[PATCH 0/1] MR3862: user32/tests: Ignore other messages in test_broadcast.

[Esme Povirk (＠madewokherd)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=54194

If the SendMessageTimeout call takes a long time, we can get other
messages which also set the observed wparam value. Apparently,
this is especially likely on Windows 7.

This also removes the (wParam == 0xbaadbeef) check which may have
been intended to serve the same goal but doesn't work because the
observed wParam value is still assigned.

[PATCH 1/1] user32/tests: Ignore other messages in test_broadcast.

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.

2 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 full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=151991

Your paranoid android.
