Functions

func BuildCanonicalPath 

func BuildCanonicalPath(pathType PathType, paths ...string) string

BuildCanonicalPath returns a canonical path for a path components. This a canonical path and may need to be converted to a platform specific path, for example, on Windows, this might correspond to k:\private\username. Note that "canonical" here indicates it's in the form of /keybase/<tlfType>/blah... . It does not try to canonicalize TLF names.

func BuildCanonicalPathForTlf 

func BuildCanonicalPathForTlf(tlf tlf.ID, paths ...string) string

BuildCanonicalPathForTlf returns a canonical path for a tlf. Although tlf identifies a TLF, paths should still include the TLF name. This function does not try to canonicalize TLF names.

func BuildCanonicalPathForTlfName 

func BuildCanonicalPathForTlfName(t tlf.Type, tlfName tlf.CanonicalName) string

BuildCanonicalPathForTlfName returns a canonical path for a tlf.

func BuildCanonicalPathForTlfType 

func BuildCanonicalPathForTlfType(t tlf.Type, paths ...string) string

BuildCanonicalPathForTlfType is like BuildCanonicalPath, but accepts a tlf.Type instead of PathType.

func BuildProtocolPathForTlfName 

func BuildProtocolPathForTlfName(
	t tlf.Type, tlfName tlf.CanonicalName) keybase1.Path

BuildProtocolPathForTlfName builds a `keybase1.Path` for the given TLF type and name.

func CheckHandleOffline 

func CheckHandleOffline(
	ctx context.Context, name string, t tlf.Type) error

CheckHandleOffline does light checks whether a TLF handle looks ok, it avoids all network calls.

func IdentifyHandle 

func IdentifyHandle(
	ctx context.Context, nug idutil.NormalizedUsernameGetter,
	identifier idutil.Identifier, osg idutil.OfflineStatusGetter,
	h *Handle) error

IdentifyHandle identifies the canonical names in the given handle.

func IdentifySingleAssertion 

func IdentifySingleAssertion(
	ctx context.Context, assertion, reason string, identifier idutil.Identifier,
	offline keybase1.OfflineAvailability) (
	name kbname.NormalizedUsername, err error)

IdentifySingleAssertion identifies a single assertion, and takes care of any necessary extended identify behaviors. It does not relay any broken identify warnings back to the caller, however.

func IdentifyUserList 

func IdentifyUserList(ctx context.Context, nug idutil.NormalizedUsernameGetter,
	identifier idutil.Identifier, ids []keybase1.UserOrTeamID, t tlf.Type,
	offline keybase1.OfflineAvailability) error

IdentifyUserList identifies the users in the given list. Only use this when the usernames are not known - like when rekeying.

func MakeExtendedIdentify 

func MakeExtendedIdentify(ctx context.Context,
	behavior keybase1.TLFIdentifyBehavior) (context.Context, error)

MakeExtendedIdentify populates a context with an ExtendedIdentify directive.

func NewReadAccessError 

func NewReadAccessError(h *Handle, username kbname.NormalizedUsername, filename string) error

NewReadAccessError constructs a ReadAccessError for the given directory and user.

func NewWriteAccessError 

func NewWriteAccessError(h *Handle, username kbname.NormalizedUsername, filename string) error

NewWriteAccessError is an access error trying to write a file

Types

type ConstIDGetter 

type ConstIDGetter struct {
	ID tlf.ID
}

ConstIDGetter is an IDGetter that always returns the same TLF ID.

func (ConstIDGetter) GetIDForHandle 

func (c ConstIDGetter) GetIDForHandle(_ context.Context, _ *Handle) (
	tlf.ID, error)

GetIDForHandle implements the IDGetter interface for ConstIDGetter.

func (ConstIDGetter) ValidateLatestHandleNotFinal 

func (c ConstIDGetter) ValidateLatestHandleNotFinal(
	_ context.Context, _ *Handle) (bool, error)

ValidateLatestHandleNotFinal implements the IDGetter interface for ConstIDGetter.

type ExtendedIdentify 

type ExtendedIdentify struct {
	Behavior keybase1.TLFIdentifyBehavior
	// contains filtered or unexported fields
}

ExtendedIdentify is a struct to track the behavior and results of an identify.

func GetExtendedIdentify 

func GetExtendedIdentify(ctx context.Context) (ei *ExtendedIdentify)

GetExtendedIdentify returns the extended identify info associated with the given context.

func (*ExtendedIdentify) GetTlfBreakAndClose 

func (ei *ExtendedIdentify) GetTlfBreakAndClose() keybase1.TLFBreak

GetTlfBreakAndClose returns a keybase1.TLFBreak. This should only be called for behavior.WarningInsteadOfErrorOnBrokenTracks() == true, and after makeTlfBreaksIfNeeded is called, to make sure user proof breaks get populated in GUI mode.

If called otherwise, we don't panic here anymore, since we can't panic on nil ei.tlfBreaks. The reason is if a previous successful identify has already happened recently, it could cause this identify to be skipped, which means ei.tlfBreaks is never populated. In this case, it's safe to return an empty keybase1.TLFBreak.

func (*ExtendedIdentify) OnError 

func (ei *ExtendedIdentify) OnError(ctx context.Context)

OnError is called when the identify process has encountered a hard error.

func (*ExtendedIdentify) TeamBreak 

func (ei *ExtendedIdentify) TeamBreak(
	ctx context.Context, teamID keybase1.TeamID,
	breaks *keybase1.IdentifyTrackBreaks)

TeamBreak should be called when an identify call for a team has completed, and may (or may not) contain breaks.

func (*ExtendedIdentify) UserBreak 

func (ei *ExtendedIdentify) UserBreak(
	ctx context.Context, username kbname.NormalizedUsername, uid keybase1.UID,
	breaks *keybase1.IdentifyTrackBreaks)

UserBreak should be called when an identify call for a user has completed, and may (or may not) contain breaks.

type ExtendedIdentifyAlreadyExists 

type ExtendedIdentifyAlreadyExists struct{}

ExtendedIdentifyAlreadyExists is returned when MakeExtendedIdentify is called on a context already with ExtendedIdentify.

func (ExtendedIdentifyAlreadyExists) Error 

func (e ExtendedIdentifyAlreadyExists) Error() string

type Handle 

type Handle struct {
	// contains filtered or unexported fields
}

Handle contains all the info in a tlf.Handle as well as additional info. This doesn't embed tlf.Handle to avoid having to keep track of data in multiple places.

func MakeHandle 

func MakeHandle(
	ctx context.Context, bareHandle tlf.Handle, t tlf.Type,
	resolver idutil.Resolver, nug idutil.NormalizedUsernameGetter,
	idGetter IDGetter, offline keybase1.OfflineAvailability) (
	*Handle, error)

MakeHandle creates a Handle from the given tlf.Handle and the given NormalizedUsernameGetter (which is usually a KBPKI). `t` is the `tlf.Type` of the new handle. (Note this could be different from `bareHandle.Type()`, if this is an implicit team TLF.)

func MakeHandleWithTlfID 

func MakeHandleWithTlfID(
	ctx context.Context, bareHandle tlf.Handle, t tlf.Type,
	resolver idutil.Resolver, nug idutil.NormalizedUsernameGetter,
	tlfID tlf.ID, offline keybase1.OfflineAvailability) (
	*Handle, error)

MakeHandleWithTlfID is like `MakeHandle`, but it ensures the handle's TLF ID is always set to `tlfID`, even if it corresponds to an implicit team for which the iteam settings don't yet contain a TLF ID (due to a cross-device race or certain testing scenarios).

func NewHandle 

func NewHandle(
	ty tlf.Type,
	resolvedWriters map[keybase1.UserOrTeamID]kbname.NormalizedUsername,
	unresolvedWriters, unresolvedReaders []keybase1.SocialAssertion,
	name tlf.CanonicalName, tlfID tlf.ID) *Handle

NewHandle returns a simple new Handle based on the given fields. This is probably most useful for testing.

func ParseHandle 

func ParseHandle(
	ctx context.Context, kbpki idutil.KBPKI, idGetter IDGetter,
	osg idutil.OfflineStatusGetter, name string, t tlf.Type) (
	*Handle, error)

ParseHandle parses a Handle from an encoded string. See Handle.GetCanonicalName() for the opposite direction.

Some errors that may be returned and can be specially handled:

idutil.TlfNameNotCanonical: Returned when the given name is not canonical -- another name to try (which itself may not be canonical) is in the error. Usually, you want to treat this as a symlink to the name to try.

idutil.NoSuchNameError: Returned when public is set and the given folder has no public folder.

TODO In future perhaps all code should switch over to preferred handles, and rename TlfNameNotCanonical to TlfNameNotPreferred.

func ParseHandlePreferred 

func ParseHandlePreferred(
	ctx context.Context, kbpki idutil.KBPKI, idGetter IDGetter,
	osg idutil.OfflineStatusGetter, name string, t tlf.Type) (
	*Handle, error)

ParseHandlePreferred returns idutil.TlfNameNotCanonical if not in the preferred format. Preferred format means that the users own username (from kbpki) as a writer is put before other usernames in the tlf name. i.e. Canon Preferred myname,other myname,other another,myname myname,another This function also can return idutil.NoSuchNameError or idutil.TlfNameNotCanonical. idutil.TlfNameNotCanonical is returned from this function when the name is not the *preferred* name.

func ParseHandlePreferredQuick 

func ParseHandlePreferredQuick(
	ctx context.Context, kbpki idutil.KBPKI, osg idutil.OfflineStatusGetter,
	name string, ty tlf.Type) (handle *Handle, err error)

ParseHandlePreferredQuick parses a handle from a name, without doing this time consuming checks needed for implicit-team checking or TLF-ID-fetching.
