Package maintainers, listen up!
I have created a simple tool called rpmguard for checking differences between RPM packages. It is very similar to rpmdiff, but it prints only important changes, not all. Therefore it can be used every time a new package is built to easily see if something hasn’t went completely wrong.
So what can it do?
Currently rpmguard reports:
- new or removed Requires/Provides/Obsoletes/Conflicts
- lowering the version of Requires/Provides/Obsoletes/Conflicts
- new, removed or changed config file
- new or removed executable
- reduced number of documentation files
- changed user/group ownership
- changed file mode permissions
All the above-mentioned changed are considered important enough for the maintainer to have at least a quick look at them.
Let’s see it in action
Following packages must be installed:
- rpmlint (rpmdiff version 0.91 contains serious bugs, please use newer or from trunk – it’s important)
Then you run the tool simply by:
$ ./rpmguard.py package-1.rpm package-2.rpm
Example output (artificial, usually there is no ouput or just several lines):
added REQUIRES fooreq2 added REQUIRES rpmlib(VersionedDependencies) <= 3.0.3-1 removed REQUIRES fooreq1 lowered REQUIRES('= 0.3.4' -> '>= 0.2.7') fooreq3 added PROVIDES fooprov1 = 0.1.0 added CONFLICTS fooconf >= 1.0 removed OBSOLETES fooobs added CONFIG /etc/conf2 changed CONFIG /etc/conf1 changed MODE(0644 -> 04744) /usr/share/justfile1 reduced DOCS(2 -> 1) added EXECUTABLE /usr/bin/bin1
And now a more real-world example:
$ ./rpmguard.py kernel-2.6.31-0.86.rc3.git5.fc12.x86_64.rpm kernel-126.96.36.199-56.fc12.x86_64.rpm added REQUIRES rpmlib(PayloadIsXz) <= 5.2-1 added REQUIRES dracut >= 001-7 added REQUIRES grubby >= 7.0.4-1 removed REQUIRES mkinitrd >= 6.0.61-1
Cool, where to get it?
rpmguard is currently part of AutoQA framework, which will be used for performing various checks on Fedora packages. You can download just the rpmguard from here:
or rather download the whole AutoQA:
git clone git://git.fedorahosted.org/git/autoqa.git
and look into autoqa/tests/rpmguard.
Any feedback is really welcome. If you have any ideas:
- which other changes in RPMs should be reported
- which changes should not be reported
- how to adjust the program output
- what else to improve
- any other comments
please let me know under this blog or in the autoqa-devel mailing list. Thanks!
