[Pharo-project] [NativeBoost] New update available
by Igor Stasenko April 30, 2010

April 30, 2010

Hello all. The main direction of work during last days, were introducing a new function formal specification format. With new format, NativeBoost jumps on a next level of flexibility and much less error prone to use!! Here is the old format: primGetModuleFileName: hModule with: lpFileName with: nSize <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #(DWORD 'GetModuleFileNameA' ("in" HMODULE "out"LPCSTR "in"DWORD) ) module: #Kernel32 options: #( - coerceNilToNull ) and here is new: primGetModuleFileName: hModule with: lpFileName with: nSize <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( DWORD GetModuleFileName ( HMODULE hModule, LPTSTR lpFilename, DWORD nSize)) module: #Kernel32 options: #( - coerceNilToNull ) A new format matching very closely to C syntax.. so , for most C functions you can just do a copy-paste! Also, see that formal spec includes an argument names. They are not a dummy ones, but instead should match the argument names of method. In that way, the formal spec can check the argument names and also, takes in account their order on ST stack. So, you can push arguments in different order as you specified in smalltalk method. But that's not all. Besides a formal argument names, a new format also accepts constants , instance variables and special variable - self. Here: alloc: numberOfBytes <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( LPVOID HeapAlloc (self , 0 , SIZE_T numberOfBytes) ) module: #Kernel32 a windoze function takes 3 arguments LPVOID HeapAlloc( HANDLE hHeap, DWORD dwFlags, SIZE_T dwBytes ); but your method takes just one, while other two is 'self' and 0 constant. Instead of just integer literal, you can also use a class variables or pool variables, to make things more convenient and readable: zalloc: numberOfBytes "same as #alloc: but additionally zero-fill the allocated memory" <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( LPVOID HeapAlloc (self , HEAP_ZERO_MEMORY , SIZE_T numberOfBytes) ) module: #Kernel32 And the last thing, is instance variable access. Point>>nbX <primitive: #primitiveNativeCall module: #NativeBoostPlugin > ^ NBFFICallout cdecl: #( sbyte (long x) ) emitCall: [:gen | gen asm pop: gen asm EAX ] here, primitive reads x ivar of Point instance, as a 'long' C value, but on return, converts it to a signed byte value, so: (127@5) nbX 127 (128@5) nbX -128 (-200@5) nbX 56 (5000@5) nbX -120 P.S. Thanks Henrik for a suggestion to change the format! It is now roxxx! :) -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Hacking afternoon starts
by StÃ©phane Ducasse April 30, 2010

April 30, 2010

Hi guys we are starting and we will log on irc but you can also reach me with aol/ichat: sducasse(a)mac.com ICQ: 234273866 the idea is to - fix some bugs in 1.1 - tristan found the problem in the weakDictionary so we will need other people to have a look at it. - integrate/check validate some easy items for you - fix some important bugs. I suggest that we send around mails in this thread when we start to work on an item and we integrate something. In the future we will see if we cannot use the inria infrastcuture to have webcam + videos fun. Stef

[Pharo-project] gettext change set
by Hilaire Fernandes April 30, 2010

April 30, 2010

So far, In the archive the change set of classes (may be there are more) extracted from Etoys for Gettext support. They should install fine in Pharo 1.1, however there are incompatibility issues, look like related to MethodReference protocole (in TranslatedReceiverFind>>findWordsWith:in: ) Probably more to discover after this one. To use the gettext protocol doc http://community.ofset.org/index.php/OLPC#How_can_I_export_the_.pot_file_fo… I use to install DrGeoII package then, try the gettext into it: TextDomainManager registerCategoryPrefix: 'DrGeoII' domain: 'DrGeoII'. ok GetTextExporter2 exportTemplate. fail If someone is interested by a pair hacking session in IRC, drop me a line.

Hi all,+ Could those in the know comment on how this <...> proposal is (or is not) consistent with the fundamental Smalltalk principles that: 1. "an object is send a message and responds with an object" 2. there is no other "magic" in the system. Are we proposing a break fromv this ? If so, IMO we need to really get it right before we commit. Thanks Brent

[Pharo-project] [NativeBoost] new win32 build available
by Igor Stasenko April 29, 2010

April 29, 2010

Hello, i just uploaded a new VM, i built tonight and new NativeBoost code. VM is built from latest SVN + VMMaker + NativeBoostPlugin sources, and now NativeBoost can use all latest additions to interpreterProxy function table, such as addGCRoot, stackPointer etc. And there's already a code which using that, named NBExternalTypeRegistry. It serves as a dictionary of name->object values, where you can register any object under given name and then use it in native code (during native code generation). This is analoguous to what SpecialObjectArray serving for, where you can put an object and then use that object in primitives through well-known index. But in contrast to SpecialObjectArray, a NBExternalTypeRegistry doesn't requires from you to use indexes. You can use just names! Also, it doesn't requires from you to statically assign or initialize the same set of name/value pairs at each image startup. All what you need is just register an object first: NBExternalTypeRegistry current at: #MyName put: #(10 12 13) and then, in your assembler, emit code to load it: NBExternalTypeRegistry current emitOopAt: #MyName generator: gen When your restarting a VM, it makes sure that this registry are initially clean. So, it is get refilled only when some new native methods is generated which are using registry to fetch some named object(s). The most often use of named objects is, of course, instantiating the objects of specific class, like: self typeRegistry emitFetchClass: objectClass generator: gen. proxy instantiateClass: asm EAX indexableSize: 0. Or, checking that argument is of correct type. Here, the method which generates a code to verify that argument class (held in oop) will be an objectClass: validateClassOf: oop generator: gen | asm class | asm := gen asm. class := gen reserveTemp. gen proxy fetchClassOf: oop. asm mov: asm EAX to: class. self typeRegistry emitFetchClass: objectClass generator: gen. asm cmp: asm EAX with: class; jne: gen failedLabel. gen releaseTemps: 1. -- Best regards, Igor Stasenko AKA sig.
