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

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.

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

by Andres Valloud

I'd rather make the interval not equal to the array, at least with the message #=. Probably that can't be done safely. If that's the case, I'd say the best approach is to leave it "broken" but documented in terms of "some collections may compare 'reasonably', however, since equality in those cases is not well defined, then the rule a = b => a hash = b hash may be waived". For example, sure, #(1 2 3) = (1 to: 3), however you can't do (1 to: 3) at: 2 put: 5. And 1.0 may be equal to 1, but the numbers represent completely different things so even though the numeric value is the same, equality is ill defined, and so it's not necessary for the hashing rule to apply.

Re: [Pharo-project] about selectorsDo: versus selectors do:

Yes !

Re: [Pharo-project] question about results of MessageTally

by Schwab,Wilhelm K

Jannik, A good starting point is wiki.squeak.org/squeak/4210 I am not an expert on this, but the profiler works by sampling from a high priority process that looks at what the "slow ones" happen to be doing at the time - it's random, but done enough times, a picture will emerge from it. In this case, you have not profiled creating a dictionary, you have profiled adding elements to a dictionary. If you want to see creating the dictionary, something like MessageTally spyOn:[ 1000 timesRepeat:[ Dictionary new. ]. ]. would be a better choice. If you want to see the effects of adding the elements, you might create the dictionary outside the block to remove it from the profile.

For example: === |n| MessageTally spyOn:[ n := Dictionary new. 1 to: 400000 do:[:each | n at: each put:each]. ] === returns this results: ==== - 1745 tallies, 1751 msec. **Tree** -------------------------------- Process: (40s) 1964: nil -------------------------------- 45.8% {802ms} Dictionary(Set)>>atNewIndex:put: |43.6% {763ms} Dictionary(Set)>>fullCheck | |39.4% {690ms} Dictionary(Set)>>grow | | |27.2% {476ms} Dictionary>>noCheckAdd: | | | |25.2% {441ms} Dictionary(Set)>>findElementOrNil: | | | | |23.6% {413ms} Dictionary>>scanFor: | | | | |1.6% {28ms} primitives | | | |2.0% {35ms} primitives | | |9.2% {161ms} primitives | | |3.0% {53ms} Array(SequenceableCollection)>>do: | |2.4% {42ms} primitives | |1.8% {32ms} SmallInteger(Magnitude)>>max: |2.2% {39ms} primitives 22.4% {392ms} Association class>>key:value: |18.9% {331ms} Association class(LookupKey class)>>key: | |16.3% {285ms} Association(LookupKey)>>key: | |2.6% {46ms} primitives |1.9% {33ms} Association>>value: |1.6% {28ms} primitives 4.4% {77ms} Dictionary(Set)>>findElementOrNil: |2.3% {40ms} primitives |2.1% {37ms} Dictionary>>scanFor: 1.9% {33ms} primitives ==== But, if I do: === |n| MessageTally spyOn:[ n := Dictionary new. 1 to: 4000000 do:[:each | n at: each put:each]. ] === results are: ==== - 179772 tallies, 180312 msec. **Tree** -------------------------------- Process: (40s) 1964: nil -------------------------------- 3.1% {5590ms} Dictionary(Set)>>atNewIndex:put: |2.8% {5049ms} Dictionary(Set)>>fullCheck | 2.3% {4147ms} Dictionary(Set)>>grow | 1.3% {2344ms} Dictionary>>noCheckAdd: 1.0% {1803ms} Association class>>key:value: ==== Where are the rest of the process ? Does anybody understand this behavior ? can you explain ?
