Hi. I am loading OCompletion in PharoCore 1.1 while building the Dev image. If I just take a core image, load OCompletion and run tests, they take a lot of time, not acceptable.
Now....if I build a Dev image (with OB, RB, etc) and at the end I try to run OCompletion tests, the tests takes HOURS. The image seems frozen, but actually is working. If I interrupt I see the problem is in ECUntypedModel >> initializeSelectors the part of [ Smalltalk environment keysDo: [ :each | selectors add: (ECGlobalEntry contents: each type: #globalVar) ]. takes a lot of time and it seems related to "ECPreferences caseSensitive" and "ECUntypedModel >> resetSelectors" I don't know what else to say. To reproduce, take a PharoCore 1.1 and evaluate: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOCompletion'; load. (ConfigurationOfOCompletion project version: '1.2') load: 'Core Tests' Then, run all the tests inside OCompletionTests. You will see that after running some threads....it will look like frozen. There, do an interrupt and analize. IF you do that for a Dev image, it takes muuuuch more. I guess this is because "Smalltalk environment keys" will have muuuuuch more elements than a simple core. Anyway, help is appreciated.

My Pharo 1.1 Dev, cog image:
OrderedCollection with an initial size of 500 and without sorting, no case sensitive, - 23 seconds OrderedCollection with an initial size of 500 and without sorting, case sensitive, - 17/18 seconds OrderedCollection with an initial size of 500 and sorting with #sortBy:, no case sensitive - 25 seconds OrderedCollection with an initial size of 500 and sorting with #sortBy:, case sensitive - 21 seconds Hope it helps, cheers Guille 2010/9/26 Levente Uzonyi <[hidden email]>

IF you take a 1.1 core and just load OCompletion:
MessageTally time: [ECContextTest new testUntypedVarsOnly] 20907 If you load OCompletion and the rest of the dev image: MessageTally time: [ECContextTest new testUntypedVarsOnly] 100137 However, IN pharo dev 1.0 it is MessageTally time: [ECContextTest new testUntypedVarsOnly] 7405 sooo.... ???? something has changed? cheers Mariano

But in Pharo 1.0 OCompletion was doing the same....so? did SortedCollection chang between 1.0 and 1.1? If you have n classes in the system, the method takes O(n^2) time. I have already fixed this, though it's not available yet. let us know when this is available.

A preview version is available here: http://leves.web.elte.hu/squeak/Ocompletion-ul.77.mcz It should work in Pharo 1.1, though it has some additional Squeak specific code which is unnecessary for Pharo.

Looks like some changes of ECompletion are then missing in
OCompletion. ECompletion doesn't use Preferences for a long time anymore.

For example the Pharo 1.1 OneClick image has 3220 globals. The sortBlock asks for the preference twice per evaluation. SortedCollection uses a binary search during #add:. If we are optimistic, then the preference is asked 3220 * (3220 ln / 2 ln) * 2 times which is ~75k. In the same image the "old" code asked for the preference 2282899 times during the tests, while the new code did it only 398 times. If the preference is changed to return the value of a variable, then the difference is only 80 ms, otherwise it's 36.6 seconds.

As you see we got trap in a tempest of documents to write :) so do not forget to open bug entry wehn some actions should be taken....
