📝 Walkthrough
WalkthroughUpdates minimum Python requirement to 3.9, modernizes type hints to built-in generics, and adds a type-definition plugin with an entry point and corresponding hook. Adds signature-formatting plumbing and Formatter implementations (Black/Ruff) used by hover/completion formatting. Reworks WebSocket outbound dispatch to use an asyncio.Queue and loop.call_soon_threadsafe. Miscellaneous: logger/help string tweaks, f-string conversions, IOError→OSError changes, CI Python-matrix updates, new tests and some skips, schema/config/README/SECURITY/CHANGELOG/docs updates, funding manifest entry, and pyproject metadata/dependency adjustments.

Sorry, something went wrong.
This comment was marked as off-topic.
Update test assertions to match the new hover and signature response formats introduced in commit cc0efee. The fork now returns structured list format for hover (signature + docstring) instead of markdown dict, and plain string documentation for signatures. Changes: - Update hover tests to expect list format with separate signature code block and docstring items - Update signature tests to expect string documentation instead of dict with "value" key - Skip 5 jedi tests incompatible with Interpreter mode (extra_paths, document_path completions/definitions, file completions, references) - Add helper function for extracting hover text from list format All modified tests now pass with the custom fork modifications.

test/plugins/test_signature.py (2)8-8: LGTM: Type hint modernization to PEP 585.
Built-in dict replaces typing.Dict, consistent with Python 3.9+ migration.
Also applies to: 69-69
285-286: Remove verification request—test doesn't require PyQt6 installation.
The test uses a string containing PyQt6 code to test Jedi's completion capability, not actual PyQt6 functionality. Like the adjacent test_numpy_completions test, it passes code strings to pylsp_jedi_completions without requiring the package itself. No dependency verification needed.
Likely an incorrect or invalid review comment.
test/plugins/test_hover.py (6)65-66: LGTM.
Test expectations correctly updated to match the new string-based parameter documentation format.
85-85: LGTM.
Consistent update for multi-line signature test.
test/plugins/test_definitions.py (2)13-13: LGTM.
Updated function signature provides better test coverage with typed parameters.
43-49: LGTM.
Clean helper to extract docstrings from list-based hover results.
52-65: LGTM.
Consistent use of get_hover_text helper for module hovers.
76-84: LGTM.
Test correctly validates the new two-item hover format with signature and docstring.
88-122: Tests document that signature formatting is not applied in hover.
Both tests assert identical output despite different signature config values, confirming hover returns raw Jedi signatures. This aligns with the unused signature_config in pylsp/plugins/hover.py.
If signature formatting should be applied in hover, the implementation needs completion. Otherwise, consider removing these config-related tests or clarifying their purpose.
144-156: LGTM.
Properly handles both list-based hover contents and empty results with clear fallback logic.
6-7: LGTM: Import necessary for skip decorator.
145-145: No action needed—skip is intentional and documented.
This skip is the intended fix for a known jedi.Interpreter mode limitation in the cc0efee custom fork changes. Commit 938aeb3 explicitly documents this: "Skip 5 jedi tests incompatible with Interpreter mode" with all tests now passing. The limitation is tracked by commit reference and accepted as part of the fork. There's no pending fix to track.

♻️ Duplicate comments (4)test/plugins/test_jedi_rename.py (1)📜 Review detailspylsp/plugins/jedi_completion.py (2)36-36: Use @pytest.mark.xfail with a tracking issue reference, not skip.
The prior review recommended using @pytest.mark.xfail with a tracking issue reference to preserve test visibility and coverage. skip hides the test from collection entirely, whereas xfail documents an expected failure while keeping the test in the suite. Also, replace the commit hash with a tracking issue number for clarity.
Consider updating to:
-@pytest.mark.skip(reason="Does not work with jedi.Interpreter mode (commit cc0efee)") +@pytest.mark.xfail(reason="Does not work with jedi.Interpreter mode; see issue #XXXX")(Replace #XXXX with the actual tracking issue number.)
pylsp/python_lsp.py (1)45-45: Use document-scoped settings for signature_config.
Should be config.settings(document_path=document.path).get("signature", {}) to respect per-workspace/project settings.

Should be config.settings(document_path=document.path).get("signature", {}).
449-451: Flatten typeDefinition results like definitions.
Hook returns list of results; without flatten you'll return nested list [[...], [...]] which breaks LSP clients. Line 447 shows the correct pattern for definitions.

pylsp/plugins/preload_imports.py (1)pylsp/workspace.py (8)10-50: Formatting change improves maintainability.
One module per line makes diffs cleaner when modules are added or removed.
pylsp/python_lsp.py (9)5-5: Import modernization aligns with Python 3.9+ minimum.
importlib.metadata and collections.abc.Generator are appropriate for the updated baseline.

One-per-line style improves diff clarity.
486-486: Quote style change only.
No functional impact.
491-499: Reformatted for readability.
Logic unchanged; uses modern importlib.metadata API.
520-520: Built-in open is correct for Python 3.
No need for io.open when targeting Python 3.9+.
544-554: Good optimization: cache self.lines locally.
Reduces lock contention and avoids repeated splitlines() calls.
578-582: Consistent optimization pattern.
Caching self.lines locally reduces property overhead.
645-645: Formatting change only.
pylsp/plugins/hover.py (1)11-11: LGTM!
Import needed for type annotation on line 511.
140-184: Verify initialization ordering to prevent race condition.
send_message (line 167) can be called via response_handler (line 147) before run_server (line 175) initializes loop and send_queue. If pylsp_handler.consume (line 163) triggers a response during the gap, line 171 will raise AttributeError: 'NoneType' object has no attribute 'call_soon_threadsafe'.
Verify that pylsp_ws (line 143) is only invoked after run_server initializes the queue and loop, or add a guard:
def send_message(message, websocket): """Handler to send responses of processed requests to respective web socket clients""" try: + if loop is None or send_queue is None: + log.warning("send_message called before initialization") + return payload = json.dumps(message, ensure_ascii=False) loop.call_soon_threadsafe(send_queue.put_nowait, (payload, websocket)) except Exception as e: log.exception("Failed to write message %s, %s", message, str(e))
260-260: LGTM!
Shutdown hook call follows established pattern.
308-308: LGTM!
Adds type definition provider capability.
415-415: LGTM!
Type hints improve clarity; built-in generics align with Python 3.9+.
436-438: LGTM!
Hook call pattern is consistent with other methods.
511-511: LGTM!
Type hint uses modern built-in generics (Python 3.9+).
750-754: LGTM!
Copying completion state to cell document enables proper completionItem/resolve for notebooks.
808-811: LGTM conditionally.
Method correctly delegates to type_definition (line 450). Ensure line 450 is fixed to flatten results.
59-59: Return shape consistency.
You currently return either a list or an empty string. Consider returning MarkupContent (dict) when contentFormat=plaintext (as above) and list only for markdown to avoid mixed semantics across clients.

test/test_notebook_document.py (1)test/plugins/test_completion.py (2)492-492: Skipped tests defer coverage without a clear fix timeline.
The skip decorator references commit cc0efee, which is a documented architectural change. While this explains why the tests break, it doesn't provide a path to re-enable them. Multiple tests across the codebase share this same skip reason, creating a pattern of deferred fixes. Consider:
- Adding a tracked issue or ticket to re-enable these tests post-cc0efee stabilization
- Documenting the specific jedi.Interpreter incompatibilities for future resolution
- Reviewing whether adapting the tests (as done elsewhere in the codebase) is feasible
8-8: LGTM! Clean migration to built-in generics.
The removal of Dict from typing imports and the update to use dict[str, TypeCase] correctly aligns with Python 3.9+ built-in generic support.
Also applies to: 69-69
285-286: PyQt6 is already present in test dependencies.
The pyproject.toml file includes PyQt6 in the test optional dependencies section. The code changes are properly supported.
Sorry, something went wrong.
Fix release workflow to properly resolve version from git tags instead
of defaulting to 0.0.0. The issue occurred because actions/checkout@v4
requires explicit tag fetching, unlike the older v2 used in upstream.
Changes:
- Add ref: ${{ github.ref }} to checkout the exact release tag
- Add fetch-tags: true to explicitly fetch all tags for setuptools_scm
This ensures setuptools_scm can properly determine the version from
git tags (e.g., v1.12.2.4-beta3 → 1.12.2.4b3) instead of falling back
to version 0.0.0.
Related: Previous releases incorrectly published as version 0.0.0

"mutli" should be "multi".
120-140: Identical assertions to formatting test.
Opt-out test expects same output as test_hover_signature_formatting, confirming that formatting may not be applied in the previous test.
43-50: Helper doesn't handle MarkupContent as previously suggested.
The past review recommended extracting "value" from MarkupContent dicts and from dict items within lists. Current code returns raw dicts.
Apply the previously suggested fix:
def get_hover_text(result): contents = result["contents"] + if isinstance(contents, dict) and "value" in contents: # MarkupContent + return contents["value"] if isinstance(contents, list) and len(contents) > 0: - # Return the last item which is the docstring - return contents[-1] + last = contents[-1] + return last.get("value") if isinstance(last, dict) else last return contentsBased on learnings
