From 705eb5a96948784ad72c58425a4719f4b1cd5e5d Mon Sep 17 00:00:00 2001 From: CleverAgents Automation Date: Wed, 15 Apr 2026 00:33:20 +0000 Subject: [PATCH 1/6] feat(plans): implement parallel subplan execution scheduler with max_parallel concurrency control - Add ParallelSubplanScheduler class for managing parallel subplan execution - Implement SubplanQueue for tracking pending, active, and completed subplans - Implement SchedulerState for immutable scheduler state tracking - Support configurable max_parallel concurrency limit (1-50) - Support sequential, parallel, and dependency-ordered execution modes - Automatic queuing of subplans when max_parallel limit is reached - Parent plan blocks until all subplans complete - Comprehensive failure handling and retry logic - Merge strategy selection for combining subplan outputs - Add comprehensive BDD test suite with 50+ scenarios - Test coverage for concurrency control, queue management, and state tracking ---

Remove duplicate @then decorator on step_verify_peak_concurrency_limit (caused AmbiguousStep error crashing all 8 unit test feature files) - Rename "the subplans should have been executed in order" to "the subplans should have been executed in sequential order" to avoid conflict with pre-existing step in subplan_execution_steps.py - Remove 13 additional @then step definitions that duplicated steps in subplan_execution_steps.py; alias context.exec_result and context.validation_error in @when steps so pre-existing steps work - Replace two # type: ignore comments (lines 438, 453) with typed Any variables per zero-tolerance policy - Apply ruff format to fix formatting (long import wrapping, list comps) - Add CHANGELOG entry and CONTRIBUTORS entry for #9555 ISSUES CLOSED: #9609 --- CHANGELOG.md | 1 + CONTRIBUTORS.md | 1 + features/parallel_subplan_scheduler.feature | 4 +- .../steps/parallel_subplan_scheduler_steps.py | 253 ++++++------------ 4 files changed, 88 insertions(+), 171 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index f1f295c80..0a30646ea 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -13,6 +13,7 @@ Changed `wf10_batch.robot` to be less likely to create files, and - **Virtual Resource Type Base Class** (#8610): Implemented `VirtualResource` base class with two example concrete implementations (`MetricResource`, `APIEndpointResource`) for abstract/computed resources that are derived rather than mapped to physical files. Virtual resources are computed on demand via a `compute_fn` callable. Includes Behave BDD scenarios in `features/resource_virtual_types.feature` exercising construction, computation, name validation, kwargs passthrough, exception handling, string representation, and subclassing. Resource names are validated against `^[a-zA-Z][a-zA-Z0-9_-]*$` (must start with a letter; alphanumeric, hyphens, and underscores otherwise). - **test(e2e): restore complete M2 acceptance test** (#11191): Restored the truncated M2 full actor compiler and LLM integration e2e acceptance test to its complete 10-step form. Added dynamic LLM provider selection via `Resolve LLM Actor` (falls back to Anthropic when OpenAI is unavailable or quota-exhausted), replacing hardcoded `gpt-4` / `openai/gpt-4` references in the actor config and action YAML. Added explicit return-code validation (`Should Be Equal As Integers ${r_actor.rc} 0`) for the actor registration step. - **docs(a2a): ACP to A2A migration guide** (#10230): Added migration guide documenting how to upgrade from the ACP module to the A2A module introduced in v3.6.0, including symbol renames, field renames, operation-name mappings, and YAML configuration updates. +- **feat(plans): parallel subplan execution scheduler** (#9555): Added `ParallelSubplanScheduler` with configurable `max_parallel` concurrency control, dependency-ordered execution (`SEQUENTIAL`, `PARALLEL`, `DEPENDENCY_ORDERED` modes), fail-fast mode, per-subplan timeout enforcement, retry support, and pluggable merge strategies. The scheduler delegates execution to `SubplanExecutionService` and exposes `schedule()`, `get_queue_status()`, `get_available_slots()`, and `can_accept_more()` APIs. Includes comprehensive BDD test coverage in `features/parallel_subplan_scheduler.feature`. - **Plan Prompt JSON Timing Field** (#9353): `agents plan prompt --format json` now includes `timing.started` as an ISO 8601 UTC timestamp in the JSON envelope, matching the spec (§CLI Commands — `agents plan prompt`).

The scheduler test fixtures constructed SubplanStatus instances with short logical IDs ("subplan-001", "subplan-A") which failed validation at fixture-construction time, erroring 22 of 38 originally-failing scenarios in unit_tests CI before the behavioural assertions could even run. Derive a deterministic 26-char Crockford-Base32 ID from each logical name via SHA-256 and translate fail-id sets, block-second dicts, dependency graphs, and result-status lookups through the same helper so cross-references stay consistent. Also add the missing step definitions unique to the parallel_subplan_scheduler scenarios (staggered-completion fixture, retry-then-succeed fixture, fail_fast- disabled scheduler, mode-only scheduler, timeout-errored verifier) and remove duplicate @then registrations that conflict with shared step definitions in subplan_execution_steps.py.
