WeakSet but no WeakIdentitySet?
by Igor Stasenko 26 Aug '23

26 Aug '23

Hello, i need to keep a bunch of CompiledMethods in WeakSet, but i am a bit afraid, that it wont work as i want to, because of CompiledMethod>>= implementation, because a code, which i currently writing doesn't changing a method's bytecode, but changing its trailer instead, and so, this could lead to undesirable effects.. If i could have a WeakIdentitySet... Meanwhile, i think i have nothing else, but just use a degenerate WeakIdentityKeyDictionary , with methods in keys and nils in values. :( -- Best regards, Igor Stasenko AKA sig.

tracking issues with the "squeak-object-memory" repo
by Craig Latta 17 Aug '23

17 Aug '23

Hi all-- The Squeak board is trying an experiment. We've created the GitHub repo "squeak-object-memory", and are curious to see how useful it is to track issues there. With this message, I can close the first issue[1]. :) Please bring on the other thirty gazillion of them... thanks!

veryDeepCopy, ImageSegments, and actionMaps
by Ned Konz 17 Aug '23

17 Aug '23

Any Object can have dependents whether or not it has an instance variable to keep track of them (these are kept in the DependentsFields class variable of Object). The only class that keeps its own dependents is Model. Any Object can have an actionMap. These are supplied by EventManager class by default, and are stored in the ActionMaps class variable of EventManager. The only class that keeps its own action maps is Morph. When we veryDeepCopy an object we also copy the global dependents (see DeepCopier>>fixDependents). However, we don't copy the actionMap in those cases where it's held by the EventManager class. When we file out an object that uses DependentsFields out into an ImageSegment, we also file out the dependents (see ImageSegment>>dependentsSave:) if it's in a project. We do this by adding a project parameter called #GlobalDependentsInProject. However, we don't file out the actionMap in those cases where it's held by the EventManager class. My question is this: should we fix these behaviors (copying and serialization) to include these "global action maps" just like we already include the "global dependents"? Or should we discourage the use of the "global action maps"? -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE

Review Request: mcSlips
by christoph.thiede＠student.hpi.uni-potsdam.de 21 May '23

21 May '23

Any fundamental objections before I would merge this into the Trunk? :-) =============== Summary =============== Change Set: mcSlips Date: 16 January 2022 Author: Christoph Thiede This changeset integrates the slip detection mechanism, previously only known from the domain of changesets, into the Monticello system. When users save a new version, it will automatically notify them about any possible slips and let them decide whether to browse them first or proceed the saving. Users can also scan their patch for slips manually by invocating the item from the patch list menu. The value of the preference #checkForSlips is still honored for the automatic detection, and the description of that preference is updated to mention the new usage. =============== Postscript =============== "Postscript:" (Preferences preferenceAt: #checkForSlips) helpString: 'If true, then whenever you file out a change set or save a Monticello version, it is checked for ''slips'' and if any are found, you are so informed and given a chance to open a browser on them.'. =============== Diff =============== CompiledMethod>>hasReportableSlip {testing} · ct 1/15/2022 22:32 (changed) hasReportableSlip "Answer whether the receiver contains anything that should be brought to the attention of the author when filing out.

Review Request: stylePackageScripts.2.cs
by christoph.thiede＠student.hpi.uni-potsdam.de 18 May '23

18 May '23

Please give me a short feedback on whether you agree with the idea of this change (PackageInfo scripts are no longer instances of StringHolder). If there is no objection, I will try to merge this into the Trunk after a week or so. :-) ["stylePackageScripts.png"] Best, Christoph =============== Summary =============== Change Set: stylePackageScripts Date: 22 November 2021 Author: Christoph Thiede This change set enables syntax highlighting for package scripts ({preamble,postscript}{, of removal}). To achieve this, the instance variables in PackageInfo are converted to hold plain strings or texts rather than StringHolders, and the client (Monticello) is reponsible itself for displaying them to the user and storing them back into the package. Note the postscript which converts all PackageInfo instances in the image. =============== Postscript =============== "Postscript: Eliminate StringHolder script in PackageInfos" PackageInfo allSubInstancesDo: [:packageInfo | #(preamble postscript preambleOfRemoval postscriptOfRemoval) do: [:sel | (packageInfo instVarNamed: sel) ifNotNil: [:stringHolder | packageInfo instVarNamed: sel put: stringHolder contents]]]. =============== Diff =============== MCWorkingCopyBrowser>>editLoadScripts {morphic ui} · ct 11/22/2021 16:05 (changed) editLoadScripts | arg | self hasWorkingCopy ifFalse: [^self]. arg := UIManager default - chooseFrom: #('edit preamble' 'edit postscript' 'edit preambleOfRemoval' 'edit postscriptOfRemoval') + chooseFrom: {'edit preamble' translated.

Exception reraiseFrom: (needs review)
by Eliot Miranda 02 Feb '23

02 Feb '23

Hi All, Hi Levente, Jaromir, and Context hackers, find attached a change set which supports re-raising a fatal exception, caught inside a critical section, outside the critical section. This is a key facility for debugging systems such as Croquet. I expect it'll also be useful in delimited continuation contexts such as Seaside. The facility is closely related to Context>>copyTo: and Context>>copyTo:bottomContextDo:. The main method is Exception>>copyForReraiseTo: aContext. This implementation is higher quality than Context>>copyTo:[bottomContextDo:]. It copies the stack and it also copies blocks that are created on the copied stack. So the copied stack correctly copies blocks, and hence exception handlers. I'm thinking of adding this to trunk. I would like it to be reviewed carefully before I do so. Both implementation and selector names need reviewing, and tests and more use cases would be nice (I have a use case in Virtend/Croquet). Here's an example usage: | sender error | sender := thisContext sender. Mutex new critical: [[nil new] on: Error do: [:ex| error := ex copyForReraiseTo: sender]]. error reraiseFrom: thisContext A simpler usage would be | home error | home := thisContext. Mutex new critical: [[nil new] on: Error do: [:ex| error := ex copyForReraiseTo: home]]. error outer This doesn't work because ProcessorScheduler>>#debugContext:title:full:contents: (et al) contains self assert: [thisContext hasSender: aContext] and hence we have to stitch the copied stack into the current stack via aContext privSender: signalContext. thisContext privSender: aContext. self outer inside Exception>>reraiseFrom: aContext Maybe adding a flag to Exception and avoiding that assert when the exception is "in reraise mode" is better. I don't know. Given that the main worker method, Context>>#copyTo:atEachStep:, is better than Context>>copyTo:[bottomContextDo:]., these two could be reimplemented in terms of it, e.g.: Context>>copyTo: aContext ^self copyTo: aContext atEachStep: [:originalContext :copiedContext| originalContext sender == aContext ifTrue: [copiedContext privSender: nil]] Context>>copyTo: aContext bottomContextDo: aBlock ^self copyTo: aContext atEachStep: [:originalContext :copiedContext| originalContext sender == aContext ifTrue: [copiedContext privSender: nil. aBlock value: copiedContext]] _,,,^..^,,,_ best, Eliot

FormInspector, or also: Text>>#= and its consequences
by Thiede, Christoph 12 Jan '23

12 Jan '23

Hi all, is there any old thread about the design discussion of how Text>>#= works? (It does not consider attributes for quality.) Has this decision ever been questioned? Naively and without an overview of any existing components that could rely on this implementation, I would like to question it. Why should 'foo' asText allBold be equal to 'foo' asText addAttribute: TextURL new? With the same logic, we could also say that two dictionaries are equal iff they have got the same keys ... There is even a concrete client in the Trunk suffering from this design decision: Marcel's new FormInspector (and analogously, MorphInspector). It uses TextFontReference with a FormSetFont to display a screenshot right in the inspector pane. Unfortunately, the pane is never updated automatically because even if the screenshot changes, the text morph thinks the old text would equal the new one. I'd like to fix that without hacking any workaround into the inspectors. Even though this inspector implementation is a bit unusual, in my opinion, it shows that the current Text >> #= implementation might not be a perfect solution. I'm looking forward to your opinions. Best, Christoph

Should I put my unofficial V3 versions of Squeak 5.2 and 5.3 on files.squeak.org?
by David T. Lewis 28 Dec '22

28 Dec '22

A couple of years ago, I put a copy of a Squeak 5.2 image in V3 object memory format on the squeakvm.org server, and I linked to it from the project page at http://www.squeaksource.com/TrunkUpdateStreamV3. That link has gone dead, and I think I recall someone noticing it a recently. I still have the files, should I put them somewhere on files.squeak.org? I was thinking of putting them under the "various_images" folder: files.squeak.org/various_images/squeak_V3_images/ I also have a V3 image that is up to date with the Squeak 5.3 release, so I could put that on line as well. These images will run under an up-to-date interpreter VM or a Cog VM. They may be of interest to people doing VM work, benchmarking, or as a reference to understand the image-side differences between Spur and V3. Dave
