* feat(workflows): Make telemetry opt-in via WithOpenTelemetry()
- Add WorkflowTelemetryOptions class with EnableSensitiveData property
- Add WorkflowTelemetryContext to manage ActivitySource lifecycle
- Add WithOpenTelemetry() extension method on WorkflowBuilder
- Update all workflow components to use telemetry context:
- WorkflowBuilder, Workflow, Executor
- InProcessRunnerContext, InProcessRunner
- LockstepRunEventStream, StreamingRunEventStream
- All edge runners (Direct, FanIn, FanOut, Response)
- Telemetry is now disabled by default
- Users must call WithOpenTelemetry() to enable spans/activities
BREAKING CHANGE: Workflow telemetry is now opt-in. Users who relied on
automatic telemetry must add .WithOpenTelemetry() to their workflow builder.
* refactor: Pass telemetry context as parameter instead of via interface
- Remove IWorkflowContextWithTelemetry interface
- Add internal ExecuteAsync overload that accepts WorkflowTelemetryContext
- Public ExecuteAsync delegates with WorkflowTelemetryContext.Disabled
- InProcessRunner passes TelemetryContext when calling ExecuteAsync
- BoundContext now implements IWorkflowContext (not the removed interface)
* Add optional ActivitySource parameter to WithOpenTelemetry
Allow users to provide their own ActivitySource when enabling telemetry,
giving them better control over the ActivitySource lifecycle. When not
provided, the framework creates one internally (existing behavior).
Changes:
- Add optional activitySource parameter to WithOpenTelemetry() extension
- Update WorkflowTelemetryContext to accept external ActivitySource
- Add unit test for user-provided ActivitySource scenario
* Add component-level telemetry control with disable flags
Allow users to selectively disable specific activity types via
WorkflowTelemetryOptions. All activities are enabled by default.
New disable flags:
- DisableWorkflowBuild: Disables workflow.build activities
- DisableWorkflowRun: Disables workflow_invoke activities
- DisableExecutorProcess: Disables executor.process activities
- DisableEdgeGroupProcess: Disables edge_group.process activities
- DisableMessageSend: Disables message.send activities
Added helper methods to WorkflowTelemetryContext for each activity type
and updated all activity creation sites to use them.
* Implement EnableSensitiveData to log executor input/output
When EnableSensitiveData is true in WorkflowTelemetryOptions, executor
input and output are logged as JSON-serialized attributes in the
executor.process activity.
New activity tags:
- executor.input: JSON serialized input message
- executor.output: JSON serialized output result (non-void only)
Added suppression attributes for AOT/trimming warnings since this is
an opt-in feature for debugging/diagnostics.
* Refactor activity start methods to centralize tagging logic
Move tagging logic into WorkflowTelemetryContext methods:
- StartExecutorProcessActivity now accepts executorId, executorType,
messageType, and message; sets all tags including executor.input
when EnableSensitiveData is true
- Added SetExecutorOutput method to set executor.output after execution
- StartMessageSendActivity now accepts sourceId, targetId, and message;
sets all tags including message.content when EnableSensitiveData is true
Simplified Executor.cs and InProcessRunnerContext.cs by removing
inline tagging code. Added message.content tag constant.
* Revert Python changes
* Update samples and code cleanup
* Fix file formatting
* Add comment
* Add telemetry configuration to declarative workflow
* Remove delays in tests
* Address comments
* feat: Add support for Workflow-as-Executor
* Fixes routing of 'object' compile-typed variables to properly take in type information
* Fixes a concurrency issue in StepTracer
* fix: Make Subworkflow ExternalRequests work properly
* fix: Threading and Concurrency fixes; prep for OffThread Mode
* refactor: Remove dead code around OffStreamRunEventStream
Currently not used, and will be replaced with a rewrite when brought back, so having it in the change is not valuable.
* ci: Work around issues with dotnet-format not properly analyzing the source
* fix: Fix the logic of AsyncCoordinator and AsyncBarrier
* Prevent individual wait cancellations from canceling the entire barrier
* Propagate information about whether the wait was completed or cancelled, and whether any waiters were present when released
* fix: Remove superfluous acces to .Keys in InProcStepTracer
* refactor: Clean up AsyncCoordinator's use of AsyncBarrier
