Welcome new Squeak trunk developer Karl Ramberg
by David T. Lewis 04 Jul '14

04 Jul '14

Hi Karl, I asked the Squeak Oversight Board to add you as a Squeak trunk committer, and the motion was unanimously approved at today's board meeting. You are now a member of the Core Developers group on source.squeak.org, so you can commit directly to trunk, or use the web interface to move your packages from inbox to trunk. Thank you for your contributions! Dave, on behalf of the board

New Cog VMs available...
by Eliot Miranda 04 Jul '14

04 Jul '14

at http://www.mirandabanda.org/files/Cog/VM/VM.r3024/. I had *forgotten* to implement following forwarders on primitive failure in machine code primitives, hence Cog Spur was badly broken. It's now a little bit better, but I still need to implement this for named primitives. Real soon now I hope... CogVM source as per VMMaker.oscog-eem.791/r3024 Implement following forwarders on primitive failure in machine code interpreter primitives (still have to implement this in sideways calls of named primitives). Allow the JIT to not compile primitiveDoNamedPrimitiveWithArgs to avoid any potential complications. Rewrite all the semaphore installing primitives to fail if the semaphore arg is neither a semaphore or nil instead of assuming if its not a semaphore it must be nil, so as to fail and retry when semaphores are forwarded (as they are when Semaphore is redefined). Implement isSemaphoreOop:/Obj: in the object memories to abstract away the code. Base Spur's on the class index of splObj: ClassSemaphore, avoiding the table lookup to derive the class. Make checkForEventsMayContextSwitch: treat all its semaphores consistently. Have spur's fetchClassOfNonImm: answer nilObj for forwarders to avoid assert fails. On Spur add read barriers to primitiveSuspend and synchronousSignal:'s myList access, because the process list manipulation routines do no checking. Add assert checks for forwarders in the process list manipulation routines. Fix slip in StackInterpreter>>actuallyFollowNecessaryForwardingInMethod:literalCount: that corrupts the methodClassAssociation. Abstract out the call machinery from compileTrampolineFor:numArgs:arg:arg:arg:- arg:saveRegs:pushLinkReg:resultReg: so it can be used by maybeCompileRetry:onPrimitiveFail: in implementing following forwarders on primitive failure in machine code, and the Open PIC miss call. Have bytecodePCFor:cogMethod:startBcpc: map any pc before the stackCheckOffset to the initialPC, which applies to primitives in progress. Fix assert fails in updateStateOfSpouseContextForFrame:WithSP: and elsewhere with forwarders. LargeIntegers Plugin: Fix a latent signed shift bug in cDigitSub:len:with:len:into: caused by VMMaker.oscog-eem.785's eliminating the divide-via-shift optimization. These changes allow Cog Spur to redefine Process and/or Semaphore and not hang. -- best, Eliot

SMServer beta update
by Chris Cunnington 04 Jul '14

04 Jul '14

Nothing new to see this week. I'm working on forms for new objects such as account (aka the Register/Join page), package, and release. I'm adding form validation as well. They should be ready next week. Chris

Software Freedom Conservancy report
by tim Rowledge 03 Jul '14

03 Jul '14

Each year we’re asked to report back to the SFC on what we’ve done. This is our current list to cover march ’13 up to march ’14; it is supposed to be concise and we may already be beyond that but if there is anything really important that needs to be added, speak up very soon. - Squeak release 4.5 with the initial alpha implementation of Environments, a new name space system - Jenkins-based automated builds and testing of the Squeak image for continuous integration and testing. - RaspberryPi optimised and improved 'Scratch' system released (see http://www.raspberrypi.org/archives/5742) and featured at Smalltalk Industry Council '13 in Phoenix, and at Think'13 in Santa Cruz. - 'State of Squeak' talk at FOSDEM '13 in Brussels ( http://tinyurl.com/p2ko4pe) - New memory system development to further improve on the performance of the Cog VM. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim I'm so skeptical that I'm not sure I'm really a skeptic

MCMcmUpdater provides utility methods for updating Monticello packages from Monticello configurations. When Monticello configurations are stored in a repository (or repositories), MCMcmUpdater acts as an update stream. It first ensures that each configuration map has been loaded in sequence, then updates the last configuration map to the most recent version for each specified package, and finally loads these versions to produce a fully updated configuration. Currently if a set of packages are unloaded from the image, using this class to reload them may cause problems, depending on what dependencies those classes have. Success is not assured. Removing packages via SmalltalkImage>>unloadAllKnownPackages will be successful, it flags the packages removed so that they are not loaded by this utility. If you wish to not have MCMcmUpdater update packages, there are two ways to handle this: 1) To have MCMcmUpdater not update any packages not currently in the image set the UpdateMissingPackages preference to false: MCMcmUpdater updateMissingPackages: false Note that any new packages added to the repositories will not be picked up when this is turned off. 2) To have MCMcmUpdater not update a specific package, evaluate MCMcmUpdater disableUpdatesOfPackage: <packageName> Class Variables definitions: DefaultUpdateURL - String: the URL that will be checked by default for updates. This would be set for a common standard location to check. LastUpdateMap - Dictionary of Integer: version number of the last loaded update map per repository. Keeps track of the last configuration map, so that the utility will not have to run through the full history in the repositories each time you ask to update. SkipPackages - Set of Strings: names of packages to not update in MCMcmUpdater (empty by default). UpdateMissingPackages - Boolean: if true (default), new packages in the update config map will be loaded unless they are in SkipPackages. If false, packages not currently loaded in the image will not be loaded by MCMcmUpdater. (This can be dangerous if packages are split - use at your own risk). !

Surely this should be a String of some sort also? Any objections if I implement this as such? -- best, Eliot

This is an indicator of a problem. Hiding it won't help getting it fixed. There are no other references to SystemReporter (even though there's another menu item in the docking bar which brings up SystemReporter itself), because the other methods look up the class by name. It would be great to unify the three different methods, and make them work even if the current UIManager is not Morphic. The latter requires the extension of UIManager though...
