As Get-ItemProperty output is different → parsing fails

• Number of lines
• Number of digits

Windows PowerShell 5.1

PowerShell 7

In addition the output is colored:

b'd----          29/12/2023  6:01 PM                \x1b[44;1mWindows\x1b[0m'

Describe the solution you'd like

facts/windows_files.py → class File(FactBase): → process method

• from

    def process(self, output):
        if len(output) < 7:
            return None
  
        # Note: The first 7 lines are header lines
        return parse_win_ls_output(output[7], self.type)

• to

    def process(self, output):
        if len(output) < 5:
            return None
  
        # Note: The first lines are header lines
        return parse_win_ls_output(output[-2], self.type)

facts/util/win_files.py → WIN_LS_REGEX definition, relax the filetype and mode pattern

• from

          # filetype and mode
          r"^([darhsl\-]{6})\s+"

• to

          # filetype and mode
          r"^([darhsl\-]{5,6})\s+"

facts/util/win_files.py → parse_win_ls_output function, remove ansi sequences

• from

    if output:
        matches = re.match(WIN_LS_REGEX, output)

• to

    if output:
  
        # Patch to remove ansi sequences from PowerShell 7
        # @see https://stackoverflow.com/questions/14693701/how-can-i-remove-the-ansi-escape-sequences-from-a-string-in-python
        ansi_escape = re.compile(r"(\x9B|\x1B\[)[0-?]*[ -/]*[@-~]", flags=re.IGNORECASE)
        output = ansi_escape.sub('', output)
  
        matches = re.match(WIN_LS_REGEX, output)

I think a much more future-proof, clean and safe (with respect to various kinds of injections when running commands on untrusted hosts) way is to use a proper serialization (JSON/XML) for transport. It is even much easier to handle the results on pyinfra's side while simply switching from Get-ItemProperty -Path C:\Windows to Get-ItemProperty -Path C:\Windows | ConvertTo-Json and possibly requesting only a subset of fields for efficiency.
