when setting up the log reader for a device during `flutter run`, discard any `RPCError` thrown due to the device being disconnected #155049

andrewkolos · 2024-09-11T21:25:52Z

This PR contains some refactoring. To make the actual change easier to figure out, I've tried to separate parts of the change into multiple commits for easier reviewing 🙂.

I plan on cherry-picking this change to stable.

I'm aware of dart-lang/sdk@e099a00, but I don't think the new error code is exposed anywhere yet.

Yeah, it looks like we'll need to publish a new version of package:vm_service, but if we're going to be CP'ing this change this is probably sufficient for now.

Holding off on the cherry-pick.

I chatted with @jonahwilliams and did some quick experiments and figured out FlutterDevice.tryInitLogReader (formerly initLogReader) doesn't do what I thought it does. All it does is set the appPid field on the device's DeviceLogReader. The only reference of this I could find of appPid is

flutter/packages/flutter_tools/lib/src/android/android_device.dart

Lines 1192 to 1199 in 7292c94

    
           } else if (appPid != null && int.parse(logMatch.group(1)!) == appPid) { 
        
             acceptLine = !_surfaceSyncerSpam.hasMatch(line); 
        
             if (_fatalLog.hasMatch(line)) { 
        
               // Hit fatal signal, app is now crashing 
        
               _fatalCrash = true; 
        
             } 
        
           } else {

For context (though I'm no expert here): To get logs from Android, we need to use adb logcat; but gives us more than just the logs from the Flutter app. That's why we need this extra logic to filter out all of the noise.

Why this matters. For users not running apps on Android, the error message I introduced would be pointless and confusing noise.

I'll see if there is a way to relocate this tryInitLogReader away from the general ResidentRunner workflow and over to the Android side of things. If that fails, I can at least update the error message to be less confusing (as-is, the message implies that logging won't work, but in reality it still will—though the Android workflow might become unstable if the device is running other apps...hmm, maybe we should throwToolExit in that case...).
