MED-123 recorder logs in app ui does not work on windows

[tribhuwan-kumar]

I'm trying to debug it, is it working on other OS ?

[louis030195]

yes on macos

[louis030195]

@tribhuwan-kumar is this issue still happening?

@tribhuwan-kumar is this issue still happening?

yup, i tried to debug it but got no clue what's causing this issue, i'll try to fix it again

still same

[tribhuwan-kumar]

@louis030195 i couldn't find what causing this issue :( the issue might be related to localforage

the only solution, i can think right now is writing a different recorder log viewer especially for windows or modifying this components logic for windows

[louis030195]

weird

just using tauri native event stuff https://v2.tauri.app/develop/calling-frontend/#listening-to-events

[tribhuwan-kumar]

@louis030195
the issue is with tauri's emitter
tauri-apps/tauri#8177
since log viewer is using tauri's listen to get emitted log but it fails in windows when there is high call rate. this same issue is also occurring when i tried to listen download status for #632

a member of tauri suggested this solution, i'll try to fix with it

log-viewer-v2.tsx

import { listen } from "@tauri-apps/api/event";

    const unlisten = listen<string>("sidecar_log", (event) => {
      setLogs((prevLogs) => {
        const newLogs = [...prevLogs, event.payload].slice(-100);
        localforage.setItem("sidecar_logs", newLogs);
        return newLogs;
      });
    });

    return () => {
      unlisten.then((f) => f());
    };

sidercar.rs

    tauri::async_runtime::spawn(async move {
        while let Some(event) = rx.recv().await {
            match event {
                CommandEvent::Stdout(line) => {
                    let log_line = String::from_utf8(line).unwrap();
                    print!("{}", log_line);
                    app_handle.emit("sidecar_log", log_line).unwrap();
                }
                CommandEvent::Stderr(line) => {
                    let log_line = String::from_utf8(line).unwrap();
                    error!("Sidecar stderr: {}", log_line);
                    app_handle
                        .emit("sidecar_log", format!("ERROR: {}", log_line))
                        .unwrap();
                }
                _ => {}
            }
        }
    });
