Per the XHR spec, readystatechange event should be dispatch when we finish processing open().

As per w3c spec http://www.w3.org/TR/XMLHttpRequest/#the-send-method, section 4.7.6(8), readystatechange event needs to be called with the same state for asynchronous XMLHTTPRequest once the Send() flag is set. Looks like this is not happening with webkit. Do we need a fix for this ? 547376 2 125016 joethomas 2012-02-01 14:35:48 -0800 Created attachment 125016 Simplified test case Simplified test case showing the sequence of state when readystatechange event is fired. Webkit browsers fires readystatechange event with [1,2,3,4] (OPENED, HEADERS_RECEIVED, LOADING, DONE) whereas Firefox and IE fires with states [1,1,2,3,4]. As per spec, readystatechange event is supposed to be fired when Send() is called for asynchronous request but webkit does not do that. I will create a patch if we agree to add this. 830121 3 ap 2013-02-11 14:19:32 -0800 *** Bug 71985 has been marked as a duplicate of this bug. *** 830122 4 ap 2013-02-11 14:20:01 -0800 The duplicate has some relevant analysis. 1955191 5 annevk 2023-05-12 23:34:08 -0700 This has been addressed in the past decade. 125016 2012-02-01 14:35:48 -0800 2012-02-01 14:35:48 -0800 Simplified test case test case.html text/html 441 joethomas PGh0bWw+Cjxib2R5Pgo8c2NyaXB0PgogICAgdmFyIHhociA9IG5ldyBYTUxIdHRwUmVxdWVzdCgp OwogICAgdmFyIHJlc3VsdCA9IFtdOwogICAgeGhyLm9ucmVhZHlzdGF0ZWNoYW5nZSA9IGZ1bmN0 aW9uKCkgewogICAgICAgIHJlc3VsdC5wdXNoKHhoci5yZWFkeVN0YXRlKTsKICAgICAgICBpZiAo eGhyLnJlYWR5U3RhdGUgPT0gNCkgewogICAgICAgICAgICBhbGVydCgicmVhZHlzdGF0ZWNoYW5n ZSAtIHN0YXRlIHNlcXVlbmNlIC0gIiArcmVzdWx0KTsKICAgICAgICB9CiAgICB9CiAgICB2YXIg dXJsID0gImh0dHA6Ly9odG1sNWxhYnMuaW50ZXJvcGVyYWJpbGl0eWJyaWRnZXMuY29tL0NPUlMv Q09SU1NlcnZlci5hc3B4P1Rlc3RJRD0xMiI7CiAgICB4aHIub3BlbigiR0VUIix1cmwpOwogICAg eGhyLnNlbmQobnVsbCk7Cjwvc2NyaXB0Pgo8L2JvZHk+CjwvaHRtbD4K
