1038373 - In case of inner window reusage DisallowBFCaching may not work correctly

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[Olli Pettay [:smaug][[e-mail]]]

As far as I see some code might call DisallowBFCaching on the initial doc, and
once a new doc is loaded, it doesn't have the flag set.

But I don't actually understand the setup for the method at all.
Bug 696591 added code to nsDocumentViewer, but didn't to nsDocument::CanSavePresentation()

Kyle, do you recall what lead to the patch in bug 696591?

IndexedDB needs to evict documents from the bfcache in certain circumstances.  In Bug 696591 we had a case where the document was going into the bfcache but was not already there, so we could not evict it.
