Overview

Package dbmirror is a package to create a database which is almost exactly the same as osu!'s beatmap database.

Functions

func Discover

func Discover(c *osuapi.Client, db *sql.DB) error

Discover discovers new beatmaps in the osu! database and adds them.

func DiscoverEvery

func DiscoverEvery(c *osuapi.Client, db *sql.DB, successWait, errorWait time.Duration)

DiscoverEvery runs Discover and waits for it to finish. If Discover returns an error, then it will wait errorWait before running Discover again. If Discover doesn't return any error, then it will wait successWait before running Discover again.

func SetHasVideo

func SetHasVideo(f func(int) (bool, error))

SetHasVideo sets the hasVideo function to the one passed.

func StartSetUpdater

func StartSetUpdater(c *osuapi.Client, db *sql.DB)

StartSetUpdater does batch updates for the beatmaps in the database, employing goroutines to fetch the data from the osu! API and then write it to the database.
