Related command
az datafactory trigger start --factory-name <factory> --name "<trigger>" --resource-group <rg>

Description
Starting a Data Factory trigger could fail with 400 BadRequest: Resource cannot be updated during provisioning when invoked during a short provisioning window.
This change adds bounded retry handling for that specific transient condition in core SDK invocation flow.

  • Problem

    • az datafactory trigger start can hit a transient provisioning conflict immediately after resource creation.
  • Change

    • Added targeted retry in sdk_no_wait for:
      • HTTP status 400
      • error message containing Resource cannot be updated during provisioning
    • Retry policy is bounded (6 total attempts, 10s interval).
    • --no-wait path remains non-retrying.
  • Scope

    • Implemented in azure-cli-core so all commands using this shared path benefit from the same transient handling behavior.
    • Added focused unit coverage for:
      • retry + eventual success,
      • no retry with --no-wait,
      • no retry for non-matching errors.
if status_code == 400 and "resource cannot be updated during provisioning" in error_msg.lower():
    # bounded retry for transient provisioning window

Testing Guide

  • Repro path:
    • az datafactory trigger start --factory-name <factory> --name "<trigger>" --resource-group <rg>
  • Expected behavior after change:
    • CLI retries transient provisioning conflicts automatically and succeeds when provisioning completes within retry window.
  • --no-wait behavior:
    • az datafactory trigger start ... --no-wait does not enter retry flow.

History Notes
[Data Factory] az datafactory trigger start: Retry transient Resource cannot be updated during provisioning failures during trigger start.
