Random crashes when plugin is active

[qkzk]

Hello,

Neovim crashes when entering insert mode in a function. It only happens when the plugin is active and in Python. The logs don't show much, all I have is :

~/.cache/nvim/log

WARN  2022-06-29T18:49:36.462 97125 deadly_signal:177: got signal 1 (SIGHUP)

I can't find anything else in any logs...

Do you have any idea about that ?

Is that randomly? Could you add the function prototype/signature and the code snippets when the crash happened? Also the neovim version as well. Btw, there are signature logs as well. In your config:

  debug = true, -- set to true to enable debug logging
  log_path = vim.fn.stdpath("cache") .. "/lsp_signature.log", -- log dir when debug is on
  -- default is  ~/.cache/nvim/lsp_signature.log
  verbose = true, -- show debug line number

TBH, I think it might be because LSP does not handle the signature requests properly.

Thanks!

It's not random, it happens all the times when I call this method with lsp signature active :

Here is the method I was calling when neovim crashed :

    def register(self, module, *args, **kwargs):
        """
        Register a new module.

        :param module: Either a string module name, or a module class,
                       or a module instance (in which case args and kwargs are
                       invalid).
        :param kwargs: Settings for the module.
        :returns: module instance
        """
        from i3pystatus.text import Text

        if not module:
            return

        try:
            return self.modules.append(module, *args, **kwargs)
        except ImportError as import_error:
            if import_error.name and not import_error.path and isinstance(module, str):
                # This is a package/module not found exception raised by importing a module on-the-fly
                return self.modules.append(Text(
                    color="#FF0000",
                    text="{i3py_mod}: Missing Python module '{missing_module}'".format(
                        i3py_mod=module,
                        missing_module=import_error.name)))
            else:
                raise import_error
        except ConfigError as configuration_error:
            return self.modules.append(Text(
                color="#FF0000",
                text=configuration_error.message))

Here is the caller where the crash happened :

status.register(
    "disk",
    path="/",
    # format="{used}/{total}G [{avail}G]",)
    format=" ⛁ {avail}  GiB ",
)

The method comes from i3pystatus more precisely : here

I'm using Neovim 0.7.0-3 from Pacman (Manjaro with i3).

I was updating my setup since I'm on holiday :)

I'll look at the logs and try to reproduce.

What is you python LSP?

I did not see crash.

Nice theme :) It's pyright, which is fully updated :/

[qkzk]

I can't produce logs :/

here is how it's configured :

{
        "ray-x/lsp_signature.nvim",
        event = "BufRead",
        config = function()
            require "lsp_signature".setup({
                debug = true, -- set to true to enable debug logging
                log_path = "/home/quentin/.cache/lvim/lsp_signature.log", -- log dir when debug is on
                -- default is  ~/.cache/nvim/lsp_signature.log
                verbose = true, -- show debug line number
            })
        end
    }, -- function signature while inserting

And the autocommand :

    { "BufWinEnter",
        { pattern = { "*.py", "*.go", "*.rs", "*.js", "*.c" }, command = "lua require('lsp_signature').on_attach()", }, },

But no log is written to given file. As you can see I declared an absolute path and created the file with my user to be sure. The file stays empty.

I guess the problem is from lunarvim itself, since it quite an heavy configuration.

I have a new line in lsp.log everytime :

[WARN][2022-06-30 08:10:05] .../lua/vim/lsp.lua:812     "server_request: no handler found for"  "workspace/diagnostic/refresh"

I am using pyright as well. The warn logs is fine. In lsp_signature/tests folder, there is a init_pack.lua , you can take a look and check if that config works for you. Also, neovim release version is currently 0.7.2. Worth an update.

Hello,

Tried with last stable 0.7.2.0 and dev 0.8.xx version of Neovim and the crash still occurs.

Tried with a minimal setup and no crash so I guess it's a conflict somewhere in my config :/

Won't be easy to figure it out :)

[qkzk]

!!! Found it :)

It's the terminal emulator...

When I enter a function with no signature provided, lsp_signature displays an emoji :panda_face: For some reason, my terminal emulator (st) can't display it and crashes.

When I used Alacritty it didn't crash...

:) I guess I'll have to recompile st.

I thought about it since I tried to display the logs with less and it crashed... it didn't when I opened them with tail who skipped some of it.

[qkzk]

Well, I only had to install ttf_symbola to fix it. Ref

Thanks for the support ray-x :+1: was much appreciated

[ray-x]

I did not know nerdfont/emoji will crash the neovim. Will update the readme. Thanks for the update!
