Re: [Pharo-project] [squeak-dev] Squeak/Pharo/Cuis on Android

by StÃ©phane Ducasse

I would be interested in any attempts to produce native bytecode on java vm for pharo. Now this is the usual equation: money and money or time. JSqueak or Potatos squeak could be also interesting.

by laurent laffont

Hi, is it possible today to distribute Pharo apps through Apple App Store (OSX) ? If no, why ? Can I hope it will be possible or should I learn objective-C ? Laurent

[Pharo-project] [ANN] ESUG supports once again SqueakDBX

by Mariano Martinez Peck

We are really happy to announce that ESUG will sponsor us once again through the ESUG Summer Talk project. This means that we have reached the ESUG expectations and that they still think that relational database access is an important matter in Smalltalk. One important thing is that we are going to rename the project (we are still working on it) since SqueakDBX runs not only in Squeak but also in Pharo, and there have been even ports to Dolphin. What's the reason for this decision? Because we do not want to couple ourselves to a smalltalk dialect nor to OpenDBX, because our project is much more than that (later I will tell you about our plans). So, these are some of the possible names: ObjectPark, SmallParking, Parktalk, SmallValet, Valetalk, ValetST, NorayTalk, Ballard, Noray and Cruise. Please let us know which one is your favourite or help us find a new one. Another important subject is the team. There will be three "mentors", Esteban Lorenzano, Diogenes Moreira and myself, Mariano Martinez Peck; and three students: Guillermo Polito, Nicolas Scarcella and Santiago Bragagnolo. We are open to suggestions and ideas. In addition, we have defined a possible list of actions that I copy at the end of the email. For the moment, the url remains www.squeakdbx.org and the mailing list squeakdbx(a)lists.squeakfoundation.org Once again, we want to thank ESUG for their support and trust. Thank you very much, SqueakDBX team Possible list of actions: 1) Change SqueakDBXâs name. 2) Update GLORP version since the actual one is 3 years old. Port it again from VisualWorks, create a VW porting tool (may be). Complete support to Glorp. Today it works with PostgreSQL, Oracle and MySQL. Make it work with most databases OpenDBX supports. 3) Create a lightweight solution, alternatively to GLORP. There are some options: Make SqueakSave work with SqueakDBX. SqueakSave developers already contacted us because they wanted to do it. SqueakSave seems to be 20% slower than Glorp but you don't need to write the mappings :) Adapt Ramon Leon's active record to use an abstract database driver, and create a driver for SqueakDBX. Port the new Glorpâs kind of active record to Pharo. (included in 2). 4) Write a Pharo By Example 2 chapter based on the card game Stef built ;). 5) Cog compatibility. 6) Use Alien instead of FFI. Eliot is working on a threaded CogVM. One of the projects of the GSoC of this year was to make something similar to a threaded FFI. What the student did is a modification in Alien (I think) that can be run in a multithreaded envirorment. He worked with Eliot. The idea is when Eliot releases the threaded CogVM, this FFI would work our of the box, and would avoid locking the WHOLE vm while a C function is being invoked (as it happens today with FFI).....So....when that VM is released, we MUST migrate to that). 7) Explore performance issues (maybe with our approach of "In thread execution plugin"). 8) Complete integration with OpenDBX. For example, Oracle, for large objects (Clob, Blob, etc) use specific functions. There are specific functions in OpenDBX that have to be used if the database uses specific functions (oracle is the only one for the moment.). We don't manage those functions yet. 9) In this link http://www.squeakdbx.org/Targets%20and%20Features You can see a list of future possible features like Connection pooling (now it is done!), Prepared statement interface, Store procedures, Escape and avoid of SQL insertion, Authentication support: extends to other methods, not only user/password, Full text support, etc.

[Pharo-project] Issue 3781 in pharo: Finder version 30 does not report all selectors - 2 problems

by pharo＠googlecode.com

Status: New Owner: ---- New issue 3781 by DougEdmu...(a)gmail.com: Finder version 30 does not report all selectors - 2 problems http://code.google.com/p/pharo/issues/detail?id=3781 Package Finder-BenjaminVanRyseghem.30.mcz Two problems with the Finder UI. Problem 1: Using Selectors mode, if a class has the same method name for instances and classes, Finder only lists the class entry. Example: the HelpBrowser class has both an instance and class method for 'open'. Instance method: open "Open the receivers window" self refresh. window openInWorld. and class method: open ^self openOn: SystemHelp Using Finder tool, type in 'open' in the box (set mode to Selectors). Notice that only "HelpBrowser class" appears in the list. The "instance" method (which would show up as HelpBrowser without the word "class" after it) does not appear on the list. Problem 2. Same example, change mode from Selectors to Classes, and type "HelpBrowser" in the box. Notice now that only the instance method for 'open' appears. The class method "open" does not appear.

[Pharo-project] GemSource downtime tonight 9pm PST to 11pm PST

by Dale Henrichs

The server for http://seaside.gemstone.com/ss is being moved to the VMWare corporate data center tonight and the old site will be shut down at 9pm. We expect it to take a couple of hours for the new DNS to propagate so the new site will be available at 11pm. Aaron will be monitoring the gemstone beta list at: http://seaside.gemstone.com/mailman/listinfo/beta Feel free to post any questions or problems to that list and Aaron will respond. Folks using Metacello, shouldn't notice a problem because an alternate Metacello repository is maintained at: http://www.squeaksource.com/metacello.html and the Metacello loader should automatically switch to the repository if GemSource isn't available.
