[bug#59487,1/2] build-system/dune: Automatically deduce test-target in most cases.

guix/build-system/dune.scm (dune-build): tests? defaults to #f.
guix/build/dune-build-system.scm (check): Missing test-target is auto-detected.

Hi!

This LGTM, but maybe put test-target inside the cond too, so we can
remove the or?

I've looked at how opam does things, and this seems to be the norm:

["dune" "runtest" "-p" name "-j" jobs]

Maybe this would work better:

(apply invoke program "runtest"
       (append (if test-target (list test-target) '())
               ...))

WDYT?

Hi! Sorry, I missed these patches and only found them after realizing
that your Mirage patches require these.

I'm having trouble applying the second patch (of V2), maybe there have
been changes that cause conflicts? Could you rebase on master or just
resend the V2 patches to 59487@debbugs.gnu.org? Maybe with a short
comment if and how they address Julien's suggestion?

Sent a rebased V2 just now.  The runtest invocation looks like Julien's
suggestion, so I think I addressed it.
  

This removes the usage of the `test-target` argument from dune-build-system
completely. Dune automatically finds tests for packages being built. The
previous test-target was limiting the search of tests to specific folders. In
some cases the wrong folders.

I could not systematically check all affected packages, but have fixed tests
for some (these are packages for which previously we were not running tests).

base-commit: 9ad5c3deeaebfb6f953579992a082d8327730611
  

I was able to check the dependents, so pushed to master as
7686b68f6bb1ae5dc206178805c32bceceea3743 -
79bf3b54a64e304a29334b5029c24d942d9dc051.

Note that I moved patches around, to have the last one before removing
test-target. I merged patches 3, 4 and 5 because intermediate states
would have failing packages otherwise. Also, patch 5 had unrelated
changes to lablgtk3 which I droped, because the package still builds.
If that was intentional, please send a new patch for that :)

I also listed all modified packages in the commit message, and removed
the Co-authored line which listed the author already.

Thanks!
