Functions

func DispatchChangeLogsByPeriod

func DispatchChangeLogsByPeriod(pruningPeriods []*pruningPeriod, changesChan chan *tree.ChangeLog, doneChan chan bool) ([]*pruningPeriod, error)

DispatchChangeLogsByPeriod places each change in its corresponding period

func ParseDuration

func ParseDuration(duration string) (d time.Duration, e error)

ParseDuration is similar to time.ParseDuration, with specific case for "d" suffix on duration.

func PreparePeriods

func PreparePeriods(startTime time.Time, periods []*tree.VersioningKeepPeriod) ([]*pruningPeriod, error)

PreparePeriods computes the actual periods from definitions.

func PruneAllWithMaxSize

func PruneAllWithMaxSize(periods []*pruningPeriod, maxSize int64) (toBeRemoved []*tree.ChangeLog, remaining []*tree.ChangeLog)

PruneAllWithMaxSize checks overall size and removes older versions. It should be called after pruning by periods.

Types

type BoltStore

type BoltStore struct {

	// For Testing purpose : delete file after closing
	DeleteOnClose bool
	// Path to the DB file
	DbPath string
	// contains filtered or unexported fields
}

func NewBoltStore

func NewBoltStore(fileName string, deleteOnClose ...bool) (*BoltStore, error)

func (*BoltStore) Close

func (b *BoltStore) Close() error

func (*BoltStore) DeleteVersionsForNode

func (b *BoltStore) DeleteVersionsForNode(nodeUuid string, versions ...*tree.ChangeLog) error

DeleteVersionsForNode deletes whole node bucket at once.

func (*BoltStore) GetLastVersion

func (b *BoltStore) GetLastVersion(nodeUuid string) (log *tree.ChangeLog, err error)

GetLastVersion retrieves the last version registered for this node.

func (*BoltStore) GetVersion

func (b *BoltStore) GetVersion(nodeUuid string, versionId string) (*tree.ChangeLog, error)

GetVersion retrieves a specific version from the node bucket.

func (*BoltStore) GetVersions

func (b *BoltStore) GetVersions(nodeUuid string) (chan *tree.ChangeLog, chan bool)

GetVersions returns all versions from the node bucket, in reverse order (last inserted first).

func (*BoltStore) ListAllVersionedNodesUuids

func (b *BoltStore) ListAllVersionedNodesUuids() (chan string, chan bool, chan error)

ListAllVersionedNodesUuids lists all nodes uuids

func (*BoltStore) StoreVersion

func (b *BoltStore) StoreVersion(nodeUuid string, log *tree.ChangeLog) error

StoreVersion stores a version in the node bucket.

type DAO

type DAO interface {
	GetLastVersion(nodeUuid string) (*tree.ChangeLog, error)
	GetVersions(nodeUuid string) (chan *tree.ChangeLog, chan bool)
	GetVersion(nodeUuid string, versionId string) (*tree.ChangeLog, error)
	StoreVersion(nodeUuid string, log *tree.ChangeLog) error
	DeleteVersionsForNode(nodeUuid string, versions ...*tree.ChangeLog) error
	ListAllVersionedNodesUuids() (chan string, chan bool, chan error)
}

type PruneVersionsAction

type PruneVersionsAction struct {
	Handler views.Handler
	Pool    *views.ClientsPool
}

func (*PruneVersionsAction) GetName

func (c *PruneVersionsAction) GetName() string

GetName returns the Unique identifier.

func (*PruneVersionsAction) Init

func (c *PruneVersionsAction) Init(job *jobs.Job, cl client.Client, action *jobs.Action) error

Init passes the parameters to a newly created PruneVersionsAction.

func (*PruneVersionsAction) Run

func (c *PruneVersionsAction) Run(ctx context.Context, channels *actions.RunnableChannels, input jobs.ActionMessage) (jobs.ActionMessage, error)

Run processes the actual action code.

type VersionAction

type VersionAction struct {
	Handler views.Handler
	Pool    *views.ClientsPool
}

func (*VersionAction) GetName

func (c *VersionAction) GetName() string

GetName returns the Unique identifier for this VersionAction

func (*VersionAction) Init

func (c *VersionAction) Init(job *jobs.Job, cl client.Client, action *jobs.Action) error

Init sets this VersionAction parameters.

func (*VersionAction) Run

func (c *VersionAction) Run(ctx context.Context, channels *actions.RunnableChannels, input jobs.ActionMessage) (jobs.ActionMessage, error)

Run processes the actual action code
