But the first time a render is performed WKCACFViewGetLastCommitTime is zero. We should check for this case and correct it so webkit doesn't think animations started in the distant past. 364013 1 85056 cmarrin 2011-03-08 10:04:10 -0800 Created attachment 85056 Patch 364024 2 cmarrin 2011-03-08 10:30:14 -0800 Landed in http://trac.webkit.org/changeset/80570 85056 2011-03-08 10:04:10 -0800 2011-03-08 10:09:07 -0800 Patch bug-55947-20110308100354.patch text/plain 1607 cmarrin SW5kZXg6IFNvdXJjZS9XZWJDb3JlL0NoYW5nZUxvZwo9PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09Ci0tLSBTb3VyY2UvV2Vi Q29yZS9DaGFuZ2VMb2cJKHJldmlzaW9uIDgwNTY2KQorKysgU291cmNlL1dlYkNvcmUvQ2hhbmdl TG9nCSh3b3JraW5nIGNvcHkpCkBAIC0xLDMgKzEsMTcgQEAKKzIwMTEtMDMtMDggIENocmlzIE1h cnJpbiAgPGNtYXJyaW5AYXBwbGUuY29tPgorCisgICAgICAgIFJldmlld2VkIGJ5IE5PQk9EWSAo T09QUyEpLgorCisgICAgICAgIFRoZSBmaXJzdCB0aW1lIGFuaW1hdGlvbnMgYXJlIGNvbW1pdHRl ZCB0aGV5IGhhdmUgYSBiYWQgc3RhcnQgdGltZQorICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0 Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9NTU5NDcKKworICAgICAgICBEbyBhIGNoZWNrIGZvciBhIHJl dHVybmVkIGxhc3RDb21taXRUaW1lIG9mIDw9MCBhbmQgcmVwbGFjZSBpdAorICAgICAgICB3aXRo IHRoZSBtZWRpYVRpbWUuCisKKworICAgICAgICAqIHBsYXRmb3JtL2dyYXBoaWNzL2NhL3dpbi9D QUNGTGF5ZXJUcmVlSG9zdC5jcHA6CisgICAgICAgIChXZWJDb3JlOjpDQUNGTGF5ZXJUcmVlSG9z dDo6bm90aWZ5QW5pbWF0aW9uc1N0YXJ0ZWQpOgorCiAyMDExLTAzLTA4ICBKYW1lcyBLb3ppYW5z a2kgIDxrb3pAY2hyb21pdW0ub3JnPgogCiAgICAgICAgIFJldmlld2VkIGJ5IERhdmlkIExldmlu LgpJbmRleDogU291cmNlL1dlYkNvcmUvcGxhdGZvcm0vZ3JhcGhpY3MvY2Evd2luL0NBQ0ZMYXll clRyZWVIb3N0LmNwcAo9PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09Ci0tLSBTb3VyY2UvV2ViQ29yZS9wbGF0Zm9ybS9ncmFw aGljcy9jYS93aW4vQ0FDRkxheWVyVHJlZUhvc3QuY3BwCShyZXZpc2lvbiA4MDUwNCkKKysrIFNv dXJjZS9XZWJDb3JlL3BsYXRmb3JtL2dyYXBoaWNzL2NhL3dpbi9DQUNGTGF5ZXJUcmVlSG9zdC5j cHAJKHdvcmtpbmcgY29weSkKQEAgLTMwOCw3ICszMDgsMTEgQEAgdm9pZCBDQUNGTGF5ZXJUcmVl SG9zdDo6Y29udGV4dERpZENoYW5nZQogdm9pZCBDQUNGTGF5ZXJUcmVlSG9zdDo6bm90aWZ5QW5p bWF0aW9uc1N0YXJ0ZWQoKQogewogICAgIGRvdWJsZSBjdXJyZW50VGltZSA9IFdURjo6Y3VycmVu dFRpbWUoKTsKLSAgICBkb3VibGUgdGltZSA9IGN1cnJlbnRUaW1lICsgbGFzdENvbW1pdFRpbWUo KSAtIENBQ3VycmVudE1lZGlhVGltZSgpOworICAgIGRvdWJsZSBjb21taXRUaW1lID0gbGFzdENv bW1pdFRpbWUoKTsKKyAgICBkb3VibGUgbWVkaWFUaW1lID0gQ0FDdXJyZW50TWVkaWFUaW1lKCk7 CisgICAgaWYgKGNvbW1pdFRpbWUgPD0gMCkKKyAgICAgICAgY29tbWl0VGltZSA9IG1lZGlhVGlt ZTsKKyAgICBkb3VibGUgdGltZSA9IGN1cnJlbnRUaW1lICsgY29tbWl0VGltZSAtIG1lZGlhVGlt ZTsKICAgICBBU1NFUlQodGltZSA8PSBjdXJyZW50VGltZSk7CiAKICAgICBIYXNoU2V0PFJlZlB0 cjxQbGF0Zm9ybUNBTGF5ZXI+ID46Oml0ZXJhdG9yIGVuZCA9IG1fcGVuZGluZ0FuaW1hdGVkTGF5 ZXJzLmVuZCgpOwo=
