[jira] [Created] (THRIFT-4892) SASL data type exception for PLAIN

James E. King III created THRIFT-4892:
-----------------------------------------

             Summary: SASL data type exception for PLAIN
                 Key: THRIFT-4892
                 URL: https://issues.apache.org/jira/browse/THRIFT-4892
             Project: Thrift
          Issue Type: Bug
          Components: Python - Library
    Affects Versions: 0.12.0
            Reporter: James E. King III
            Assignee: James E. King III
             Fix For: 0.13.0


From: https://github.com/apache/thrift/pull/1804

A small data type mistake were observed during usage of SASL mechanism="PLAIN".
on 379-380 lines there're 2 calls of send_sasl_msg, where 1st uses sels.sasl.mechanism, which is of type str(), while 2nd uses self.sasl.process(), which generates bytes().

exception happens on line 402, where header generated on line 401 using pack() which returns type bytes() being concatenated with body provided to send_sasl_msg() func.
Since self.transport.write accepts bytes() only, it's better to use bytes everywhere...

on the line 420 we have similar error, where str().join() is being called, but both parameters passed to it are of type bytes(), which raises an exception.
