2022-04-18Add view tags to outputs to reduce wallet scanning timej-berman1-3/+4
Implements view tags as proposed by @UkoeHB in MRL issue https://github.com/monero-project/research-lab/issues/73 At tx construction, the sender adds a 1-byte view tag to each output. The view tag is derived from the sender-receiver shared secret. When scanning for outputs, the receiver can check the view tag for a match, in order to reduce scanning time. When the view tag does not match, the wallet avoids the more expensive EC operations when deriving the output public key using the shared secret.

2021-02-09Remove unused variables in monero codebaseKevin Barbour1-11/+4
There are quite a few variables in the code that are no longer (or perhaps never were) in use. These were discovered by enabling compiler warnings for unused variables and cleaning them up. In most cases where the unused variables were the result of a function call the call was left but the variable assignment removed, unless it was obvious that it was a simple getter with no side effects.

2019-09-27monerod can now sync from pruned blocksmoneromooo-monero1-2/+4
If the peer (whether pruned or not itself) supports sending pruned blocks to syncing nodes, the pruned version will be sent along with the hash of the pruned data and the block weight. The original tx hashes can be reconstructed from the pruned txes and theur prunable data hash. Those hashes and the block weights are hashes and checked against the set of precompiled hashes, ensuring the data we received is the original data. It is currently not possible to use this system when not using the set of precompiled hashes, since block weights can not otherwise be checked for validity. This is off by default for now, and is enabled by --sync-pruned-blocks

85088d9f db_lmdb: fix missing mdb_dbi_close in migration (moneromooo-monero)
2019-03-04ArticMine's new block weight algorithmmoneromooo-monero2-6/+214
This curbs runaway growth while still allowing substantial spikes in block weight Original specification from ArticMine: here is the scaling proposal Define: LongTermBlockWeight Before fork: LongTermBlockWeight = BlockWeight At or after fork: LongTermBlockWeight = min(BlockWeight, 1.4*LongTermEffectiveMedianBlockWeight) Note: To avoid possible consensus issues over rounding the LongTermBlockWeight for a given block should be calculated to the nearest byte, and stored as a integer in the block itself. The stored LongTermBlockWeight is then used for future calculations of the LongTermEffectiveMedianBlockWeight and not recalculated each time. Define: LongTermEffectiveMedianBlockWeight LongTermEffectiveMedianBlockWeight = max(300000, MedianOverPrevious100000Blocks(LongTermBlockWeight)) Change Definition of EffectiveMedianBlockWeight From (current definition) EffectiveMedianBlockWeight = max(300000, MedianOverPrevious100Blocks(BlockWeight)) To (proposed definition) EffectiveMedianBlockWeight = min(max(300000, MedianOverPrevious100Blocks(BlockWeight)), 50*LongTermEffectiveMedianBlockWeight) Notes: 1) There are no other changes to the existing penalty formula, median calculation, fees etc. 2) There is the requirement to store the LongTermBlockWeight of a block unencrypted in the block itself. This is to avoid possible consensus issues over rounding and also to prevent the calculations from becoming unwieldy as we move away from the fork. 3) When the EffectiveMedianBlockWeight cap is reached it is still possible to mine blocks up to 2x the EffectiveMedianBlockWeight by paying the corresponding penalty. Note: the long term block weight is stored in the database, but not in the actual block itself, since it requires recalculating anyway for verification.

2019-01-22Pruningmoneromooo-monero2-23/+405
The blockchain prunes seven eighths of prunable tx data. This saves about two thirds of the blockchain size, while keeping the node useful as a sync source for an eighth of the blockchain. No other data is currently pruned. There are three ways to prune a blockchain: - run monerod with --prune-blockchain - run "prune_blockchain" in the monerod console - run the monero-blockchain-prune utility The first two will prune in place. Due to how LMDB works, this will not reduce the blockchain size on disk. Instead, it will mark parts of the file as free, so that future data will use that free space, causing the file to not grow until free space grows scarce. The third way will create a second database, a pruned copy of the original one. Since this is a new file, this one will be smaller than the original one. Once the database is pruned, it will stay pruned as it syncs. That is, there is no need to use --prune-blockchain again, etc.

008647d7 blockchain_db: speedup tx output gathering (moneromooo-monero)
2019-01-07Make get_output_key method constmoneroexamples2-4/+4
get_output_key method is commonly used when working with txs and their key images. Because the method is not const, passing blockchain object though const& or pointers to const is not possible in this context. This is especially problematic in external projects (e.g., projects in moneroexamples) that use monero C++ api to operate on the blockchain and txs. Thus, having get_output_key method will simplify moving blockchain object around through const references and pointers to const objects.

Only for pre rct for obvious reasons. Note: DO NOT use a known spent list which includes outputs which are not known spent. If the list includes any output that's just strongly thought to be spent, but not provably so, you risk finding yourself unable to sync past the point where that output is spent. I estimate only 200 MB saved on current mainnet though, unless the new blackballing rule unearths a good amount of large-amount-set extra spent outs.

2017-11-08Protect node privacy by proper filtering in restricted-mode RPC answersbinaryFate2-9/+40
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.

2017-02-13blockchain_db: do not throw on expected partial results getting keysmoneromooo-monero2-2/+9
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-monero1-0/+1
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.

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.

2016-08-31core: faster find_blockchain_supplementmoneromooo-monero2-2/+9
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.

2016-08-28move the rct commitments to the output_amounts databasemoneromooo-monero2-128/+53
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.
