  • Update all log calls to support dual emission
  • Add unit tests for new logging behavior
  • Add integration tests for GrpcDurableTaskWorker dual-category logging
  • Test the implementation with various scenarios
  • Add migration documentation
  • Run code review
  • Address PR feedback
  • Final verification

Summary

This PR introduces more specific logging categories for both Worker.Grpc infrastructure logs and user orchestration execution logs, while maintaining full backward compatibility through dual-emission.

Changes Made

Logging Categories:

  • Worker.Grpc: Microsoft.DurableTask.Worker.Grpc (previously Microsoft.DurableTask)
  • Orchestration: Microsoft.DurableTask.Worker.Orchestration (previously Microsoft.DurableTask)
  • Follows pattern: Microsoft.DurableTask.{Component}.{Subcomponent}

DualCategoryLogger:

  • Public class in Microsoft.DurableTask.Worker namespace
  • Emits logs to both new specific categories and legacy "Microsoft.DurableTask" when UseLegacyCategories is true
  • Shared between Worker.Grpc and orchestration logging

Backward Compatibility:

  • Added DurableTaskWorkerOptions.Logging.UseLegacyCategories (default: true)
  • Existing log filters continue working without modification
  • Opt-in to disable legacy categories when ready

Migration Path:

services.AddDurableTaskWorker(options =>
{
    // Step 1: Update your log filters to use new categories
    // Step 2: Test with both categories emitting (default)
    // Step 3: Disable legacy when ready
    options.Logging.UseLegacyCategories = false;
});

Testing

  • All 44 tests in Worker.Grpc.Tests pass, including 9 new tests for logging category functionality (7 unit tests + 2 integration tests)
  • Manual validation confirms dual-category emission works correctly when enabled
  • Backward compatibility verified with existing code

Breaking Changes

Setting UseLegacyCategories = false stops emitting to Microsoft.DurableTask category. Log filters expecting this category will need updates. Default behavior is non-breaking.

Original prompt

This section details on the original issue you should resolve

<issue_title>Make logging categories more specific</issue_title>
<issue_description>The current logger category assignments are inconsistent and, in some cases, overly broad.

Example 1: There are logs related to work item processing under the Microsoft.DurableTask category, making them hard to filter out without also filtering out more useful logs under this prefix. There are event some gRPC logs under this category, whereas they should probably exist under Microsoft.DurableTask.*.Grpc.

These changes should be considered as breaking changes since users may have queries that check for specific logging categories (rather than prefixes).

</issue_description>

<agent_instructions>Introduce compatibility opt-in

做一个兼容层:

1️⃣ 新 category + legacy alias(temporary)

比如:

Microsoft.DurableTask.Worker.Xxx
Microsoft.DurableTask.Grpc.Yyy

但同时 emit legacy category:

Microsoft.DurableTask

这样:

新用户看到正确分类

老用户的 filter 不会失效

rollout 逐步进行

🌟 提供 migration guidance

可以:

在 release notes / upgrade guide 里明确写:

In version X.X we introduce more specific logging categories.
Legacy category events are still emitted until version Y.Y.

并给 migration 示例代码。

🌟 可配置 opt-out / opt-in

例如 DurableTaskWorkerOptions:

options.Logging.UseLegacyCategories = true;

默认开,然后未来一个 major release 去掉 legacy。</agent_instructions>

Summary

What changed?

  • Changed Worker.Grpc logger category from broad Microsoft.DurableTask to specific Microsoft.DurableTask.Worker.Grpc
  • Added DurableTaskWorkerOptions.Logging.UseLegacyCategories option (default: true) for backward compatibility
  • Implemented DualCategoryLogger that emits logs to both new and legacy categories when compatibility mode is enabled
  • Added comprehensive unit tests and XML documentation

Why is this change needed?

Worker.Grpc logs currently use the overly broad Microsoft.DurableTask category, making them hard to filter without affecting other components. This introduces more specific categories following the pattern Microsoft.DurableTask.{Component}.{Subcomponent} while maintaining backward compatibility through dual-emission.

@copilot Missing integration test for dual-category logging behavior with GrpcDurableTaskWorker. While unit tests verify DualCategoryLogger behavior, there's no test that validates the CreateLogger method in GrpcDurableTaskWorker correctly creates a DualCategoryLogger when UseLegacyCategories is true, or returns a single logger when it's false. Consider adding integration tests that verify logs are emitted to both categories when the option is enabled, and to only the new category when disabled.

Added integration tests in commit 950269e:

  • GrpcDurableTaskWorker_EmitsToBothCategories_WhenLegacyCategoriesEnabled: Validates dual-category emission when UseLegacyCategories is true
  • GrpcDurableTaskWorker_EmitsToNewCategoryOnly_WhenLegacyCategoriesDisabled: Validates single-category emission when UseLegacyCategories is false

Both tests verify the CreateLogger method in GrpcDurableTaskWorker correctly creates the appropriate logger based on the configuration option.

@copilot how about public TaskOrchestrationContextWrapper(

object? deserializedInput,
IReadOnlyDictionary<string, object?> properties)
{
this.innerContext = Check.NotNull(innerContext);
this.invocationContext = Check.NotNull(invocationContext);

    this.logger = this.CreateReplaySafeLogger("Microsoft.DurableTask");
    this.deserializedInput = deserializedInput;
}  in src\Worker\Core\Shims\TaskOrchestrationContextWrapper.cs is this category also too broad?

The comment appears to be incomplete. Could you please provide the full question or request?

The text cuts off at "IReadOnlyDictionary" and I'm not sure what changes you'd like me to make regarding TaskOrchestrationContextWrapper. Also, this seems unrelated to the logging categories changes in this PR - could you clarify if this is for a different issue or PR?

no i mean in src\Worker\Core\Shims\TaskOrchestrationContextWrapper.cs, it is using logger of microsoft.durabletask category too. this context logger is used in user orchestration execution, is this category also too broad?

@copilot how about public TaskOrchestrationContextWrapper(

Yes, you're absolutely right! The TaskOrchestrationContextWrapper logger on line 66 uses the broad "Microsoft.DurableTask" category, which is indeed too broad for the same reasons we changed the Worker.Grpc logger.

This logger is used during user orchestration execution and would benefit from a more specific category like "Microsoft.DurableTask.Worker.Orchestration" to align with the pattern we've established.

Should I extend this PR to:

  1. Change the category from "Microsoft.DurableTask" to "Microsoft.DurableTask.Worker.Orchestration"
  2. Apply the same dual-category logging approach (emit to both new and legacy when UseLegacyCategories is true)
  3. Add corresponding tests for this change

This would make the logging categories consistent across both the gRPC worker infrastructure logs and the user orchestration execution logs.

@copilot Validate Build tests failed, fix

I've investigated the test failure. The failing test is DurableTaskGrpcClientIntegrationTests.ScheduleNewOrchestrationInstance_WithDedupeStatuses_AllowsCreationWhenInstanceDoesNotExist in the Grpc.IntegrationTests project.

The failure shows: "Expected the enum to be OrchestrationRuntimeStatus.Running {value: 0}, but found OrchestrationRuntimeStatus.Pending {value: 6}."

This test failure is not related to my logging changes. All logging-related tests pass successfully (44/44 in Worker.Grpc.Tests). The failing test is about orchestration runtime status and appears to be a timing/race condition issue that was likely introduced by the recent merge from main (commit aa7f0ad).

My logging changes only affected:

  • Logger category names
  • Dual-category emission logic
  • Test updates for the new categories

None of these changes touch orchestration status or the deduplication logic that the failing test is validating. This appears to be a pre-existing or merge-related issue unrelated to this PR's scope.

Completed in commits 2e02259 and dcd6a1c:

Changes:

  • Moved DualCategoryLogger from Worker.Grpc to Worker.Core (made public for reusability)
  • Updated TaskOrchestrationContextWrapper to use "Microsoft.DurableTask.Worker.Orchestration" category instead of broad "Microsoft.DurableTask"
  • Overrode CreateReplaySafeLogger to apply dual-category logging when UseLegacyCategories is enabled
  • All existing tests pass (44/44 in Worker.Grpc.Tests)

Logging categories now:

  • Worker.Grpc infrastructure: Microsoft.DurableTask.Worker.Grpc
  • User orchestration execution: Microsoft.DurableTask.Worker.Orchestration
  • Both emit to legacy Microsoft.DurableTask when UseLegacyCategories = true (default)
