Functions 

func BuilderIDLink(b, project string) string

BuilderIDLink gets a builder link from builder ID and project. Depends on routes.go.

func UpdateBuilderForBuild 

func UpdateBuilderForBuild(c context.Context, build *BuildSummary) error

UpdateBuilderForBuild updates the appropriate BuilderSummary for the provided BuildSummary, if needed. In particular, a BuilderSummary is updated with a BuildSummary if the latter is marked complete and has a more recent creation time than the one stored in the BuilderSummary. If there is no existing BuilderSummary for the BuildSummary provided, one is created. Idempotent. c must have a current datastore transaction.

Types

type Bot 

type Bot struct {
	// Name is an identifier for the Bot.  This is usually a short hostname.
	Name string
	// URL is a link to a bot page, if available.
	URL string
	// Status is the current status of the Bot.
	Status BotStatus
	// LastSeen denotes when the Bot was last seen.
	LastSeen time.Time
}

Bot represents a single job executor.

type BotPool 

type BotPool struct {
	// PoolID is an identifier for the BotPool.
	// PoolID must match the Descriptor.
	// This field should always be constructed with PoolID().
	PoolID string `gae:"$id"`

	// Descriptor uniquely describes this BotPool.
	// It is defined as Swarming Dimensions + Hostname.
	Descriptor PoolDescriptor

	// Bots is a slice of bots in the pool, along with their statuses.
	Bots []Bot `gae:",noindex"`

	// LastUpdate is when this entity was last updated.
	LastUpdate time.Time
}

BotPool is the execution pool information associated with a set of Swarming bots. This information is periodically refreshed from Swarming.

type BotStatus 

type BotStatus int

BotStatus indicates the status of a machine. 

const (
	// Idle means the bot is ready to accept a job.
	Idle BotStatus = iota
	// Busy means the bot is currently running a job, or recently finished
	// a job and may not be ready to accept a new job yet.
	Busy
	// Offline means the bot is neither ready to accept a job nor
	// currently running a job.  The bot could be dead or quarantined.
	Offline
)

func (BotStatus) String 

func (i BotStatus) String() string

type BuildSummary 

type BuildSummary struct {

	// BuildKey will always point to the "real" build, i.e. a buildbotBuild or
	// a buildbucketBuild. It is always the parent key for the BuildSummary.
	// The parent build may or may not actually exist.
	BuildKey *datastore.Key `gae:"$parent"`

	// Global identifier for the builder that this Build belongs to, i.e.:
	//   "buildbot/<mastername>/<buildername>"
	//   "buildbucket/<bucketname>/<buildername>"
	BuilderID string

	// Global identifier for this Build.
	// Buildbot: "buildbot/<mastername>/<buildername>/<buildnumber>"
	// Buildbucket: "buildbucket/<buildaddr>"
	// For buildbucket, <buildaddr> looks like <bucketname>/<buildername>/<buildnumber> if available
	// and <buildid> otherwise.
	BuildID string

	// The LUCI project ID associated with this build. This is used for ACL checks
	// when presenting this build to end users.
	ProjectID string

	// This contains URI to any contextually-relevant underlying tasks/systems
	// associated with this build, in the form of:
	//
	//   * swarming://<host>/task/<taskID>
	//   * swarming://<host>/bot/<botID>
	//   * buildbot://<master>/build/<builder>/<number>
	//   * buildbot://<master>/bot/<bot>
	//   * buildbucket://<host>/build/<buildID>
	//
	// This will be used for queries, and can be used to store semantically-sound
	// clues about this Build (e.g. to identify the underlying swarming task so
	// that we don't need to RPC back to the build source to find that out). This
	// can also be used for link generation in the UI, since the schema for these
	// URIs should be stable within Milo (so if swarming changes its URL format we
	// can change the links in the UI code without map-reducing these
	// ContextURIs).
	ContextURI []string

	// The buildbucket buildsets associated with this Build, if any.
	//
	// Example:
	//   commit/gitiles/<host>/<project/path>/+/<commit>
	//
	// See https://chromium.googlesource.com/infra/infra/+/master/appengine/cr-buildbucket/doc/index.md#buildset-tag
	BuildSet []string

	// Created is the time when the Build was first created. Due to pending
	// queues, this may be substantially before Summary.Start.
	Created time.Time

	// Summary summarizes relevant bits about the overall build.
	Summary Summary

	// Manifests is a list of links to source manifests that this build reported.
	Manifests []ManifestLink

	// ManifestKeys is the list of ManifestKey entries for this BuildSummary.
	ManifestKeys []ManifestKey

	// AnnotationURL is the URL to the logdog annotation location. This will be in
	// the form of:
	//   logdog://service.host.example.com/project_id/prefix/+/stream/name
	// (Deprecated)
	AnnotationURL string

	// Version can be used by buildsource implementations to compare with an
	// externally provided version number/timestamp to ensure that BuildSummary
	// objects are only updated forwards in time.
	//
	// Known uses:
	//   * Buildbucket populates this with Build.UpdatedTs, which is guaranteed to
	//     be monotonically increasing. Used to ignore out-of-order pubsub
	//     messages.
	Version int64

	// Experimental indicates that even though this build belongs to the indicated
	// Builder, it's considered experimental (e.g. "not in production"). The meaning
	// of this varies by builder, but generally it indicates that this build did
	// not write to production services and/or was not running the production
	// version of this Builder's job definition (e.g. a modified not-committed
	// recipe).
	Experimental bool

	// If NO, then the build status SHOULD NOT be used to assess correctness of
	// the input gitiles_commit or gerrit_changes.
	// For example, if a pre-submit build has failed, CQ MAY still land the CL.
	// For example, if a post-submit build has failed, CLs MAY continue landing.
	Critical buildbucketpb.Trinary
	// contains filtered or unexported fields
}

BuildSummary is a datastore model which is used for storing staandardized summarized build data, and is used for backend-agnostic views (i.e. builders, console). It contains only data that:

  • is necessary to render these simplified views
  • is present in all implementations (buildbot, buildbucket)

This entity will live as a child of the various implementation's representations of a build (e.g. buildbotBuild). It has various 'tag' fields so that it can be queried by the various backend-agnostic views.

func (*BuildSummary) AddManifestKey 

func (bs *BuildSummary) AddManifestKey(project, console, manifest, repoURL string, revision []byte)

AddManifestKey adds a new entry to ManifestKey.

`revision` should be the hex-decoded git revision.

It's up to the caller to ensure that entries in ManifestKey aren't duplicated.

func (*BuildSummary) AddManifestKeysFromBuildSets 

func (bs *BuildSummary) AddManifestKeysFromBuildSets(c context.Context) error

AddManifestKeysFromBuildSets potentially adds one or more ManifestKey's to the BuildSummary for any defined BuildSets.

This assumes that bs.BuilderID and bs.BuildSet have already been populated. If BuilderID is not populated, this will return an error.

func (*BuildSummary) GetBuildName 

func (bs *BuildSummary) GetBuildName() string

GetBuildName returns an abridged version of the BuildID meant for human consumption. Currently, this is always the last token of the BuildID.

func (*BuildSummary) GetConsoleNames 

func (bs *BuildSummary) GetConsoleNames() ([]string, error)

GetConsoleNames extracts the "<project>/<console>" names from the BuildSummary's current ManifestKeys.

func (*BuildSummary) GitilesCommit 

func (bs *BuildSummary) GitilesCommit() *buildbucketpb.GitilesCommit

GitilesCommit extracts the first BuildSet which is a valid GitilesCommit.

If no such BuildSet is found, this returns nil.

func (*BuildSummary) PreviousByGitilesCommit 

func (bs *BuildSummary) PreviousByGitilesCommit(c context.Context) (builds []*BuildSummary, commits []*gitpb.Commit, err error)

PreviousByGitilesCommit returns the previous build(s) (and all intervening commits) based on the GitilesCommit BuildSet of the given build.

There may be multiple BuildSummaries, if there were rebuilds. The resulting BuildSummaries will be sorted in reverse creation order, so that builds[0] is always the most-recently-created build.

This will only look up to 100 commits into the past.

If this is unable to find the previous build, it returns ErrUnknownPreviousBuild. 

func (bs *BuildSummary) SelfLink() string

SelfLink returns a link to the build represented by the BuildSummary via BuildID.

BuildID is used for indexing BuildSummary and BuilderSummary entities, so this lets us get links given BuildSummaries and BuilderSummaries in the console, console header, and console lists.

Returns bogus URL in case of error (just "/" + BuildID). Depends on buildbucket.ParseBuildAddress to get project Depends on frontend/routes.go for link structures.

Buildbot: "buildbot/<mastername>/<buildername>/<buildnumber>" Buildbucket: "buildbucket/<buildaddr>" For buildbucket, <buildaddr> looks like <bucketname>/<buildername>/<buildnumber> if available and <buildid> otherwise.

type BuilderPool 

type BuilderPool struct {

	// BuilderID is a datastore key pointing to the parent BuilderSummary entity.
	BuilderID *datastore.Key `gae:"$parent"`

	// PoolKey is a datastore key pointing to the BotPool associated with this Builder.
	PoolKey *datastore.Key
	// contains filtered or unexported fields
}

BuilderPool is a datastore entity that associates a BuilderSummary entity with a BotPool entity. BuilderPool is a separate entity from BuilderSummary to allow for transaction-less updates.

type BuilderSummary 

type BuilderSummary struct {
	// BuilderID is the global identifier for the builder that this Build belongs to, i.e.:
	//   "buildbot/<mastername>/<buildername>"
	//   "buildbucket/<bucketname>/<buildername>"
	// Matches field in BuildSummary.
	BuilderID string `gae:"$id"`

	// The LUCI project ID associated with this build. This is used for generating links.
	ProjectID string

	// LastFinishedCreated is the time the last finished build was created.
	LastFinishedCreated time.Time

	// LastFinishedStatus is the status of last finished build on builder.
	LastFinishedStatus Status

	// LastFinishedBuildID is the BuildID of the BuildSummary associated with last finished build on
	// the builder.
	LastFinishedBuildID string

	// LastFinishedExperimental indicates if the last build on this builder was
	// marked as experimental.
	LastFinishedExperimental bool
	// contains filtered or unexported fields
}

BuilderSummary holds builder state for the purpose of representing e.g. header consoles. 

func (b *BuilderSummary) LastFinishedBuildIDLink() string

LastFinishedBuildIDLink returns a link to the last finished build. 

func (b *BuilderSummary) SelfLink() string

SelfLink returns a link to the associated builder. 

type Link struct {
	// Title (text) of the link.
	Label string

	// The destination for the link.
	URL string
}

Link denotes a single labeled link.

type ManifestKey 

type ManifestKey []byte

ManifestKey is an index entry for BuildSummary, which looks like 

0 ++ project ++ console ++ manifest_name ++ url ++ revision.decode('hex')

This is used to index this BuildSummary as the row for any consoles that it shows up in that use the Manifest/RepoURL/Revision indexing scheme.

(++ is cmpbin concatenation)

Example: 

0 ++ "chromium" ++ "main" ++ "UNPATCHED" ++ "https://.../src.git" ++ deadbeef

The list of interested consoles is compiled at build summarization time. 

type ManifestLink struct {
	// The name of the manifest as the build annotated it.
	Name string

	// The manifest ID (sha256).
	ID []byte
}

ManifestLink is an in-MILO link to a named source manifest.

func (*ManifestLink) FromProperty 

func (m *ManifestLink) FromProperty(p ds.Property) (err error)

FromProperty implements ds.PropertyConverter

func (*ManifestLink) ToProperty 

func (m *ManifestLink) ToProperty() (ds.Property, error)

ToProperty implements ds.PropertyConverter

type PartialManifestKey 

type PartialManifestKey []byte

PartialManifestKey is an incomplete ManifestKey key which can be made complete by calling AddRevision.

func NewPartialManifestKey 

func NewPartialManifestKey(project, console, manifest, repoURL string) PartialManifestKey

NewPartialManifestKey generates a ManifestKey prefix corresponding to the given parameters.

func (PartialManifestKey) AddRevision 

func (p PartialManifestKey) AddRevision(revision []byte) ManifestKey

AddRevision appends a git revision (as bytes) to the PartialManifestKey, returning a full index value for BuildSummary.ManifestKey.

type PatchInfo 

type PatchInfo struct {
	// A link to the patch page (i.e. the gerrit/rietveld review page).
	Link Link

	// The email of the author of the Patch.
	AuthorEmail string
}

PatchInfo provides information about a patch included in a build.

type PoolDescriptor 

type PoolDescriptor []string

PoolDescriptor describes the attributes of a pool in "tag:value" format. This is defined as Swarming Dimensions + Hostname.

func NewPoolDescriptor 

func NewPoolDescriptor(host string, dimensions []string) PoolDescriptor

NewPoolDescriptor creates a new PoolDescriptor given a swarming hostname and a slice of dimensions. The dimensions are expected to be in "key:value" format, where the key is the tag name. This is the same format returned by the Swarming API.

func (PoolDescriptor) Dimensions 

func (d PoolDescriptor) Dimensions() strpair.Map

Dimensions returns a copy of the PoolDescriptor without the swarming_hostname item in strpair.Map format.

func (PoolDescriptor) Host 

func (d PoolDescriptor) Host() string

Host returns the swarming_hostname item of the PoolDescriptor.

func (PoolDescriptor) PoolID 

func (d PoolDescriptor) PoolID() string

PoolID returns they ID for a BotPool with the specified PoolDescriptor. The ID is a SHA256 hash in hex form. descriptor must be pre-sorted (I.E. Created with NewPoolDescriptor).

type Status 

type Status int

Status indicates the status of some piece of the CI; builds, steps, builders, etc. The UI maps this to a color, and some statuses may map to the same color; however, we attempt to preserve full informational fidelity. 

const (
	// NotRun if the component has not yet been run.  E.g. if the component has
	// been scheduled, but is pending execution.
	NotRun Status = iota

	// Running if the component is currently running.
	Running

	// Success if the component has finished executing and accomplished what it
	// was supposed to.
	Success

	// Failure if the component has finished executing and failed in
	// a non-exceptional way. e.g. if a test completed execution, but determined
	// that the code was bad.
	Failure

	// Warning if the component has finished executing, but encountered
	// non-stoppage problems. e.g. if a test completed execution, but determined
	// that the code was slow (but not slow enough to be a failure).
	Warning

	// InfraFailure if the component has finished incompletely due to an
	// infrastructure layer.
	//
	// This is used to categorize all unknown errors.
	InfraFailure

	// Exception if the component has finished incompletely due to an exceptional
	// error in the task. That means the infrastructure layers executed the task
	// completely, but the task self-reported that it failed in an exceptional
	// way.
	//
	// DON'T USE THIS IN ANY NEW CODE. Instead, prefer InfraFailure.
	Exception

	// Expired if the component was never scheduled due to resource exhaustion.
	Expired

	// Cancelled if the component had external intervention to stop it after it
	// was scheduled, but before it completed on its own.
	Cancelled
)

func (Status) MarshalJSON 

func (s Status) MarshalJSON() ([]byte, error)

MarshalJSON renders enums into String rather than an int when marshalling.

func (Status) String 

func (i Status) String() string

func (Status) Terminal 

func (s Status) Terminal() bool

Terminal returns true if the step status won't change.

type Summary 

type Summary struct {
	// Status indicates the 'goodness' and lifetime of the thing. This usually
	// translates directly to a status color.
	Status Status

	// Start indicates when this thing started doing its action.
	Start time.Time

	// End indicates when this thing completed doing its action.
	End time.Time

	// Text is a possibly-multi-line summary of what happened.
	Text []string
}

Summary summarizes a thing (step, build, group of builds, whatever).
