14:19:03 -0700 <rdar://problem/4614228> 48819 3 darin 2006-07-08 09:14:29 -0700 The bug is in HTMLInputElement::defaultEventHandler. The call to doTextFieldCommandFromEvent assumes that keyEvent will return a non-0 value. But that's not true when the event is created in JavaScript -- in that case there is no platform event. Later you crash inside because the passed event is 0. A check for 0 will eliminate the crash. That leaves us with a separate issue -- keyboard equivalents for editing commands won't work for synthesized events. 49887 4 dacarson 2006-07-14 20:03:46 -0700 KeyboardEvents that are being tested here is defined here: http://www.w3.org/TR/DOM-Level-3-Events/events.html#Events-KeyboardEvent The test case is testing "KeyPress" as the key event type. According to the spec, possible keyboard event types are: keydown and keyup. I am not sure what a KeyPress does. 49900 5 ggaren 2006-07-14 23:44:51 -0700 Keypress is an HTML event that's not mentioned in the DOM spec. I doubt it matters which keyboard event you send. 49927 6 dacarson 2006-07-15 06:57:25 -0700 (In reply to comment #5) > Keypress is an HTML event that's not mentioned in the DOM spec. I doubt it > matters which keyboard event you send. > If I send a keydown for keypress, there won't be a corresponding keyup. Don't know if this is going to be a problem. I am also very confused why there are two copies of the key event data, one copy is stored in the PlatformKeyboardEvent and another copy is stored in the actual KeyboardEvent DOM class. IMHO I think that the PlatformKeyboardEvent should only be used to parse the data and populate the values in KeyboardEvent, and hold a copy of the original platform key event in case it is needed. However, it seems that the the KeyboardEvent data is not used, it is the PlatformKeyboardEvent that seems to be used. 49964 7 darin 2006-07-15 13:18:04 -0700 Committed revision 15454. 9217 2006-07-05 13:54:37 -0700 2006-07-05 13:54:37 -0700 reduction scratch-tab.html text/html 1308 ggaren PGh0bWw+CjxoZWFkPgo8c2NyaXB0PgpmdW5jdGlvbiBwcmludChtZXNzYWdlLCBjb2xvcikgCnsK ICAgIHZhciBwYXJhZ3JhcGggPSBkb2N1bWVudC5jcmVhdGVFbGVtZW50KCJkaXYiKTsKICAgIHBh cmFncmFwaC5hcHBlbmRDaGlsZChkb2N1bWVudC5jcmVhdGVUZXh0Tm9kZShtZXNzYWdlKSk7CiAg ICBwYXJhZ3JhcGguc3R5bGUuZm9udEZhbWlseSA9ICJtb25vc3BhY2UiOwogICAgaWYgKGNvbG9y KQogICAgICAgIHBhcmFncmFwaC5zdHlsZS5jb2xvciA9IGNvbG9yOwogICAgZG9jdW1lbnQuZ2V0 RWxlbWVudEJ5SWQoImNvbnNvbGUiKS5hcHBlbmRDaGlsZChwYXJhZ3JhcGgpOwp9CgpmdW5jdGlv biB3cml0ZShzKQp7CiAgICBkb2N1bWVudC5nZXRFbGVtZW50QnlJZCgncHJlJykuYXBwZW5kQ2hp bGQoZG9jdW1lbnQuY3JlYXRlVGV4dE5vZGUocykpOwp9CgpmdW5jdGlvbiBzaG91bGRCZShhLCBi KQp7CiAgICB2YXIgZXZhbEE7CiAgICB0cnkgewogICAgICAgIGV2YWxBID0gZXZhbChhKTsKICAg IH0gY2F0Y2goZSkgewogICAgICAgIGV2YWxBID0gZTsKICAgIH0KICAgIAogICAgaWYgKGV2YWxB ID09IGIpCiAgICAgICAgcHJpbnQoIlBBU1M6ICIgKyBhICsgIiBzaG91bGQgYmUgIiArIGIgKyAi IGFuZCBpcy4iLCAiZ3JlZW4iKTsKICAgIGVsc2UKICAgICAgICBwcmludCgiRkFJTDogIiArIGEg KyAiIHNob3VsZCBiZSAiICsgYiArICIgYnV0IGluc3RlYWQgaXMgIiArIGV2YWxBICsgIi4iLCAi cmVkIik7Cn0KCmZ1bmN0aW9uIHRlc3QoKSAKewogICAgZG9jdW1lbnQuZ2V0RWxlbWVudHNCeVRh Z05hbWUoJ2lucHV0JylbMF0uZm9jdXMoKTsKICAgIGlmICh3aW5kb3cubGF5b3V0VGVzdENvbnRy b2xsZXIpCiAgICAgICAgbGF5b3V0VGVzdENvbnRyb2xsZXIuZHVtcEFzVGV4dCgpOwogICAgICAg IAogICAgdmFyIGV2ZW50ID0gZG9jdW1lbnQuY3JlYXRlRXZlbnQoIktleWJvYXJkRXZlbnRzIik7 CiAgICBldmVudC5pbml0S2V5Ym9hcmRFdmVudCgia2V5cHJlc3MiLCB0cnVlLCB0cnVlLCBkb2N1 bWVudC5kZWZhdWx0VmlldywgIlUrMDAwOSIsIDAsICIiKTsKICAgIHByaW50KGV2ZW50KTsKICAg IGRvY3VtZW50LmdldEVsZW1lbnRzQnlUYWdOYW1lKCdpbnB1dCcpWzBdLmRpc3BhdGNoRXZlbnQo ZXZlbnQpOwp9Cjwvc2NyaXB0Pgo8L2hlYWQ+Cgo8Ym9keSBvbmxvYWQ9InRlc3QoKTsiPgo8cD5E ZXNjcmlwdGlvbjwvcD4KPGhyPgo8aW5wdXQgdHlwZT0idGV4dCI+PC9pbnB1dD4KPGRpdiBpZD0n Y29uc29sZSc+PC9kaXY+CjxwcmUgaWQ9J3ByZSc+PC9wcmU+Cgo8L2JvZHk+CjwvaHRtbD4K
