28.0.50; tramp-sh.el uses mknod file p which is not available on macos |
|
Date: |
Thu, 23 Sep 2021 08:29:53 +0200 |
I'm trying to use eglot over tramp using `emacs -Q -f package-initialize
-L /path/to/my/eglot -l eglot.el`. From what I understand, to
capture the remote process stderr, tramp creates a fifo, in
`tramp-sh-handle-make-process`, `tramp-sh.el:2889`. The MacOS mknod
command does not support the "p" parameter, so the communication with
the process does not work. Also no error is reported while the mknod
command is failing. I tried replacing `mknod %s p` with `mkfifo %s` or using
gnu coreutils mknod. This
fixes the fifo creation but the process communication is still
broken after that.
I can reproduce the problem with
(let ((default-directory "/ssh:macos-laptop:"))
(make-process
:name "TEST"
:buffer "*TEST*"
:command '("sh" "-c" "while sleep 1; do echo $(hostname) out; echo
$(hostname) err >&2; done")
:connection-type 'pipe
:coding 'utf-8-emacs-unix
:noquery t
:stderr (get-buffer-create "*TEST stderr*")
:file-handler t))
And it works correctly with
(let ((default-directory "/ssh:localhost:"))
(make-process
:name "TEST"
:buffer "*TEST*"
:command '("sh" "-c" "while sleep 1; do echo $(hostname) out; echo
$(hostname) err >&2; done")
:connection-type 'pipe
:coding 'utf-8-emacs-unix
:noquery t
:stderr (get-buffer-create "*TEST stderr*")
:file-handler t))

Thanks, this looks like expected. So I have adapted tramp-tests.el, and
pushed it to master. Closing the bug report.
As you know, I have no macOS machine for testing. Perhaps you could run
the whole test suite, and see whether there are problems? The call is
$ env REMOTE_TEMPORARY_FILE_DIRECTORY='/ssh:laptop.lan:/tmp' make -C test
tramp-tests
Thanks, and best regards, Michael.
