[ANN] Magma release 41
by Chris Muller 14 Oct '08

14 Oct '08

I am pleased to announce release 41 of the "Magma" object-oriented database management system has been posted to SqueakMap. Release 41 brings significant improvements in performance, scalability and robustness, particularly on slow networks, as well as improved transparency and operation. Improved Performance and Scalability At the core of the better performance and scalability are architectural improvements to the networking module, "Ma Client Server", which now maintains up to 50 simultaneous socket connections instead of just one, and now also compresses request/response ByteArray's when appropriate. The compression, alone, showed more than 100% performance improvement on ADSL-speed network connections. Thanks to ofset.org for funding this development. Improved Operational Monitoring An all-new performance and system-health monitoring package called "Ma Statistics" was developed and integrated into all layers of the Magma architecture. Performance statistics for the last half-hour (hour, day, week, your choice) are captured in five-minute (also adjustable) intervals. Is the server taxed or loafing? What was the average response time for clients? What was the longest response-time for any single request for any client? What was the average size of each response? These and dozens of other statistics are now captured while the server runs, with no performance penalty. Improved Distribution A MagmaForwardingProxy is a "bookmark" to an object in another repository, further improving performance, scale, distribution and database administration. These have been present for some time, but have been heavily tested and improved in this release. Improved Transparency Transactions may now be as long as desired. In fact, transactions may even span image saves! You may start an image, connect to a Magma repository, begin a transaction, make some changes, save and exit the image (not yet having committed), reboot the image later (objects in the image are brought up to date with changes by other sessions), continue any further changes, and finally commit successfully. Improved Operation With remote administration, release 41 better supports headless-operation mode. The server now also keeps track of its memory consumption relative to capacity and will take action to reduce memory utilization, as necessary, before it becomes a problem (although Magma servers have always operated with a relatively low and fixed memory footprint, albeit dependent on number of clients and activity).

[ANN][Squeak-dev Images] October 2008 versions
by Damien Cassou 13 Oct '08

13 Oct '08

Hi, I've just uploaded new squeak-dev and squeak-web images based on Squeak3.9.1-7075, Squeak3.10.2-7179 and Pharo0.1-10082. More information and download: http://damien.cassou.free.fr/squeak-dev.html Pharo-based images can be downloaded at: http://code.google.com/p/pharo/wiki/Downloads?tm=2 Download statistics at http://damiencassou.dabbledb.com/publish/dev-imagesdownloads Changes in this version: --------------------------- - Pharo images are based on version 10082. - UIEnhancements has been renamed to Polymorph - NiceFonts is temporarily not included - ShoutWorkspace is now the only supported workspace. If you don't want color highlighting, open the workspace menu and uncheck the option (this is a new feature provided by Andrew Tween). - David Röthlisberger improved OmniBrowser a lot. Here is his comment: - Integrated tree in package column for a better navigation of packages and their class categories - Added support to place packages at the top of the list - Merged TraitsIntegration into OB-Enhancements - Merged OmniBrowserFixes into OB-Enhancements - Improved and enhanced icons for methods and classes: * Class icons used to denote type of class (eg. exception or collection classes). User can implement #browserIcon to specify icons for application classes. * Method icons to reflect structure or content of methods, eg. inheritance structure (abstract methods, methods with super- or sub-implementations, etc.), super sends, halts or flags used in a method, exceptions raised, etc. * Mouse-over support for icons to get an explaining label for the used icon * Icons are clickable: Clicking on an icon denoting super send or super-impl. brings you to the method in the superclass, similar for methods with sub-implementations. - Various problems fixed I was not able to generate a pharo-web this month, sorry.

I hope that will be fixed soon for a reintegration. - Algernon is included in all images now (Shift+enter to launch it) and is linked to OB (thanks to OB-Algernon) - Like every month, David Röthlisberger fixed a lot of issues in OB-Enhancement - Refactorings now have the possibility to rerun rules (thanks to Lukas Renggli) - OB-Tools has been temporarily removed. I would like to put it back as soon as possible because I think these tools are much better and extensible than what exists currently. Please help Lukas and implement the few missing features (like http://bugs.squeak.org/view.php?id=7164 and http://bugs.squeak.org/view.php?id=7148) I tried to integrate UI-Enhancements in all images but it failed.

OutputDebugString() or equivalent?
by Bill Schwab 11 Oct '08

11 Oct '08

I am still struggling with a service that either will start and immediately stop, or will run but appears unable to listen on port 8080. Usually with things like this, I simply litter code with some type of tracing (often OutputDebugString() calls on Windows), and try to bracket the problem. This seems like a good candidate for it, because attaching a debugger to Squeak (particuarly for the case in which it won't stay running) sounds like a LOT more trouble than printing "got this far" messages until I know where it quits. -log: has not been much help. Is there something similar to the change or error logs that might be appropriate to use? Bill Wilhelm K.

Help with font rendering
by Andreas Raab 11 Oct '08

11 Oct '08

Folks - We (Qwaq) are looking at integrating native font rendering on Windows and Mac in our clients. The main reason for this is that one of the major differences in look is using "non-standard" fonts (all of the currently available technologies -incl. freetype- have that property). If you know the Squeak font subsystem and native rendering on Windows and/or Mac and are available for some consulting drop me a note off-line. We are looking for a short to medium term engagement in this area. Cheers, - Andreas

porting Squeak ... Java
by Mark Volkmann 11 Oct '08

11 Oct '08

I see there was a project named Talks2 that attempted to port Smalltalk (maybe not Squeak) to the Java Virtual Machine (JVM). Does anyone know if that project is still active? Is there a web site that describes what is involved in creating new ports? I understand most of Squeak is implemented in Smalltalk and that only a small core needs to be ported in order for it to run on new platforms. Beyond getting Squeak to run on the JVM, another goal might be to enable generation Java bytecode from Smalltalk classes. That would make it possible to implement libraries using Smalltalk syntax that can be used by Java developers. Another would be to come up with a way to wrap Java libraries so they can be easily invoked from Smalltalk code. Do these seem like unreasonable goals? --- Mark Volkmann

iphone vm 1.06b2 goes out
by John M McIntosh 11 Oct '08

11 Oct '08

I've pushed out a 1.06b2 VM, this fixes a problem I saw where select() was returning garbage as an error code. Turns out we were calling select() with a zero max fd. Normally we don't do that, but during testing a change to aioSleep() aggravated the issue. Users should not notice a different, but should download the latest VM. -- = = = ======================================================================== John M.

Re: Squeak/Pharo as service on Windows

Andreas, Thanks, that gives me some things to check. Bill ===================================== Andreas Raab <andreas.raab@...>andreas.raab@...

However, I am still curious about what might be > going wrong and how to find it. I don't know svrany so you'll have to ask someone more knowledgeable. However, I can give you some general advice: Most importantly, try the *EXACT* command line you are using from an obscure location and see if that works as you expect it. You might be relying on some implicit assumption that do not hold true when running as a service. For example, if you are making assumptions about the startup directory either by wanting Squeak to find an image implicitly or by using a relative path you could be badly off. Also, access to the directory might be an issue (I don't know if srvany allows you to specify which user to run as). Lastly, you should try to generate a log file (using -log:) and check that or the event viewer to see if srvany has anything to say about startup. Hope this helps, - Andreas Wilhelm K.
