Package: dh-python
Version: 1.20140128-1
Severity: normal
Thank you for providing dh-python with pybuild support in Jessie.
It will be nice if a "tutorial" type document with examples for a few
typical cases: distutils, cmake, autotools, ... for packages with dh
and CDBS is available as README.pybuild in /usr/share/doc/dh-python.
Manpage alone is not so easy for people to get general idea how all
these fit together.
The distutils and cmake based packages seem to be supported. But
autotool package based packages seem to require "custom" setup and I am
completely lost in manpage and struggling :-)

$ dh clean --with autoreconf,gir,python2,python3 --buildsystem=pybuild
dh_testdir -O--buildsystem=pybuild
dh_auto_clean -O--buildsystem=pybuild
E: pybuild pybuild:82: cannot detect build system, please use --system option
or set PYBUILD_SYSTEM env. variable
dh_auto_clean: pybuild --clean -i python{version} -p 2.7 --dir . returned exit
code 11
make: *** [clean] Error 11
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2

I have no idea what value should be given to PYBUILD_SYSTEM or where to
set "--system option" with what value.
I love to see this "tutorial" type document is written like what you
have posted to BTS as README.pybuild in /usr/share/doc/dh-python

You can build modules/extensions for Python 2.X *and* Python 3.X with
this debian/rules file:
#!/usr/bin/make -f
%:
dh $@ --with python2,python3 --buildsystem=pybuild
pybuild.pm will check Build-Depends* and build Python (python,
python-dev, python-dbg, python-all, python-all-dev, python-all-dbg),
Python 3 (python3, python3-dev, python3-dbg, python3-all,
python3-all-dev, python3-all-dbg) and PyPy (pypy) modules/extensions.
It can be configured via command line or CDBS-like - by exporting
PYBUILD_OPTION / PYBUILD_OPTION_interpreter /
PYBUILD_OPTION_interpreterversion env. variables in debian/rules, f.e.
* if you don't want to use debian/*.install files,
you can set DESTDIR for each interpreter (note that you can use "python2" for
all python2.X interpreters and "python3" for all python3.X ones):
export PYBUILD_DESTDIR_python2=debian/python-foo/
export PYBUILD_DESTDIR_python2-dbg=debian/python-foo-dbg/
export PYBUILD_DESTDIR_python3=debian/python3-foo/
export PYBUILD_DESTDIR_python3-dbg=debian/python3-foo-dbg/
export PYBUILD_DESTDIR_python3.1-dbg=debian/spam-pkg-with-python3.1-only/
export PYBUILD_DESTDIR_pypy=debian/pypy-foo/
* if you want to add some custom arguments to Python 3's install command:
export PYBUILD_INSTALL_ARGS_python3=--install-scripts=/usr/share/foo/
* you can disable (almost) any action via --disable / DISABLE env. var:
export PYBUILD_DISABLE=configure
export PYBUILD_DISABLE_python3.1=test
* if you want to disable Build-Depends detection:
export PYBUILD_INTERPRETERS=python{version} python{version}-dbg
export PYBUILD_VERSIONS=2.7 3.3
* if auto detection didn't detect the right build system:
export PYBUILD_SYSTEM=distutils
* if you want to add a custom command before or after each iteration:
export PYBUILD_BEFORE_BUILD=echo {version} >> '{dir}/enabled'
export PYBUILD_AFTER_INSTALL=rm -rf '{destdir}/{install_dir}/foo/tests'
Right now it supports distutils (i.e. setup.py) and custom build systems only
(I tried to add cmake one that uses dh_auto_* tools, but failed to teach cmake
which interpreter should be used).
Anyone wants to contribute more plugins? Let me know if you want some guidance
or if I can make writing plugins easier.
If your build system is not yet supported, you can use custom build system:
export PYBUILD_SYSTEM=custom
export PYBUILD_CLEAN_ARGS=rm -rf {build_dir}/python{version}/
export PYBUILD_CONFIGURE_ARGS=./configure --python={version}
export PYBUILD_BUILD_ARGS=make build --dir={build_dir} --python={version}
export PYBUILD_INSTALL_ARGS=make --destdir={destdir} --python={version}
--install-dir={install_dir}
export PYBUILD_TEST_ARGS_python2=cd {build_dir}; nosetests
export PYBUILD_TEST_ARGS_python3=cd {build_dir}; python{version} -m discover

I do not know if the above is still valid or not for cmake, since
pybuild returns as follows:
$ pybuild --list-systems
cmake CMake build system (using dh_auto_* commands)
custom use --*-args options to configure this system
distutils Distutils build system
Besides, I do not understand what is "--*-args options".

PS: I am packaging a python3 compatible upstream source (ibus). So 2to3
is not the issue . I can not take easy path by limiting this package to
python3, since this package needs to support dependencies still using
old python2 bindings.
