Description Dan Callaghan 2014-01-05 22:37:54 UTC
Description of problem:
python-cssmin and ycssmin both provide /usr/bin/cssmin which conflicts.

Version-Release number of selected component (if applicable):
python-cssmin-0.1.4-5.fc19.noarch

How reproducible:
always

Steps to Reproduce:
1. yum install python-cssmin ycssmin
or any other yum transaction which pulls in both of those packages.

Actual results:
Transaction Check Error:
  file /usr/bin/cssmin conflicts between attempted installs of ycssmin-1.0.1-3.fc19.noarch and python-cssmin-0.1.4-5.fc19.noarch

Expected results:
No conflict.

Additional info:
I've filed this against python-cssmin since ycssmin seems to have claimed the name first (judging by git commit dates). But considering how many "CSS minification" implementations exist right now, I would suggest that neither package should own /usr/bin/cssmin. Either way, the implicit file conflict is a bug.

Comment 1 Martin Krizek 2014-01-06 13:04:25 UTC
Thanks for filling the bug. Do you have a suggestion regarding the new name of the file?

Comment 2 Stephen Gallagher 2014-01-06 13:18:40 UTC
The problem is that there are plenty of other packages that rely on /usr/bin/cssmin being ycssmin (it's coded into their build-systems). Martin: do you know if python-cssmin takes all of the same arguments? Looking it up, python-cssmin is apparently a python port of ycssmin. If that's the case, we might be able to hack together an 'alternatives' solution here.

Seems like the ycssmin binary only reads stdin (please correct me if I am wrong) while the python-cssmin binary does the same and in addition takes -h, --help, --version, -w, --wrap arguments.

Comment 4 Dan Callaghan 2014-02-10 02:55:48 UTC
So I guess the two possibilities are to rename python-cssmin's binary to /usr/bin/python-cssmin (because ycssmin got there first) or to set up alternatives to manage /usr/bin/cssmin as a symlink.

Either way I'd appreciate a fix for this since it is breaking our builds due to the rpm file conflict.
