This is a hack fix to unblock lbrypool.net.
The paytxfee in lbcwallet is actually not being used anywhere, and is
hardcoded to DefaultRelayFee, which is 1000. Lbrycrd sets default to 0.
Also, since the paytxfee is not actually used/implemented, the
'settxfee' RPC is also
Now that we're able to fund transactions from multiple accounts within
different key scopes, we extend our transaction creation methods to
accept a key scope parameter as well, to determine the correct account
to select inputs from.
Previously, addresses that belong to a watch-only account would have a
derivation path using the internal account number used to identify
accounts within the databse, rather than the actual account number based
on the account's master public key child index. This wasn't an issue
before as only one account would exist within the wallet, the 0 account,
which is also the default. To ensure users of the DerivationPath struct
can arrive at addresses correctly, we introduce a new field
InternalAccount to denote the internal account number and repurpose the
existing Account field to its actual meaning.
This changes the database access APIs and each of the "manager"
packages (waddrmgr/wstakemgr) so that transactions are opened (only)
by the wallet package and the namespace buckets that each manager
expects to operate on are passed in as parameters.
This helps improve the atomicity situation as it means that many
calls to these APIs can be grouped together into a single
database transaction.
This change does not attempt to completely fix the "half-processed"
block problem. Mined transactions are still added to the wallet
database under their own database transaction as this is how they are
notified by the consensus JSON-RPC server (as loose transactions,
without the rest of the block that contains them). It will make
updating to a fixed notification model significantly easier, as the
same "manager" APIs can still be used, but grouped into a single
atomic transaction.
This updates both btcsuite and external dependencies to their latest
versions. In particular, gRPC was updated to version 1.0.3 and bolt
to 1.3.0.
The walletrpc package needed to be regenerated for the gRPC update.
While here, update the Travis-CI script so this can be tested there.
Since the coinbase maturity is now allowed to be defined per chain and
the old blockchain.CoinbaseMaturity constant has been removed, this
updates the code accordingly.
Also, update glide.lock to use the required version of btcd.
This updates all code to make use of the new chainhash package since the
old wire.ShaHash type and related functions have been removed in favor
of the abstracted package.
Also, while here, rename all variables that included sha in their name
to include hash instead.
Finally, update glide.lock to use the required version of btcd, btcutil,
and btcrpcclient.
