Bug 127683 – [WK2] http/tests/navigation/new-window-redirect-history.html crashes

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

http/tests/navigation/new-window-redirect-history.html crashes on WK2 platforms. It is 
skipped by the generic TestExpectations file with "Unexplained back/forward list failures"

[Csaba Osztrogonác]

I added the proper entry to the wk2/TestExpectations file with bug number.

run-webkit-tests -2 --no-retry http/tests/navigation/new-window-redirect-history.html

This crash happens in WebKitTestRunner code. I don't know if it's a WebKitTestRunner bug, or an API that misbehaves, and makes WebKitTestRunner crash.

[Alexey Proskuryakov]

Changed expectation from Crash to Skip in <http://trac.webkit.org/r169764>. Generating more crash logs only makes other tests more flaky without providing useful information about this test.

[Fujii Hironori]

m_previousTestBackForwardListItem was null for the new window.
m_previousTestBackForwardListItem is initialized only for the main window in InjectedBundlePage::prepare.
This code has been added in Bug 42322.

[Fujii Hironori]

I think we have two choices of solutions:

1. Do null-check of m_previousTestBackForwardListItem
2. Remove m_previousTestBackForwardListItem.
   Call WKBundleBackForwardListClear in InjectedBundlePage::prepare.
   Rebaseline all expected.txt files.
