            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.


                type Bot

                type Bot struct {

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

                    type BotStatus int

                      BotStatus indicates the status of a machine.

                        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 (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.

                                      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.

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.
