Hi, Below is the coverage we currently have in buildbot. It's not terribly complete but I suspect it does reflect what people are actually testing and care about.
In terms of policy, we should consider buildbot coverage as a requirement for a platform/architecture to be fully supported. Fully supported means (1) that code will be rejected/reverted if it breaks one of these platforms (2) breaking these platforms will be a release blocker. Anything that isn't fully supported is best effort only. Note that are some things missing from buildbot today (like an ARM host) that there is strong interest in having as a fully supported platform. Host Arch --------- s390 (offline since May 1st) PPC Sparc (offline since 2011) x86_64 i386 Host OS ------- Solaris 11 (offline since 2011) Debian 6.0 RHEL 6.1 RHEL 5.x Fedora 16 OpenBSD (current) OpenBSD 4.9 Mingw32 MacOS X Regards, Anthony Liguori
