The problem could be related to bpo-43921. I neither have a macOS nor a Windows machine to reproduce and debug the issue. Since I'm cannot reproduce the problem on Linux, I'm unable to debug and fix it.

pablogsal · 2021-05-25T12:54:23Z

I neither have a macOS nor a Windows machine to reproduce and debug the issue.

Can you maybe use a VM for Windows?

erlend-aasland · 2021-05-25T13:03:57Z

I’ll see if I can provoke it on my Mac.

What’s the preferred solution?

Catch the connection failure and skip the test?
Retry connection?
Find the root cause and make sure it never ever happens :)

Maybe 2. is acceptable :)

pablogsal · 2021-05-25T13:07:40Z

Is possible that these are flaky tests but I am afraid this may be something more important so o would prefer to go with 3 ;)

erlend-aasland · 2021-05-25T13:16:27Z

I feared that ;)

Erlend, could you maybe add some context to the messages, unfortunately, I am failing to understand what they mean :(

tiran · 2021-05-25T14:23:12Z

me, too. Did the change of import for timeout setting cause the issue?

erlend-aasland · 2021-05-25T15:08:24Z

Yes, sorry ‘bout the cryptic messages :)

This is against current main branch (I’m not at my computer right now, so I don’t have the git ref). The first two failures came after 328 and 389 runs. Increasing the timeout (using test.support.SHORT_TIMEOUT) made it harder trigging the failure (~500 repetitions).

I’ll try to declutter when I’m back on my computer.

The mock server fails with EPROTOTYPE, thus the client fails with connection refused.

I found similar issues after doing some googling:

This might be the same macOS bug.

pablogsal · 2021-05-29T22:23:07Z

This might be the same macOS bug.

It could be, but the same thing happens on Windows

erlend-aasland · 2021-05-30T06:37:13Z

It could be, but the same thing happens on Windows

Are you sure? All the reports are from macOS CI. Christian mentioned that it could be similar to another ssl test failure that also happen on Windows, but those tracebacks do not match the ones in this issue.

I haven't observed this issue on the CI since GH-26893 through GH-26896 was merged. Marking this as resolved. If anyone disagrees, feel free to reopen :)

http://erickt.github.io/blog/2014/11/19/adventures-in-debugging-a-potential-osx-kernel-bug/ says:

"If we trigger a send while the kernel is in the middle of tearing down the socket, it returns EPROTOTYPE." (instead of ECONNRESET)

Maybe send() could raise a ConnectionResetError exception on EPROTOTYPE?

erlend-aasland · 2021-06-28T08:05:05Z

But here, it is write() that returns EPROTOTYPE. See msg394798.
