Summary:	It is possible for LocalStorage to not be persistent

Description Jeremy Orlow 2009-05-20 14:23:31 PDT

LocalStorage is not database backed if page->settings()->localStorageDatabasePath() returns "".  Instead, the code should return an immutable LocalStorage (like during private browsing) rather than returning a mutable (but not database backed) version.

This is described in more detail in this email thread: https://lists.webkit.org/pipermail/webkit-dev/2009-May/007790.html

I'm happy to take this on and should be able to get to it in the next couple weeks.

FYI: I'm still planning on fixing this once I get a couple of my refactoring changes (https://bugs.webkit.org/show_bug.cgi?id=25376) in.

Any update on this ?

Any update on this? It is causing localStorage to not persist between application launches for Mac WebKit1 WebView. The only way to persist localStorage between application launches is using a private API and setting localStorageDatabasePath. This is a commonly used HTML5 feature that is broken.

Which, on Mac, is a thing you can do.

If one were writing a Mac App Store app they'd need it to be API, but we have received zero such requests at Apple.
