Interactive Web-Based Debugging
When debug mode is enabled (set in the ini config), you’ll get interactive
web-based debugging when an exception occurs.
You can view the entire stack trace, with local variables and their
values, and even execute code in any context of the trace.
If you’re using the Paster server and you have if you have
installed, try calling
at some point in your code; it’ll act as a breakpoint and open up an IPython
shell with the local scope for you to play with.
