I have attached a copy of his change set, and here is the message that he originally posted: ----- This prevents the potentially serious consequences of killing off the WeakArray finalization process. Please review this soon! from preamble: "Change Set: EnsureEssentialProcesses-nk Date: 21 June 2004 Author: Ned Konz It's possible to kill off the WeakArray finalization process, and it never gets restarted. This can cause many hard-to-diagnose problems. This change set ensures that the WeakArray finalization process is started at every start up. It also shuts down the EventSensor's interruptWatcherProcess and eventTicklerProcess at shutdown time (and starts them at startUp time, of course). "!

[BUG] Changing name project in SqueakSource and using Monticello
by Samir Saidani 30 Jun '04

30 Jun '04

Hi, I have a project named Graph and can access it without problem through Monticello. I have renamed this project to Graphs and now I can't access to this project at all. But the old name seems to be still in use : I can open this project in Monticello even if it no longer exists. I wait one day (I thought that it could be a SqueakSource refresh problem) but the problem is still here. Thanks for this great tools I use now extensively ! Samir

Hi! I'm just wondering if anybody ever tried to write a Double class to support 64 bit floating point calculations in squeak. Martin

The Magic Book - a design draft
by goran.hultgren＠bluefish.se 30 Jun '04

30 Jun '04

The idea of a "Magic Book" inside Squeak acting as both an introductory documentation for Squeak and as a reference manual is quite intriguing. A few basic ideas that got this started: - Tying unit tests to documentation in order to detect stale documentation - Not bloating the image - Easily maintain the book cooperatively (like swiki) Ok, what would be the STTCPW? (For all you non XP aware: "Simplest Thing That Could Possibly Work"). By applying reuse - what do we already have? We already have: - Projects: A very good format for "active content". I am not sure how easily they are backwardscompatible though. Could anyone post some insight in that matter? - StarBrowser: A universal UI kindof thing. We could easily let StarBrowser be the main UI of the Magic Book! It lends itself easily for the task - a treeview on the left, a dynamic area to the left etc. If we somehow find a good way to integrate a little search form then it would be quite perfect. - SqueakMap: In whichever form we choose to have the Chapters of the book (Projects) we could register them on SM (a few new categories would be nice) and thus get a distributed always up to date model of chapters for free. And when SM1.1 gets completed it will track versions of the chapters for us, etc. And in SM1.1 it will have a sensible smart diskcache for the packages (read Chapters) so we get that too. - Free text engine: Scott Crosby wrote a neat little engine for maintaining keyword indices that the book obviously should use. I have also been intending to integrate that into SM. We should be able to add it to SM in such a way that the Magic Book can simple get that "for free". So... we already have a bunch of cool technology to implement the Magic Book IMHO. We just need to knit it all together in a smart way. If we split the book in the following pieces: 1. The TOC. This is essentially a list of chapters organized in a hierarchy with names and a link to the corresponding SM package that is the chapter content - a Project. 2. The chapters themselves. These are simply Projects published as packages on SM. Perhaps we need to follow a few conventions for these Projects so that we easily can "jump into" them in a proper manner, extract keywords for indices etc. 3. The search indices and the index (as books have last). If 1 and 2 above also are packages on SM (in whichever suitable form, doesn't matter) it will be even more simplified. So the book *contents* are then managed as packages on SM. We get the possibility of having different owners for different chapters, release/version tracking etc. It is obvious when you think about it - why shouldn't they be packages? The StarBrowser is the obvious choice of a UI - it already has navigation mechanisms and it can also show contents from the book along with other things in a highly dynamic fashion. Why reinvent that? And SqueakMap gives us a lot of stuff like efficiently always updated content, a smart cache etc. And there will be no image bloat whatsoever. Well, ok, what do you all think? Darn, this sounds like real fun... I need to get cranking at my SM1.1 ... :-) regards, Göran

ImageSegment loading fails (again)
by goran.krampe＠bluefish.se 30 Jun '04

30 Jun '04

Hiya! Now this issue popped up again. And I have no idea how or why. Anyway, the primitive called from #loadSegmentFrom:outPointers: fails and returns nil. Not sure how to figure this one out. Right now I am playing around with optimizations but switching everything off didn't help either, I am not sure it is an optimization thing - at least not in the VM. bash-2.05b$ uname -a Linux zaphod 2.6.7-beta #2 Wed Jun 30 10:42:53 CEST 2004 i686 unknown unknown GNU/Linux bash-2.05b$ squeak -version 3.6-3 #1 Wed Jun 30 12:43:58 CEST 2004 gcc 3.3.3 Squeak3.6 of '6 October 2003' [latest update: #5429] Linux zaphod 2.6.7-beta #2 Wed Jun 30 10:42:53 CEST 2004 i686 GNU/Linux default plugin location: /usr/lib/squeak/3.6-3/*.so regards, Göran PS. Not filing a bug report just yet, because I am not sure that I haven't goofed this somehow...

Optimizing Squeak on Lunar Linux...
by goran.krampe＠bluefish.se 30 Jun '04

30 Jun '04

Hi people! Just wanted to share some numbers - kinda interesting. I am running Lunar Linux, kernel 2.6.7 all built locally. The CPU is a Pentium-M (mobile) 1.5Ghz which is a spiced up PIII that actually matches a P4 with double the speed (!). I use GCC 3.3.3 which doesn't yet support Pentium-M explicitly but after searching around I found out that I should use PIII arch and NOT use SSE2, since it is borken for Pentium-M in GCC older than 3.4, sigh... Ok, I have now made a Lunar module for Squeak, so rebuilding/reinstalling Squeak is just a simple "lin -c Squeak". Very nice. So I wanted to see how performance differs when I play with optimization, first I built myself a sturdy baseline really boring and slow VM (-O0, no optimizations at all): '127617148 bytecodes/sec; 2644928 sends/sec' Then I went bananas and flipped every switch ON, banzai! Well, had to flip a few back off because it didn't want to compile (and SSE2 actually seemed to slow things down) and I ended up at: '216765453 bytecodes/sec; 7000153 sends/sec' '219554030 bytecodes/sec; 6594158 sends/sec' '218243819 bytecodes/sec; 6694354 sends/sec' Woah! That is one BIG difference! I had no idea these things mattered *that* much! Of course I have no idea if the resulting VM is stable or not - but it seems to run fine. :) regards, a Lunar-convert, Göran DS. Darn it is fun playing with a source distro! Perhaps Gentoo is just as much fun, but Lunar really shines IMHO. And I do have a nice working Squeak module for it. :)

[UPDATES] 4 for Squeak3.7beta
by dway＠mailcan.com 30 Jun '04

30 Jun '04

A few more fixes that have straggled in before 3.7gamma. I didn't have time to put together a gamma image last week, but I have a bit of time this week so I should be able to do it in the next few days. - Doug ------------------------------ 5964FileList2preferrenceFix -- Karl Ramberg -- 20 June 2004 Seems like there was a bug in this update with a call to startsWith: which was not in my image. I changed that to beginsWith:. I also added a postscript to update the Tools flap" 5965WaveEditorInitFix-nk -- Ned Konz -- 22 June 2004 The default WaveEditorMorph in the Objects catalog wasn't getting its data initialized correctly. Because of this, it wouldn't store on disk properly. This change set changes the initialization of the default WaveEditorMorph to use a real sound instead. 5966SuppressCtrlKeyBrowser-nk -- Ned Konz -- 21 June 2004 v2: fixed what to show in MVC. Now that we have the 'what to show' menu, the use of the control key to display decompilation without temps and the use of the shift key to display decompilation can be replaced with a single modifier key in the 'show decompiled' code holder views. This avoids the surprising and mystifying behavior upon accidentally accepting a method with Ctrl-Alt-S, which can on some platforms display a decompiled method with no temp names. This change set: * removes sensitivity to Ctrl and Shift keys in all but the 'show decompiled' mode of the various browsers * factors all of the decompilation display logic into a single method * retains backwards compatibility with other browsers * makes the 'what to show' menu also work in MVC (so as not to lose the ability to display decompiled methods in the MVC environment) * makes the display of decompiled code *without* temp names be the only special key sequence: if you're already displaying decompiled methods and hold the shift down when you select a method, you will see the decompilation without the temp names. 5967nilUUIDFix-pk -- Pavel K?ivánek -- 28 June 2004 Reposted by: Ned Konz CS 5919KCPInitializeNewFix broke UUID>>nilUUID because UUID defined an initialize method and did not expect to have it called from its new: method. This change set fixes that problem. Pavel's comments: UUID nilUUID -> de6309fd-188f-0643-9c90-0edb825f2f46 UUID nilUUID isNilUUID -> false Fixed: UUID nilUUID -> 00000000-0000-0000-0000-000000000000 UUID nilUUID isNilUUID -> true Ned's comments: I have scanned the image and verified that UUID is the only variable class that defines an initialize method. variableClasses := Behavior allSubInstances select: [ :ea | ea isVariable ]. variableClasses select: [ :ea | ea includesSelector: #initialize ]. <This automated message brought to you by the UpdateIncorporationTool.> <See the UpdateIncorporationTool package on SqueakMap for details.>
