and tries to connect, with a default timeout of 10 seconds. If that fails, it considers the host unavailable. It does *&lt;b&gt;not&lt;/b&gt;* attempt to connect using the other results from the getaddrinfo list.&lt;/p&gt;

&lt;p&gt;The test passes if mongod is started with --ipv6. However, any tests using mock_server_t fail, since the mock server doesn&apos;t listen on IPv6. The such test is test_cooldown_rs(), so that fails once we have mongod listening on IPv6.&lt;/p&gt;

&lt;p&gt;Right now we should revert the change, as you proposed.&lt;/p&gt;

&lt;p&gt;There are two options for a long-term solution:&lt;/p&gt;

&lt;p&gt;1. After a connection times out, we should reset the connect timer and try the next getaddrinfo result.&lt;br/&gt;
2. Implement something akin to &quot;Happy Eyeballs&quot;: try all addresses returned by getaddrinfo concurrently and use the first connection that succeeds. Cache the address that succeeded (IPv4 or IPv6 or whatever) and use that for subsequent connections to the same host:port until some cache duration times out.&lt;/p&gt;

&lt;p&gt;Number 2 shouldn&apos;t be very hard, since the topology scanner is already parallel across multiple hosts, it just needs to become parallel across multiple addresses for each host.&lt;/p&gt;</comment>
                            <comment id="1474299" author="remi" created="Wed, 11 Jan 2017 10:23:22 +0000"  >&lt;p&gt;Final try: simply revert &lt;a href=&quot;https://github.com/mongodb/mongo-c-driver/commit/333cbc2cd2f54f3650f51c39a2490c28c355cc0f&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo-c-driver/commit/333cbc2cd2f54f3650f51c39a2490c28c355cc0f&lt;/a&gt;&lt;br/&gt;
Everything works.&lt;/p&gt;
