Magma 1.5 for Squeak 5 ships!

magma1.5

From Chris Muller:

I am pleased to announce version 1.5 of Magma for Squeak 5, now available on SqueakMap.  Magma allows multiple Squeak images to collaborate on a single, large object model, with the robustness and control expected from a database.  It offers the most transparent db access possible for Smalltalk, affording the user the ability to develop complex, performant designs, iteratively, on-the-fly.

It has been designed for “continuous flow” development, the way Smalltalkers like and expect to work.  For example, I could have connections open to 3 separate databases, open transactions in any of them, and having restructured a class hierarchy in the model, and stepping through the debugger when that “final boarding call” for my flight is announced.

Thanks to the image, this scenario has never been a problem for Smalltalkers and Magma is deliberate to ensure this flow is maintained.  Once at 10K feet, I can resume stepping through that same debugger within 5 seconds of restarting the image, DB connections intact, commit my transactions when I’m ready, done.  Magma handles every aspect of that use-case correctly even in multi-user environments, and has so many safety and integrity features, it is the safest way to develop and keep a model in Squeak.

This release coincides with the release of Squeak 5, and has many improvements and fixes over Magma 1.4.  Detailed notes about these improvements are available at http://wiki.squeak.org/squeak/6209.

– Chris

The Weekly Squeak

Squeak 5 is out!

squeak5.0

From: Chris Muller,

In the 17 months since Squeak 4.5 was released, a huge development effort took place to create the next generation virtual-machine for the Squeak / Pharo / Newspeak family of programming systems.  Squeak is the modern incarnation of the Smalltalk-80 programming environment originally developed at the Xerox PARC.

Bert VM Icon

“Squeak 5” introduces this new VM and associated new memory model, collectively referred to as “Spur”.  Presented [1] by Eliot Miranda and Clément Béra at the 2015 International Symposium on Memory Management, this new VM affords Squeak applications a significant boost in performance and memory management.  Among other optimizations, the #become operation no longer requires a memory scan.

Object pinning and ephemerons are also now supported.  The release notes [2] provide more details.

spur_gear

The new memory model requires a new image file format.  Although this new format results in about a 15% increased memory requirement for the same number of 4.x objects, a new segmented heap allows memory to be given back to the OS when its no longer needed, a great benefit for application servers.

As forward compatibility is as important to the Squeak community as backward compatibility, Squeak 5 is delivers an image with identical content as the recent 4.6 release.  Although this new Squeak 5 VM cannot open images saved under the prior 4.x Cog format, objects and code can be easily exported from the 4.x image and then imported into Squeak 5.  Applications whose code runs strictly above the Smalltalk meta layer will prove remarkably compatible with the new format, most applications will require no changes whatsotever.

Squeak 5 is the result of monumental effort by a tiny group of very talented people, but its also just the beginning of yet a new effort; Spur is just a stepping stone to a more ambitious goals planned over the next five years.

Twilio-smalltalk for Pharo

I already posted about a Tropo binding for Pharo to work with phones and SMS.

Now there is another option available: a Smalltalk library for communicating with the Twilio REST API (http://twilio.com). The project is hosted on GitHub.
