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.
Remove the addresses field from TransactionDetails.Output. It is
assumed that the caller is able to deserialize the transaction and
encode the output scripts to addresses, so this is unnecessary server
overhead and conflicts with the current API philosophy of not
duplicating data already included in another field.
Since there is no additional data included for outputs not controlled
by the wallet, remove the `mine` specifier from the Output message and
replace it with an output index. Only include messages for controlled
outputs, rather than creating messages for both controlled and
uncontrolled outputs. Rename the repeated field from `outputs` to
`credits` to be consistent with the `debits` field.
Bump major API version as this is a breaking change.
Closes#408.
This commit enabled the wallet to properly spend nested and normal
p2wkh outputs under its control.
For regular p2wkh outputs, spending simply involves presenting the
original pub key, and signature as the witness data.
For nested p2wkh outputs, in addition to the above, the version zero
witness p2wkh witness program is placed in the sigScript in order to
allow clients who are aware of BIP 16 to validate the witness spend.
When spending a segwit output, the wallet also needs the input value of
the previous output script. Therefore when selecting outputs the input
value is now returned. Additionally when validating newly signed
outputs the input value as also passed into `txscript.Engine`
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.

Due to the way dust is calculated, if the transaction relay fee is
zero, then a zero output amount is not considered dust. As the
transaction authoring code used this dust check to determine whether a
change output can be included or not, it could create unnecessary
change outputs which return no value back to the wallet. Prevent this
by including an explicit check for zero values.
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.
These notifications were added to support real time updates for
btcgui. As the btcgui project is no longer being developed, there are
no more consumers of this API, and it makes sense to remove them given
their various issues (the largest being that notifiations are sent
unsubscribed to clients that may never be interrested in them).
A new notification server has already been added to the wallet package
to handle notifications in a RPC-server agnostic way. This server is
the means by which the wallet notifies changes for gRPC clients. If
per-client registered notifications are to be re-added for the
JSON-RPC server, they should be integrated with the new notification
server rather than using this legacy code.
This corrects and simplifies the shutdown logic for interrupts, the
walletrpc.WalletLoaderService/CloseWallet RPC, and the legacy stop RPC
by both stopping all wallet processes and closing the wallet database.
It appears that this behavior broke as part of the wallet package
refactor, causing occasional nil pointer panics and memory faults when
closing the wallet database with active transactions.
Fixes#282.
Fixes#283.
