The main issue is that the tool doesn't accept the paths to the images. Instead it expects via stdin the contents of both images (as byte strings), with some fields that tell it how much bytes each image uses on stdin. 1582174 1 381489 clopez 2019-10-21 17:52:38 -0700 Created attachment 381489 Patch 1582198 2 381494 clopez 2019-10-21 18:22:50 -0700 Created attachment 381494 Patch 1582277 3 381494 aperez 2019-10-22 01:02:59 -0700 Comment on attachment 381494 Patch The new Python script looks fine. I think that the failed test case of the “webkitperl” EWS is somewhat intermittent (for example here's another recent failure: https://ews-build.webkit.org/#/builders/19/builds/11760), and it should be fine to land this. 1582329 4 381494 clopez 2019-10-22 04:34:09 -0700 Comment on attachment 381494 Patch Clearing flags on attachment: 381494 Committed r251428: <https://trac.webkit.org/changeset/251428> 1582330 5 clopez 2019-10-22 04:34:13 -0700 All reviewed patches have been landed.
