From: Shant Sukljian <sshantt <at> icloud.com> To: 37557 <at> debbugs.gnu.org Subject: bug#37557: 27.0.50; Tramp consistently causes Emacs to crash when quickly scrolling remote file Date: Sun, 29 Sep 2019 16:25:44 -0700
Whenever I scroll using the trackpad in a remote file, Emacs consistently crashes. (Also, other things crash Emacs in remote files, but this is the most common one I've come across) I have tried Emacs v27 and v26.3 and have seen no difference. I've cleaned up my entire init file and left only tramp in there. Here is what it looks like ``` ;; Initialize Package Archives (setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/") ("melpa" . "http://melpa.org/packages/"))) (package-initialize) ;; Install Straight & Use-Package (defvar bootstrap-version) (let ((bootstrap-file (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory)) (bootstrap-version 5)) (unless (file-exists-p bootstrap-file) (with-current-buffer (url-retrieve-synchronously "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el" 'silent 'inhibit-cookies) (goto-char (point-max)) (eval-print-last-sexp))) (load bootstrap-file nil 'nomessage)) (straight-use-package 'use-package) ;; Install & Configure tramp (use-package tramp :straight t :config (setq tramp-default-host "ss_analytics" tramp-default-method "ssh" tramp-ssh-controlmaster-options "")) ``` To recreate follow the following steps: ** Place the above in init.el ** Launch Emacs ** Find and open remote sql file that contains ~2,000 lines ** Rapidly scroll up and down with a trackpad In GNU Emacs 27.0.50 (build 1, x86_64-apple-darwin18.7.0, NS appkit-1671.60 Version 10.14.6 (Build 18G95)) of 2019-09-14 built on Shants-MacBook-Pro.local Repository revision: 52172d234015776bcc595c731477b98fa2949e50 Repository branch: master Windowing system distributor 'Apple', version 10.3.1671 System Description: Mac OS X 10.14.6 Recent messages: Tramp: Sending command ‘exec ssh -e none ss_jyve_analytics’ Tramp: Waiting for prompts from remote shell...done Tramp: Found remote shell prompt on ‘ss_jyve_analytics’ Tramp: Opening connection for ss_jyve_analytics using ssh...done No projects needed to be removed.
