Bug 76493 – IndexedDB: Implement create-intermediate-objects semantics when injecting values via keyPaths

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joshua Bell]

See thread:

http://lists.w3.org/Archives/Public/public-webapps/2012JanMar/0141.html

and W3C bug:

https://www.w3.org/Bugs/Public/show_bug.cgi?id=15434

Currently, when following the spec to "set the property in value pointed to by store's key path to the new value for key", WebKit does nothing if intermediate values along the keyPath can't be set, e.g.:

var record = {foo: 1};
hypotheticalSetValueViaKeyPathFunction(record, "bar.baz", "newvalue");

WebKit currently doesn't modify record in that case. The spec is being updated so that record would have the new value:

record := {foo: 1, bar: { baz: "newvalue" } }

tony@, can you r?

Name suggestions for what I've called "ensure" are appreciated.

ensure seems fine.  Maybe "validate" or "verify" as well.
