Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Ilya Sandler (isandler) Assigned to: Nobody/Anonymous (nobody) Summary: pdb sometimes sets breakpoints in the wrong location

Initial Comment:

If one attempts to set a breakpoint in one line function: e.g for this code:

def f(x): return x*x

z=23

pdb silently sets a breakpoint on the line right after the function definition (i.e. outside the function body!):

../python pdb.py.v1.66 pdb_one_line_func

(Pdb) b f Breakpoint 1 /src/Lib/pdb_one_line_func:3 (Pdb) c

-> z=23

It's probably acceptable to limit pdb breakpoints to multiline functions, but i don't think, it's acceptable to create wrong breakpoints.

Note: that anyone attempting to fix this should also take a look at bug 875404 (global statment causes breakpoints..), as both bugs are caused by pdb.checkline() logic
