Overview

Example (OrderCacheItems) 
items := map[string]fileCacheItem{
	"one": {
		localPath:        "path/one.bin",
		fileSize:         10 * 1024 * 1024,
		timestampUnixSec: 1234567891,
	},
	"three": {
		localPath:        "path/three.bin",
		fileSize:         30 * 1024 * 1024,
		timestampUnixSec: 1234567893,
	},
	"two": {
		localPath:        "path/two.bin",
		fileSize:         20 * 1024 * 1024,
		timestampUnixSec: 1234567892,
	},
	"four": {
		localPath:        "path/four.bin",
		fileSize:         40 * 1024 * 1024,
		timestampUnixSec: 1234567894,
	},
}

byAge, totalSize := orderCacheItems(items)
fmt.Printf("Total size: %v\n", totalSize)

for _, i := range byAge {
	fmt.Printf("path: %v, ts: %v, size: %v\n", i.localPath, i.timestampUnixSec, i.fileSize)
}

Output:

Total size: 104857600
path: path/four.bin, ts: 1234567894, size: 41943040

Types

type ConnectToken added in v4.32.3 

type ConnectToken struct {
	Id            string `bson:"_id"`
	ExpiryUnixSec int64
	User          jwtparser.JWTUserInfo
	Permissions   []string
}

type HandlerContext 

type HandlerContext struct {
	Session  *melody.Session
	SessUser SessionUser
	Melody   *melody.Melody
	Svcs     *services.APIServices
}

type LogWriter added in v4.33.5 

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

func (LogWriter) Write added in v4.33.5 

func (w LogWriter) Write(p []byte) (n int, err error)

type SessionUser 

type SessionUser struct {
	SessionId              string
	User                   *protos.UserInfo
	Permissions            map[string]bool
	MemberOfGroupIds       []string
	ViewerOfGroupIds       []string
	NotificationSubscribed bool
}

func CreateDBUser 

func CreateDBUser(sessionId string, jwtUser jwtparser.JWTUserInfo, db *mongo.Database, defaultGroupIdToJoin string, log logger.ILogger) (*SessionUser, error)

If we have a successful login and the user is not in our DB, we write a default record for them, so if they change their details we have a spot to save it already NOTE: This is (at time of writing) the only way to add a user to the DB

func GetSessionUser 

func GetSessionUser(s *melody.Session) (SessionUser, error)

func MakeSessionUser 

func MakeSessionUser(sessionId string, userId string, permissions map[string]bool, db *mongo.Database) (*SessionUser, error)

JWT user has the user ID and permissions that we get from Auth0. The rest is handled within PIXLISE, so lets read our DB to see if this user exists and get their user name, email, icon, etc

type UserImpersonationItem added in v4.32.1 

type UserImpersonationItem struct {
	// The user id who is doing the impersonating
	Id string `bson:"_id"`

	// The id of the user we're pretending to be
	ImpersonatedId string

	// For ease of debugging, we don't "time it out" right now or anything...
	TimeStampUnixSec uint32
}
