Summaries of packages with uninstallable Build-Depends

Tracked architectures

• kfreebsd-amd64 [last updated: Sat Jan 9 12:05:37 2010, UTC]
• kfreebsd-i386 [last updated: Sat Jan 9 12:05:59 2010, UTC]

Legend

To keep the graphs compact, labels on arrows were stripped. Hopefully, the colours will be sufficient.

• red box: source package.
• blue box: binary package.
• blue ellipse: binary1|binary2|... pointing in turn to each binary package.
• black arrow from a source package to a binary package: build-depends on.
• gray arrow from a binary package to a source package: built from.
• green arrow from a binary package to another binary package: provided by.
• purple box: binary package that got dropped from a source package.
• red box: source package that got removed.

How?

• The status is obtained from buildd.debian.org, and the reasons for the BD-Uninstallable state get extracted from there.
• The mapping from binary to source packages is done through a Sources.gz file, which means that packages that are Provided have to be special-cased (and that happens every time a binary package can't be mapped to a source package).
• Once the analysis has been performed, subgraphs are extracted, and rendered using GraphViz.

Limitations

• Versioned build-dependencies and versioned dependencies aren't represented as such (versions are ignored) at the moment (that sounds hard to deal with).
• Conflicts are not represented yet (but there was a single case for both kfreebsd-* so it didn't matter yet).
