The 'proced-refine-test' test seems flaky to me, e.g.

"""
Test proced-refine-with-update-test condition:
    (ert-test-failed
     ((should (or pid-equal (when ... ... ...))) :form
      (or pid-equal

On re-runs, sometimes just proced-refine-test fails. I've attached
proced-tests.log.

bug#73441: 31.0.50; Unstable proced-refine-test failure

[Laurence Warne]

[-- Attachment #1: Type: text/plain, Size: 405 bytes --]

Hi,

I can't seem to reproduce despite running them for a while continuously.
Would you be able to share the contents of the Proced buffer before and
after the refinement in a flakey test run in addition to the PID refined on?

It might also be worth testing proced-refine works as expected for you when
refining by PID (in case the flakiness is hinting at some kind of
legitimate bug)?

Thanks, Laurence

FTR, the issue happens more often (always?) on emba. gnu.org, see for
example <https://emba.gnu.org/emacs/emacs/-/jobs/91334>. I'll try to
hunt it in that environment, although I cannot promise anything.

I've instrumented proced-tests.el on emba. There was a failing
proced-refine-with-update-test. The *Proced* has shown the contents

That is, the first process is the parent of the second process, and the
second process is the parent of the third process. However, the test
assumes, that the first process is the parent of all following
processes

Does this information helps? Do you need more instrumentation on emba?

[-- Attachment #1.1: Type: text/plain, Size: 717 bytes --]

Hi Michael,

Thanks for taking a look!  Ah I see, I thought that refining on the PID of
a process only filtered the buffer to show the process and it's direct
children but looking at 'proced-filter-children' this doesn't appear to be
the case.

I've attached a patch which changes the refinement tests to use the simpler
CPU refinement behaviour (keep everything with %CPU >= process at point),
which appears to work well.

On the downside, whilst running the new tests I noticed an occasional flake
with the 'proced-update-preserves-pid-at-point-test' test.  Unfortunately I
still can't find the root cause after debugging it for a while so I've
marked it as unstable in the patch for now as well.

Thanks, Laurence

Subject: [PATCH] Fix flakey proced refine tests (Bug#73441)

* test/lisp/proced-tests.el (proced-refine-test)
(proced-refine-with-update-test): Use the much simpler CPU refinement
for testing 'proced-refine'.  The previous tests made the incorrect
assumption that refining on the PID of process A only filtered the
buffer to contain process A and its children, whereas in actuality
the children of process A's children, their children, and so on will
also be shown.
(proced-update-preserves-pid-at-point-test): Mark as unstable.

Eli, can this go to emacs-30, or should it be for master?

Thanks again. If you like we could instrument proced-tests.el in order
to hunt this on emba? Just say if so.

OK. So I'll just wait for the maintainer's flag where to push your other

If it only affects the test suite, then emacs-30 is okay.

I'll reopen this bug, because on emba there's still an error, occasionnally:

[-- Attachment #1.1: Type: text/plain, Size: 562 bytes --]

Hi Michael,

Sorry it looks like I might have overlooked the case where a process has an
empty column for %CPU.  It sounds a bit strange and I can't reproduce it
(as in a process having a blank entry - though I'm guessing it's platform
dependent), but proced-refine appears to respect processes having a blank
entry for %CPU and include them so I guess it's correct to do so in the
tests too?

In the attached patch I also added an ert-explainer to the proced refine
tests so we should get info on the process that failed if it comes up again.

Thanks, Laurence

(proced--assert-process-valid-cpu-refinement): Return t if the cpu
argument is nil.  'proced-refine' when applied to cpu will include
empty values, so by also checking nil we account for that possibility.
(proced--assert-process-valid-cpu-refinement-explainer): New function
for explaining refinement test failures in greater detail.

Are you sure that this problem us due to a blank entry for %CPU? Is this
foreseen, or is this an error in proced-refine?

This I would like to know first.

Excellent idea!

I've pushed your patch to the emacs-30 branch, because first I'd like to
see how a blank entry for %CPU in proced-refine looks like. I've removed
the '(or (null cpu)' part in proced--assert-process-valid-cpu-refinement
in order to see the buffer. I've also adapeted
proced--assert-process-valid-cpu-refinement-explainer for better
formatting.

Based on the results of the next failing test we can decide how to continue.

Best regards, Michael.

No I'm not sure at all (:.  Your suggestion sounds good to me, let me know
what it turns up!
