[issue4111] Add DTrace probes
Ted Leung <[EMAIL PROTECTED]> added the comment: And courtesy of Philip Jenvey, here I am. I would *really* like to work to help make this happen. Laszlo Peter at Sun has been doing the ports of Python on Solaris, but we are not up to 2.6 just yet. I'm attaching a pointer to his patches against 2.5: http://src.opensolaris.org/source/xref/jds/spec-files/trunk/patches/Python25-07-dtrace.diff These patches include John Levon's ustack provider, which if you care about DTrace and Python, you want to have. I've also had some conversations with people at Apple, and they have agreed that they will pull DTrace probes from python.org if they got in there. That would solve the diverging probe problem. I'd love to have a discussion about DTrace probe futures for CPython -- probably on python-dev. -- nosy: +twleung ___ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4111> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4111] Add DTrace probes
Ted Leung added the comment: I didn't run auto(re)conf. After I did that, all was well. However, the ustack provider doesn't appear to be working correctly. I tried running the py_profile.d from the DTrace toolkit, and it doesn't show any stack traces, and when the script starts up it says cc1: warning: /dev/fd/5 is shorter than expected The basic function entry/exit probes appear to be working. John +nosy'ed himself, so perhaps he'll have some insight?
