Re: [Vm-dev] [OpenSmalltalk/opensmalltalk-vm] Changes to sq.h and sqAssert.h to accompany commit (aafcb78)
by Nicolas Cellier 23 Apr '21

23 Apr '21

I've tried adding EXPORT/IMPORT declarations in sqVirtualMachine.h, but it's not such a good idea - many function prototypes are duplicated in various win32/vm/*.c without the EXPORT, so it breaks in many places - most external plugins won't need the IMPORT, because they call functions through the VirtualMachine structure rather than attempt to directly link them. I've sketched a lightweight solution in branch https://github.com/OpenSmalltalk/opensmalltalk-vm/tree/fix_include_order. The branch can build the VM for the 3 major OSes (linux, macos, windows). It remains to know if the solution is compatible with TERF. Before I emit a pull request, Eliot, your comments are welcome. -- You are receiving this because you are subscribed to this thread.

Fixing linux builds
by Nicolas Cellier 23 Apr '21

23 Apr '21

Hi all, the branch https://github.com/OpenSmalltalk/opensmalltalk-vm/tree/fix_include_order tries to fix the linux builds. Eliot, could you review if compatible with TERF VM build? I succeeded in building the linux and macos VM. Travis status is still red, because there are random failures on macos 32bits spur during tests. Either the tests result in SEGV or they stale... Of course, when running all 5.1 tests with self compiled 32 bits VM, I could not reproduce...

patch for subversion (classical VM) primitiveLocalMicroseconds
by stes＠PANDORA.BE 22 Apr '21

22 Apr '21

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, This is a patch for subversion squeakvm 4.19.6. It relates to the primitiveLocalMicrosecondClock. It does not affect OpenSmalltalk (I think the code in OpenSmalltalk is different and is not affected by the following problem). I'm not sure it is actually desired at all to implement primitiveLocalMicrosecondClock in the 32bit case in the classical SqueakVM, but if it is, there is an arithmetical overflow on my platform (Solaris 32bit). I don't think it affects the classical SqueakVM Solaris 64bit by the way, (for the 68000 type of Smalltalk images). The patch is for the file platforms/unix/vm/sqUnixMain.c function sqUnixUtcWithOffset(). This function is doing: time_t seconds= timeval.tv_sec; suseconds_t usec= timeval.tv_usec; *microSeconds= seconds * 1000000 + usec; unfortunately the multiplication (seconds * 1000000) is triggering overflow. The type time_t is defined for me as: typedef long time_t; typedef long suseconds_t; /* signed # of microseconds */ Note that I believe that in the 32bit case this has size 4 bytes and in the 64bit case this has size 8 bytes (for me on Solaris). So Solaris 64bit is not affected by the multiplication error, but 32bit is. I propose the following patch: Index: vm/sqUnixMain.c =================================================================== - --- vm/sqUnixMain.c (revision 3799) +++ vm/sqUnixMain.c (working copy) @@ -213,11 +213,13 @@ */ sqInt sqUnixUtcWithOffset(sqLong *microSeconds, int *offset) { + sqLong theMicroSeconds; struct timeval timeval; if (gettimeofday(&timeval, NULL) == -1) return -1; time_t seconds= timeval.tv_sec; suseconds_t usec= timeval.tv_usec; - - *microSeconds= seconds * 1000000 + usec; + theMicroSeconds = seconds; + *microSeconds= theMicroSeconds * 1000000 + usec; The rationale is that the function seems to assume anyway that it is possible to store the result in *microSeconds which is of type sqLong. So by defining a local variable theMicroSeconds and casting seconds to that type, and then multiplying (instead of 32bit multiply, on the 64bit), it may work ... at least it seems to work for me. Maybe an alternative could be simply NOT to implement primitiveLocalMicrosecondClock in the 32bit case ... If primitiveLocalMicrosecondClock would return nil (primitiveFail) in the 32bit case, it would also be a possible solution. The primitive assumes anyway that it returns the microseconds as LargeInteger. David Stes PS1: in attach the patch to apply if desired PS2: I've tested this on Solaris - all platforms are affected; it is hard to say for me how other platforms are affected, given their time_t definition and their sqLong definition. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJgfw4nAAoJENdFDkXGicizFVQH/3GhR/K0K9H9AyS4uBCeEIxg lv4rCq2w9tXWeLP8eUc50sJnAsK7UVnO6FUpdFmF0qauN0414C5KmrQcIivNoEvH kMiWduIWXfzX7VlHj56pyuYym73qOZDZowFOvnPjaVQfKcqC9yyabYrEF7THc8j3 F8bVwCy/oz1h9/Mi6VbCrjz1G+ePmowXiv5vkJFAwQDNGrc53OyhQm6Wfibdwb/8 6C2C/loPeStDf9f3Y3zhIkelp0RI4TL+h+D+REaf0kWV/TubIx648hcP4uvBhyQk 6hwD7OHHechkJLgYAni1ipGXfX03cAM2plLIgKHahypNz1mVcZhu/6SSMTQK1ik= =gf1g -----END PGP SIGNATURE-----

Re: [Vm-dev] [Cuis-dev] Cuis 68000 64bit V3 image ?
by ken.dickey＠whidbey.com 22 Apr '21

22 Apr '21

David, Sorry for the delay. Busy life. I was hoping someone else would repond to this. There are only the 3 supported Cuis image structure variants. With a virtual machine, 68K is not an "image kind exists" problem as much as a "VM support kind" of problem. I suggest you ask the OpenSmalltalk folks on the vm-dev list (CC'ed) about a 68K VM which supports one or more of the currently available image formats. BTW, what OS are you running on? [E.g. "uname -a" on Linux/Unix] Good luck. -KenD ====== On 2021-04-20 10:38, stes--- via Cuis-dev wrote: > For the v3 image I have: > > $ /usr/lib/squeak/4.19.6-3799/ckformat src/cuis/Cuis5.0-4567-v3.image > 6505 > > 6505: a 32-bit V3 image with closure support and float words stored in > native platform order > > Question: does there exist a 64bit 68000 type of image for Cuis ? > > 68000: a 64-bit V3 image with no closure support and no native > platform float word order requirement > > The 2 other Cuis images I see are: Cuis5.0-4567.image and > Cuis5.0-4567-32.image > > 68021 > 6521 > > those are Spur images: > > 6521: a 32-bit Spur image with closure support and float words stored > in native platform order using Spur object format > 68021: a 64-bit Spur image with closure support and float words stored > in native platform order using Spur object format > > > My understanding is that there are very few Squeak images out there > that use the 68000 format. > I'm just curious whether there exists a Cuis image for that V3 68000 > format. > > Thanks, > David Stes
