`socket.connect` blocks indefinitely in non-blocking mode #382

Open nikneym opened 2 years ago

nikneym commented 2 years ago

socket.connect or connect method blocks indefinitely when network speed or bandwith is low. It also blocks when DNS resolution fails or takes some time. Probably gets blocked at socket_waitfd, not sure if the same is happening on Windows, just checked usocket.c.

Thanks for the report. Unfortunately I am unable to invest much of my spare time in developing this right now, but I thought I'd drop a comment to say that I am available enough to facilitate PRs that fix bugs or add features, so if anybody has time to scratch this itch and fix/improve the library there should be a path to getting it merged and released.

I've made this to deal with the problem in the moment, leaving it here for people who may encounter a similar problem.

Any overlap with #190 and/or #278 here?
