- Retry GitHub pyproject version fetch up to 3 times on failure
- Fall back to Comfy Registry install endpoint when GitHub is unavailable
- Avoid caching failed version checks, so stale unavailable states do not persist
- Add targeted tests for registry fallback and failed-check caching behavior
Replace the 1095-line monolithic SearchService with a thin facade that
delegates to SearchOrchestrator. Split the implementation into three
focused modules:
- search_orchestrator.py: request parsing, provider coordination, and
response construction
- search_providers.py: per-source execution, progress callbacks, and
async task creation
- search_cache.py: timestamping and stable cache stamping for results
Add unit tests for the new components in
tests/test_search_service_components.py. Preserve the existing HTTP
route behavior by keeping SearchService.search_sources as the stable
route-facing API.
Replace dynamic MODEL_SERVICE_DEPENDENCIES injection with frozen dataclasses
(CivitAISearchDependencies, CustomUrlDependencies, ModelDetailsDependencies)
to make service dependencies explicit and type-safe. Update model services to
construct via RouteContext, and add tests enforcing minimal dataclass fields.
Break down the monolithic model_service into smaller, single-responsibility
services: CivitAISearchService, CustomUrlService, and ModelDetailsService.
Introduce ModelServiceDependencies base class to centralize RouteContext
dependency injection. Update model_service to act as a thin facade that
delegates to the specialized services. Add unit tests validating the new
service boundaries and basic request validation behavior.
Break monolithic model_info, search, and workflow route files into
smaller modules by responsibility: civitai_search, custom_url,
model_details, search_support, source_search, workflow_analysis,
hashes, and loaded_models. Update registry imports to preserve the
existing route registrations and API surface. Add partition coverage
tests to ensure no route endpoints are dropped or duplicated.
Move the inline route definitions out of __init__.py into a new core/routes
package (registry, base_models, helpers, settings, version). Add the
JobProgressTracker utility in core/progress.py and extract version discovery
logic into core/version.py. Update tests to cover the refactored structure.
Implement streaming SHA-256 verification for Python download backend,
writing to a .part file first and publishing to the final path only after
the hash matches the source metadata. Mismatched downloads are preserved
at .badsha instead of being silently deleted. Close the download response
in a finally block to avoid leaking handles on cancellation or errors.
