Inconsistant sigsegv on void-musl wsl xbps-install -Su #567

Closed Matthieu-Sauer closed 4 months ago

Matthieu-Sauer commented 1 year ago

I sometimes encounter a segmentation fault when upgrading my wsl void-musl system.

Command used:

xbps-install -Su

Base system:

windows 10 pro
WSL 2 void-linux with musl libc (no glibc compatibility installed)

Re-running the command fixes the issue, therefore I cannot reproduce it to pinpoint the error source. (and I did not take a screenshot of the error, dumb as I am). it is not really annoying as it is fixed in a few seconds.

Is there a way to enable loggings of the xbps suite so I can know exactly where the issue comes from on wsl system (I don't think there is runit services on wsl)? (which package causes it). It happens about once or twice a month, and it seems to be related to python packages, unsure therefore if this is the correct repository to report this?

If the issue is wsl-related, I will simply ignore it (and you can close the issue) as I know it is not the primary target of void and xbps.

Duncaen commented 1 year ago

xbps logs some information to syslog, but its most likely not verbose enough to make any guess to why its segfaulting. The best way to debug segfaults is to enable coredumps or use gdb to get bracktraces of the crashes.

Matthieu-Sauer commented 1 year ago

Understood, I'll try to always use gdb when running xbps (or running valgrind too, might be too slow though)

edit: I did alias my xbps-install with gdb so it is always run whatever the command may be, i'll update this thread if/when I encounter the segmentation fault again.

Matthieu-Sauer commented 1 year ago

I did not encounter the crash again, either gdb is correcting the crash (and that is why I do not witness it anymore) or it has been patched (maybe in the package that was causing it). I will close this issue, and reopen it if I ever have the problem again. (while disabling gdb).

Matthieu-Sauer commented 1 year ago

I actually just encountered the crash. here it is (without gdb sadly).

sudo xbps-install -Su

if I rerun the command, it runs fine.

(here is the display of the second run)
