[Zope] Confusion over INST_HOME and INSTANCE_HOME

[Tony McDonald]

Hi,
I have this which is from a stock 2.3.3 distribution under Solaris:

219 % more start
#! /bin/sh
reldir=`dirname $0`
INST_HOME=`cd $reldir; pwd`
export INST_HOME
exec /usr/local/bin/python2.1 \
     $INST_HOME/z2.py "$@"

When started up, this works fine.

Looking for INST_HOME in the src tree I get:

220 % find . -print | xargs grep INST_HOME
./inst/make_start.py:    varname='INST_HOME'
Binary file ./inst/make_start.pyc matches
./start:INST_HOME=`cd $reldir; pwd`
./start:export INST_HOME
./start:     $INST_HOME/z2.py "$@"

Doing the same for INSTANCE_HOME brings back 52 lines of matches.

I'm using the How-To at <http://www.zope.org/Members/4am/instancehome> to
have one source installation serve up loads of mini zope sites. It has
always worked well under 2.3.0, and here's a 'start' file that does work.
Thr python used is 1.52

(Zope 2.3.0)
#! /bin/sh
reldir=`dirname $0`
INSTANCE_HOME=`cd $reldir; pwd`
export INSTANCE_HOME
PYTHONHOME=/home/zope/Zope-2.3.0-src
export PYTHONHOME
exec /usr/local/bin/python $PYTHONHOME/z2.py "$@"

Whereas this start file under Zope 2.3.3,  (note: I've got both INST_HOME
and INSTANCE_HOME defined). This is also a python2.1 distribution

#! /bin/sh
reldir=`dirname $0`
INSTANCE_HOME=`cd $reldir; pwd`
INST_HOME=`cd $reldir; pwd`
export INSTANCE_HOME
export INST_HOME
PYTHONHOME=/home/zope/Zope-2.3.3-src
export PYTHONHOME
exec /usr/local/bin/python2.1  $PYTHONHOME/z2.py "$@"

Gives an import error
243 % ./start
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "/home/zope/Zope-2.3.3-src/z2.py", line 296, in ?
    import os, sys, getopt, string
ImportError: No module named os

Does anyone know what I'm doing wrong here?
