Go Reference

golang.org/x/build/dashboard

Package dashboard contains shared configuration and logic used by various pieces of the Go continuous build system.

Deploying

When adding or removing builders, or changing a builder's build policy (which repos/branches get tested), you need to deploy the x/build/cmd/coordinator binary. Additionally, you usually want to re-deploy the x/build/app/appengine code to update https://build.golang.org/. The latter is only for humans (forcing columns to show up and adding the little black dots on cells that aren't built), but doesn't affect what gets built.

const GoBootstrap = "go1.17.13"

GoBootstrap is the bootstrap Go version. Bootstrap Go builds with this name must be in the bucket, usually uploaded by 'genbootstrap -upload all'.

Variables

var Builders = map[string]*BuildConfig{}

Builders are the different build configurations. The keys are like "darwin-amd64" or "linux-386-387". This map should not be modified by other packages. Initialization happens below, via calls to addBuilder.

Hosts contains the names and configs of all the types of buildlets. They can be VMs, containers, or dedicated machines.

Please keep table sorted by map key.

Types

type BuildConfig

type BuildConfig struct {
	// Name is the unique name of the builder, in the form of
	// "GOOS-GOARCH" or "GOOS-GOARCH-suffix". For example,
	// "darwin-386", "linux-386-387", "linux-amd64-race". Some
	// suffixes are well-known and carry special meaning, such as
	// "-race".
	Name string

	// HostType is the required key into the Hosts map, describing
	// the type of host this build will run on.
	// For example, "host-linux-amd64-bullseye".
	HostType string

	// KnownIssues is a slice of non-zero go.dev/issue/nnn numbers for a
	// builder that may fail due to a known issue, such as because it is a new
	// builder still in development/testing, or because the feature
	// or port that it's meant to test hasn't been added yet, etc.
	//
	// A non-zero value here means that failures on this builder should not
	// be considered a serious regression and don't need investigation beyond
	// what is already in scope of the listed issues.
	KnownIssues []int

	Notes string // notes for humans

	CompileOnly bool // if true, compile tests, but don't run them
	FlakyNet    bool // network tests are flaky (try anyway, but ignore some failures)

	// RunBench enables benchmarking of the toolchain using x/benchmarks.
	// This only applies when building x/benchmarks.
	RunBench bool

	// MinimumGoVersion optionally specifies the minimum Go version
	// this builder is allowed to use. It can be useful for skipping
	// builders that are too new and no longer support some supported
	// Go versions. It doesn't need to be set for builders that support
	// all supported Go versions.
	//
	// Note: This field currently has effect on trybot runs only.
	//
	// TODO: unexport this and make buildsRepoAtAll return false on too-old
	// of repos. The callers in coordinator will need updating.
	MinimumGoVersion types.MajorMinor

	// SkipSnapshot, if true, means to not fetch a tarball
	// snapshot of the world post-make.bash from the buildlet (and
	// thus to not write it to Google Cloud Storage). This is
	// incompatible with sharded tests, and should only be used
	// for very slow builders or networks, unable to transfer
	// the tarball in under ~5 minutes.
	SkipSnapshot bool

	// StopAfterMake causes the build to stop after the make
	// script completes, returning its result as the result of the
	// whole build. It does not run or compile any of the tests,
	// nor does it write a snapshot of the world to cloud
	// storage. This option is only supported for builders whose
	// BuildConfig.SplitMakeRun returns true.
	StopAfterMake bool

	// InstallRacePackages controls which packages to "go install
	// -race <pkgs>" after running make.bash (or equivalent).  If
	// the builder ends in "-race", the default if non-nil is just
	// "std".
	InstallRacePackages []string

	// GoDeps is a list of of git sha1 commits that must be in the
	// commit to be tested's history. If absent, this builder is
	// not run for that commit.
	GoDeps []string

	// CrossCompileConfig optionally specifies whether and how
	// this build is cross compiled.
	CrossCompileConfig *CrossCompileConfig
	// contains filtered or unexported fields
}

A BuildConfig describes how to run a builder.

func TryBuildersForProject

func TryBuildersForProject(proj, branch, goBranch string) []*BuildConfig

TryBuildersForProject returns the builders that should run as part of a TryBot set for the given project. The project argument is of the form "go", "net", "sys", etc. The branch is the branch of that project ("master", "release-branch.go1.12", etc) The goBranch is the branch of Go to use. If proj == "go", then branch == goBranch.

func (*BuildConfig) AllScript

func (c *BuildConfig) AllScript() string

AllScript returns the relative path to the operating system's script to do the build and run its standard set of tests. Example values are "src/all.bash", "src/all.bat", "src/all.rc".

func (*BuildConfig) AllScriptArgs

func (c *BuildConfig) AllScriptArgs() []string

AllScriptArgs returns the set of arguments that should be passed to the all.bash-equivalent script. Usually empty.

func (*BuildConfig) BuildsRepoPostSubmit

func (c *BuildConfig) BuildsRepoPostSubmit(repo, branch, goBranch string) bool

BuildsRepoPostSubmit reports whether the build configuration type c should build the given repo ("go", "net", etc) and branch ("master", "release-branch.go1.12") as a post-submit build that shows up on https://build.golang.org/.

func (*BuildConfig) BuildsRepoTryBot

func (c *BuildConfig) BuildsRepoTryBot(repo, branch, goBranch string) bool

BuildsRepoTryBot reports whether the build configuration type c should build the given repo ("go", "net", etc) and branch ("master", "release-branch.go1.12") as a trybot.

func (*BuildConfig) DistTestsExecTimeout

func (c *BuildConfig) DistTestsExecTimeout(distTests []string) time.Duration

DistTestsExecTimeout returns how long the coordinator should wait for a cmd/dist test execution to run the provided dist test names.

func (*BuildConfig) Env

func (c *BuildConfig) Env() []string

Env returns the environment variables this builder should run with.

func (*BuildConfig) FilePathJoin

func (c *BuildConfig) FilePathJoin(x ...string) string

FilePathJoin is mostly like filepath.Join (without the cleaning) except it uses the path separator of c.GOOS instead of the host system's.

func (*BuildConfig) GOARCH

func (c *BuildConfig) GOARCH() string

func (*BuildConfig) GOOS

func (c *BuildConfig) GOOS() string

func (*BuildConfig) GoBootstrapURL

func (c *BuildConfig) GoBootstrapURL(e *buildenv.Environment) string

GoBootstrapURL returns the URL of a built Go 1.4+ tar.gz for the build configuration type c, or empty string if there isn't one.

func (*BuildConfig) GoInstallRacePackages

func (*BuildConfig) IsContainer

func (c *BuildConfig) IsContainer() bool

func (*BuildConfig) IsLongTest

func (c *BuildConfig) IsLongTest() bool

IsLongTest reports whether this is a longtest builder. A longtest builder runs tests without the -short flag.

A builder is considered to be a longtest builder if and only if its name ends with "-longtest".

func (*BuildConfig) IsRace

func (c *BuildConfig) IsRace() bool

func (*BuildConfig) IsRestricted

func (c *BuildConfig) IsRestricted() bool

func (*BuildConfig) IsReverse

func (c *BuildConfig) IsReverse() bool

func (c *BuildConfig) IsTryOnly() bool

func (*BuildConfig) IsVM

func (c *BuildConfig) IsVM() bool

func (*BuildConfig) MakeScript

func (c *BuildConfig) MakeScript() string

MakeScript returns the relative path to the operating system's script to do the build. Example values are "src/make.bash", "src/make.bat", "src/make.rc".

func (*BuildConfig) MakeScriptArgs

func (c *BuildConfig) MakeScriptArgs() []string

MakeScriptArgs returns the set of arguments that should be passed to the make.bash-equivalent script. Usually empty.

func (*BuildConfig) MatchesSlowBotTerm

func (c *BuildConfig) MatchesSlowBotTerm(term string) bool

MatchesSlowBotTerm reports whether some provided term from a TRY=... comment on a Run-TryBot+1 vote on Gerrit should match this build config.

func (*BuildConfig) ModulesEnv

func (c *BuildConfig) ModulesEnv(repo string) (env []string)

ModulesEnv returns the extra module-specific environment variables to append to this builder as a function of the repo being built ("go", "oauth2", "net", etc).

func (*BuildConfig) NeedsGoProxy

func (c *BuildConfig) NeedsGoProxy() bool

func (*BuildConfig) NumTestHelpers

func (c *BuildConfig) NumTestHelpers(isTry bool) int

NumTestHelpers reports how many additional buildlets past the first one to help out with sharded tests.

isTry specifies whether it's for a pre-submit test run (a TryBot or SlowBot) where speed matters more.

func (*BuildConfig) OutboundNetworkAllowed

func (c *BuildConfig) OutboundNetworkAllowed() bool

OutboundNetworkAllowed reports whether this builder should be allowed to make outbound network requests. This is only enforced on some builders. (Currently most Linux ones)

func (*BuildConfig) PrivateGoProxy

func (c *BuildConfig) PrivateGoProxy() bool

PrivateGoProxy for builder has it's own Go proxy instead of proxy.golang.org

func (*BuildConfig) ShouldRunDistTest

func (c *BuildConfig) ShouldRunDistTest(distTest string, isNormalTry bool) bool

ShouldRunDistTest reports whether the named cmd/dist test should be run for this build config. The isNormalTry parameter is whether this is for a normal TryBot (non-SlowBot) run.

In general, this returns true. When in normal trybot mode, some slow portable tests are only run on the fastest builder.

Individual builders can adjust this policy to fit their needs.

func (*BuildConfig) SplitMakeRun

func (c *BuildConfig) SplitMakeRun() bool

SplitMakeRun reports whether the coordinator should first compile (using c.MakeScript), then snapshot, then run the tests (ideally sharded) using cmd/dist test. Eventually this function should always return true (and then be deleted) but for now we've only set up the scripts and verified that the main configurations work.

type CrossCompileConfig

type CrossCompileConfig struct {
	// CompileHostType is the host type to use for compilation
	CompileHostType string

	// CCForTarget is the CC_FOR_TARGET environment variable.
	CCForTarget string

	// GOARM is any GOARM= environment variable.
	GOARM string

	// AlwaysCrossCompile controls whether this builder always
	// cross compiles. Otherwise it's only done for trybot runs.
	AlwaysCrossCompile bool
}

CrossCompileConfig describes how to cross-compile a build on a faster host.

type HostConfig

type HostConfig struct {
	// HostType is the unique name of this host config. It is also
	// the key in the Hosts map.
	HostType string

	// HostArch is a string identifying the host architecture, to decide which binaries to run on it.
	// If unset, it is derived in func init from the HostType
	// (for example, host-linux-amd64-foo has HostArch "linux-amd64").
	// For clarity, the HostArch for 32-bit arm always ends in -5 or -7
	// to specify the GOARM value; implicit HostArch always use -7.
	// (This specificity is necessary because there is no one value that
	// works on all 32-bit ARM chips on non-Linux operating systems.)
	//
	// If set explicitly, HostArch should have the form "GOOS-GOARCH-suffix",
	// where suffix is the GO$GOARCH setting (that is, GOARM for GOARCH=arm).
	// For example "openbsd-arm-5" for GOOS=openbsd GOARCH=arm GOARM=5.
	//
	// (See the BuildletBinaryURL and GoBootstrapURL methods.)
	HostArch string

	// GoBootstrap is the version of Go to use for bootstrap.
	// A bootstrap toolchain built with that version must be in the bucket.
	// If unset, it is set in func init to GoBootstrap (the global constant).
	//
	// If GoBootstrap is set to "none", it means this buildlet is not given a new bootstrap
	// toolchain for each build, typically because it cannot download from
	// storage.googleapis.com.
	//
	// (See the GoBootstrapURL method.)
	GoBootstrap string

	// Exactly 1 of these must be set (with the exception of EC2 instances).
	// An EC2 instance may run a container inside a VM. In that case, a VMImage
	// and ContainerImage will both be set.
	VMImage        string // e.g. "openbsd-amd64-60"
	ContainerImage string // e.g. "linux-buildlet-std:latest" (suffix after "gcr.io/<PROJ>/")
	IsReverse      bool   // if true, only use the reverse buildlet pool

	RegularDisk    bool   // if true, use spinning disk instead of SSD
	MinCPUPlatform string // optional. e2 instances are not supported. see https://cloud.google.com/compute/docs/instances/specify-min-cpu-platform.

	// GCE or EC2 options:
	//
	// CustomDeleteTimeout is an optional custom timeout after which the VM is forcibly destroyed and the build is retried.
	// Zero duration defers decision to internal/coordinator/pool package, which is enough for longtest post-submit builds.
	// (This is generally an internal implementation detail, currently left behind only for the -perf builder.)
	CustomDeleteTimeout time.Duration

	// Reverse options
	ExpectNum       int  // expected number of reverse buildlets of this type
	HermeticReverse bool // whether reverse buildlet has fresh env per conn

	// Container image options, if ContainerImage != "":
	NestedVirt    bool   // container requires VMX nested virtualization. e2 and n2d instances are not supported.
	KonletVMImage string // optional VM image (containing konlet) to use instead of default

	Owners []*gophers.Person // owners; empty means golang-dev
	Notes  string            // notes for humans

	SSHUsername string // username to ssh as, empty means not supported
	// contains filtered or unexported fields
}

A HostConfig describes the available ways to obtain buildlets of different types. Some host configs can serve multiple builders. For example, a host config of "host-linux-amd64-bullseye" can serve linux-amd64, linux-amd64-race, linux-386, linux-386-387, etc.

func (*HostConfig) BuildletBinaryURL

func (c *HostConfig) BuildletBinaryURL(e *buildenv.Environment) string

BuildletBinaryURL returns the public URL of this builder's buildlet.

func (*HostConfig) ContainerVMImage

func (c *HostConfig) ContainerVMImage() string

ContainerVMImage returns the base VM name (not the fully qualified URL resource name of the VM) that starts the konlet program that pulls & runs a container. The empty string means that no particular VM image is required and the caller can run this container in any host.

This method is only applicable when c.IsContainer() is true.

func (*HostConfig) IsContainer

func (c *HostConfig) IsContainer() bool

func (*HostConfig) IsEC2

func (c *HostConfig) IsEC2() bool

IsEC2 returns true if the machine type is an EC2 arm64 type.

func (*HostConfig) IsHermetic

func (c *HostConfig) IsHermetic() bool

IsHermetic reports whether this host config gets a fresh environment (including /usr, /var, etc) for each execution. This is true for VMs, GKE, and reverse buildlets running their containers running in Docker, but false on some reverse buildlets.

func (*HostConfig) IsVM

func (c *HostConfig) IsVM() bool

IsVM reports whether the instance running the job is ultimately a VM. Hosts where a VM is used only to initiate a container are considered a container, not a VM. EC2 instances may be configured to run in containers that are running on custom AMIs.

func (*HostConfig) MachineType

func (c *HostConfig) MachineType() string

MachineType returns the AWS or GCE machine type to use for this builder.

func (*HostConfig) PoolName

func (c *HostConfig) PoolName() string

PoolName returns a short summary of the builder's host type for the https://farmer.golang.org/builders page.
