In this commit, we add a new test case to the wtxmgr store to ensure
that duplicate outputs don't exists within the store. It's possible for
this to happen if an output is marked as unconfirmed credit, then marked
as confirmed once it confirms, and once again marked as unconfirmed. It
can be marked as unconfirmed again due to the backend notifying the
client about this transaction. Ideally this should not happen, but the
root cause is much more involved. As a stop gap, we'll ensure that
outputs can be marked as unconfirmed credits more than once whatsoever.
As is, the test case fails, which proves that this is an issue. A later
commit will resolve this and the test case should pass.
In this commit, we add a set of double spend tests to ensure that we can
properly detect and handle them. At this point, we do not do this, but a
follow up commit will address this.
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.
While making these tests compile and pass, we ended up tripping on the
broken bolt cursor usage painfully discovered in dcrwallet, so i've
ported that fix over as well. Would have learned about that a whole
lot sooner if those tests were never disabled..
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 commit corrects various things found by the static checkers
(comments, unkeyed fields, return after some if/else).
Add generated files and legacy files to the whitelist to be ignored.
Catch .travis.yml up with btcd so goclean can be run.
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.
