Re: [Libguestfs] Figuring out some failing tests for libnbd

I am preparing more patches for CI to run check-valgrind and fix ongoing errors but there are two issues I can not identify the reason why they are failing. - On debian-10 the info/info-can.sh started failing and the error message is just one of those I saw earlier in other places: libnbd: debug: nbd1: nbd_opt_abort: leave: error="nbd_opt_abort: invalid state: READY: the handle must be negotiating: Invalid argument" - On Fedora rawhide I hit a random issue where a port in a URI was translated to its name and looking at the code I can not find how this could have happened. Until this is fixed the test suite is unreliable and notification fatigue will cause everyone to start ignoring any future failures. /builds/nertpinx/libnbd/tests/.libs/aio-connect: actual URI nbd://127.0.0.1:altova-lm/ != expected URI nbd://127.0.0.1:35355/

- Both openSUSE builds are failing to run check-valgrind and it looks like it might be unrelated to libnbd, although it would be nice for someone else to confirm that. For now I have disabled check-valgrind on those platforms in my branch. - Similarly to openSUSE Ubuntu 20.04 fails in valgrind tests, but somewhere down the GnuTLS rabbit hole, which I presume is unrelated too, so I disabled check-valgrind on that one as well. I will send the patches once they are cleaned up, but I wanted to let everyone know what the current status is because eliminating all random issues is essential to properly consuming CI results.

Thanks, Martin
