Re: [Bug 11375] New: [IndexedDB] Error codes need to be assigned new numbers

I was confused re not overlapping with other exception codes.  As long as we
don't have overlap within this particular exception type, we're OK.

I noticed that QUOTA_ERR is commented out.  I can't remember when or why and
the blame history is a bit mangled.  Does anyone else?  In Chromium we
currently use UNKNOWN_ERR for whenever we have issues writing stuff to disk.
 We could probably tease quota related issues out into their own error.
 And/or we should probably create or find a good existing error for such
uses.

Speaking of which, we use UNKNOWN_ERR for a bunch of other
internal consistency issues.  Is this OK by everyone, should we use another,
or should we create a new one?  (Ideally these issues will be few and far
between as we make things more robust.)

We also use UNKNOWN_ERR for when things are not yet implemented.  Any
concerns?

What error code should we use for IDBCursor.update/delete when the cursor is
not currently on an item (or that item has been deleted)?

TRANSIENT_ERR doesn't seem to be used anywhere in the spec.  Should it be
removed?

As for the numbering: does anyone object to me just starting from 1 and
going sequentially?  I.e. does anyone have a problem with them all getting
new numbers, or should I keep the numbers the same when possible.  (i.e.
only UNKNOWN_ERR, RECOVERABLE_ERR, TRANSIENT_ERR, TIMEOUT_ERR, DEADLOCK_ERR
would change number, but the ordering of those on the page would change.)

I intend to tackle this early next week unless there are major areas of
contention.
