Head commit for run: 188bb01c8a91f88085b3dfa7fb3aceeaf89da35a / 1fanwang <[email protected]> AIP-97: Disruption Readiness: classify why a task failed and refund infra retries (no DB) Pillar 1: add a `failure_kind` argument (infra / application / timeout / manual) and a transient `reason` token to the `on_task_instance_failed` listener hook. The worker sets application or timeout for the failures it catches; the scheduler sets infra for a task killed from outside. The Kubernetes executor classifies a failed pod (Evicted / preempted is infra; an app crash or an OOMKill against the container's own limit is application). pluggy dispatches by name, so a listener that does not declare the arguments is unchanged. Pillar 2: a failure classified as infra gives back the retry it used (reuses `max_tries`, bounded by `[core] max_infra_refunds`), so infra churn does not spend a task's `retries`. Opt-in via `[core] infra_failure_refund_retries`, off by default. This holds even at `retries=0`: `is_eligible_to_retry` now gates on `max_tries` (the retry ceiling the refund bumps), matching the execution API's `_is_eligible_to_retry`, rather than short-circuiting on the user's `retries`. The two retry-decision paths no longer disagree, and no per-task counter or column is needed. No schema change: the reason is handed to the listener at failure time rather than persisted, so this backports cleanly to older release branches with no upgrade or rollback step. How the reason token best reaches the listener (this transient `reason` argument, or folding it into the existing `error` argument) is AIP-97 open question 3.
