Functions

func ParseMailmap

func ParseMailmap(contents string) map[string]object.Signature

ParseMailmap parses the contents of .mailmap and returns the mapping between signature parts. It does *not* follow the full signature matching convention, that is, developers are identified by email and by name independently.

Types

type Detector

type Detector struct {
	core.NoopMerger
	// PeopleDict maps email || name  -> developer id
	PeopleDict map[string]int
	// ReversedPeopleDict maps developer id -> description
	ReversedPeopleDict []string
}

Detector determines the author of a commit. Same person can commit under different signatures, and we apply some heuristics to merge those together. It is a PipelineItem.

func (*Detector) Configure

func (detector *Detector) Configure(facts map[string]interface{}) error

Configure sets the properties previously published by ListConfigurationOptions().

func (*Detector) Consume

func (detector *Detector) Consume(deps map[string]interface{}) (map[string]interface{}, error)

Consume runs this PipelineItem on the next commit data. `deps` contain all the results from upstream PipelineItem-s as requested by Requires(). Additionally, DependencyCommit is always present there and represents the analysed *object.Commit. This function returns the mapping with analysis results. The keys must be the same as in Provides(). If there was an error, nil is returned.

func (*Detector) Fork

func (detector *Detector) Fork(n int) []core.PipelineItem

Fork clones this PipelineItem.

func (*Detector) GeneratePeopleDict

func (detector *Detector) GeneratePeopleDict(commits []*object.Commit)

GeneratePeopleDict loads author signatures from the specified list of Git commits.

func (*Detector) Initialize

func (detector *Detector) Initialize(repository *git.Repository) error

Initialize resets the temporary caches and prepares this PipelineItem for a series of Consume() calls. The repository which is going to be analysed is supplied as an argument.

func (*Detector) ListConfigurationOptions

func (detector *Detector) ListConfigurationOptions() []core.ConfigurationOption

ListConfigurationOptions returns the list of changeable public properties of this PipelineItem.

func (*Detector) LoadPeopleDict

func (detector *Detector) LoadPeopleDict(path string) error

LoadPeopleDict loads author signatures from a text file. The format is one signature per line, and the signature consists of several keys separated by "|". The first key is the main one and used to reference all the rest.

func (Detector) MergeReversedDicts

func (detector Detector) MergeReversedDicts(rd1, rd2 []string) (map[string][3]int, []string)

MergeReversedDicts joins two identity lists together, excluding duplicates, in-order.

func (*Detector) Name

func (detector *Detector) Name() string

Name of this PipelineItem. Uniquely identifies the type, used for mapping keys, etc.

func (*Detector) Provides

func (detector *Detector) Provides() []string

Provides returns the list of names of entities which are produced by this PipelineItem. Each produced entity will be inserted into `deps` of dependent Consume()-s according to this list. Also used by core.Registry to build the global map of providers.

func (*Detector) Requires

func (detector *Detector) Requires() []string

Requires returns the list of names of entities which are needed by this PipelineItem. Each requested entity will be inserted into `deps` of Consume(). In turn, those entities are Provides() upstream.
