Bug 94972 – IndexedDB: Remove IDBDatabase.setVersion API

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joshua Bell]

The IDBDatabase.setVersion() API is from an older version of the spec, and maintained for compatibility until sites using the Chromium implementation of IndexedDB have had a chance to update. The new IDBFactory.open(name, version) / "upgradeneeded" event model is the new way to version databases.

Once a grace period has passed, we should remove it.

This patch leaves some setVersion artifacts in IDBDatabaseBackendImpl, that class is pretty fragile. There are also some remnants in the webkit api that can't be taken out until chromium code is updated.

Why keep this?

And these? I don't see anything remaining that creates them.

Looks like this patch was based on another (leading to two changelog entries and the extra diff below). Rebase please?

> LayoutTests/storage/indexeddb/removed-expected.txt:9
> +PASS 'setVersion' in IDBDatabase.prototype is false

FYI this will need rebasing as nearby lines have changed.

lgtm, w00t! (looks like it will need another rebase on top of r135856 though)
