Packaging the programming tools
by Andreas Raab 02 Aug '05

02 Aug '05

Folks - I've been working on detangling the current tool set from the rest of the system since I wanted to be able to replace the current tool set with something more appropriate for Tweak. It turns out that with a little restructuring of responsibilities this isn't all that hard and so I'm happy to announce the probably only Squeak image in the world which has no programming tools whatsoever (!): http://www.impara.de/~andreas/iSqueak/3.8/NoTools.zip [6.3MB] If you grab this image you will find that you won't be able to open a browser, a change sorter, workspace etc. not even a debugger[*1] simply because none of these tools are present. [*1] Try browsing the sender of some message or a class - you will very quickly notice why I don't like the usage of "AppRegistry default" since it raises completely needless errors when for example trying to browse a class -- compare this with the notifier you get when trying to browse a selector which uses ToolSet's interpretation of "proper" AppRegistry behavior. However, since this is not very interesting, you can just load the standard tools package from http://www.impara.de/~andreas/iSqueak/3.8/Tools-ar.17.mcz [450k] install and use it. And when you're tired of it, simply unload it from Monticello[*]. Needless to say, the tools package does not leave any obsolete classes or undeclared references behind, it comes and goes cleanly. [*] After unloading execute the code in the left hand panel - it turns out that #unload is not executed when unloading packages from Monticello (we *really* need to fix this!) probably because the #unload method is removed before the class. But wait, there is more! Since the current tools package is somewhat messy and depends directly on Morphic and MVC I decided to build an alternative which exclusively depends on ToolBuilder. It's called the "PlusTools" (all the names have a "Plus" in the name, e.g., FileListPlus, TestRunnerPlus, ClassBrowserPlus, DebuggerPlus...) and loadable from: http://www.impara.de/~andreas/iSqueak/3.8/PlusTools-ar.16.mcz [300k] And of course, you can load and unload both tool sets at the same time if you'd like to. Note that the point of this exercise is not only to be able to replace the tools for Tweak - it is equally to show that a Squeak system can easily come without *any* specific tool support, squeakmap, even monticello (I only left MC in the image because you'd have to load it anyway to get to the tool sets) just as long as you have a way of loading code (e.g., compiler and change management). Therefore there is really no need whatsoever to put all of the programming tools into a "basic" Squeak image. And finally, the PlusTools should be helpful for further detangling work as they depend on ToolBuilder and not on Morphic or MVC (there might still be a few remnants but that's easily fixable). For those of you interested, here are the major changes that I did to make the above possible: * Refactoring of ChangeSet and ChangeSorter - all of the actual change set related stuff had to be moved out of ChangeSorter and ChangeSet itself had to be moved over to the System package and out of Tools. * Moving of the breakpoint, tallying, file contents browser (diff etc) out of the Tools (right now all of these are in System) * Introduced FileServiceRegistry to avoid abuse of FileList * Introduced ToolSet AppRegistry to support various tool sets I also had to do some significant shuffling around between packages to get everything in order and (un-)loadable but most of these changes were non-invasive. If you are interested the full repository is also available at: http://www.impara.de/~andreas/iSqueak/3.8/NoToolsRepository.zip [32MB] and contains a few more (already unloaded) packages and fixes going back to the original 3.8 versions from SqF.org. Cheers, - Andreas

about MCConfigurations
by stéphane ducasse 26 Jul '05

26 Jul '05

Hi I wanted to see if I can load a complete configuration but I could not find how I can get a MC configuration. I opened the configuration browser but I could not figure where I could get a configuration or the latest stable configuration for example. Stef

How to republish in another repository?
by stéphane ducasse 21 Jul '05

21 Jul '05

Hi guys I started to load the latest versions and harvest some 3.9alpha pending items. Then I did a mistake that I forgot to change my logging information so when I published the changes theyr got published on my local repository but not on source.squeakfoundtiona..../39a I did not wanted to publish another version since I think that this would break the ancestor chain. Am I correct? I know that there is a way to publish an existing changes in another repository but I could not find where and how. Can you tell me how to do that (I did it in the past) but really I could not figure out how now. Stef

System Package: Versions in inbox
by Marcus Denker 13 Jul '05

13 Jul '05

Hi, When I tried to publish System-md.2.mcz, mc told me that there are newer versions. In the inbox, there is System-dvf.5, but this does not have System-dew.1.mcz as ancestor. So should that be ignored? Or merged? Marcus

Commited some simple fixes...
by Marcus Denker 12 Jul '05

12 Jul '05

Hi, Alex and I were looking into how to work with the new setup... so we commited two fixes from Lukas and a "isPrime" enh to Kernel: Name: Kernel-md.4 Author: md Time: 12 July 2005, 11:25:05 am UUID: d4ee1b12-f2b6-11d9-853d-000d933a223c Ancestors: Kernel-md.3 Change Set: TimespanEqualityFix Date: 18 April 2005 Author: Lukas Renggli Comparing a Timespan instance or one of its subclasses with an object from a different hierarchy raises an error. This changeset adds a check for the class in the beginning, all equality methods should have this anyway. After loading this changeset all tests of the chronology framework pass. Name: Kernel-md.3 Author: md Time: 12 July 2005, 11:19:03 am UUID: fcf3a2fd-f2b5-11d9-853d-000d933a223c Ancestors: Kernel-md.2 Change Set: CategorizerFix Date: 22 June 2005 Author: Lukas Renggli Fixes a very annoying problem where it is impossible to recategorize the system category list due to the default use of a limited print stream. All Squeak tools display an incompete printout of the categories what makes it impossible to edit and accept. To reproduce this bug create a few more class categories, open the standard browser and hit reorganize in the system category list. This changeset fixes the problem. Name: Kernel-md.2 Author: md Time: 12 July 2005, 10:57:44 am UUID: 02f6572e-f2b3-11d9-9516-000d933a223c Ancestors: Kernel-dew.1 0001287: [ENH] Integer primality testing Description SPINIELLI Enrico <enrico.spinielli(a)eurocontrol.int>: "please find attached a changeset which adds primality testing to Integer. (I wanted to solve Google puzzle {first 10-digit prime found in consecutive digits of e}.com so I needed a test for primality) I have implemented Algorithm P, probabilistic primality test, from Knuth, Donald E. 'The Art of Computer Programming', Vol 2, Third Edition, section 4.5.4, page 395" md/ab: we added a test for <= 1 that raises an error for now. (to be changed later... we'l ask him)

Squeak3.9a-6678.zip available
by Doug Way 10 Jul '05

10 Jul '05

Okay, I added two more updates and made the latest image available here: http://update.squeakfoundation.org/external/Squeak3.9a-6678.zip (The two updates are small if you have a 6676 image to update from.) 6677 flushes the MC caches, so that the saved image is much smaller again. 6678 adds a "master" repository for every package. For these four packages, I added what I thought were the master repository locations for each package. Please let me know if any of these are wrong: 'Monticello' - 'http://kilana.unibe.ch:8888/Monticello' 'MonticelloConfigurations' - 'http://source.impara.de/mc' 'SMLoader' - 'http://modules.squeakfoundation.org/People/gk/' 'SMBase' - 'http://modules.squeakfoundation.org/People/gk/' Then for all 31 other packages, the Submissions repository is added as the master repository for now. It's pretty cool to see both the 39a & the master repository for each package in the MC browser, you could easily merge versions back & forth if needed, etc. (I'm not sure if the Submissions repository is really a replacement for a master repository... maybe we should also add the Submissions repo added for the other 4 packages too, so it's on all of them. Was that the intent?) - Doug

[ANN] Monticello Package Browser v 0.5
by Alexandre Bergel 09 Jul '05

09 Jul '05

Hello, I finally found some time to work on the package browser. Screenshots and download are available on http://smallwiki.unibe.ch/monticellopackagebrowser/ Here is a small report for this version: What is new in this version: --------------------------- -A comment can be assigned to a package (of course, they are saved and retrieved), however the GUI is not well supported. -Running test unit classes (it is not related to packages, but this is quite useful). Tentative Roadmap: ----------------- 0.6 - GUI Prerequisite support for prerequisite packages 0.7 - Optimizations (Omnibrowser is a a bit slow, I need to dive into it) 0.8 - Support for package refactorings (fusion of two packages, fading a package into the system, divide a package into smaller pieces, ...) 0.9 - Binary support for packages. 1.0 - Squeak 4.0 Purpose of the project: ----------------------- Having one self contain package related tool -Packages are First class Entities, it make simpler operations such as renaming, refactoring (fusion of two packages), analysis, ... -Package related Information like class extension are quickly rendered. You can browse extension of the Package without waiting for dozen of seconds. Just to browse extension of the System package, about 40 seconds on my computer to find out that System extends Object, Behavior and ClassDescription with 5 methods. With the MonticelloPackageBrowser, it is instantaneous. -Packages are commented -Compatible with the PackageInfo naming convention (*mypackage-), therefore your project will be still loadable in a old image. -People who does not care about modules at all (e.g., if they prefer ChangeSets) will not notice any difference. -Load, save, repository management, get package information (e.g., class extensions) from within a single tool. Any feedback appreciated... Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.iam.unibe.ch/~bergel ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

How to cancel loading updates

Ok, I've added the fresh new packages to the 39a project. I renamed the old #Squeak3.9alpha stream in updates.list to #Squeak3.9alphaold, and started up a new #Squeak3.9alpha stream, and started adding updates. I decided I should at least put up a warning dialog for people who have existing 3.9alpha images following the old stream (which diverged considerably from 3.8), telling them that they probably need to start over. I added this update as 6670, the first update in the new 3.9alpha stream. (I then added the Reorg as 6671.) One problem is that the warning offers to stop the updates for those people (which is the sensible thing for them to do). But I couldn't find a good way to bail out of the current updates process without proceeding to the next update. Is there a good way to do this? Terminating & restarting the current UI process would be acceptable... the exact equivalent of typing cmd-. and closing the pre-debug window. Is there a good DoIt for this? (This is not something we'd normally do... but in this case I just want to tell people gracefully that their image is at a dead-end and not force them to continue updating, which will almost surely break things.) You can try updating from an old 3.9alpha image to see this in action. (Another alternative is to abandon the 3.9alpha stream and start the new one with a new name, such as 3.10alpha, or 4.0alpha. (Like we did with 3.3alpha.) Then this particular problem goes away. But that seems like an extreme measure, there isn't really much in the old 3.9alpha, I'd rather just start it over.) Anyway, while waiting for feedback on this, I'll go ahead and finish up the rest of the updates including the MCConfiguration update, so that we have an official 3.9a partitioned image to work with. - Doug
