Refactoring squeak
by Damien Cassou 03 Jul '06

03 Jul '06

Hi, sometimes when I dive into Squeak source code, I would like to refactor some piece of code that can be enhanced. Does someone care to have better source code in Squeak ? Where is the best place to post the enhancements ? To post new tests ? Often, it will be just one line or two, do I need to write bug reports in mantis ? Will somebody have a look at this ? Bye

[bug]About this system answers Squeak3.9**alpha**
by Noury Bouraqadi 02 Jul '06

02 Jul '06

Hi, I'm in a train, so I don't have access to the web and hence no access to Mantis for reporting the following bug. When clicking on the 'About this system' button in the Squeak flap, it displays 3.9alpha instead of 3.9beta.

Re: TypeInference: File based way of thinking
by Gerardo Richarte 02 Jul '06

02 Jul '06

Hi Damien > Hi, > I'm currently interested in type inference. RoelTyper works by: Francisco Garau worked on his Thesis on Type Inference in Squeak, and the result was a quite complete Type Inference system working on Squeak. I spent some time trying to find a URL for it, but I couldn't. Everything seems to point to the now extinct swiki.net (http://typeinference.swiki.net). I think that you should be able to find it looking for it some more time, or at least use it as pointer to find other related work. If you finally give up finding his work, and unsuccessfully tried to contact him, and are still interested, let me know. gera

Pragma statements in 3.9b-7035
by Andrew Tween 01 Jul '06

01 Jul '06

I am adding support for pragmas (or maybe that should be pragmata ?) to Shout, and I have noticed the following... testPragma <fred jim bill> compiles without error, and yields a Pragma with keyword=#fredjimbill and arguments=#() Is this the correct behaviour, or should I submit a bug report? Cheers, Andy

Monticello Profiling
by Philippe Marschall 01 Jul '06

01 Jul '06

Hi Loading of Monticello packages in the current 3.9 is already much faster thanks to Adrian. But I think it's still far from optimal. So I did a trace of loading several packages with Monticello (attached). The parts I find interesting 29.0% {75168ms} PackageInfo>>includesClass: 28.0% {72576ms} RBParser class(Class)>>category 11.7% {30326ms} Delay>>wait (sent by EventSensor>>wait2ms) More the 10% of the time is spent doing nothing. Although Class >> #category has seen a major speedup (thanks Adrian) it's still a bottleneck. Cheers Philippe

Yes. >Where is the best place to post the >enhancements ? To post new tests ? Often, it will be just one line or >two, do I need to write bug reports in mantis ? Do you need to write a bug report on mantis? How would you respond to your own question? My experience is that when I find something that bothers me about a piece of squeak. I need to write the mantis report first. Then when I dive into it I have a place to put my partial results. Analysis etc. And when I triumph over the code my fixes and enhancements go there also. . > Will somebody have a look at this ? Will it be interesting to look at? Have you included a good recipe for reproducing the bug? Is your explanation of code enhancements clear? Have you a good answer to the question: What makes it worthwhile? You will find it interesting. You put it there. Whether someone else will depends on whether its in their field of interest. And on whether theyve discovered reading mantis can be more interesting than follow the mailing list. There are a few of us who look at new mantis issues regularly (if they are in our field of interest). I have had mantis issues that have attracted outside attention and ones that have remained mine for long periods of time. Markus Denker in his work on 3dot9 harvested a LOT of code reported in mantis issues. Mantis is patiently persistent. An issue there has a better chance of getting noticed eventually than the mail list. A lot of people add bugs to mantis then include the url in a mail post to draw attention to it. If you report a bug here and its a good one, someone will suggest you put it on mantis, so why not beat them to the punch? Squeak is meant to be iterative. Good code review and good Simplifing refactorings would improve its next iteration greatly. I hope you go for it.
