[Henrik Skupin [:whimboo][⌚️UTC+2]]

As it looks like we are trying a couple of times but then bail out because the process has still not been quit.

Comment 2

[Andrew Halberstadt [:ahal]]

Why is this marked as blocking the mozbase merge? I don't see it anywhere in the try run:
https://tbpl.mozilla.org/?tree=Try&rev=842b31a7fa8d

Comment 3

[Henrik Skupin [:whimboo][⌚️UTC+2]]

It was failing for me. If it works fine now, we should be good to remove it from the dependency list.

Comment 4

[Andrew Halberstadt [:ahal]]

Actually the new mozversion tests seem to crash on windows and then they hit this bug afterwards:
https://tbpl.mozilla.org/php/getParsedLog.php?id=34580469&tree=Try&full=1

Comment 6

[Henrik Skupin [:whimboo][⌚️UTC+2]]

The problem here is actually the following:
http://www.logilab.org/blogentry/17873

So if you request a temporary file via mkstemp() you will have to close its handle via os.close().

I think instead of mkstemp() we could create another file on our own in the tempfolder. That wouldn't hurt us at all.

Comment 7

[Henrik Skupin [:whimboo][⌚️UTC+2]]

I can fix that tomorrow morning if it's not a pressure.

Comment 8

[Henrik Skupin [:whimboo][⌚️UTC+2]]

So I'm going to fix that. Looks like the mozbase unittests never have been run on Windows during their implementation.

Landed on master:
https://github.com/mozilla/mozbase/commit/62ca95898daeb67551580f4b0b26400578f911a9

I hope that was the last blocker for the merge! :)
