Howard Chu 38c2277d6f Use DUPFIXED for spent_keys 2016-04-05 20:54:07 +01:00
warptangent bf769c32ba Add back changes from revert. 
m_tx_outputs doesn't need to be changed, as it's no longer dup list.
 2016-04-05 20:54:07 +01:00
warptangent 46b991b362 Use MDB_APPEND mode with two tx subdbs 
This is possible on those using a tx index as a key.

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.

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.

Howard Chu f2faf8cdd9 Use MDB_APPEND mode where possible 
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.
