Re: [Pharo-users] Gathering statistics on messages sent to an object

by Denis Kudriashov

Hi Alistair. Do you know that you are able to count any message send? (not only external). For this you need prevent meta recursion. Now inside message processing you do: aMessage sendTo: anObject which produces another intercepting message #perform:withArguments which repeats original message send. Fortunately Ghost handles such kind of meta recursion and there is no infinite loop here: any self-sends are ignored in such cases. If you want intercept any message try following code: ExternalSendTrace>>send: aMessage to: anObject | method | announcer announce: (ExternalSendAnnouncement message: aMessage trace: self). method := anObject class lookupSelector: aMessage selector. ^GHMetaMessages executeWith: anObject andArguments: aMessage arguments method: method In that case we lookup and execute method by using mirror primitive which not sends any message to object. For example: rect := 10@30 corner: 100@300. trace := ExternalSendStats logStatsFor: rect. rect area. trace stats. "a Dictionary(#area->1 #height->1 #width->1 )" Best regards, Denis 2017-04-24 14:43 GMT+02:00 Alistair Grant <akgrant0710(a)gmail.com>: > If you subscribe to pharo-dev you will have seen that I've been looking > at the primitives used in DiskStore. > > As part of that investigation I wanted to get an idea of which messages > are typically sent to DiskStore and how often. > > Denis Kudriashov provided a neat package that implements a "halt on > next object call".

Gathering statistics on messages sent to an object

by Alistair Grant

If you subscribe to pharo-dev you will have seen that I've been looking at the primitives used in DiskStore. As part of that investigation I wanted to get an idea of which messages are typically sent to DiskStore and how often. Denis Kudriashov provided a neat package that implements a "halt on next object call". I've been wanting to play with the package for a while and decided this was a good opportunity. I've extended that package to keep count of how many times messages are sent to a target object, e.g.: | point trace | point := 2@3. trace := ExternalSendStats logStatsFor: point. point x; y; angle; x. trace stats. "a Dictionary( #angle->1 #x->2 #y->1 )" The package is probably too simplistic, and there's bound to be other ways to do this, but it met my immediate needs and gave me a chance to try out the Ghost package. I'll extend it if and when I need to. Many thanks to Denis for making the Ghost package available, and hopefully this is useful for someone, or at least triggers some new ideas. Denis' original article is at: http://dionisiydk.blogspot.cz/2016/04/halt-next-object-call.html The extensions can be installed with: Metacello new baseline: 'AkgGhost'; repository: 'github://akgrant43/akg-ghost:master/mc'; load Cheers, Alistair

Re: [Pharo-users] PMMatrix vs Matrix

by Serge Stinckwich

Yes this what I was going to answer as well. Matrix in Pharo does not implement the usual mathematical operators like PMMatrix. Maybe should be rename as Array2D in order to avoid confusion in the future.
