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.
In this commit, we create a new struct that houses the key derivation,
address management, and account management for a particular scope. A
scope consists of a (purpose, cointype) tuple. Additionally, each
ScopedKeyManager is able to generate internal/external addresses for a
specific *address type*. This make rescans easier as for each scope, we
know what type of output to look for within the chain.
The ScopedKeyManagers have two new primary methods that weren’t
previously present within the regular Manager:
* DeriveFromKeyPath
* NewRawAccount
These two methods allow callers a greater degree of control over the
way that accounted are created and addressed derived.
In this commit, we create new key spaces to allow users to store the
encrypted master priv/pub keys. This is required as in order to create
new scopes, we must do hardened derivation from the root key.
In this commit, we make a fundamental modification bucket structure
within the database. Most buckets are no under an additional layer of
nesting: the scope. The scope encapsulates which (purpose, coin type)
pair the address, accounts, and coin type keys belong to.
In this commit, we remove all direct references to BIP 44 as upcoming
changes will shift to a model that is no longer directly dependent on
BIP 44 in favor of restoring a layer of abstraction and allowing users
to manage multiple (purpose, coin type) scopes within the same
database.
In this commit, we introduce the concept of scopes for individual key
managers. Each scope will lock down a key manager to a particular
purpose and coin type within the BIP0043 hierarchy. Each scope will
also have a set address type schema. This schema will be consulted when
creating addresses for a particular scoped key manager.
Finally, we introduce 3 new default scopes:
* BIP 44
* BIP 84
* BIP 49++ (BIP49 but uses p2wkh for change addresses)
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 add a new method to the Store object that allows
callers to *manually* remove any conflicting transactions. At times,
it’s the case that while we were offline another transaction was
broadcast that double spends our own, or with the existence of RBF,
another replacement transaction was generated. In this case, when we
come back online, the tx will be rejected. Currently, we have no way of
removing such transaction sot avoid the retransmit-then-reject-dance.
This commit fixes that by adding RemoveUnminedTx.
This commit makes use of the recently added EstimateVirtualSize
method to estimated the size of a transaction when calculating
fees. This makes fee estimation more accurate when we are spending
segwit outputs, as before we wouldn't account for the witness
descount, resulting in overshooting fee estimates.
This commit adds a new method EstimateVirtualSize that calculates
the worst case estimate vsize for a transaction with a given set
of inputs and outputs. This method is aware of P2PKH, P2WPKH and
P2SH-P2WPKH inputs, and caulculates the transaction vsize with
the witness data included.
