Hi! I have noticed self-check failures of libidn on ArchLinux:
https://gitlab.com/libidn/libidn/-/jobs/932649011
The gnulib self-tests that fail are: test-binary-io.sh test-perror.sh
test-init.sh
https://gitlab.com/libidn/libidn/-/jobs/932649011/artifacts/file/libidn-1.36a/b/gltests/test-binary-io.sh.log
https://gitlab.com/libidn/libidn/-/jobs/932649011/artifacts/file/libidn-1.36a/b/gltests/test-perror.sh.log
https://gitlab.com/libidn/libidn/-/jobs/932649011/artifacts/file/libidn-1.36a/b/gltests/test-init.sh.log
Essentialy it boils down to:
../../gltests/test-binary-io.sh: line 8: cmp: command not found
test-init.sh: failed test: err not empty: ../../gltests/init.sh: line 648: cmp: command not found
../../gltests/test-perror.sh: line 14: diff: command not found
I was a little surprised ArchLinux do not have cmp/diff by default, but
I was surprised that nothing except these gnulib tests failed.
I am reading gnulib's DEPENDENCIES which says:
* The comparison utilities 'cmp' and 'diff'.
+ Mandatory. Using the platform's native utilities gives good portability
exposure, but you can also use GNU diffutils.
+ Homepage:
https://www.gnu.org/software/diffutils/
I read the DEPENDENCIES file a bit more careful after noticing that it
has several mandatory dependencies that I find questionable, and I
noticed this in the beginning:
The following packages are needed by maintainers for using
'gnulib-tool'.
It doesn't say the packages are required for users building gnulib-based
packages. I can live with having diffutils installed as a maintainer.
Was this subtle distinction intentional?
I sympathize with ArchLinux's decision to be minimal, so my preference
is to make things work when it appears to be so simple.
What do you think about rewriting these self-tests to avoid cmp/diff?
Does anyone know a good portable shell-based idiom for comparing files
instead of using cmp/diff?
I'm posting this instead of just fixing the self-tests because I have a
suspicion this has been discussed, and maybe it is time to revisit it.
/Simon
