Re: [Pharo-project] HashTable vs Dictionary

[Pharo-project] [update 1.1] #11018

by StÃ©phane Ducasse

11018 ----- - Issue 1258 Number-readFrom-followUp There is no use invoking SqNumberParser with failBlock: [^ self error: ...] because this is the default behaviour... - Fix FontTest>>#testResetAfterEmphasized. aFont derivativeFonts cannot be assumed to store emphasized versions indexed by their emph code. - adds squeezeNumberOutOfString: to Number, as discussed in the Pharo workshop. On the way, it fixes an issue in SqNumberParser, where it would return itself rather than the result of the failblack, when parsing fails. Also, a test is added to test and document the new squeezing number out of strings behavior.

[Pharo-project] Traits composition question

by Igor Stasenko

Suppose i having a trait grouping Trait named: #TraitGroup uses: TraitA + TraitB + .... TraitN category: 'foo' and suppose i want to use TraitGroup in one of my classes, but excluding one of the traits in the list above.. i.e. something like: Object subclass: #Myclass uses: TraitGroup - TraitA .. but the above code don't seem to work.. Any clues, how i can do that? Is such kind of composition possible at all? -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Feature request: All uses of Trait

by Igor Stasenko

It would be cool to have a 'references-to' support for traits. Or maybe its there already? How can i quickly look, what classes using the trait? -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] hashing collections

by Ralph Boland

Food for thought: In my finite state machine generator I do a lot of hashing of sometimes large collections. For performance reasons I created hash value storing versions of the relevant collection classes. Getting the hash value of the hashed version of a collection was then very fast (accessing an instance value) and the hash values were good. For example, for Array I created HashArray The hash value of a HashArray was the XOR of the hash values of the elements of the HashArray. Note that this meant that each time you changed the entry in a HashArray you had to update the hash value. So for HashArray at: index put: object would look something like: hash := (hash xor: object hash) xor: (self at: index). super at: index put: object. If you like living on the edge you could instead leave out updating the hash value until you put the HashArray object where its hash value would be needed (like a Set or Dictionary (key)). This is of course error prone but then putting collections in Sets or Dictionaries (keys) is inherently error prone anyway because modifying the collection changes its hash value thus breaking every Set or Dictionary containing the collection. I would be temped to have all real collection classes (e.g. not Interval) not be storable in Sets or Dictionaries (key) at all and instead require hash versions of the collection be used but of course this would surely break a lot of things.

I agree there are opportunities for improvement in Pharo's packages but I see the attempt to lump _all_ examples in a single package as a backward move. I think a better approach would be similar to the on going discussion on the tests packages. We should have the package for the specific functionality, some convention on the test (generally Unit Test, which some argue also make as some part of the usage examples) related package, and some convention on example related package. I would argue even further that we should have a documentation related package, but that will digression right now! my .019999.... -- Cesar Rabak

Re: [Pharo-project] Broken "Recover Lost Changes"

I loaded the changes file into Emacs, deleted everything except the changes since the last save point, and then I got errors on the Traits code. I then deleted those line, and managed to filein the code successfully. I have a copy of the image and changes file that was made just before I had the crash.

Re: [Pharo-project] (a = b) => (a hash = b hash)

by Andres Valloud

Nicolas, > Yes, large Array hash has severe performance penalty anyway. > Maybe we shall not hash each and every element. > I disagree. The issue is that if hashing a very large array (or string) becomes a performance problem, then we should engineer applications so that we hash the metadata as opposed to the data. In other words, assume you're hashing arbitrary 1kb strings. You can't have more than ~1 million of those in memory at any given time, and there are only so many you can store in a database. Chances are those 1kb strings represent chunks of data that can be uniquely identified with no more than e.g.: 64 bits. Then, just hash those 64 bits and be done with it. In the absence of assumptions on the hashed data, though, you have no option other than to hash everything. > And, even forgetting about equality with Array, Inteval>>#= and > Interval>>#hash do not agree in Squeak and Pharo: > > (1 to: 10 by: 5) = (1 to: 9 by: 5). -> true > (1 to: 10 by: 5) hash = (1 to: 9 by: 5) hash. -> false > > Sometimes the end points of intervals are important... maybe it's better to have equality fail than "fixing" hash in this case.
