Debugging multithreaded program using Eclipse/Pydev

I am back against the wall trying to migrate my multithreaded
application from Python 2.3 to 2.5. The part of the code that's
failing has to do with queues (2.3 queues and 2.5 queues are not the
same). Since WingIDE doesn't support multithread debugging (they've
been saying that one day they might support that - and that was 2003),
I am starting to look for alternatives.
>From what I can gather, it appears the only *real* option I have is to
debug under Eclipse/Pydev. I did a google search of this newsgroup
and didn't turn up too many hits. Before I invest the time to learn
Eclipse/Pydev, I like to hear from somebody that have gone this path.
Have you been successful in using Eclipse/Pydev to debug multi-
threaded Python applications? Is so, what was the learning curve like
to you?

Thanks,

The alpha release of Wing IDE (3.0.0-a1) does in fact, support
multithread debugging. It is an alpha release but so far, I'm quite
satisfied with it.

That's nice to know. May be I can get on their alpha list.

I use pydev extensively for all my Python related work. And I really love
it.

The good part about Eclipse/PyDev is that (if you are an Eclipse user)
you'll have to learn only a single IDE for all your programming works in
most of the languages. The interface, the shortcut keys to step, all are
the same across all languages that you use in Eclipse.

As for PyDev, it works very good with Eclipse.
Be it code-completion or thread debugging, all is supported. For
multithreaded applications, in PyDev, you'll see all the threads listed.
Then you can use each thread and proceed with debugging the code.

Learning Eclipse might take some time but that's worth it.

HTH,
Ritesh

ActiveState Komodo can also do multithreaded debugging.

And if all else fails, you can insert:

import pdb
pdb.set_trace()

in your code and that way you will break on any thread.

Currently I am using pydev myself, having gone through WingIDE and Komodo.

I ran the alpha version of Wing. So far, it appears to do a fine job
in debugging multi-threaded applications.

And yes, I fixed my bug within 5 minutes.

Hi, this is actually a question to those of us who use Eclipse and Pydev as their main Python developing environment. As i use Eclipse (3.3 Europa) only for Python and i have nothing to do with Java, is there a way to disable/uninstall some Java-specific stuff and make the environment actually more snappy ?? thanks for any help

Hi, i am using Eclipse (Platform Runtime binary) with PyDev and i was wondering if someone can help me with this: 1.

So, i press F9, Eclipse starts, Debug perspective opens and i can use the debugger just fine. But when the app terminates, how can i tell Eclipse to switch...
