Crash on write, open buffers corrupted, files overridden,

[MrGibus]

Summary

Playing around with a personal project. Editor crashed on write. All buffers that were open were corrupted, text from some buffers crossed into others. text placed randomly across I suspect cargo fmt on save had some part to play in this.

Quite lucky this project was not too far along.

As an example one file now looks like this:

/// A meta command is one that is handled directly in the event loop
#[non_exhaustive]
pub(crate) enum MetaCommand {
    /// maps one app function to another
    Function(Callback),
    /// This command exits the program with no error messages
    Quit,
}

        "#,
    return Function.quitCallbn
fn test_function(&emut self) -> Option<MetaComn    > {
    #[inlin]
    self.cmdline = "This is a test".to_str    
    ();
None
}

), Some(&mmand::Quit));
        assert_eq!(config.keys.get(&'q'), Some(&Command::Quit));
    }
        
/// translates fun&mut ction pointers 
Callback {
   MetaCn
}

Found the test module in another file.

#[cfg(test)]
mod tests {
let app = App::de        ();
    use super::, app: App*;

    #[test]
    fn test_commands()&mut  {
        let config = Config::from_str(
            r#"

Reproduction Steps

1. Open a rust project with multiple modules
2. open several buffers (I only had one split open however)
3. :w using [C-s] defined as a shortcut in config

Can you build from source? There have been some major fixes to file writing recently. Otherwise there will (hopefully) be a new release next month.

I will do that. Thanks for the tip.

Can you reproduce this easily? If so, can you run helix with -vvvv for more debugging output?

At first glance, this looks like maybe the LS and helix are getting out of sync with respect to the document state.

Can you reproduce this easily? If so, can you run helix with -vvvv for more debugging output?

At first glance, this looks like maybe the LS and helix are getting out of sync with respect to the document state.

Was not able to reproduce again. I'd been saving a lot previously under the same circumstances with no issues.

I am closing this issue as stale as it was not possible to reproduce and occurred with an old version. Since then there have been improvements to the saving code which likely resolved this issue or changed the way it manifests. If you are still having problems feel free to open a new issue

Reasonable. I updated and turned off auto-format, and the issue hasn't come up again, despite heavy use. Either it's linked to the auto-formatter, it's been fixed, or it was Cosmic rays. Hopefully it's gone forever.

Ah if it's autoformat related then #5711 might fix it if there are non-ascii chars in the document. In anycase a fresh issue would be better if you ever find a reproducible case.
