CheeseGull creates an unofficial "slave" database of the official osu! beatmap database, trying to keep every beatmap up to date as much as possible, as well as a cache middleman for osz files.
The main purpose for this is, as you can see from the owner of the repository, for running a sort of "beatmap mirror" for Ripple's osu! direct. We originally used an actual osu! beatmap mirror which had all of the beatmaps on osu! downloaded, but it ended up taking wayyyy too much space, and the cheapest server we could find that had at least 2 TB of HDD had an upload speed of 30mbit - as you can guess, this meant that for the Ripple users who didn't have a third world connection the download speed was pretty poor.
CheeseGull tries to hold a replica of the osu! database as updated as possible. Though of course, not having any way to see the latest updated beatmaps, or have a system for subscribing to updates to beatmap, or anything else which could help us identify what has been updated recently makes it very hard to do keep an updated copy at all times (Takeaway: the osu! API is completely shit). In order to do this, CheeseGull updates WIP, Pending or Qualified beatmaps when at least 30 minutes have passed since the time they were checked, whereas for all other beatmaps (including Graveyard, Ranked, Approved, etc) at least 4 days must have passed. This is not a problem for ranked/approved (it's highly unlikely for a ranked beatmap to ever change state, and Graveyard beatmaps are rarely resurrected, so there's that).
Beatmap downloads are also provided by going at
/d/<id>. In case the beatmap
is not stored in the local cache, the beatmap will be downloaded on-the-fly
(this assumes the machine's internet connection is fast enough to download a
beatmap before a HTTP timeout happens). In case the beatmap already is in the
cache, then well, as you can imagine, it is served straight from there. Oh, yes,
multiple people downloading a not cached beatmap at the same time is a case we
handle. Or should be able to handle, at least.
You can find binaries of the latest release here.
If you want to compile from source, if you have Go installed it should only be
go get github.com/osuripple/cheesegull away.
The only requirements at the moment are a MySQL server and an osu! account.

git checkout -b your-new-feature code . # make changes git add . git commit -m "Added thing" git push origin your-new-feature
Go to the GitHub website, and create a pull request.
If you want to test search using Sphinx, you will need to set it up. Here is the sphinx.conf used in production, you probably only need to change lines 23-35
(No, we're not using ElasticSearch. Search is meant to be fast and not take too much memory. Any Java solution can thus be tossed away since it does not suit these basic two requirements.)
