Subject: bug#40650: guix test suite failures building Debian package

Hi Vagrant,

Vagrant Cascadian <[email-masked]> skribis:

> Any of the test suites that require networking will need to be disabled
> for Debian packages.

That should be fine.

> One thing that occurs to me is Debian systems have USER_NS_UNPRIVLEDGED
> disabled by default (enableable at run-time with
> /proc/sys/kernel/unprivileged_userns_clone).

That should be fine too: tests that rely on unprivileged user namespaces
are skipped when that’s missing.

> Attached is the test-suite.log, as requested.

Excellent!

Here’s it’s ‘search-bootstrap-binary’ from (guix tests) that tries to
create the file above, having downloaded it earlier.

For the ‘guix’ package in Guix, what we do is that this and related
files are inputs to the package; that way, they are not downloaded at
all upon ‘make check’ since they’re already there.

All you need is to ensure that
gnu/packages/bootstrap/*-linux/{bash,mkdir,tar,xz} exist, are
executable, and are statically-linked.  You could provide Debian
binaries if that’s more appropriate.

We may need to provide a dummy .gitconfig file or something here so we
can run these tests.  See also <https://issues.guix.gnu.org/issue/37679>.
(The same applies to several test failures.)

Thoughts?

Could you wrap the ‘scandir*’ and ‘scandir’ calls in ‘pk’, run:

  make check TESTS=tests/syscalls.scm

and send ‘test-suite.log’?

This test relies on network access + HTTPS certificates.  It does check
for the former but not the latter.  Any suggestions on how to do that?

Thanks,
