[OpenSmalltalk/opensmalltalk-vm] fix libgit2 makefile (#390)
by maenu 10 Sep '20

10 Sep '20

I am using MacPort's CMake which works fine, except that it needs a path argument for the libgit2 makefile. Can somebody check if this is compatible with their CMakes?

[OpenSmalltalk/opensmalltalk-vm] primitives 54 and 554 for timesTwoPower: answer incorrect result on 64bits macOS VM (#383)
by Nicolas Cellier 20 Jul '20

20 Jul '20

This is due to a macOS bug in 64bits libm! (Hard to believe, isn't it?)

Support an updated image format number for Sista
by David T. Lewis 20 Jul '20

20 Jul '20

Hi Eliot, This is a belated follow up on earlier private discussion during a Squeak board meeting a few months ago, in which we agreed that identifying "Sista in use" in the image format number would be a useful thing to do. I previously added the documentation for this in ImageFormat-dtl.39.mcz (as well as the updated ckformat.c program to match). Attached here is a change set that can be loaded into a VMMaker image to add VM support for setting and reading the updated image format numbers. Here I used a primitive to initially set or clear the "sista bit". There are other ways this could be done, but this at least gets us started with a working implementation. By way of explanation, I am copying below both the change set preamble and the earlier ImageFormat commit notice: === Change Set: VMM-Sista-bit-dtl Date: 12 January 2020 Author: David T. Lewis Let the image inform the interpreter that alternate bytecodes either are or are not in use, and remember that setting when writing or reading the image format number in a shapshot file header. Provide primitiveMultipleBytecodesActive to allow the setting to be updated from the image. Expected usage is that the image can call this primitive after recompiling with Systa bytecodes, or after reverting back. Note that an alternative implemenation would be to use a VM parameter. The primitive was chosen here because it can perform parameter checking and does not require coordinated update the the VM parameter usage. Expected usage is that this feature will remain unused for some grace period (perhaps a few months) during which an updated VM can be widely circulated. After that period, images using Sista bytecodes may be safely saved with the updated image format number indicating that multiple bytecodes are in use. This change set includes helper methods in SmalltalkImage for testing or setting the multipleBytecodeSetsActive setting in the VM. Note the change set postscript which is necessary for initializing a class variable prior to code generation. === Name: ImageFormat-dtl.37 Author: dtl Time: 20 July 2019, 5:23:59.004 pm UUID: 52b464d5-0bf7-4326-bde3-4f18ad70b239 Ancestors: ImageFormat-dtl.36 Identify extended bytecodes for Sista in the image format number. Bit 10 identifies an image that contains extended bytecodes. Thus a 32 bit Spur image is 6521, with Sista it is 7033, and a 64 bit Spur image is 68021, with Sista it is 68533. It is expected that additional bytecode sets can be identified by an additional field in the image header, probably 32 bits containing two 16 bit fields, if both zero then Sista. Per discussion with Eliot and Bert in a Squeak oversight board meeting 2019-05-15. Dave

64 bit FFI (was: porting Croquet to Squeak6.0 alpha...)
by Bert Freudenberg 09 Jun '20

09 Jun '20

I'd suggest to get OpenGL working outside of Croquet first: http://www.squeaksource.com/CroquetGL.html Step 1: Verify this works in 32 bits. (assuming you are doing this on Linux, you can run 32 bit Squeak side-by-side with the 64 bit one) Step 2: Make it work in 64 bits. The second step requires that you understand how FFI works, and how it handles e.g. pointers and integer sizes. I am assuming we do have a working 64 bit FFI, at least for x86_64 machines. E.g. the OGLUnix>>glExtGetProcAddress: method returns a pointer. On a 32 bit system, that fits into a 'ulong' which is 32 bits. On a 64 bit system, a pointer is 64 bits wide so it would not fit into a 32 bit word. Now I don't know how many bits 'ulong' has in our 64 bit FFI, but that declaration may have to change. Etc. pp. If you have questions about FFI then those are best directed at the vm-dev list since it is dealing with VM-level interfaces. CC'ing, please follow up there. - Bert - On Wed, Mar 11, 2020 at 2:54 PM gettimothy via Squeak-dev < squeak-dev(a)lists.squeakfoundation.org> wrote: > Okey dokey, > > Poking along, there is a stray glyph in OGLUnix openGLLibraryName after > > openGLLibraryName > ^Smalltalk osVersion = 'linux' > ifTrue: ['libGL.so.1'] > ifFalse: ['GL'] > > I removed it in my install and got past that error. > > Working exclusively with Croquet(Master)... > > > > My next error is in OGLUnixX11LE(OpenGL)>>glMatrixMode: > > glMatrixMode: mode > "This method was automatically generated." > "void glMatrixMode(GLenum mode);" > <apicall: void 'glMatrixMode' (ulong) module: '#openGLLibraryName'> > ^self externalCallFailed > > The <apicall:...> fails > > How to think about this? > > Is Croquet behind OpenGL latest? > Would teaching myself OpenGL programming be of use to the Croquet project? > > cheers, > > tty > > >

[OpenSmalltalk/opensmalltalk-vm] GC crash on (corrupted?) image resume (#391)
by Holger Freyther 25 Apr '20

25 Apr '20

This happens with 1d9c8bcfd3214c52e8a449840b2cd1c448b33d18 on MacOS 64bit. The Assert VM doesn't see to trigger on any asserts. The GC seems to follow an object ending in a NULL OOP? The image includes non opensource code but it is crashing reliable on start-up.

[OpenSmalltalk/opensmalltalk-vm] SSL plugin might fail on Windows 7 (#236)
by CyrilFerlicot 25 Apr '20

25 Apr '20

If I execute this code: ```Smalltalk ZnClient new url: 'https://google.com'; get. ``` I get a result. If I execute this code: ```Smalltalk ZnClient new url: 'https://github.com'; get. ``` I get this error: Error: SSL Exception: connect failed [code:-5] I tried with both stable and latest vm. (The stable is from august 2017 I think) I sent a mail on the Pharo dev ML and we are at least two having this problem with Windows 7 when it's working with Windows 10.

*I have copied the below issue from https://github.com/hpi-swa/smalltalkCI/issues/366.* Hi! Time to time, the Pharo VM crashes, without any apparent reasons. For example, in https://travis-ci.org/ObjectProfile/Roassal2/jobs/365943067 ``` VM: 201708271955 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Date: Sun Aug 27 21:55:26 2017 +0200 $ Plugins: 201708271955 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ C stack backtrace & registers: eax 0x1e750080 ebx 0x00000100 ecx 0x00000020 edx 0x00000002 edi 0x00000020 esi 0x00000020 ebp 0xbff09c58 esp 0xbff09c58 eip 0x000e848d 0 Pharo 0x000e848d fetchByteofObject + 9 1 Pharo 0x00149400 reportStackState + 819 2 Pharo 0x001497a2 sigsegv + 191 3 libsystem_platform.dylib 0xa1742e5b _sigtramp + 43 ``` And a bit below: ``` Smalltalk Smalltalk stack dump: 0xbff11ce8 I SessionManager>snapshot:andQuit: 0x6b496a8: a(n) SessionManager 0xbff11d18 I [] in SmalltalkImage>snapshot:andQuit: 0x5517fa0: a(n) SmalltalkImage 0xbff11d3c I CurrentExecutionEnvironment class>activate:for: 0x5af3520: a(n) CurrentExecutionEnvironment class 0xbff11d64 I DefaultExecutionEnvironment(ExecutionEnvironment)>beActiveDuring: 0x5e2bc70: a(n) DefaultExecutionEnvironment 0xbff11d88 I DefaultExecutionEnvironment class>beActiveDuring: 0x5b1d8a8: a(n) DefaultExecutionEnvironment class 0xbff11dac I SmalltalkImage>snapshot:andQuit: 0x5517fa0: a(n) SmalltalkImage ``` It seems to happens randomly /cc @bergel -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] pixman 0.34.0 tests fail entire build on High Sierra (#258)
by Jim Haungs 25 Apr '20

25 Apr '20

A plain ./mvm build on MacOS 10.13.4 (in any of the build.macos64x64/pharo.* directories) fails with this error: > utils-prng.c:207:27: error: use of unknown builtin '__builtin_shuffle' [-Wimplicit-function-declaration] > randdata.vb = __builtin_shuffle (randdata.vb, bswap_shufflemask); > ^ > utils-prng.c:207:25: error: assigning to 'uint8x16' (vector of 16 'uint8_t' values) from incompatible type 'int' > randdata.vb = __builtin_shuffle (randdata.vb, bswap_shufflemask); > ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > It's trying to build the tests for pixman. There is a patch for this bug here: https://bugs.freedesktop.org/show_bug.cgi?id=104886 But when I apply the patch, the patched utils-prng.c file gets overwritten with the old version by something in the build or configure step, so the patch disappears and the build error returns. -- You are receiving this because you are subscribed to this thread.
