mod_dav, do we have a problem?

Tracking down a strange bug this morning, using Javascript code in FireFox+FireBug against Apache 2.2 and mod_dav. My test code does a PUT soon followed by a HEAD to the same URI (part of logic that tests to see if the file just created actually exists). But the HEAD command returns inconsistent results: sometimes 404, sometimes not, running the same test suite with no other changes. I did manage to see the incorrect sequence in a Wireshark trace, so I think that lets FF off the hook here.

A simple, but dubious, workaround is to put a 100ms delay in the test suite after initially creating the test fixture data; now all tests run fine, repeatedly.

I still find that FireFox can be a bit inconsistent in the time it takes to do things (garbage collection?), so some tests time out occasionally, but I can live with this.

Using: MacOS 10.5 and 10.6, Apache 2.2 (XAMPP distribution), Firefox 3.5.7, jQuery 1.4.2

Initial project planning and reporting framework

The day-to-day ADMIRAL project planning and reporting framework is being set up along the lines used for the Shuffl JISC Rapid Innovation project.  A wiki will be used for the outline project plan and sprint schedule, with separate links to individual sprint plans.  This is available at http://imageweb.zoo.ox.ac.uk/wiki/index.php/ADMIRAL_planning.  Other ongoing progress reports and commentary will be provided via this blog.

Posting tags will be used to allow aggregation of reports by interested parties, based on the tags allocated for the JISC rapid innovation projects, but using JISCMRD in place of JISCRI.
