[Bug] The ever-widening PluggableTextMorph
by Ken Causey 31 Dec '03

31 Dec '03

( PluggableTextMorph on: nil text: nil accept: nil readSelection: nil menu: nil ) extent: 50@100; editString: 'This is some really long text that will hopefully cause the PTM to wrap and a scollbar appear'; hResizing: #shrinkWrap; openInWorld. Now either extend the text or just wiggle the scrollbar and watch the PluggableTextMorph widen and widen. The hResizing: #shrinkWrap seems to lead to this behaviour. Ken

[BUG] Debugger Highlighting still not quite right in 3.6 when browseWithPrettyPrint enabled
by Ken Causey 19 Dec '03

19 Dec '03

I'm still having problems with debugger highlighting even in a 3.6 image upgraded to 5387. The best way I can come up with to give you a repeatable way to see this: 1. Start with a 5387 image like the one at ftp://st.cs.uiuc.edu/pub/Smalltalk/Squeak/3.6beta/Squeak3.6b-5387.zip 2. Go into the preferences and enable browseWithPrettyPrint 3. Open the Package Loader (SqueakMap). 4. File in Celeste Removal. This results in a UndefinedObject methodsFor:? debugger prompt. 5. Browse the stack. Guess I'll file the Celeste Removal issue seperately. ;) Ken

[BUG] BFAV/KCP archive problem
by Tim Rowledge 16 Dec '03

16 Dec '03

I just tried out the BFAV browser on the KCP archive. Somewhere around number 88 it failed because the #timeSent of an entry was nil. I really can't quite work out how this could arise since the mail implementation of #time seems to take some pains to prevent that possibility. A quick hack changing the ArchivePost>timeSent to return 0 if the ivar is nil got me past that initial problem. The MailMessage>time method uses ifError:, a crime for which there is no adequate punishment. Well, maybe an enforced watching of dumb and dumberer? It also failed to load a large number of entries but since BFAV seems to do that regularly I didn't pay much attention. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Strange OpCodes: IXM: Initiate X-rated error Messages

Amen to that. BTW, everyone is welcome to join the review fest going on in the final hours of 3.6alpha by installing the BFAV and reviewing/testing/ commenting something (even if its small). I intend to do some approving tommorrow, so stuff that gets enough loving and is ready still has a chance to get in. Daniel PS.

[BUG] BFAV requires net access to write a response
by Daniel Vainsencher 16 Dec '03

16 Dec '03

I was trying to open as a mail a response I'd written, so that it get put in my Celeste queue for later sending. I think this shouldn't require net access - being able to work offline is an important feature. The following lines show the culprit.

Morph>>Delete
by Jeff Longland 05 Dec '03

05 Dec '03

I'm trying to create a button that will delete a morph named JeffsTestMorph (sublass of Morph). Through inheritance, JeffsTestMorph inherits the delete method does it not? On mouseDown for my button, I have the following: mouseDown: evt JeffsTestMorph delete. But when I click on the button I get MessageNotUnderstood: delete. Could someone tell this Squeak newbie what he's doing wrong? Thanks, Jeff

[ENH][VM] faster image startup
by John M McIntosh 03 Dec '03

03 Dec '03

Make image startup slightly faster. a) Don't rewrite all oops to clear the mark bit, only rewrite the ones that have the mark bit set. b) Don't rewrite all oops to change oops address if the offset is zero which is the case on the mac when the same vm reads a recently saved image because of how the memory map is located. Unknown if this is the case on wintel. c) Don't rescan the entire image a second time to null out compiled methods with an external primitive call, remember those oops on the first scan, then later null out the 320 or so contexts, versus rescaning 260 thousands oops Now one of the 'ugly' things I did here to avoid altering the Interpreter class definition and having 16K of memory sucked up by a global one-time use table is to allocate a local 4096 element Array in ObjectMemory>>initializeObjectMemory: which gets passed to an altered adjustAllOopsBy: which remembers the methods oops that have refer to external primitives as it's looking for Oops with the Mark Bit set. That array with the stored count is returned and at the end of initializeObjectMemory we decide to invoke the old flushExternalPrimitives if the count is >= 4095 or in my testing with the base image since we only have 320 oops that match it means just invoking flushExternalPrimitiveOf: on the remembered oops. At startup time we reduce the CPU time by 8% based on the changes to initializeObjectMemory:, and remove another 4% based on a no-longer required rescan by flushExternalPrimitives. Although these changes reduce powerpc startup time by just a little it should make some noticeable changes for 100MB images, or on machines that are *much* slower. Other changes go into the mac source code to reorganize how the menu bar is manipulated and not to start the 1/60 clock pthread until it's really required. That shaves a bunch of clock time off and now startup is much more snappy. -- ======================================================================== === John M.

Re: (fwd) [Test-Runner Results] Squeak3.6beta latest update: #5411
by Daniel Vainsencher 21 Nov '03

21 Nov '03

Thanks, didn't know the version name was part of the updates.list. Is that definitely linked to the ftp directory name? My scsh script ended up looking like this - *************** #!/usr/bin/scsh -s !# (define versionname (string-drop (last (filter (lambda (s) (string-prefix? "#" s)) (run/strings (| (curl -s "http://update.squeakfoundation.org/external/updates/updates.list") (tr "\r" "\n"))))) 7)) (define ftpdir (string-append "ftp://ftp.squeakfoundation.org/official-dist/" versionname "/")) (define imagename (string-drop-right (last (string-tokenize (last (run/strings (curl -s ,ftpdir))))) 4)) (run (wget ,(string-append ftpdir imagename ".zip"))) (run (unzip -o ,(string-append imagename ".zip"))) (run (squeak -memory 64M ,(string-append imagename ".image") runTests.st)) ****************** where runTests.st is a short script that loads and runs Markus' code. scsh is currently my favorite shell language (which isn't hard, I hate most of them ;-).

Re: Erlang (was: Re: Generics)
by Blaine Buxton 10 Nov '03

10 Nov '03

Hey, I've been reading up on Erlang myself. They have an approach where everything is a process and you send messages to these processes. Just imagine having a separate process for each Squeak object. They argue that processes should be as easy to create as objects. You would think this would kill performance, but actually, the systems they have written in it scale very well (the web server they wrote in Erlang can handle 10x the capacity of a Apache server, if I remember correctly). They also boast numbers of 99.99999% availablity for the Ericsson switch that was written in mostly Erlang. Now, those boasts are what got me interested. It is a functional language and they are big on no mutable state like most functional languages. They argue that Erlang makes multi-processing easy and in fact easier than single process systems. They seem very anti-OO on their list, but I have found that the whole process thing maps very well to objects. But, I haven't gotten that far. It just seems they have been scarred by the {} crowd and static typed OO systems. I haven't had a whole lot of time to really get much deeper than that. I bought the book and have been working through some of the examples. They do a lot with pattern matching and it's made me think about certain programming topics differently. I know I wasn't the person you were asking for the answer, but I thought I'd chime in. ------------------------------------------------ Blaine Buxton My Amps: Smalltalk, Lisp, and Ruby http://www.blainebuxton.com >From: Daniel Vainsencher <danielv(a)netvision.net.il> >Reply-To: The general-purpose Squeak developers >list<squeak-dev(a)lists.squeakfoundation.org> >To: The general-purpose Squeak developers list ><squeak-dev(a)lists.squeakfoundation.org> >CC: squeak-dev(a)lists.squeakfoundation.org >Subject: Erlang (was: Re: Generics) >Date: Mon, 29 Sep 2003 13:38:37 +0300 > >Hi Richard. > >"Richard A.

[ENH] SMTPonAlternatePort
by black＠cse.ogi.edu 04 Nov '03

04 Nov '03

from preamble: "Change Set: SMTPonAlternatePort Date: 5 September 2003 Author: Andrew P. Black Added logic to allow mail to be sent to an SMTP server that operates on an alternate port, i.e., on other than port 25. The syntax used is to permit ':<number>' to follow the IP address that is typed by the user. The test is that this changeset made it to the list!!"!
