10013e94 Protect node privacy by proper filtering in restricted-mode RPC answers (binaryFate)
2017-11-08Protect node privacy by proper filtering in restricted-mode RPC answersbinaryFate3-11/+42
This patch allows to filter out sensitive information for queries that rely on the pool state, when running in restricted mode. This filtering is only applied to data sent back to RPC queries. Results of inline commands typed locally in the daemon are not affected. In practice, when running with `--restricted-rpc`: * get_transaction_pool will list relayed transactions with the fields "last relayed time" and "received time" set to zero. * get_transaction_pool will not list transaction that have do_not_relay set to true, and will not list key images that are used only for such transactions * get_transaction_pool_hashes.bin will not list such transaction * get_transaction_pool_stats will not count such transactions in any of the aggregated values that are computed The implementation does not make filtering the default, so developers should be mindful of this if they add new RPC functionality. Fixes #2590.
2017-11-06track double spending in the txpoolmoneromooo-monero1-1/+2
Transactions in the txpool are marked when another transaction is seen double spending one or more of its inputs. This is then exposed wherever appropriate. Note that being marked with this "double spend seen" flag does NOT mean this transaction IS a double spend and will never be mined: it just means that the network has seen at least another transaction spending at least one of the same inputs, so care should be taken to wait for a few confirmations before acting upon that transaction (ie, mostly of use for merchants wanting to accept unconfirmed transactions).

2017-02-13blockchain_db: do not throw on expected partial results getting keysmoneromooo-monero3-3/+10
When scanning for outputs used in a set of incoming blocks, we expect that some of the inputs in their transactions will not be found in the blockchain, as they could be in previous blocks in that set. Those outputs will be scanned there at a later point. In this case, we add a flag to control wehther an output not being found is expected or not.
2017-02-11db_lmdb: fix bad height saved in tx datamoneromooo-monero2-6/+7
The recent change to not keep separate track of the blockchain height caused the reported height to jump early in the lmdb transaction (when the block data is added to the blocks table), rather than at the end, after everything succeeded. Since the block data is added before the transaction data, this caused the transaction data to be saved with a height one more than its expected value. Fix this by saving the block data last. This should have no side effects.

2017-01-16Change logging to easylogging++moneromooo-monero2-17/+24
This replaces the epee and data_loggers logging systems with a single one, and also adds filename:line and explicit severity levels. Categories may be defined, and logging severity set by category (or set of categories). epee style 0-4 log level maps to a sensible severity configuration. Log files now also rotate when reaching 100 MB. To select which logs to output, use the MONERO_LOGS environment variable, with a comma separated list of categories (globs are supported), with their requested severity level after a colon. If a log matches more than one such setting, the last one in the configuration string applies. A few examples: This one is (mostly) silent, only outputting fatal errors: MONERO_LOGS=*:FATAL This one is very verbose: MONERO_LOGS=*:TRACE This one is totally silent (logwise): MONERO_LOGS="" This one outputs all errors and warnings, except for the "verify" category, which prints just fatal errors (the verify category is used for logs about incoming transactions and blocks, and it is expected that some/many will fail to verify, hence we don't want the spam): MONERO_LOGS=*:WARNING,verify:FATAL Log levels are, in decreasing order of priority: FATAL, ERROR, WARNING, INFO, DEBUG, TRACE Subcategories may be added using prefixes and globs. This example will output net.p2p logs at the TRACE level, but all other net* logs only at INFO: MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE Logs which are intended for the user (which Monero was using a lot through epee, but really isn't a nice way to go things) should use the "global" category. There are a few helper macros for using this category, eg: MGINFO("this shows up by default") or MGINFO_RED("this is red"), to try to keep a similar look and feel for now. Existing epee log macros still exist, and map to the new log levels, but since they're used as a "user facing" UI element as much as a logging system, they often don't map well to log severities (ie, a log level 0 log may be an error, or may be something we want the user to see, such as an important info). In those cases, I tried to use the new macros. In other cases, I left the existing macros in. When modifying logs, it is probably best to switch to the new macros with explicit levels. The --log-level options and set_log commands now also accept category settings, in addition to the epee style log levels.

2016-09-18cmake: transitive deps and remove deprecated LINK_*redfish1-8/+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.
2016-08-31core: faster find_blockchain_supplementmoneromooo-monero5-5/+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.
2016-08-29db_lmdb: fix reorg with "halfway rct" coinbase outputsmoneromooo-monero1-1/+3
2016-08-28New "Halfway RingCT" outputs for coinbase transactionsmoneromooo-monero1-2/+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.
2016-08-28move the rct commitments to the output_amounts databasemoneromooo-monero6-167/+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.

2016-04-05Update schema for "tx_outputs" to use array containing amount output indiceswarptangent4-119/+131
This speeds up wallet refresh by directly retrieving a tx's amount output indices. 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.

2016-03-26New RPC and daemon command to get output histogrammoneromooo-monero5-0/+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.

When keys are contiguous and monotonically increasing, this gets denser page utilization (doesn't leave padding in page splits). Can't be used for keys that are inserted in random order (e.g. hashes) In total this only saves around 1.5% of space compared to original DB code. The previous patch accounted for 0.8% savings on its own; the blocks tables just aren't that big.

2015-12-24BlockchainDB: Remove txs in reverse orderwarptangent1-3/+5
Data should be removed in the reverse order it was added. Not doing so breaks assumptions and can cause problems in other DB implementations. This matches the order of tx removal in blockchain_storage::purge_block_data_from_blockchain.
2015-12-24BlockchainLMDB: When removing, find amount output index fast by starting at endwarptangent1-4/+5
This improves blockchain reorganization time by allowing one of the more expensive DB lookups when popping a block to not have to seek through a long dup list in the "output_amounts" subdb. This is most noticeable for HDDs. As before, the dup list is still walked if necessary (but in reverse), and the global output index still confirmed to be the one looked for. But under proper use, the result will be found at the end of the dup list, so we start there. Removing an amount output index is always done in the context of popping a block, so the global output index being looked for should be the last one in that amount key's dup list. Even if the txs themselves aren't removed in reverse order (supposed to be according to original implementation), the specified amount output index will still be near the end, because the txs are in the same block. TEST: Pop blocks with blockchain_import. Blocks should be successfully removed with no errors shown. bitmonerod should be able to start syncing from the reduced blockchain height.
