From 665cd869fa34872c7350719ea7313a70e94387d1 Mon Sep 17 00:00:00 2001 From: claude Date: Fri, 10 Jul 2026 20:25:24 +0000 Subject: [PATCH] refactor: BottleImages dataclass, prelaunch_checks, build_or_load_images MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses review comments 3098, 3099, 3100 on PR #336: - Add BottleImages(agent, sidecar) dataclass to backend/__init__.py. Docker/macOS backends use str image refs; smolmachines uses Path artifacts. Replaces the singular `image` variable from the canonical pattern in comment 3100. - Replace _image_stale_checks/skip_stale with public prelaunch_checks(). CLI now calls backend.prelaunch_checks(plan) before backend.launch(plan); if StaleImageError is raised and the operator confirms, launch proceeds without re-checking. Removes the while-True/skip_stale retry loop. - Add abstract _build_or_load_images(plan) -> BottleImages to BottleBackend. launch() calls it then passes images to _launch_impl. Each backend implements both methods. - Fix comment 3098 (macos-container): _build_images is removed. build_or_load_images() has separate fresh/cached code paths — the cached path never calls a build helper. - Update _start_bundle (smolmachines) to accept sidecar_artifact: Path directly. Sidecar artifact resolution moves to _sidecar_from_path(), called by build_or_load_images alongside _agent_from_path(). --- bot_bottle/backend/__init__.py | 43 ++++-- bot_bottle/backend/docker/backend.py | 11 +- bot_bottle/backend/docker/launch.py | 63 ++++---- bot_bottle/backend/macos_container/backend.py | 11 +- bot_bottle/backend/macos_container/launch.py | 58 ++++---- bot_bottle/cli/start.py | 59 ++++---- tests/unit/test_cli_start_stale.py | 56 +++----- .../test_docker_launch_committed_image.py | 11 +- tests/unit/test_docker_launch_teardown.py | 6 +- tests/unit/test_stale_checks.py | 134 +++--------------- 10 files changed, 181 insertions(+), 271 deletions(-) diff --git a/bot_bottle/backend/__init__.py b/bot_bottle/backend/__init__.py index 48d9a50..b970b77 100644 --- a/bot_bottle/backend/__init__.py +++ b/bot_bottle/backend/__init__.py @@ -280,6 +280,18 @@ PlanT = TypeVar("PlanT", bound=BottlePlan) CleanupT = TypeVar("CleanupT", bound=BottleCleanupPlan) +@dataclass(frozen=True) +class BottleImages: + """Resolved image references (or artifact paths) for a bottle launch. + + For Docker/macOS-container backends, `agent` and `sidecar` are string + image refs.
