[Pharo-project] Linking Update Mails to issue tracker
by Torsten Bergmann May 23, 2011

May 23, 2011

Dear Santa, These days I find myself constantly copying and pasting issue numbers to find out the details of a new Pharo update. If it is not too complicated/cumbersome I would like to see the following: When a mail on a new Pharo update is generated/written would it be possible to add not only the issue number and short text but also the issue URL so it links to the issue tracker? So mails in the archive like this http://lists.gforge.inria.fr/pipermail/pharo-project/2011-May/049373.html would directly link to issues like http://code.google.com/p/pharo/issues/detail?id=4257 and one can easily click to find out what the change really is about...

ScaledDecimal would be used where consistency is often more important than accuracy, e.g. in Financial calculations where being off by a few pennies doesn't matter but always getting the same answer matters a LOT. Once a number is converted to a ScaledDecimal computations must always produce the same result assuming enough digits. To ensure this asScaledDecimal must produce a scaled decimal for use in computations and, as such, storing a fraction internally is unacceptable. >From a financial point of view 1/3 * 3 is not 1! >From a programmers point of view asScaledDecimal changes the value in much the same way asInteger does for a float. Having said all of this allow me to contradict myself. It seems to me that a scaled decimal should in general store more digits than are displayed. For example money might be stored with a large (possibly arbitrary) number of digits after the decimal point but only display two digits beyond the decimal point. I don't know how ScaledDecimal is implemented but I would be inclined to use arbitrary or large size integers and store the location of the decimal point internally recomputing the position of the decimal point after each calculation. This is an expensive way of doing computations but I expect users of ScaledDecimal can live with that. When converting non decimal results to ScaledDecimal then how many digits of precision to maintain must be specified somehow. Dealing with ScaledDecimal is a complicated matter and I have probably failed to appreciate many of the complications but whoever is implementing ScaledDecimal (and Smalltalk needs ScaledDecimal) needs to appreciate those complications. Anybody here a financial expert? Ralph Boland

This method is also missing from Pharo 1.2. Anyone knows where to get it from? No idea.. what is it supposed to do? Having two Paragraph implementations in parallel over so many years was not a good idea... Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Complete MethodContext stack for testing
by Mariano Martinez Peck May 23, 2011

May 23, 2011

Hi guys. We need to do some test to serialize a MethodContext to a file, materialize it, and then compare it to the original. One of the problems we face is that some values in the MethodContext are changed so it is difficult to test. So...what we would like is to get a "bottom" MethodContext that we can ask #sender, and to that one #sender, and like that....and the whole stack should cannot be changed. Another problem is that I cannot do a #deepCopy on a MethodContext because #basicNew: throws errror. Is this possible? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] What happens with named primitives in CM ?
by Mariano Martinez Peck May 23, 2011

May 23, 2011

Hi folks. I was inspecting for example the CM of Integer >> #bitAnd: and the first literal is an array like this: #(#LargeIntegers #primDigitBitAnd 0 17) I understand the first and the second elements, but I don't the third and the fourth. What are they? (0 and 17) because then even seem to change their value. I am asking because I am serializing CompiledMethod and then at materialization time I am putting just two zeros for the moment. But I am not sure what they mean. Thanks in advance, -- Mariano http://marianopeck.wordpress.com
