9b8a062 Make a small test change (Oyvind Kvanes)
This change adds the ability to create a new unsigned transaction
from a watch only wallet, and save it to a file. This file can
then be moved to another computer/VM where a cold wallet may load
it, sign it, and save it. That cold wallet does not need to have
a blockchain nor daemon. The signed transaction file can then be
moved back to the watch only wallet, which can load it and send
it to the daemon.
Two new simplewallet commands to use it:
sign_transfer (on the cold wallet)
submit_transfer (on the watch only wallet)
The transfer command used on a watch only wallet now writes an
unsigned transaction set in a file called 'unsigned_monero_tx'
instead of submitting the tx to the daemon as a normal wallet does.
The signed tx file is called 'signed_monero_tx'.
We keep 1, 2, 3 multipliers till the fee decrase from 0.01/kB
to 0.002/kB, where we start using 1, 20, 166 multipliers.
This ensures the higher multiplier will compensate for the
block reward penalty when pushing past 100% of the past median.
The fee-multiplier wallet setting is now rename to priority,
since it keeps its [0..3] range, but maps to different multiplier
values.
The "transfer" simplewallet command is renamed to "transfer_original".
"transfer_new" is renamed "transfer", "transfer_rct" is removed,
and the new "transfer" now selects rct or non rct transactions
based on the current block height.

They are used to export a signed set of key images from a wallet
with a private spend key, so an auditor with the matching view key
may see which of those are spent, and which are not.
Signing is done using the spend key, since the view key may
be shared. This could be extended later, to let the user choose
which key (even a per tx key).
simplewallet's sign/verify API uses a file. The RPC uses a
string (simplewallet can't easily do strings since commands
receive a tokenized set of arguments).
Fee can now be multiplied by 2 or 3, if users want to give
priority to their transactions. There are only three levels
to avoid too much fingerprinting. Default is 1 (minimum fee).
The default multiplier can be set by "set fee-multiplier X".
We want to lock operations which access the blockchain in
wallet2. We also want the background refresh to happen again
when we cancel a foreground refresh. Wrap the locking setup
in a macro so it doesn't get copy/pasted/mangled, and use
a scope exit trick to ensure it's always properly restored.
This sends all outputs in a wallet to a given address, alleviating
the difficulty people have had trying to send all monero but
being left with some small amount left.
With the change in mixin rules for v2, the "annoying" outputs are
slightly changed. There is high correlation between dust and
unmixable, but no equivalence.
It takes a filename containing JSON data to generate a wallet.
The following fields are valid:
version: integer, should be 1
filename: string, path/filename for the newly created wallet
scan_from_height: 64 bit unsigned integer, optional
password: string, optional
viewkey: string, hex representation
spendkey: string, hex representation
seed: string, optional, list of words separated by spaces
Either seed or private keys should be given. If using private
keys, the spend key may be omitted (the wallet will not be
able to spend, but will see incoming transactions).
If scan_from_height is given, blocks below this height will not
be checked for transactions as an optimization.
Blockchain hashes and key images are flushed, and blocks are
pulled anew from the daemon.
The console command is shortened to match bc_height.
This should make it a lot easier on users who are currently
told to remove this particular cache file but keep the keys
one, etc, etc.
^C while in manual refresh will cancel the refresh, since that's
often an annoying thing to have to wait for. Also, a manual refresh
command will interrupt any running background refresh and take
over, rather than wait for the background refresh to be done, and
look to be hanging.
The daemon will be polled every 90 seconds for new blocks.
It is enabled by default, and can be turned on/off with
set auto-refresh 1 and set auto-refresh 0 in the wallet.
Height seemed to be flying all over the place on a rescan here.
Logging to a file shows the heights are actually correct, and
this is some kind of screen refresh artifact. Flush after \r
and update less often to reduce this effect a lot.
This obsoletes the need for a lengthy blockchain rescan when
a transaction doesn't end up in the chain after being accepted
by the daemon, or any other reason why the wallet's idea of
spent and unspent outputs gets out of sync from the blockchain's.
It should avoid a lot of the issues sending more than half the
wallet's contents due to change.
Actual output selection is still random. Changing this would
improve the matching of transaction amounts to output sizes,
but may have non obvious effects on blockchain analysis.
Mapped to the new transfer_new command in simplewallet, and
transfer uses the existing algorithm.
To use in RPC, add "new_algorithm: true" in the transfer_split
JSON command. It is not used in the transfer command.
The new save_watch_only saves a copy of the keys file without the
spend key. It can then be given away to be used as a normal keys
file, but with no spend ability.
Sends all the dust to your own wallet. May fail (if the fee required
is more than the dust total). May end up paying most of the dust in fees.
Unlocked dust total is now also displayed in "balance".
wallet RPC now uses wallet2::create_transactions and wallet2::commit_tx instead
of wallet2::transfer. This made it possible to add the RPC call /transfer_split, which
will split transactions automatically if they are too large. The old call to
/transfer will return an error stating to use /transfer_split if multiple
transactions are needed to fulfill the request.
