Bug 42970 – [IndexedDB] IndexedDB is missing the Transaction interface.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Andrei Popescu]

We need to implement Transaction:

http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#transaction

This interface has changed significantly due to 

http://www.w3.org/Bugs/Public/show_bug.cgi?id=9975

So we need to update the IndexedDB implementation to match the current spec first. Hence this bug depends on 42966.

use ScriptExecutionContext::Task and the CrossThreadTask stuff instead of rolling your own

put each on its own line

Hook these up to the backend interface...I actually don't think you need any FIXMEs in this file since all the work happens in the backend.

m_backend maybe?

IDBTransaction adds two new events: oncomplete and ontimeout.

Yeah, I'll check and see. If it's not working, I'll fix it in a separate patch.
