This change saves (at most) the last 20 block hashes to disk. Upon
btcd connect, in the handshake, btcwallet checks whether btcd's best
chain still contains these blocks, starting from the most recently
added block and continuing until the earliest saved. If any blocks
are missing, Tx history and UTXOs from any blocks no longer in the
chain are removed, and a rescan is started from after the best block
still in the main chain.
If all previous block hashes are exhausted (either due to a large
reorg, or because not enough blocks have been seen), a full rescan is
triggered (full meaning from the earliest block that matters to this
wallet) since the last synced up to point is no longer available.
The previous 20 seen block hashes are saved to the wallet file, which
required bumping the file version. Older wallets written with lesser
versions will use the previous reading function, making this change
backwards compatible.
This change copies the listening behavior of btcd by replacing the
--serverport option with --listen. By default, btcwallet will only
listen for localhost connections, but with this change it will be
possible to add listeners for remote connections.
This was added due to finding a bug with updateConfigWithActiveParams.
After consulting the btcd source code, the bug was fixed by replacing
the function (as it was no longer needed) when the new listening code
was introduced.

This changes the locations that account files (wallet.bin, utxo.bin,
and tx.bin) are searched for when opening or disk syncing accounts.
Previously, files were saved in the following layout:
~/.btcwallet/
- btcwallet/
- wallet.bin
- tx.bin
- utxo.bin
- btcwallet-AccountA/
- wallet.bin
- tx.bin
- utxo.bin
This format had two issues. First, each account would require its own
directory, causing a scalability issue on unix (and perhaps other)
platforms. Second, there was no distinction between testnet and
mainnet wallets, and if mainnet support was enabled, btcwallet would
attempt to open accounts with testnet wallets.
Instead, the following file structure is now used:
~/.btcwallet/
- testnet/
- wallet.bin
- tx.bin
- utxo.bin
- AccountA-wallet.bin
- AccountA-tx.bin
- AccountA-utxo.bin
This solves both of the previously-mentioned issues by requiring only
two subdirectories (one each for the testnet and mainnet bitcoin
networks), and by separating the locations to open and save testnet
and mainnet account files.
At startup, a check for the old account file structure is performed.
If found, files are moved to the new locations, and the old account
directories are removed. Account files are moved to the testnet
directory, as only testnet support is currently enabled.
The version has been bumped to 0.1.1 to reflect this change.
Fixes#16.
This change adds a new websocket extension command,
listalltransaction, which works just like listtransactions except it
does not take the count or from optional args, and will return an
array of all transaction details. Notifications for newly-added
transactions are now sent to frontends as well, using the newtx
notification.
No support for updating tx details or removing failed txs is
implemented yet, and will be when cleanly failing a tx send is
implemented later.
This change better organizes account handling by creating a new
AccountStore type and accountstore global variable, with receiver
funcs for all operations that require all accounts. More Account
funcs are also added to clean up account handling in the RPC code.
Intial work on this done by dhill.
