bash-lsp
LSP Hanging on Close, Freezing after a few seconds and then suddenly drawing a lot of system resources.
Code editor
Helix, Neovim
Platform
Unix
Version
5.0.0
What steps will reproduce the bug?
Opening my editor (Helix in this case) the LSP will start, it will make the usual corrections and suggestions... but then it will freeze within a few seconds, become unresponsive and start to eat up a ton of CPU power. It starts to sound like my PC is a helicopter attempting to takeoff. Then closing the editor, the editor will hang and throw an error that says "The LSP is unresponsive / did not close correctly"
How often does it reproduce? Is there a required condition?
Every single time I use bash-language-server and open a shell script. Disabling bash-language-server is the only thing that fixes the issue.
What is the expected behavior?
No response
What do you see instead?
LSP immediately freezing Hanging on Close Increased CPU usage by quite a lot
Additional information
No response
bash-language-server has been completely unusable. It continues to use extremely high CPU and hang indefinitely on close.
Holy fuck! Seems I fixed it. I deleted bashIde.globPattern ext. setting at all for all locatiions (User, Remote ..).
It was default value: **/*@(.sh|.inc|.bash|.command)
Now it is empty "bashIde.globPattern": ""
No CPU eating now. It seems a bug.
I even don't know the purpose of bashIde.globPattern. The extension still working as previous.
its using globbing to find files with those extensions so it can find/parse functions and variables in other files. **/* is recursive globbing and @(.x|.y|.z) is a capture group for things that end with those extensions. That could certainly take a lot of CPU, especially with a lot of sub-directories.
I'm not 100% sure if that came from bash-language-server (or vscode/another extension), but its good to know in-case anyone wants to bisect this issue across the last few versions.
I think it is a bug, because my Workspace contains only 10 small shell files.
I'm experiencing a related issue, not sure if it has the same RC. When opening any file on nvim that will trigger bash-lsp attachment AND editing and closing quickly, the behaviour described by the OP occurs i.e (Hanging on Close, Increased CPU usage by quite a lot). This completely locks-up my WSL machine.
It's definitely related as I have that same thing happen. The solution was to downgrade the version to the last major release. Im pretty sure this was introduced due to auto-bumped dependencies and the globbing pattern when it comes to larger directories.
Downgrading worked, will keep checking future releases for a fix, thank you, lain drinking purple monster!
This occurs for me on (Arch) WSL even with 4.10.2.
Edit: Also with 3.3.1. Was hoping to find a point to bisect from 😢 Edit 2: Using Neovim 0.9.5
