Introduction

Builders that are managed by the coordinator (VMs running on GCE or reverse buildlets, such as the new OS X builders) are listed here:

http://farmer.golang.org/builders

For design details about the coordinator, see http://golang.org/s/builderplan

Older-style builders are listed below. These builders are configured and run manually. The goal is to migrate as many as possible over to the new system.

Builder Requirements

• internet connection (at least be able to access Google and http://build.golang.org)
• preferably with two or more (V)CPUs, as at least one test (sync/atomic requires runtime.NumCPU() > 1 to test more completely)
• at least 512MiB of memory (1GB or more highly recommended. 512MB might need a small GOGC setting to avoid thrashing.)

Restrictions

• The combination of Ubuntu 11.10 or 12.04 OMAP4 kernel and pandaboard (ES) have proven unstable as builders. See issue 4305. Make sure you have updated to the latest available 12.04.2 release.

How to set up a builder

1. obtain a hash from Go team members, and put that in ~/.gobuildkey
2. go get golang.org/x/build/cmd/builder
3. builder YOUR_BUILDER_NAME

Special notes

• Please make sure you‘ve installed root certificates and that it’s accessible to Go programs. For example, on NetBSD, you will need to install security/mozilla-rootcerts.
• If your builder runs Unix, please install perl, as tests for go.tools/cmd/vet need it.
• Use screen(1) instead of tmux(1) to host the builder process, as the later interferes with some of the os/signal tests.
• Raise ulimits on Unix: thread count (-r), nofiles (-n, 1024 should be fine)
