Rather than the main package being responsible for opening the address
and transaction managers, the namespaces of these components are
passed as parameters to the wallet.Open function.
Additionally, the address manager Options struct has been split into
two: ScryptOptions which holds the scrypt parameters needed during
passphrase key derivation, and OpenCallbacks which is only passed to
the Open function to allow the caller to provide additional details
during upgrades.
These changes are being done in preparation for a notification server
in the wallet package, with callbacks passed to the Open and Create
functions in waddrmgr and wtxmgr. Before this could happen, the
wallet package had to be responsible for actually opening the managers
from their namespaces.
If a long reorganize occurs farther back than the last saved recent
block hash (currently max 20 are saved) a full rescan is triggered
since there is no guarantee the previous blocks weren't also removed
in the reorg. In this case, the address manager was set unsynced, but
transaction history was not rolled back as well. This commit corrects
this by unconfirming all transactions but those in the genesis block.
StartWithdrawal now persists the WithdrawalStatus before returning, and also
returns a previously saved one in subsequent calls with the same parameters.
All transactions since the specified block (or the genesis block if
left unspecified) should be included in the result array
Along with this fix, update the help descriptions to mention that the
target confirmations parameter is not considered when including
transactions in the result object. That is, transactions with a
height greater than the height of the lastblock in the result object
are still included.
Fixes#263.
To increase compatibility with Bitcoin Core Wallet, additional fields
were added to and other fields made optional for the listtransactions
and gettransaction results structs. For both, fee was changed to be
optional (including the zero value is allowed).
If the account number to name index mapped the default account name to
an alias, the upgrade would not succeed and the upgrade would be
aborted (and rolled back).
This became a problem for upgrading old (pre-v3) wallets since the v3
upgrade did not rename the previous "" account to "default", but
instead just created an alias.
Fix tested by @dajohi, who ran into this issue with a wallet upgrade
from an older keystore version.
Rather than disallowing the default account to be renamed as was
proposed in #245 (and implemented in #246), the default account name
is no longer considered a reserved name by the address manager.
Instead, it is simply the initial name used for the first initial
account.
A database upgrade removes any additional aliases for the default
account in the database. This prevents a lookup for some name which
is not an account name from mapping to the default account
unexpectedly (potentially preventing incorrect account usage from the
RPC server due to bad iteraction with default parameters).
All unset account names in a JSON-RPC request are expected to be set
nil by btcjson. This behavior depends on btcsuite/btcd#399.
Additionally, the manager no longer considers the wildcard * to be a
reserved account name. Due to poor API decisions, the RPC server
overloads the meaning of account fields to optionally allow referring
to all accounts at a time, or a single account. This is not a address
manager responsibility, though, as a future cleaner API should not use
multiple differet meanings for the same field across multiple
requests. Therefore, don't burden down future APIs with this quirk
and prevent incorrect wildcard usage from the RPC server.
Closes#245.
btcrpcclient commit 9ca93b30ad11ec34348d2d788c58019571bf9524 switched
the client to btcjson v2 and broke the wallet build. This change is
the minimum amount of work to make wallet work again.
The rpc server still uses btcjson v1, so there will be 2 versions of
btcjson linked in the resulting binary. This is not optimal but not
compiling is worse.
This a refactor of the btcwallet main package to create a new wallet
package.
The main feature of this package is the integration of all the other
wallet components (waddrmgr, txstore, and chain) and the Wallet type is
'runnable', so it will be continuously updating itself against changes
notified by the remote btcd instance.
It also includes several methods which provide access to information
necessary to run a wallet RPC server.
The createtemp flag is used to create a temporary simnet wallet for
use with btcsim or other testing suites.
The flag only works if the datadir and network to use it on (simnet)
are specified.
After starting btcwallet with the flag, the wallet immediately opens
and is functional.
This introduce a new internal package to deal with the explicit
clearing of data (such as private keys) in byte slices, byte arrays
(32 and 64-bytes long), and multi-precision "big" integers.

Removes an XXX from the votingpool package.
This commit makes the creation and updating of the address manager more
explicit so it's easier to upgrade in the future.
In particular, rather than treating the initial creation as an upgrade by
relying on creating the initial buckets on the fly on each load, the code
now explicitly provides distinct create and upgrade paths that are invoked
from the Create and Open functions, respectively.
It also adds some commented out sample code to illustrate how upgrades
should be done and a check to ensure bumping the version number without
writing upgrade code results in a new error, ErrUpgrade, being returned.
Finally, a test has been added for the new functionality.
Otherwise, if the websocket connection to btcd is lost and
reestablished, there is no sync to the current best block, and btcd
will not notify wallet of new relevant transactions.
