[Pharo-project] XML packages, CDATA and encoding
by Torsten Bergmann Jan. 16, 2011

Jan. 16, 2011

Create a file "test.xml" with the following contents (german umlaut): <?xml version="1.0" encoding="iso-8859-1"?> <test><![CDATA[ZaunkÃ¶nig]]></test> After loading ConfigurationOfXML try to parse it: |fs| fs := FileStream fileNamed: 'test.xml'. XMLDOMParser parseDocumentFrom: fs. => gives an error: 'Invalid utf8 input detected' => it works if you remove the CDATA section Looks like UTF8TextConverter is used independent from the encoding of the XML...

[Pharo-project] new Cog VMs
by Eliot Miranda Jan. 15, 2011

Jan. 15, 2011

Hi All, I've released a new version of Cog that has a substantially improved code generator along the lines of Peter Deutsch's HPS (VisualWorks) and various of Ian Piumarta's VMs. These all use a simple tecnique to identify constant references in bytecode and to support a register-based calling convention. While this does produce faster code it tends to accelerate low-level code much more than high-level code as you can see by the following benchmarks: SimpleStackBasedCogit: [1 to: 100000000 do: [:i|]] timeToRun 691 StackToRegisterMappingCogit: [1 to: 100000000 do: [:i|]] timeToRun 192 192 - 691 / 6.91 -72% SimpleStackBasedCogit: 0 tinyBenchmarks '753495217 bytecodes/sec; 64769127 sends/sec' StackToRegisterMappingCogit: 0 tinyBenchmarks '931756141 bytecodes/sec; 128157989 sends/sec' 931756141 - 753495217 / 7534952.17 -24% 128157989 - 64769127 / 647691.27 -98% SimpleStackBasedCogit: [Compiler recompileAll] timeToRun 47013 (no transcript StackToRegisterMappingCogit: [Compiler recompileAll] timeToRun 43406 (no transcript) 43406 - 47013 / 470.13 -7.67234594686576 The status of this code is essentially beta. The test suite runs the same on the new code generator as on the old, but I think there are still bugs because I get the occasional transient error. I am therefore very interested in any reproducible errors you can find. The VMs (http://www.mirandabanda.org/files/Cog/VM/VM.r2334/) contain a few other important changes: - a bug fix to bytecode<->native pc mappng that produced incorrect results for methods containing blocks with ^-returns in them. One symptom is incorrect highlighting of the pc in the debugger, althoguh symptoms could be much serious. - jitting interpreted methods on backward branches. Currently any interpreted method that performs more than 20 backward branches will be considered for JIT compilation and if it is suitable (default, <= 60 literals) will be compiled to native code. - new callback support. I need to commit some changes to the Alien package to provide access to this but essentially the VM's callback support is now able to be ported to architectures with register-based calling conventions (ARM, PowerPC, SPARC etc). I'll try and get the Alien code released soon, and to back-port the changes to the standard VM before the end of the holiday. One thing that is still /not/ fixed is the lack of a SoundPlugin on win32. Apologies. I'll try and get a fix for this before the end of the holidays too, but time might be too tight. There are other priorities such as harmonising the standard and Cog VMs for the 4.2 release. best Eliot

[Pharo-project] Need help about Sockets
by Adrien BARREAU Jan. 15, 2011

Jan. 15, 2011

Hi all, I'm trying to use the Sockets in Pharo but I don't understand some points. I tried that piece of code: | s c rcv | Socket initializeNetwork. rcv := String new: 400. s := Socket new. s listenOn: 12345. c := s waitForAcceptFor: 30. c dataAvailable ifTrue: [ c receiveDataInto: rcv ] ifFalse: [ self halt ]. waitForAcceptFor: waits a connection, so I opened a telnet client on localhost:12345. It works, but the "accept" primitive always failed. I tried to find some code where it's used: ConnectionQueue>>listenLoop. I assume that method works (but it has no sender), and I don't understand what is different between it and my code. Perhaps I don't try to use the Sockets the good way? Adrien.

[Pharo-project] we will start 1.3 really soon
by StÃ©phane Ducasse Jan. 15, 2011

Jan. 15, 2011

Hi guys there are some minors fixes to be addressed (like the preferences use in dev) but we will go 1.3 probably this evening and we will start to harvest a large list of pending issues. If you have seen fixes in squeak that you think are good please add a bug entry. After that we will plan for the big changes in 1.3 for me I would like to see - collection enh (finishing hashed collection) - weak structure support - announcement using weak structure - file system use - new package implementation (cyrille worked and will continue to really make sure everything works) - real beta of OPAL The goal is to have a release for 1.3 by June/July.

[Pharo-project] Eeekk.. Morphic-Themes are now part of Morphic package
by Igor Stasenko Jan. 15, 2011

Jan. 15, 2011

I was surprised to see it part of morphic. It introducing dependency loop, Actually the name 'Morphic-Themes' was only a suggestion how to name a separate package, but not meant to merge it with Morphic. we should fix that now. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] "Bindable" or "Observable" collections on Pharo/Smalltalk?
by nullPointer Jan. 15, 2011

Jan. 15, 2011

Hi, excuse me for my poor english. Exist some type of collection for bind to widgets like a listView or grid? I want say a special collection than allow know, externally, when a object is added, removed, changed the "current" etc for represent changes on a GUI. For example, I have a collection connected on a grid. When I add or remove a element on collection I have refresh the grid set again the collection like datasource, and select the same object of before. That is hard for the widget when I have very items. I want "capture", with events or others, and remove only the row of grid, and not refresh all again. I donÂ´t know if I do the question correctly.
