[devel at bb.net] Porting buildbot to Python 3, status report and request for help

[Craig Rodrigues]

Unfortunately, I don't really find the output of the graph
to be very understandable.  It doesn't give me a good understanding of what
percentage of
buildbot tests are passing on Python 3, and what are failing, what the
progress is.....and I'm working on this stuff!

One limitation of Travis is that stdout/stderr output of a Travis job is
limited
to something really low, like 4 MB.  This is inconvenient because we want to
say the names of the tests being run, in addition to any error messages
from failing tests.

To move forward on this, the work that you do in setting up buildbot-based
Python 3 builders
will be critical.  It will allow us to see the full output of tests
passing/failing on Python 3,
without the stdout limitations of Travis.

It will also give confidence to buildbot users that this is solid stuff.

I hope the work I am doing will help the buildbot community.  Although
there is a lot of competition
in the CI/CD space these days, I think that buildbot has a lot to offer in
this space, and I hope
it stays vibrant and relevant.
Jumping on the Python 3 bandwagon is a pain in the neck initially,
but it is the direction that Python is going in, so helps the code be
vibrant and relevant.
