Re: [Pharo-project] [smalltalk-research] [Survey] Assess the cycles in your software

Hi Lukas, The question should be: How many packages are contained in the software you want to analyze ? I change it and commit a new version. Thank you Lukas.

[Pharo-project] Fwd: [Vm-dev] [ANN] SqueakSSL - a platform interface for SSL/TLS
by Geoffroy Couprie July 19, 2010

July 19, 2010

Here are some great news :) ---------- Forwarded message ---------- From: Andreas Raab <andreas.raab(a)gmx.de> Date: Mon, Jul 19, 2010 at 8:13 AM Subject: [Vm-dev] [ANN] SqueakSSL - a platform interface for SSL/TLS To: The general-purpose Squeak developers list < squeak-dev(a)lists.squeakfoundation.org>, Squeak Virtual Machine Development Discussion <vm-dev(a)lists.squeakfoundation.org> Folks - Since the weekend is over I've decided to release what I got so far and consequently I'm happy to announce the availability of a new interface to the platform SSL/TLS facilities for Squeak. SqueakSSL is a plugin-based approach which utilizes the platform implementation; currently the SCHANNEL SSPI on Windows and OpenSSL on Unix. To use SqueakSSL you need the following pieces: 1) The plugin for your platform. For Windows, you can download the plugin from http://squeakvm.org/win32/release/SqueakSSL.zip For Unix you'll have to compile your own; I'm attaching the relevant part of the platforms tree. Mac support is currently not provided but the OpenSSL based version can probably be adapted for Macs. 2) The SqueakSSL source code and tests. All of this can be found at http://www.squeaksource.com/SqueakSSL.html You need SqueakSSL-Core for the code and SqueakSSL-Tests for the unit tests (SqueakSSL-Plugin is the plugin source which you don't need and which we'll probably push into VMMaker). Once you've downloaded and installed everything correctly, you should be able to try SqueakSSL via the google example, which makes a query to encrypted.google.com: SqueakSSL google: 'Squeak'. If the query fails your plugin is probably not installed correctly (it seems unlikely that Google's cert has an issue :-) 3) For further tests (incl. the unit tests) you will need to provide a server certificate that can be used by SqueakSSL. On Unix you can do that using the openssl command line tools and once you've generated your cert, you can tell SqueakSSLTest to use the cert. On Windows the process is a bit more involved - you need to have a valid cert AND have it installed in the local certificate store (a description can be found at http://support.microsoft.com/kb/816794 but make sure you install it in your *user* account not the computer account). Once you have the cert installed, you can run the unit tests which should now succeed. Obviously, this is an early release and there's plenty of work that remains to be done, so help is welcome. However, it is starting to become useful and consequently I'm intending to update WebServer and WebClient soon for HTTPS support. Cheers, - Andreas

[Pharo-project] selection in OB browser
by StÃ©phane Ducasse July 18, 2010

July 18, 2010

Hi lukas I refactored a lot of code with gary yesterday and when we used refactor like push up method for example, we got bitten by two problems after the method is moved, the method with the same name but self halt is selected. I think that it would be better to select another one, like that we can directly refactor the next one. Else you read again the code during 2 s and think ok this is the old one but this is really taking cycle of attention. The selection is strange, often I got an item kind of selected because it was in light blue but the list itself was not selected so I could select the refactoring to happy but the system barked telling me that the selection was not good and I have to click again on the item so select it for real (in the case I could see the selection because the list was surrounded by a blue line). If you have time this would be great to fix these two problems. Stef

[Pharo-project] Cleaning morphic?
by Guillermo Polito July 16, 2010

July 16, 2010

I know morphic is one of the greatest issues Squeak and Pharo have. And I'm tired of the kilometric morph hierarchies with tons of methods that noone uses, and the impossible traceability of the morphic code... And I'm sure that a lot of people tried it before... And this isn't the highest priority. But I think morphic cleansing should be done. So, while i'm now in bed beacause of a flu, hehe, I want at least remove unused morph classes and unused methods... Or maybe we can separate some things from the core. Of course I will be "spamming" in the list asking for the changes I will do :P. what do you think? Do I open a ticket? Guille

[Pharo-project] VM more flexible for research?
by Mariano Martinez Peck July 15, 2010

July 15, 2010

Hi folks. I am a newbie for both research and VM. However, in the little time I have been working on this, I always need some extra bits in the object header to do some experiments. And the problem is that I always have only one :( So I come to the idea of having a more flexible VM for the people that want to experiment with it. The first idea was to remove compact classes. But of course, there may be much more ideas or things to do. What do you think? Cheers Mariano

[Pharo-project] Evaluation of Pharo for Commercial Project
by Torsten Bergmann July 15, 2010

July 15, 2010

>We are used to VisualAge and VisualWorks, which clearly shows the >structure of packages in the browser Do you know O2 browser for Pharo? It's an additional browser that shows the packages similar to VW. See [1] and ask on the pharo list to get the right version for your image. >We are uncertain how packages are made and how they show up in Monticello. Monticello is simple - an MCZ is just a ZIP including the code. Monticello (ab)uses class/method categories to find out which package the code belongs to. Packaging is simple: in short if you create a package "MyApp" in Monticello any class that is in a class category that starts with "MyApp" will be in this package. Example: a) class "MyClass" in class category "MyApp-Core" and b) class "MyModelClass" in class category "MyApp-Core-Model" and c) class "MyTestCase" in class category "MyApp-Tests" 1. When you create a Monticello package (in the Monticello browser) called "MyApp" automatically all three classes (core and tests) are then into this simple package (click on "Browse" to verify) 2. If you want core and tests in separate packages you create two packages "MyApp-Core" (automatically including a and b) and "MyApp-Tests" with c. Method extensions: If you put a method in a category with a leading star and your package name it gets included too. So if you put a method #foo on String into the method category "*myapp-core" it is a method extension on String packaged in "MyApp-Core" package. If you have well named packages this works good and even works in the large. Typically packages are stored in repositories (www.squeaksource.com repo server, local (shared) directories, FTP, ...) Read the http://pharobyexample.org/ book to get more info on Monticello. Also check out http://pharocasts.blogspot.com/ > Since we are unable to organize our code in packages, controlling and > verifying dependencies between them is hard. This is adressed using METACELLO (which manages Monticello packages) - think of Monticello to provide packages and Metacello as configurations to manage which package (version) depends on which other package (version) You just describe baselines (structure and dependencies) and versions that fit together in a class/package called "ConfigurationOfMyApp". See [2] and [3] and the ProfStef teacher workspace that comes with Pharo to learn more. If stuck just ask. Namespace support and better Breakpoint support will (hopefully) adressed in the near future. Also better packaging. Bye T.

[Pharo-project] material for thought

July 15, 2010

Lessons learned by the seaside lead! from http://blog.fitzell.ca/2010/07/seaside-3-release-candidate.html â¢ When your wonderful, dedicated users start putting your code into production, they're telling you it's ready to be released. Listen to them. â¢ We don't have the manpower to carry out the kind of QA process that goes along with an Development, Alpha, Beta, RC, Final release process. â¢ We need to figure out how to get more users actively involved in the project. This could be by writing code but probably more importantly by writing documentation, improving usability, building releases, managing the website, doing graphical design, or something else entirely. The small core team simply can't handle it all. I think that the point three concern .... you :) If you want really pharo to be a success you should from time to time step back from your keyboard and think about the little actions that you can do to make pharo better and we all can do something.

After i port my code and do some work for seaside 3.0 integration. Now when i test the application ( WAKom startOn: 8080 ) the MAC report a CPU load of 5% + 3 %. After some work : ( web request to my application - other web request - Pharo source change - other Mac application ( word -excel ), but only if Pharo image is load, the CPU load go to: CPU User 35 % CPU system 40% . For now i don' understand because this load. When i close the application ( Pharo - Safari - ....) the load of CPU don't change ( 35% + 40% ). For solve it i need to restart the Mac.

[Pharo-project] Ryerson University, Toronto
by Chris Cunnington July 13, 2010

July 13, 2010

Last night was a meeting of the Toronto Smalltalk Users Group. It was made clear to me that our host for the meetings (who wasn't there, because we meet on a patio in summer) at Ryerson University, Dr. Joshua Panar had chosen Pharo to introduce to his second year programming students. http://www.scs.ryerson.ca/~jpanar/ I pushed for Squeak and run over by Bob and Yanni. This is foul perfidy on their part of which they have not heard the last. It seems to me that a lot could be accomplished if somebody from the Pharo executive could send Josh some sort of email of introduction. He is in a position to do a lot for Pharo, and a single email from somebody on your side would doubtlessly energize him a great deal. I think he'd find that very encouraging. He's a very nice guy.

ConfigurationOfGrease - 1.0-alpha9.3 ConfigurationOfSeaside30 - 3.0.0-alpha5.15 ConfigurationOfMagritte2 - 2.0.5 ConfigurationOfPier2 - 2.0.6 ConfigurationOfPierAddOns2 - 2.0.6 ConfigurationOfSeaside - 1.0.5 The configurations are available in http://www.squeaksource.com/MetacelloRepository. Note that the mcz files in the Seaside3.0 config predates the mcz files in 3.0 RC that was recently announced, so I apologize for the potential confusion. We are shipping GemStone/S 64 2.4.4.1 very soon now and I needed to coordinate the releases of Seaside3.0/Magritte2/Pier2 that are available on GemStone. The announcement of 3.0 RC came too late to incorporate into our release cycle. I'll be pushing out updated configs shortly. The big change with this release is that there is a new 'Base' group defined that loads the minimal packages for running Seaside (i.e., no development packages, no examples, no java script. etc.) thus making it possible to perform a load into a production image of only the packages/features you want. The new versions of the Magritte2, Pier2 and PierAddOns2 are structured to load only what is absolutely needed for each of those projects, again making it possible to load Pier2 into an image without having the entire Seaside3.0 development come along. One of the upshots of loading only the minimum required is that you will need to choose an adaptor to explicitly load (Kom or Swazoo for Pharo/Squeak folks). So if you want to load a minimal Pier2 and use the Kom adaptor, you will evaluate an expression like the following (after loading the Seaside3.0 and Pier2 configurations: (ConfigurationOfPier2 project version: '2.0.6') load. (ConfigurationOfSeaside30 project version: '3.0.0-alpha5.15') load: #( 'Seaside-Adaptors-Comanche' ). If you want to add the Seaside3.0 development environment to your image, you would evaluate the following: (ConfigurationOfSeaside30 project version: '3.0.0-alpha5.15') load: #( 'Development' ). and if you wanted the development environment plus tests you'd evaluate the following: (ConfigurationOfSeaside30 project version: '3.0.0-alpha5.15') load: #( 'Development Tests' ). As for the ConfigurationOfSeaside, I have decided that the 'Seaside 3.0' target will load the full Seaside3.0 code base. However, I have added a 'Seaside 3.0 Production' target that loads the minimal Seaside packages plus both adaptors. I have updated the #workspace method with additional examples. For the GemStone users out there keep your eyes peeled for the announcement of GemStone/S 64 2.4.4.1 where I will provide additional (mostly) GemStone-specific information. Well with as many moving pieces involved in this announcement I expect that there will be a stitch or two dropped (which reminds me that you ought to make sure you are using the latest version of Metacello when loaded Seaside3.0) so feel free to drop me a line with comments/problems and I will see if I can address them. Now that GemStone has caught up with Pharo and Squeak (very soon, I promise:) I don't anticipate making these multi-config coordinated releases any time soon... Putting together a Seaside 3.0 RC config is next up on the list... Dale

[Pharo-project] Tracing on Linux
by Schwab,Wilhelm K July 13, 2010

July 13, 2010

I am trying to track down a segmentation fault in calling into the Gnu Scientific Library. These are things that I had working under Windows+Dolphin and am now trying to do with Pharo and Linux. Offsets to structure elements and sizes of structures are possible snags, but the calls that are failing should be reasonably independent of such things: I call the relevant allocation method and pass along the pointer, so even if my interpretation of the structs is bogus, I would still expect the functions to succeed. That is all the more true of new functions that I am adding for testing purposes. The GSL functionality is split into two libraries, and the .so modules appear to be hobbled on Linux due to circular dependencies between them. A wrapper .so that is linked to both libraries seems to allow me to call "all" of the functions (the few I have tried to access) and gives a home for code of my own. I went so far as to compile some GSL sample code, and it does not crash. I further linked it to my wrapper library and it still works calling the GSL functions through the wrapper (or at least I *think* that's happening). I plan to gradually sneak up on the crash by moving things into my library and then hopefully into Pharo via FFI. On Windows, I would use OutputDebugString() to write tracing messages to look at what is happening until I found the problem. How do you unix VM gurus tackle such debugging problems? Bill

[Pharo-project] Sequential Dictionary
by Joel Turnbull July 13, 2010

July 13, 2010

What is the group's recommendation for creating a sequential Dictionary? i.e. A Dictionary who's associations are ordered. Is there any precedent for this? Or does it sound like I'm barking up the wrong tree? In my model, I've subclassed Dictionary into QuantityDictionary to store line items, where the key is the item and the value is the quantity of the item. It validates that the value is always a numeric, removes the association when the value goes below zero, and other stuff specific to my application. Now I'm finding it makes sense to be able to order these associations. Imagine a recipe ingredient list, where you add and edit quantities of ingredients, and you want to put the ingredients that you use earliest in the recipe at the top of the ingredient list. Before I put any more work into it, I just wanted to make sure that a sequential dictionary makes sense, and get your ideas on how to generally go about implementing that? Thanks.

[Pharo-project] iPhone Cog Stack VM, performance numbers
by John McIntosh July 12, 2010

July 12, 2010

As always it's difficult to determine how best to benchmark. So given: | savedMorphs | savedMorphs := World submorphs. World removeAllMorphs. self halt. ^ [[10 timesRepeat: [Browser fullOnClass: Object selector: #yourself]. World submorphs do: [:m | m delete. self currentWorld doOneCycle]] ensure: [World addAllMorphs: savedMorphs]] timeToRun inspect I can say that the Cog Stack VM on the iPhone produces numbers like 48.081 seconds 47.858 seconds The original VM did: 74.415 seconds 74.257 seconds making the iPhone COG VM 1.55x faster A 2.33ghz mac book pro mac vm 5.7b1 does it in about 8.3 seconds with a COG JIT VM 5.8 that takes 2.6 seconds or about 3.2 faster -- =========================================================================== John M.

Hi we would like to have display several time the same piece of code (here 'find') into a piece of text (here in method testCycle). In the following method we would like to have all the find occurrences selected. Does anybody have a pointer? Stef and Simon testCycle | a b c | MOGraphFixture cycleGraph: dom. dom run. dom nodes do: [:n| n model = $c ifTrue: [self assert: n isDominant. self deny: n isDominated] ifFalse: [ self deny: n isDominant. n model = $d ifTrue: [self deny: n isDominated] ifFalse: [self assert: n isDominated] ] ]. a := dom findNode: $a. b := dom findNode: $b. c := dom findNode: $c. self assert: (a find = c). self assert: (b find = c).

I guess it can be interested for you also. ESUG will be happy if you help to do some buzz about the conference. Forwarding emails to other mailing lists, post in your blogs, twitter, facebook, etc, always help. It would be great to expand the community and forward this email to other communities like ruby, python, linux, etc.... For more details: http://www.esug.org/Conferences/2010 Cheers Mariano ---------- Forwarded message ---------- From: stephane ducasse <stephane.ducasse(a)free.fr> Date: Mon, Jul 12, 2010 at 10:40 AM Subject: [Seaside] Looking for smart and good programmers? Attend the premium conference on Smalltalk! To: Seaside - general discussion <seaside(a)lists.squeakfoundation.org> We are all looking for smart and good people... Now the best to get in touch with them is to go where they go and have a nice beer with them. Did you think about coming to ESUG the key world conference on Smalltalk to meet talented people? Did you think about sponsoring ESUG so that programmers get aware of your business? Regularly we pass job interview at ESUG. Why not you? Each year ESUG offers the possibility to young guys to participate to ESUG as student volunteers you can also come and talk to them. Some data: Amsterdam 170 participants Brest 154 Barcelona The dead-line for registration at early bird fees is approaching (one month to go). So, hurry up and register on our new seaside-based server. http://registration.esug.org/ This server comes with new features. You can now do a group registration and make a single payment. Also, we have reduction tickets (typically for Golden and Platinum sponsors). The ESUG 2010 conference program is about to be ready, and it is as promising as was for the previous editions of the conference. Checkout the preliminary schedule is already on the web, http://www.esug.org/Conferences/2010 See you in Barcelona, ESUG board. _______________________________________________ seaside mailing list seaside(a)lists.squeakfoundation.org http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside

Apparently we lost some classes.... probably trying to changes packages with MC.... bad bad bad idea. We lost MczInstaller for example. ;) Bad bad bad. We will not change package structure before fixing MC else we are doomed to lose classes. Stef

[Pharo-project] OB contextual menu item 'method containing' broken: is it useful?
by Simon Denier July 10, 2010

July 10, 2010

In 1.1 RC4 (and before), when opening the contextual menu in the source pane, there is an option for 'method containing' among the search actions. It's not clear what is is supposed to do. Is it the OB implementation of the 'method strings with it' action, which is also available? Anyway, it is broken as it raises a DNU #allMethodsNoDoitsSelect: -- Simon
