Reproducible test case
(May be a dup of <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED INVALID - IndexedDB index does not enforce uniqueness"
href="show_bug.cgi?id=60720">https://bugs.webkit.org/show_bug.cgi?id=60720</a>, 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: <a href="http://bl.ocks.org/nolanlawson/28ff2db3f3cb386c8ecb">http://bl.ocks.org/nolanlawson/28ff2db3f3cb386c8ecb</a>. 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.</pre>
