Excellent, “fork parent, auto” works perfectly. Thanks.

Doing this at the prompt seems to do it.

>fork parent, auto

“By default the debugger will pause (break) the debuggee when it identifies that a fork is about to be attempted”

The above statement implies there’s a way to turn that behavior off. I’d be elated to hear that there is a way to do this. Is there?

OK, I’ve worked around the issue by using the info from the Embedded Debugging link on the right, e.g.:

pid = os.fork()
if pid > 0:
os.waitpid(pid, 0)
else:
if os.environ.get(’DEBUG_RPDB2′):
sys.path.append(’/var/tmp/bin’)
import rpdb2;
rpdb2.start_embedded_debugger(’test’, fAllowRemote = True)
# rest of child process follows here

No joy with that. Client is WinXP, server is CentOS release 5 (Final). Both on Python 2.6. Any ideas welcome.

Just after entering ‘fork child’ and resuming, in the server I get:
Exception in thread __worker_target:
Traceback (most recent call last):
File “/usr/local/lib/python2.6/threading.py”, line 525, in __bootstrap_inner

raise RuntimeError(”cannot release un-aquired lock”)
RuntimeError: cannot release un-aquired lock

Am going to try putting a catch block around that stmt.
