And I thought perhaps I'd been annoying people too much and people had
redirected my posts to /dev/null :-)
I've not look in my mail till now, and there seems to be a plethora of
people posting solutions. I feel we are starting to approach the point of
too many cooks, and am tempted to back out rather than add more confusion.
Now that Neil is back, I see he has posted that he has some scripts ready
for this, and I'd trust that his are worth using. However, if you are still
interested, I have started down the path of experimenting with various
preinst and prerm scripts based on the 2.1 packages in unstable. Even if you
don't want to use them, they might provide ideas.
The files attached are;
pythonX.Y-base.postinst
pythonX.Y-base.prerm
postinst and prerm scripts should be usable for all pythonX.Y-base packages,
just redefine VERSION at the start.
update-python
A script to be called by version independant python packages in their
postinst and postrm scripts. This should probably be provided by the
python-base package.
Note that these scripts are _untested_. They assume the following directory
structure;
/usr/lib/pythonX.Y/ pythonX.Y installation directory
/usr/lib/python/ version independant packages installation directory
/usr/local/lib/python/X.Y local version dependant modules
/usr/local/lib/python/ local version independant modules
They create and compile symlinks into the relevant */python/ directory in
*/pythonX.Y/ directories. They also clean up dangling symlinks and any
associated *.pyc or *.pyo files.
They have some minor deficiencies, the biggest being any directorys created
in */pythonX.Y/ directories during symlink creation will not be cleaned up.
This is a bit tricky, as it is hard to determine when directories are
created for symlinks, and when they are created by some other package.
Note that these scripts are very simple and would be easy to modify. In
particular, I'm not familiar with any /usr/local/python conventions, so they
probably need adjusting there.
