Functions

func MatchUnitPatterns

func MatchUnitPatterns(patterns []string, units []dbus.UnitStatus) ([]dbus.UnitStatus, error)

MatchUnitPatterns returns a list of units that match the pattern list. This algo, including filepath.Match, is designed to (somewhat) emulate the behavior of ListUnitsByPatterns, which uses `fnmatch`.

Types

type UnitFetcher

type UnitFetcher func(ctx context.Context, conn *dbus.Conn, states, patterns []string) ([]dbus.UnitStatus, error)

UnitFetcher a unit retrieval method

func InstrospectForUnitMethods

func InstrospectForUnitMethods(conn *dbusRaw.Conn) (UnitFetcher, error)

InstrospectForUnitMethods determines what methods are available via dbus for listing systemd units. We have a number of functions, some better than others, for getting and filtering unit lists. This will attempt to find the most optimal method, and move down to methods that require more work.
