Bug 221855 – _W3CTestConverter tests don't run on Windows

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Don Olmstead]

When running Tools/Scripts/test-webkitpy on Windows saw the following when running the webkitpy.w3c.test_converter_unittest.W3CTestConverterTest test suite.

  Traceback (most recent call last):
    File "C:\tools\python3\lib\sre_parse.py", line 1039, in parse_template
      this = chr(ESCAPES[this][1])
  KeyError: '\\L'
  
  During handling of the above exception, another exception occurred:
  
  Traceback (most recent call last):
    File "C:\webkit\Tools\Scripts\webkitpy\w3c\test_converter_unittest.py", line 89, in

    File "C:\tools\python3\lib\re.py", line 210, in sub
      return _compile(pattern, flags).sub(repl, string, count)

    File "C:\tools\python3\lib\re.py", line 327, in _subx
      template = _compile_repl(template, pattern)
    File "C:\tools\python3\lib\re.py", line 318, in _compile_repl
      return sre_parse.parse_template(repl, pattern)
    File "C:\tools\python3\lib\sre_parse.py", line 1042, in parse_template

      raise s.error('bad escape %s' % this, len(this))
  re.error: bad escape \L at position 8

The issue stems from Window's path separator being '\' which gets used when creating a regex.

WIP Patch

This fixes the issue on Windows.

I'm not entirely sure the workflow so I'd like to run the whole thing through Windows to make sure this actually works works.

LGTM, not sure why webkitpy is unhappy though.
Let's try rerunning it.
