Fetch unspent info from one of multiple source source options + fallback #25

Closed patricklodder closed 10 years ago

patricklodder commented 10 years ago

The following 3 commits implement sweep source changes, each commit delivers a working client.

e8f6157 (prep & cleanup) implements:

Extracted private functions for fetch, parse and balance calc
Put the dogechain.info unspent url in a static string
Removed leftover code that made fetch take at least 1500ms
Added state NOTHING_TO_DO to diff between errors and 0 vouts
only process vouts if fetch/parse was successful
some minor syntactical improvements

e3a849e (multi source) implements:

SoChain (https://chain.so) as a fallback source, in case dogechain.info is unreachable.
Removed reference to dogechain.info from the getbalance popup.

f245c0a (random source) implements:

Randomly select which provider to choose first. This spreads the load.

Edited the source order randomizer in f245c0a to be performed on the private member rather than cloning the static final at every sweep. Cleaner implementation.
