This change adds support for the listtransactions RPC command. To
properly reply to this command, additonal information about received
transactions was added, and is now saved in an account's tx.bin file.
Additionally, when sending a transaction, a *tx.SendTx is now saved to
the Tx store, and is included in listtransactions replies under the
"send" category.
WARNING: All account's tx.bin and utxo.bin files should be removed
before running with this change, or else the files may not be read
correctly. Removing tx.bin is not an issue as it was not being used
before, and was being saved with incorrect data. Removing utxo.bin is
not an issue as it will just trigger a rescan on next start. File
format versions are now included in both files, so automatic updates
from previous file formats will be possible with future changes.
Fixes#12.
When a wallet is opened, a rescan request will be sent to btcd with
all active addresses from the wallet, to rescan from the last synced
block (now saved to the wallet file) and the current best block.
As multi-account support is further explored, rescan requests should
be batched together to send a single request for all addresses from
all wallets.
This change introduces several changes to the wallet, tx, and utxo
files. Wallet files are still compatible, however, a rescan will try
to start at the genesis block since no correct "last synced to" or
"created at block X" was saved. The tx and utxo files, however, are
not compatible and should be deleted (or an error will occur on read).
If any errors occur opening the utxo file, a rescan will start
beginning at the creation block saved in the wallet.
This is a big change that also many general fixes to problems found
when creating transactions. In particular the Utxo and Tx formats and
serialization functions were updated with additional information that
would be necessary for rolling back old utxo and tx data data after
btcd chain switches. This change also implements the json methods
'sendfrom' and 'sendmany' to create a new transaction based on a
frontend request.
Transactions are currently not sent to btcd since the tx relay code is
not finished yet, so a temporary error is returned back to frontends
who try to send new transactions.
