*** Bug 929827 has been marked as a duplicate of this bug. *** Created attachment 634719 [details] more hangup backtraces from current libzypp-15.2+zypper https://github.com/openSUSE/zypper/pull/69 seems to fix the hangups and segfaults I can still trigger these hangups on current Tumbleweed with zypper-1.12.22-1.1.x86_64 libzypp-15.19.3-1.1.x86_64 Happens e.g. with a wait of 0.9 seconds before the 2nd Ctrl-C (on my fast laptop) zypper-1.13.19 will leave the sighandler on the 2nd Ctrl-C. Back in the normal workflow, it tries to exit ASAP. (More Ctrl-C however will exit immediately from within the handler). Fixed in zypper-1.13.23 After rewriting the tmpdir and temp repo related stuff, there should be no more need for a complex cleanup. Now always using _exit(2) from within the signal handler. This should fix the sporadic crashes on double Ctrl-C. *** Bug 1012597 has been marked as a duplicate of this bug. *** |
Created attachment 633369 [details] backtraces from 2015-05-06 Factory zypper hangups I ran a stress-test script on zypper that started a package download+install and at a random time hit Ctrl-C twice (sent SIGINT) with a random delay between the two. This sometimes caused zypper to get stuck. Then it needed a killall -9 zypper to end it.
