It’s just that the new part of the test is flaky. And what seems flaky is the question of whether a type error is logged to the console. I wish I knew more about where the type error was coming from, even which JavaScript source file. 1612044 4 389031 Lawrence.j 2020-01-28 10:46:27 -0800 Created attachment 389031 Update Test Expectations 1612045 5 389031 tsavell 2020-01-28 10:48:47 -0800 Comment on attachment 389031 Update Test Expectations Clearing flags on attachment: 389031 Committed r255259: <https://trac.webkit.org/changeset/255259> 1618550 6 Lawrence.j 2020-02-13 09:58:53 -0800 I am able to reproduce this issue with r256503 using the command below. run-webkit-tests imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html --iterations 3000 --exit-after-n-failures 5 --force -f 18/3000] imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html failed unexpectedly (text diff) [24/3000] imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html failed unexpectedly (text diff) [26/3000] imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html failed unexpectedly (text diff) [27/3000] imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html failed unexpectedly (text diff) [32/3000] imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-serializable.html failed unexpectedly (text diff) Exiting early after 5 failures. 27 tests run. 22 tests ran as expected, 5 didn't (2973 didn't run): 389031 2020-01-28 10:46:27 -0800 2020-01-28 10:49:52 -0800 Update Test Expectations bug-206752-20200128104627.patch text/plain 2498 Lawrence.j U3VidmVyc2lvbiBSZXZpc2lvbjogMjU1MjU4CmRpZmYgLS1naXQgYS9MYXlvdXRUZXN0cy9DaGFu Z2VMb2cgYi9MYXlvdXRUZXN0cy9DaGFuZ2VMb2cKaW5kZXggODhiNTExMjk5ZDgxMDhhYzczOGUz MDg5YzhhODFkYzFlNGJkN2UzYS4uY2U0MzNjNjNjMzNkYTlkZTQ5MTAyMjBhMjg1NDg3N2Y3NDAz MzViMiAxMDA2NDQKLS0tIGEvTGF5b3V0VGVzdHMvQ2hhbmdlTG9nCisrKyBiL0xheW91dFRlc3Rz L0NoYW5nZUxvZwpAQCAtMSwzICsxLDEzIEBACisyMDIwLTAxLTI4ICBKYXNvbiBMYXdyZW5jZSAg PGxhd3JlbmNlLmpAYXBwbGUuY29tPgorCisgICAgICAgIFsgaU9TIHdrMiByZWxlYXNlIGFuZCBN YWMgXSBpbXBvcnRlZC93M2Mvd2ViLXBsYXRmb3JtLXRlc3RzLzJkY29udGV4dC9pbWFnZWJpdG1h cC9jcmVhdGVJbWFnZUJpdG1hcC1zZXJpYWxpemFibGUuaHRtbCBmbGFreSBmYWlsdXJlCisgICAg ICAgIGh0dHBzOi8vYnVncy53ZWJraXQub3JnL3Nob3dfYnVnLmNnaT9pZD0yMDY3NTIKKworICAg ICAgICBVbnJldmlld2VkIHRlc3QgZ2FyZGVuaW5nLgorCisgICAgICAgICogcGxhdGZvcm0vaW9z LXdrMi9UZXN0RXhwZWN0YXRpb25zOgorICAgICAgICAqIHBsYXRmb3JtL21hYy9UZXN0RXhwZWN0 YXRpb25zOgorCiAyMDIwLTAxLTI4ICBKYWNvYiBVcGhvZmYgIDxqYWNvYl91cGhvZmZAYXBwbGUu Y29tPgogCiAgICAgICAgIFsgbWFjT1MgXSBodHRwL3dwdC9yZXNvdXJjZS10aW1pbmcvcnQtcmVz b3VyY2UtZXJyb3JzLmh0bWwgaXMgZmxha3kgZmFpbGluZwpkaWZmIC0tZ2l0IGEvTGF5b3V0VGVz dHMvcGxhdGZvcm0vaW9zLXdrMi9UZXN0RXhwZWN0YXRpb25zIGIvTGF5b3V0VGVzdHMvcGxhdGZv cm0vaW9zLXdrMi9UZXN0RXhwZWN0YXRpb25zCmluZGV4IDE0NzAwNzJlZjMxNzlhODQ2ODhjZTdm YWQ4MTc0NzM0OTg4NWIwNDMuLjljYzE5NWVkNGZmMTU5Zjg5YzI4NTUzOWNjMWM1ZWVlMTUxMzMw OGYgMTAwNjQ0Ci0tLSBhL0xheW91dFRlc3RzL3BsYXRmb3JtL2lvcy13azIvVGVzdEV4cGVjdGF0 aW9ucworKysgYi9MYXlvdXRUZXN0cy9wbGF0Zm9ybS9pb3Mtd2syL1Rlc3RFeHBlY3RhdGlvbnMK QEAgLTEzNjEsNCArMTM2MSw2IEBAIHdlYmtpdC5vcmcvYi8yMDY2NzggWyBSZWxlYXNlIF0gY29t cG9zaXRpbmcvdmlkZW8vcG9zdGVyLmh0bWwgWyBQYXNzIEZhaWx1cmUgXQogCiB3ZWJraXQub3Jn L2IvMjA2Njg1IFsgRGVidWcgXSBhbmltYXRpb25zL2FuaW1hdGlvbi1kaXJlY3Rpb24tbm9ybWFs Lmh0bWwgWyBQYXNzIEZhaWx1cmUgXQogCi13ZWJraXQub3JnL2IvMjA2Njg3IGltcG9ydGVkL3cz Yy93ZWItcGxhdGZvcm0tdGVzdHMvYmVhY29uL2lkbGhhcm5lc3MuYW55Lmh0bWwgWyBQYXNzIFRp bWVvdXQgXQpcIE5vIG5ld2xpbmUgYXQgZW5kIG9mIGZpbGUKK3dlYmtpdC5vcmcvYi8yMDY2ODcg aW1wb3J0ZWQvdzNjL3dlYi1wbGF0Zm9ybS10ZXN0cy9iZWFjb24vaWRsaGFybmVzcy5hbnkuaHRt bCBbIFBhc3MgVGltZW91dCBdCisKK3dlYmtpdC5vcmcvYi8yMDY3NTIgaW1wb3J0ZWQvdzNjL3dl Yi1wbGF0Zm9ybS10ZXN0cy8yZGNvbnRleHQvaW1hZ2ViaXRtYXAvY3JlYXRlSW1hZ2VCaXRtYXAt c2VyaWFsaXphYmxlLmh0bWwgWyBQYXNzIEZhaWx1cmUgXQpcIE5vIG5ld2xpbmUgYXQgZW5kIG9m IGZpbGUKZGlmZiAtLWdpdCBhL0xheW91dFRlc3RzL3BsYXRmb3JtL21hYy9UZXN0RXhwZWN0YXRp b25zIGIvTGF5b3V0VGVzdHMvcGxhdGZvcm0vbWFjL1Rlc3RFeHBlY3RhdGlvbnMKaW5kZXggMDk3 ZTM2M2NhYTM5ZTI3ZTczMDg2MThlYWQxYzE0NjFiMjAzNjlkYS4uZGJhMDllOTEyNzU1ODZmNzY0 NDhjMDYwMzQ5ODMyMzUxZDNkMzU5NCAxMDA2NDQKLS0tIGEvTGF5b3V0VGVzdHMvcGxhdGZvcm0v bWFjL1Rlc3RFeHBlY3RhdGlvbnMKKysrIGIvTGF5b3V0VGVzdHMvcGxhdGZvcm0vbWFjL1Rlc3RF eHBlY3RhdGlvbnMKQEAgLTE5NDQsNCArMTk0NCw2IEBAIHdlYmtpdC5vcmcvYi8yMDY2ODUgYW5p bWF0aW9ucy9hbmltYXRpb24tZGlyZWN0aW9uLW5vcm1hbC5odG1sIFsgUGFzcyBGYWlsdXJlIF0K IAogd2Via2l0Lm9yZy9iLzIwNjY3MSBhbmltYXRpb25zL2FuaW1hdGlvbi1kaXJlY3Rpb24tcmV2 ZXJzZS5odG1sIFsgUGFzcyBGYWlsdXJlIF0KIAotd2Via2l0Lm9yZy9iLzIwNjcxMSBodHRwL3dw dC9yZXNvdXJjZS10aW1pbmcvcnQtcmVzb3VyY2UtZXJyb3JzLmh0bWwgWyBQYXNzIEZhaWx1cmUg XQpcIE5vIG5ld2xpbmUgYXQgZW5kIG9mIGZpbGUKK3dlYmtpdC5vcmcvYi8yMDY3MTEgaHR0cC93 cHQvcmVzb3VyY2UtdGltaW5nL3J0LXJlc291cmNlLWVycm9ycy5odG1sIFsgUGFzcyBGYWlsdXJl IF0KKword2Via2l0Lm9yZy9iLzIwNjc1MiBpbXBvcnRlZC93M2Mvd2ViLXBsYXRmb3JtLXRlc3Rz LzJkY29udGV4dC9pbWFnZWJpdG1hcC9jcmVhdGVJbWFnZUJpdG1hcC1zZXJpYWxpemFibGUuaHRt bCBbIFBhc3MgRmFpbHVyZSBdClwgTm8gbmV3bGluZSBhdCBlbmQgb2YgZmlsZQo=
