I'm going to assume the lack of reply is because the problem doesn't happen anymore. It doesn't in my tests, but my remote language server in the remote $HOME doesn't rely on PATH to figure out the toolchain and thus doesn't suffer from this vulnerability. Closing. If the problem persists, we can reopen. João

From: jeberger <at> free.fr To: bug-gnu-emacs <at> gnu.org Subject: 27.2; Eglot should use shell-file-name when launching the language server for a remote file Date: Fri, 24 Feb 2023 08:39:45 +0100 (CET)From https://github.com/joaotavora/eglot/issues/1175 # Steps to reproduce: - On the remote machine: - Install a language server in a non-standard path (e.g. `rust-analyzer`, which installs in a subdirectory under `$HOME` and not `/usr/bin`) - Make sure that the server is in the path for a shell other than `sh` (e.g. set the path in `.zprofile` for `zsh`). - On the local machine: - Open a file remotely through TRAMP - Set `shell-file-name` to the shell you're using on the remote (e.g. `(setq shell-file-name "zsh")`) - <key>M-x</key> `eglot`. # Expected result: Eglot should start # Actual result: Eglot asks `Enter program to execute (or <host>:<port>):`, then when I type `rust-analyzer` it fails with message `[jsonrpc] Server exited with status 127`. Looking at `eglot-events-buffer`, it is clear that eglot tried to use `sh` to start the server. # Partial fix The server starts correctly if I change function `eglot--cmd` to use `(or shell-file-name "sh")` instead of plain `"sh"`, e.g.: ```lisp (defun eglot--cmd (contact) "Helper for `eglot--connect'." (if (file-remote-p default-directory) ;; TODO: this seems like a bug, although it’s everywhere. For ;; some reason, for remote connections only, over a pipe, we ;; need to turn off line buffering on the tty. ;; ;; Not only does this seem like there should be a better way, ;; but it almost certainly doesn’t work on non-unix systems. (list (or shell-file-name "sh") "-c" (string-join (cons "stty raw > /dev/null;" (mapcar #'shell-quote-argument contact)) " ")) contact)) ``` It still fails to autodetect the server and asks for the program to execute though. ---- In GNU Emacs 27.2 (build 1, x86_64-w64-mingw32) of 2021-03-26 built on CIRROCUMULUS Repository revision: deef5efafb70f4b171265b896505b92b6eef24e6 Repository branch: HEAD Windowing system distributor 'Microsoft Corp.', version 10.0.19042 System Description: Microsoft Windows 10 Enterprise (v10.0.2009.19042.2604) Recent messages: Cleaning up the recentf list...done (0 removed) Quit Cleaning up the recentf list...done (0 removed) Timer #[257 "\303!\205!\0r\211q\210\203 \0 \203 \0\304\305\306\307 $\210\310\311!\210\312\211)\207" [flymake-mode flymake-no-changes-timeout flymake-timer buffer-live-p flymake--log-1 :debug flymake "starting syntax check after idle for %s seconds" flymake-start t nil] 6 " (fn BUFFER)"] ran for 00:00:17 from 08:15:39 to 08:15:56 Couldn’t find local shell prompt for C:/ProgramData/chocolatey/lib/Emacs/tools/emacs/libexec/emacs/27.2/x86_64-w64-mingw32/cmdproxy.exe Cleaning up the recentf list...done (0 removed) Timer flycheck--handle-idle-trigger ran for 00:00:49 from 08:15:38 to 08:16:27 Auto-saving...
