So far we're working on cleaning up the design of basic functionalities before going on. Then, we'll try to find a workaround for non-blocking calls. All ideas are welcome :-) BTW, some people (you included) proposed to help for the Ocean project. Luc and I want to thank you and we are happy that others are willing to help. We thought about the best way to integrate others help. Our conclusion is that we should first do alone (luc and me) the reference design, before integrating other developers. So, we all can work on solid foudations. Noury

IMHO, the simplest way to detect load problems is to load the code (with an automated build). Soon after you save your code, run your build. Then you'll have the red flag raised at the time you want it, so you can fix the problem.

[Pharo-project] Pointer types

by Schwab,Wilhelm K

Sig, You mentioned something that might be useful, depending on where it lives. Our ability to use underscores now leaves me thinking I really should rework some things that suffered mightily: there are some external things that are named assuming underscores, and in mixed case, they turn into an unreadable mess. Along with this, I have a large number of FFI calls that take double pointers, and I have for some time been demoralized into (or stupid enough to<g>) expressing them as void pointers to allow me to pass byte arrays into them. Is there a way that I can get FFI to recognize DOUBLEArray (which uses a ByteArray to hold its data) as something that should be acceptable for a double* call? If not FFI, how does NB handle it?

Re: [Pharo-project] Pool dictionaries = 'private'?

by Schwab,Wilhelm K

I'm having a tough time with a pool dictionary that works in 1.1; there are underscores in the variable names, and 1.1.1 appears to be chopping them up somehow. I recalled having to activate _/:= to get SIXXX loaded, so I quickly tried to file in the offending pool dictionary with the setting disabled, and it worked. The SIXX sar is old, so I am assuming it still contains underscore assignments, and hacked the preference at the right time to (hopefully) allow things to load. OSProcess Command Shell still warns about MVC; it's a drag, because it happens several minutes into my build process :( I'm getting a lot of resistance about something anObsoletePresenter, presumably a reference to a class called Presenter that I added to pacify some Dolphin code, and has slowly taken on a life of its own. There are clearly potenial problems with packages that create hassles on load, and there should be a way to detect them before saving if at all possible. Telling me about it on load is not nearly as much help as would be telling me, prior to saving, that something is wrong, at a time when I can fix it.

[Pharo-project] MC: somebody has to say this

by Schwab,Wilhelm K

I am starting to make a 1.1.1 image; the first step is to save packages so they can hopefully load in the new image. The first step of that is to save my package called Migrate and then to ask it to save everything else. Bugs in Migrate or not, I saw a progress bar mentioning the Pharo in box. That's not acceptable on various fronts. It was cumbersome to add, needed to be added in various packages, and now I find perhaps does things behind my back. Whether or not it did is not the point; it emphasizes another way in which our current system is inadequate. We need real packages, a single-operation way to save all of them to a clearly specified location, and a simple way to separately upload something that has been so saved to the in-box. Migrate is my attempt to help with that; clearly it's not enough. Bill

Tell us when pharo core can be a user. Because we want to clean the mess.

Using any of the clients in Zn will give you a semantically much richer interface to headers and content (entities), both for requests and for responses. And you get many features on top. I haven't looked at the server side, but there too you can get HTTP functionality for free. It will add a dependency though, but I would guess you have one for the server side already, no ?

Re: [Pharo-project] XMLRPC Project - Progress Report

by GermÃ¡n Arduino

Started working on the tests, the current Encoder/Decoder (at client level) works ok. For example, I opened an account on http://snipplr.com (to save useful and interesting Smalltalk snippets) and can connect without problems. Next, some examples: | url proxy r | url := Url absoluteFromText: 'http://snipplr.com/xml-rpc.php'. proxy := XMLRPCProxy new url: url. r := proxy invokeMethod: 'languages.list' withArgs: #('Your snipplr key'). r := proxy invokeMethod: 'user.checkkey' withArgs: #('Your snipplr key'). r := proxy invokeMethod: 'snippet.list' withArgs: #('Your snipplr key' 'pharo'). "To get a snippet you don't need key, but the Snippet ID" r := proxy invokeMethod: 'snippet.get' withArgs: #('41365'). The complete Snipplr xmlrpc API is on: http://snipplr.com/blog/2006/07/06/snipplr-api/ Next step is check the complete API specification (http://www.xmlrpc.com/spec.) to implement all the features at client level. As usual, any comment, suggestion or criticism is more than welcome.

Re: [Pharo-project] Less plugins, more Smalltalk code! (was: Re: Pharo 1.1.1 OneClickCogVm)

by Schwab,Wilhelm K

For Ocean to succeed, you either have to work really hard to make non-blocking calls (I'm thinking of SSL sockets), or you need the ability to call functions on OS threads. The calls need to block their calling Process and let the other Processes run as though nothing is happening. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Noury Bouraqadi [bouraqadi(a)gmail.com] Sent: Sunday, October 03, 2010 4:57 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: [Pharo-project] Less plugins, more Smalltalk code!
