Re: Buildbot version

[Iago Toral Quiroga <itoral igalia com>]

Hi Ilmar,

As you know we create one master per project, then we create a home page
that queries the state of each master and shows the summary. This
approach has its problems, since you need to open a lot of ports in the
case of big projects like Gnome.

About what the buildbot guys told us, you can find the details in the
mail archive of buildbot:

http://sourceforge.net/mailarchive/forum.php?thread_name=1209036821.6326.41.camel%40marte.wired.citic.igalia.com&forum_name=buildbot-devel

I put here the interesting part:

"I think you may be able to configure a single master with a number of
different waterfall views (exposed at different URLs, eg the current
URLs).

One way to do this is with categories. A single master can have many
buildbot.status.web.waterfall.WaterfallStatusResources, each at a
different URL and each with different configuration. That resource
class accepts a `categories´ argument to its initializer. It will
only include builds from builders which have a `category´ which is
in that list.

For example, here's a snippet from Twisted's buildmaster configuration:

winxp32py25iocp = scmikesWinXP32.copy()
winxp32py25iocp.update({
'name': "winxp32-py2.5-iocp",
'builddir': "WXP32-full2.5-iocp",
'factory': TwistedReactorsBuildFactory(blah blah blah),
'category': 'unsupported'})
builders.append(winxp32py25iocp)

...

status.putChild(
"waterfall",
WaterfallStatusResource(categories=['supported', 'unsupported']))

This gives us a waterfall with all our builders. We have another one
that only includes "supported". So, you could create a category for
each project and then a waterfall for each category. This done, you
should only need one slave process per slave machine, and they can
all talk to the same master."
