[Pharo-project] ubuntu and debian support
by Tudor Girba March 6, 2013

March 6, 2013

Hi, Moose 4.7 was just released on top of Pharo 1.4, and now we are moving to Pharo 2.0. In the process of upgrading, we need to get the continuous integration server build on Pharo 2.0. However, the current server is a Ubuntu 10, and it seems that the latest Pharo VM does not run on this machine (as discussed before, I get /lib32/libc.so.6: version `GLIBC_2.15' not found). I understand the need to break loose from old operating systems, and Ubuntu 10 is rather old, but I am limited by the OSs offered by my virtual host provider. The other option would be to use Debian version 6. However, before switching to either another operating system or another provider, I could use some answers to the following questions: - Is the problem with Ubuntu 10 systematic, or can it be solved somehow (perhaps I can install something on my OS to get it to work)? - If it cannot be solved, does the Pharo VM work on Debian 6? - Otherwise, does anyone know a provider that supports the latest Ubuntu (version 12 at this moment) Cheers, Doru -- www.tudorgirba.com "In a world where everything is moving ever faster, one might have better chances to win by moving slower."

[Pharo-project] [2.0 testing] Export / Import Settings Bug + Fix
by MÃ¼ller, Mike March 6, 2013

March 6, 2013

Hi Pharoers, thank you for your time. Here is something you may be interested in: Take the latest image or one-click, open settings browser and click on "Export Settings" to persist them. Then save or not and launch the image again. Exception when reading the preferences from file. You will further notice that the 2 of the 4 generated startup action files are too large. (> 256kb) *Reason:* SettingDeclaration>>startupAction stores some setting values as real thick objects on disk. For example, it writes the standard font definitions as Strike Font Instances, which breaks. *Solution:* In Method "*SettingDeclaration>>startupAction*" replace "storeOn: s" with "settingStoreOn: s" to write the correct startup action format. *Error in consequence:* After applying this fix, you will notice another Exception during the Import, the FreeTypeSystemSettings class wants a method called #noFt2Library:, here I suggest to add that missing accessor with no action. Maybe someone can refactor the (FreeTypeSystem)Settings to have a #readOnly setting which must not be saved to disk. Attached are my 2 changes, after applying them, my image can read all the settings back from the startup files. The startup files created are much smaller (~8kb). This is not exactly clear: "Is every setting materialized from the startup files indeed the original setting?". That would be an interesting test case. Regards, Mike

[Pharo-project] new Cog VMs available
by Eliot Miranda March 5, 2013

March 5, 2013

at http://www.mirandabanda.org/files/Cog/VM/VM.r2697/ CogVM binaries as per VMMaker.oscog-eem.270/r2697 Fix the become issue where methods that are identical are failing the code test because their penultimate literals are different objects. Add a flag "cmUsesPenultimateLit" to jitted methods, stealing bits from stackCheckOffset (which was way larger than needed). Shrink stackCheckOffset to 12 bits (still an order of magnitude larger than needed) and add an error check on assigning it. Also add a check for max method size (2^16-1 bytes) and refuse to jit a method that generates too much code. When comparing code, use the cmUsesPenultimateLit flag to decide if comparison includes penultimate lit or not. This is mildly insane, but the VM really doesn't know about the penultimate literal and it shouldn't depend on knowing it can be ignored. Note that the CoInterpreter knows about the last literal; it uses this in supersends. With this hack, Pharo's condenseSources works. Fix bug in primitiveClone/cloneContext: that causes the copy to be a word short. Use isPointerNonInt: and isContextNonInt: in a few places. Implement unknownBytecode. Send unknownBytecode to the activeContext on unknown bytecode if the selector is in the specialObjectsArray. Fix page size bug in platforms/Cross/vm/sqHeapMap.c. -- best, Eliot

[Pharo-project] Is this possible with XMLWriter?
by Mariano Martinez Peck March 5, 2013

March 5, 2013

Hi guys. I am using XMLWriter from http://www.squeaksource.com/XMLWriter to write a specific XML that a protocol expects. What I need is to build the XML file from parent to children and dynamically. For example, I want to be able to define a tag, but then, later on, add more tags to a parent element. I found this impossible to do with the current XMLWriter. Here, messages like #tag:with: , #with: do not help. I know I will need to build everything in memory and send a "write contents" at the end to get the final XML string... For example, say I wanna build this XML: <root> <parent1> <child1>grrr<child1> <child2>grrr<child2> </parent1> <parent2> <child3>buhhh<child3> </parent2> </root> i would like an API like this: | xmlWriter | xmlWriter := XMLWriter new. xmlWriter tag: 'root'. (xmlWriter named: 'root') tag: 'parent1'. (xmlWriter named: 'parent1') tag: 'child' with: 'grrr'. (xmlWriter named: 'root') tag: 'parent2'. .... xmlWriter write contents. Or even if I don't have #named: but I can store them in instVars it would be fine: | xmlWriter rootTag parent1Tag | xmlWriter := XMLWriter new. rootTag xmlWriter tag: 'root'. parent1Tag rootTag tag: 'parent1'. parent1Tag tag: 'child' with: 'grrr'. rootTag tag: 'parent2' xmlWriter write contents. Any ideas how to do this? Thanks, -- Mariano http://marianopeck.wordpress.com
