LogParser - drain parser is old version

[Xtremely-Doped-Punk]

this is the latest drain parser source code: https://github.com/logpai/logparser/blob/master/logparser/Drain/Drain.py and there seems to a problem with the get_parameter_list() in line 339, which was given as 'template_regex = re.sub(r' +', r'\s+', template_regex)' which is been causes the result's parameters to be empty list, also the original source code is not yet committed with the correct sequence code, this should do it. ''' def get_parameter_list(self, row): template_regex = re.sub(r"<.{1,5}>", "<>", row["EventTemplate"]) if "<>" not in template_regex: return [] template_regex = re.sub(r'([^A-Za-z0-9])', r'\\1', template_regex) template_regex = re.sub(r'\ +', r'\s+', template_regex) # changed template_regex = "^" + template_regex.replace("\<*>", "(.*?)") + "$" parameter_list = re.findall(template_regex, row["Content"]) parameter_list = parameter_list[0] if parameter_list else () parameter_list = list(parameter_list) if isinstance(parameter_list, tuple) else [parameter_list] return parameter_list '''
