+    /// <param name="exception">An optional <see cref="Exception"/> that was thrown within the outgoing HTTP request processing.</param>
+    // TODO: adding a new parameter to the interface method is a breaking change. Pay additional attention to this during review.
+    // Alternatively, we can decide to add another overload instead.
+    void Enrich(IEnrichmentPropertyBag enrichmentBag, HttpRequestMessage request, HttpResponseMessage? response = null, Exception? exception = null);


We need to discuss this one

Is it breaking if it's defaulted to null?

No, the breaking change here is that I added Exception? exception - which means that existing users of this API would need to add the new parameter into their implementation of the interface

+            }
+
+            // Recommendation is to swallow the exception (logger shouldn't throw), so we don't re-throw here:
+            return null;


As @CarnaViire pointed, a logger shouldn't re-throw (but it will change our current behavior)

xakep139 · 2023-07-28T15:47:05Z

src/Libraries/Microsoft.Extensions.Http.Telemetry/Logging/Internal/HttpClientLogger.cs

+
+    public object? LogRequestStart(HttpRequestMessage request)
+    {
+        throw new NotSupportedException();


As of now the best we can offer for sync overloads - is to call their async counterparts with .GetAwaiter().GetResult(), that's because there's no sync API of reading request/response message body

+            }
+
+            propertyBag = LogMethodHelper.GetHelper();
+            FillLogRecord(logRecord, propertyBag, in elapsed, request, response, exception);


We don't use TimeProvider here since elapsed is provided out-of-the-box, but we can consider ignoring it and using the old logic

xakep139 · 2023-07-28T15:49:26Z

src/Libraries/Microsoft.Extensions.Http.Telemetry/Logging/Internal/Log.cs

+        var httpMethod = request[startIndex].Value;
+        var httpHost = request[startIndex + 1].Value;
+        var httpPath = request[startIndex + 2].Value;
+        return FormattableString.Invariant($"{httpMethod} {httpHost}/{httpPath}");


This is to align with current behavior in internal library

test/Libraries/Microsoft.Extensions.Http.Telemetry.Tests/Logging/Internal/TestLoggingHandler.cs

+
+    private static DelegatingHandler CreateInternalBclLoggingHandler(IHttpClientLogger logger, HttpMessageHandler? innerHandler)
+    {
+        var handlerType = typeof(IHttpClientFactory).Assembly.GetType("Microsoft.Extensions.Http.Logging.HttpClientLoggerHandler");


This was taken from Natalia's PoC branch main...CarnaViire:extensions:poc-hcf-custom-logging

Are you sure you need this? The intent on my side was just to show that our HttpClientLoggerHandler passes all the tests you had for your logging handler. Like, "you can trust our handler" 😄

So I believe the set of tests that were verifying the handler itself can be removed from dotnet/extensions repo (I haven't looked at the PR yet, I don't know how exactly you've transformed the test cases).

Or if you do need a handler for some other tests, create it "normal way" via IHttpMessageHandlerFactory.

Please re-target to release/8.0, if this is necessary for .NET 8.

xakep139 · 2023-08-16T08:55:46Z

Please re-target to release/8.0, if this is necessary for .NET 8.

I would rather merge it to main first, and then cherry-pick the commit into release/8.0.
Right now, if I target release/8.0, the PR brings a few unrelated changes from main, e.g. .github/fabricbot.json, etc.
