Python Debugger

[Lothar Scholz]

Is there any python debugger that can

1) be used remotely
2) can handle multiple threads

I checked Eric, IDLE and Wing-IDE. None of them can do this.
Any other recommendations?

What do you mean by remotely? Debug a program running on a server
from a remote PC? Or telnet to the server and display the debug
session on the PC?

If the latter then the standard pdb module works just fine.
2) can handle multiple threads

Never tried that one, although pdb might work...

Hapdebugger claims all this (but I've never really tried it).

No it does not.

For this, we use WingIDE, a commercial IDE for Python.

2) can handle multiple threads

When you mean a debugger that can set breakpoints in any thread,
analyse the state of any thread etc, then this is unlikely.

Python maintains the debugging hook in a thread specific data structure.
The available API functions can only access the debugging hook
in the own thread but not in a foreign thread.

This implies that unless the start of a thread is customized
(such that the debugging hook is immediately set on thread start)
it is very difficult to debug a foreign thread (without
a specialized C extension using internal implementation details of
Pythons thread implementation).

I thought I saw one or two checkins by Jeremy Hylton in this regard. I
don't recall if it was before or after the 2.3 release, but I'm pretty sure
there's more in there now (in CVS at least) than there was in 2.2.

Successfully done that with WingIDE (server on Solaris, debug from PC)

Debugging multi-thread python apps is being discussed in another topic.

Don't use telnet. man ssh ; man sshd
