[LLVMdev] LLVM buildbot infrastructure

[Galina Kistanova]

Hello everyone,

We have a number of issues with the current buildbot infrastructure.
During this week I will be addressing 2 which I think are most
important.

1. There is no well specified dependencies, so all builders get
triggered by any change in any of watched projects. I.e. lldb change
triggers clang build and versa versa.
2. If a project depends on multiple others, sequential changes could
be split to different builds and make wrong blame lists.

I will be changing the way how LLVM buildbot watches changes in the
source tree, how builders are grouped, and how builders depend on
projects.

I will try to do as much as possible without restarting the
buildmaster, and restart it late nights when that cannot be avoided.
But somebody will see some disturbances anyway. Sorry for this and
thanks for your understanding.


Thanks

Galina
