| * Remove blocks_per_sync limitsHoward Chu2016-08-311-1/+1
| | | | | | | | | | | | The code used to cap at 5000 blocks per sync. It also treated 0 as 1. Remove these checks; if specified as 0 do no periodic syncs at all. Then the user is responsible for syncing in some external process.
* | core: faster find_blockchain_supplementmoneromooo-monero2016-08-311-6/+2
|/ | | | | | | | | | | | | Since this queries block heights for blocks that may or may not exist, queries for non existing blocks would throw an exception, and that would slow down the loop a lot. 7 seconds to go through a 30 hash list. Fix this by adding an optional return block height to block_exists and using this instead. Actual errors will still throw an exception. This also cuts down on log exception spam.

* New "Halfway RingCT" outputs for coinbase transactionsmoneromooo-monero2016-08-281-14/+10
| | | | | | | | | | | | | | | When RingCT is enabled, outputs from coinbase transactions are created as a single output, and stored as RingCT output, with a fake mask. Their amount is not hidden on the blockchain itself, but they are then able to be used as fake inputs in a RingCT ring. Since the output amounts are hidden, their "dustiness" is not an obstacle anymore to mixing, and this makes the coinbase transactions a lot smaller, as well as helping the TXO set to grow more slowly. Also add a new "Null" type of rct signature, which decreases the size required when no signatures are to be stored, as in a coinbase tx.
* rct: rework v2 txes into prunable and non prunable datamoneromooo-monero2016-08-281-9/+15
| | | | Nothing is pruned, but this allows easier changes later.
* rct: rework the verification preparation processmoneromooo-monero2016-08-281-126/+96
| | | | | | | | | | The whole rct data apart from the MLSAGs is now included in the signed message, to avoid malleability issues. Instead of passing the data that's not serialized as extra parameters to the verification API, the transaction is modified to fill all that information. This means the transaction can not be const anymore, but it cleaner in other ways.

* rct: avoid the need for the last II elementShen Noether2016-08-281-8/+6
| | | | | | This element is used in the generation of the MLSAG, but isn't needed in verification. Also misc changes in the cryptonote code to match, by mooo.

|
* move the rct commitments to the output_amounts databasemoneromooo-monero2016-08-281-23/+2
| | | | | | | | | | | | | | | | | | | Since these are needed at the same time as the output pubkeys, this is a whole lot faster, and takes less space. Only outputs of 0 amount store the commitment. When reading other outputs, a fake commitment is regenerated on the fly. This avoids having to rewrite the database to add space for fake commitments for existing outputs. This code relies on two things: - LMDB must support fixed size records per key, rather than per database (ie, all records on key 0 are the same size, all records for non 0 keys are same size, but records from key 0 and non 0 keys do have different sizes). - the commitment must be directly after the rest of the data in outkey and output_data_t.
* ringct: do not serialize what can be reconstructedmoneromooo-monero2016-08-281-20/+67
| | | | | | The mixRing (output keys and commitments) and II fields (key images) can be reconstructed from vin data. This saves some modest amount of space in the tx.
* Use the supplied hard fork version in validate_miner_transactionmoneromooo-monero2016-08-281-1/+1

* Fake outs set is now decided by the walletmoneromooo-monero2016-08-111-0/+19
| | | | | | | | | | | | | | | | | | 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.
* new unlocked parameter to output_histogrammoneromooo-monero2016-08-011-2/+2
| | | | | | | | This constrains the number of instances of any amount to the unlocked ones (as defined by the default unlock time setting: outputs with non default unlock time are not considered, so may be counted as unlocked even if they are not actually unlocked).

| | | | | | | | | | | | | | | | | | | | | | | | | | | When reaching the tail emission phase, the amount of coins will eventually go over MONEY_SUPPLY, overflowing 64 bits. There was a check added to blockchain_storage, but this was not ported to the blockchain DB version. Reported by smooth.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a list of existing output amounts along with the number of outputs of that amount in the blockchain. The daemon command takes: - no parameters: all outputs with at least 3 instances - one parameter: all outputs with at least that many instances - two parameters: all outputs within that many instances The default starts at 3 to avoid massive spamming of all dust outputs in the blockchain, and is the current minimum mixin requirement. An optional vector of amounts may be passed, to request histogram only for those outputs.

Many areas for improvement in clarity and design have been noted, as well as cruft to be removed.
