[Pharo-project] pharo tests

by Linus De Meyere

Pharo dev's, I'm lurking around the Pharo project for a while now. As I wanted to get some hands-on experience with Pharo I thought it was a good idea to fix an easy bug and see how it goes. The wiki page on how to contribute, and the two screen casts are a great help for newbies like me. Nevertheless, I was wondering if there was an important aspect missing from these instructions: what about tests? I know there is a hudson server running the tests regularly, but I wonder if many people are paying attention to it. Shouldn't there be some instruction on how to add tests for new functionally (or even for a bugfix, if tests weren't already there), and then some instructions on how to run all (or some subset of) the tests to get confidence you didn't broke anything with your changes? How do you, experienced Pharo contributors, go about this? Do you guys run these tests before every check-in? Are there many tests to run? Are there some guidelines to writing tests when contributing to Pharo? Thx, Linus

Re: [Pharo-project] WebClient License Update

by StÃ©phane Ducasse

Bonjour cher andreas >>> For string concatenation on the other hand, we're basically talking about dispersing a whole load of FUD about all the things that "may" go wrong. Fact is, nothing actually *does* go wrong with the change, but the change does fix situations that are *very* difficult to handle otherwise. One of the unfortunate realities of string concatenation is that it's very often used around error messages and logging, often in corner cases that aren't well tested, like: >>> >>> <some impossible condition> ifTrue:[ >>> self log: 'Found impossible condition: ', foo. >>> ]. >> >> I do not buy this argument. We should fix the code and not break the libraries. > > Yes, that is the usual FUD. I know that this is not FUD :) with your code idiom people will start to concatenate object and strings and slowly this will be a terrible mess. Of course you code does not break anything right now. I'm not saying that. Let me clear on that: you can add , on Object if you want but not in Pharo. We do not want coding patterns that do not scale because we will end up in messy libraries. Now you can do whatever you want on your system and we will not use WebClient. There is no problem with that. > Can you clarify how that change breaks any libraries, where and when exactly? Because it doesn't. > >> Your argument is bogus. > > Which one? I made about five different arguments from that this change doesn't break anything, over it preserving the type semantics, that string concatenation often occurs in less tested code, that it is error-prone for no good reason, up until the efficiency argument. > > Or is it simply "I don't like this guy so matter what he says I will not listen"? I let you judge. :) I have no energy for this kind of discussion. I'm over little war and disputes. I'm clean I took the red pill and this is pharo for me. I'm in positive energy, happy people and beautiful flower world now even without smoking strange substances. I decided that I want to build a beautiful world. No energy for the rest. Sorry to cut our non-discussion. A fun note for the headbangers around :) http://www.youtube.com/watch?v=CrctcJqfpXU Suicidal Tendencies - You cannot bring me down (with the bassist of metallica - this is fun to see the gesture of mike muir strange guy but crazy band) I saw them live and it was quite cool (with slayer, megadeth and Testament).

Re: [Pharo-project] Mark and space parity

by Gary Chambers

Generally, settings are stored in flash and changes should be permanent. Though we have had the odd Datalogic unit that tends to suffer from amnesia!

Compiling a new vm is getting to be routine, mostly because I find its diagnostic output to be far less than I typically want when sorting out a problem. Certainly the Windows vm goes out of its way to fail on valid settings and should be changed to allow parity values 3 and 4; the Linux vm might also benefit from relaxing its checks. > > The interesting part is that I don't need to send to the device, only read from it.

There is a fairly extensive book full of barcodes that I believe are for changing the scanner's behavior. In your experience, are such changes stored in persistent store (flash, eprom, etc.), or are they transient such that they typically have to be restored each time the scanner loses power? If I can get it to use something friendly to the vm and stay that way, that might be a good solution. > > Bill > > > > ________________________________________ > From: Tony Garnock-Jones [tonyg(a)lshift.net] > Sent: Saturday, September 11, 2010 1:44 PM > To: The general-purpose Squeak developers list > Cc: Schwab,Wilhelm K; vm-dev(a)lists.squeakfoundation.org; Pharo-project(a)lists.gforge.inria.fr > Subject: Re: [squeak-dev] Mark and space parity > > Hi Bill, > > Based on http://www.lothosoft.ch/thomas/libmip/markspaceparity.php, it looks > like you're set if you need 7S1.

This is because when you have a line split into multiple lines, I want Enter to mean new line, not complete. This is particularly the case when you have pseudo-domain specific languages like in Glamour or Mondrian. Nevertheless, I would say that once I pressed the down arrow, my focus is to the completion, and thus enter should mean selection of the completion.

[Pharo-project] Squeak VM on iPad/IPhone gets open/GL rendering

by John M McIntosh

On friday night I created an open/GL renderer to work with Squeak screen updates on the iPhone/iPad. Unfortunately it runs slows than the tiled Core Animation render that I had work out earlier in the year with help from the Apple graphics engineers. So if anyone has a fair amount of knowledge about Open/GL ES maybe they could contact me and we'll see if we can improve things? -- =========================================================================== John M.
