Bug 15085 – window.outerWidth/outerHeight values sometimes change when window.open() used with parameters

• Status: NEW
• Component: Tools / Tests

[David Kilzer (:ddkilzer)]

* SUMMARY
When r25206 landed [1], it caused random failures in the http/tests/security/cross-frame-access-put.html test with different values for window.outerWidth and window.outerHeight [2].  This was fixed in r25250 [2], but it was not clear why removing the window.open() parameters fixed the issue.

[3] http://trac.webkit.org/projects/webkit/changeset/25250

* STEPS TO REPRODUCE
1. Back out r25250.
2. Run two tests until the second one fails:
./WebKitTools/Scripts run-webkit-tests http/tests/navigation/target-frame-from-window.html http/tests/security/cross-frame-access-put.html

* RESULTS
About half of the time, the cross-frame-access-put.html test will fail with this diff:

-ALERT: PASS: window.outerHeight should be '0' and is.
-ALERT: PASS: window.outerWidth should be '0' and is.
+ALERT: PASS: window.outerHeight should be '-100' and is.
+ALERT: PASS: window.outerWidth should be '-500' and is.

* REGRESSION
Unknown.  Only noticed after r25206 was committed, and was fixed with r25250.
