Prefer 'namespace which' over 'info commands', as it is faster (on local tests, around 2x) and returns a single value. Many thanks to Nathan Coulter.

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


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.

- changed the XML parsing throughout to go through a simplified API to later upgrade XML parsing in a central place.

- updated support for ns_xml 1.4, and added work-arounds for previous versions.

- added installer check for ns_xml compatibility at boot time.

first attempt at doing XML parsing using ns_xml instead of the Tcl XML stuff. Not sure yet if this is faster, although we expect that it will be. Note also that there seems to be a bug right now in ns_xml where an XML comment will screw things up, so I've added a quick prepare function that takes out comments before XML parsing... I'm not happy about that.

Moved the bootstrap and installer stuff into their own mini-package, which

let me clean up the loading of acs-tcl a bit and isolate all the bits of

APM-knowledge required in the pre-acs-tcl bootstrapping process into a single

apm file. In general, bootstrap.tcl is cleaner and easier to read.
