[Build-common-hackers] Bug#373997: python-distutils.mk: ignores information about minor supported python version

[Gustavo Noronha Silva]

Package: cdbs
Version: 0.4.41
Severity: important

Hello,

The current python-distutils.mk does this:

    # Calculate cdbs_python_build_versions
    cdbs_python_module_arch = $(strip $(shell perl -e '$$/=""; $$_=(grep {/^Package: $(DEB_PYTHON_MODULE_PACKAGE)$$/m;} (<>))[0]; /^Architecture: (.*)$$/m && print $$1' debian/control))
    ifeq (all, $(cdbs_python_module_arch))
    cdbs_python_current_version := $(strip $(patsubst python%, %, $(shell pyversions -d)))
    cdbs_python_build_versions := $(cdbs_python_current_version)
    else
    cdbs_python_build_versions := $(strip $(patsubst python%, %, $(shell pyversions -r debian/control | grep -E "^python[0-9.]+( python[0-9.]+)*$$")))
    endif

This means the information filled in the XS-Python-Version field is
only being used when the package is not Arch: all. This is wrong, for
there are python-only modules which will only work on Python 2.4 and
above, for example.

Maybe using the first version returned by pyversions -r debian/control
for the first case will do it.

Thanks,
