This PR enables the D flag for Ruff checks, and fixes all associated errors

rwkeane and others added 3 commits June 21, 2025 18:05
This commit includes fixes for a subset of pydocstyle `D` rule
violations, primarily focusing on:
- D401: Ensuring the first line of docstrings is in the imperative mood.
- D100/D102/D104/D107: Adding missing docstrings for modules, methods,
packages, and __init__ methods.
- D205: Ensuring one blank line between summary and description.
- D301: Using raw string literals for docstrings with backslashes.
- D417: Adding missing argument descriptions.
- D418: Addressed by ensuring overloads have docstrings as per specific
prompt instructions.

Files addressed so far include:
- docs/conf.py
- tsercom/__init__.py
- Various files under tsercom/api/
- Various files under tsercom/caller_id/
- Various files under tsercom/data/

Further work is pending to address all remaining `D` rule violations
across the codebase.

Static analysis:
- `black .` passes.
- `mypy tsercom/` has pre-existing errors; no new errors were introduced
by these changes. Unused `type: ignore` comments were removed.
- `ruff check . --select D` will be fully addressed in subsequent
commits.

Testing:
- `pytest --timeout=120` (run via `PYTEST_TIMEOUT=120 python -m pytest`)
passed twice with 970 tests passing, 11 skipped, and 13 warnings. No new
test failures were introduced.

This commit addresses multiple aspects of codebase health:

1.  **Test Failures:**
* Resolved 3 failing tests in `tsercom/runtime_e2etest.py` related to
out-of-process error propagation and handling. The fixes involved
improving synchronization using `multiprocessing.Event` to ensure child
process errors are reliably detected by the parent `RuntimeManager`.
Affected tests:
        *   `test_out_of_process_error_check_for_exception`
        *   `test_out_of_process_error_run_until_exception`
        *   `test_out_of_process_initializer_create_error`

2.  **Overload Docstrings:**
* Ensured all functions using `@typing.overload` (aliased as
`@overload`) have complete Google-style docstrings for each individual
overload signature and for the main implementation. This involved adding
or verifying docstrings in files such as:
        *   `tsercom/api/runtime_handle.py`
        *   `tsercom/runtime/runtime_data_handler.py`
        *   `tsercom/runtime/runtime_data_handler_base.py`
        *   `tsercom/tensor/demuxer/stream_receiver.py`
        *   `tsercom/tensor/muxer/aggregate_tensor_multiplexer.py`
* Files like `tsercom/data/remote_data_aggregator.py`,
`tsercom/data/remote_data_aggregator_impl.py`,
`tsercom/discovery/discovery_host.py`,
`tsercom/runtime/endpoint_data_processor.py`, and
`tsercom/runtime/id_tracker.py`, `tsercom/runtime/runtime_config.py`
were reviewed and found to already have compliant overload
documentation.

3.  **Ruff Issues:**
* Added `D418` (Function decorated with @overload is missing a
docstring) to the ignore list in `pyproject.toml` as the main
implementation docstrings are intentionally brief when overloads are
fully documented.
* Ran `ruff check . --fix` to automatically correct applicable issues.
    *   Manually addressed remaining Ruff violations, including:
* `E501` (Line too long) by shortening docstrings, comments, and code
lines.
* `D401` (First line of docstring should be in imperative mood).
* Other `D` series docstring convention errors (D100, D101, D102, D103,
D105, D107, D203, D205, D210, D211, D212, D213, D404, D413, D417).
        *   `W293` (Blank line contains whitespace).
* Corrected syntax errors that were inadvertently introduced during
manual E501 fixes by ensuring docstrings were properly formatted.
    *   The codebase now passes `ruff check .` cleanly.

4.  **Static Analysis and Verification:**
    *   Ran `black .` to format the code.
* `mypy tsercom/` was run; identified errors were pre-existing and not
introduced by these changes.
* The full test suite (`pytest --timeout=120`) was run twice
successfully after all changes to ensure no regressions.

This work improves test reliability, documentation quality, and code
style adherence across the `tsercom/` codebase.
