[Debian-med-packaging] Bug#904776: /usr/bin/dpkg-source: please parse d/t/control.autodep8 like d/t/control

[Paul Gevers]

Package: dpkg-dev
Version: 1.19.0.5
Severity: normal
File: /usr/bin/dpkg-source
X-Debbugs-CC: debian-ci at lists.debian.org, python-cobra at packages.debian.org
User: debian-ci at lists.debian.org
Usertags: issue
Control: affects -1 src:python-cobra

Dear dpkg maintainers,

In commit 90324cf support was added to dpkg-source to read debian/tests/control
files and convert all test dependencies into a Testsuite-Triggers field. This
works great and is used by britney to do unstable-to-testing migration
tests. However, we recently spotted a regression (in python-cobra) that was
missed, because it uses autodep8 with additional test cases. This is done in
line with the autodep8(1) man page¹:
'''
COMBINING AUTO-GENERATED TESTS WITH MANUALLY SPECIFIED ONES
       If `debian/tests/control.autodep8` exists, autodep8 will prepend the
       contents of that file to its own output. In that case, autodep8 will
       exit with a status of 0 even if no known package type is detected.
'''

It would be great if dpkg-source would also parse debian/tests/control.autodep8
in the same way as it does debian/tests/control, except I guess it should not
set the Testsuite field (as dpkg-source doesn't know which type of autopkgtest
this is).

I cloned the dpkg source, but as it is written in Perl, I felt uncomfortable
providing a patch. I may reconsider if this is found valuable nevertheless.

Thanks for all your good work.

Paul
