Running tests from Nautilus

by Alexandre Bergel

Hi! Test method of a superclass are not run within Nautilus. Consider: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= TestCase subclass: #ATest. ATest compile: 'test self assert: false'. ATest class compile: 'isAbstract ^ self name == #ATest'. ATest subclass: #BTest. BTest compile: 'test2 self assert: true'. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Selecting BTest in Nautilus and pressing Alt-t says BTest is green. The test runner rightfully says otherwise. We had some yellow test in Moose because of this :-) I have tried to enter a bug issue on https://pharo.fogbugz.com but I could not. In 2 minutes I could not figure out how to create a login and how to see the list of existing bugs. So maybe this one has already been reported.

Re: [Pharo-dev] Barcodes

by Stephan Eggermont

I've committed and merged. That introduces a dependency on Barcode in Artefact. Would you prefer: - creating a separate package depending on both - splitting artefact - making Artefact depend on Barcode - making the dependency the other direction - reverting Stephan

Cloud Hosting why/when?

by Stephan Eggermont

When I see the enthousiast reactions to the cloud hosting tip, I often wonder why? What do you see as the advantages, and where does it provide a good fit? I can understand the 5 euro/month vps for a single instance case. As soon as I need redundancy, monitoring and scaling, I still need to understand so much of the underlying infrastructure that the step to DevOps seems awfully small. Neiher Heroku, nor AWS make scaling transparent, AFAIK. That is to say, they'll start up new instances just fine. That only helps when processing is the problem, not internal bandwidth. And solving the wrong problem only leads to high costs. The cost figures I've seen published on the web suggest that most larger scale usage would be better of with at least their regular demand covered by dedicated servers. I know hosting in the US is much more expensive than in Europe. Digitalocean at least seems to give more reasonable price/performance. AWS vs Hetzner seems uncomparable Your thoughts? Stephan

These processes actually represent various basic services of the system. so i would prefer that these services register themselves somewhere, like that we could have a clean code, something like: services collect: [:each | each process ] like that, you don't need to modify this method evry time you changing the list/implementation etc. > Sven > >> and get 6 processes remain: >> (80) 745275392: Delay class>>handleTimerEvent >> (60) Input events fetching process: InputEventFetcher>>waitForInput >> (60) 1061945344: SmalltalkImage>>lowSpaceWatcher >> (50) 946339840: WeakArray class>>finalizationProcess >> (40s) Morphic UI process: nil >> (10) 845938688: ProcessorScheduler class>>idleProcess >> >> is this OK? >> >> regards. >> >> >> 2013/6/20 Marcus Denker <marcus.denker(a)inria.fr> >> Hi, >> >> I think we should for now just kill them when building the image, I will check. >> >> On Jun 20, 2013, at 9:56 AM, ClÃ©ment Bera <bera.clement(a)gmail.com> wrote: >> >>> Hello, >>> >>> These processes are due to the new integration testing process.
