This explains why the flakiness dashboard hasn't been generating new image diffs.

...at least on Linux. Haven't tested on other platforms.

(In reply to comment #6) > (From update of attachment 69710 [details]) > Committed r69066: <http://trac.webkit.org/changeset/69066> I rolled it out. If image_diff exited with neither 0 nor 1, NRWT stopped by a ValueError.

Maybe flushing the temp files isn't enough on Windows. We might have to switch to real files that we can close(). I'll try testing on Windows. Thanks for trying to land this for me.

It turns out that on Windows, you can't open the the file created by NamedTemporaryFile. So I updated the patch to just make a temp dir and open the files using open().

also, it sure seems lately that I (at least) would benefit from try servers that ran test-webkitpy. I'll see if I can add that step to the layout bots ...
