GitHub user mygityf opened a pull request:

    https://github.com/apache/thrift/pull/824

    To check element of self whether nil or not,avoid the value(false) of…

    … BOOL is lost.
    
    eg.
    Before:
      if self.argBool then
        oprot:writeFieldBegin('argBool', TType.BOOL, 13)
        oprot:writeBool(self.argBool)
        oprot:writeFieldEnd()
      end
    
    After:
      if self.argBool ~= nil then
        oprot:writeFieldBegin('argBool', TType.BOOL, 13)
        oprot:writeBool(self.argBool)
        oprot:writeFieldEnd()
      end
    
    Why:
      the value(false) for paramater self.argBool will be lost when condition 
is 'if self.argBool then' as before.
