RPackage classes name
by Franck Warlouzet July 19, 2015

July 19, 2015

Hello, Currently I am working on groups in Nautilus, and I am actually reimplementing them because I could not just fix them (There are a lot of bugs which make them almost unusable in practice), it is too complicated for nothing. Doing this I somehow have to use RPackage announcements and I am a little bit confused by their name. When you remove a package, an announcement RPackageUnregistered is raised, but I do not know if there is a difference with RPackageRemoved (which by the way does not exist, but I was expecting a name like that). What is this registration thing ? There is no RPackageRegistered but there is RPackageCreated. So I am confused. Does someone know if I should create an announcement RPackageRemoved or rename RPackageCreated into RPackageRegistered ? It does not seem consistent and so it is confusing. Or can someone explain to me the notion of registration for the RPackages ? Thanks, Franck

New Cog VMs available
by Eliot Miranda July 19, 2015

July 19, 2015

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3410 Note that there's a functional 64-bit Spur Linux StackInterpreter included with these VMs and a 64-bit image to test at http://mirandabanda.org/files/Cog/SpurImages. CogVM binaries as per VMMaker.oscog-eem.1427/r3410 General: Implement a machine code perform:[with:]* primitive. Eliminate the duplication of SimpleStackBasedCogit/StackToRegisterMappingCogit>>compileOpenPIC:numArgs: now that we have dead code elimination enabled. Change the type of the event buffer from int[8] to long[8], along with the matching event typedefs in sq.h (fixes 64-bit SPur issues). Add a fence before reading checkSignalRequests and useTideA in doSignalExternalSemaphores. ARM Include the Alien support in the Squeak ARM VMs now that it works to a fair extent in Newspeak. ARM Cogits: Use __aeabit_idivmod to implement machine code div/mod primitives on ARM. 64-bit Spur Fix at least one set of 64-bit issues caused by Slang. In particular the integerObjectOf: code resulted in (objectMemory integerObjectOf: MillisecondClockMask) evaluating to the -1 object, instead of the 16r1FFFFFFF object, which was the cause of the initially nresponsive 64-bit image on the real VM. Newspeak: Compile Newspeak self and super sends as clean sends as well. Slower in monomorphic case but net win for the larger benchmarks, presumably because it avoids I-cache flushes in the polymorphic case. Also means implementing polymorphic caches for clean sends will benefit all non-ordinary sends. DeltaBlue +8.2% Splay +7.6% ParserCombinators +4.7% Richards +0.5% SlotRead (replaced with self send) -17.6% Spill ReceiverResultReg before runtime call to fix pushEnclosingObject on ARM. (ReceiverResultReg is edx/caller-saved on IA32 but r7/callee-saved on ARM.) Fix some primitiveFail[For:] calls in potential mirror primitives that did not return after falure, and could hence continue to do damage after detecting a failure condition. Fix the 64-bit Newspeak builds' plugins.ext Integrate Ryan's code for ARM call-out and callback support in the Alien plugin. Implement the relevant implicitReceiveCacheAt: for the ARM Cogits. ThreadedFFIPlugin: Allow ffiCreateIntegralResultOop:ofAtomicType:in: to be inlined. Reduce the number of tests leading to the common case of an integral return in ffiCalloutTo:SpecOnStack:in: etc. Refactor the remapOop:in: idiom up into InterpreterPlugin and use it in the ThreadedFFIPlugin. Hence avoid unnecessary push/popRemappableOop calls. -- _,,,^..^,,,_ best, Eliot

Re: [Pharo-dev] millisecondClockValue
by Eliot Miranda July 19, 2015

July 19, 2015

Hi Alain, that's actually a good question. The issue is whether the millisecond clock should start from zero or not. Clearly deriving it from the 64-bit microsecond clock is a win. It won't wrap (not for 50,000 years at least). But the current clock starts at 0 when the image starts up. If one were to continue to zero the millisecond clock on image startup won't overflow into large integers for 12.4 days, but it isn't really a clock. Personally my preference is to indeed implement millisecondClockValue as microsecondClockValue // 1000, and simply live with the fact that its always a large integer.

millisecondClockValue
by Alain Plantec July 18, 2015

July 18, 2015

Hello, Is there any reason why we do not use microsecondClockValue to compute millisecondClockValue ? Other that "because someone has to do it" I mean. Iâve changed Time>>millisecondClockValue to be computed from microsecondClockValue and modulo change of the event stamp initialization, it seems to work normally. Cheers Alain

A solid border is supposed to be visible by default. If you don't want a border, don't add one? The default border style is BlNullRectanglerBorder Stephan
