[Bashdb-devel] Debugging inside a long or complicated program or speeding up debugging

[R. B. <ro...@pa...>]

In working with a debugger for python, I noticed a nice feature which
just had a chance to code up and try out in the bash debugger.

Rather than start a script inside the debugger, the python debugger
allows one to load the debugger at any place in the script and then
issue a call to enter give control to the debugger. 

Here's an example script 

  # Lots of stuff here. ...
  x=2
  source /usr/local/share/bashdb/bashdb-trace # or whereever
  _Dbg_set_trace
  y=3

You will be stopped before y=3 in the debugger. This mechanism allows
one to run lots of complex code which might otherwise get messed up by
the debugger. Another use might be in a large script where running the
debugger every step (e.g. configure) is just too slow.

At present I can't commit any of this code as sourceforge CVS is down
and has been so for two days. (Ironically, this is right when
sourceforge send out its monthly status report which was bragging
about how great they've been working hard on improving things
including reliablity.)
