I am currently working on adding DTrace probes we have for Memcached 1.2.5 to the new binary protocol in 1.3 branch. The problem I am facing is that I should have had a new variable into the probe. When we added the probes, all memcached keys would be zeroterminated ascii strings, but in the binary protocol it may not be zero-terminated.
So what do I do? According to http://src.opensolaris.org/source/xref/webstack/memcached-incubator/trunk/server/memcached_dtrace.d#270 I would guess that I can modify the probes to contain the length field? Or should I go ahead and create another set of probes for the binary protocol? Cheers, Trond
