4.2 update configuration (was: trunk development)
by Chris Muller 03 Feb '11

03 Feb '11

Ok, I've studied our update code, but have a couple of questions. First, what is the "Squeak-Version" package about? Is it merely to declare which update number we're at? I didn't see where this has any bearing on the actual update processing. I've copied the update-ar.1.mcm configuration to the new 4.2 repository, but I don't see whether any further change is needed. The "1" version number of the mcm configuration file is only used to filter out all of the "update-xxx.mcm" files with a lower version number (minVersion), but since we only have one configuration that is not used. Then there is MCMcmUpdater's "LastUpdateMap" class variable. This gives us the minVersion update number for a particular repository but, in my image, both #'s (for 'trunk' and for '4.1') are very low. Thanks..

linux build stability
by Eliot Miranda 02 Feb '11

02 Feb '11

Hi All, you may already know that there have been strange stability problems with the Cog VM on linux. Problems with the heartbeat appear to derive from specific compilations, one compilation of the same source producing an executable that will crash, another producing one that won't. recent testing at Teleplace showed that an effect due to what was presumed to be a compiler bug (specifically the optimization level used to compile the heartbeat, high causing a crash) was not repeatable. So today in building new production VMs for Teleplace I decided to do three parallel linux builds and see if all produced the same results. While there are macros used in the source that are date dependent (use of __DATE__) AFAIA there are none apart from version.c/version.o that depend on time, and no timestamps or current directory paths in linux objects, and so, provided different compilations of the same source are done on the same day, the results should be bit-identical. In my experiment this turns out not to be the case, which is more than a little alarming. What I'm seeing is different results duplicating unixbuild/bld to unixbuild/bldb and unixbuild/bldc, doing identical configures and makes in each of the three directories and then comparing resulting objects. I see this in a bare metal laptop with local sources running CERN SLC5 and on a Parallels VM running CentOS 5.3 (both derived from RHEL). I'm using gcc 4.1.2. Here's a script that shows example differences: bld$ for f in *.o vm/*.o; do echo $f;cmp $f ../bldb/$f; cmp $f ../bldc/$f; done disabledPlugins.o disabledPlugins.o ../bldb/disabledPlugins.o differ: byte 200, line 4 disabledPlugins.o ../bldc/disabledPlugins.o differ: byte 200, line 4 version.o version.o ../bldb/version.o differ: byte 166, line 3 version.o ../bldc/version.o differ: byte 166, line 3 vm/aio.o vm/cogit.o vm/debug.o vm/gcc3x-cointerp.o vm/osExports.o vm/sqExternalSemaphores.o vm/sqHeapMap.o vm/sqLinuxHeartbeat.o vm/sqLinuxWatchdog.o vm/sqLinuxWatchdog.o ../bldb/vm/sqLinuxWatchdog.o differ: byte 33, line 1 vm/sqLinuxWatchdog.o ../bldc/vm/sqLinuxWatchdog.o differ: byte 33, line 1 vm/sqNamedPrims.o vm/sqNamedPrims.o ../bldb/vm/sqNamedPrims.o differ: byte 6346, line 30 vm/sqNamedPrims.o ../bldc/vm/sqNamedPrims.o differ: byte 6346, line 30 vm/sqTicker.o vm/sqUnixCharConv.o vm/sqUnixExternalPrims.o vm/sqUnixMain.o vm/sqUnixMain.o ../bldb/vm/sqUnixMain.o differ: byte 31415, line 170 vm/sqUnixMain.o ../bldc/vm/sqUnixMain.o differ: byte 31414, line 170 vm/sqUnixMemory.o vm/sqUnixThreads.o vm/sqUnixVMProfile.o vm/sqVirtualMachine.o Using objdump --disassemble I can see for example that sqLinuxWatchdog.o and sqUnixMain.o differ only in the symbol table, not the executable code. So perhaps this is not meaningful, and merely noise. But with simple files like disabledPlugins.c that different objects are produced at all in different runs is rather worrying: bld$ cat disabledPlugins.c /* this should be in a header file, but it isn't. ho hum. */ typedef struct { char *pluginName; char *primitiveName; void *primitiveAddress; } sqExport; sqExport vm_display_Quartz_exports[] = { 0, 0, 0 }; sqExport vm_display_custom_exports[] = { 0, 0, 0 }; sqExport vm_display_fbdev_exports[] = { 0, 0, 0 }; sqExport vm_sound_MacOSX_exports[] = { 0, 0, 0 }; sqExport vm_sound_NAS_exports[] = { 0, 0, 0 }; sqExport vm_sound_OSS_exports[] = { 0, 0, 0 }; sqExport vm_sound_Sun_exports[] = { 0, 0, 0 }; sqExport vm_sound_custom_exports[] = { 0, 0, 0 }; I wonder - do you see the same effect? - does this happen with gcc versions other than 4.1.2? - does it happen on non-RHEL-derived distros? - is this a meaningful signal or just harmless noise? - what am I doing wrong? Clearly I need to look more carefully but I thought I'd ask y'all in order to understand and hopefully solve the build instabilities as swiftly as possible. If you do want to try and reproduce this simply duplicate the build directory (unixbuild/bld in the Cog VM source) twice and do three separate configures and makes, one in each of the build directories, each from the same source code. Then run some variation fo the script above to compare the object files so produced. best Eliot

If the decoding is right then the issue is with fonts. See isFontAvailable and installFont methods in LanguageEnvironment to see how to load language-specific fonts on startup.

Unfortunately not, because of the need for backward compability across multiple OSes and platforms. To select the right converter, use class side methods in SimplifiedChineseEnvironment. See JapaneseEnvironment for help. > I am just a beginner on Squeak Smalltalk, please correct me if I make any > mistakes on understanding Generally, requests to this mailing list receive brief responses. If you need more detail, you could try the beginners mailing list. Squeak needs people like to you to increase support for Chinese locales. Subbu

trunk development
by Chris Muller 01 Feb '11

01 Feb '11

We have a reasonable candidate image and a 4.2 release repository to which fixes could be backported even if it that became necessary. 4.2 is not yet released, but the release activities can occur simultaneously with new development, so I see no reason for us hold up new trunk contributions any longer. Please feel free to resume new development in trunk.

[meetup] Buenos Aires, wednesday 7pm
by merlyn＠stonehenge.com 01 Feb '11

I know there are probably more than a few squeakers in Buenos Aires. I'm in town for a cruise, and have settled on Wednesday, 7pm for a meetup. We'll start at the Emperador Hotel (since that's where I'm staying) but likely move to one of the bars nearby if the prices are better. :) -- Randal L.
