Package: autopkgtest
Version: 5.12.2~6.gbp89ad39
Severity: wishlist

Dear Maintainer,

with the latest and greatest changes in dpkg, I think it would be nice
if autopkgtest followed suit. Particularly, it would be advantageous to
support running and building tests in autopkgtest under build profiles
(esp. nodoc!). This would allow for smaller test footprint, less
packages to pull (ie. you don't need texlive on the testbed), and faster building of the packages.

I prepared a patch implementing such a change here: https://salsa.debian.org/jpalecek-guest/autopkgtest/-/commit/6275da59305d6e836cb3558f9f442479eb24fc95

The patch is functional, albeit incomplete due to missing documentation.

The real issue is the control file format. In my patch, I use an extra
stanza to specify build profiles, like this:

Build-Profiles: nodoc

Tests: run-some-tests
<<<

I chose this format, because adding the specification to some of the
tests would be IMHO misleading: the build profile applies to all of the
tests indiscriminately, not to any particular one. Also, I chose to
apply them to all @builddep@ dependencies as well.

However, there is a problem about this: it makes the control file format non-backwards-compatible. Particularly, dpkg needs to be patched or it
will croak on packages with such d/t/control. Maybe, some artificial
Tests: line like

Tests: *

could be added? That would make the change backwards compatible. Dpkg
still needs to be patched, but the change would be rather minimal.

What do you think about this proposal? Please comment here or on
salsa. I'm also CC-ing the dpkg developers, since it concerns them.

Regards
Jiri Palecek
