What was changed
Worker heartbeats now include an
EnvironmentInfomessage describing the JVM version, detected hosting environments (Docker, Kubernetes, AWS Lambda/ECS, Google Cloud Run/App Engine, Azure App Service/Functions/Container Apps), and the OS platform (Linux/macOS/Windows version, architecture, and Windows CRT).The information is attached to each worker's heartbeats until the server accepts one, then omitted.
HeartbeatManagertracks pending workers and clears them only after a successfulrecordWorkerHeartbeat.A new experimental
WorkflowClientOptions.Builder#setDisableWorkerEnvironmentInfoturns the reporting off.Why?
Port of Core's temporalio/sdk-rust#1457 so all SDKs report the same analytical information about the environments they run in.
Checklist
Closes N/A
How was this tested:
New unit tests in
WorkerEnvironmentInfoTestcover live detection, hosting-environment env vars, cgroup parsing, and Java version parsing.HeartbeatManagerTestgained cases for retry-until-accepted delivery and for omitting the environment when disabled.No.
