[FIX] TextMorphBuglet
by bparsia＠email.unc.edu 04 Aug '04

04 Aug '04

from preamble: "Change Set: TextMorphBuglet Date: 1 December 2003 Author: Bijan Parsia Another in a series of microfixes. This showed up when using the codeProvenance button to toggle colorPrinting from prettyPrinting. Since the actually characters didn't change, the display wouldn't update until you went to another method, or cycled through some other display mode. This fix follows the advice in Text>>=. I expect it'll slow somethings down, especially for complex texts (e.g., with embedded morphs). It may be better to change how this test logic works, but now, at least, the behavior is correct."!

[ENH] UsableSiblingInstanceFix-nk
by Ned Konz 04 Aug '04

04 Aug '04

from preamble: "Change Set: UsableSiblingInstanceFix-nk Date: 11 October 2003 Author: Ned Konz Morph>>usableSiblingInstance was always adding the created sibling to the World, even though many of its callers would turn around and immediately add the result to other morphs or delete them from the World. This change set makes #usableSiblingInstance not add the newly created Morph to the World. This makes several uses of #usableSiblingInstance more bug-free and efficient. "!

Mac VM 3.7.1b2 (for testing)
by John M McIntosh 04 Aug '04

04 Aug '04

I've pushed a Mac VM 3.7.1b2 for testing to http://homepage.mac.com/johnmci/ Squeak 3.7.1Beta2.app.sit It contains: 3.7.1b2 a) JPEG READER WRITER Usage of Apple '-fast' uncovered a source code issue, initialization routines for internal jpeg plugin were not returning true or false, before this was kinda of considered as returning true? But when compiled with -fast it's zero, meaning the inialization failed, but that is bogus. b) Use of "-fast" apple gcc 3.3 compiler option, improves sends by significant % c) Broke high bit ascii macroman in 3.7.0bx. On EventKeyUp/EventKeyDown you get the UniCode On EventKeyChar you now get the UniCode->MacRoman translated character. For multi-byte character input you get EventKeyDown/EventKeyChar/EventKeyUp for each unicode character coming from the input sequence. Please note that I've a 3.7.1b3 pending due to window open issue in os-x 10.3.2, but please try this VM for speed/performance and correctness. OS-9 Users please note I did not rev the os-9 binary because these are os-x specific issues being fixed at this time. -- ======================================================================== === John M.

[BUG][FIX] WeakGCFix-wbk
by bryce＠kampjes.demon.co.uk 03 Aug '04

03 Aug '04

from preamble: "Change Set: WeakGCFix-wbk Date: 21 March 2004 Author: Bryce Kampjes Weak references can leave dangling pointers if the weak object is in old space and it points to a new space object. The problem occurs when the new space object is incrementally collected but the old space weak object remains. The weak object now has a dangling pointer to where the new space object was. This change set adds a little code to ObjectMemory>>sweepPhase so that it will finalise any weak rootTable objects. There is still the chance that an interpreter variable may contain a pointer to a weak object. However interpreter variables have very specific uses. I'm not sure if they should be checked for weak references. "!

from preamble: "Change Set: ExceptionDialogs-avi Date: 31 August 2003 Author: Avi Bryant Adds Notifications for #inform:, #confirm:, and #confirm:orCancel:. By default these still use PopUpMenu, but they could be caught and dealt with more appropiately in different UI contexts."!

[BUG] Cannot open files in a Mac volume's root
by Bert Freudenberg 28 Jul '04

28 Jul '04

The culprit seems to be "MacFileDirectory class>>isAbsolute:" which answers false if no colon is found inside the file name - which is the case for a volume name. To reproduce: Open a file list, select a volume (scroll all the way up in the directory pane), and select a file in that volume (not in a subdirectory). You may have to buy a Mac first and install Squeak. - Bert -

[BUG]FileList connect to ftp password infinite loop
by Tim Rowledge 28 Jul '04

28 Jul '04

5905 image. Try to connect to UpdatesAtSqF, get asked for password. Cancel. 'Would you like to try another password?' -> give up. Notifier 'Error: Login failed'. Abandon. Goto 'get asked for password'. Attempts to debug fail because although the interrupt key gets a notifier, 'Debug' dumps you right back into the loop instead of in a Debugger! Outrageous! tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Useful random insult:- Pedaling real fast, but not getting anywhere.

[bug] stack overflow crashes Squeak.
by Michael van der Gulik 06 Jul '04

06 Jul '04

Hi all. If you make a naive class that calls itself: Forkbomb>>forkbomb ^ self forkbomb. Squeak 3.5 on Debian linux will eventually crash, leaving a huge stack dump in the terminal. Okay; it's really my fault for making such a stupid class, but I'm playing around with proxied objects, message sends etc and it's happening quite often while I'm debugging. Is there a way to limit the invocation stack to a sane level of deepness, after which a process/thread (whichever is Squeak terminology) gets suspended and an error thrown? Same probably applies to number of processes made by a thread. mikevdg.
