644436 - IDBDatabase createObjectStore keyPath/autoIncrement object argument

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[Michael Putters]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: 4.0

createObjectStore normally takes three arguments, two of which are optional, as described here:

http://www.w3.org/TR/IndexedDB/#widl-IDBDatabase-createObjectStore
https://developer.mozilla.org/en/IndexedDB/IDBDatabase#createObjectStore

However, with the current implementation, the second and third arguments (keyPath and autoIncrement) have to be passed together as a single argument; this doesn't work (but should, I believe, according to the specs):

db.createObjectStore('person','id',true);

Error: uncaught exception: [Exception... "This error occurred because an operation was not allowed on an object. A retry of the same operation would fail unless the cause of the error is corrected."  code: "2" nsresult: "0x80660002 (NS_ERROR_DOM_INDEXEDDB_NON_TRANSIENT_ERR)"]

This, on the other hand, works:

db.createObjectStore('person',{keyPath:'id',autoIncrement:true});


The MDC documentation is similar to the specs while the indexedDB primer (https://developer.mozilla.org/en/IndexedDB/IndexedDB_primer) follows the implementation.

Reproducible: Always

Steps to Reproduce:
During a version update event on an IDBDatabase:
db.createObjectStore('person','id',true);
Actual Results:  
Error: uncaught exception: [Exception... "This error occurred because an operation was not allowed on an object. A retry of the same operation would fail unless the cause of the error is corrected."  code: "2" nsresult: "0x80660002 (NS_ERROR_DOM_INDEXEDDB_NON_TRANSIENT_ERR)"]

Expected Results:  
Same as db.createObjectStore('person',{keyPath:'id',autoIncrement:true});

The spec has been updated, but the updates haven't been published yet. You can look at the latest editor drafts here:
