Oops, please ignore my other reply to this post. I didn't grab the
start_new_thread() result, but instead grabbed the result of
thread.get_ident() and stored that. The docs claim this is not a value
that necessarily relates to anything in the outside world ("Return the
`thread identifier' of the current thread. This is a nonzero integer.
Its value has no direct meaning; it is intended as a magic cookie ...")
so if it happens to match the thread id from the OS's point of view,
it's an implementation detail you couldn't rely on.
So the general idea I gave might be useful, but I don't know precisely
how to do exactly what you are asking. Sorry.

I believe the underlying call to thread.start_new_thread() already returns the thread identifier that you want, but I haven't tried it recently and don't recall for sure. To use this, however, you'd have to patch the source or subclass, as I mentioned. I did this once and stored the result in the Thread as an attribute called .threadId and don't recall any problem using that. -Peter -- http://mail.python.org/mailman/listinfo/python-list

Thank you for your info. Now I have read that a simple call os.getpid() returned the linux identifier of the thread in latest python versions, but I'm using Python 2.3 and 2.4 and this call returns always the same id I only want to take the pid of the thread but isn't as easier as it seems. -- View this message in context: http://www.nabble.com/Thread-Dump-of-a-python-process-t1089322.html#a2868401 Sent from the Python - python-list forum at Nabble.com. -- http://mail.python.org/mailman/listinfo/python-list

You could easily subclass Thread to provide your own .start() which does that, and perhaps modify __repr__ to output that instead of the id() value. Check the source in threading.py if this approach sounds useful. -Peter -- http://mail.python.org/mailman/listinfo/python-list
Thread Dump of a python process
Hi, I would to know if there're some way to have a dump of all the threads started by a python process. I want to see the TID corresponding of each thread because I need them to get the CPU time of each thread by the command top.
