It's not just symbol names (which were easily obtainable for the Ubuntu build), but also the stack trace. In debugging the original bug, I got to nsUrlClassifierDBServer only with a debug/unoptimized build; the optimized build + debug symbols yielded nothing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/585061 Title: Segfaults in nsUrlClassifierDBService.cpp when homedir is inaccessible -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Okay, I've been testing Namoroka 3.6.13 versus 3.6.14pre (post-dating this fix), and I'm afraid to say the results are less than conclusive. * I get crashes with 3.6.13, although not as frequently as with Ubuntu's 3.6.13; * I get crashes with 3.6.14pre, also not as frequently, though these are due to SIGBUS (seemingly stemming from Flash), which is a different failure mode from this bug; * Ubuntu 3.6.13 plus my patch is the only build that has proven uncrashable so far; * Because the Namoroka builds are optimized, there's not much I can do in the way of post-mortem to see what's going on. All of these are with the same ~/.mozilla directory, and thus the same runtime configuration. Wish I could report a before-vs.-after smoking gun, but the reality is more of a muddle. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/585061 Title: Segfaults in nsUrlClassifierDBService.cpp when homedir is inaccessible -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(In reply to comment #24) Al: I'm presuming the ideal is to reproduce a crash with 3.6.13, and observe the lack of one with 3.6.14pre. However, whichever of the two I install, the auto-update installs the new 3.6.14pre nightly---which may be affecting the behavior of the bug. How should I go about testing this?

The autoupdate shouldn't be triggered for many hours. If you download a clean 3.6.13 released build from the website and run it, it shouldn't autoupdate very soon. You can then download the current 3.6.14pre build and try it there. The other option is to use the profilemanager to set up a different profile for this but you shouldn't need to do so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/585061 Title: Segfaults in nsUrlClassifierDBService.cpp when homedir is inaccessible -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

From the context, there seems to be no real way for me, as QA, to verify this fix. I don't have the correct setup to reproduce the problem.

[Bug 585061] [NEW] [PATCH] Segfaults in nsUrlClassifierDBService.cpp when homedir is inaccessible
Public bug reported: Binary package hint: firefox This concerns firefox 3.6.3+nobinonly-0ubuntu4 in Ubuntu Lucid. I use Firefox on a system in which home directories are served from an AFS file server. When a user's Kerberos authentication expires, access to the entire home directory is cut off, and all attempts to read or write to it fail with EACCES. This occurs regularly on my workstation: I stay logged in for weeks at a time, with a more-or-less permanent instance of Firefox running, and every night after I leave work my authentication expires and Firefox sits for a few hours without any access to its configuration files under ~/.mozilla/. When I return in the morning, I renew my authentication, and my home directory becomes accessible again, but by this point Firefox has usually vanished without a trace. I debugged this problem using a local build of the Firefox deb source, and have found where the segfaults are occurring: All of them appear to be in nsUrlClassifierDBService.cpp. The code assumes in a couple of places that mConnection is non-NULL, but every time the browser crashes on me, that assumption did not hold. I am attaching a preliminary patch that, so far, has eliminated the crashes. I now find Firefox still hanging around every morning, with a number of A script has become unresponsive... dialogs that are easily cleared away. ** Affects: firefox (Ubuntu) Importance: Undecided Status: New -- [PATCH] Segfaults in nsUrlClassifierDBService.cpp when homedir is inaccessible https://bugs.launchpad.net/bugs/585061 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
