I just found it odd, that when looking at the site with the docs or source I got a warning about Adware. Nothing else. Alex

Environments
by Chris Cunnington 26 Jun '12

26 Jun '12

This is a nice surprise. My only knowledge with Environments came from Germán's work in the GSoC 2010, as demonstrated here: http://www.youtube.com/watch?v=n4I7fSVNX2A Your work is quite different. No Environments added as classes in a browser. I remember importing code into an Environment being a showstopper. You've imported Seaside. I guess you could have thirty Environments with thirty people doing the HelloWorld demo with #renderContentOn:. One image serving thirty people over the wire. I imagine that the main concern is collisions and not security. But I guess if you're importing Smalltalk globals into Environment>>lookup, then you can mask out the classes you don't want an Environment to be able to access. Say, remove FileDirectory and FileStream, so that those hypothetical Seaside users couldn't explore the file system and send the results back to the browser. Cool stuff. Chris

Source RPM for Squeak-4.4.7.2357
by Ajay Garg 24 Jun '12

24 Jun '12

Hi all. I have created a SRC RPM for Squeak-4.4.7.2357. Kindly let me know, where I may upload it (I wonder that attaching the src-rpm in this mail, might cause the message rejection). The main files of interest are :: a) squeak-vm.spec b) Mpeg3Plugin.patch (Required to play MP3s) Thanks to Dr. Bert Freudenberg for the catch and the fix !! c) ARMbuildFailFix.patch (Required to get the build done on ARM). Details of patches are included in the corresponding patches themselves. All that is needed to be done is """rpmbuild -ba /path/to/rpmbuild/SPECS/squeak-vm.spec""" and it will include compilation + packaging + cleanup (on the build machine). Thanks and Regards, Ajay

I don't have time to think about this carefully right now, but it looks like this is covering up a serious bug in the exception system. Thoughts? -- best, Eliot

Progress changes break VMMaker
by Eliot Miranda 23 Jun '12

23 Jun '12

Hi All, Hi Chris, something in the changes to ProcessInitiationException done in ToolBuilder-Kernel-cmm.48/49/52 breaks the VMMaker. i.e. the following prints nil 5 times to the Transcript instead of printing #caught 5 times. ['Progressing' displayProgressFrom: 1 to: 5 during: [:bar| 1 to: 5 do: [:i| Transcript cr; print: (Notification new tag: #getVMMaker; signal); flush. bar value: i]]] on: Notification do:[:ex| ex tag == #getVMMaker ifTrue: [ex resume: #caught] ifFalse: [ex pass]] Any help in fixing this appreciated! Interestingly in the following count is 1 | count | count := 0. ['Progressing' displayProgressFrom: 1 to: 5 during: [:bar| 1 to: 5 do: [:i| Transcript cr; print: (Notification new tag: #getVMMaker; signal); flush. bar value: i]]] on: Notification do:[:ex| count := count + 1. ex tag == #getVMMaker ifTrue: [ex resume: #caught] ifFalse: [ex pass]]. count 1 -- best, Eliot
