Bug ID: 21801
Summary: [IndexedDB] Cursor operations when source deleted are
not defined
Classification: Unclassified
Product: WebAppsWG
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Indexed Database API

In a version change transaction:
store = db.createObjectStore("store");
db.deleteObjectStore("store");
store.put(0, 0); // throws InvalidStateError since object is deleted
But consider:
store = db.createObjectStore("store");
store.put(0, 0);
store.openCursor().onsuccess = function(e) {
var cursor = e.target.result;
if (cursor) {
db.deleteObjectStore("store");
cursor.continue();
}
};
The behavior here does not appear to be specified. It seems to me it should
also throw InvalidStateError. This could be specified by adding to the
operation descriptions for IDBIndex continue, advance, update and delete:
"If the cursor's source or effective object store has been deleted, the
implementation MUST throw a DOMException of type InvalidStateError."
(The same would apply to operations on an index if its object store is deleted.
That also seems underspecified.)
