147-161: Improve disposal pattern and error handlingWhile changing to
ValueTaskis appropriate for disposal, there are some improvements needed:
- Empty catch block silently swallows exceptions
- Disposal pattern could be more robust
Consider this improved implementation:
public virtual async ValueTask DisposeAsync() { try { if (RPC != null) { try { await RPC.InvokeAsync("close"); } catch (RemoteMethodNotFoundException e) { + Log.Exception("Plugin doesn't support close method", e); } + catch (Exception e) when (e is not ObjectDisposedException) + { + Log.Exception("Error during plugin close", e); + } } } finally { - RPC?.Dispose(); - ErrorStream?.Dispose(); + if (RPC != null) + { + RPC.Dispose(); + RPC = null; + } + if (ErrorStream != null) + { + ErrorStream.Dispose(); + ErrorStream = null; + } } }

Line range hint 136-161: Verify impact on other plugins and implementations
The changes to both ReloadDataAsync and DisposeAsync methods could affect other plugins and implementations.
Let's verify the impact:
✅ Verification successful
Based on the search results, I can now provide a final response:
Changes to ReloadDataAsync and DisposeAsync are safe and properly implemented
The changes to both methods are part of the standard plugin lifecycle and follow the established patterns:
-
ReloadDataAsyncis properly implemented:- Only 2 classes implement
IAsyncReloadable:JsonRPCPluginV2andProgramplugin - The reload functionality is centrally managed through
PluginManager.ReloadDataAsync() - Error handling for missing remote methods is properly handled
- Only 2 classes implement
-
DisposeAsyncfollows correct cleanup pattern:- Proper error handling for remote method calls
- Ensures cleanup of RPC and ErrorStream in finally block
- Used by derived class
ProcessStreamPluginV2which adds its own cleanup
The changes maintain compatibility with the plugin system's reload and disposal mechanisms as documented in the interfaces.

Critical: Current implementation may lead to inconsistent plugin state
The current implementation has several issues that need to be addressed:
-
The method combines both restart and reload approaches incorrectly:
- It restarts the RPC connection via
SetupJsonRPC() - It attempts to call
reloadon the new connection - It doesn't call
initializeafter restart
- It restarts the RPC connection via
-
The
contextvariable on line 141 is undefined, which will cause a compilation error. -
Empty catch block silently swallows exceptions, making it difficult to debug issues.
Consider implementing one of these solutions:
public virtual async Task ReloadDataAsync()
{
+ // Solution 1: Restart with initialize
SetupJsonRPC();
+ await RPC.InvokeAsync("initialize", Context);
}OR
public virtual async Task ReloadDataAsync()
{
- SetupJsonRPC();
try
{
await RPC.InvokeAsync("reload", Context);
}
catch (RemoteMethodNotFoundException e)
{
+ Log.Exception($"Plugin doesn't support reload method", e);
+ // Fallback to restart + initialize
+ SetupJsonRPC();
+ await RPC.InvokeAsync("initialize", Context);
}

I think this should be consistent with the C# API, so |
There's a problem with the current implementation.
Reloadwill restart jsonrpc_v2 plugin, but not callinginitialize. This may break the plugin state that are not what plugin developer may assume.There are two solution:
initializewhenever reload.reloadrequest.This will be a breaking change regardless, but given the relatively small number of v2 plugin now it should be fine.
@Flow-Launcher/team which one would you think is better?
