moneromooo-monero	eb56d0f994	blockchain_db: add functions for adding/removing/getting rct commitments	8 years ago
moneromooo-monero	f88029e72a	db_lmdb: do not try to modify the database in read only mode	8 years ago
Riccardo Spagni	0faf572db8	Merge pull request #948 ... 11dc091 Fake outs set is now decided by the wallet (moneromooo-monero) 1593553 new unlocked parameter to output_histogram (moneromooo-monero)	8 years ago
moneromooo-monero	240864f529	db_lmdb: errors dropping hf starting height db on reset are not fatal ... This db is now dropped unconditionally, so may or may not be there in the first place.	8 years ago
moneromooo-monero	1593553e03	new unlocked parameter to output_histogram ... 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).	8 years ago
moneromooo-monero	121165f222	db_lmdb: add some missing api call checks	8 years ago
moneromooo-monero	d7b681cd65	remove hf_starting_height db ... It's not really needed, it used to be an optimization for when that code was not using the db and needed to recalculate things fast on startup.	8 years ago
Howard Chu	2b0fa05f0d	Another take on migration ... Delete old indices and recreate them, rather than updating them Maybe not quite as slow as before.	8 years ago
Howard Chu	c14f9efd52	Migration ... Migrate from DB version 0 to version 1 on startup	8 years ago
Howard Chu	d7ea7d9a23	Merge branch 'performance' into master	8 years ago
Howard Chu	372acee723	Cleanup ... drop obsolete remove_output() fix get_output_key(global), fix crash in blockchain_dump	8 years ago
Howard Chu	591e421875	Cleanup and clarify ... Try to rationalize the variable names, document usage.	8 years ago
Howard Chu	b2f1c58805	Use cursors in some remove functions ... Helps when they're called repeatedly in one txn	8 years ago
Howard Chu	118dd69dd5	Use DUPFIXED for block_info and output_txs ... Saves another ~150MB or so on the full blockchain	8 years ago
Howard Chu	6225716f3c	More outputs consolidation ... Also bumped DB VERSION to 1 Another significant speedup and space savings: Get rid of global_output_indices, remove indirection from output to keys This is the change warptangent described on irc but never got to finish.	8 years ago
Howard Chu	7c5abdc3a3	Use DUPFIXED for output_keys ... Saves another 90MB on 200000 block import. Had to bring back compare_uint64 for this, but it's safe since this table is always 64-bit aligned.	8 years ago
Howard Chu	8e9d8e3364	Use DUPFIXED for tx_indices ... Small space savings, no measurable speedup	8 years ago
Howard Chu	a12f9365f8	Use DUPFIXED for block_heights ... Only a small savings...	8 years ago
Howard Chu	38c2277d6f	Use DUPFIXED for spent_keys	8 years ago
warptangent	bf769c32ba	Add back changes from revert. ... m_tx_outputs doesn't need to be changed, as it's no longer dup list.	8 years ago
warptangent	46b991b362	Use MDB_APPEND mode with two tx subdbs ... This is possible on those using a tx index as a key.	8 years ago
warptangent	9aadedb1d0	Schema update: tx_indices - consolidate the tx subdbs from 5 to 3	8 years ago
warptangent	a2f518aa01	Schema update: tx_indices - yet less indirection	8 years ago
warptangent	8d12a8df2c	Schema update: tx_indices - improve further with less indirection	8 years ago
warptangent	7c013f66e9	Add batch warning for further review	8 years ago

Howard Chu	8d252a4214	Consolidated block info	8 years ago
warptangent	132c666f67	Update schema for "tx_outputs" to use array containing amount output indices ... 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.

Howard Chu	efbdde2c66	Detect map resize failures	8 years ago
moneromooo-monero	600a3cf0c0	New RPC and daemon command to get output histogram ... 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.	8 years ago

Howard Chu	db1b2db4d5	Reduce log noise	8 years ago
Howard Chu	a74348e115	Add destructor for readtxns ... Only if we created the readtxn. Was missing cleanups from exceptions before.	8 years ago
Howard Chu	6b0a903177	Small cleanups ... Only one return and TXN_POSTFIX_RDONLY() per function Only log rtxn_start if the rtxn wasn't already active	8 years ago
Howard Chu	01c1512f22	More for 92dd4ec6d6 ... Make sure we stop the right txn too	8 years ago

Howard Chu	92dd4ec6d6	Hack for read/write txn mixup ... save the thread ID of the writer thread so we don't try to use the writetxn from reader threads	8 years ago

Howard Chu	f5affbef26	More for df239428c0 ... Let ARMv7 work again	8 years ago
warptangent	2c823c1589	Make partial revert consistent ... If user-defined comparator is used, subdb shouldn't be opened with MDB_INTEGERKEY. TODO: Again, this will be added back with future schema updates.	8 years ago
