Re: Incompatability of all existing pyarrow releases with the next NumPy release
I believe we can do a release that is just focused on the Python artifacts, yes. On Mon, Dec 7, 2020 at 6:52 AM Joris Van den Bossche wrote: > > On Fri, 4 Dec 2020 at 21:11, Uwe L.

Demise of Ursabot CI jobs
hi folks -- I just wanted to confirm that the Ursabot CI jobs that went down a few weeks ago won't be coming back, at least not in the Buildbot form factor. The Buildbot master was hosted on a physical machine which suffered some kind of network configuration problem during a Linux update that I don't have the sysadmin skills to resolve, so that machine has been wiped and with it the Buildbot setup. There are some jobs that were being run on these machines (CUDA, large memory tests) that still need to be run. I highly recommend that we move these to physical machines that report in to our free Buildkite org (https://buildkite.com/apache-arrow), that way things will be less brittle and machines can easily come and go without any involvement from ASF Infra (which is why I've been against self-hosted GitHub Actions). Thanks, Wes

It would at least ensure that plain pip installs with latest versions will work (while it doesn't solve it for older pyarrow releases of course, in case people upgrade numpy in an existing environment, or install numpy with pyarrow pinned to an older version). Does our project governance allow doing a python-only release? (meaning, a release branch where the 2.0.1 tag compared to 2.0.0 tag only includes changes to the python libraries) That would make it less burdensome to resolve part of this situation. > Is anyone objecting to this approach? > > Cheers > Uwe >
