OpenACS

1. AOLserver 4.0's nsxml appears to expose a gcc bug which causes the

  backwards-compatible "getattr" command to fail.  I dug around nsxml

  and it does appear to be a gcc bug.  I changed to the proper nsxml v2

  syntax.

2. In the course of exploring #1 above, I realized that the calls to

  dom:: Tcl XML package commands were still being executed despite

  being commented out.  Typical Tcl misunderstanding on someone's part.

  Net effect: we were parsing all APM .info files twice, once in Tcl

  and once in ns_xml!   Yuk!

3. Fixed a minor notifications bug - you couldn't delete a notification

  request if any unsent notifications were pending, causing the homework

  package to bomb if you deleted an uploaded homework file and the prof

  hadn't yet received their notification.

4. Fixed an obscure corner case in my permissions denormalization code.
