Quoting Robert Watson <rwatson@FreeBSD.org> (from Tue, 21 Nov 2006 11:55:37 +0000 (GMT)): > Anyone who wants to start looking at a new API should make sure they > look at ptrace() and procfs across a range of platforms, and also look > at Mach task ports and what they offer. One of the things we really > can't do well with ptrace() today is inspect kernel state for a running > process -- things like the VM layout, etc. We should make sure any > next generation system allows this, because that feature alone is the > reason why I sometimes mount procfs. :-) Can you please elaborate what features you have in mind which DTrace isn't able to deliver?
