Cache bucket map on client #16

Closed CurtTilmes closed 8 years ago

CurtTilmes commented 8 years ago

Have a config option to specify a bucket map cache file.

If the file doesn't exist on start up, ask for /bucket_map and cache it in that file.

If the client sees a redirect to a different server, invalidate and re-download it.

It very, very seldom changes at all, and even if it does, the redirect will make everything work anyway, but it will save a few queries to cache it. (The current Yars::Client doesn't rely on the redirects at all, it just downloads the bucket_map every single time -- That seems like overkill for something that might not change for years.)

I was just reviewing this, and there actually is a bucket map cache, but it isn't stored persistently, so there is one request for the bucket map per process.
