Functions

func FilterPackageIDs

func FilterPackageIDs(m map[string]*PkPackageIDActionData, packages []string) ([]string, error)

FilterPackageIDs returns a list of packageIDs which match the set of package names in packages.

func FilterPackageState

func FilterPackageState(m map[string]*PkPackageIDActionData, packages []string, state string) (result []string, err error)

FilterPackageState returns all packages that are in package and match the specific state.

func FilterState

func FilterState(m map[string]*PkPackageIDActionData, packages []string, state string) (result map[string]bool, err error)

FilterState returns a map of whether each package queried matches the particular state.

func FlagInData

func FlagInData(flag, data string) bool

FlagInData asks whether a flag exists inside the data portion of a packageID field?

func FmtTransactionMethod

func FmtTransactionMethod(method string) string

FmtTransactionMethod builds the transaction method string properly.

func IsMyArch

func IsMyArch(arch string) (bool, error)

IsMyArch determines if a PackageKit architecture matches the current os arch.

Types

type Conn

type Conn struct {
	Debug bool
	Logf  func(format string, v ...interface{})
	// contains filtered or unexported fields
}

Conn is a wrapper struct so we can pass bus connection around in the struct.

func NewBus

func NewBus() *Conn

NewBus returns a new bus connection.

func (*Conn) Close

func (obj *Conn) Close() error

Close closes the dbus connection object.

func (*Conn) CreateTransaction

func (obj *Conn) CreateTransaction() (dbus.ObjectPath, error)

CreateTransaction creates and returns a transaction path.

func (*Conn) GetBus

func (obj *Conn) GetBus() *dbus.Conn

GetBus gets the dbus connection object.

func (*Conn) GetFilesByPackageID

func (obj *Conn) GetFilesByPackageID(packageIDs []string) (files map[string][]string, err error)

GetFilesByPackageID gets the list of files that are contained inside a list of packageIDs.

func (*Conn) GetUpdates

func (obj *Conn) GetUpdates(filter uint64) ([]string, error)

GetUpdates gets a list of packages that are installed and which can be updated, mod filter.

func (*Conn) InstallPackages

func (obj *Conn) InstallPackages(packageIDs []string, transactionFlags uint64) error

InstallPackages installs a list of packages by packageID.

func (*Conn) IsInstalled

func (obj *Conn) IsInstalled(pkg string) (bool, error)

IsInstalled returns if a package is installed. TODO: this could be optimized by making the resolve call directly

func (*Conn) IsInstalledList

func (obj *Conn) IsInstalledList(packages []string) ([]bool, error)

IsInstalledList queries a list of packages to see if they are installed.

func (*Conn) PackagesToPackageIDs

func (obj *Conn) PackagesToPackageIDs(packageMap map[string]string, filter uint64) (map[string]*PkPackageIDActionData, error)

PackagesToPackageIDs is a helper function that *might* be generally useful outside mgmt. The packageMap input has the package names as keys and requested states as values. These states can be: installed, uninstalled, newest or a requested version str.

func (*Conn) RemovePackages

func (obj *Conn) RemovePackages(packageIDs []string, transactionFlags uint64) error

RemovePackages removes a list of packages by packageID.

func (*Conn) ResolvePackages

func (obj *Conn) ResolvePackages(packages []string, filter uint64) ([]string, error)

ResolvePackages runs the PackageKit Resolve method and returns the result.

func (*Conn) UpdatePackages

func (obj *Conn) UpdatePackages(packageIDs []string, transactionFlags uint64) error

UpdatePackages updates a list of packages to versions that are specified.

func (*Conn) WatchChanges

func (obj *Conn) WatchChanges() (chan *dbus.Signal, error)

WatchChanges gets a signal anytime an event happens.

type PkPackageIDActionData

type PkPackageIDActionData struct {
	Found     bool
	Installed bool
	Version   string
	PackageID string
	Newest    bool
}

PkPackageIDActionData is a struct that is returned by PackagesToPackageIDs in the map values.
