‘guix lint’ catches that:
--8<---------------cut here---------------start------------->8---
$ guix lint -c profile-collisions python-pygenometracks
gnu/packages/bioinformatics.scm:11896:2: python-pygenometracks@3.3: propagated
inputs python-distlib@0.3.1 and python-distlib@0.3.0 collide
--8<---------------cut here---------------end--------------->8---
The Data Service should notice these new warnings, though I was unable
to find it, and
<http://data.guix.gnu.org/revision/b5ed51bdf93de46e0852fda3738690f820ada439/lint-warnings?locale=en_US.UTF-8&package_query=python-virtualenv&linter=profile-collisions&message_query=&field=linter&field=message&field=location>
doesn’t seem to have this warning.
We definitely need automated feedback before a patch can be applied.
Another thing we could do is have ‘guix lint’ check the dependents of a
package in addition to the package itself in some cases (maybe just for
‘profile-collisions’?).
Thoughts?
Ludo’.
