3.6a - SystemNavigation instance?
by Ingo Hohmann 25 Aug '03

25 Aug '03

Hi All, is there a glaobal instance of SystemNavigation? Or do I have to create my own whenever I want to use it? I'd say this should be in the class comment, otherwise "Error: Method Deprecated: Use SystemNavigation>>confirmRemovalOf:on: instead" is not too helpful to a newbie. Kind regards, Ingo

[BUG] infinite recursion on PluggableTextMorph>>extent:
by ned＠bike-nomad.com 14 Aug '03

14 Aug '03

I've noticed this recursion a few times. I chose a method in a RB and asked the RB to "rename method", and got this. I have the RB and Skins packages loaded. 20 May 2003 12:16:08 pm VM: Win32 - Squeak3.4 of 1 March 2003 [latest update: #5170] Image: Squeak3.6alpha [latest update: #5184] PluggableTextMorph>>extent: Receiver: a PluggableTextMorph(2667) Arguments and temporary variables: newExtent: 296@18 Receiver's instance variables: bounds: 2@20 corner: 298@38 owner: a SystemWindow(2881) submorphs: #(a TransformMorph(1395)) fullBounds: nil color: Color transparent extension: a MorphExtension (1334) [other: (layoutFrame -> a LayoutFrame) (lay...etc... borderWidth: 2 borderColor: #inset model: a MethodNameEditor slotName: nil open: false pinSpecs: nil scrollBar: a ScrollBar(2786) scroller: a TransformMorph(1395) retractableScrollBar: false scrollBarOnLeft: false getMenuSelector: nil getMenuTitleSelector: nil scrollBarHidden: nil hasFocus: false textMorph: a TextMorphForEditView(1183) getTextSelector: #selector setTextSelector: #selector: getSelectionSelector: nil hasUnacceptedEdits: false askBeforeDiscardingEdits: true selectionInterval: (1 to: 0) hasEditingConflicts: false PluggableTextMorph>>resetExtent Receiver: a PluggableTextMorph(2667) Arguments and temporary variables: tempSelection: (1 to: 0) Receiver's instance variables: bounds: 2@20 corner: 298@38 owner: a SystemWindow(2881) submorphs: #(a TransformMorph(1395)) fullBounds: nil color: Color transparent extension: a MorphExtension (1334) [other: (layoutFrame -> a LayoutFrame) (lay...etc... borderWidth: 2 borderColor: #inset model: a MethodNameEditor slotName: nil open: false pinSpecs: nil scrollBar: a ScrollBar(2786) scroller: a TransformMorph(1395) retractableScrollBar: false scrollBarOnLeft: false getMenuSelector: nil getMenuTitleSelector: nil scrollBarHidden: nil hasFocus: false textMorph: a TextMorphForEditView(1183) getTextSelector: #selector setTextSelector: #selector: getSelectionSelector: nil hasUnacceptedEdits: false askBeforeDiscardingEdits: true selectionInterval: (1 to: 0) hasEditingConflicts: false PluggableTextMorph(ScrollPane)>>showScrollBar Receiver: a PluggableTextMorph(2667) Arguments and temporary variables: Receiver's instance variables: bounds: 2@20 corner: 298@38 owner: a SystemWindow(2881) submorphs: #(a TransformMorph(1395)) fullBounds: nil color: Color transparent extension: a MorphExtension (1334) [other: (layoutFrame -> a LayoutFrame) (lay...etc... borderWidth: 2 borderColor: #inset model: a MethodNameEditor slotName: nil open: false pinSpecs: nil scrollBar: a ScrollBar(2786) scroller: a TransformMorph(1395) retractableScrollBar: false scrollBarOnLeft: false getMenuSelector: nil getMenuTitleSelector: nil scrollBarHidden: nil hasFocus: false textMorph: a TextMorphForEditView(1183) getTextSelector: #selector setTextSelector: #selector: getSelectionSelector: nil hasUnacceptedEdits: false askBeforeDiscardingEdits: true selectionInterval: (1 to: 0) hasEditingConflicts: false PluggableTextMorph(ScrollPane)>>hideOrShowScrollBar Receiver: a PluggableTextMorph(2667) Arguments and temporary variables: Receiver's instance variables: bounds: 2@20 corner: 298@38 owner: a SystemWindow(2881) submorphs: #(a TransformMorph(1395)) fullBounds: nil color: Color transparent extension: a MorphExtension (1334) [other: (layoutFrame -> a LayoutFrame) (lay...etc... borderWidth: 2 borderColor: #inset model: a MethodNameEditor slotName: nil open: false pinSpecs: nil scrollBar: a ScrollBar(2786) scroller: a TransformMorph(1395) retractableScrollBar: false scrollBarOnLeft: false getMenuSelector: nil getMenuTitleSelector: nil scrollBarHidden: nil hasFocus: false textMorph: a TextMorphForEditView(1183) getTextSelector: #selector setTextSelector: #selector: getSelectionSelector: nil hasUnacceptedEdits: false askBeforeDiscardingEdits: true selectionInterval: (1 to: 0) hasEditingConflicts: false --- The full stack --- PluggableTextMorph>>extent: ...etc...

Does anyone have code (or is there any in the image) which, given a string, returns whether or not that string is a syntactically valid email address? Thanks.

RE: BFAV email prefix?
by Brent Vukmer 12 Aug '03

12 Aug '03

Guys, it's like you're reading my mind (or the BFAV Swiki pages... :) ) Here's a fairly detailed response: [ BFAV noise on squeak-dev ] I really want to get the BFAV traffic onto a separate "bug-fixes-archive" list on squeakfoundation.org, soon! I need Goran's help setting that up on the squeakfoundation server. [ BFAV + bug reports + posting updates ] I really want to make the BFAV cover the whole process, from creating a bug report to posting an update to the FTP server. The BFAV will have a tabs for "unreviewed", "reviewed", "approved" and "updates" and users will be able to drag-and-drop posts from one tab to the next, with the appropriate side-effects. I have put the beginnings of bug-report creation functionality into the CommentNotePad. I need to enhance the CommentNotePad so that a bug report has all the required info (VM version, image version, installed SM packages, etc.). As far as viewing bugs goes, you should be able to point the BFAV at http://swiki.gsug.org/sqbugs right now. I'm not interested in building a web interface for creating bug reports; volunteers are welcome! [ Bug Fixes Archive Server ] The BugFixArchive-Model package is very close to being able to do this, as Daniel pointed out. I'm going to look at the code that Bert's image is using and include the functionality that I don't have yet. The new Bug Fixes Archive server will parse the canonical .mbox file ( the one available for download from squeakfoundation.org ) into individual .txt files. We will use Apache to serve up the static .txt files. BTW, for the near term, I'm going to continue to use SMTP to populate the archive. I've thought seriously about using other means -- for example, doing an HTTP POST -- but mail is very simple and robust, and I think it's best to stick with it for now. I'm not interested in building a web interface to display the archive's contents a la http://swiki.gsug.org/sqfixes ; volunteers are welcome! [ Client-Server/Database ] I like keeping the queries local. In a sense, the local BugFixArchive object *is* a database, in that it has fairly extensive sorting/querying capabilities, and we can always add more. I also really like that the BFAV creates a local repository with all of the .txt files. If the Bug Fixes Archive server goes down, I still have my local repository to work with. I'm really interested to find out how much this off-line capability matters to other people... I've thought about using Magma, actually. I'd want to keep the local repository synced with the server repository, for working offline, and I would want the BFAV user to not have to any work to administer the Magma database. [ Package-Specific Archive ] The BugFixArchive-Model package already supports this; you can point a BugFixArchive object at whatever update URL you choose. I need to do a little more work to support posting to a package-specific archive.

The change set merely renames the really hard to remember method #expungePreferenceNamed: to #removePreference: in order to be consistent with #addPreference:. - Andreas

[FIX] Event unregistering fix
by Roel Wuyts 09 Aug '03

09 Aug '03

Found a small bug when unregistering events: the collection of keys is being modified while being enumerated, so some keys are skipped. Did not add a unit test for this, since I don't really know how to make one for this (adding enough items would maybe show it, but that is not a good reproducable test). Anyhow, the fix is attached. Can you have a look, John? -- Roel Wuyts Software Composition Group roel.wuyts(a)iam.unibe.ch University of Bern, Switzerland http://www.iam.unibe.ch/~wuyts/ Board Member of the European Smalltalk User Group: www.esug.org
