Dear Maintainer,
I've been playing with <pkg>.pyremove with dh_python3, specifically in
the genshi project. Python 3.4 added a new 2to3 fixer which rewrites
deprecated assert methods. For genshi, this means that the effects of
2to3 differ between Python 3.3 and 3.4 for some files. This
difference prevents dh_python3 from moving the files to a common
location (i.e. /usr/lib/python3/dist-packages/genshi/...).
The result of this is that the python3-genshi binary package ends up
with ./usr/lib/python3.4/dist-package paths, which lintian does not
like.
There are a couple of solutions to this: Piotr recomments an
override_dh_python3 rule to remove the pythonX.Y specific paths before
calling dh_python3. (i.e. rm -rf). I prefered to add a
python3-genshi.pyremove file, however the contents of that file must be:
/genshi/* 3.4
/Genshi.egg-info/* 3.4
to clean everything up. Here then are some suggestions for improving
the use of .pyremove.
* The dh_python3 manpage should document <pkg>.pyremove. It's
documented in dh_python2, but not dhpy3.
* Both documents should be explicit about what the paths are relative
to. In particular it's
debian/<pkg>/usr/lib/pythonX.Y/{site,dist}-packages
* In dh_python3's .pyremove file, the construction of the glob path
forgets that the directories returned by:
site_dirs = interpreter.old_sitedirs(package, version)
site_dirs.append(interpreter.sitedir(package, version))
don't end in slashes, so the contents of <pkg>.pyremove must start
with slashes (see above). I think pyremove() should check for leading
slash and add it if it's missing.
* To remove an entire directory, you should not need to add a trailing
"/*"
In summary, the python3-genshi.pyremove file should only need to
contain this to work properly:
genshi 3.4
Genshi.egg-info 3.4
Thanks!
