A bunch of things
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.
