From cc209eca5209812d8782505d929df80a39de6428 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Thu, 16 Apr 2026 09:29:16 +0000 Subject: [PATCH 1/7] feat: implement timer origins for CreateTimerAction and TimerCreatedEvent Add timer origin protobuf messages (TimerOriginCreateTimer, TimerOriginExternalEvent, TimerOriginActivityRetry, TimerOriginChildWorkflowRetry) and origin oneof fields to CreateTimerAction and TimerCreatedEvent. Implement origin assignment in WorkflowOrchestrationContext: - CreateTimer sets TimerOriginCreateTimer - WaitForExternalEvent sets TimerOriginExternalEvent (with sentinel for indefinite waits) - Activity retry timers set TimerOriginActivityRetry with stable taskExecutionId - Child workflow retry timers set TimerOriginChildWorkflowRetry with first-child instanceId Add drop-and-shift replay tolerance for optional external event timers when replaying pre-patch histories that lack the synthetic timer. Implements dapr/dotnet-sdk#1787 Agent-Logs-Url: https://github.com/dapr/dotnet-sdk/sessions/d91a8228-5499-4c7f-bf21-c9bd4fd6147a Co-authored-by: WhitWaldo <2238529+WhitWaldo@users.noreply.github.com> --- .../orchestrator_service.proto | 35 ++ src/Dapr.Workflow/Client/RetryInterceptor.cs | 20 +- .../Internal/WorkflowOrchestrationContext.cs | 339 +++++++++++++++++- 3 files changed, 379 insertions(+), 15 deletions(-) diff --git a/src/Dapr.Workflow.Grpc/orchestrator_service.proto b/src/Dapr.Workflow.Grpc/orchestrator_service.proto index f6d08e5e2..1cbde9cdd 100644 --- a/src/Dapr.Workflow.Grpc/orchestrator_service.proto +++ b/src/Dapr.Workflow.Grpc/orchestrator_service.proto @@ -167,6 +167,14 @@ message TimerCreatedEvent { // If defined, indicates that this task was the starting point of a new // workflow execution as the result of a rerun operation. optional RerunParentInstanceInfo rerunParentInstanceInfo = 3;

CreateTimer completes after timer fires 2. WaitForExternalEvent with finite timeout completes when event arrives 3. WaitForExternalEvent with finite timeout returns timed-out when no event 4. WaitForExternalEvent indefinite completes when event arrives All tests use [MinimumDaprRuntimeFact("1.18")] to skip on older runtimes.
