But in another image (where I am having the problem), if I try to connect to the Monticello repository (served by HTTPS by nginx in the other server) I do have the problem and in this case I am trying to communicate via HTTPS from Pharo. Wouldn't be using Zodiac here? Ah, I misunderstood. Yes, to access an HTTPS based repository, you need Zodiac. If all Zn+Zdc tests are green, that means you are good. I see that you get a ConnectionTimedOut error while connecting, that's like the very first step ;-) What I would do is: make sure you can access your HTTPS repo in other ways, using a regular browser and/or curl. You know, MC repo serving is just plain HTTP(S) with basic authentication: you should be able to list a repo or download a version using any other means. If that works, try to do the same using ZnClient, like this: ZnClient new username: 'marianopech' password: 'secret'; get: 'http://www.smalltalkhub.com/mc/SvenVanCaekenberghe/STON/main/Ston-Core-SvenVanCaekenberghe.35.mcz'.

Re: [Pharo-dev] [Pharo-project] Understanding NBOpenGL
Igor got you will try to avoid using #sizeOf: , even for a readability I can replace it with a simple method returning the same thing depending in platform. Now because I am confused lets clarify how the whole things works because I see many errors in my code and clearly I don't understand how Nativeboost works. Note I am a C noob , so excuse me if I say anything stupid here. As far as functions call are concerned I see 3 possible scenariors a ) function(int var). Here the C function expects a simple variable of some type (int in this case) according to what you told me to make such variable I will do var := Nativeboost allocate:( NBExternalType typeof:'int') if I want to pass a value in that variable then I will do var nbInt32AtOffset: 0 put: 6 will call that function with Object function: var b) function(int* var) how I create the variable (pointer) ? how I put value in the variable (pointer) ? c) function( var) Now I assume I will create a var variable same way as (a) var := Nativeboost allocate:( NBExternalType typeof:'int') but how I pass the address of var to the function ? I read the pdf of nativeboost but It did not clarify those things or simply I did not understand. Thanks on the instructions about NBExternalArray. So the reason of using this object is for convenience ?

Transcript show: ' I am putting to vpos in index: '; show: i-1; show:' value: '; show: each value; cr. ]. so far so good. just one small advice: do not use #sizeOf: sparingly.. it parsing the type and doing full type resolution when you do that. you can remember the size of the type you need at boot/startup time, there is no chance it can change within same session :) but of course for demonstration purposes and readability it good. now the tricky part is that I have a function that expects that Array , not the smalltalk version but the C version we just created gl bufferData_target: GL_ARRAY_BUFFER size: vptrsize data: ... usage: GL_STATIC_DRAW. where you see the dots is where I should pass the data, in this case the C array I could do a vpo nbFloat32AtOffset: but that will return me only the individual value at the specific point (index) of the array, while I want to pass the entire array. So how I do that ? I explored NBExternalAdress and I cant find something that would return an array. Am I missing something obvious here ? just pass NBExternalAdress instance as argument and you done. NBExternalAdress value , returns the number of the address and not that data contained in that address. I also see a NBExternalArray but I am not sure if it is what I should be using . arrayClass := NBExternalArray ofType: 'float'. array := arrayClass new: 5. or externalNew:5 , if you want to allocate it in external memory array at: 1 put: 10.1 use just like normal Array to pass it to function use: self soemFunction: array address.

Re: [Pharo-dev] [Pharo-project] Understanding NBOpenGL
Igor one last thing I forgot to ask about b) how I pass the pointer to the function ? Now Camillo , If you guys care about making pharo popular , I mean really popular you should stop caring what you want or what I want and care more about what most people want. Democracy sucks but hey thats the way to fame. I am sorry but I am not buying into the whole argument of self documented code. Why ? Because I dont trust coders. I know however for a fact that as you said it outside documentation , assuming its a lengthy one, even if its a bad one, is a much safer bet to make sense , especially for a very big library. If the library is very small sure you can deal with it with class comments and method comments and some random examples. But take Nativeboost for example, understanding Nativeboost without outside documentation is just , well crazy. There so many issues to discuss and many concepts to analyse, and if we take into account that people dealing with Nativeboost are not C coders or experienced with C coding then you will have loads of user with a big questionmark on top of their heads. Sure those people should go read a C code, which I do already , but still would I complain if documentation of NB explained those things to me ? Why would I , I am as lazy as the next person. Plus I am a user why should I care about class comments and methods comments, I dont care how the source works I only care how I can use the library the easiest , quickest way possible. Should classes and methods have their comments ? definitely !!! This is open source , its meant to be read , analyzed and modified. Making people life harder is making it more close source. But I dont believe a user of a library would prioritize class / method comments and code example over old-way hardcore documentation. I seriously believe pharo would greatly benefit from a wiki and would help taking it more seriously. Or at least an included documentation tool inside pharo that will make documentation much easier. I mentioned wikibooks because its based on already highly successful popular technology. If you have better recommendation I am open to any ideas. So in short yes I will comment class/methods of Nativeboost and yes I will contribute to wikibooks as well. Camillo Bruni-3 wrote I like to see people contributing :), maybe you could do some contribution on the code-side? I personally consider well written, executable examples more valuable than written documentation outside the image. And I think NativeBoost could benefit from some in-image documentation.

Hi Thierry, You were right in asking for stat/fstat. The unix stat() call provides the uid and gid of the file, so those values are provided by primitiveFileStat. In order to determine if the file is e.g. readable, you need that information along with the file protection mask (also provided by primitiveFileStat), and of course you need to know the uid and gid of your VM process, see primitiveGetUid, primitiveGetGid, primitiveGetEUid and primitiveGetEGid in UnixOSProcessPlugin.

The name is just a sequence of bytes. The safe way is check for system encoding using nl_langinfo(CODESET) and encode/decode strings passed to and from OS to whatever internal representation is used to store strings. So far this works good on our systems.

On 2 July 2013 16:27, kilon theki...@yahoo.co.uk wrote: Igor got you will try to avoid using #sizeOf: , even for a readability I can replace it with a simple method returning the same thing depending in platform. Now because I am confused lets clarify how the whole things works because I see many errors in my code and clearly I don't understand how Nativeboost works. Note I am a C noob , so excuse me if I say anything stupid here. As far as functions call are concerned I see 3 possible scenariors a ) function(int var). Here the C function expects a simple variable of some type (int in this case) according to what you told me to make such variable I will do var := Nativeboost allocate:( NBExternalType typeof:'int') if I want to pass a value in that variable then I will do var nbInt32AtOffset: 0 put: 6 will call that function with Object function: var you found very interesting way to pass simple integer to function :) if your function is 'function(int var)' you call it directly: someobject function: 5 x := 10. someobject function: x etc.. b) function(int* var) how I create the variable (pointer) ? how I put value in the variable (pointer) ? pointer = address on memory which holding some value. every time you see '*', it means that function expects pointer. And of course, since that function will write or read from that memory location, it is your responsibility to provide a pointer to valid data, with enough size etc. So, the way how you did for first case, is actually applicable for this case. But it is not necessary to use externally allocated memory. Sometimes you can safely use object memory, e.g.: buffer := ByteArray new: 4. someobject function: buffer. c) function( var) did you meant 'int var'? because otherwise it is not correct declaration. Now I assume I will create a var variable same way as (a) var := Nativeboost allocate:( NBExternalType typeof:'int') but how I pass the address of var to the function ? this is reference (more from C++).. which in fact just a syntactic sugar, function still expecting pointer (so consider this to be same as *var) I read the pdf of nativeboost but It did not clarify those things or simply I did not understand. Thanks on the instructions about NBExternalArray. So the reason of using this object is for convenience ? Of course. It is more convenient to deal with array of typed elements (of type you need), than manually deal with bunch of raw bytes. Igor Stasenko wrote On 1 July 2013 20:40, kilon thekilon@.co wrote: Thanks Igor , yes I was aware of String Cr because I have done some googling around and it did find information on the subject. Apparently it failed because I had an error in my source. So for our next challenge is learning how to fetch data that a pointer points to. in this case I have an array that contains my vertex positions , called vertexPositions vertexPositions the positions of vertices to be passed to opengl ^ #( 0.75 0.75 0.0 1.0 0.75 -0.75 0.0 1.0 -0.75 -0.75 0.0 1.0 ) so far so good so I create a pointer for that array vptrsize := (NBExternalType sizeOf: 'float')* self vertexPositions size. and then take that pointer and insert in each position the individual values from vertexPositions vertexPositions withIndexDo: [:each :i | using nbUInt32AtOffset because we know pointer is 4 bytes :) vpos nbFloat32AtOffset: (i-1)*(NBExternalType sizeOf: 'float') put: each value. Transcript show: ' I am putting to vpos in index: '; show: i-1; show:' value: '; show: each value; cr. ]. so far so good. just one small advice: do not use #sizeOf: sparingly.. it parsing the type and doing full type resolution when you do that. you can remember the size of the type you need at boot/startup time, there is no chance it can change within same session :) but of course for demonstration purposes and readability it good. now the tricky part is that I have a function that expects that Array , not the smalltalk version but the C version we just created gl bufferData_target: GL_ARRAY_BUFFER size: vptrsize data: ... usage: GL_STATIC_DRAW. where you see the dots is where I should pass the data, in this case the C array I could do a vpo nbFloat32AtOffset: but that will return me only the individual value at the specific point (index) of the array, while I want to pass the entire array. So how I do that ? I explored NBExternalAdress and I cant find something that would return an array. Am I missing something obvious here ? just pass NBExternalAdress instance as argument and you done. NBExternalAdress value , returns the number of the address and not that data contained in that address. I also see a NBExternalArray but I am not sure if it is what I should be using . arrayClass := NBExternalArray ofType: 'float'. array := arrayClass new: 5. or externalNew:5

Ok, i will follow the issue on github. Thanks! 2013/7/1 Dale K.

Thanks for the answer Dale. The drawback in this case is to specify a particular dependency to AsmJit in my configuration. Also, perhaps is the right way since i realized i have a particular dependency on it. But this discussion makes me thing a little and so i have a new question. Form what I (mis) undestand from Metacello, when asking for a bleedingEdge version it loads only the baseline that specifies packages and then last version of every package specified there. As in the projects referenced on the baseline there is no need for specifying a version, and that's the case of nativeBoost configuration, wouldn't it be interesting to have some behavior (i mean i new method for loading like loadDeepSymbolic:) that not only load the symbolicVersion of the package asked, but also propagate that symbolicVersion (bleedingEdge in this case) to all the dependencies that don't specify a concrete version? Guido. Guido, With the Metacello Scripting API[1] I've taken a slightly different tack, but I think that it gets you to the same place. I am a big fan of deterministic loads, but I know that from a practical point of view developers need to have a certain amount of control over exactly what gets loaded into their DEVELOPMENT environments and they need to be able to exert this control without having to resort to editing configurations to match their specific requirements. I have accomplished this by arranging for a Notification to be signalled whenever a project is referenced during a load. The developer can use one or more of the onUpgrade:, onDowngrade: and onConflict: clauses in their load scripts to exert fine control over what happens on a project by project basis ... For your specific use case, I would think that you would want to use the `lock` command[2] and specify that you want to `lock` the projects (NativeBoost and AsmJit) to the #bleedingEdge version. I don't recall if I've got test cases for symbolic versions, but if you are seriously interested in taking the Scripting API for a spin, I'd be willing to write some additional tests using the #bleedingEdge symbolic version (if not already covered) and validate this use case... I am entering a phase where I will be doing some work on getting FileTree and Metacello up to snuff for Pharo3.0 so this would be a good time for me to add some test cases in anticipation of having some interested users ... I haven't released the Scripting API, because I need to have real users with real use cases take the API for a spin and validate the API. The Scripting API can be loaded into any version of Pharo/Squeak/GemStone and I think the Scripting API is (or will be) available in Pharo3.0. I'm looking forward to getting feedback as to how the API stands up to real use ... So let me know if you are interested in being another Scripting API guinea pig:) Dale [1] https://github.com/dalehenrich/metacello-work/blob/master/docs/MetacelloUserGuide.md [2] https://github.com/dalehenrich/metacello-work/blob/master/docs/MetacelloUserGuide.md#locking

Re: [Pharo-dev] [Pharo-project] Understanding NBOpenGL
Thank you Igor for the clarifications, the reason why I prefer using the nativeboost methods is because : a) I was not sure if smalltalk types map correctly to C types and which Smalltalk types correspond to which C types b) many opengl functions ask for the address of the value and the value itself. And I have no clue how to obtain memory addresses of smalltalk types. c) I was not sure whether Pharo VM or garbage collector would move my data making my pointers invalid. But if you say its ok, I trust you. When exactly is ok to use smalltalk types ? -- View this message in context: http://forum.world.st/Understanding-NBOpenGL-tp4686514p4696955.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
