[ENH] converse-raok
by ok＠cs.otago.ac.nz 03 Oct '02

03 Oct '02

from preamble: "Change Set: converse-raok Date: 2 October 2002 Author: Richard A. O'Keefe There are applications, like reserving a sorted collection, or sorting in reverse order, but not limited to those, where we would like to take the converse of a predicate. The converse of a function f : (x, y) -> z is a function converse(f) : (y, x) -> z. This change set adds a class BinaryBlockConverse and methods so that aBlock converse value: x value: y = aBlock value: y value: x. This version adds BinaryBlockConverse>>fixTemps."!

Bug in Morphic Project, Scripts, Windows 2000
by Alex Peake 03 Oct '02

03 Oct '02

Is this where one reports bugs? If not, perhaps someone could direct me. If so, here it is. Sqeak 3.2, last update #4956 Windows 2000 SP3 1.8GHz, 500MB ram * Open, Morphic Project (follow Roladex example) * Add Book to Project * Add Text to Project * Blue click, "eye" menu to get Scripts * Select "miscellaneous" * Select Book - do menu item * Add to Project ---------------- OK so far ? Yellow (quick) click on up/down arrows does nothing? (quick -> same as will bring up world menu etc.) * Yellow click, pausing down, causes next selection (correct) * Yellow click, holding down, cuases swift scrolling through (correct) * Yellow click on the up/down box edge displays menu (correct) ? Yellow click on a menu selects (apparently) unrelated choice? (delete -> change layout inset, search for text -> GIF file)? Alex

[BUG][FIX] Playfield background (was: [BUG] PasteUpMorph becomes a Sketch)
by Bert Freudenberg 03 Oct '02

03 Oct '02

Here are two fixes for Playfields in the omniuser environment. The first fixes a real bug, the second an inconsistency: Although Playfields behave like a Sketch in that they can be painted on, the graphic thus created could not be accessed like for a Sketch. Per Alan's suggestion I added a slot for the background, rather than changing existent behaviour. Andreas noted that the slot should be named "graphic" to be consistent with Sketches. "Change Set: PlayfieldBackground-bf Date: 1 October 2002 Author: Bert Freudenberg - When the backgroundMorph of a Playfield was dragged outside, odd things happened because the background inst var was not nilled out. Fixed. - Playfields now expose the graphic slot (located in cleaned up 'playfield' category)." With these changes, a script can be made that cycles a playfield through various variations in background graphic, which are created by just putting multiple modified copies of the playfield into a holder. Useful, e.g, for simple multi-level games. No release date announced yet ;-) -- Bert

[Bug] MPEG in OS X 10.2?
by Mark Guzdial 02 Oct '02

02 Oct '02

I can't get MPEG opening to work on my OS 10.2 Titanium Powerbook with a freshly downloaded new 3.2 image and VM (3.2.8Beta5). No error -- it just does nothing after selecting a file and clicking OK in the file dialog. The same download opens and plays MPEGs (exact same MPEG files) fine on my 10.1.5 G4 Desktop. I've tried rebooting with no luck. Is anyone else finding any issue with MPEGs in OS 10.2? (Of course, it could be something other 10.2, but that's the most glaring of the few differences between my TiBook and my G4 desktop.) I've also tried CocoaSqueak, but with the same result. Thanks!

I've submitted a new mac VM for distribution. It does contain one fix for os-x Jaguar (10.2) 3.2.8b8 a) exposed vmParameter 24 & 25 which control how memory is allocated/freed Smalltalk vmParameterAt: 24 put: 48*1024*1024. Smalltalk vmParameterAt: 25 put: 24*1024*1024. b) Added argv,argc, env variables to main (For UnixOSProcess plugin support) c) Fixed for Jaguar 10.2. Full screen mode cmd-tab broke menu bar hiding, this is a 10.2 bug d) Added support for IP_ADD/DROPMEMBERSHIP and the ability to bind to the wild card port (0). e) OpenGL changes for TEA 3.2.8b7 was testing release and not distributed to the public. 3.2.8b6 was testing release and not distributed to the public. I'd expect Bruce will let us know when and where to find it in 24 hours or so. -- ======================================================================== === John M.

RE: Reminder: Ottawa Carleton Smalltalk Users Group meeting Oct 3
by Valloud Andres 02 Oct '02

02 Oct '02

Hello. > Yes! I looked at it's web pages and it seems very interesting. I could not check it out as I run mac. Wasn't there a PC emulator complete with PC BIOS and everything for the Mac? If I remember correctly, it ran decently on a now old iMac. I don't quite remember the name of it... V something. Andres.

[Q] Will somebody pleas review my changesets?
by Torge Husfeldt 02 Oct '02

02 Oct '02

Hi group, I know, you are all probably very busy, but I don't think i'm expecting too much when i wish for one single member of this mailinglist to at least read my mail and comment on my changeset. In the past few weeks i have posted two cs that were explitly requested by list members and i didn't even get an ack. These were: [Enh]shrinkingSelection and WordprocessorStyleCursorMovement (in reply to: Text selection by: Tommy Thorn) http://swiki.gsug.org:8080/sqfixes/2657.html and: Re: is subclassing Project OK? (in reply to a message of the same Subject by Ned Konz) http://lists.squeakfoundation.org/pipermail/squeak-dev/2002-August/017398.h… respectively. There is a new message upcoming subjected: "[Enh]Auto Scroll" that i would like your opinions of, too. Please note that i am not expecting much. A simple note of the form - you are reinventing wheels here look for <searchString> in [Google|Swiki|mail-archive|other] - i tried it in <version-information> and it didn't work/filein due to [<short error description>|<walkback>] - inoticed your work and will probably try later (a bit unsatisfying but i would settle for it) would suffice. Please note also that i have invested some ours of work (ok, it was fun too) in these and am a bit disappointed to see them pass completely unnoticed. Hope to hear from you soon, Torge

Re: Update on MIDI lockup
by Bill Schwab 02 Oct '02

02 Oct '02

Curiosity got the better of me today, and I did some VM building. First, I made a simple manual switch of printAllStacks() for printCallStack() in the win32 pref menu, then built using the latest source tree from Source Forge. I put the new VM on the offending machine, waited for the lockup, and then printed the dump. It produced an output with multiple processes. A few things stood out. First, the dump contains a fair number of "extra" blank lines; more on that later. One false alarm (I think) was some #doesNotUnderstand: activity in what appears to be the finalization and timer threads. It looks suspiciously like the output from the Process Browser :) The morphic main loop was waiting inside of #interCyclePause: (seems reasonable, except that it's happening for far too long) rather than (as I expected) stuck on a critical section held by one of my other threads. Perhaps most interesting is that the other thread did not appear in the dump. There is a way that it might have exited, but I would expect a logged error that I'm not seeing. Running the offending app and **not** waiting for the deadlock gives a dump that similarly shows multiple processes, some extra blank lines, includes the threads that I expected to see, but does not include the morphic main loop. Wondering whether the stack printing might be exiting early, I tweaked it with some leading/trailing #print:, translated, and rebuilt. The blank lines still appear, but there is no evidence that call stacks were started and not finished. Each process has a start/stop line, and there are no orphaned start lines. Is there a state that's not represented in the dump? Any other ideas? Some suggestions: (1) an obvious header line helps when trying to sort out dumps made at different times (2) it might be helpful to include each process' priority in the dump Finally, re MinGW installation, I think it's possible to edit the path (and other ev's) in win2k using control panel/system/advanced/ev's and edit the variable of interest. Include no extra spaces in the path though, or it won't work??? Anyway, it appeared to work w/o a reboot. Bill Wilhelm K. Schwab, Ph.D. bills(a)anest4.anest.ufl.edu (352) 846-1285
