Last modified: 2015-06-29 08:45:02 EDT
Description of problem: Bug 1024076 is considered by abrt to be bug 1021507. See bug 1021507 comment 20. Version-Release number of selected component (if applicable): abrt-2.1.8-1.fc20 How reproducible: Always
Thank you for the report. This is a consequence of machine based comparison of backtraces. While searching for duplicate reports, the bugzilla reporter tries to find a bug having a value of abrt_hash from Whiteboard equal to a value of duphash element from the reported exception. In case of anaconda bugs the duphash is generated by python-meh [1] and it seems that python-meh's duphash generator does not produce sufficiently unique hashes. The algorithm hashes only function, file and text [2] but this is not enough for exceptions thrown by blivet. It seems that all exceptions which are generated in blivets's command handler are caught, wrapped and re-thrown as an instance of DeviceCreateError exception [3]. The simplest solution is to add reported exception's text to the hashed bytes but this will generate different hashes for same exceptions throw in different localizations. IMO, there are only two reliable solutions: 1. extend Python's Exception model with some mechanism providing an unique identifier for all exception instances 2. show users possible duplicate reports and let them decide which one is real duplicate I prefer the second solution since the first is Utopia. Or we can preserve the current state where package maintainer asks reporters to open a separate bug. Any thoughts on that? 1: https://git.fedorahosted.org/cgit/python-meh.git/tree/meh/handler.py#n258 2: https://git.fedorahosted.org/cgit/python-meh.git/tree/meh/dump.py#n469 3: https://git.fedorahosted.org/cgit/blivet.git/tree/blivet/devices.py#n1559
CCing David Lehman because of bug 1021507 comment 20. David, would it be possible to not wrap all exceptions in DeviceCreateError type?
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
