Wrong conf file encoding on windows

[zszia]

The app writes the conf files on windows with UTF-8-BOM Encoding. This leads to errors in the parse method in the conf_files_splunk_client.py

Possible solution would be to detect the encoding before parsing the files:

    # from requests.utils (guess_json_utf(data))
    def detect_encoding(self, path):
        _null = "\x00".encode("ascii")  # encoding to ASCII for Python 3
        _null2 = _null * 2
        _null3 = _null * 3
        with open(path, "rb") as fp:
            data = fp.readline()
        sample = data[:4]
        if sample in (codecs.BOM_UTF32_LE, codecs.BOM_UTF32_BE):
            return "utf-32"  # BOM included
        if sample[:3] == codecs.BOM_UTF8:
            return "utf-8-sig"  # BOM included, MS style (discouraged)
        if sample[:2] in (codecs.BOM_UTF16_LE, codecs.BOM_UTF16_BE):
            return "utf-16"  # BOM included
        nullcount = sample.count(_null)
        if nullcount == 0:
            return "utf-8"
        if nullcount == 2:
            if sample[::2] == _null2:  # 1st and 3rd are null
                return "utf-16-be"
            if sample[1::2] == _null2:  # 2nd and 4th are null
                return "utf-16-le"
            # Did not detect 2 valid UTF-16 ascii-range characters
        if nullcount == 3:
            if sample[:3] == _null3:
                return "utf-32-be"
            if sample[1:] == _null3:
                return "utf-32-le"
            # Did not detect a valid UTF-32 ascii-range character
        return "utf-8"

    def parse(self, path):
        if os.path.exists(path):
            parser = ConfigParser(
                delimiters=("="),
                strict=False,
                default_section="__default__",
            )
            encoding = self.detect_encoding(path)
            with open(path, "r", encoding=encoding) as fp:
                content = fp.read()

            content = content.replace("\\\n", "")
            parser.read_string(content)
            return parser
        else:
            return None
