Hi all.

 

This is Jiyeon Kim recently joined webkit-dev mailing list.

 

Welcome - I'm somewhat new here myself, but I am working on IndexedDB support in WebKit..

 

 

I’ve got two questions on IndexedDB.

First, I wonder, while Web storage and Web SQL have tracker, why Indexed DB doesn’t have tracker.

 

What do you mean by "tracker" ?

ð  Thank you for your reply.

 

Second, if you look at IDBFactory::open() method in IDBFactory.cpp file,

the fifth argument of m_backend->open(name, request.get(), context->securityOrigin(), frame, String()); is not about path information but a string (i.e., document->page()->group().groupSettings()->indexedDBDatabasePath();).

I also wonder why it is a string rather than a path.

The m_backend is an interface to the actual database implementation - that tends to deal with stuff at a slightly lower level (i.e. actual paths on disk, etc) - are you looking for a url path? All the IDB's for a security origin are accessable to each other, and not connected to the rest of the URL (i.e.  <http://foo.com/abc> http://foo.com/abc has the same security origin as  <http://foo.com/xyz> http://foo.com/xyz so they have access to the same set of IDB files, so indexedDBDatabasePath() is the same)

Thanks for your time to look into my questions.

Best regards,
