Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass

by Larry White

I was able to replicate with a clean version of the Seaside 3.0.6 One Click download by executing Stream #basicNew in a workspace. It did work a couple times ok using "do it" from the menu, but seems to lock pretty regularly using print or explore keyboard shortcuts. thanks.

Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass

by Larry White

I can do it with control-P (print) in the Workspace. I just did it with a single try, though sometimes it takes more than one. Speed isn't an issue, I can wait 10 minutes and see it happen sometimes.. I have to take a break now, but when I get a few minutes, I'll try again with a fresh install of the latest Seaside one-click for the mac. thanks.

Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass

by Schwab,Wilhelm K

I just tried to hang 1.1.1 (using a traditional linux vm) and a 1.4 image with a Cog vm (also linux). No problems, but I do have questions that might be important to others trying to reproduce it: (1) how fast do you do this? (2) do you inspect the instances, or just let them get gc'd immediately?

I can do it with Stream basicNew. but I have to invoke it twice. The first time it works ok.

Re: [Pharo-project] [Seaside] SqueakSource

by Tudor Girba

Hi Sebastian, First, squeaksource is free and it is hosted for free, too (as the main page says, squeaksource.com is hosted free of charge by the Software Composition Group, University of Bern). Second, it is old: it dates from 2004: http://www.squeaksource.com/ss.html This was a great piece of infrastructure built by some cool guys, but now it shows its age: http://www.squeaksource.com/ss.html Please do not blame neither the authors, nor the current people that are still trying to keep it alive: basically, a couple of brave PhD students that maintain the infrastructure (not the code) in their spare time (namely, Jorge Ressia and Fabrizio Perin). There is at least one other option that should be more stable: http://ss3.gemstone.com/ And of course, in the meantime, we are all waiting for: http://www.smalltalkhub.com/ So, all in all, please refrain from these kinds of remarks.

Yeah I would really love to see this. maybe with a fixed lookup chain 1. Settings from the Image directory/startup.st 2. Settings from ~/.pharo/$VERSION/startup.st 3. Settings from ~/.pharo/startup.st cami
