[PATCH v3 1/4] user32/tests: Test for parent window exposure by SetWindowPos().

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

3 TestBot errors prevented a full analysis of your patch.
If the test caused the operating system (e.g. Windows) to crash or
reboot you will probably have to modify it to avoid that.
Other issues should be reported to the TestBot administrators.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

[PATCH v3 3/4] server: Redraw composited window child on its z-order change on SetWindowPos().

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=117151

[PATCH v3 4/4] server: Don't invalidate the newly exposed child region on the parent with WS_CLIPCHILDREN.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

1 TestBot errors prevented a full analysis of your patch.
If the test caused the operating system (e.g. Windows) to crash or
reboot you will probably have to modify it to avoid that.
Other issues should be reported to the TestBot administrators.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=117152

Your paranoid android.
