Bug 48513 – [Chromium] History related tests REGRESSED after r70723

• Component: History
• Status: RESOLVED FIXED

[Mikhail Naganov]

A number of tests (see below) fail on Chromium, having the same problem: instead of reporting "http://127.0.0.1:8000/history" in Back Forward List, they report "chrome-back-forward://go/0"

E.g. for http/tests/history/redirect-301, expected is:


============== Back Forward List ==============
        http://127.0.0.1:8000/history/redirect-301.html  **nav target**
curr->  http://127.0.0.1:8000/history/resources/redirect-target.html#2  **nav target**
===============================================


Actual is:


============== Back Forward List ==============
        http://127.0.0.1:8000/history/redirect-301.html  **nav target**
curr->  chrome-back-forward://go/0
===============================================


I searched for "chrome-back-forward", and it originates from WebKit/chromium/src/BackForwardListClientImpl.cpp, having a FIXME. Probably, it's time to do it.

I’ll try to find some time to look at this today, but if someone else can fix it before I get to it, that would be great. I have limited experience with Chrome’s back/forward implementation.

[Mihai Parparita]

I'll take a stab at this.

[Darin Adler]

On guess is that this has something to do with the backItem, currentItem, and forwardItem functions. Perhaps itemAtIndex doesn’t give the same result or there was some side effect from the old version of the functions.

Very little else changed in WebCore.

Yes, BackForwardListChromium has a custom implementation of currentItem(). Either changing it back to virtual in BackForwardList.h or making itemAtIndex(0) in the Chromium version be the same as currentItem should fix things.

That’s what we should do. In the future we probably don’t want a separate currentItem function. Unless we get rid of itemAtIndex altogether, we want to make sure that itemAtIndex(0) works properly.

Makes sense. Uploaded patch does that.
