Again on #definesClass: and #includesClass:
by Yuriy Tymchuk July 3, 2014

July 3, 2014

In environments we have two methods: #definesClass: and #includesClass:. They make sense for package environments, as one of them may include a class as it defines extension methods for it, but itâs not defining the class itself. Now #includesClass: is redefined in all environments, but #definesClass: is not redefined anywhere except for package environment. So for example ClassEnvironment says that it defines every class that itâs asked about. Should we redefine that method in each environment? I would say yes, but Iâm not familiar with RBâ¦Stuff philosophy. What do you think? Cheers. Uko

Pharo running with spur (work in process)
by Esteban Lorenzano July 3, 2014

July 3, 2014

Hi, Iâve been working on prepare Pharo to run with the new Spur VMâ¦ and finally this week Guille and I sit together and make a huge advance :) here a screenshot of pharo 4 running with spur: for more information, same image before migration, with a regular cogvm gives this numbers: '1297023432 bytecodes/sec; 161029354 sends/secâ, so that means that the tiny benchmarks run at 166% the speed of the old vmâ¦ Of course this is just one benchmark, but Iâm very impressed :) Now, it is still not usable but Iâm confident I can put a jenkins job to work very soon :) Esteban ps: before you start asking: Spur WILL NOT be available for Pharo3, it will be part of Pharo4.

New Cog VMs available
by Eliot Miranda July 3, 2014

July 3, 2014

...at http://www.mirandabanda.org/files/Cog/VM/VM.r3029/. I've taken down the 3021 and 3024 VMs as their LargeIntegers code was badly broken. That's fixed now. The major changes are that Spur now correctly handles forwarding in primitives invoked from machine code, and that sends to Characters have the expected performance. CogVM binaries as per VMMaker.oscog-eem.797/r3029 Fix mixup of old & young spaces in primitiveVMParameter, and comment some new parameters. Fix return types for positive[64/32]BitValueOf:. positive32BitValueOf: must answer a usqInt, positive64BitValueOf: must answer a usqLong. Use positiveMachineIntegerValueOf: to decode arg in primitiveNewWithArg and ensure positiveMachineIntegerValueOf: is inlined there-in. Spur: Fix inline cache for Characters in Spur. Existing code failed all machine code sends to characters, creating PICs at those send sites which failed back to the interpreter. Implement forwarder following on primitive failure for all primitive calls from machine code. Allow the JIT to not compile primitiveDoNamedPrimitiveWithArgs to avoid any potential complications. Have spur's fetchClassOfNonImm: answer nilObj for forwarders to avoid assert fails. Fix assert fails in updateStateOfSpouseContextForFrame:WithSP: and elsewhere with forwarders. 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 StackInterpreter>>actuallyFollowNecessaryForwardingInMethod:literalCount: so that it no longer corrupts the methodClassAssociation. 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. These changes allow Cog Spur to redefine Process and/or Semaphore and not hang. Fix sign and overflow issues in instantiating larger objects and determining the size of large instances. Fix some freeChunk accesses that used fetchPointer:ofObject:. Make sure forwarders have accurate slot counts, bumping it to 1 if it was zero. Plugins: Fix LargeIntegersPlugin>>isNormalized: for forwarders, no longer assuming that if its arg isn't a SmallInteger it must be a large integer. Squash an assert fail in lengthOf:format: on forwarders by using numSlotsOfAny:. Fix the shift for divide issues in the LargeIntegersPlugin. Change the SmartSyntaxPluginCodeGenerator to generate code that ifdefs out the remapOop:in: rigmarole on Spur. Windows: Set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the image header of the Windows executables to allow e.g. Spur to allocate more than 2Gb. Slang: Rip out the UseRightShiftForDivide optimization. It gets unsigned division wrong, and C compilers can and will optimize this correctly themselves. -- best, Eliot

Athens and StrikeFont ( again )
by Nicolai Hess July 2, 2014

July 2, 2014

If I take a fresh pharo image I always have to reenable FT fonts before doing any athens rendering with text (RMOD StrikeFont(Object)>>doesNotUnderstand: #getPreciseHeight). Ok, I know I have to open settings disable then enable FreeType and choose a FreeType font. But what exactly is the problem with Athens rendering and non FT fonts? Nicolai

AlignmentMorph class>>newRow and pinning Menus
by Nicolai Hess July 2, 2014

July 2, 2014

As you might know, pinning a Menu (like the WorldMenu) slightly changes the size of the menu. This was somehow caused by initialising AlignmentMorphs with an extent 1@1 in #newRow. I removed that line, th fix is in Pharo 40 059. (issue 13433 <https://pharo.fogbugz.com/default.asp?13433>). As the morph layout computation is pretty complex this may cause some unforeseen issues. just to be warned :) nicolai

Seeking help
by Janko Korelc July 2, 2014

July 2, 2014

Several days ago I was immersed in Pharo3.0 as this time things worked well. So, did include many packaeges in image up to Eye-watcer, than started to look what a repository is all about - so, was given offer to have some subdomain with my name and probably uploaded everything. Next time when I started my image from disk there was small progress bar - clearly something was updating itself or something and Eye-Watcher was in debuger window not understanding some message. Clearly had installed something unfinished or wrongly initialized. So, i deleted entire Pharo directory, and downloaded pharo, and same thing happend. Pretty nasty Huh, I am sorry if i ruined something on repository I am afraid of. Could you please tell me what is going on? Or in case i ruined repository how long does it take to fix it, please help! Thank You!
