Now: ruff check . -> All checks passed. Highlights: - F823 (REAL BUG) backend/services/netmiko_client.py: a redundant local 'import re' inside pull_running_config made 're' function-local, so the re.search() call above it raised UnboundLocalError. Removed the local import. - E741 x5, F841 x3, SIM105 x8, SIM108 x2, E701 x2, B007, F401, F404, I001, UP006/035/037/041/045, F541, E402, B024: applied safe autofixes and hand edits. B008 (47x) is added to ignore: FastAPI requires Depends()/File()/ Query() in argument defaults -- that is the documented DI idiom, not a bug. - security_auditor._check_aaa_config: extracted the tangled inline conditional into a named variable. Behaviour verified unchanged by direct test: reports the missing-local-fallback finding only when 'aaa authentication login' is present without 'local' (1 for the bad case, 0 for the good case). - B024: SerialConnection is a runtime-selected marker base, so an explicit noqa with rationale rather than adding a wrong @abstractmethod. Verified: ruff clean; 11 tests pass; import main -> 67 routes; whole tree compiles; gitleaks clean. --- backend/config.py | 8 +- backend/database.py | 6 +- backend/main.py | 20 ++- backend/models/__init__.py | 5 +- backend/routers/chat.py | 7 +- backend/routers/config_parser_router.py | 27 ++-- backend/routers/configs.py | 12 +- backend/routers/containerlab.py | 14 +- backend/routers/dashboard.py | 11 +- backend/routers/discovery.py | 3 +- backend/routers/security.py | 17 +-- backend/routers/switches.py | 24 +-- backend/routers/templates.py | 31 ++-- backend/routers/workflows.py | 7 +- backend/schemas.py | 178 +++++++++++------------ backend/services/config_parser.py | 9 +- backend/services/connection.py | 39 +++-- backend/services/containerlab_service.py | 16 +- backend/services/deployer.py | 18 +-- backend/services/nethermind_agent.py | 19 ++- backend/services/netmiko_client.py | 11 +- backend/services/security_auditor.py | 17 +-- backend/services/serial_client.py | 11 +- backend/services/switch_config_model.py | 29 ++-- backend/services/template_engine.py | 17 +-- backend/services/workflow_engine.py | 9 +- pyproject.toml | 7 +- scripts/cli.py | 17 +-- scripts/nethermind.py | 14 +- tests/mock_switch.py | 10 +- 30 files changed, 294 insertions(+), 319 deletions(-) diff --git a/backend/config.py b/backend/config.py index 557073e..49c1d9e 100644 --- a/backend/config.py +++ b/backend/config.py @@ -2,9 +2,8 @@ Loads settings from environment variables (via .env file or system env).
