TestPGConnection>>testNotify2 fails
by Esteban A. Maringolo Oct. 14, 2015

Oct. 14, 2015

I have a failing test in my computer when running the test mentioned in the subject, I get the following error: "PGConnection has a defective state machine" Stack: PGConnection(Object)>>error: PGConnection(PGActiveObject)>>stCantHappen: PGConnection>>stCantHappen: PGConnection(PGActiveObject)>>processEvent: PGConnection(PGActiveObject)>>generateEvent:to: PGConnection(PGActiveObject)>>saProcessEventsUntil: PGConnection>>copy:withStream: TestPGConnection>>testNotify2 I tested in my computer with Pharo4, Pharo3 and Pharo2, and I get the same error in all the images with the latest version of it, and also with the oldest I could load (in Pharo 2, Name: PostgresV2-Maiano.24). My PostgreSQL server version is 9.3.7. Does it fail for you too? Regards! Esteban.

About Magritte Seaside
by stepharo Oct. 14, 2015

Oct. 14, 2015

Hi guys How can I get Magritte seaside (and a working version not one breaking on XML I do not what)? I loaded the published stable version of Magritte into Pharo and there is no seaside version. I checked the configuration and it is so complex.... I have the impression that we need to distinguish Magritte from Magritte seaside. So I will do a separate configuration of magritte seaside. Stef

Corporate sponsored popularity
by Ben Coman Oct. 14, 2015

Oct. 14, 2015

Just a passing thought... When comparing the popularity of programming languages, maybe technological features are less important than sponsorship by a large tech corporation. Anyhow I don't mind that the masses haven't discovered Pharo. I enjoy it. http://insights.dice.com/2015/10/13/apples-swift-is-killing-objective-c/ cheers -ben

Question about implementation of a delay
by Ferlicot D. Cyril Oct. 14, 2015

Oct. 14, 2015

Hi, I am building a widget for fast table in order to filter them for Synectique and Pharo. For now I have a Rubric editor where we can write a pattern and I use a Rubric announcement to update the Fast Table. So each time the rubric is update the method #update is call. At the beginning #update was: ---- pattern := self patternFromString: filterField getText asString trimBoth. fastTable dataSource: (initialDataSource newDataSourceMatching: pattern). fastTable refresh ----- But this will update the Fast Table at each character, so I want to add a delay. For example I want to let the user type and update the table if he don't type for 0.2second. The only way I found is this: ---- update: anAnnoucement | pattern timeStamp | timeStamp := DateAndTime now. timestamp := timeStamp copy. [ (Delay forMilliseconds: 200) wait. timeStamp = timestamp ifTrue: [ pattern := self patternFromString: filterField getText asString trimBoth. fastTable dataSource: (initialDataSource newDataSourceMatching: pattern). fastTable refresh ] ] fork ---- But I think that create a new process a each update is really too heavyâ¦ So I would like to have some advices from experienced people to know if there is a better way to implement a delay. If you want to check the code you can execute: ---- Gofer new smalltalkhubUser: 'estebanlm' project: 'FastTable'; configuration; load. (Smalltalk globals at: #ConfigurationOfFastTable) loadDevelopment. FTFastTableComposer browse ---- -- Cyril Ferlicot http://www.synectique.eu 165 Avenue Bretagne Lille 59000 France

Hi, we have lots of issue that stay on the issue tracker far to long as there are not many people actively reviewing/testing/commenting. it would really be helpful to have more people involved. https://pharo.fogbugz.com/f/filters/36/Fixed-to-Review Marcus

taskbarThumbnail leaks memory?
by Henrik Nergaard Oct. 14, 2015

Oct. 14, 2015

It looks like the taskbarThumbnails might be leaking memory. When moving the mouse across the taskbar viewing the different thumbnails the memory usage increases by quite a lot (viewed in the taskmanager (Windows) ). I made an example script to illustrate the resource usage. Test scenario: 20 windows; 1 Playground, 19 Nautilus browsers (these are minimized). =============== Create Test Scenario ======================== 19 timesRepeat: [ Nautilus openOnClass: Object. World doOneCycle. ]. World doOneCycle. World submorphs select: [ :m | m isKindOf: NautilusWindow ] thenDo: [ :m | m minimize ] ===== Enumerate the mouse moving from one taskbarButton to the next ======= | delay | delay := [ :msToWait | | t | t := Time now asMilliSeconds. [ (Time now asMilliSeconds - t) < msToWait ] whileTrue: [ World doOneCycle ]. ]. 20 timesRepeat: [ World submorphs detect: [:m | m isTaskbar ] ifFound: [ :taskbar | taskbar orderedTasks collect: [ :task | task morph ] thenDo: [ :morph | | button | button := (taskbar taskButtonOf: morph). morph taskbarButtonEntered: button event: nil in: nil. delay value: 100. morph taskbarButtonLeft: button event: nil in: nil. delay value: 100 ] ]. Smalltalk garbageCollect. ]. ============================================================ Results: (Newest Win vm -> Image 50377) opening the 20 Windows RAM used is 70MB. 1 iteration: 93MB 20 iterations: 130MB \ 190 MB when garbageCollect is commented out. Should the resource usage be that high? (a taskbarThumbnail is deleted before the next one is shown...) Best regards, Henrik

[Reflectivity] A small Demo: Execution Metalink Demo Plugin for Nautilus
by Marcus Denker Oct. 14, 2015

Oct. 14, 2015

Hi, With Miguel Campusano we build a small demo. There is a "Execution Metalink Demoâ Plugin for Nautilus. "A demo of Metalink usage: when it is installed, it glows red when the selected method is executed somewhere in the systemâ If you install it and open a new browser, there is a strange morph in the middle position. every time you select a method, it installs a meta-link there that calls a method on the morph to make it red. Then the morph has a #step method to get darker step by step. -> activate the plugin -> open new browser -> go to Array>>#asArray and see how it glows e.g. when moving the window Note: -> if you select the ârightâ methods, the image will freeze (meta-recursion, we do not use meta-level aware links yet) -> somehow the metalinks do not get GCed (but it seems the actual de-installing works). The idea is that it is for now just a demoâ¦ but when the framework gets stable, it is an example of what we can do with it. Marcus
