It must be transfered in BINARY mode, even if it looks like a text file, to preserve the CR line ends. Mac users: This may have been caused by Stuffit Expander. To prevent the files above to be converted to Mac line ends when they are expanded, do this: Start the program, then from Preferences... in the File menu, choose the Cross Platform panel, then select "Never" and press OK. Then expand the compressed archive again. (Occasionally, the source code for a method may legitimately start with a non-alphabetic character -- for example, Behavior method #formalHeaderPartsFor:. In such rare cases, you can happily disregard this warning.)'!

Frank Shearar uploaded a new version of Tests to project The Trunk: http://source.squeak.org/trunk/Tests-fbs.244.mcz ==================== Summary ==================== Name: Tests-fbs.244 Author: fbs Time: 25 July 2013, 8:55:25.056 am UUID: c331e496-09f7-d844-b28c-9b30fe401874 Ancestors: Tests-fbs.243 SmalltalkImage current -> Smalltalk. =============== Diff against Tests-fbs.243 =============== Item was changed: Object subclass: #PrimCallControllerAbstract instanceVariableNames: 'treatedMethods logStream changeStatusOfFailedCallsFlag' classVariableNames: '' poolDictionaries: '' category: 'Tests-PrimCallController'! + !PrimCallControllerAbstract commentStamp: 'fbs 7/25/2013 07:16' prior: 0! - !PrimCallControllerAbstract commentStamp: 'nice 3/25/2010 23:02' prior: 0! A PrimCallController (PCC) serves for switching external prim calls (primitiveExternalCall) on and off: this is an abstract class, instantiate one of the subclasses PCCByLiterals and PCCByCompilation. External prim calls are used to access internal and external modules (plugins) as shown by + Smalltalk listLoadedModules. + Smalltalk listBuiltinModules. - SmalltalkImage current listLoadedModules. - SmalltalkImage current listBuiltinModules. Note: not loaded external modules (since they have not been called so far) are not shown by these methods. Highlight: dis/en-abling prims by a PCC works for both internal and external modules!! To help you choosing the right subclass, some properties are listed in the following table: Functionality/Property | PCCByLiterals PCCByCompilation ------------------------------------------------------------------------------------------------------ testing plugins | suited not suited permanent disabling of external prim calls | no yes ------------------------------------------------------------------------------------------------------ method changes visible in changeset | no yes enabling survives snapshot/compilation | yes yes disabling survives snapshot/compilation | no yes speed disabling | fast medium speed enabling | fast slow CompiledMethod pointer valid after en/dis-abling | yes no Important: Be careful with mixing the use of different PCCs!! PCCByLiterals does not see prims disabled by PCCByCompilation and vice versa. For playing around you should start with PCCByLiterals; use PCCByCompilation only, if you know what you are doing!! In protocols 'ui controlling', 'ui logging' and 'ui querying' (please look into this class) are the most important user interface methods. Thereafter the methods in 'ui testing' could be of interest. Useful expressions: Controlling: "Factorial example" | pcc tDisabled tEnabled tEnabled2 | pcc := PCCByLiterals new logStream: Transcript. "logStream set here for more info" pcc disableCallsIntoModule: 'LargeIntegers'. tDisabled := [1000 factorial] timeToRun. pcc enableDisabled. tEnabled := [1000 factorial] timeToRun. tEnabled2 := [1000 factorial] timeToRun. {tDisabled. tEnabled. tEnabled2} Note: You shouldn't switch off module 'LargeIntegers' for a longer time, since this slows down your system.
