Walkthrough

The changes introduce two new utility functions, sanitize_url and sanitize_intersphinx_mapping, within the documentation utilities module. These functions are used in the documentation configuration to ensure that all URLs and intersphinx mappings are validated and sanitized according to allowed schemes and domains. The sanitization process is applied to GitHub URLs, linkcode URL prefixes, and the intersphinx mapping dictionary, as well as to the output of the linkcode_resolve function. No changes are made to public API signatures; the modifications are limited to internal usage and configuration.

Changes

File(s) Change Summary
docs/utils.py Added sanitize_url and sanitize_intersphinx_mapping functions, plus constants for allowed URL schemes and domains.
docs/conf.py Integrated the sanitization utilities to process documentation URLs and intersphinx mappings.
tests/test_extra.py Added new test suite for sanitize_url covering URL encoding and validation scenarios.
tests/init.py Added optional import of test_extra tests for extended coverage and security tests.
tests/check_spelling Added new specific typo pair "belone:belong" for regression testing of spelling errors.

In the docs a rabbit hops,
Sanitizing URLs, it never stops!
Only trusted links may pass,
Through the filter, safe at last.
With every hop, the docs grow bright—
Secure and tidy, pure delight!

19-20: Appropriate imports for URL sanitization

The addition of imports from urllib.parse is appropriate for the new URL sanitization functionality. This choice follows the learning that Reactive-firewall prefers to reuse already loaded modules to keep memory overhead low.


240-270: Clean intersphinx mapping sanitization function

The sanitize_intersphinx_mapping function is concise, well-documented, and includes appropriate test cases. It effectively applies URL sanitization to each URL in the mapping while preserving the dictionary structure.

The implementation as a one-liner dictionary comprehension is elegant and follows Pythonic coding practices. It also preserves the extra values in the mapping, which is important for maintaining intersphinx functionality.

20-20: Appropriate import selection for URL handling

The urlparse, urlunparse, and quote functions from urllib.parse are perfect for URL manipulation and sanitization. Using standard library components rather than introducing external dependencies is a good practice, which aligns with your preference for keeping dependencies minimal.


30-39: Secure implementation with explicit domain allowlisting

Using frozenset for security-critical constants prevents accidental modification during runtime, which is a security best practice. The explicit domain allowlisting approach (rather than pattern matching) follows the "Avoid Hasty Abstraction" principle, providing precise control over which domains are permitted.


42-67: Well-defined URL length restriction with comprehensive tests

The 2048-character limit reflects common browser constraints, making this a practical choice. The embedded doctests provide complete validation of the constant's properties, ensuring the value remains within expected ranges.


70-131: Well-structured error message constants with integrated tests

Defining specific error messages as constants improves code maintainability and readability. Each constant has embedded unit tests verifying its existence and type, which is an excellent practice for ensuring constant integrity.


268-289: Robust URL validation and sanitization logic

The implementation follows security best practices by:

  1. Validating URL length before processing
  2. Checking both scheme and domain against allowlists
  3. Using safe parameter values in quote() to preserve URL structure while encoding potentially dangerous characters
  4. Properly reconstructing the URL with all components

The safe parameter usage (safe="/=" for paths and safe="&=" for queries) strikes an excellent balance between security and functionality.


292-322: Clean implementation of intersphinx mapping sanitization

The function elegantly applies URL sanitization to each URL in the mapping while preserving associated extra values. The dictionary comprehension is concise and readable, and the included doctests demonstrate both basic functionality and handling of special characters.
