Hi Emacs,
It seems that running project-find-regexp fails over tramp. Any idea?
Thanks.
Here's the backtrace:

Hi!
How does it fail? Does it signal an error? I don't see that in the
backtrace.

It signals
--8<---------------cut here---------------start------------->8---
split-string: Wrong type argument: stringp, nil
--8<---------------cut here---------------end--------------->8---
The issue is that
--8<---------------cut here---------------start------------->8---
(apply #'vc-git--run-command-string nil "ls-files" args)
--8<---------------cut here---------------end--------------->8---
returns nil, in project--vc-list-files.
Does this help? Thanks.

Okay... Does it happen on one particular host, or with any directory
visited over Tramp?
I usually test Tramp functionality over the 'sudo' adapter.

BTW, is there any chance that you don't have Git installed on the remote
host?

I have, but Tramp was not being able to find it. I've solved that, but
now I'm stuck again...
--8<---------------cut here---------------start------------->8---
File is missing: /ssh:termux:/data/data/com.termux/files/home/repos/sbcl/.gitmodules
File is missing: Setting file times No such file or directory /data/data/com.termux/files/usr/tmp/tramp.sSmuQG
tramp-error: Setting file times No such file or directory /data/data/com.termux/files/usr/tmp/tramp.sSmuQG
--8<---------------cut here---------------end--------------->8---
It seems that Tramp isn't being able to read/write from the tmp
directory, but I can't figure out why. Also, I don't get why it
complains about the fact that a git repository has no .gitmodules file.
Any idea? Thanks again.

Looks like you use the termux sshd server on Android, right? This is
sometimes tricky; I'm discussing this configuration also in bug#57044.
Could you please try it again, starting with "emacs -Q" and making your
Tramp config manually, setting tramp-verbose to 10, and run the test?
The resulting debug buffer might tell us more.

Indeed, termux sshd server on Android. I'll investigate this further
and get back to you.
Dmitry, I tested project-find-regexp over Tramp with a "mundane" system
and it failed regardless. It seems I figured out why. Shell-file-name
(in xref-matches-in-files) seems to get its value from the local
machine, not from the remote one. Therefore, it can't possibly start
the grep process remotely. Any on how to fix this?
Thanks again.

Right.
Michael, do you perhaps have a suggestion how xref-matches-in-files
could use connection-local values for shell-file-name and
shell-command-switch (when available) without losing compatibility with
Emacs 26.1?

Hmm, the usual recommendation is to take
with-connection-local-variables, like
(with-connection-local-variables
(xref--process-file-region (point-min)
(point-max)
shell-file-name
output
nil
shell-command-switch
command))
Unfortunately, the macro exists since Emacs 27 only, so you need to test
its availablility, and to use progn instead if it doesn't exist.
There is another trap, Tramp sets already the connection-local variable
shell-file-name to "/bin/sh". The user must overwrite this (or Tramp
must be pimped up to take whatever the user declares as "remote-shell").
Best regards, Michael.

OK, I have just pushed a fix in commit 6edff5ac33 which will hopefully
fit the requirements.
Andre, please test.

Perhaps that's the value which is needed in this particular scenario?
E.g., no bash installed on that system.

In general, "/bin/sh" is a good idea. But André uses an Android device,
running termux. "/bin/sh" doesn't exist there. One can use
"/system/bin/sh" or "/data/data/com.termux/files/usr/bin/sh" (I believe,
haven't checked the latter).
Best regards, Michael.

Right, I suppose that would require customization.

Dmitry, it works for me. Thanks.
On which release will your patch be included? Emacs 29 or Emacs 28.2?

Emacs 29, but you will also be able to upgrade project.el separately, as
soon as I bump the package version (from GNU ELPA).
...and I have done that now (version 1.5.1). Please wait up to 24h for
the new version of the package to be released, and you can upgrade.

Thanks Dmitry. Please instruct me on how to close this bug.
