* db_lmdb: add info in an error message when we can't get an outputmoneromooo-monero2016-12-011-1/+1
| | | | Will be useful to debug
* db_lmdb: guard against going out of sync on unexpected db resultsmoneromooo-monero2016-12-011-1/+1
| | | | | | | m_num_outputs keeps track of the number of outputs, which should be the same as the size of both the output_txs and output_amounts databases. If one goes out of sync, we need to throw to abort whatever it is we were doing.
* db_lmdb: minor pedantic tweaksmoneromooo-monero2016-12-011-8/+8
| | | | | | Add consts in a few places where it makes sense, avoid unnecessary memory reallocation where we know the full size needed at the outset, simplify and avoid memory copy.
* db_lmdb: set same packing format for output_data_t and pre_rct_output_data_tmoneromooo-monero2016-12-011-0/+3
| | | | | | For safety, though it seems to have been the case already. Also add a comment about the necessary layout identity.
* wallet: select part of the fake outs from recent outputsmoneromooo-monero2016-10-153-12/+30
| | | | | | | 25% of the outputs are selected from the last 5 days (if possible), in order to avoid the common case of sending recently received outputs again. 25% and 5 days are subject to review later, since it's just a wallet level change.

* cmake: transitive deps and remove deprecated LINK_*redfish2016-09-181-8/+2
| | | | | | | | | | | | | | 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.
* core: faster find_blockchain_supplementmoneromooo-monero2016-08-315-5/+16
| | | | | | | | | | | | | 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.
* db_lmdb: fix reorg with "halfway rct" coinbase outputsmoneromooo-monero2016-08-291-1/+3

* New "Halfway RingCT" outputs for coinbase transactionsmoneromooo-monero2016-08-281-2/+17
| | | | | | | | | | | | | | | 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.
* move the rct commitments to the output_amounts databasemoneromooo-monero2016-08-286-167/+60
| | | | | | | | | | | | | | | | | | | 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.
* add rct to the protocolmoneromooo-monero2016-08-282-0/+4
| | | | | It is not yet constrained to a fork, so don't use on the real network or you'll be orphaned or rejected.
* db_lmdb: update reset for recent db changesmoneromooo-monero2016-08-281-0/+10
| | | | | | | - we need to drop the new m_tx_indices database - we reset the version to current version This fixes the core tests failing to initialize.

| * new unlocked parameter to output_histogrammoneromooo-monero2016-08-013-9/+28
| | | | | | | | | | | | | | | | 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).

It removes the indirection and walking the amount output duplicate list for every amount in each requested tx. "tx_outputs" is used by: Amount output indices are needed for wallet refresh. Global output indices are needed for removing a tx. Both amount output indices and global output indices are now stored in an array of 64-bit unsigned ints: tx_outputs[<tx_hash>] -> [ <a1_oi, a1_gi, a2_oi, a2_gi, ...> ] Previously it was: tx_outputs[<tx_hash>] -> duplicate list of <a1_gi, a2_gi, a3_gi, ...> The amount output list had to be walked for every amount in order to find each amount's output index, by comparing the amount's global output index with each one in the duplicate list until a match was found.

* | New RPC and daemon command to get output histogrammoneromooo-monero2016-03-265-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
