Dale,
Thank you very much for the explanations. That helps me a lot.
The way I installed tODE was definitely unorthodox, and I know it's not fair to ask you to support non-standard installations, so don't feel pressured to fix my problems here. I'd just appreciate some general guidelines.
We've got lots of infrastructure built around the old way of running GLASS apps; the stone runs from /opt/gemstone/product/seaside and we have a number of helper scripts running from there. So I didn't want to dive head-on into the tODE-managed stone world if I didn't have to, and right now I'm trying to take baby steps into it. If I could continue to run my stone and scripts from the old tree, that'd be ideal… but if that's asking for trouble, I can give up on my ideals.
To load tODE, I first ran my repo through a full upgrade from 3.2.15 to 3.3.6 (upgradeImage, upgradeSeasideImage, etc). Then, I downloaded GsDevKit_home, ran the `installServer` script, and loaded the tODE code using Metacello. Here's the script I used:
#!/bin/bash -e
#
# Run as normal user with sudo privileges
export GEMSTONE=/opt/gemstone/product
export GEMSTONE_NAME=${GEMSTONE_NAME:-seaside}
# Install tODE
export GS_HOME=/opt/gemstone/GsDevKit_home
export GS_SHARED_REPO="${GS_HOME}/shared/repos"
export GS_SHARED_REPO_TODE="filetree://${GS_SHARED_REPO}/tode/repository"
sudo -u gsadmin -E $GEMSTONE/bin/topaz -lq <<EOF
set user DataCurator gems $GEMSTONE_NAME pass redacted
login
run
GsDeployer bulkMigrate: [
Metacello new
baseline: 'FileTree';
repository: 'filetree://${GS_SHARED_REPO}/filetree/repository';
get.
Metacello new
baseline: 'Metacello';
repository: 'filetree://${GS_SHARED_REPO}/metacello-work/repository';

Metacello new

onConflict: [:ex | ex disallow];

That all went fine, and at that point I was able to connect to the stone with a tODE client on my laptop via an SSH tunnel for the NetLDI port. Here's my session config:
TDSessionDescription {
#name : 'Production',
#stoneHost : 'localhost',
#stoneName : 'seaside',
#gemHost : 'localhost',
#netLDI : '',
#netLDIPort : '50380',
#gemTask : 'gemnetobject',
#userId : 'DataCurator',
#password : 'redacted',
#osUserId : nil,
#osPassword : nil,
#dataDirectory : nil,
#backupDirectory : '/opt/gemstone/product/seaside/data/backups/',
#snapshotDirectory : '/opt/gemstone/product/seaside/data/snapshots/',
#gemstoneVersion : '3.3.6',
#gciLibraryName : nil,
#adornmentColor : nil,
#serverGitRoot : nil,
#serverTodeRoot : '/opt/gemstone/GsDevKit_home',
#authorId : nil
}
But then, as you saw, I couldn't perform certain operations that needed to talk to the GsDevKit_home file tree. Is the #serverTodeRoot spec enough, or does the stone process on the server need tODE-specific environment variables, or are there some class vars that need to be set?
I couldn't figure out how to copy a stack from the tODE debugger, but I took a screenshot (attached). If I'm reading it right, my root node doesn't have a "sys" child at all… ?

When a project is stored in a git repository it is not necessary to record the versions of the individual mcz files in the ConfigurationOf* (a very tedious process) so the "version specs" aren't necessary.

I would suggest that you create tODE scripts using `touch sh <script-name>` for your load scripts and other maintenance tasks. Ask questions on this list if you need some more pointers.
