This change moves the chain and network parameter definitions, along
with the default client and server ports, to a package for reuse by
other utilities (most notably, tools in the cmd dir). Along with it,
functions commonly used for config parsing and validation are moved to
an internal package since they will also be useful for distributed
tools.
18555 is the network port, and wallet cannot listen on this port.
Instead, follow the pattern laid out by mainnet, testnet3, and regtest
by listening on 18554 (one less than the network port).
This is an intial pass at converting the btcwallet and deps codebases
to pass a network by their parameters, rather than by a magic number
to identify the network. The parameters in params.go have been
updated to embed a *btcnet.Params, and all previous uses of cfg.Net()
have been replaced with activeNet.{Params,Net} (where activeNet is
the global var for the active network).
Although dependancy packages have not yet been updated from using
btcwire.BitcoinNet to btcnet.Params, the parameters are now accessible
at all callsites, and individual packages can be updated to use btcnet
without requiring updates in each external btc* package at once.
While here, the exported API for btcwallet internal library packages
(txstore and wallet) have been updated to pass full network parameters
rather than the btcwire definition of a network.
This adds an additional config option, -cafile, to specify the root
certificates checked when verifying a btcd TLC connection. btcd will
now automatically generate certs in
~/.btcd/data/{main,test}net/rpc.cert, and this file should be copied
to ~/.btcwallet/cert.pem.
The -btcdport option is also gone now, and replaced with -connect (or
-c), to specify both the hostname/ip and port of the server running
btcd.
This copies the functionality of btcd for choosing the ports for the
HTTP client (for btcd) and server (for frontends). On testnet, the
following ports are used as default:
- btcd: 18334
- frontends: 18332
When running with the (currently disabled) --mainnet flag, btcwallet
will choose the following ports by default:
- btcd: 8334
- frontends: 8332
Both ports can be overridden no matter the chosen network using the -b
and -p flags.
