[Buildbot-devel] First impressions with 0.9.0b1

[Pierre Tardy]

Hi Vitali,

Thanks again for this detailed review.

Indeed, there are a lot of details that changed that may not be in the
release note.
We made our possible to detect and document the breaking changes for things
that were documented, but indeed there are a lot of installs (including
mine) that are relying on undocumented implementation details.
We hope that for all those details we reworked it to be more easy to work
with, like addStepsAfterCurrentStep.

Also, it is difficult for us to sort out the perfect migration guide, as it
is difficult to know what might be pain point as we ourselves know too much
the details.

We would be glad if you could contribute a migration guide as you think
would have helped you better.


Now some answers on the details that mayhelp you.

- buildbot-www is the main UI, and supposed to be usable. Indeed it is very
configurable, you can create your own pages like the waterfall view. Please
let us now what are the missing features. Indeed, rebuild feature is not
yet supported. It is not a very hard task. nobody happen to work on it yet.

- If the UI locks this is most likely because of a misconfiguration of the
reverse proxy. Please see here how to configure it correctly
http://docs.buildbot.net/latest/manual/cfg-www.html#reverse-proxy-configuration
I don't know where to place this information so that it is easy to find.
This has been a common issue in my experience for my colleagues

- The forceschedulers are supposed to work. I am using them a lot in my
prod, so this would most likely be a configuration problem of some sort. We
can help you to debug

> The sidebar scrolling in/out & resetting to this behavior is really
annoying
Not sure exactly what do you mean.

Regards
Pierre
