C-r Restore Exiting - Githubissues

Tmux was working fine until a few weeks ago when I suddenly started getting exiting (not errors) when using C-r to try and restore. C-s still works, writes to the symlink last and everything seems to be okay, but when I try to resurrect even the simplest setup:

pane    0   1   :which  1   :*  1   :/Users/tiny/.tmux/plugins/tmux-resurrect   1   zsh :-zsh
window  0   1   1   :*  b9bd,158x52,0,0,0
state   0

I just end up outside tmux looking at:

[exited]

And the session has been killed (i.e. exited out) and I have no other error or warning information.

Hm.. this is pretty weird.

Which tmux version are you running? Is it like the "absolute latest built from source" or something?

It's the homebrew version of tmux, which, to my understanding, isn't on the be bleeding edge. Since tmux hasn't updated, might it be interference with zsh, which has had a few updates recently?

Hmm, no, I changed my shell to bash and the problem persists.

Thought I might add my 2 cents.

I had exactly the same issue for a few months (thinking maybe an update to tmux from brew or an update to this tmux-resurrect plugin would eventually fix the issue)

When I had the following flag: set -g @resurrect-capture-pane-contents 'on' it would exit on restore.

Eventually traced through the shell script for restoration (https://github.com/tmux-plugins/tmux-resurrect/blob/master/scripts/restore.sh)

and traced it to the function pane_creation_command() where it executes the tmux default command (https://github.com/tmux-plugins/tmux-resurrect/blob/master/scripts/restore.sh#L111)

Turns out I had the following in my .tmux.conf file : set-option -g default-command "exec reattach-to-user-namespace -l $SHELL which resolved to: cat '~/.tmux/resurrect/pane_contents//pane-0:1.1'; exec exec reattach-to-user-namespace -l /usr/local/bin/bash This was to get pbcopy and pbpaste working in tmux (from https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard)

Notice the double exec In the end I just changed my .tmux.conf to: set-option -g default-command "reattach-to-user-namespace -l $SHELL"

Seems to work now although some of the custom window names seem to go back to default Can live without that though.. a lot better than before when it was just exiting out after attempting to restore.

EDIT: I fixed this issue. It had to do with a path issue which was caused when mounting a directory into the docker container. My homedir was a subdirectory of a symlink, so in my main system there were two valid paths to ~ (and in particular, to the files that resurrect used to recreate my session). When I mounted my homedir into the docker container, the path that resurrect used became invalid, so my various panes couldn't be restored.

Bumping this issue to say that I'm encountering similar behavior, on tmux 2.1. However, it only occurs for me in an interaction with docker: Only if I save a file outside a docker container, and try to restore it inside the container (the only combination I really want), do I get this crash. I can save a file inside the container and restore it inside, save inside and restore outside, and save outside and restore outside, all just fine. Whether inside or outside the container, it appears that ctrl-S correctly saves the session to last. I've tried this both with and without continuum installed.

Another interesting behavior is that I only get a crash if I attempt to restore in a new session- I imagine this has to do with the new session special case ("The single exception to this is when tmux is started with only 1 pane in order to restore previous tmux env. Only in this case will this single pane be overwritten. "). If I try to restore from an existing session, I'll get the restore message in the status bar but my tmux session will remain the same (no changes).

This behavior seems pretty similar to https://github.com/tmux-plugins/tmux-resurrect/issues/91, and also a bit like https://github.com/tmux-plugins/tmux-resurrect/issues/98, but the fixes for these haven't worked for me (in particular, no default command to break things).

Example restore file that this behavior occurs on:

pane    0   1   :bash   0   :-  1   :/work/home/shawnghu    1   bash    :                                                                                                                                       
pane    0   2   :bash   1   :*  1   :/work/home/shawnghu    0   bash    :   
pane    0   2   :bash   1   :*  2   :/work/home/shawnghu    1   bash    :   
window  0   1   0   :-  b29d,208x60,0,0,0
window  0   2   1   :*  f41d,208x60,0,0{104x60,0,0,1,103x60,105,0,2}
state   0

I saw this today for the first time after years of using tmux / tmux-resurrect without issues. I'm running 3.0a from the Ubuntu 20.04 official apt package running inside of WSL 2.

I'm not 100% sure on this but I think this happens if the symlink to last is pointing to a file that's 0 bytes. I was able to fix the problem by manually symlinking last to the most recent non-empty restore txt file.

You can check / fix this by:

Goto cd ~/.tmux/resurrect
Run ls -la
Check to see if last is pointing to a 0 byte file
If so, look for the latest non-empty restore txt file and copy its file name
Run ln -sf $LASTEST_NON_EMPTY_FILE last to update last to your latest non-empty file
Launch tmux
Restore with leader + CTRL + r

I don't know how the most recent version of a resurrect restore file ended up being 0 bytes but the above let me restore from a fairly recent save and it no longer immediately exit out with [exited].

Having the same issue right now, still don't understand what the big problem is :(. I'm running tmux 3.5_a-1 with the following config:
