📝 WalkthroughWalkthroughThe change adds Event Ledger publishing for function status transitions. A shared service persists changed statuses and publishes structured CloudEvents synchronously.

In
`@src/control-plane-services/cloud-functions/nvcf-core/src/main/java/com/nvidia/nvcf/service/eventledger/EventLedgerClient.java`:
- Line 176: In the event construction around transition.deploymentId(), rename
only the top-level CloudEvents extension attribute deploymentId to an
all-lowercase valid attribute name; keep the data.deploymentId field unchanged.
- Around line 155-160: Update EventLedgerClient to define dedicated counters for
queue rejection, enqueue failure, and publication failure, then increment each
counter in the corresponding suppressed catch paths in publish and send,
including RejectedExecutionException, enqueue RuntimeException, serialization,
and HTTP failures. Preserve the existing logging and event flow.
- Line 213: Update EventLedgerClient.close() to call executor.shutdown() first
and await termination for a bounded period compatible with
spring.lifecycle.timeout-per-shutdown-phase, falling back to
executor.shutdownNow() if tasks do not finish. Catch InterruptedException from
awaitTermination(), restore the thread’s interrupt status, and then perform the
forced shutdown fallback.
In
`@src/control-plane-services/cloud-functions/nvcf-service/src/main/resources/application.yaml`:
- Around line 114-115: Update the event-ledger token-uri configuration to keep
the localhost HTTP endpoint limited to local development and use an HTTPS issuer
override for every non-local deployment where Event Ledger is enabled. Preserve
the existing Spring OAuth issuer-based resolution while ensuring non-local
client credentials are sent only over TLS.
