Solve the following python programming problem given the following code:
def Generate(self, filepath) : 
    curPath = self.GetProjectRoot (filepath) 
    stream = subprocess.Popen ((((('cd ' + curPath) + ' && ') + cli) + ' generate'), shell = True, stdout = subprocess.PIPE, stderr = subprocess.STDOUT) 
    def onGenerationEnd(retcode) : 
        if (retcode > 0) : 
            if (retcode == 127) : 
                editor.error (pathError) 
else : 
                editor.error ('Error occured, code: {0}'.format (str (retcode))) 
return 
server.restart () 
        editor.progress (100) 
        editor.notify ('Index generated') 
def ProcessGenerationPoll() : 
        retcode = stream.poll () 
        if (retcode is not None) : 
            onGenerationEnd (retcode) 
            return 
line = stream.stdout.readline () 
        errorMatch = re.search ('Error: (.*)', line) 
        if (errorMatch is not None) : 
            retcode = 1 
            editor.error ('{0}'.format (errorMatch.group (1).replace ("'", "''"))) 
            return 
match = re.search ('Progress: ([0-9]+)', line) 
        if (match is None) : 
            return True 
progress = int (match.group (1)) 
        editor.progress (progress) 
        return True 
editor.callAfter (0.0001, stream) 

    
    

    Fix the buggy line: editor.callAfter (0.0001, stream)
