Meeting 28 April 2016

Mark Johnston, Shrikanth Kamath, Erin MacNeil, George Neville-Neil

• DTrace man pages don't show up in the on-line version

• George mentions the new random() function that's not yet shared outside CADETS.

• Enabling the destructive action using a copyout may or may not work.

• Static functions are not showing their arguments properly. Mark says that this may be compiler related.

• Tracing a 32 bit application on a 64 bit system causes the application to crash. Mark says he knows about this and will try to track it down before 11.0

• Add a bsd:::: provider and move mbuf under that.

• We discussed the performance of aggregators but it seems that there isn't much to do immediately about that.

• Mark has measured his new SDT patch and it improves performance by 2% which matters because turning on KDTRACE does impact performance by about 2%. He will work to get this in soon.

• Mark has been looking at the conversion of CTF tools from Joyent which can deal with CTF and DWARF more naturally.

• Bryan Cantril has announced (on Twitter) a DTraceConf on May 25 but there are as yet no details.
