I like the idea of an opt-in Xgrid system, whereby users could opt-

some folks might interpret it as too much big-brother, but really
it's just so common now to have integrated network clusters with
two-way traffic. The opt-in and security settings on the facility
may need integrity checking (code review - so specific commit
rights and few maintainers with security access) and community
monitoring to ensure security. Just about every major desktop
system around has some kind of automated process monitoring and opt-
in bug reporting (windows, mac OSX, gnome, etc.). I guess that
Xgrid provides a nice platform for a distributed build system.
I have no idea where to start with macports base. If I had time to
learn it, I would try. Even so, I would hate to screw around with
it without knowing what I'm doing. Is there any documentation on
how to get started with hacking macports base - any kind of sandbox
to play around with?
Anyone know how to work with Xgrid? It's something on my todo
list, but I've not read anything about it yet.
Before we can allow arbitrary users to submit their builds to a
central server, we would need to ensure that a build that occurs on
one user's system is *identical* to the build on any other user's
computer. This cannot currently be assured because MacPorts does not
build in a chroot, and without this, it is possible for a port to
link with libraries that happen to be on the user's system that it
ought not link with -- be they libraries from other ports on which
the port in question does not declare a dependency, or libraries in /
usr/local, to which the compiler always looks.
Therefore, a build farm that we control is a better option. Which, as
explained in other threads, cannot happen until the software to do
the automated builds in the clean environment is written.
