v3: [Testbot run with this patch](https://testbot.winehq.org/GetFile.pl?JobKey=161972&StepKey=1) - Add test if "stored" event gets reset with connect attempts with invalid address/size. - Move the event clearing after the call to sockaddr_to_unix. TODO: - Add test: "I.e. if you fail connection, don't check events, and then successfully connect, I would expect that the connection failure is not reported. Ideally this too should be tested." -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10044#note_129973

Hello Elizabeth, thanks for your great feedback. I pushed v2 that addresses a few of the raised issues. But I have trouble adding the additional tests. What would an invalid address look like? Cases where sockaddr_to_unix returns zero. It's probably enough to test just one such case, e.g. if the address length is too small, or if the family is invalid. Thanks for the clarification. I added this in v3, and therefore moved in the implementation the event resetting below the call to sockaddr_to_unix.
For the test about the "successful connect": In this [Testbot run](https://testbot.winehq.org/JobDetails.pl?Key=161973) I added a connect to an open port, but I receive WSAEALREADY from native, when there is an event stored before. Is this somewhere near what you wanted to see? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10044#note_129980

Is this somewhere near what you wanted to see? Your previous connect hasn't had time to resolve to a failure state yet. The socket is only connectable again once it's clear that it's actually failed to connect. You'll probably want to use a select() or WSAPoll() in order to wait for that to happen, before doing the event tests.
