Strange. The commit was about tramp-adb.el and tramp-tests.el
(tramp-test29-start-file-process and tramp-test30-make-process). None
of the changes are related to tramp-test18-file-attributes.

And I cannot reproduce the problem locally. Nor does it happen on emba.

Could you pls rerun the Tramp tests by calling 'make -C test tramp-tests'
in order to be sure?

Best regards, Michael.

Oh, sorry, I should have made it clear that this commit just happened to 
be when I ran the test. I suspect the problem predates the commit by 
some time. I run 'make check' only fitfully and often skip reporting 
Tramp failures as they happen so often. I was not lazy-as-usual today.

It still fails, and running the Tramp tests that way (as opposed to 
'make -j12 check') causes several other tests to fail (compressed shell 
transcript attached).

No Tramp test failure shall happen, at least in the default case. It
would help much if you could report them in time, this is good for
identifying problematic commits.

Yes, the former runs only the default tests, while the latter runs also
expensive tests.

Could you pls instrument tramp-tests.el like appended? Run

--8<---------------cut here---------------start------------->8---
# make -C test tramp-tests.log SELECTOR='(or tramp-test18-file-attributes tramp-test41-special-characters)'
--8<---------------cut here---------------end--------------->8---

and send the resulting tramp-tests.log file.

Best regards, Michael.

Sorry, you didn't instrument tramp-tests.el as suggested last
message. So I cannot say anything yet.

Furthermore, there is bug#79956. The suspicion is, that new coreutils
defaulting to rust might be the problem. Do you run such coreutils?

Best regards, Michael.

Sorry, I missed that patch. Revised log attached. This is using the 
current commit ab7ed33f6dc8965da22f1200ccfacc1899064fd2 along with that 
patch and the above 'make' command.

I try not to, by prepending to PATH a directory where 'stat' is a 
symlink to '/usr/bin/gnustat', and similarly for every other coreutils 
program. However, I now see that the above tests sometimes ignores this 
part of my PATH, as it uses uutils versions of these programs anyway.

I suppose Tramp could work around the Ubuntu uutils bug by prepending 
"gnu" to every coreutils command name, and trying that first. It would 
need to do this only once, for the entire set of programs shared between 
uutils and coreutils. This would work, though, only so long as Ubuntu 
ships with GNU coreutils along with uutils.

Alternatively, the Tramp tests could see whether it's using uutils and 
if so, skip the tests.
