r42Alpha3
by Chris Muller 24 Dec '08

24 Dec '08

I have been performing stress-testing on Magma for the last few days which has resulted in several fixes, performance upgrade, and functional improvements worthy to call "r42Alpha3". I am getting really pleased with Magma r42 now because it behaving very much like a "industrial machine" during stress testing. Running 14 separate client "stressors", with server CPU at 100%, now maintains consistent memory utilization and performance, even after more than one-million elements added to a MagmaCollection in the test. This latest configuration is now posted to the "MagmaTester" project of squeaksource. - Chris

[ANN] Magma release 41.2
by Chris Muller 19 Dec '08

19 Dec '08

I have just posted another minor maintenance release for Magma 41 called "41.2" to SqueakMap and the "Magma" project of squeaksource.com. Release notes: - Some low-level optimizations to maUint:at: resulting in better performance. - Now running MaTimers at userInterruptPriority-1 instead of userInterruptPriority+1. Afterall, they're only producing application data, so let's not supercede the real need for userInterruptPriority processes. - Improved support for subclasses of Dictionary and Set. - Fixed performance regression; don't #abort when server #refreshView; it is only necessary to #refresh, it will improve significantly server latency when a lot of commits are being performed. - Chris

Commit an existing MagmaCollection with index
by Hilaire Fernandes 19 Dec '08

19 Dec '08

I don't remember about that: Is it fine -- regarding the index -- to first populate a MagmaCollection with indexed elements, then commit the MagmaCollection in the database? I am tempted to think yes. Hilaire

Magma + FreeType font
by Hilaire Fernandes 07 Dec '08

07 Dec '08

I am now using Pharo with FreeType fonts + Magmar41.1. The font I am using use the LogicalFont class (this is how I declare in my code the TT font I am using). I have extended LogicalFont to get it persisted: First with a new way to instantiate it: LogicalFont class>>familyName: familyName pointSize: pointSize emphasis: code ^ (self familyName: pointSize pointSize: pointSize) emphasis: code; yourself Then three methods for persistence, I copied the existing TType class persistence methods: maAsStorageObject "I am about to be written on an object file. Write a reference to a known FontSet in the other system instead." "a path to me" ^ DiskProxy global: #LogicalFont selector: #familyName:pointSize:emphasis: args: { (self familyName). (self pointSize). (self emphasis) } maUsesStandardStorage ^ false maWantsPreSerialization ^ true Basically these methods are used when I am persisting in the Magma Database a morph with some text. Now when I am fetching such Morph from the Magma data base in another image (with the same code extension) I got a Segmentation fault (the trace is included there). The crash is clearly happening in FreeType code, in the primitive called from FT2Face>setPixelWidth:height: Probably I got something wrong in my persistence code, I will be more than happy with any kind of tips.

[ANN] Magma release 41.1
by Chris Muller 01 Dec '08

01 Dec '08

I have just posted release 41.1 of Magma to both squeakmap and the "Magma" project of squeaksource. There is no new functionality, but 41.1 contains some important factorings and improvements in preparation for release 42. There are also some important fixes to a couple of unfortunate bugs that crept into release 41. I recommend anyone using 41 to upgrade to 41.1. - Chris
