bug: switching between neovim stable|nightly errors with "cannot load incompatible bytecode"

[ibhagwan]

Did you check docs and existing issues?

• I have read all the lazy docs
• I have searched the existing issues of lazy
• I have searched the exsiting issues of the plugin I have a problem with

Neovim version (nvim -v)

0.8.1

Operating system/version

Linux

Describe the bug

When cache is enabled trying to use the nightly appimage results in the error:

E5108: Error executing lua ....local/share/nvim/lazy/lazy.nvim/lua/lazy/core/cache.lua:134: /home/bhagwan
/.local/share/nvim/lazy/lazy.nvim/lua/lazy/core/util.lua: cannot load incompatible bytecode

        [C]: in function 'require'
        [string ":lua"]:1: in main chunk

Steps To Reproduce

1. Setup lazy nvim with neovim 8.1 and cache enabled
2. Start neovim 0.8.1
3. Download curl -LO https://github.com/neovim/neovim/releases/download/nightly/nvim.appimage
4. Start the appimage with chmod a+x nvim.appimage && nvim.appimage

Expected Behavior

Auto-detect the compiled bytes are a from different neovim version and regenerate cache when switching between stable and nightly.

I can not reproduce this. I've added jit.version to the cache version string, but both 0.8.1 and nightly already use the same version of jit.

Was the 0.8.1 version linked to puc instead of jit maybe? If so you should now get an errro instead that you need to have a neovim version built with luajit

Still getting the same exact error unfortuntaely.

Neovim 0.8.1 version output:

Your LuaJit version is exactly the same between both. Is there anything else special about your installation? Where did you get the 0.8.1 from? Is that also appimage?

My 0.8.1 comes from the void linux packages (prebuilt binaries), I will download the 0.8.1 appimage, clean and reinstall lazy and see if that makes any difference.

[ibhagwan]

Ok, so I downloaded the 0.8.1 appimage, deleted the ~/.local/share/nvim/lazy and ~/.local/state/nvim/lazy folders and I'm getting the same errors only this time multiplied by the number of plugins, seems like the compiled bytecode from the appimages isn't able to load even when compiled by it's own appimage binaries:

You need to delete ~/.cache/nvim/lazy/cache

[ibhagwan]

You need to delete ~/.cache/nvim/lazy/cache

Oops I guess I missed that, so switching between the 0.8.1 and 0.9 appiamges works with no issue but as expected I can't switch between the appimage and my local 0.8.1 binaries.

I can workaround this by doing a simple test (in the code) and deleting ~/.cache/nvim/lazy/cache if need be, not sure if this is worth your time.

[folke]

I just pushed a change that should fix the incompatible byte code as well

[folke]

Can you see if the new version works without issues?

[ibhagwan]

Just tested, worked like a charm :-)

Tyvm!
