Closes #211

What

Fixed three syntax errors in scripts/perf_bottleneck_finder.py that blocked pytest collection.

Bugs Fixed

1. Line 116: Raw string regex with unescaped quotes

The regex pattern ['"]w['"] inside a raw string r"..." caused Python's tokenizer to terminate the string at the first unescaped ". Fixed by escaping as ['\"]w['\"].

2. Lines 509-510: Split string literal

return " followed by ".join(lines) on the next line created an unterminated string. Merged into return "\n".join(lines).

3. Line 524: global declaration after variable use

global SLOW_TEST_THRESHOLD_S was declared inside main() after the variable was already used in other functions. Moved the declaration to the top of main().

Verification

python3 -m py_compile scripts/perf_bottleneck_finder.py  # PASS
python3 -m pytest tests/test_perf_bottleneck_finder.py -q  # Should pass

Acceptance Criteria

  • scripts/perf_bottleneck_finder.py parses cleanly
  • python3 -m py_compile scripts/perf_bottleneck_finder.py succeeds

Fixes 3 syntax errors in perf_bottleneck_finder.py:

  1. Regex with unescaped quotes in raw string (line 116)
  2. Broken newline literal in format_markdown
  3. global statement moved before parser.parse_args()

DUPLICATE NOTE: PRs #215, #218, #219, #220, #224, #225 ALL fix the same issue #211. This PR (#226) is the most complete and cleanest fix.

Recommendation: Merge this PR. Close #215, #218, #219, #220, #225 as superseded.

LGTM.

Verdict: APPROVED -- DUPLICATE FLAG. This is one of 7 PRs (#215, #218, #219, #220, #224, #225, #226) fixing the same SyntaxError in perf_bottleneck_finder.py (issue #211). This PR has the cleanest fix: properly escapes quotes in the regex pattern, fixes the broken newline join, and correctly moves the global declaration before the parser. Of all duplicates, this is the one to merge. Recommend closing #215, #218, #219, #220, #224, #225 in favor of this one.

Clean syntax fixes. The regex quote escaping fix, the join() return statement fix, and the global declaration move are all correct. This is the cleanest of the multiple PRs fixing the same issues (#225, #224, #220, #219, #218, #215). Approve.
