Re: [Discuss-gnuradio] catching unrecognized exception

[Nemanja Savic]

It's commented line inside the function called only once inside constructor, and never again :)

The '(65)' looks to be the line number where the error occured.  Notice that previously the line number was '(62)' which probably means that the error is coming from line 65 of one of the files you have been editing.

Hi again,

so, the exception appeared again. Just to remind:
thread[thread-per-block[0]: <gr_block db_logger2 (65)>]: caught unrecognized exception

I can't find what (65) means.

This time complete block of code was encapsulated by try and except but nothing was caught.

Here is my code:

    def handle_msg(self, msg):
        try:

            message = pmt.pmt_symbol_to_string(msg)
            msg_lines = message.split('\n')

            sensor_id = msg_lines[0]
            vendor = msg_lines[2]
            sensor_type = msg_lines[3]
            time = msg_lines[1]

            querry = "INSERT INTO `%s`.`%s` (`id` ,`sens_id` ,`vendor`, `sensor_type`, `det_id`) VALUES (NULL , '%s', '%s', '%s','%s');" % (self._db_name, self._det_table, sensor_id, vendor, sensor_type, self._id)

            cur = self._con.cursor()
            cur.execute(querry)
        except mdb.Error, e:
            print "Unexpected error while trying to insert into table"

            print 50*'-'

            print 50*'-'
            print "Error %d: %s" % (e.args[0],e.args[1])
            sys.exit(1)

        except:
            print 'msg handler exception'
            print 50*'-'
            print message

            print msg_lines
            print 50*'-'

Except this function there is also constructor and additional function for setting the database up (it is called only in constructor). There is no work function as this block nly receives messages and writes to database.

Is there any idea how can I catch this?

Thanx

Hi Nemanja,

your except syntax is wrong, most probably you wanted to use "except
ExceptionType as e" instead, refer to
http://docs.python.org/2/tutorial/errors.html

Anyway, have you tried surrounding all your handler code with a try
and catch not only the database related errors?

Greetings,
Marcus
