[Pharo-project] some thoughts on coding practices.
by John M McIntosh Sept. 6, 2009

Sept. 6, 2009

Today I was faced with trying to consolidate some overrides for the iPhone work and faced the following issues: Or perhaps it just wasn't my day to do software development on the EuroStar. (a) I need really to extend or subclass InputEventSensor (1) I'm not really sure how to best add instance variables to InputEventSensor via MC. (2) I wanted to make a subclass, but then discovered RFBServer which I need actually hard codes a reference to InputEventSensor versus saying InputEventHandler defaultClass (or something) (3) RFBEventSensor then cheefully subclasses InputEventSensor which defeats my proposed subclass, not sure how in MC I could change the class hierarcy of someone else. (b) RBSpellChecker only picks between macintosh and other, so adding a subclass for iPhone means hacking startup for RBSpellChecker, versus having the more standard iteration over subclasses and having them choose who can do the work. Also if it's not macintosh that does not mean it's iPhone, or windows, risc, or unix... These both seemed hurdles to getting somthing productive done so I'll welcome comments about how to make it easier. -- = = = ======================================================================== John M.

[Pharo-project] Finding unpackaged methods
by Schwab,Wilhelm K Sept. 6, 2009

Sept. 6, 2009

Hello all, Are there any existing tools that will, for example, find all methods marked with a specific author and not in a given list of packages? At least I _think_ that's what I want :) I have been extending an install script that I used to initially create the image I am using, and it might be best converted to a list of packages known to a builder that could also help look for methods that might be about to be left behind. I am thinking ahead to moving to a later beta and fearing leaving important code behind. Clearly I will keep my current image and be able to return to it, but some good tools could help avoid a lot of frustration. Some of my concern is over a few strange things that I've noticed about SIF's response to Dolphin's virtual categories. Bill

[Pharo-project] How do I get the user directory?
by Damien Pollet Sept. 6, 2009

Sept. 6, 2009

aka $HOME or ~/ There is SecurityManager default untrustedUserDirectory but on my machine this returns '/Users/damien/Library/Preferences/Squeak/Internet/My Squeak' and SecurityManager default secureUserDirectory but this one returns nonsense like '/foobar/tooBar/forSqueak/bogus' Besides I have no idea what an untrusted user directory is. Perhaps a Windowsish concept ? -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

[Pharo-project] OpenSSL
by Schwab,Wilhelm K Sept. 6, 2009

Sept. 6, 2009

Stef, Esteban, I would be very open to FFI but them immediately start to wonder about OS threads. From what I remember of the OpenSSL non-blocking calls, somebody else can do that part - I'll use threads. Dolphin has what are called overlapped calls that are made on a separate thread. Originally, it pulled from a pool of threads. The latest version might ensure that all calls from a given Smalltalk process are made on the same OS thread. My requests for such a feature in Squeak/Pharo have always been met with "yeah, you could do that if you wanted" or something along those lines. Ideally, I would hope the FFI gurus would embrace it and do it properly. Have they done so? Bill

I'm post an issue http://code.google.com/p/pharo/issues/detail?id=1173 Looks like call of aDisplayText form: in MorphicUIManage>>composeFormFor: is redundant Found during trying to run InterpreterSimulator (i realy want to help improve project). After i add accessor, i recieve an DNU of ByteSymbol>>coerceTo:sim: Is any have any idea. Is this method missing in VMMaker package or removed in Pharo.

[Pharo-project] latest Pharo-dev... where are the refactoring tools?
by Esteban Lorenzano Sept. 6, 2009

Sept. 6, 2009

Hi, I downloaded latest pharo dev (since a few versions ago), and I noted the changes in the browsers, to O2Browser, and droping OBEnhancement (which was too slow, I think). The change is cool, we have faster browsers, but now I lost all those wonderful refactoring tools... Is there a way I can get them back? is there a refactoring browser or something? Cheers, Esteban

[Pharo-project] Building a VM and/or plugins
by Schwab,Wilhelm K Sept. 6, 2009

Sept. 6, 2009

Hello all, Is there a correct place to start for a Pharo VM? I do not have a mac; Linux is of interest and Windows is currently an obligation born of inertia. So far, I have found mentions of the need to put the sources in a conspicuous location, but I have yet to find whether that has happened or where to look for the code. Various hassles and some accumulated success have me increasingly motivated to get SSL working. I realize this will trigger some well-intentioned mentions of stunnel and the cryptogrpahy package, but OpenSSL is the answer in my case. Stunnel can be misconfigured (or not configured at all), and I really cannot defend the crypto package against anything from FUD to tough questions. IIRC, I couldn't even load it the last time I tried. The question then becomes whether to connect to OpenSSL via FFI/Alien or to make a plugin. One absolute requirement is that the image not turn to stone when an address is wrong, a peer crashes, or a router gets unplugged w/o warning. The most obvious solution to me (please speak up if you disagree) is to connect/bind, read/write and disconnect on a connection-specific OS thread. Any insights to help get there would be greatly appreciated. Bill
