python-mkdebian - Generate a suitable Debian source package for a standard distutils application
SYNOPSIS
python-mkdebian [options]
DESCRIPTION
This script generates a reasonably Debian Policy compliant Debian source package for a Python application that uses distutils properly. It
assumes that there are no public Python modules, and generates just a single application binary package.
Information is taken from setup.py's generated .egg-info file: author, project name, description, version, upstream source, license, and
required and provided Python modules (which are translated to Debian python library package names, and automatically added as package
dependencies).
It generates a simple cdbs/python-support rules file.
python-mkdebian was designed to be used with the DistUtilsExtra.auto module, which calculates required Python dependencies automatically.
However, it makes no explicit assumptions about DistUtilsExtra, so if setup.py has complete information it will work with any distutils
setup.
OPTIONS --force-control=FORCE_CONTROL
Force control file behaviour. Can be one of "none" (keep unchanged), "deps" (only update dependencies), or "full" (recreate whole
file). By default only dependencies will be updated ("deps").
--force-copyright
Force whole copyright file to be recreated. By default it will not touch an already existing copyright file, so that you can custom-
ize them.
--force-rules
Force whole rules file to be recreated. By default it will not touch an already existing rules file, so that you can customize them.
--changelog=CHANGELOG
Add changelog entry to debian/changelog (can be specified multiple times)
--dependency=PACKAGENAME
Add additional debian package dependency (can be specified multiple times)
--prefix=PREFIX
Ask for installing all your modules in the dedicated PREFIX (default is /usr)
--version
Show program's version number and exit
-h, --help
Show this help message and exit

DH_PYTHON2() DH_PYTHON2()
NAME
dh_python2 - calculates Python dependencies, adds maintainer scripts to byte compile files, etc.
SYNOPSIS
dh_python2 -p PACKAGE [-V [X.Y][-][A.B]] DIR_OR_FILE [-X REGEXPR]
DESCRIPTION
QUICK GUIDE FOR MAINTAINERS
o if necessary, describe supported Python versions via X-Python-Version field in debian/control,
o build-depend on python or python-all or python-all-dev (>= 2.6.6-3~),
o build module/application using its standard build system, remember to build extensions for all supported Python versions (loop over
pyversions -vr),
o install files to the standard locations, add --install-layout=deb to setup.py's install command if your package is using distutils,
o add python2 to dh's --with option, or:
o include /usr/share/cdbs/1/class/python-distutils.mk in debian/rules and depend on cdbs (>= 0.4.90), or:
o call dh_python2 in the binary-* target,
o add ${python:Depends} to Depends
NOTES
In order to support more than one Python version in the same binary package, dh_python2 (unlike dh_pycentral and dh_pysupport) creates sym-
links to all supported Python versions at build time. It means binNMU (or sourceful upload in case of architecture independent packages) is
required once a list of supported Python version is changed. It's faster and more robust than its competitors, though.
dependencies
dh_python2 tries to translate Python dependencies from requires.txt file to Debian dependencies. Use debian/pydist-overrides or --no-guess-
ing-deps option to override it if the guess is incorrect. If you want dh_python2 to generate more strict dependencies (f.e. to avoid ABI
problems) create debian/python-foo.pydist file. See /usr/share/doc/python-doc/README.PyDist (provided by python-doc package) for more
information. If the pydist file contains PEP386 flag or set of (uscan like) rules, dh_python2 will make the depedency versioned (version
requirements are ignored by default).
namespace feature
dh_python2 parses Egg's namespace_packages.txt files (in addition to --namespace command line argument(s)) and drops empty __init__.py
files from binary package. pycompile will regenerate them at install time and pyclean 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 pack-
ages 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 is shipping Python files in some other directory, add another dh_python2 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 (f.e. a
list of supported Python versions) for a private directory that is checked by default, invoke dh_python2 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/python2.X/{site,dist}-packages/ directory that have extensions differ-
ent than so or h are removed by default. Use --no-dbg-cleaning option to disable this feature.
pyinstall files
Files listed in debian/pkg.pyinstall file will be installed as public modules for all requested Python versions (dh_install doesn't know
about python's site- vs. dist-packages issue).
Syntax: path/to/file [VERSION_RANGE] [NAMESPACE]
debian directory is automatically removed from the path, so you can place your files in debian/ directory and install them from this loca-
tion (if you want to install them in "debian" namespace, set NAMESPACE to debian). If NAMESPACE is set, all listed files will be installed
in .../dist-packages/NAMESPACE/ directory.
Examples:
o foo.py installs .../dist-packages/foo.py for all supported Python versions
o foo/bar.py 2.6- installs .../dist-packages/foo/bar.py for versions >= 2.6
o foo/bar.py spam installs .../dist-packages/spam/bar.py
o debian/*.py spam.egg 2.5 installs .../python2.5/site-packages/spam/egg/*.py files
pyremove files
If you want to remove some files installed by build system (from all supported Python versions or only from a subset of these versions),
add them to debian/pkg.pyremove file.
Examples:
o *.pth removes .pth files from .../dist-packages/
o bar/baz.py 2.5 removes .../python2.5/site-packages/bar/baz.py
overriding supported / default Python versions
If you want to override system's list of supported Python versions or the default one (f.e. to build a package that includes symlinks for
older version of Python or compile .py files only for given interpreter version), you can do that via DEBPYTHON_SUPPORTED and/or
DEBPYTHON_DEFAULT env. variables.
Example: 2.5,2.7 limits the list of supported Python versions to Python 2.5 and Python 2.7.
