[Pkg-sugar-devel] Packaging activities with mimetypes.xml files in Debian

[Martin Abente]

Hello everyone,

While packaging activities that contained a "mimetypes.xml" file like in
FotoToon [1], I noticed in the resulting package some "unexpected" files
being included under "/usr/share/mime/".

These files are created by "update-mime-database" [2] when running
bundlebuilder via "python setup.py install" for installing activities
[3,4]. In the context of packaging activities with CDBS helpers, this
happens during "install" routine [5].

The issue with these files is that they clash with the same files provided
by other packages (ie., a package for another activity with a
"mimetypes.xml" file like StopWatch [6]), and this prevents the packages
from being installed.

The problem seems to be that bundlebuilder wasn't prepared to be used like
this. I prepared a patch [7] to prevent update-mime-database execution, it
will requires to include a "--no-mime-update" argument to "./setup.py
install" and to run update-mime-database in a further step, after the
package is being installed. What do you guys think of this approach?

There is also another issue with symlinks created by bundlebuilder [8] when
installing mimetypes.xml, but not sure how it can be solved yet.

Regards,
Martin.

PS: I CC'ing Peter in case this information is useful for Fedora.
