Flushing the VM method cache?

by Joachim Geidel

Hello all, The software I am working on generates classes on the fly, and discards those classes when they are no longer needed. The class library is cross-platform, i.e. it exists for Dolphin and VisualWorks, and I am currently porting it to Pharo. In Dolphin, it is necessary to flush the VM's method cache after discarding all the dynamically generated classes, because the method cache holds references to the classes which prevent them from being garbage collected. For VisualWorks, I have adopted this, although I am not quite sure if it's actually needed there. In the Pharo 1.0 image, I haven't found a method for flushing the VM's method cache in one go, there only seems to be Behavior>>flushCache. What I would like to know is: - Does the VM method cache of the Squeak VM hold references to classes which prevent an obsolete class from being garbage collected? If this is not the case, I don't need to flush anything. - If flushing the cache is advisable, is Behavior>>flushCache the only way to do this? I would have to pick up all the obsolete classes and iterate over them in that case. Thanks in advance! Joachim Geidel

Re: [Pharo-users] Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

by RickT

Thanks for the great response! I am not only a newbie to Smalltalk but also to any sort of network programming. I guess my exposure to 'ping' on other systems was always the ICMP flavor; so I was surprised by this implementation. As Mariano pointed out, the source code in Pharo1.0 indicates port 7: tcpPort := 7. "7 = echo port, 13 = time port, 19 = character generator port" It seems to me that a ping: method should be the ICMP kind, and a ping:port: method should be for the TCP variety. I presume an echo server could be run on ports other than 7 or 10, depending on preference. So maybe the port should be designated by the caller, and not hard-coded into the class method. I see the other reasoning from your response. Thanks again for clarifying this (and educating me). -- View this message in context: http://forum.world.st/Newbie-Does-Socket-ping-addr-work-in-Pharo3-11-8-tp22… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

So you can try the method #pingPortsOn: hostName which does: pingPortsOn: hostName "Attempt to connect to a set of well-known sockets on the given host, and answer the names of the available ports."

The DOS and Unix ping utilities send an *ICMP* echo request packet and expects an echo response. This is normally handled by the protocol stack itself. The Pharo #ping: method makes a *TCP* connection to port 10 (echo service) on the destination machine. If there's no server listening on that port, the connection will fail.

Accentuate Characters

by Adrien BARREAU

Hello, I want to compose accentuate character in Pharo, but I don't know how I can do that. I saw in Visual Works I can write this kind of things : $e composeDiacritical: (Character diacriticalNamed: #acute). That returns $Ã©. But, I don't find a way to do that in Pharo. Does somebody have an idea ? :) A.B. _________________________________________________________________ Vous voulez regarder la TV directement depuis votre PC ?

Re: [Pharo-users] Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

Hi Mariano, Your debugging efforts match what I was finding. I was originally having problems with Socket>>connect: , which kept failing. So I thought I would just try the most minimal thing, ping. There may be problems with Socket class in general. Thanks again. -- View this message in context: http://forum.world.st/Newbie-Does-Socket-ping-addr-work-in-Pharo3-11-8-tp22… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

which is cool because you can learn fast :) I like to try to answer questions because this is a good way to learn. Thanks for having this cool attitude too. Stef > Hi guys. No, it doesn't work for me neither.
