1. emacs -Q
2. C-x d /ssh:some-remote-host:/some/dir RET
3. Mark any file with `m'
4. A . RET
Expected: File is searched for regex `.'
Actual: user-error: Search failed with status 1: find: ‘/ssh:some-remote-host:/some/dir/file’: No such file or directory
This is probably because `xref-collect-matches' calls
`call-process-shell-command', which doesn't work remotely. It should
call `process-file-shell-command' instead.

Yes, this must be changed. But the file name needs some massage, too.
The appended patch fixes this for me. But since I don't know xref.el in
detail, I fear I introduce collateral damages. At least a second opinion
about the patch would be welcome, before I commit it to master.
Best regards, Michael.

The patch doesn't look dangerous to me, so you can go ahead and install,
thank you.
There is, however, a possible inconsistency: it touches
xref--collect-matches-1, which is used both in xref-collect-matches and
xref-collect-references. And you only changed the former function.
Could you check that M-x xref-find-references didn't work on remote
directories before your patch anyway? If it did, though, please make
sure that it continues to do so.
Bonus points for fixing it, at least when Grep is used (the relevant
file is lisp/cedet/semantic/symref/grep.el).

It doesn't work, indeed. symref/grep.el isn't aware of remote processes
(it uses call-process, for example). I've fixed this with the appended
additional patch.
Is it OK now to commit?

PS: Philipp, I'm kinda frustrated that you never confirm bug fixes.

Confirmed, thanks.
[In general there's no need to wait for my confirmation, I'm not doing

Usually, I work on Tramp problems. The local configuration isn't
important, what matters is almost always the remote host, which causes
the trouble. That's why I ask for confirmation.
(Acknowledged, it was a local problem in this case.)
Best regards, Michael.

Maintainers, would it be OK to backport this patch to the release
branch? This worked in Emacs 24.3 (which didn't use Xref), and the
patch is simple.

Sorry, no. The patch touches places that are used by too many
features, and I disagree that the patch is simple: replacing
call-process with process-file is never "simple".
We lived with this since Emacs 24.4, we can live with it some more.

I believe the patch is harmless. But of course, I respect your decision.
