You're suggesting that one organization that contributes to Apache Arrow deserves preferential treatment over others. This is not consistent with Apache project independence https://community.apache.org/projectIndependence.html "Apache projects must be managed independently, and PMCs must ensure that they are acting in the best interests of the project as a whole. Note that it is similarly important that the PMC clearly show this independence within their project community. The perception of existing and new participants within the community that the PMC is run independently and without favoring any specific third parties over others is important, to allow new contributors to feel comfortable both joining the community and contributing their work. A community that obviously favors one specific vendor in some exclusive way will often discourage new contributors from competing vendors, which is an issue for the long term health of the project." > > > > In any case, I think putting the build configurations for the current > > Ursa Labs-managed build cluster in the Apache Arrow repository is a > > good idea, but there are likely a number of issues that we need to > > address to be able to contemplate having a hard dependency between the > > CI that we depend on to merge patches and this tool. > > > > - Wes > > > > On Thu, Sep 5, 2019 at 8:17 AM Antoine Pitrou <anto...@python.org> wrote: > > > > > > > > > Le 05/09/2019 à 15:04, Krisztián Szűcs a écrit : > > > >> > > > >> If going with buildbot, this means that the various build steps need > > to > > > >> be generic like in Travis-CI (e.g. "install", "setup", "before-test", > > > >> "test", "after-test"...) and their contents expressed outside of the > > > >> buildmaster configuration per se. > > > >> > > > > This is partially resolved with the Builder abstraction, see an example > > > > here [1].
