I know that, but I was just pointing out that if I change the base class and commit while your code is loaded, I publish unwillingly your trait. So, when your code is loaded I have to be careful to first remove the trait and only afterwards publish my change. This is a severe limitation and it stems from the Trait definition being tightly coupled with the class definition (both in the model and in the browser). Cheers, Doru >> 2.

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

Thanks ron for the offer as you can see in http://code.google.com/p/pharo/issues/detail?id=1884 we got a bit burned by the status of the network code. So if you can try some expressions with the latest unstable 1.1 it would help us to know if we should apply the rollback fix.

I would have love to give you a real answer. I'm doing pharo because I want a beautiful system from which people (and me) can learn. I want to be enlightened by beautiful code.

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.

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

by Mariano Martinez Peck

Hi guys. No, it doesn't work for me neither. I have checked in Pharo 1.0 and 1.1 with both: useOldNetwork as true and false. I have debugged a little the: Socket ping: 'localhost' And the problem I found is that after calling "connectNonBlockingTo: hostAddress port: port" self primSocketConnectionStatus: socketHandle. should answer something different thanUnconnected ( 0 ), like WaitingForConnection (1) or Connected (2) check Socket class >> initialize So....I should see in VM side why primSocketConnectionStatus: socketHandle. may be returning 0 (unconnected). Now...if I ping Socket ping: 'www.google.com' The result is different as I get WaitingForConnection (1) instead of 0....but it loops forever as I always get 1 and never 2....see the loop [(status = WaitingForConnection) and: [(msecsEllapsed := Time millisecondsSince: startTime) < msecsDelta]] whileTrue: [ semaphore waitTimeoutMSecs: msecsDelta - msecsEllapsed. status := self primSocketConnectionStatus: socketHandle]. in the method waitForConnectionFor: timeout ifTimedOut: timeoutBlock I will continue to check, but my knowledge in this area is almost nil.
