ffi-test-main.c fails on FreeBSD
by Gary Dunn 12 Aug '16

12 Aug '16

In conjunction with getting Open Cobalt running on FreeBSD I have been looking into the problems with SqueakFFIPrims on FreeBSD and have reached a point that is beyond my understanding. I am not sure if the fix should come from the VM side or the FreeBSD port maintainer. I needed to get source code back into the ports tree so I did a make in /usr/ports/lang/squeak. I already had the 3.9 tarball, so that just repopulated the source and did the initial build. In the "files" folder I found patch files typical for a FreeBSD port. These patch source files from a generic tarball to work with FreeBSD. The one of interest was patch-platforms__unix__plugins__SqueakFFIPrims__ffi-config which contains ----x-----x----- --- platforms/unix/plugins/SqueakFFIPrims/ffi-config.org Wed Apr 26 20:27:53 2006 +++ platforms/unix/plugins/SqueakFFIPrims/ffi-config Wed Apr 26 20:29:00 2006 @@ -39,6 +39,7 @@ case ${abi} in linux) abi=sysv;; + freebsd*) abi=sysv;; darwin*) abi=darwin;; *) abi=libffi; lib="-lffi";; esac -----x-----x----- I then had the folder work/Squeak-3.9-7/platforms/unix/plugins/SqueakFFIPrims In it is a file 00README which explains how to test FFI. It says to run ffi-test-config but I have no such file. It says to type "make" to build a test suite but the build failed. It says to try with make CPU=any ABI=libffi LIB=-lffi which also failed. I traced the problem to the gcc search paths for includes and libraries -- turns out FreeBSD only searches /usr/include and /usr/lib when the required files are in /usr/local/include and /usr/local/lib. After some fiddling I finally had a "main" to test. It failed: ffi-test-main.c failed at line 361. Here is a bit from that file, ending with line 361: ffiInitialize(); for (ul= 0; ul < 15; ++ul) ffiPushSingleFloat(fa[ul]); GO(FFITypeSingleFloat, many); f= ffiReturnFloatValue(); ffiCleanup(); CHECK(f - ff < FLT_EPSILON); I worked out the CHECK macro but could not find what FLT_EPSILON is. At that point I decided to stop and come to you for help. Where do I go from here? -- Gary Dunn, Honolulu osp(a)aloha.com http://openslate.net/ http://e9erust.blogspot.com/ Sent from Slate001

Maintainer of FFI-Package
by Nicolai Hess 12 Sep '15

12 Sep '15

Who is the maintainer of the FFI-Package for Squeak and/or Pharo ? I especially interested in the FFI-Unix examples and the state on working FFI on linux for current squeak release (AFAIK it does not work with "squeak all in one" 4.5) regards Nicolai

Long path name support added for win32
by Marcel Taeumel 15 May '15

15 May '15

sqWin32FilePrims.c <http://forum.world.st/file/n4796045/sqWin32FilePrims.c> Hi! :) I added support for long path names according to the hint given here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%… Just prepending "\\?\" in that case. Further limitations may have to be investigated. ;) Eliot, could you add this to the VM trunk?

Cog 15.00.3205 / SqueakSSL
by Tobias Pape 10 Apr '15

10 Apr '15

Hi all Eliot's latest CogVM 15.00.3205 provides a SqueakSSL that seems to be linked against libcrypto.so.10 libssl.so.10 however, I am unable to find either for current or just outdated Debian/Ubuntu. Probably I didn't look hard enough. Anybody knows where to get them?

New Cog VMs available
by Eliot Miranda 04 Feb '15

04 Feb '15

at http://www.mirandabanda.org/files/Cog/VM/VM.r3236/ CogVM binaries as per VMMaker.oscog-eem.1029/r3236 Fix stupid, stupid bug in copying vm profile samples between buffers when the circular buffer index has wrapped. Fix monumental blunder in jitted store-check code. The saved registers mask needs to be the *or* of the value reg and the caller-saved registers, not the *and*!! Make the pin primitives Spur-only. Never inline mapStackPages, for debugging. Spur: Reduce the max num literals in the alternate header format to 15, and steal the bit for the Sista optimized method flag. Make postBecomeAction's stack sweep only occur in Spur (fix regression). Refactor so that the scan is not inlined. Don't assume newMethod is non-immediate in post-become actions. Fix stack adjust slip in primitiveSmallFloatTimesTwoPower Make ensureBehaviorHash: fail for uninitialized behaviours and hence fix the Behavior basicNew basicNew hang. Optionalize some api methods the Spur Cogit doesn't use. Rename and correct ensureSemaphoreForwardedThroughContext: to ensureSemaphoreUnforwardedThroughContext:, its intended function. Make shouldRemapObj: filter-out objects already in newSpace since mapStackPages, via mapInterpreterOops, can visit objects twice in a scavenge, GC, compact sequence. Make sure the caller (& saved) context(s) in base frames stack page are followed post-become in followForwardingPointersInStackZone:. Fix bad bug introduced in become changes in VMMaker.oscog-eem.841 through 844. The class table contains puns, e.g. using Array and WeakArray. These class index puns must not mislead the allInstances primitive into concluding that the class in question is at multiple indices and wrongly purge it. Fix slip in primitivePin. Also be lenient w.r.t. unpinning married contexts. Move the check down into StackInterpreter's version. This allows e.g. self allObjectsDo: [:o| o unpin] Bow to the inevitable and add a manual override for primitive accessor depth. Use it in at: & at:put:. If manual override is not used then the automatically computed depth is too deep because of context access. Newspeak: Integrate Ryan's newer absent receiver sends, which first apeared in VMMaker.oscog-eem.919, abandoned because of Glue issues now resolved. Includes nice refactoring of absent send argument marshalling into its own routine. LargeIntegersPlugin: Remove/fix assumption of 32-bit digit length in normalization routines. -- best, Eliot

SqueakJS JSBridge
by Jerry Bell 31 Jan '15

31 Jan '15

Hello, I'm trying to run the JSBridge callback example from a 4.5 image. JSBridge.st is loaded and I'm running under Chrome on Windows. I get an error: "Error:primReturnFromCallback: failed. " Digging a little in the debugger, I find in JSObjectProxy>>handleCallback, result is : "Error: Error: This block accepts 2 arguments, but was called with 0 arguments". Modifying the example with a callback block with 0 arguments works. The JSBridge demo on the SqueakJS site seems to be working fine. Any ideas? Thanks! Jerry

[commit][3244] CogVM source as per VMMaker.oscog-eem.1034
by commits＠squeakvm.org 31 Jan '15

31 Jan '15

Revision: 3244 Author: eliot Date: 2015-01-30 18:15:58 -0800 (Fri, 30 Jan 2015) Log Message: ----------- CogVM source as per VMMaker.oscog-eem.1034 Spur: Clarify and ensure that we always follow receivers after any become to ensure that e.g. super sends on non-pointer receivers (which don't check) will have unforwarded receivers and hence any primitives that don't validate their receivers will function correctly.

Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-eem.1034.mcz ==================== Summary ==================== Name: VMMaker.oscog-eem.1034 Author: eem Time: 30 January 2015, 6:12:49.023 pm UUID: 1a93b31c-cf2c-4a2c-b53f-9eae1d7863c7 Ancestors: VMMaker.oscog-eem.1032 Clarify and ensure that we always follow receivers after any become to ensure that e.g. super sends on non-pointer receivers (which don't check) will have unforwarded receivers and hence any primitives that don't validate their receivers will function correctly. Better safe than sorry. Don't prune unreachable code in plugins since the pruning code doesn't yet work correctly for them.
