I'm not a PSF member, but it seems to me that the PSF could ask Amazon
(or any other virtual machine business anyway) to donate a small number
of permanent EC2 instances in order to run buildslaves on. After all, big
companies often like sponsoring open-source projects, especially when the
project is well-known and the donation is cheap for them.
This would have several advantages:
- the machines are administered by the provider: we don't have to worry
about failed hardware, connectivity loss etc.
- any Python core developer could get ssh access to the VMs to run tests
directly, since they would be dedicated buildbot instances
- they are not tied to a particular owner when it comes to fixing system
problems, which means we eliminate a single point of failure: if a
volunteer gets demotivated/bored/missing in action, someone can replace
- there are a number of various OS images available (of course, we still
need competent people to install the required software -- buildbot, etc.)
Since I've never used any such service ("cloud"-based VMs), I'm not sure
what the downsides would be. But it seems to be that it would be at least
worth trying. Right now we have around 15 buildbots but two thirds of
them are down, the others sometimes fail or disconnect in erratic ways
and it's difficult for "regular" core developers to be aware of what's
precisely going on.
Of course this could also be a broken idea, for whatever reason I'm not
