Sample file database from the HTML5 database example (C:\Documents and Settings\bfulgham\Local Settings\Application Data\Apple Computer\Safari\Databases\http_webkit.org_0) after the lock out error. none

Description Brent Fulgham 2007-12-13 21:03:15 PST 
Playing with the HTML5 database implementation (http://webkit.org/misc/DatabaseExample.html) using a nightly build (sources from 10 am on 12/13/2007) under Windows XP:
1.  Start Safari (run-safari).  Open the example and create a few notes.
2.  Close Safari.  Reopen Safari.
3.  View notes, move them around, etc.
4.  Close Safari. Reopen Safari.
5.  Error message:  "Failed to open the database on disk".

Note:  I observed this after implementing changes to the threading primatives (see bug http://bugs.webkit.org/show_bug.cgi?id=16428) which may be the cause.

This is the result of the test case mentioned in the bug description.  I can't open this file to access the data.

This is due to my thread changes.  After backing them out, it seems to work properly.
