Functions

func AppendPlainToOpaque

func AppendPlainToOpaque(o *types.Opaque, key, value string) *types.Opaque

AppendPlainToOpaque adds a new key value pair as a plain string on the given opaque and returns it

func ExistsInOpaque

func ExistsInOpaque(o *types.Opaque, key string) bool

ExistsInOpaque returns true if the key exists in the opaque (ignoring the value)

func ExtractGranteeID

func ExtractGranteeID(grantee *provider.Grantee) (*userpb.UserId, *grouppb.GroupId)

ExtractGranteeID returns the ID, user or group, set in the GranteeId object

func GetClientIP

func GetClientIP(r *http.Request) (string, error)

GetClientIP retrieves the client IP from incoming requests

func GetLDAPClientForAuth

func GetLDAPClientForAuth(c *LDAPConn) (ldap.Client, error)

GetLDAPClientForAuth initializes an LDAP connection. The connection is not authenticated when returned. The main purpose for GetLDAPClientForAuth is to get and LDAP connection that can be used to issue a single bind request to authenticate a user.

func GetLDAPClientWithReconnect

func GetLDAPClientWithReconnect(c *LDAPConn) (ldap.Client, error)

GetLDAPClientWithReconnect initializes a long-lived LDAP connection that automatically reconnects on connection errors. It allows to set TLS options e.g. to add trusted Certificates or disable Certificate verification

func GetViewMode

func GetViewMode(viewMode string) gateway.OpenInAppRequest_ViewMode

GetViewMode converts a human-readable string to a view mode for opening a resource in an app.

func GranteeEqual

func GranteeEqual(u, v *provider.Grantee) bool

GranteeEqual returns whether two grantees have the same field values.

func GroupEqual

func GroupEqual(u, v *grouppb.GroupId) bool

GroupEqual returns whether two groups have the same field values.

func IsAbsolutePathReference

func IsAbsolutePathReference(ref *provider.Reference) bool

IsAbsolutePathReference returns true if the given reference qualifies as a global path when only the path is set and starts with /

func IsAbsoluteReference

func IsAbsoluteReference(ref *provider.Reference) bool

IsAbsoluteReference returns true if the given reference qualifies as absolute when either only the resource id is set or only the path is set and starts with /

TODO(corby): Currently if the path is empty, the ResourceId is set but has empty storageId and OpaqueId then the reference is still being viewed as absolute. We need to check if we want that because in some places we might not want to set both StorageId and OpaqueId so we can't do a hard check if they are set.

func IsEmailValid

func IsEmailValid(e string) bool

IsEmailValid checks whether the provided email has a valid format.

func IsRelativeReference

func IsRelativeReference(ref *provider.Reference) bool

IsRelativeReference returns true if the given reference qualifies as relative when the resource id is set and the path starts with a .

TODO(corby): Currently if the path begins with a dot, the ResourceId is set but has empty storageId and OpaqueId then the reference is still being viewed as relative. We need to check if we want that because in some places we might not want to set both StorageId and OpaqueId so we can't do a hard check if they are set.

func IsValidName

func IsValidName(name string) bool

IsValidName cheks if the given name doesn't contain any non-alpha, space or dash characters.

func IsValidPhoneNumber

func IsValidPhoneNumber(number string) bool

IsValidPhoneNumber checks whether the provided phone number has a valid format.

func IsValidWebAddress

func IsValidWebAddress(address string) bool

IsValidWebAddress checks whether the provided address is a valid URL.

func LaterTS

func LaterTS(t1 *types.Timestamp, t2 *types.Timestamp) *types.Timestamp

LaterTS returns the timestamp which occurs later.

func MakeRelativePath

func MakeRelativePath(p string) string

MakeRelativePath prefixes the path with a . to use it in a relative reference

func MarshalProtoV1ToJSON

func MarshalProtoV1ToJSON(m proto.Message) ([]byte, error)

MarshalProtoV1ToJSON marshals a proto V1 message to a JSON byte array TODO: update this once we start using V2 in CS3APIs

func RandString

func RandString(n int) string

RandString is a helper to create tokens.

func ReadPlainFromOpaque

func ReadPlainFromOpaque(o *types.Opaque, key string) string

ReadPlainFromOpaque reads a plain string from the given opaque map

func ResolvePath

func ResolvePath(path string) (string, error)

ResolvePath converts relative local paths to absolute paths

func ResourceEqual

func ResourceEqual(u, v *provider.Reference) bool

ResourceEqual returns whether two resources have the same field values.

func ResourceIDEqual

func ResourceIDEqual(u, v *provider.ResourceId) bool

ResourceIDEqual returns whether two resources have the same field values.

func Skip

func Skip(source string, prefixes []string) bool

Skip evaluates whether a source endpoint contains any of the prefixes. i.e: /a/b/c/d/e contains prefix /a/b/c

func TSNow

func TSNow() *types.Timestamp

TSNow returns the current UTC timestamp

func TSToTime

func TSToTime(ts *types.Timestamp) time.Time

TSToTime converts a protobuf Timestamp to Go's time.Time.

func TSToUnixNano

func TSToUnixNano(ts *types.Timestamp) uint64

TSToUnixNano converts a protobuf Timestamp to uint64 with nanoseconds resolution.

func ToSnakeCase

func ToSnakeCase(str string) string

ToSnakeCase converts a CamelCase string to a snake_case string.

func UnmarshalJSONToProtoV1

func UnmarshalJSONToProtoV1(b []byte, m proto.Message) error

UnmarshalJSONToProtoV1 decodes a JSON byte array to a specified proto message type TODO: update this once we start using V2 in CS3APIs

func UserEqual

func UserEqual(u, v *userpb.UserId) bool

UserEqual returns whether two users have the same field values.

func UserTypeMap

func UserTypeMap(accountType string) userpb.UserType

UserTypeMap translates account type string to CS3 UserType

func UserTypeToString

func UserTypeToString(accountType userpb.UserType) string

Types

type LDAPConn

type LDAPConn struct {
	URI          string `mapstructure:"uri"`
	Insecure     bool   `mapstructure:"insecure"`
	CACert       string `mapstructure:"cacert"`
	BindDN       string `mapstructure:"bind_username"`
