I asked for this on July 2016... so maybe they have a different offering for open source now.

Keeping slave online is not that much of a work.

I don't know when and where this was discussed. My issue is that I am checking https://github.com/twisted-infra/braid and there was no update for the removal of the slaves in the buildmaster configuration. > So maybe what's more interesting is that CircleCI offers a way to replace > those - with either VM or container (including custom-image) builders. I don't think that Circle-CI provides support for FreeBSD10, RHEL7, Debian 8 and 9. I think that Rackspace still offers us generous resources, so we can use Rackspace for that. We can run 1 or 2 Windows slaves in Azure as they gave us $150 monthly credit. ----- I think that we should find a way to make it super simple to run more tests on local systems. It might not be easy to run all 2.7 / 3.4 / 3.5 / 3.6 on Windows / Linux / BSD/ OSX, but maybe we can find a simple script which runs the core tests in under 1 minute. Devs will then be asked to run these tests before pushing to a PR... and in the same time these teste can be used as stage 1. If they don't pass we don't spin OSX / Windows and other resource-heavy tests. ------- On Appveyor we have 4 builders/jobs Maybe we can stage Windows test... and execute iocp reactor only after select tests pass... on 2.7. We still have Windows on Buildbot, so maybe run fewer tests on Appveyor (to speed it up), since we will run all Windows tests anyway in Buildbot. ---- For external contributors, we are effectively now running the tests in 2 stages Unless Travis and Appveyor don't pass, we don't manually trigger the Buildbot tests. -------- When I have time, I will retry Circe-CI for OSX. Just to give it a spin and see where we are and how much time we need per month for OSX. I think that we can tune the number of tests we run on Circle-CI to get into the budget. The Circle-CI can server as a stage-1 builder for external contributors... and we will still have the OSX slave maintained by Glyph. > Jean-Paul > >> >> >> I am happy to try again with Circle-CI >> >> ------ >> >> We might go over 500 minutes.
