Direzione di ricerca

Read backend/secuscan/parser_sandbox.py to inspect _sanitize_stderr() and the existing tests in testing/backend/unit/test_parser_sandbox.py and testing/backend/unit/test_parser_sandbox_helpers.py. Add the requested cases in testing/backend/unit/test_parser_sandbox_stderr_sanitize.py and run that test file. Done means the tests cover path and line replacement, case handling, multiple matches, unchanged text, truncation, and replacement order; a linked pull request is already present.

Descrizione

Summary of What Needs to be Done:
Add unit tests for the _sanitize_stderr() helper function in backend/secuscan/parser_sandbox.py. This function strips absolute file paths and Python line-number references from stderr output before logging, to prevent leaking internal topology in diagnostic logs.

The existing test file testing/backend/unit/test_parser_sandbox.py covers 27 tests and testing/backend/unit/test_parser_sandbox_helpers.py covers the environment sanitization helpers, but _sanitize_stderr is not imported or tested in either file.

Changes that Need to be Made:
Create a new file testing/backend/unit/test_parser_sandbox_stderr_sanitize.py:

  • Import _sanitize_stderr from backend.secuscan.parser_sandbox
  • Test that absolute Unix paths (e.g. /home/user/project/file.py) are replaced with [PATH]
  • Test that Windows absolute paths (e.g. C:\Users\project\file.py) are replaced with [PATH]
  • Test that Python line number references (e.g. "line 42", "Line 1") are replaced with [LINE]
  • Test that the function is case-insensitive for line number matching
  • Test that multiple occurrences are all replaced
  • Test that text without paths or line numbers is returned unchanged
  • Test that the output is truncated to the max_chars default (500) for very long inputs
  • Test that max_chars parameter controls the truncation length
  • Test that the order of replacement is path first, then line numbers

Impact that it would Provide:

  • Prevents internal file paths and line numbers from leaking into operator-facing logs
  • Ensures the sanitizer handles edge cases (no paths, multiple paths, mixed content)
  • Validates the truncation behavior to prevent memory issues from huge stderr

Note: This task is being handled by tmdeveloper007 — please assign to that account when picking it up.
