04:25 <jhg_> fche jistone: for the halibut, I overengineered a parallel arbitrary unresolved kernel module symbol lookup script. it generates the list with nm, then checks each entry (in parallel) for probability in kernel, then reports only those which are. https://gist.github.com/jhgorse/e4b957e970efacd6051be2caeaaf4542

04:37 <jhg_> and I messed something up.

04:52 <jhg_> fixed. needed the wait to sequentially do the pids. =)

04:53 <jhg_> night!

08:02 <Minnozz> is it possible to do conditional compilation on the value of $1?

08:04 <Minnozz> I want to include or exclude an entire probe based on the value of $1

08:21 <Minnozz> err, I meant @1

08:24 <Minnozz> ah, %( @1 == ... %? %) works

16:42 <jistone> jhg_, note you don't necessarily need to figure out probe-ability ahead of time

16:43 <jistone> ("probability" confused me at first, like you were talking about statistics)

16:43 <jistone> jhg_, you can write each possible function with a '?' after in a script, to mark it optional in case it can't be probed

16:44 <jistone> probe kernel.function("foo")? , kernel.function("bar"), ... { println(pp()) }

17:10 <jhg_> jistone: it was late, I wasn't thinking clearly. probability vs probe-ability. heh...

17:11 <jhg_> though now I have a semi-parallel batch script

17:13 <jhg_> I updated the comment in the script with your note.

17:20 <jistone> jhg_, you could also chain those in your listing tests, which should perform better than many separate stap -l invocations

17:20 <jistone> stap -l 'kernel.function("foo"),kernel.function("bar"),kernel.function("schedule")'

17:21 <jhg_> aha! I had been wondering about that... had not seen that before

17:21 <jistone> or even: stap -l 'kernel.{function("foo"),function("bar"),function("schedule")}'

17:21 <jistone> we have limited brace expansion

17:22 <jistone> then you just need to split it up enough that you don't exceed command-line length limits
