Re: [Discuss-gnuradio] catching unrecognized exception
Hello again,
Marcus, you are right, my syntax is not any more correct but there is
backwards compatibility. I initiated error on my own and everything works
fine, so I would say there should be rather something more serious.

Hi Nemanja,
Simple explanation:
You haven't fixed your syntax for the first except clause.
Going back to my other post, it should read
except mdb.Error as e:, not except mdb.Error, e.
Because you didn't do that, e is undefined in your except clause.
This raises a NameError in your except clause, which doesn't get
handled. Fix the except syntax.
Also, don't do system.exit() in a multithreaded application, unless
you really know what you're doing. You'll end up with unfinished data,
broken database commits and so on.
Greetings,
Marcus

Except this function there is also constructor and additional

Re: [Discuss-gnuradio] catching unrecognized exception
the last message was not clear.
So, I made sql syntax error and run the program, with my old syntax, and
exception was caught, so the error should be somewhere else.

Hi Nemanja,
ah that's interesting, I've tried and for me, it fails. Strange. I'm
going to investigate that.
However, if that syntax is ok, then I'm out of ideas. You're not
giving out all too much details, though. When excatly does this
exception occur? Does your block work at all? Does it work when
commenting out functionality? How about print done this and that
debugging? Do your two blocks share the same database connection (if
that's the case, are you doing multithreading correctly?)?
My only guess would still be that one of your except clauses throws an
Exception. Maybe print message, if message = pmt.symbol_to_string()
failed?
By the way, caught unrecognized exception comes from the C++ domain,
it happens when there is an uncaught C++ exception, which might have
nothing to do with your executed python.
What you can do is run your program in a debugger, i.e.
$ gdb --args python your_python_flowgraph.py
...
(gdb)run
...
interrupt (ctrl-z), try to set a breakpoint at
gnuradio-runtime/include/gnuradio/thread/thread_body_wrapper.h:61 ,
then continue running your program
(gdb)cont
...
and see what happened prior to that call:
(gdb)bt

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,

thread[thread-per-block[0]: gr_block db_logger2 (65)]: caught

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]

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

Re: [Discuss-gnuradio] catching unrecognized exception
-BEGIN PGP SIGNED MESSAGE-

Hi Nemanja,
Simple explanation:
You haven't fixed your syntax for the first except clause.
Going back to my other post, it should read
except mdb.Error as e:, not except mdb.Error, e.
Because you didn't do that, e is undefined in your except clause.
This raises a NameError in your except clause, which doesn't get
handled. Fix the except syntax.
Also, don't do system.exit() in a multithreaded application, unless
you really know what you're doing. You'll end up with unfinished data,
broken database commits and so on.
Greetings,
Marcus
