Summary

Fixes unused variable warning in title sync tests for cleaner CI runs.

Changes

  • Fixed linting issue: changed result = to _ = in test_title_sync.py
  • Version bumped to 1.14.2
  • CHANGELOG.md updated

Files Modified

  • tests/unit/test_title_sync.py: Fixed unused variable warning
  • src/rxiv_maker/__version__.py: Bumped version to 1.14.2
  • CHANGELOG.md: Added v1.14.2 release notes

Release Notes

This is a patch release addressing test linting issues.

This commit addresses two issues:

1. Paragraph spacing: Increased \parskip from 0.5 to 0.75 baselineskip
   to provide better visual separation between paragraphs and sections
   when paragraph indentation is disabled. This prevents sections from
   appearing to run together in the PDF output.

2. Validate command hanging: Disabled DOI validation by default in the
   validate command to prevent indefinite hanging on network calls.
   The DOI validator uses ThreadPoolExecutor with network requests
   that can timeout or hang, causing the validate command to become
   unresponsive. The pdf command already disables DOI validation,
   and this change aligns the validate command with that behavior.

Files modified:
- src/tex/style/rxiv_maker_style.cls: Increase parskip to 0.75
- src/rxiv_maker/cli/framework/content_commands.py: Disable DOI validation
  and suppress bandit security warning with explanatory comment
…efinitely

- Add signal-based timeout wrapper in CitationValidator around DOI validation
- Reduce HTTP client timeouts from 10s to 5s and retries from 3 to 2
- Apply aggressive timeouts to all DOI API clients (CrossRef, DataCite, etc.)
- Reduce ThreadPoolExecutor timeout from 30s to 20s in DOI validator
- Add debug logging to track validation progress
- Fix bandit security warning (B110) with nosec comment

The timeout ensures that 'rxiv validate' completes within 30 seconds even
if DOI validation hangs on slow network calls, instead of hanging indefinitely.
If timeout occurs, validation continues with other checks and shows a clear
error message suggesting to use --no-doi flag.

This fixes the issue where 'rxiv validate' would hang forever on DOI
validation with slow or unresponsive network connections.
### Fixed
- Equation references now display as "Eq. 7" instead of just numbers
- PDF: Changed from \eqref to Eq.~\ref to avoid automatic parentheses
- DOCX: Now outputs "Eq. 7" instead of just "7"
- Prevents double parentheses in text like "(Eq. @eq:id)"
- Maintains consistency between PDF and DOCX outputs

### Changed
- src/rxiv_maker/converters/figure_processor.py: Updated convert_equation_references_to_latex()
- src/rxiv_maker/exporters/docx_exporter.py: Updated equation reference replacement
- src/rxiv_maker/__version__.py: Bumped to 1.14.1
- CHANGELOG.md: Added v1.14.1 release notes
Fix linting error: unused variable 'result' in test

Pull Request Review: v1.14.2 - Fix test linting

Thank you for this clean-up release! I've reviewed the changes across all modified files. Here's my feedback:


Positives

Code Quality

  • Test fix is correct: Changing result = to _ = properly addresses the unused variable warning (test_title_sync.py:469)
  • Consistent style: Follows Python conventions for explicitly ignoring return values
  • Good documentation: CHANGELOG.md is comprehensive and well-structured
  • Version bumping: Properly updated in __version__.py

Other Improvements Included

The PR includes several other quality improvements from v1.14.1:

  • Better equation reference formatting
  • Performance optimizations for DOI validation
  • Improved timeout handling

⚠️ Issues & Concerns

1. CRITICAL: Platform Compatibility Issue (citation_validator.py:153-154)

signal.signal(signal.SIGALRM, timeout_handler)
signal.alarm(30)  # 30-second timeout

Problem: signal.SIGALRM is Unix-only and will fail on Windows.

Impact: This breaks cross-platform compatibility, which contradicts the project's stated priority ("Platform Support: Cross-platform compatibility").

Recommendation: Use threading.Timer or concurrent.futures.TimeoutError instead:

import concurrent.futures

with concurrent.futures.ThreadPoolExecutor() as executor:
    future = executor.submit(doi_validator.validate)
    try:
        doi_result = future.result(timeout=30)
    except concurrent.futures.TimeoutError:
        logger.warning("DOI validation timed out...")

2. Security: Overly Broad Exception Handler (content_commands.py:370)

except Exception:  # nosec B110
    # Silently fall back to default if config is invalid or missing bibliography key
    pass

Problem: While # nosec B110 suppresses Bandit warnings, catching all exceptions masks real errors.

Recommendation: Be more specific:

except (yaml.YAMLError, KeyError, AttributeError, FileNotFoundError):
    # Silently fall back to default
    pass

3. Performance: Aggressive Timeout May Be Too Restrictive (doi_validator.py:114-115)

client_timeout = 5  # Reduced from default 10s
client_retries = 2  # Reduced from default 3

Concern: 5-second timeout might be too aggressive for:

  • Users on slower networks
  • Academic networks with proxies
  • DOI services under load

Impact: May cause false failures in legitimate use cases.

Recommendation: Consider making this configurable or use more conservative defaults (7-8s timeout).

4. Code Duplication: Timeout Logic Duplicated (doi_validator.py:376-422 & citation_validator.py:143-186)

Both files implement similar timeout/cancellation logic for futures. This should be refactored into a shared utility function.


🧪 Test Coverage Gaps

Missing Tests:

  1. Equation reference conversion (figure_processor.py:127-144)

    • No tests found for the new Eq.~\ref{eq:id} format
    • Should test: double parentheses prevention, non-breaking space handling
  2. DOI validation timeout behavior (citation_validator.py:143-186)

    • No tests for the new 30-second timeout logic
    • Should test: timeout triggering, signal cleanup, error message generation
  3. Platform-specific signal handling

    • Need tests to verify graceful degradation on Windows

Recommendation: Add unit tests for the equation reference changes and timeout behavior.


🔒 Security Assessment

Positive:

  • # nosec B110 comment shows awareness of security scanning
  • No injection vulnerabilities introduced

Concerns:


📝 Documentation

Good:

  • CHANGELOG is detailed and user-friendly
  • Inline comments explain rationale (e.g., timeout reasons)
  • Docstring updated for equation references

Suggestions:

  • Document the Windows incompatibility in CHANGELOG or code comments
  • Add migration note if users relied on old \eqref behavior

🎯 Recommendations Summary

Must Fix (Blocking):

  1. Replace signal.SIGALRM with cross-platform alternative - This breaks Windows support

Should Fix (High Priority):

  1. ⚠️ Narrow exception handling in content_commands.py
  2. ⚠️ Add tests for equation reference conversion
  3. ⚠️ Add tests for timeout behavior

Nice to Have:

  1. 💡 Consider making timeout configurable
  2. 💡 Refactor duplicated timeout logic into shared utility
  3. 💡 Document platform compatibility considerations

🏁 Overall Assessment

The test linting fix itself is perfect - exactly the right approach for unused variables. However, the PR includes significant changes from v1.14.1 that introduce a critical cross-platform compatibility issue with Unix-only signal handling.

Verdict: ⚠️ Needs revision before merge due to Windows incompatibility.

The equation reference improvements and performance optimizations are welcome, but they need:

  • Cross-platform timeout implementation
  • Better exception handling
  • Additional test coverage

Please let me know if you'd like help implementing any of these fixes!

The exception handler catches all exceptions with a bare Exception and only logs a warning, which could hide critical errors. Consider being more specific about which exceptions are expected (e.g., TimeoutError, concurrent.futures.CancelledError) and re-raising unexpected exceptions after logging.

The # nosec B110 comment is added but the accompanying comment "Silently fall back to default if config is invalid or missing bibliography key" doesn't explain why this is safe from a security perspective. The nosec annotation should include a security-focused justification, not just a functional explanation. For example: "# nosec B110 - try/except/pass is safe here as it only handles config parsing errors with no security implications"

Suggested change
except Exception: # nosec B110

Hard-coded magic numbers for timeout (5 seconds) and retries (2) reduce configurability. These values are used throughout the initialization but aren't configurable by users or tests. Consider making these configurable parameters or class constants with clear documentation about why these specific values were chosen.

Hard-coded 20-second timeout is another magic number. The comment explains "With 5s timeout and 2 retries per DOI, 20s should be sufficient" but this calculation doesn't account for thread pool overhead, multiple DOIs, or network latency. Consider making this timeout configurable or computing it based on the number of DOIs and per-request timeout.

Hard-coded 30-second timeout is yet another magic number. This should be a configurable constant or parameter. Additionally, the relationship between this timeout (30s) and the DOI validation timeout (20s) is unclear and not documented.

Using ErrorCode.DOI_NOT_RESOLVABLE for a timeout error is misleading. A timeout is different from a DOI that cannot be resolved - it might be resolvable but the network was slow or unavailable. Consider using a more appropriate error code or creating a new one like DOI_VALIDATION_TIMEOUT.

The changelog describes v1.14.2 as only fixing test linting, but the PR includes substantial changes to DOI validation (timeouts, logging), equation references, style formatting, and security annotations. These changes are not documented in v1.14.2's entry. Either the version number is incorrect (these might be v1.14.1 changes), or the changelog is incomplete. This creates confusion about what's actually in this release.

Suggested change
- **DOI validation improvements**: Enhanced DOI validation logic with timeouts and logging
- Added timeout handling to prevent hanging on slow DOI lookups
- Improved logging for DOI validation failures and successes
- Modified `validate_doi()` in `src/rxiv_maker/utils/doi_validator.py`
- **Equation reference formatting**: Improved equation references for consistency and clarity
- PDF output now uses `Eq.~\ref{eq:id}` instead of `\eqref{eq:id}` to avoid automatic parentheses
- DOCX output now shows "Eq. 7" instead of just "7"
- Prevents double parentheses when users write text like "(Eq. @eq:id)"
- Maintains consistency between PDF and DOCX outputs
- Non-breaking space (~) ensures "Eq." and number stay together in PDF
- Modified `convert_equation_references_to_latex()` in `src/rxiv_maker/converters/figure_processor.py`
- Modified equation reference replacement in `src/rxiv_maker/exporters/docx_exporter.py`
- **Style formatting**: Updated style formatting for improved readability and consistency

The use of signal.SIGALRM and signal.alarm() is Unix-specific and will fail on Windows systems. This breaks cross-platform compatibility. Consider using threading.Timer or concurrent.futures.TimeoutError with the executor's timeout parameter instead, which work across all platforms.

The comment states "Use the same aggressive timeout and retry settings for fallback APIs" but the code ignores the self.fallback_timeout attribute that was previously used. This creates inconsistency where the fallback_timeout parameter passed to the constructor is now unused, which could confuse users who set this parameter expecting it to work.
