The output of the tool is an HTML report like this [2]. Usage is simple: pkgdiff -old OLD.deb -new NEW.debdebdiff?
Yes, it's like the debdiff, but also checks for changes in the content of all files in the package, divides files into specific groups based on their type, generates HTML report and supports more formats of packages (rpm, tgz, txz, etc.). The analysis of changes will be implemented in future versions.
[1] http://pkgdiff.github.com/pkgdiff/ [2] http://pkgdiff.github.com/pkgdiff/pkgdiff_reports/libqb/0.4.1_to_0.8.1/compat_report.htmlHow does it decide whether the packages are compatible?
It's just a prototype of the tool. The analysis of changes has not been implemented yet. Only classifying and visualising of changes in files and package dependencies is done. So, any changes in files or dependencies cause incompatible verdict in the report (i.e. probably breaking dependent packages).
The further development will be focused on implementing detailed checkers for each file format. For example, the ABI Compliance Checker tool will be used to analyse shared libraries and header files in the package.
