Description Jonathan Bedard 2023-10-13 09:36:56 PDT

Brianna Fan and I have encountered situations where IPV6 requests time out cause `git-webkit` (and presumably other scripts) to take extremely long to run. In some circumstances, we've been able to work-around this problem by disabling IPV6 for the duration of the program, but unsurprisingly, that can backfire if it's actually IPV4 that's not working. Ultimately, the root cause of this problem seems to be that Python hasn't yet implemented "Happy Eyeballs", https://en.wikipedia.org/wiki/Happy_Eyeballs.

This bug is intended to track mitigations and work-around in WebKit tools for this problem. There are a few things we can do to improve our usage of Python's networking stack in general, ideally we can come up with a hack to solve this generally.
