Pdb, the Python debugger, has severe limitations (apart from some bugs). This extension tries to get rid of some of them.

Things done

  • setting breakpoints

Allow filename to specify a module as well.

Allow setting breakpoints from outside via do_break. This is useful for debug setups.

  • exception display

The current display of an exception is almost useless. In the Pdb code, exceptions are displayed at 4 places -- and each of them uses slightly different code (whow!).

We consolidate this into a single function _handle_exception and present the exception with traceback.format_exception_only. We also store the exception in the Pdb instance. A new command exception (abbreviated e) presents this stored exception value in a way similar to the where command.

  • where command improvements
  • each frame identifies its level (the top frame is at level 0,

System Message: WARNING/2 (<string>, line 33)

Bullet list ends without a blank line; unexpected unindent.

the one below it at level 1, etc...)

  • the current frame is marked as such
  • where gets optional arguments number and end

number controls how many frames are displayed (default: maxint), end at what level the display ends, negative numbers count from the bottom (default: -1, i.e. the bottom frame).

  • new command frame level (abbr: f)

switch to call frame at level

without argument, provide info about current frame

  • allow to customize the display of the where command

System Message: WARNING/2 (<string>, line 50)

Bullet list ends without a blank line; unexpected unindent.

and of tracebacks e.g. to display additional debugging information as provided by Zope (for example).

This can be done by customizing getAdditionalFrameInfo.

Things not yet done

  • Returning from debug occasionally returns to stop

System Message: WARNING/2 (<string>, line 60)

rather than where we entered the recursive debugger. This is often nasty (and should be fixed)
