bug#44953: lsof: LTlock test consistently fails (possibly due to btrfs)

[Mark H Weaver]

In the 'lsof' test suite, the 'LTlock' test consistently fails on my
system, possibly related to the fact that I use 'btrfs' for my local
filesystems.  Here's the relevant build log excerpt:

--8<---------------cut here---------------start------------->8---

The following commit made this into a fatal build error, which I agree
is an improvement:

  * gnu/packages/lsof.scm (lsof)[source]: Add patch to make test suite

Previously, the same test failure occurred on my system with lsof-4.91,
but the failure was ignored and I didn't notice it until now.  Before
that, our lsof-4.89 package did not run the test suite, so I do not know
if it had the same bug.

I should mention that 'gnome' depends on 'lsof' via the following
dependency path (among others):

gnome -> gnome-shell -> ruby-sass -> ruby-sass-spec -> ruby-terminfo ->
   ruby-rdoc -> ruby-rubocop -> ruby-parallel -> lsof

Thanks for the report!  I can reproduce this by formatting a btrfs 
image file and loop-mounting it to /tmp.

This looks like an upstream bug to me.  Do you have time to file 
one?  We're using the <https://github.com/lsof-org/lsof> upstream 
since Victor Abell retired.

Alternatively we could disable this test in Guix ‘for now’ with a 
comment--but we both know how long it will remain unfixed.

Side note: I tried to implement upstream's test workflow[0] but 
got new failures (i.e. we're not running all the tests yet).  I 
haven't tried fixing those yet.

Kind regards,

T G-R

Hi Tobias,

Thanks for the super quick response and for reproducing the bug.

> This looks like an upstream bug to me.

Agreed.

I have time, but there's another problem: it appears that I cannot file
a bug report on Github without first creating an account, which in turn
requires me to formally agree to their legal agreement.  Among other
things, it includes an indemnification clause, meaning that I would have
to promise to pay their legal fees if some dispute arises involving me
and they decide to retain laywers to deal with it.  They also claim the
right to change the terms of the agreement at any time without notifying
me, and by continuing to use the service I would implicitly agree to
those new terms.

I refuse to sign that agreement, which means that I cannot file bug
reports on Github.  Oh well.

I don't actually care about 'lsof', except for the fact that our 'gnome'
package depends on it.  For now, I'll just disable the 'lsof' test suite
on my private branch.

Sounds fine to me, unless someone who has already has a Github account
wants to use it to file a bug.

  Thanks again,
      Mark

My usual workaround to this is to do a shallow clone (git clone --depth
1) and look for frequently occuring email addresses in git log.
Then I just send the bug/patch to them. It hasn't failed so far.

[Maxim Cournoyer]

Hello,

For the record it seems Tobias had gotten around filing a bug here:
https://github.com/lsof-org/lsof/issues/152.

It seems the issue is real and a new Linux-specific tool lsfd is being
devised.  I guess we should disable the test, as the package is still
probably mostly functional on Btrfs, and wait for a proper resolution
from upstream?

Mark, could you share your patch disabling the test if you still have it
handy?

Thanks,

Maxim

Here's what I did on my private branch, which has diverged quite a bit
from master, so I don't know whether it will apply cleanly.

Hello again,

Mark, I've figured it out and disabled it locally.  Will push shortly to
core-updates-frozen.

Thanks!

core-updates-frozen was merged into master long ago :-)

Closing.
