Bug 99097 – IndexedDB: Pass type of error causing abort to IDBTransaction::onAbort

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joshua Bell]

IDBTransaction.cpp has the lovely note:

FIXME: Propagate true cause from back end (e.g. QuotaError, UnknownError, etc.)

When we fail due to a ConstraintError (e.g. when indexing) this is not passed from the back end to the front end. 

It's one of the reasons we fail this test:

This needs to be split up for landing:

LGTM

This gets us closer to being able to fix http://code.google.com/p/chromium/issues/detail?id=113118

"Internal error" makes sense because a call to this method can only be originated from the backend. Accurate?

the new lines have weird indents

Yep. The message still gets dropped on the floor when DOMError is created, though, but at least the plumbing is there.

Correct. FWIW, this is what the front end synthesizes today for all backend-triggered aborts. I left this as the default on the back end since it applies to most call sites. Places where an error is generated to fire at a request now use that error, and constraint failures from indexing get special handling.

Will fix, thanks.
