Converting python-central based package to python-support

Step by step

cleaning up

Lenny's python-central doesn't (552595) remove old files at upgrades, so if your package is already in Lenny, you'll need to remove them in preinst maintainer script. Example:

# TODO: remove this file after releasing Squeeze
set -e
if [ "$1" = upgrade ] && dpkg --compare-versions "$2" lt 1.2-3
        pycentral pkgremove python-foo

Where 1.2-3 is the first version that uses python-support, and python-foo is the name of your package.


Sometimes pycentral pkgremove package_name is not enough. If list of files provided by your package changed in previous versions, you'll most probably have add these two lines to your preinst script:

rm -rf /usr/lib/python2.4/site-packages/foo
rm -rf /usr/lib/python2.5/site-packages/foo

Please make sure no other package is using foo namespace before you do that, though. You can check that with:

apt-file search -x '(packages|pyshared)/foo' -l


All packages that share the same namespace have to use the same helper tool so f.e. if your package provides foo/bar/baz.{py,so} files (i.e. module) - all other packages that use "foo" namespace have to use the same helper tool.
