Bug 63846 – test-webkitpy doesn't work on the cygwin port

• Component: Tools / Tests
• Status: RESOLVED WORKSFORME

[Dirk Pranke]

I'm not sure if this is just the stock cygwin we use in chromium or if this also doesn't work on the version of cygwin used on the apple win bots.

[Adam Roben (:aroben)]

Doesn't work in what way? I don't see any obvious problems in <http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/14458/steps/webkitpy-test/logs/stdio>, which is running test-webkitpy under Cygwin.

Hm ... thought I added a comment to this explaining myself, but it's not there.

At least on my machine, I get lots of crashes from anything that tries to fork a command. This is stock cygwin 2.7 running on a win 7 machine.

E.g.:

Wow, that worked! 2+ years of useless rebasealls have come to and end. Thanks!
