Re: [Pharo-dev] Out of the Box support for launching, browsing and proxy

by Guillermo Polito

I remember playing a bit with proxy settings in Ubuntu a couple of years ago. The thing in ubuntu is that they do not use the typical Unix environment variables to set the proxy but use(or use*d* at the time...) the gconf mechanism from GNOME. A detailed explanation is in here [1]. The code for getting the http settings and others from ubuntu got integrated. https://github.com/pharo-project/pharo-vm/blob/55fbd0b0279998a4a33852f5afb3… We should however take a look and, if it works in latest ubuntu versions we should use it. If not either fix it or throw it away. Also, the other detail is that there is work to do with the proxy settings on the image side: - they are only fetched at startup (so updating while the image is running will not update the image) - it is by default deactivated in other than mac... Here is the code InternetPlugin >> startUp Smalltalk os isMacOS ifTrue: [ self useHTTPProxy ifTrue: [ (self getHTTPProxyHost findTokens: ':') ifNotEmpty: [ :p | NetworkSystemSettings httpProxyServer: p first; httpProxyPort: p second asInteger; useHTTPProxy: true ] ] ifFalse: [ NetworkSystemSettings useHTTPProxy: false ] ] Guille [1] http://stackoverflow.com/questions/7230422/how-to-find-default-proxy-settin… El mar., 10 de mar. de 2015 a la(s) 7:42 p. m., Torsten Bergmann < astares(a)gmx.de> escribiÃ³: > Still there are three basic things I miss hardly in a unified way > from the out of the box PHARO/ PHARO VM for the standard platforms (Unix, > Win, Mac): > > 1. ability to execute another process (to start another executable process > either asynchronous or blocking until the external process is finished) > > 2. ability to open a browser on a URL > > 3.

Re: [Pharo-dev] [Pharo4][Reflectivity] Fix link invalidation + hook generation on MetaLink

by Marcus Denker

I was looking at transforming the AST to take the links into account. Last year with Clara we did that with a AST visitor that copies the AST while transforming it (e.g. adding the code for the before link). But this is not that easy as it sounds when taking the whole picture into account (cached #ast per method, using AST for mapping byte code offset->text and using it in all the tools). for example, this should work: testUninstallLinkAndRun | sendNode link | sendNode := (ReflectivityExamples>>#exampleMethod) ast body statements first value. link := MetaLink new metaObject: nil; selector: #value. âdo nothing" sendNode link: link. self assert: sendNode hasMetalink. self assert: (ReflectivityExamples>>#exampleMethod) class = ReflectiveMethod. self assert: (ReflectivityExamples new exampleMethod = 5). sendNode := (ReflectivityExamples>>#exampleMethod) ast body statements first value. self assert: sendNode hasMetalink. self assert: (ReflectivityExamples>>#exampleMethod) class = CompiledMethod. link uninstall. this means asking the compiled method for an AST *after* putting a link onto an AST node of the method should return an AST where that node actually has that linkâ¦ even after recompiling the method. So I think what we should do is to not change the AST and not even transform it, instead we keep the original and annotate it. We generate AST nodes (small sub ASTs) for the links and annotate the AST with those, then visit them in the visitors later as if they would be part of the AST. e.g. for before, the semantic checker visits the exception added for the links, then ASTTranslator visited them for code generation. This way everything should work. What we need -> finally simplify ASTTranslator so we can actually subclass it and configure a compiler instance to use the subclass. -> implement that plugin infrastructure -> implement ASTTranslator subclass that takes #before into account -> check how much complexity is needed for #aroundâ¦ or #after on methodNode with primitive methods. Does it work for these cases? The change is too big for Pharo4 and will happen in Pharo5.

Re: [Pharo-dev] Status of Pharo VM for FreeBSD

by ClÃ©ment Bera

Hello, About the FreeBSD VM, Holger Freyther worked on it so he's the best person to answer. I think some people used it and it was at least partially working. About your NativeBoost bug on openSolaris, need more information: - Can you confirm that you use an intel processor on your openSolaris machine ? I assume that yes but I ask because solaris were typically running on other processors. NativeBoost, as of today, works only with intel processor. - Do you build the Cog VM or Stack VM ? I mean PharoVMBuild or PharoSVMBuild ? I think the PharoSVMBuild does not include NativeBoost by default, that may be your problem. There's a fix somewhere... - What are you doing with NativeBoost ? Is it FFI only or are you generating and executing hand-written machine code ? If it's FFI only, there might be alternative available working more or less out of the box.

[Slots] add ClassVariableTest and a fix: copy over value when changing a Class Var definition

by Marcus Denker

Tiny improvementâ¦ Imagine a class where the class var TT is already set to 5. Object subclass: #TT slots: { } classVariables: { #TT } category: âPlayGround' now changing that to a special ClassVariable that saves its value not in the binding but somewhere else (like ExampleClassVariable), the value should be copied over on class modification: Object subclass: #TT slots: { } classVariables: { #TT => ExampleClassVariable } category: âPlayGround' this is now fixed with https://pharo.fogbugz.com/f/cases/15112/add-ClassVariableTest-and-a-fix-cop… - tests - when changing a class var to a new kind, make sure to copy the existing value over.

Status of Pharo VM for FreeBSD

by Andreas Wacknitz

Hi all, I have a question regarding the status of the PharoVM for UNIX operating systems, especially FreeBSD. As far as I have seen in the actual sources there is some support for FreeBSD available but for me itâs not clear whether itâs only partial or complete. For me it looks more partial (eg. there are no build instructions for FreeBSD and the default offers are only Mac, Linux and Windows), I havenât tried to build it yet but I am thinking about to do that and want to get an idea about the efforts. I have successfully build a PharoVM for openindiana (an OpenSolaris derivate). It runs both Pharo and Squeak images (at least partially, see below). I bootstrapped this on my Mac and used what was already available low level. Alas it has two problems until now: 1. Sound is not working properly (just a single click when doing some sound output and then silence). 2. NativeBoost is not working (atm it is based on the Linux version of NativeBoost). As my time is very limited (doing everything in my spare time) I would like to get NativeBoost working on openindiana first, and then trying to build an actual PharoVM for FreeBSD. Therefore the question regarding the status of PharoVM for FreeBSD. Of course any hints where to start with the NativeBoost problem would be highly appreciated :) Regards Andreas
