rpmbuild-order: Order RPM packages by dependencies

[ bsd3, distribution, library, program ] [ Propose Tags ]

The rpmbuild-order tool orders RPM packages by dependencies, so that they can be built in the correct order. It does this by reading RPM package spec files and then topologically sorts them according to their dependencies. The code originated from cabal-sort by Henning Thielemann. It can also output the ordered dependencies or reverse depends for one or more packages, provided all the packages are checked out in neighboring directories. This is also useful to see what packages are affected when a low-level package changes. It also have support for setting RPM options for bcond etc, which can affect dependencies. Since version 0.4 there is a library too.

rpmbuild-order

This package originally based on code from cabal-sort, sorts rpm package spec files by build order.

$ rpmbuild-order --help
$ rpmbuild-order sort mycore mylib myapp
mylib
mycore
myapp

The arguments passed can either be directories containing the package, or spec files.

If the dependency graph has cycles then an error will be output with a list of cycles and any subcycles.

Using the rpmbuild-order deps and rdeps commands the ordered dependencies and reverse dependencies of a package can be obtained from the current set of checked out package sources.

Library

As of version 0.4, a library is also provided.

There are two modules:

  • Distribution.RPM.Build.Graph provides lower level functions for generating RPM dependency graphs
  • Distribution.RPM.Build.Order provides higher level functions for sort packages in build dependency orders and output.

Please see the documentation for more details.

Notes and known problems

  1. Given packages A, B, C, where C depends on B, and B depends on A, and you call

    rpmbuild-order sort C.spec A.spec

then the output may be wrong if C does not have a direct dependency on A. Even if the order is correct, B is missing in the output and thus in this case the list of packages cannot be reliably used for a sequence of builds.

However the deps and rdeps commands take other neighbouring package directories into account.

  1. repoquery is not used to resolve meta-dependencies or files to packages. So if a package BuildRequires a file, it will not be resolved to a package. This may get addressed some day, but file dependencies seem less common for BuildRequires than Requires.

  2. rpmspec is used to parse spec files (for macro expansion etc): so missing macros packages can lead to erroneous results in some cases.
