Monocle plugin crash zellij

[0inp]

I just upgrade to monocle version 0.39, and invoking the plugin result in crashing zellij with the message Received empty message from server

I'm using zellij version 0.39.1

[imsnif]

Sorry for the experience! Could you please attach some logs?

There is a known issue about device files as mentioned in the readme - could this be related?

Hey ! Thanks for returning back to me ! I'd like to help ! Here's the part of the log file where I launch zellij and the monocle plugin: zellij.log

More information on my system:

Please don't hesitate if you want more info from me or if I can open a PR.

[imsnif]

Hum... not a lot of information there unfortunately. Could you share a bit how you loaded the plugin? What are the steps you did? Which folder did you start it in?

[0inp]

Here are the steps: 1 - Open Alacritty in the root ~ directory 2 - Ensure that there are no sessions with zellij kill-all-sessions and zellij delete-all-sessions 3 - Invoke zellij command 4 - Invoke the monocle plugin command (with one of the zellij plugin commands in the README or with the F1 keybind as stated in the README as well

[imsnif]

My suspicion is that this happens because of a certain file type we're not reading properly (the "known issue" in the README). Do you have device files in your home folder? Could you maybe try a few different folders (specifically with the F1 or Alt m keybinding) and see if it happens everywhere?

[0inp]

Yes, this happens in every directories (for example inside my dotfiles directory, in the section related to zellij, with only the config.kdl and other files in layouts, plugins and themes directories cf:

symlinks/config/zellij on  master [!]
➜ ls -T
.
├── config.kdl
├── layouts
│  ├── terminal.kdl
│  └── zjstatus.kdl
├── plugins
│  ├── forgot.wasm
│  ├── monocle.wasm
│  └── zjstatus.wasm
└── themes
   ├── catppuccin.kdl
   └── dracula.kdl

[imsnif]

Would you be comfortable compiling this plugin on your own and loading the resulting wasm file to see if it happens? This really shouldn't be a thing, but you never know...

Otherwise I'll try to provide you with some debug versions next week to help troubleshoot this. We don't get an error in the logs, so we'll have to do some guesswork before finding out what's wrong here.

[0inp]

I'm not an expert in Rust, so I don't really know how this work, I'm sorry 😅. Here's what I did:

• I cloned the repo
• I run zellij -l dev.kdl like stated in the README.md
• Unfortunately, the pane supposed to run the command cargo build && zellij action start-or-reload-plugin file:target/wasm32-wasi/debug/monocle.wasm failed with the cargo command not found error. which is weird since I installed rust.
• I quit that pane and in another one run the two commands separately:
• First cargo build which runs perfectly
• Then I load the plugin with zellij action start-or-reload-plugin file:target/wasm32-wasi/debug/monocle.wasm The zellij session crash with the same message. Here are the logs:

Well, I really don't know what's wrong with my config...

[imsnif]

Thank you very much for giving this a try even though you don't know the rust tooling!

I'm going on a conference next week, but the week afterwards I'm going to give you some debug builds for you to run without all this trouble so that we can troubleshoot this and find out what's going on. Thanks for your cooperation and patience!

For me it's also crashing on startup, also on a mac (m1).

These are the logs when running the dev.kdl:

I manually created a permissions.kdl by copying it from a working setup on linux and put it under /Users/y/Library/Caches/org.Zellij-Contributors.Zellij/permissions.kdl. And edited the path to the wasm binary on the mac.

There is no prompt like it shows in the screenshot of https://github.com/zellij-org/zellij/releases of 0.38.0 (yet before it crashes?).

It now doesn't display the Failed to read permission cache file: No such file or directory (os error 2) anymore. But still crashes zellij.

[Yzoni]

Strider also crashes btw, so the issue is not limited to this plugin.

[observer17]

encountered the same crash, I build a debug target and capture the stack when it crashed, hope it would be helpful.

[metaspace]

Just tried this out and zellij went to 800% cpu and core dumped when exiting :man_shrugging:

zellij plugin -- https://github.com/imsnif/monocle/releases/latest/download/monocle.wasm

Zellij 0.40.1 on NixOS 24.05.

[imsnif]

I have neglected updating this plugin for a long time. I promise to get back to it soon!!
