[Bug 1599754] Re: Dash restarts in the middle while refreshing or navigating
Thanks Paweł, seems like the News scope is the only one using the journal layout, and frieza is the only device where there's three columns, so that might explain why it only happens there. ** Also affects: unity8 (Ubuntu) Importance: Undecided Status: New ** Changed in: unity8 (Ubuntu) Assignee: (unassigned) => Albert Astals Cid (aacid) ** Changed in: canonical-devices-system-image Importance: Critical => High ** Changed in: canonical-devices-system-image Assignee: Alejandro J.

[Bug 1599754] Re: Dash restarts in the middle while refreshing or navigating
Attaching stacktrace of all threads with debug symbols for unity-scopes- api, unity-scopes-shell and unity8-private. I can easily reproduce the problem on frieza with News scope, by just pulling to refresh a couple of times. I wasn't able to reproduce it with Nearby scope. I've attached with gdb to the running dash and my attention was drawn by VerticalJournal::addItemToView; a breakpoint + a simple gdb script to count all calls when this problem is reproduced reveals that it's being called repeatedly in a loop - I've counted 23000+ hits and it's growing (with this bp and gdb overhead the dash runs much slower and I bet it will take a while before it gets killed).

The log exceptions are due to handling cases where the incoming result lacks art in the expected result attribute and we attempt to check other result attributes to find it.

[Bug 1599754] Re: Dash restarts in the middle while refreshing or navigating
Seems the el pais related exception is not required for the core symptom. I just simply rebooted and refreshed the news scope twice (with el pais disabled in news). I saw no exceptions in the scope- registry.log, but the hang on a long refresh followed by dash restart did occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1599754 Title: Dash restarts in the middle while refreshing or navigating To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1599754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1599754] Re: Dash restarts in the middle while refreshing or navigating
I find that the el pais scope reliably causes the log error in comment #1 in both news scope and in today scope (dashboard). Disabling el pais in both fixes it (no more exceptions). ** Also affects: canonical-scopes-project Importance: Undecided Status: New ** Changed in: canonical-scopes-project Status: New => Confirmed ** Changed in: canonical-scopes-project Importance: Undecided => Critical -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1599754 Title: Dash restarts in the middle while refreshing or navigating To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1599754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
