I'm pretty new to Python, but I am really enjoying it as an alternative
to Perl and PHP.
When I run the debugger [import pdb; pdb.set_trace()] and then do next
and step, and evaluate variables, etc, when I hit 'c' for continue, we
go to the end, just fine.
As soon as I set a breakpoint down the line, [bline number] the
behavior of 'c' changes. Instead of continuing until the breakpoint, or
until the end, if the breakpoint is hidden by a conditional, the
debugger starts to treat 'c' as a step (or a next, I'm not sure which.)
This behavior is repeatable and consistent.
I see this in python 2.6.4 on Ubuntu 9.10 and also in 2.5.2 on Ubuntu
8.04 (Hardy), both using the installed packages.
I must be missing something. Assistance will be welcome.
I can't reproduce this. Please post a small script and debugger session
transcript that illustrate the problem clearly.
Maybe, on the way, you'll discover something you'd been missing. Maybe someone
here will be able to help you then (maybe someone is now, but not me...).
Maybe it's a bug (which it would be, if it behaves as you describe, but as I
said, it appears to work for me).
Here is my debugger session as requested. Note that I set a breakpoint
at line 7, but c still stops at lines 4, 5 and 6. I hope somebody can
explain this.
