Failing Tests in Pharo 4.0
by Sean P. DeNigris June 14, 2014

June 14, 2014

In a fresh 4.0 image, I get 10 failures and 11 errors. I guess this is why the monkey is failing validations... What do we do? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Failing-Tests-in-Pharo-4-0-tp4763069.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

new Cog VMs available
by Eliot Miranda June 14, 2014

June 14, 2014

...in http://www.mirandabanda.org/files/Cog/VM/VM.r3000/ CogVM binaries as per VMMaker.oscog-eem.772/r3000 Add libcrypto and libssl to Linux and Mac builds of the SqueakSSL plugin. Add the XDisplayControlPlugin and include it (external) and the AioPlugin (internal) to the linux x86 builds. Cog: Fix an abort (relocating call to invalid address) due to an over-zealous check in relocateCallBeforeReturnPC:by:. Since we relocate e.g. calls to primitives there can be no effective range check there-in. Spur: Fix fillObj: signedness for objects straddling the midpoint of the address space (quickly affects linux). Similarly for routines in pigCompact, to get asserts correct. Fix printOopsFrom:to:. for objects up to endOfMemory. Declare lastFreeChunk and firstFreeChunk correctly. Fix numberOfForwarders: and printForwarders: for isForwarded:'s blindness towards freeChunks. Comment isForwarded: to be clear on the issue. Have the segment manager pass to sqAllocateMemorySegmentOfSize: the address of the first large enough gap in the address space, instead of the address of the end of the first segment. This allows e.g. linux to use MAP_FIXED and hence get past a 128Mb limit on mmapping. Fix bugs in isValidFreeObject: & printFreeTreeChunk: that caused bogus assert failures. Remember to include the Spur moniker in the -version output on linux -- best, Eliot

Re: [Pharo-dev] [squeak-dev] New Cog & Spur VMs available

Hi StÃ©ph, On Fri, Jun 13, 2014 at 4:38 AM, StÃ©phane Rollandin <lecteur(a)zogotounga.net> wrote: > I got a crash right away with newest cogwin when opening my usual working > image. No simple case easy to reproduce yet. Dump is attached. > Thanks. This is fixed in VMMaker.oscog-eem.772. It was an overzealous bounds check on a relocated call of an interpreter primitive. The VM complained and aborted because the interpreter primitive;s address was out of the code zone (as of course it should be; it is in the interpreter) i.e. the VM should not have performed the check and should not have exited. Apologies. I'll be building and uploading new VMs soon. -- best, Eliot

Streaming uploads with Zinc (was: Kom or Swazoo?)
by Torsten Bergmann June 13, 2014

June 13, 2014

Hi Sven, following a discussion about Kom/Swazoo on the Seaside list: http://lists.squeakfoundation.org/pipermail/seaside/2014-June/030968.html there was a question if Zinc does support streaming uploads. Can you comment on that? Thanks T.

HowToMakeYourOwnTutorial, how to launch my own?
by Marc-Philippe Huget June 13, 2014

June 13, 2014

Hello everybody, I try to do a tutorial for our project and I decided to use ProfStef, so I follow the instructions as given in HowToMakeYourOwnTutorial, so * no problem to create a class inheriting from AbstractClass * creating two protocols lessons and tutorial * a method tutorial returning the list of tutorials as an array * a method per tutorial My only problem is regarding running this tutorial In ProfStef, we do ProfStef go but here, go is not recognized If I change from AbstractTutorial to PharoTutorial, I obviously have go, goOn and next but this is not my tutorial I guess this is a problem of player, but how? Thanks in advance for your help Regards, mph

New Cog & Spur VMs available
by Eliot Miranda June 12, 2014

June 12, 2014

see http://www.mirandabanda.org/files/Cog/VM/VM.r2987/ CogVM binaries as per VMMaker.oscog-eem.769/r2987 platform code: Type the memory allocators as accepting and answering usqInts to give a chance at allocating more than 2Gb. Use unsigned comparisons when testing if there's sufficient heap space in readImageFromFile:HeapSize:StartingAt:. Leads to accurate failure message when failing to allocate large heap. Correct syntax of inline assembler for byte and word swap operations in win32 16-bit displays. Thanks to Nicolai Hess! sqUnixX11.c: Include the right X11 include file to pull in the def for XK_equal (keysym.h vs keysymdef.h). Don't define BytesPerOop or BaseHeaderSize; these should be taken from interp.h. Integrate Philippe Back's fix for numberic keypads on X11; see https://pharo.fogbugz.com/f/cases/11352/. Add the XDisplayControlPlugin to the plugins loaded by the image build script. Use pthread_atfork to reinstall the heartbeat thread post fork. Make sure SIGALRM is unblocked if using the interval timer heartbeat on linux. Remove RPATH spec from unix builds. Include the executable name in the crash.dmp report. Fix stack backtrace printing on Mac & Unix to not segfault when invoked from error(char *msg) function. CoInterpreter: No longer inline CoInterpreter>>pre/postGCAction: for VM profiling. Fix instantiation of large non-byte objects. The old code for sufficientSpaceToInstantiate:indexableSize: stupidly subtracted BytesPerWord instead of ShiftForWord from LongSizeNumBits in determining the max size. Garbage collect/remap the primTraceLog correctly. If a GC happens very early in start-up the log circular buffer may not be full and the existing code assumed it always was. Add Spur-specific interpreter proxy functions for immediate character and pinning access. Implement the new Spur interpreterProxy API for ObjectMemory (of course pinObject: fails, and isCharacterValue: has a smaller range). Fix a bug in printing frame flags (order was the wrong way around). Allow vmParameterAt: 26 put: 0 to disable the heartbeat itimer. Add AioPlugin to Mac VMs. Make CoInterpreter>>printFrame: not mislead as to the number of temps in a block activation. Change the time primitives to access the time now, not the time as updated by the heartbeat (but /don't/ change the time basis for event checking. This for performance because use of gettimeofday in e.g. stack overflow can be a signficant performance overhead. Move the simulated time implementations (ioSeconds et al) up to StackInterpreter to reduce duplication. Add ioSecondsNow et al to the platform code to support this. Fix regression in primitiveUtcWithOffset, answer the correct local time offset. Fix ioSecondsNow to use the time now, not the heartbeat time. Revamp primitiveVMParameter to avoid overflow in values such as total heap size. Make statProcessSwitch, statIOProcessEvents, statForceInterruptCheck, statCheckForEvents, statStackOverflow & statStackPageDivorce 64-bit to avoid wrapping. Make sure that positive64BitIntegerFor: will not cause a GC just as positive32BitIntegerFor: doesn't. Make primitiveClone cope with variable args, cloning its last argument. This for the Newspeak VMMirror. Add primitiveAllObjects, adapted from VMMaker-dtl.339.mcz Add Nicolas Cellier's bitblt speedups, reference: Mantis issue 7802: Fast-up BitBlt rgbAdd rule Mantis issue 7803: Fast-up BitBlt alpha blending rules Check for valid bitmap in primitivePixelValueAt aka BitBltSimulation>> primitivePixelValueAtX:y: Fix provided by Nicolas Cellier. Reference Mantis 7799 Avoid including the instructionPointer in the context when marrying the top frame during divorceAllFrames for voidVMState..If:. (how did this ever work??) Fix a bug in BitBltPlugin>>lockSurfaces. Add the compression prims to the Newspeak VM's ZipPlugin. Fix roomToPushNArgs:; the Cog VMs can be more lenient because of the use of a stack instead of contexts. Fixes some valueWithArguments: failures. Integrate Nice's improved SmallInteger generated primitives that support int x float comparison, & hence speed-up int x float comparison enormously. Integrate VMMaker-dtl.328 (failure of primitiveDisplayString to advance destX). Integrate 2792, fix memory leaks in SqueakSSL on unix. Integrate VMMaker-tpr.325 7247: BitBlt Bug in alphaSourceBlendBits8. Integrate VMMaker-tpr.326, Fix a single-bit constant error in BitBltSimulation>>copyBits:Fallback: - change 16r3FFF to 16r7FFF to correct tallyIntoMap behaviour for Scratch using BenBlt on the Pi. Restrict at-cache to bytecodePrimAt[Put], eliminating it from primitive[String]At[Put]. Sionara the explicit noAtCache at:[put:] machinery in CoInterpreter now that the atCache is confined to the interpreter's special selector at:[put:] bytecodes. Speeds up Stack VM signfiicantly, e.g. a compile of Compiler package falls from 1.6s to 1.4s on 2.2GHz Intel Core i7 MacBook Pro. Restrict at-cache to bytecodePrimAt[Put], eliminating it from primitive[String] At[Put]. Undoes need for fix in VMMaker-oscog.44 of 7 January 2011: "Fix leaking of objects into the atCache due to ceSend:super:to:numArgs:'s use of executeNewMethod without always setting messageSelector." This renders messageSelector and lkupClass ephemeral, since they are live only during message lookup and because createActualMessageTo will not cause a GC these cannot change during message lookup. Hence eliminate them from markAndTraceInterpreterOops: & mapVMRegisters. Fix arg count for primPCREExecfromto Cogit: Streamline the genPrimReturnEnterCogCodeEnilopmart. Streamline genExternalizePointersForPrimitiveCall Have StackToRegisterMappingCogit>>genPushReceiverBytecode use ReceiverResultReg if it contains self. Fix a double free bug in unlinkSendsOf:isMNUSelector:. Harmless cuz the result is only a bogus count of how many methods freed. Beef up the cog method integrity check to verify a its methodObject is a CompiledMethod. Fix bug in unlinkSendsOf:isMNUSelector: (primitiveFlushCacheBySelector) where old code could free the method of an active frame. Fix an assert fail in mapFor:bcpc:performUntil:arg: (this for primitiveClass where the class table reference can be the first map entry). Fix a bug in Newspeak remapIfObjectRef:pc:hasYoung: with dynamic super sends which could compute an invalid target method. Rename pushExplicitOuterSendReceiverBytecode et al to pushExplicitOuterReceiverBytecode et al. These are not sends. Fix pc-mapping for NewspeakV4. Dynamic super sends should /not/ be annotated with IsNSSendCall, but wth the vanilla IsSendCall. This fixes a bug converting an interpreter activation of a method with a loop and a dynamic super send to a machine code frame. For performance, specify that mapFor:[bcpc:]performUntil:arg: are inlined, eliminating the perform/indirect function call. This adds of the order of 3% to the size of a cogit.o's text seg so is acceptable. Print (nil) next to the selector for cog methods with a nil selector. Fix bug in Cogit>>unlinkSendsOf:isMNUSelector:, used by primitiveFlushCacheBySelector. The method could leave sends linked to freed MNU PICs. -- best, Eliot
