Re: [Pharo-users] Current 3.0 download is broken
It did not solve the issue yet :/, I will have to look into it next week. In any case, I think it would be unrelated to a bootstrap since FileLocator is already lazily initialized.

It is a commercial organization that can decide to do something we don’t like at any time. It is free, so we are the product. Just take a look at sourceforge; - we can do much better than github (but don’t have enough time). We should be using a P2P, bittorrent like system for version control. github != git and whether we use github or now does not matter at all. What matters is that we use technology that is robust and that we have a versioning system that works decentralized. All of that is solved by git. With filetree we have the proper granularity (methods) With github we have an awesome website, such as we have an aweseome website with smalltalkhub, execpt that monticello should be modernized. Sadly the community is too small to achieve that, and inventing yet another versioning tool/system won't help on the short run. Maybe, yes someday in the future we can have our own fancy fully object-oriented versioning system, but IMO that is wasted effort, as git/mercurial come very close to something ideal.

On 2013-11-03, at 21:11, Tudor Girba tu...@tudorgirba.com wrote: Hi, We essentially finished moving Moose to Pharo 3.0 (we still have 6 yellow tests but they needed attention anyway). It took about 4 people looking into issues for a total probably around 2 man-days of effort. The largest impediment was actually SmalltalkHub being down for one day :). What posed problems: - RB visitor now has correct visit* methods instead of accept* methods. The deprecation messages helped quite a bit. This meant (1) that we had to rename in our visitors the methods, and (2) that we had to change the old accept* messages. - RB nodes do not answer to #isLiteral anymore. Instead, they answer correctly to #isLiteralNode so that to avoid confusion with Object#isLiteral. This is good, and this meant that we had to hunt all #isLiteral usages in Moose. - Categories are no longer mapped on RPackages through 1-to-1. This is also good because it is an important step in Pharo. Although originally we said we want to keep 1-to-1, this is probably a better solution now. For Moose, this meant that some of our older tests setup had to be modified a bit to rely on RPackage only. - Some Morphs rely now on Announcements, and this had a little impact on the assumptions we make when we suspend announcements (to avoid infinite loops) that are being sent between Morphic and Glamour. We fixed this in Glamour. - In FileSystem #ensureDirectory was renamed to #ensureCreateDirectory without a deprecation. For this one, we should add a deprecation for the old method. opened an issue for that: https://pharo.fogbugz.com/f/cases/12062/ensureDirectory-and-ensureFile-should-be-readded-with-a-deprecation-message - flatCollect had a conflicting behavior in Pharo. We are now integrating the Moose version so that it returns the same species. - The new SpecDebugger expects the registered Inspector to be based on Spec, and this causes problems with the GTInspector. This problem still has to be fixed in Pharo. All in all, we encountered no significant problems and the problems we faced came from deep into Pharo. So, if your code is not relying directly on RB, RPackage or the Debugger, you are likely to have a smooth transition.

Re: [Pharo-users] Simple Spec Examples
Would it be possible to change the name of the selector?
tree selectedItem: (1 - 11)
for me that implies that the tree contains an actual item (1 - 11).
What you want is maybe, #selectedPath: or #selectedItem:1 withParents:{11}
My general rule is: Each time you have to use an association or a point you do
something wrong..
It is hard to guess what this association should mean, so either make a domain
object to describe
what you encode in the association or use specific selectors that say what the
arguments mean.

x getTree selectedItem. Print It -- 21
x getTree selectedItem:

cheers, ben
There was something missing here at the two levels :)
You can see case 11849[1] fixing the morphic issue
and case 11850 [2] fixing the Spec problem :)
Thanks. I'll try it.
Then your example make me think that using association to describe the
path may lead to an ambiguous situation
True. But to clarify things, ListModel suffers the same ambiguity as
follows...
x := (TestSpec new openWithSpec ; yourself).
x getList items: { 1 . 2 . 3 . 2 . 4}.
x getList setSelectedItem: 2.
... ListModel and Treemodel should be consistent in this respect.
Musing further about this...
In the case of a multi-selection ListModel/TreeModel, it is probably
reasonable to select all matching.
For a single-selection, I'm not sure. Considering ListModel first, maybe
defaulting to selecting the first matching is reasonable, perhaps with a
backup method to select the Nth match. Then again, if the identical object
appears in the list multiple times, then #setSelectedItem: might visually
highlight all occurances while still reporting only a single object with
#selectedItems. I think part of a test would go...
x getList items: { 1 . 2 . 3 . 2 . 4}.
x getList setSelectedItem: 2.
y := x getList selectedItem.
x getList setSelectedItem: y.
z := x getList selectedItem.
self assert: (y = z)
...which actually works so ListModel is cool in that regard - except maybe
an option to visually highlight both 2s would be useful - but as a visual
thing maybe that is a handled outside of ListModel.
Actually that should work the same with multi-selection.
x getList items: { 1 . 2 . 3 . 2 . 4}.
x getList setSelectedItems: { 2. 3 }.
y := x getList selectedItems.
x getList setSelectedItems: y.
z := x getList selectedItems.
self assert: (y = z)
Actually it seems there is no #setSelectedItems:.
How then do you save and restore a multi-selection. e.g
savedSelection := x getList selectedItems.
other code that clears/modifies the selection - like refresh for additional
items
x getList selectedItems: savedSelection.

Re: [Pharo-users] Benchmark
Short Answer: - problemSize is used to calibrate your benchmark, so usually you adapt this value for your machine. And yes you are right, the result is not divided by the problemSize. Long Answer: The typical use case is like this: MathBench benchLoopSinus 1 to: self problemSize to: [ :i | i sin ] Now you have two parameters to modifiy: 1. the number of samples you take (aka, how many times you measure the time of #benchLoopSinus) 2. the problem size (aka, how many times you run #sin inside #benchLoopSinus) You increase (1) to get a more stable result: MathBench run: 1 for debugging. MathBench run: 100 will take a long time, but results are more accurate You modify (2) to change the duration of your benchmark, in my silly example above, the method is quite small and the benchmark would finish too quickly. Rule of thumb is to get the run time of your benchmark (here #benchLoopSinus) in the range of 10ms and more. This way you don't have to worry about the timer resolution used to capture the duration of your method. Does this answer your question?

Re: [Pharo-users] Phexample state keeping
On 2013-07-11, at 11:50, Norbert Hartl norb...@hartl.name wrote: I'm playing with Phexampe because I think that in my current project the setup of test scenarios will be a huge part of the testing. So do it in a structured way reducing doubled initialization procedures should be something good. I'm just wondering how the state is kept between dependent test cases. A Phexample test case returns a value so that value := self given: #shouldHaveCollectedSomeState transfers the state from the dependent test case into the current. What do you do if the state produced is more complex than a single value? I don't remember, but calling multiple times #given:, for each part, doesn't solve this problem? To be honest I don't understand why in a test case that calls #given: a tearDown/setUp cycle is executed between the first and the second test case. I think while using #given: I make the second test case explicitly dependent on the first. Why should I reset state collected by the first before executing the second? I think that is one of the possible approximations. Since in general you cannot say that a testcase is side-effect free (needs teardown) or has some requirements (setup). On the other hand I would rather expect it not to call the setup, especially in the case where the #given is done on the same class/test suite. I only had a look at phexample a while ago, so I don't remember all the details. I think I will do a try this weekend.

Running #pointersTo on those soldiers gives a large collection of pointers. How can I use the computer to filter that list to just those references back to the root object? What do you mean by root object? In any case, if I'm not mistaken, this isn't that easy.

Re: [Pharo-users] implementing #release in a domain object
ok I was not sure of how much you were aware of how the GC works :) second try: In your example it would be enough to cut the connection the ship, everything aboard will be GC'ed as well. Once you cut the connection to a subgraph of objects, and they are no longer reachable from the outside (root objects) the whole subgraph get's garbage collected. In your example: as soon as nobody references a ship anymore it gets garbage collected, as well as all objects that were only reachable via that ship. clearer?

And yes, we will add real benchmarks at some point. But for that we first need dedicated machines, as running them on a virtualized environment doesn't make much sense :/.

What do we need to start? some machines :) as long as they are ours it doesn't really matter what size as long as they only run benchmarks. the current mac slave is not the best choice as it will be under load from jenkins... Anne told me that there is sort of a service from inria where they provide certain machines for benchmarking
