<!-- suggestion --><details><summary>[possible issue] Safely handle async init task</summary>
___
✅ Safely handle async init task
**The async call to fetch configuration is fire-and-forget, which can swallow exceptions and race with code that depends on _blobConfig. Capture the task and log exceptions, or await during startup. If startup cannot be async, store the task and handle its exceptions on a background continuation.**
[WelsonJS.Toolkit/WelsonJS.Launcher/ResourceServer.cs [45-57]](https://github.com/gnh1201/welsonjs/pull/318/files#diff-818c326b0529d19f21de13c9a00464e3eaacb0de06acbbc0bcea444e1cd3bef8R45-R57)
```diff
public ResourceServer(string prefix, string resourceName, ICompatibleLogger logger = null)
{
_logger = logger ?? new TraceLogger();
_prefix = prefix;
_listener = new HttpListener();
_resourceName = resourceName;
- // Fetch a blob config from Internet
- FetchBlobConfig().ConfigureAwait(false);
+ // Fetch a blob config from Internet (safe fire-and-forget with logging)
+ _ = FetchBlobConfig().ContinueWith(t =>
+ {
+ if (t.IsFaulted)
+ {
+ _logger?.Error($"FetchBlobConfig failed: {t.Exception}");
+ }
+ }, TaskScheduler.Default);
// Add resource tools
_tools.Add(new ResourceTools.Completion(this, _httpClient));
_tools.Add(new ResourceTools.Settings(this, _httpClient));
```
Suggestion importance[1-10]: 6
__
Why: The suggestion correctly identifies a "fire-and-forget" async call in a constructor, which can lead to race conditions for code depending on `_blobConfig`, a valid and important architectural concern.

___
✅ Make trace listener setup safer
**Adding a listener in a static constructor risks duplicate listeners if multiple AppDomains or re-initializations occur and can throw if file is locked. Guard against duplicates and wrap setup in try/catch to avoid crashing logging initialization.**
[WelsonJS.Toolkit/WelsonJS.Launcher/TraceLogger.cs [17-24]](https://github.com/gnh1201/welsonjs/pull/318/files#diff-1c64dc458a9c5d10aefc6236be3d746a16d152b194a86cff3aead853a35b395eR17-R24)
```diff
static TraceLogger()
{
- _logFileName = typeof(TraceLogger).Namespace + ".log";
-
- var textWriterTraceListener = new TextWriterTraceListener(_logFileName);
- Trace.Listeners.Add(textWriterTraceListener);
- Trace.AutoFlush = true;
+ try
+ {
+ _logFileName = (typeof(TraceLogger).Namespace ?? "WelsonJS") + ".log";
+ // Avoid adding duplicate listeners for the same file
+ foreach (TraceListener l in Trace.Listeners)
+ {
+ if (l is TextWriterTraceListener tw && string.Equals(tw.Writer?.ToString(), _logFileName))
+ {
+ Trace.AutoFlush = true;
+ return;
+ }
+ }
+ var textWriterTraceListener = new TextWriterTraceListener(_logFileName);
+ Trace.Listeners.Add(textWriterTraceListener);
+ Trace.AutoFlush = true;
+ }
+ catch
+ {
+ // Swallow to avoid failing app startup due to logging issues
+ }
}
```
Suggestion importance[1-10]: 7
__
Why: The suggestion correctly identifies that adding a trace listener in a static constructor can lead to duplicates and proposes a valid improvement to prevent this, enhancing the robustness of the logging initialization.

___
✅ Guard deserialization with null checks
**Add a null check on the deserialization result before using it to avoid possible NullReferenceException. Also validate that the stream is not null before constructing the reader.**
[WelsonJS.Toolkit/WelsonJS.Launcher/ResourceServer.cs [448-453]](https://github.com/gnh1201/welsonjs/pull/318/files#diff-818c326b0529d19f21de13c9a00464e3eaacb0de06acbbc0bcea444e1cd3bef8R448-R453)
```diff
using (var response = await _httpClient.GetStreamAsync(url))
-using (var reader = new StreamReader(response))
{
- var serializer = new XmlSerializer(typeof(BlobConfig));
- _blobConfig = (BlobConfig)serializer.Deserialize(reader);
+ if (response == null)
+ {
+ _logger?.Warn("Blob config response stream was null.");
+ return;
+ }
+ using (var reader = new StreamReader(response))
+ {
+ var serializer = new XmlSerializer(typeof(BlobConfig));
+ var deserialized = serializer.Deserialize(reader) as BlobConfig;
+ if (deserialized == null)
+ {
+ _logger?.Warn("Failed to deserialize BlobConfig (null result).");
+ return;
+ }
+ _blobConfig = deserialized;
+ }
}
```
Suggestion importance[1-10]: 6
__
Why:
Relevant best practice - Add null/undefined checks before accessing object properties or calling methods to prevent runtime exceptions.
