The command restores a plan's sandbox to the state captured at a given checkpoint, discarding all decisions made after that checkpoint. The checkpoint can be specified as an optional positional second argument or via the `--to-checkpoint` named option. Supports `--yes/-y` flag to skip confirmation prompts and `--format/-f` for output format selection (rich/plain/json/yaml). Included with comprehensive BDD test coverage (>= 97%) and spec-aligned output formatting showing rollback summary, changes reverted, impact analysis, and post-rollback state panels. ### Fixed +- **TUI ActorSelectionOverlay render method rename** (#11039): Renamed `ActorSelectionOverlay._render()` to `_refresh_display()` to avoid shadowing the Textual Widget's internal `_render` method. The overlay class inherits from `textual.widgets.Static`, which has its own `_render` implementation used for rendering widget content. Shadowing this caused incorrect repaint behavior and interfered with Textual's layout pass. - **Guard cleanup_stale against execute/processing and execute/complete plans** (#11121): ``_create_sandbox_for_plan()`` in ``src/cleveragents/cli/commands/plan.py`` now skips ``GitWorktreeSandbox.cleanup_stale()`` when the plan is in diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index 59a6ba5bf..6aebe58b6 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -43,3 +43,4 @@ Below are some of the specific details of various contributions. * HAL 9000 has contributed the agents plan rollback command (PR #8674 / issue #8557): implemented checkpoint-based plan state restoration with the `agents plan rollback []` CLI command as part of Epic #8493, enabling plans to be restored to previous checkpoints, discarding post-checkpoint decisions, and resuming execution from the rolled-back state. Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality. * HAL 9000 has contributed the PyYAML security upgrade (PR #11012 / issue #9055): added `pyyaml>=6.0.3` dependency constraint to address known YAML parsing vulnerabilities. * HAL 9000 has contributed the A2A module rename standardization BDD tests (PR #10583 / issue #8615): comprehensive Behave test suite validating that all 22 A2A symbols are properly exported from `cleveragents.a2a`, no legacy ACP references remain in the module source, and documentation uses correct A2A naming conventions — fixing inline imports, unused behave symbols, cross-scenario context dependencies, and missing type annotations. +* HAL 9000 has contributed rename of `ActorSelectionOverlay._render` to `_refresh_display` to avoid shadowing Textual Widget internal method (PR #11042). diff --git a/features/steps/tdd_actor_selection_render_rename_steps.py b/features/steps/tdd_actor_selection_render_rename_steps.py new file mode 100644 index 000000000..08e451024 --- /dev/null +++ b/features/steps/tdd_actor_selection_render_rename_steps.py @@ -0,0 +1,141 @@ +"""Step definitions for tdd_actor_selection_render_rename.feature. + +Regression guard for issue #11039: verifying that ActorSelectionOverlay +does not shadow Textual Widget's internal _render method via the renamed +_refresh_display() implementation. +""" +from __future__ import annotations + +import sys +from types import ModuleType +from unittest.mock import MagicMock, PropertyMock, patch + +from behave import and_, given, then, when + + +# --------------------------------------------------------------------------- +# Shared mock-Textual infrastructure with REAL Textual Static signature +# --------------------------------------------------------------------------- + + +def _ensure_mock_installed(context: object) -> None: + """Install mocked Textual modules on sys.modules if not already done.""" + if getattr(context, "_tui_static_mock_ready", False): + return + + # Build mock modules mimicking textual.widgets.Static including its _render() + mock_textual = ModuleType("textual") + mock_app = ModuleType("textual.app") + mock_widgets = ModuleType("textual.widgets") + mock_containers = ModuleType("textual.containers") + + class TextualStatic: + """Real signature of textual.widgets.Static — has both _render AND update.""" + + def __init__(self, text: str = "", *args: object, **kwargs: object) -> None: + self._text = text + + def _render(self) -> str | None: + """The actual Textual Static._render that returns rendered content. + + The original bug was that ActorSelectionOverlay defined its own + ``_render()``, shadowing this method.
