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.
This commit also allows bitcoind back-end to return block timestamp
in `BlockStamp()` and prevents logging and notification of events
until after the client wallet requests notifications.
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.
This commit resolves a deadlock observed when attempting
to generate addresses. There were a few cases, particularly
in chainAddressRowToManaged and loadAccountInfo, which accessed
the public IsLocked() method of the Manager, even though the
shared mutex had already been acquired.
The solution is to create an internal isLocked() method, which
can be safely called assuming the manager's mutex has already been
acquired. As the comments above both of the methods in question
specify, we can assume the Manager's mutex *is* already acquired.
This commit also reduces some unnecessary code duplication, since
the recent changes left both a Locked() and IsLocked() method that
perform the same functionality. IsLocked() was favored as it more
clearly indicates that the returned value is a boolean.
In this commit, we fix a deadlock bug that was introduced recently.
This can happen when ForEachActiveAccountAddress or
ForEachActiveAddress is called, as these internally need to grab the
mutex of the manager (within the scoped manager) in order to check if
the manager is locked or not.
In this commit, we add a database migration from version 4 to version 5.
We also take this opportunity to clean up the old migration code. This
is no longer needed as wallets very old can simply go back in the prior
git history to migrate to version 4, then go from there to version 5.
In this commit, we remove many of the methods in the Manager struct as
they’ve now be been replicated within a scoped format for each of the
ScopedKeyManagers.
A major change is that we’ll now actually store the master HD private
and public keys. This required as in order to create new scopes, we
need access to the master HD private key as hardened derivation is
required in accordance with BIP43.
The initial creation of the manager namespaces has also been extended
to create the namespaces and keys for the set of default key scopes.
Finally, a series of utility method has been added to allow callers to
create ScopedKeyManagers for arbitrary sets of scopes.
