This PR moves any address notifications outside of the
db transaction that creates them. This is known to have
resulted in deadlocks, since chainClient.NotifyReceived
could block the db transaction from committing.
Doing so also prevents the situation where we send
notifications about the new addresses, but the db txn
fails to commit and the addresses are in fact never
created.
In this commit, ensure that upon restart, if any of the full-node based
backends we support reject the transaction, then we'll properly remove
the now invalid transaction from the tx store. Before this commit, we
could miss a few errors from bitcoind. To remedy this, we explicitly
catch those errors, but then also attempt to precisely catch the set of
generic json RPC errors that can be returned.
In this commit, we fix a bug introduced in an earlier commit. Before
this commit, we would *always* remove an unmined transaction if it
failed to be accepted by the network upon restart. Instead, we should
only remove transaction that are actually due to us trying to spend an
output that’s already spent, or an orphan transaction.
In this commit, we extend the PublishTransction method to be a more
general semi reliable transaction broadcast mechanism. We do this by
removing the special casing for neutrino. With this change, we’ll
_always_ write any transactions to be broadcast to disk. A side effect
of this, is that if the transaction doesn’t *directly* involve any
outputs we control, then it’ll linger around until a restart, when we
try to rebroadcast, and observe that it has bene rejected.
In this commit, we do away with the internal relayFee all together.
Instead, we’ll pass in the fee rate when we’re crafting any
transactions. This allows the caller to manually dictate their desired
fee rate.
During the time of initial block hash catch-up, it is possible to
request an address be generated. This commit updates the active
addresses by calling `w.activeData` after the catch-up is complete.
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.
Previously, this would not increment the spendable balance for matured
coinbase outputs and would only increment the immature balance if the
output was still immature.
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.
This changes the wallet.Open function signature to remove the database
namespace parameters. This is done so that the wallet package itself
is responsible for the location and opening of these namespaces from
the database, rather than requiring the caller to open these ahead of
time.
A new wallet.Create function has also been added. This function
initializes a new wallet in an empty database, using the same
namespaces as wallet.Open will eventually use. This relieves the
caller from needing to manage wallet database namespaces explicitly.
Fixes#397.
