Reloading substitute-data/alternate html string for unreachableURL will add an item to the back-forward-history for each reload

• Component: History
• Status: RESOLVED FIXED

[Tor Arne Vestbø]

Calling loadAlternateHTMLString on the page proxy repeatedly, or an initial loadAlternateHTMLString and then reload(), will add multiple entries for the substitute-data in the back-forward history, which does not match the behavior of a successful load and subsequent reload.

Reproducible in Safari/WebKit nightly by going to http://www.foobarbaz.com/ and clicking reload multiple times.

[Tor Arne Vestbø]

After checking Safari 5 on 10.5.8, and it also creates a new bf-item for each reload, so perhaps this is intended behavior?

The old patch was applied to an out of date version and therefore didn't apply cleanly to ToT. This is fixed now.

I think we normally mention which API test was added by filename.

I tried to figure out what was making the style bot complain about that line and couldn't figure it out. I also looked for other examples in the changelog for API tests, but couldn't find any.

I can give it another look, though.

That's why stylebot includes style guide citations!

Go to http://www.webkit.org/coding/coding-style.html and look under "Comments"

Just say something like "Added API test 'mac/BackForwardList.mm'"

Is removing this FIXME correct? We're still reseting the loadtype up front, just inside loadWithDocumentLoader() instead?

> Source/WebKit/mac/WebView/WebFrame.mm:1403
> +    _private->coreFrame->loader()->load(request, substituteData, false, _private->coreFrame->loader()->loadType());

I'm also wondering if we really need to pass in the actual load type as an argument. Isn't it more of a boolean shouldReset yes/no, where in the latter case we re-use the previous load type? It just seems a bit weird to pass in  "_private->coreFrame->loader()->loadType()", when calling load() on the same instance. If it is in fact a bool relationship, we might even be able to contain the magic of _when_ that is the case inside load(), though I'm not sure how. I assume that's what the original FIXME refers to.

The failing test explicitly says in the comments about the test that the line that's missing in the test output after this patch shouldn't be in the output in the first place. It appears the test expectation might be wrong, and the output after this patch is correct.

BackForwardList.mm doesn't appear to be included in this diff...?
