The fixes are in Kernel-eem.468 and Kernel-eem.469. Its probably best to load Kernel-eem.468 and then Kernel-eem.469 rather than just Kernel-eem.469 because the system will crash if the fixes come i in the wrong order. Kernel-eem.468 also fixes restart in blocks in the debugger (its the same issue; forgetting to initialize the context with any arguments and copied values; local temps get initialized by explicit pushNil bytecodes). thanks for the test case Rob! best Eliot P.S.

[Pharo-project] ConfigurationOfOSProcess updated

by David T. Lewis

I have made a few updates to OSProcess and CommandShell that I hope will be useful for Pharo: On SqueakSource, I repackaged both OSProcess and CommandShell into finer-grained package naming. Tests-OSProcess and Tests-CommandShell become OSProcess-Tests and CommandShell-Tests to avoid package name conflicts with Pharo and Squeak. The rest of the former OSProcess and CommandShell are split out into sub-packages to support this, and also to make it possible avoid loading portions of the package that are not required (e.g. in Pharo, do not load MVC portions of CommandShell). I updated ConfigurationOfOSProcess in SqS/MetacelloRespository to load OSProcess from the new package structure. This will also load a number of updates that make things work properly on Pharo. On a Unix/Linux platform, all tests should be green (I am not sure of the status on OS X). I have not yet tried to do a ConfigurationOfCommandShell, but if you use OSProcess and want to also use PipeableOSProcess from the CommandShell package (but are not interested in the rest of CommandShell), you can load ConfigurationOfOSProcess, then use a Monticello browser to load just package CommandShell-Piping from the CommandShell project on SqueakSource. This is my first attempt to do anything with Metacello, so any fixes or corrections will be appreciated. Miguel Cob originally created the ConfigurationOfOSProcess, so thanks to Miguel for doing this. Dave

I tend to run into applications where it makes sense to have both. The big blobs that do not change a lot (photos, documents) in the cloud, the objects with behaviour in the oodb. Stephan

I did created a new project in Squeaksource called UIBuilder, where the people could access and modify without problems. Then CLFramework now is only for me, as backup copy and probes.
