[Fwd: Apport]

From: James Westby <jw+debian(a)jameswestby.net&gt; To: distributions(a)lists.freedesktop.org Subject: Apport Date: Fri, 02 May 2008 21:58:23 +0100 Hi all, I just wanted to let you all know about a little package that we use in Ubuntu that may benefit other distributions. This package is called "apport". Apport is an automatic bug reporting tool. It does a number of things, the main one of which is to pop up on crashes of system programs. To do this it installs a kernel core pattern in /proc/sys/kernel/core_pattern that pipes core files to it (available since the .23 kernel I believe). This writes out a .crash file to /var/crash. The user is then notified with a notification icon and libnotify message that something has crashed. Clicking on the icon tells them what and offers to report a bug. For Ubuntu this opens a new bug in launchpad with all the information, and then opens the page in the users web browser for them to provide more details. It also hooks in to python failures somehow to provide the same service, and also has intergration with update-manager so that you can report a bug if a package installation/upgrade fails. Some people may be disturbed by the thought of the flood of bugs that would be generated. You're right, it does generate a lot of bug reports, but there are a few things that make it worthwhile. Firstly, it's only active for development releases, as it's easiest to fix the bugs then, and those users will generally be more equipped to provide the necessary information. Secondly, and this is what makes apport so great, it can detect duplicates by itself. It takes the core file, enters a chroot, and using some magic it "retraces" the bug report, using full symbol table information. This means that it can detect duplicates on it's own and mark them as such, and also that without the users having to have debugging symbols in their executable, or know what gdb is, provide full backtraces. In addition to this a package can provide an apport script that gathers information from a user's system before reporting the bugs. For instance Firefox can report all of the extensions that the user has installed. It is obviously currently quite specific to Ubuntu, however it is surely possible to make it work on other systems as well, and I'm sure Martin would be happy to merge patches that did that. You can find more details about the project at https://wiki.ubuntu.com/Apport and the code at https://launchpad.net/apport I think other distributions would do well to look at it, and even if you don't want to use it in your distribution there may be ideas that you want to take. Does anyone else already have a system like this? Are there any aspects that are covered by other tools used in your distro? Can anyone see anything that would make it even better?
