var (
	// ErrUserNotFound indicates that a user name was not found in the
	// database.
	ErrUserNotFound = errors.New("user not found")

	// ErrUserExists indicates that a user already exists in the database.
	ErrUserExists = errors.New("user already exists")

	// ErrShutdown is emitted when the database is shutting down.
	ErrShutdown = errors.New("database is shutting down")
)

Functions

func EncodeUser

func EncodeUser(u User) ([]byte, error)

EncodeUser encodes User into a JSON byte slice.

Types

type Database

type Database interface {
	// User functions
	UserGetByUsername(string) (*User, error) // Return user record given the username
	UserGetById(uuid.UUID) (*User, error)    // Return user record given its id
	UserNew(User) error                      // Add new user
	UserUpdate(User) error                   // Update existing user
	AllUsers(callbackFn func(u *User)) error // Iterate all users

	// Close performs cleanup of the backend.
	Close() error
}

Database interface that is required by the web server.

type Identity

type Identity struct {
	Key         [identity.PublicKeySize]byte // ed25519 public key
	Activated   int64                        // Time key as activated for use
	Deactivated int64                        // Time key was deactivated
}

Identity wraps an ed25519 public key and timestamps to indicate if it is active. If deactivated != 0 then the key is no longer valid.

func (*Identity) IsActive

func (i *Identity) IsActive() bool

IsActive returns whether the identity is active.

func (*Identity) String

func (i *Identity) String() string

String returns a hex encoded string of the identity key.

type ProposalCredit

type ProposalCredit struct {
	PaywallID       uint64 // ID of the proposal paywall that created this credit
	Price           uint64 // Price this credit was purchased at in atoms
	DatePurchased   int64  // Unix timestamp of when the credit was purchased
	TxID            string // Payment transaction ID
	CensorshipToken string // Censorship token of proposal that used this credit
}

A proposal credit allows the user to submit a new proposal. Credits are created when a user sends a payment to a proposal paywall. A credit is automatically spent when a user submits a new proposal. When a credit is spent, it is updated with the proposal's censorship token and moved to the user's spent proposal credits list.

type ProposalPaywall

type ProposalPaywall struct {
	ID          uint64 // Paywall ID
	CreditPrice uint64 // Cost per proposal credit in atoms
	Address     string // Paywall address
	TxNotBefore int64  // Minimum timestamp for paywall tx
	PollExpiry  int64  // After this time, the paywall address will not be continuously polled
	TxID        string // Payment transaction ID
	TxAmount    uint64 // Amount sent to paywall address in atoms
	NumCredits  uint64 // Number of proposal credits created by payment tx
}

A proposal paywall allows the user to purchase proposal credits. Proposal paywalls are only valid for one tx. The number of proposal credits created is determined by dividing the tx amount by the credit price. Proposal paywalls expire after a set duration. politeiawww polls the paywall address for a payment tx until the paywall is either paid or it expires.

type User

type User struct {
	ID                              uuid.UUID // Unique user uuid
	Email                           string    // Email address + lookup key.
	Username                        string    // Unique username
	HashedPassword                  []byte    // Blowfish hash
	Admin                           bool      // Is user an admin
	PaywallAddressIndex             uint64    // Sequential id used to generate paywall address
	NewUserPaywallAddress           string    // Address the user needs to send to
	NewUserPaywallAmount            uint64    // Amount the user needs to send
	NewUserPaywallTx                string    // Paywall transaction id
	NewUserPaywallTxNotBefore       int64     // Transactions occurring before this time will not be valid.
	NewUserPaywallPollExpiry        int64     // After this time, the user's paywall address will not be continuously polled
	NewUserVerificationToken        []byte    // New user registration verification token
	NewUserVerificationExpiry       int64     // New user registration verification expiration
	ResendNewUserVerificationExpiry int64     // Resend request for new user registration verification expiration
	UpdateKeyVerificationToken      []byte    // Verification token for updating keypair
	UpdateKeyVerificationExpiry     int64     // Verification expiration
	ResetPasswordVerificationToken  []byte    // Reset password token
	ResetPasswordVerificationExpiry int64     // Reset password token expiration
	LastLoginTime                   int64     // Unix timestamp of when the user last logged in
	FailedLoginAttempts             uint64    // Number of failed login a user has made in a row
	Deactivated                     bool      // Whether the account is deactivated or not
	EmailNotifications              uint64    // Notify the user via emails

	// Access times for proposal comments that have been accessed by the user.
	// Each string represents a proposal token, and the int64 represents the
	// time that the proposal has been most recently accessed in the format of
	// a UNIX timestamp.
	ProposalCommentsAccessTimes map[string]int64

	// All identities the user has ever used.  User should only have one
	// active key at a time.  We allow multiples in order to deal with key
	// loss.
	Identities []Identity

	// All proposal paywalls that have been issued to the user in chronological
	// order.
	ProposalPaywalls []ProposalPaywall

	// All proposal credits that have been purchased by the user, but have not
	// yet been used to submit a proposal.  Once a credit is used to submit a
	// proposal, it is updated with the proposal's censorship token and moved to
	// the user's spent proposal credits list.  The price that the proposal
	// credit was purchased at is in atoms.
	UnspentProposalCredits []ProposalCredit

	// All credits that have been purchased by the user and have already been
	// used to submit proposals.  Spent credits have a proposal censorship token
	// associated with them to signify that they have been spent. The price that
	// the proposal credit was purchased at is in atoms.
	SpentProposalCredits []ProposalCredit
}

User is a politeiawww user.

func DecodeUser

func DecodeUser(payload []byte) (*User, error)

DecodeUser decodes a JSON byte slice into a User.

func (*User) ActiveIdentity

func (u *User) ActiveIdentity() *Identity

ActiveIdentity returns a user's active identity. A user will always have an active identity. This function panics if this assumption does not hold.

func (*User) PublicKey

func (u *User) PublicKey() string

PublicKey returns a hex encoded string of the user's active identity key.
