QUICK GUIDE FOR MAINTAINERS

NOTES

dependencies

dh_pypy tries to translate Python dependencies from the requires.txt file to Debian dependencies. In many cases, this works without any additional configuration because dh_pypy comes with a build-in mapping of Python module names to Debian packages that is periodically regenerated from the Debian archive. By default, the version information in the Python dependencies is discarded. If you want dh_pypy to generate more strict dependencies (e.g. to avoid ABI problems), or if the automatic mapping does not work correctly for your package, you have to provide dh_pypy with additional rules for the translation of Python module to Debian package dependencies.

For a package pypy-foo that depends on a package pypy-bar, there are two files that may provide such rules:

Both files have the same format described in /usr/share/doc/dh-python/README.PyDist. If all you want is to generate versioned dependencies (and assuming that the pypy-bar package provides the pybar Python module), in most cases it will be sufficient to put the line pybar pypy-bar; PEP386 into either of the above files.

namespace feature

dh_pypy parses Egg's namespace_packages.txt files (in addition to --namespace command line argument(s)) and drops empty __init__.py files from binary package. pypycompile will regenerate them at install time and pypyclean will remove them at uninstall time (if they're no longer used in installed packages). It's still a good idea to provide __init__.py file in one of binary packages (even if all other packages use this feature).

private dirs

/usr/share/foo, /usr/share/games/foo, /usr/lib/foo and /usr/lib/games/foo private directories are scanned for Python files by default (where foo is binary package name). If your package ships Python files in some other directory, add another dh_pypy call in debian/rules with directory name as an argument - you can use different set of options in this call. If you need to change options for a private directory that is checked by default, invoke dh_pypy with --skip-private option and add another call with a path to this directory and new options.

debug packages

In binary packages which name ends with -dbg, all files in /usr/lib/pypy/dist-packages/ directory that have extensions different than so or h are removed by default. Use --no-dbg-cleaning option to disable this feature.

overriding supported / default PyPy versions

If you want to override system's list of supported PyPy versions or the default one (f.e. to build a package that includes symlinks for older version of PyPy or compile .py files only for given interpreter version), you can do that via DEBPYPY_SUPPORTED and/or DEBPYPY_DEFAULT env. variables.
