Overview

Package db provides a set type to track local/remote files with newness checks. We must do a certain amount of normalization in here. We will get fed paths with either native or wire-format separators and encodings depending on who calls us. We transform paths to wire-format (NFC and slashes) on the way to the database, and transform to native format (varying separator and encoding) on the way back out.

Functions

func DropDeltaIndexIDs added in v0.14.52 

func DropDeltaIndexIDs(db *Lowlevel)

DropDeltaIndexIDs removes all delta index IDs from the database. This will cause a full index transmission on the next connection.

func DropFolder 

func DropFolder(db *Lowlevel, folder string)

DropFolder clears out all information related to the given folder from the database.

func Need added in v1.10.0 

func Need(global FileVersion, haveLocal bool, localVersion protocol.Vector) bool

func UpdateSchema added in v0.14.52 

func UpdateSchema(db *Lowlevel) error

UpdateSchema updates a possibly outdated database to the current schema and also does repairs where necessary.

Types

type BlockFinder 

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

func NewBlockFinder 

func NewBlockFinder(db *Lowlevel) *BlockFinder

func (*BlockFinder) Iterate 

func (f *BlockFinder) Iterate(folders []string, hash []byte, iterFn func(string, string, int32) bool) bool

Iterate takes an iterator function which iterates over all matching blocks for the given hash. The iterator function has to return either true (if they are happy with the block) or false to continue iterating for whatever reason. The iterator finally returns the result, whether or not a satisfying block was eventually found.

func (*BlockFinder) String 

func (f *BlockFinder) String() string

type BlockList added in v1.4.0 

type BlockList struct {
	Blocks []protocol.BlockInfo `protobuf:"bytes,1,rep,name=blocks,proto3" json:"blocks" xml:"block"`
