segfault on downgrade, repository
Last modified: 2009-04-30 08:25:20 EDT
Description of problem:
When I downgrade tog-pegasus from version tog-pegasus-2.7.0-2.el5 (shipping with
RHEL 5.2) I get a segfault in the process. Everything downgrades fine, in terms
of package installation, however i'm concerned of course by the fact there is a
segfault at all. It seems the issue stems from the repository downgrade.
I'm not sure of the implications of this, but the segfault be corrected.
If I first remove /var/lib/Pegasus/repository/, then downgrade, no segfault occurs.
strace output is attached.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.downgrade, for example, from tog-pegasus-2.7.0-2.el5 to
segfault during repo downgrade

partial tog-pegasus downgrade strace
It doesn't occur when downgrading from 2.7.x to 2.7.y or from 2.6.x to 2.6.y.
I was not able to find exact statement in the documentation, but I believe that repositories are not backward-compatible between major releases.

proposed patch for tog-pegasus 2.6.1
The issue is not present in tog-pegasus 2.7.x branch (which is shipped in RHEL5) - it's fixed by upstream.
