dtrace discuss - Sep 2007 - DTrace in S10U4 - new features

Hello,

I have just read the
http://blogs.sun.com/katohisa/entry/solaris_10_8_07_dtrace
blog and found that there is new functions, ''ufunc/ucaller''. I
couldn''t
find any _documentation_ with its description.
Could anybody sched some light on why is that ?
Is there any up-to-date DTrace manual for S10U4 ?

Regards

Yes, apologies about this. The documentation has fallen a bit behind
the implementation so most (if not all) of the features that have
arrived since S10 released are not in there.

Fortunately, Bryan gives some useful examples in the original bug
reports for these new features which should answer your question.

For ufunc:

http://bugs.opensolaris.org/view_bug.do?bug_id=6311947

For ucaller:

http://bugs.opensolaris.org/view_bug.do?bug_id=6315034


I actually did a presentation at last nights London OpenSolaris User
Group meeting which went through some of the features that have been
added since s10 released. I''ll try and put the slides up on my blog
sometime. There''s nothing in the slides that you can''t find on
the web but it''s all in one place.

Let me know if the above doesn''t answer your question.

Jon.

Thank you, Jon, for the ufunc/ucaller basic explanation.
But of course it would be good to have more systematic
("manual-ed") description. :-)

In general I miss very much an easy way of checking when does some feature
from Nevada (assuming Nevada is the newest bits) gets into
Solaris 10/SXDE/OpenSolaris. Something like:
feature A from NevadaXX	is in SXDE* and in OpenSolaris* and in Solaris 10U*
feature B from NevadaYY is in SXDE* and in OpenSolaris* and in Solaris 10U*
etc 



Besides is there any schedule/plan of "refreshing" DTrace manual ?

The DTrace Change Log kind of handles this but it needs to be brought
up to date:

> Besides is there any schedule/plan of "refreshing" DTrace manual 
I''m not aware of one. It is something that we need to address though.
