            Bug ID: 149107
           Summary: IndexedDB does not throw ConstraintErrors for unique
                    keys
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build

Reproducible test case

(May be a dup of https://bugs.webkit.org/show_bug.cgi?id=60720, but it was marked as invalid because they didn't have a good reproducible test case.)

In WebKit Nightly 600.8.9 (as well as Safari 8.0.8), it is possible to put() two documents with the same key, even if that key is defined as a unique index.

I have a reproducible test case to demonstrate: http://bl.ocks.org/nolanlawson/28ff2db3f3cb386c8ecb. The same test is also attached to this bug.

If the bug has been successfully reproduced, then this HTML page will print "There is a bug." Note that openKeyCursor() also returns the same key twice.

This bug cannot be reproduced in either Firefox or Chrome.
