[UPDATES] 25 for Squeak3.7alpha
by dway＠riskmetrics.com 04 Nov '03

04 Nov '03

The last week's batch of approved items, including 9 KCP changesets. (There were two KCP changesets named KCP103 for some reason... I renamed one to KCP102-5 (102.5).) - Doug ------------------------------ 5502KCP102vmFromSystDict -- stephane ducasse -- 27 June 2003 Define a new class SmalltalkImage that represents all the SystemDictionary behavior related to SmalltalkImage management. Following Tim suggestion this class will merge all the aspects of VM+Image management. This is the first changeset of a long series. v3: SmalltalkImage current v4: edited for current image (2 conflict) -- md v5: fixed errorReportOn. 5503KCP102-5newInitPattern -- Noury Bouraqadi -- 16 September 2003 MD: This changeset was generated by filing in Noury's original into the latest 3.7 plus the KCPs (83, 102, 104-107). The postscript was removed. original comment: Partially replaces KCP-102 since it introduces the pattern new-initialize and does not alter variable objects creation (i.e. definition of #new: remains unchanged). Also, delete all obsolete definitions of new and initialize. This latter task is performed using classes provided by classes of the ObsoleteMethodTest hierarchy, that are removed afterwards (see the postscript)." 5504KCP103vmProfiling -- stephane ducasse -- 24 September 2003 This changeset moves VM profiling primitives from SystemDictionary to SmalltalkImage. Simple. v3: SmalltalkImage current" 5505KCP104vmStatistic -- stephane ducasse -- 24 September 2003 This changeset move some VM report utilities from systemDictionary to SmalltalkImage. v3 SmalltalkImage current" 5506KCP105systemAttributes -- stephane ducasse -- 22 October 2003 Extract from SystemDictionary the fonctionality to get the parameters passed on the command line and related. v3: SmalltalkImage current v4: fixed some conflicts and comments -- md" 5507KCP106moveModuleToStIm -- stephane ducasse -- 24 September 2003 Extract form SystemDictionary all the primitives working on the modules and define them on the class SmalltalkImage. v3: SmalltalkImage current" 5508KCP107imageNameToStImage -- stephane ducasse -- 24 September 2003 Extracted image path and name to move that in SmalltalkImage v3: SmalltalkImage current v4: Fixed imageName: v5: fixed one conflict -- md" 5509KCP108globalFlapTab -- stephane ducasse -- 27 September 2003 Deprecate globalFlapTabOrDummy: from Utilities. The method comment says that for it stayed for possible existing imageSegments but we should move forward " 5510MorphExample -- Karl Ramberg -- 26 October 2003 The step method caused a walk back. Kind of silly to have a class called MorphicExample that don't work. Added a simple class comment." 5511DebugCreateMethods-nk -- Ned Konz -- 12 February 2003 This little change set adds a 'Create' button to debuggers that pop up on MNU's. This button writes a stub method containing a halt, then proceeds the debugger (which will stop at the halt). You can then edit the source of the method. Also adds an 'implement in...' submenu to the debugger's call stack's contextual menu (only for #doesNotUnderstand: messages)." 5512ParenBlinking -- Avi Bryant -- 8 October 2003 md: reposted as real changeset. Avi writes: This has been on SqueakMap forever, but I figured with the new BFAV and so on it might be worth posting it as an ENH, in the hopes that it'll actually make it into the image. This makes two changes to the ParagraphEditor: 1. upon typing ), }, or ], the matching (, {, or [ will be made bold until the next keystroke 2. the meanings of return and control-return are switched (ie, auto-indent is the default) I have had this changeset loaded in every image I've used for the last year and a half, with no ill effects. I think it makes the ParagraphEditor significantly more useful for writing code (which is, after all, what most of us use ParapraphEditor for most of the time). If people want change 1 without change 2, I'm happy to introduce a preference that controls that (although I personally think of auto-indent as something any good text editor does, and can think why you wouldn't want it). Separating them into two changesets is more difficult, however, since they both need to modify #dispatchOnCharacter:with:. Cheers, Avi 5513ActionSequenceFix-nk -- Ned Konz -- 9 October 2003 9 October: - removed WeakActionSequence>>isValid to avoid confusion. - added Object>>removeActionsSatisfying: 5 August: re-posted without Roel's fix. 30 July: first version. - Fixes a bug that made it impossible to say: someObject when: #something evaluate: (MessageSend ...) because MessageSend didn't understand #isValid 5514DeclareInstVar -- Lukas Renggli -- 17 July 2003 md: reposted in a normal ENH form (gzip-compressed, MIME atachement) Adds the menu-item 'declare instance variable' to the list that is displayed when the parser encounters an undeclared variable. The generation of the menu has been slightly altered to allow other extensions more easily." 5515MoreCursorConstants-JMM -- johnmci(a)smalltalkconsulting.com -- 21 October 2003 I noticed that some of the resize cursors are built on the fly, versus being constants. These build operations occur when moving within the browser window and on my machine take 8ms and cause a noticable flicker Usage of constants like the other cursor constants make movement within the browser windows much smoother " 5516SlowResizeCPU-JMM -- johnmci(a)smalltalkconsulting.com -- 21 October 2003 In the browser window CPU usage would go to 100% when we enter the resize pane area, or resize the pane. This was due to zero step time for NewHandleMorph a subclass of HandleMorph which looks at cursor location to change the cursor shape. Change step time to 10 ms in HandleMorph to solve this. Then issue is at actual resize time CPU usage goes to 100%. Issue in resize retangle logic (three places) where it watchs the cursor. Change to delay for 10 ms between cursor lookups" 5517SymbolFindInterned 5518UpdatingMenuRefreshFix-nk -- Ned Konz -- 30 Sept 2003 This CS keeps updating menu item morphs with checkboxes from repeatedly redrawing. version 2: fixes non-check boxes too. version 3: MCP changed == nil to isNil, this change does this, too (md). 5519InterProcessSignaling-svp -- Stephen Pair -- 21 September 2003 [re-posted by Ned Konz as an attached changeset] The attached file-out is an improved inter-process signaling mechanism. It adds a method #signal: to Process that accepts an exception as its argument. It will signal the exception in the context of the receiver. If the receiver is currently suspended (i.e. not on a list), the exception will not get signaled until the process is resumed. If the receiver is currently blocking on a Semaphore, this method will return the receiver to a non-blocked state and the process will resume with the exception being signaled. If that exception is handled and resumed, the process will return to a blocked state if the semaphore does not have any excess signals. So, as Ned pointed out, you could use this to timeout a process that is waiting on a Semaphore with an exception. It might look something like this. | sem proc | sem := Semaphore new. proc := [sem wait] newProcess. proc resume. (Delay forSeconds: 5) wait. proc signal: (Error new messageText: 'hey wake up!'; yourself). I think this has the potential for a multitude of uses. I can imagine extending the process browser such that you can right click and send a variety of common signals to a process. - Stephen 5520FixSharedQueue -- Nathanael Scharli -- 18 June 2002 This fixes two bugs associated with (partially) flushing a SharedQueue. The problem was that the sempahore that is used to block a reader when the queue is empty did not get adjusted right." 5521MoreComments -- Karl Ramberg -- 29 October 2003 Comments to several morhic classes." 5522TextWSqueakLineEndings-nk -- Ned Konz -- 16 September 2003 This somewhat inefficient method should replace the incorrect one that I posted as part of a fix to the Refactoring Browser earlier. 5523alphaRules-bf -- Bert Freudenberg -- 28 October 2003 Readability fix: Uses symbolic constants instead of numbers to denote alpha blend rules. Otherwise, Form>>paintAlpha and Form>>blendAlpha would appear unused, when in fact, they are." 5524ShrinkingSelCursorEnd -- torge husfeldt -- 31 October 2003 torge husfeldt wrote: BTW, i found a small bug wrt #cursorEnd: in boundary cases and an oddity with printIt: Try selecting a smalltalk expression right-to-left and then hit <yourModifier>-p. Fixes to both attached. md: better name, preamble, mailed to the list in the correct way, so it does not get lost" 5525MoviesCleanup -- Adam Spitz -- 30 July 2003 Moves some classes and methods into the Movies-* categories. Still leaves the 'add movie clip player' menu item in PianoRollScoreMorph; there might be some kind of general menu-registration mechanism coming soon, so we'll deal with that then." Smalltalk organization classifyAll: {#BlobMPEGMorph. #MovieClipEndMorph. #MovieClipStartMorph. #MovieFrameSyncMorph. #MoviePlayerMorph. } under: 'Movies-Player'.

"We don't want these methods to be part of the Tools-FileList package; then FileList would depend on Movies, which makes no sense."

MPEGMoviePlayerMorph class organization renameCategory: '*Tools-FileList-registering' toBe: 'registering'. MPEGPlayer class organization renameCategory: '*Tools-FileList-file suffixes' toBe: 'file suffixes'. 5526BorderedMorphComments -- Karl Ramberg -- 27 October 2003 Comments for BorderedMorph and subclasses and AlignmentMorph" <This automated message brought to you by the UpdateIncorporationTool.> <See the UpdateIncorporationTool package on SqueakMap for details.>

Re: [crash] Squeak crash on MasOS 10.3 (panther)
by Raymond 04 Nov '03

04 Nov '03

Hi Joshua, my hypotheses were wrong, the problem is still there...! > Which version of the image are you running? I'm curious if it is > related to the crashes under Linux with a 3.7-5501 image (see the > "Crash during update?"). For now Squeak crash with image 3.6 and VM 3.5.2beta5 and VM 3.6.0Beta3. I think it is an MacOS version problem because I changed the system last weekend, before that there were no problem with these image and vm. Or, may be, a VM problem too. > Does it crash immediately when you try to start Squeak? If not, > what triggers it? In general it crash in the first one to three minutes of using...I was browsing code...I don't know precisely what triggers it ? Raymond

[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!!"!

[BUG][FIX] PostscriptCharacterScanner DNU #setAlignment: ( [sm] )
by Bryce Kampjes 04 Nov '03

04 Nov '03

This fixes the DNU but doesn't centre the printed postscript text. This bug is important if printing is important for StackMorphs. A simpler fix would be to remove the expression (paragraph text attributesAt: offset forStyle: paragraph textStyle) do: [:att | att emphasizeScanner: self]. from PostscriptCharacterScanner>>setTextStylesForOffset:offset. emphasizeScanner: just calls setAlignment:. Given the proposed fix doesn't change the printed postscript, a simpler option might be better. It's possible that there is another bug or missing feature somewhere else in the printing code. I don't know enough about StackMorph's, postscript, or Squeak's printing to take this any further.

[FIX] ClassVarsFix-petervr-v2
by Peter van Rooijen 04 Nov '03

04 Nov '03

I added some SUnit tests to demonstrate the bug and give credibility to the fix. Only two of the tests fail in an unfixed image. The rest serve as regression tests. All the tests pass after the fix is installed. I added the tests as a file-out. I tried filing it into a change set, but doing that lost the class comment. Cheers, Peter > from preamble: > > "Change Set: ClassVarsFix-petervr-v2 > Date: 9 October 2003 > Author: Peter van Rooijen > > fixes the lookup of class variables. > previously, inherited class variables > did not shadow other shared variables. > > v2 - minor improvements"!
