|Title||Multiple Perforce sections in the Bugzilla form|
|Assigned user||Nick Barnes|
|Description||A user who upgrades from one version of the P4DTI to another but omits to remove their old Bugzilla patch may find that the new Bugzilla patch applies and they get two Perforce sections in the bug form and two p4dti Bugzilla parameters.|
We tell people to remove the old patch in the readme.txt, but this is easy to miss. Removing the old patch currently requires the old patch file, and users may have deleted this before being ready to apply the new patch. In particular, Linux RPM users will remove the old RPM before installing the new RPM, and removing the old RPM will remove the old patch file.
This is less severe with Bugzilla 2.16 or later, because the patch creates a file and so reapplying the patch will fail, instead of simply complaining.
|Analysis||Could do our own patch removal by suitably marking the code which we add to Bugzilla and writing a small script to remove it. Otherwise this is a hard problem. We can't do it in the RPM scripts because they don't know where Bugzilla is installed. We could ship all the old patch files with the new release, along with a script which will identify which patch (if any) has already been applied and remove it before installing the new patch. This could work as we are unlikely to have very many versions of the patch (currently there are two).|
GDR 2001-07-17: In fact the patches change quite frequently, so this isn't as good as it looks at first sight. We could include in the patch a Perl comment that identifies the P4DTI release. This would make it a bit easier.
Need to fix upgrade instructions in the readme.txt.
