http://www.zope.org/Members/rossp/PDBDebugMode PDBDebugMode - PDB post-mortem debugging on exceptions when debug-mode=on If a relevant error log object is found, exceptions included in the error log's ignored exception types will be ignored and the debugger won't be invoked. It also enables the import of the pdb module in unprotected code. On encountering an error, the port-mortem debugger is invoked with the error's traceback. Once in the debugger you can examine objects, variables, etc. at all levels of the call stack. This is, of course, extremely useful for debugging. Since it only does anything if the instance is running with debug-mode=on, I find this product useful not only for debugging on my development instances, but also for doing quick emergency debugging on a live production site. IOW, if the problem is only reproducable on the production site but not on my development instance, I'll restart the production instance in debug-mode with pdb in emacs, reproduce the error, inspect the call stack.
