Hi,
I have a two fold question:
-how to attach the debugger to running multi threaded program
-the objective is to find an infinite loop in one of threads which
makes the whole thingy going craze (100%CPU)
The program itself is not easy, in fact quite hude and sometimes it
takes hours to get to that infloop state.
Any insight?

On linux:
% python
>>import os os.getpid()
54321
Now, in another shell,
% gdb
(gdb) attach 54321
If you want debugging symbols, recompile python with -g.

Thx for the reply. But I wish to debug the python program, not python
interpreter itself.

I haven't used this, but it looks like it's worth a try: http://hapdebugger.sourceforge.net/
You may try winpdb.
I find it to be a comfortable debugger that also can attach to running
programs. (You need to add a line in your code where the program should
stop and wait for the debugger to attach.)
I am satisfied with it, but I did not debug a multi theaded app.
However, it can handle threads. I'd be glad to later hear whether it
did what you need, or not: http://www.digitalpeers.com/pythondebugger/threads.htm

Okay, a bit of an exaggeration.
Recently, I've been using Python more seriously, and in using the
debugger I think one of the first things I noticed was that there is
no "restart" ("R" in perldb) or "run" (gdb) command.
I was pleasantly pleased discover how easy though it was patch pdb.py
and pdb.doc; my patch for this is here:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
