From 638fc4c09ad2910875eabec5c73998b6c728e964 Mon Sep 17 00:00:00 2001 From: Alexander Zaikman Date: Fri, 4 Sep 2026 00:05:50 +0300 Subject: [PATCH 01/10] chore: enable ruff PLC0415 and clear the import-outside-top-level backlog MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `extend-select = ["PLC0415"]` to `[tool.ruff.lint]` and resolves every resulting hit across src/, tests/, examples/, docker/, and band-bridge/ with one of three treatments: - Extras-gated: a local import for a module behind an optional pip extra not installed in every CI lane (adapters, `httpx` in opencode-only tests, etc.) gets `# noqa: PLC0415`. - Genuine violation: no real justification for locality — moved to the top-level import block (the large majority of fixes, concentrated in tests/). - Other legitimate reason, kept local with a documented `# noqa: PLC0415`: a verified real circular import (`band/agent.py`'s `PlatformSettings`/ `load_agent_config`, empirically proven by moving them and re-running `python -c "import band.agent"` — moving them reorders `band.agent`'s own `band.core.*` imports behind `band.config`, which re-enters `band.logging_config` mid-init), an always-loaded pytest plugin/conftest module where a top-level import would tax every test session regardless of whether the specific fixture is used (`tests/conftest.py`, `tests/markdown_docs/fixtures.py`, `tests/e2e/baseline/fixtures/platform.py`), or a test whose entire subject is the import statement itself (`test_readme_snippets.py`, `test_lazy_exports.py`, `test_band_import.py`). `uv run ruff check .` passes clean repo-wide, `uv run ruff format .` is a no-op, `uv run pyrefly check` reports 0 errors, and the full unit suite (5272 passed, 123 skipped) is green.

Reclassifies most remaining bucket-1 "extras-gated" sites: dev bundles every framework's third-party deps except crewai/parlant, so only those two, plus files ci.yml confirms run under crewai/parlant's isolated venvs, plus import-surface pin tests, plus files with no top-level SDK import already, keep a genuine deferral reason. Everything else was either 100% redundant (a local import shadowing a name already loaded at the file's own top level, ~110 sites across dozens of files) or had no real justification and moves to top-level. Adds a real one-line reason to every remaining noqa'd site that isn't already self-documented by a try/except guard. Caught and reverted one regression along the way: band/adapters/ langgraph.py's local imports look like the same "already loaded at top" redundancy, but tests patch band.integrations.langgraph.langchain_tools and langchain.agents.create_agent at their source module, which only works if the adapter looks them up at call time.

Also clarifies why test_crewai_flow_adapter.py's lazy-import test keeps its import local (it's the band.adapters lazy loader itself under test).

Hoisted both to real top-level imports. - band.integrations.a2a, .a2a.gateway, and .slack still eagerly import their adapter module from __init__.py, which is what made their converters' cycles genuinely real. Made all three lazy via the same lazy_exports helper band.adapters/band.converters already use (matching the pattern band.integrations.acp already proved out), then hoisted the now-safe converter imports. - src/band/adapters/langgraph.py kept three imports local not because of an optional extra, but because tests patched the original module (langchain.agents.create_agent, .langchain_tools.agent_tools_to_langchain) and a local import was the only way the patch took effect. Imported the modules themselves at top level and switched call sites to attribute access instead, so the existing mock.patch targets keep working with a real top-level import. - tests/skills/bughunting/test_runner.py deferred one toolkit import to "avoid pulling the e2e baseline toolkit into every skills-test collection", but two sibling submodules of the same toolkit were already imported unconditionally in the same file. - tests/framework_configs/adapters.py deferred CrewAIAdapter/ CrewAIFlowAdapter behind "isolates the crewai extra", but both classes import cleanly with crewai absent (verified against this repo's crewai-less dev venv) — same treatment ClaudeSDKAdapter already got in this file. - tests/runtime/test_human_tools.py imported ChatMessageRequest/ ParticipantRequest from band_rest directly instead of the band.client.rest re-export the same file already imports from. - examples/slack/01_basic_bot.py hoisted `import uvicorn` to module scope, but SLACK_TRANSPORT defaults to socket mode, which never touches uvicorn; moved back into the http-transport branch. Full unit suite (5272 passed), ruff, and pyrefly all clean.

Confirmed genuinely necessary and left alone: extras truly absent from a venv with a friendly ImportError, real circular imports, per-branch extra-selection in multi-framework example scripts, and tests whose literal subject is the import statement itself (~200 remaining instances). Hoisted the ones that weren't: - tests/framework_configs/{adapters,converters,output_adapters}.py: nearly the entire "isolates the X extra" registry pattern turned out to be unfounded. Every converter module (band.converters.*) only ever transforms dicts/dataclasses and has zero third-party imports at its own top level, so all 24 "isolates" deferrals in converters.py were pointless — hoisted the lot into one top-level block. In adapters.py, ParlantAdapter/GoogleADKAdapter both construct with their SDK absent (verified empirically for parlant, by source inspection for google_adk: every import is TYPE_CHECKING-only or method-local), and Codex/Opencode have no pip package at all (they shell out to a CLI) — hoisted all four. - src/band/integrations/codex/websocket_client.py: `websockets` is not actually optional — band-sdk's own hard dependency phoenix-channels-python-client requires it unconditionally, so every install has it. Hoisted, and switched to a module-level `import websockets.asyncio.client` with attribute-access calls (not `from ... import connect`) so the existing `monkeypatch.setattr("websockets.asyncio .client.connect", ...)` test patches keep working — bare `from X import Y` would have bound a stale local copy, same pitfall as the langgraph.py fix in the previous commit. - src/band/integrations/acp/cli.py: `from band import Agent` was grouped with three genuinely acp-extra-gated imports, but `band.Agent` doesn't need the acp extra — this file's own top-level `band.config.logs` import already runs all of band/__init__.py, which unconditionally binds Agent. - tests/e2e/baseline/toolkit/provisioning.py: `build_adapter`'s own module has no unconditional third-party imports either, and no cycle back to provisioning.py exists. - tests/adapters/test_crewai_flow_phase3.py: one test re-imported nest_asyncio locally with its own try/except+skip instead of using the module's existing `requires_nest_asyncio` marker and top-level `_HAS_NEST_ASYNCIO` guard, which every other nest_asyncio-dependent test in the file already does. Full unit suite (5272 passed), ruff, and pyrefly all clean.

Verified live: both modules import cleanly on main without the extras, and fail on this branch; restoring the TYPE_CHECKING + deferred-import pattern (now noqa'd with the real reason) fixes it on both.

Any pytest run that collects tests/framework_conformance/conftest.py under the dev-crewai or dev-parlant venvs (neither installs agno, gemini, langchain, pydantic_ai, or strands) now fails at import time instead of just skipping those configs.
