[Bug 887946] Re: Deadlocks in main loop
** Description changed: Some applications get stuck in a deadlock when utilizing glib. One of examples is lrmadmin, when connecting to lrmd. Upstream provided a fix for this bug and Ubuntu's version 11.04 and newer do not have this issue. Ubuntu 10.04 and 10.10 do not contain the fix. Upstream fix: + https://mail.gnome.org/archives/commits-list/2010-November/msg01816.html - https://mail.gnome.org/archives/commits-list/2010-November/msg01816.html + [Impact] + Remove potential and demonstratable deadlocks in glib code. + + [Test Case] + * Install lucid + * add ubuntu-ha-maintainers lucid ppa and update repo: +apt-add-repository ppa:ubuntu-ha-maintainers/lucid-cluster ; apt-get update + * Install pacemaker: +apt-get -y install pacemaker + * Enable corosync (/etc/default/corosync) and start it: +sed -i -e 's/START=no/START=yes/' /etc/default/corosync +service corosync start + * Open two client-server connections: +lrmadmin -C ; lrmadmin -C +It deadlocks on second run (it actually never finishes the first run). + + * Kill lrmd and stop corosync: +killall -9 lrmd ; service corosync stop + * install fix +apt-get update apt-get install libglib2.0-0 + * Start corosync: +service corosync start + * Run the test again: +lrmadmin -C ; lrmadmin -C ; lrmadmin -C ; lrmadmin -C + * It doesn't deadlock. + + [Regression Potential] + Regression potential should be very small. This change is still present in almost unmodified upstream code to this day (g_source_unref_internal of glib/gmain.c). The upstream trunk commit is at http://git.gnome.org/browse/glib/commit/?id=b358202856682e5cdefb0b4b8aaed3a45d9a85fa . ** Summary changed: - Deadlocks in main loop + [SRU] Deadlocks in main loop -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/887946 Title: [SRU] Deadlocks in main loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/887946/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I'm unsubscribing ubuntu-sponsors from this bug. Merge-proposals requesting a review from ubuntu-sponsors or ubuntu-branches (the default) automatically show up in our queue for sponsorship.

Test case: Install lucid add ubuntu-ha-maintainers lucid ppa and update repo: apt-add-repository ppa:ubuntu-ha-maintainers/lucid-cluster ; apt-get update Install pacemaker: apt-get -y install pacemaker Enable corosync (/etc/default/corosync) and start it: sed -i -e 's/START=no/START=yes/' /etc/default/corosync ; \ service corosync start Open two client-server connections: lrmadmin -C ; lrmadmin -C It deadlocks on second run (it actually never finishes the first run). Kill lrmd and stop corosync: killall -9 lrmd ; service corosync stop Add ppa:ivoks/glib (contains only the patch from the bzr branch): apt-add-repository ppa:ivoks/glib ; apt-get update ; apt-get -y upgrade Start corosync: service corosync start Run the test again: lrmadmin -C ; lrmadmin -C ; lrmadmin -C ; lrmadmin -C It doesn't deadlock. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/887946 Title: Deadlocks in main loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/887946/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
