Bug ID: 50719
           Summary: The TestBot mishandles renames
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The TestBot analyses patches to determine whether they are Wine patches and
which tests are impacted and must be rerun.

But when a patch renames a test unit it still schedules a run for the renamed
test unit. For instance if apphelp:apphelp is renamed to apphelp:renamed, the
TestBot still schedules a run of apphelp:apphelp (in addition to the
apphelp:renamed one).

This means it does not keep track of Wine's current files list correctly, which
also impacts identifying whether a patch is a Wine patch or not, particularly
for patch series.

This can be tested with the following wtbsuite tests:
WTBS Check combined renaming and modifying a file (apphelp:apphelp).
[2/2] WTBS S10.2 - ...before renaming it in the next part (amstream:amstream).
[7/7] WTBS S5.7 - Check for rename+addition+removal conflicts (msi:suminfo).
