Bug ID: 48671
           Summary: Some patches may require forcing a wineprefix update
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The TestBot updates the wineprefixes when it updates its base Wine source from
the daily Wine commits. The rest of the time it lets Wine deal with updating
the wineprefix is necessary. Furthermore Wine only updates the wineprefix when
wine.inf changes, which is the case for every Wine release.

The problem is that the wineprefix should also be updated when a patchset adds
a WINE_REGISTRY resource to an existing dll. Failing to do so may cause the
patchset tests to fail because the wineprefix is out of date.

See:

WinePrefix updates are relatively slow compared to the execution time of most
tests (about 30s vs. < 1s) so it would be good not to have to do that for every
task. An alternative would be to force a wineprefix update when a task has
failures and gets rerun as a result (pass an option to the relevant VM-side
scripts).

Note: Shared Gecko and Mono install issues should be discussed on bug 48354.
