Summary: pdb 'run' crashes when the it's first argument is non-string
Initial Comment:
Pdb 'run/runeval' commands fails to check the type of
given argument.When argument to 'run/runeval' is
non-string the functions crashes with further
impilications on (correctly)invoking this functions:
Python 2.5a1 (trunk:45527, Apr 18 2006, 11:12:31)
>>> def x(): pass
>>> import pdb
>>> pdb.run(x())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/jkk/python/python-svn/Lib/pdb.py", line
1113, in run
Pdb().run(statement, globals, locals)
File "/home/jkk/python/python-svn/Lib/bdb.py", line
363, in run
cmd = cmd+'\n'
TypeError: unsupported operand type(s) for +:
'NoneType' and 'str'
>>> pdb.run('x()')
> /home/jkk/python/python-svn/Lib/pdb.py(1113)run()
-> Pdb().run(statement, globals, locals)
(Pdb)
# CTRL-D pressed
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/jkk/python/python-svn/Lib/pdb.py", line
1113, in run
Pdb().run(statement, globals, locals)
File "/home/jkk/python/python-svn/Lib/pdb.py", line
1113, in run
Pdb().run(statement, globals, locals)
File "/home/jkk/python/python-svn/Lib/bdb.py", line
48, in trace_dispatch
return self.dispatch_line(frame)
File "/home/jkk/python/python-svn/Lib/bdb.py", line
67, in dispatch_line
if self.quitting: raise BdbQuit
bdb.BdbQuit
The solution is to simply ensure that the first
argument passed to the 'run/runeval' functions is string.

I would not classify your example as a crash. You passed a
wrong value (None in your case) into pdb.run() and got back
a TypeError...Isn't it an expected response?
E.g if you do: >>>max(13)
You'll also get: "TypeError"
Am I missing something? Could you clarify?
