Ben can you open a ticket and we will ask guille and pablo to write a class comment.

REMINDER: TechTalk today, 16hs UTC. This are the links.

by Esteban Lorenzano

Hi, Soâ¦ techtalk is today 16hs. That means: 17hs Europe 16hs UK (and no, this is not a political joke :P) 08hs San Francisco 13hs Buenos Aires 12hs Santiago (I think) â¦ and I donât know other timezones. The links we have for the meeting: youtube channel: http://www.youtube.com/user/nicopasserini/live discord: https://discord.gg/Sj2rhxn The idea is that we will try to give a live presentation and we can use the discord channel to send questions that will be solved. This is a little bit less participative than the other talks, but it was the only way we found to stream video that everybody can see (and that it remain for the future generations ;) ). cheers, Esteban

19430 promoting DelaySpinScheduler from experimental

by Ben Coman

A long time ago the current delay scheduler had been operating long enough to no longer consider it experimental. I've finally got around to renaming the class here.... https://pharo.fogbugz.com/f/cases/19430/Promote-DelaySpinScheduler-from-exp… But trying to do... Delay delaySchedulerClass: DelaySpinScheduler in the post-load is a problem for the CI monkey. That post-load might work fine with the integrator. Or otherwise can someone manually execute it in the image after the slice is integrated. cheers -ben

Re: [Pharo-dev] Image start-up hooks

Look at class refs to SessionManager. I was going to refer you to its class comment but its incomplete. Could someone knowledgeable update the class comment to define what support methods are required and the preferred way to register. I'm a bit confused. I'm familiar with #startUp/#shutDown from Delay, but its not obvious from the list of senders which invokes these. I do see TestSessionHandler defines #startup: and the only sender is #runStartup: But I see it also defines #startupHandler: whose only senders (one step removed) are tests, so how does this method fit into the architecture? cheers -ben On Tue, Dec 13, 2016 at 5:25 PM, Michel Onoff <michel.onoff(a)web.de> wrote: > Hi, > > is there a way to register arbitrary code to be run at image start-up and > shutdown? > > Thanks > Michel > >
