Currently it is only possible to use `walletpassphrase` to unlock the
wallet when bitcoin is started in server mode.
Almost everything that manipulates the wallet in the RPC console
needs the wallet to be unlocked and is thus unusable without -server.
This is pretty unintuitive to me, and I'm sure it's even more confusing
to users.
Solve this with a very minimal change: by making the GUI start a
dummy RPC thread just to handle timeouts.
Split bitcoinrpc up into
- rpcserver: bitcoind RPC server
- rpcclient: bitcoin-cli RPC client
- rpcprotocol: shared common HTTP/JSON-RPC protocol code
One step towards making bitcoin-cli independent from the rest
of the code, and thus a smaller executable that doesn't have to
be linked against leveldb.
This commit only does code movement, there are no functional changes.
