From bec78286f62a6c0629217ff2ca142df030de30e7 Mon Sep 17 00:00:00 2001 From: James Wiesebron Date: Wed, 29 Apr 2026 10:25:40 -0700 Subject: [PATCH 1/4] Fix #2245: rebaseline post-consensus-timeout budget on producer progress MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The hardcoded `post_timeout_budget = 3600` in `_run_concurrent_phase` counted iteration time against a single fixed bucket, so a healthy multi-iteration BRC consensus cycle (NACK → repropose → re-review) could be force-killed mid-iteration even when reviewers were actively producing useful feedback. Replace it with a per-iteration clock that rebaselines on producer progress: each fresh CONSENSUS_PROPOSE (initial or NACK→re-propose) resets the iteration budget so the next round of reviews gets a clean clock instead of inheriting the prior round's wall-clock spend. An absolute cap (`post_consensus_max_total_seconds`, default 4h) bounds the total wait so unbounded propose churn can't stall the pipeline. Both budgets are exposed on `PipelineConfig` for per-deployment tuning. Defaults (3600s per-iteration / 14400s absolute) preserve the prior force-kill point for the no-progress case. --- orchestrator/models.py | 24 ++ orchestrator/routes/pipelines.py | 93 +++- orchestrator/tests/test_consensus_polling.py | 17 +- .../tests/test_post_timeout_rebaseline.py | 404 ++++++++++++++++++ 4 files changed, 527 insertions(+), 11 deletions(-) create mode 100644 orchestrator/tests/test_post_timeout_rebaseline.py diff --git a/orchestrator/models.py b/orchestrator/models.py index 1fba8ed297..0a79f1347c 100644 --- a/orchestrator/models.py +++ b/orchestrator/models.py @@ -377,6 +377,30 @@ class PipelineConfig(BaseModel): consensus_timeout_minutes: int = Field( default=30, ge=1, description="Timeout for consensus before HITL escalation" ) + post_consensus_iteration_budget_seconds: int = Field( + default=3600, + ge=60, + description=( + "After consensus_timeout_minutes elapses, the post-timeout poll loop " + "waits up to this many seconds without producer progress before " + "force-killing remaining containers (issue #2245).

The `get_peer_consensus_tracker(pipeline_id, slice_id=None)` signature cannot raise `TypeError` for a positional `slice_id`; the fallback was speculative and unreachable. - Read the new post-consensus knobs directly off `PipelineConfig` instead of `getattr(..., default)`. Pydantic provides defaults; the `getattr` defaults silently masked any future field rename. - Add a cross-field validator on `PipelineConfig` that rejects `post_consensus_max_total_seconds < post_consensus_iteration_budget_seconds`. Without it, a misconfigured pipeline silently makes the per-iteration rebaseline logic unreachable (the absolute cap fires first every time). - Replace the `__dict__` fallback in the test helper with `PipelineConfig(**overrides)` — the fallback was dead code and would have bypassed Pydantic validation if it ever fired. - Tighten the post-timeout-snapshot comment: the safety against `datetime > None` comes from the `is None` short-circuit at the rebaseline check, not from any datetime/None ordering. - Add tests for the new cross-field validator (rejects mismatched budgets, accepts equal budgets). --- orchestrator/models.py | 17 ++++++++ orchestrator/routes/pipelines.py | 24 ++++------- .../tests/test_post_timeout_rebaseline.py | 42 +++++++++++++++---- 3 files changed, 59 insertions(+), 24 deletions(-) diff --git a/orchestrator/models.py b/orchestrator/models.py index 0a79f1347c..b7f40de438 100644 --- a/orchestrator/models.py +++ b/orchestrator/models.py @@ -620,6 +620,23 @@ class PipelineConfig(BaseModel): ), ) + @model_validator(mode="after") + def _validate_post_consensus_budgets(self) -> "PipelineConfig": + """Reject configs where the absolute cap is below the per-iteration budget. + + Without this, a misconfigured pipeline (e.g. ``iteration_budget=7200`` + with ``max_total=3600``) silently makes the per-iteration logic + unreachable — the absolute cap would always fire first.
