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'.
Keep the immediate direct deps at the library that depends on them,
declare deps as PUBLIC so that targets that link against that library
get the library's deps as transitive deps.
Break dep cycle between blockchain_db <-> crytonote_core.
No code refactoring, just hide cycle from cmake so that
it doesn't complain (cycles are allowed only between
static libs, not shared libs).
This is in preparation for supproting BUILD_SHARED_LIBS cmake
built-in option for building internal libs as shared.
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.
This adds [snap](https://snapcraft.io) packaging to the project. See the
link for more information on snaps. Snap packages install on all Linux
distributions. On Ubuntu, snap confinement with apparmor and seccomp
provide an additional layer of security.
This snap sets up monerod as a systemd service, which should start
immediately on install. To access the wallet CLI, simply run `monero`
(/snap/bin/monero). I think it's a really quick & easy way to get
started with monero.
I've made some opinionated decisions in the packaging just to kick this
off, but I'm happy to iterate on this stuff.
This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.
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.
This plugs a privacy leak from the wallet to the daemon,
as the daemon could previously see what input is included
as a transaction input, which the daemon hadn't previously
supplied. Now, the wallet requests a particular set of
outputs, including the real one.
This can result in transactions that can't be accepted if
the wallet happens to select too many outputs with non standard
unlock times. The daemon could know this and select another
output, but the wallet is blind to it. It's currently very
unlikely since I don't think anything uses non default
unlock times. The wallet requests more outputs than necessary
so it can use spares if any of the returns outputs are still
locked. If there are not enough spares to reach the desired
mixin, the transaction will fail.
Simplewallet improperly skipped the restore from height code if
restoring a deterministic wallet AND not specifying a wallet file in the
command line. The other generate options require a wallet file as an
argument, which prevents "ask_wallet_create_if_needed()" from being
called, which in turn causes "m_generate_new" to remain unset.
Specifying a wallet file at launch with --restore-deterministic emulated
this behavior.

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".
It sets the max number of threads to use for a parallel job.
This is different that the number of total threads, since monero
binaries typically start a lot of them.
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.

modified: src/wallet/wallet2.h
Update to fix unconfirmed balance and give a slightly more verbose and informative confirmation message for transfers
^C when in RPC mode would not save the wallet while it was still
refreshing after starting up.
Also, save the wallet out of the signal handler. We don't want
to call complex stuff in a signal handler.
b4eada9 wallet: make load_keys check types when loading JSON (moneromooo-monero)
3e55725 wallet: make the JSON reading type safe (moneromooo-monero)
f8d05f3 common: new json_util.h (moneromooo-monero)
This allows appropriate action to be taken, like displaying
the reason to the user.
Do just that in simplewallet, which should help a lot in
determining why users fail to send.
Also make it so a tx which is accepted but not relayed is
seen as a success rather than a failure.
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.
It would try to join the auto refresh thread, which would
only happen after it was done, which would take a long time
when doing so on a newly created wallet.

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.
There are various locale related bugs in various versions of boost,
where exceptions are thrown in boost::filesystem APIs when the
current locale is not to boost's liking. It's not clear what "not
to boost's liking" means in detail, though "en" and "en_US.UTF-8"
are not to its liking.
Fix it by running a test function that's known to throw in such
a case, and resetting LANG and LC_ALL to C if an exception is
thrown. In simplewallet, the locale is queried before that so the
correct translations will still be used.
Default to "simplewallet.log" in current directory when file path isn't
obtained from epee.
In this situation previously, it defaulted to the file name of ".log"
("" + ".log") in the current directory.
(Thanks to @sammy007 for reporting bug.)
An earlier version yet used "" + "/" + ".log" = "/.log", which resulted
in silently not logging in most cases, due to lack of permission.
Test:
PATH=$PATH:</path/to/simplewallet/folder> && simplewallet --wallet-file /dev/null
This results in epee not finding the executable's file path, so
simplewallet will now use a default log filename.
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.
Pros:
- smaller on the blockchain
- shorter integrated addresses
Cons:
- less sparseness
- less ability to embed actual information
The boolean argument to encrypt payment ids is now gone from the
RPC calls, since the decision is made based on the length of the
payment id passed.
A payment ID may be encrypted using the tx secret key and the
receiver's public view key. The receiver can decrypt it with
the tx public key and the receiver's secret view key.
Using integrated addresses now cause the payment IDs to be
encrypted. Payment IDs used manually are not encrypted by default,
but can be encrypted using the new 'encrypt_payment_id' field
in the transfer and transfer_split RPC calls. It is not possible
to use an encrypted payment ID by specifying a manual simplewallet
transfer/transfer_new command, though this is just a limitation
due to input parsing.
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.
boost doesn't support %zu for size_t, and the previous change
to %u could technically lose bits (though it would require splitting
a transfer into 4 billion transactions, which seems unlikely).
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".
Replace --set_log with --log-level for consistency.
Show default log level in usage.
Add --log-file for specifying log file path.
Document log file path.
Display log file path at startup.
As with display of seed, don't log view key and spend key.
Includes:
- display of viewkey at wallet creation
- "viewkey" command output
- "spendkey" command output
new update of the pr with network limits
more debug options:
discarding downloaded blocks all or after given height.
trying to trigger the locking errors.
debug levels polished/tuned to sane values.
debug/logging improved.
warning: this pr should be correct code, but it could make
an existing (in master version) locking error appear more often.
it's a race on the list (map) of peers, e.g. between closing/deleting
them versus working on them in net-limit sleep in sending chunk.
the bug is not in this code/this pr, but in the master version.
the locking problem of master will be fixed in other pr.
problem is ub, and in practice is seems to usually cause program abort
(tested on debian stable with updated gcc). see --help for option
to add sleep to trigger the error faster.
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)
simplewallet run without a wallet path argument should prompt again if
an invalid path was entered.
Validity here currently means the string isn't empty.
simple_wallet::seed()
- Check that wallet is deterministic.
simple_wallet::new_wallet()
- Prompt for seed language only if it's a non-deterministic wallet,
along with previous conditions.
simple_wallet::open_wallet()
- Fixed check for deterministic wallet (flag based on command line
non-deterministic argument was used before, but it's inapplicable to
opening an existing wallet).
- As with deterministic wallet, non-deterministic also included to be
rewritten to new JSON format file. That's what's done for newly
generated non-deterministic wallets, so old versions should be
updated to same format.

Simplewallet should now do a DNS query on an address if it fails to
convert the given string to a binary representation of an address
(base58->binary). It will prompt the user, telling of what the "url"
passed was, what monero address it translated to, and whether or not
DNSSEC validation was a success, and ask for a confirmation that these
are all acceptable.
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.
