5d388eb Bump ring size to 16 for v15 & remove set default in wallet cli (j-berman)
|

|
|
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.

This comment suggests this check is unnecessary, when it is completely necessary as miner TXs can have multiple outputs *which is a statement directly, and incorrectly, contradicted by this comment*. While I don't ever see someone removing this code and getting their edits merged into Monero, someone inexperienced who thinks they're cleaning old code may break their own work, and then there's really just zero benefit to keeping this around.

dfee15e RPC and ZeroMQ APIs to support p2pool (SChernykh)
|
|
Adds the following:
- "get_miner_data" to RPC API
- "json-miner-data" to ZeroMQ subscriber contexts
Both provide the necessary data to create a custom block template. They are used by p2pool.
Data provided:
- major fork version
- current height
- previous block id
- RandomX seed hash
- network difficulty
- median block weight
- coins mined by the network so far
- mineable mempool transactions

It only needs to parse the tx headers, not the full tx data
|
|
On Mac, size_t is a distinct type from uint64_t, and some
types (in wallet cache as well as cold/hot wallet transfer
data) use pairs/containers with size_t as fields. Mac would
save those as full size, while other platforms would save
them as varints. Might apply to other platforms where the
types are distinct.
There's a nasty hack for backward compatibility, which can
go after a couple forks.

bd12984 Remove copies from foreach loops (thanks to Clang) (Lee Clagett)
1572df9 Removing unused namespace alias (Lee Clagett)
|
|
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.

a25bc71 Make Blockchain::get_fee_quantization_mask() compile time (SChernykh)
|
|
|
|
A 20% fluff probability increases the precision of a spy connected to
every node by 10% on average, compared to a network using 0% fluff
probability. The current value (10% fluff) should increase precision by
~5% compared to baseline.
This decreases the expected stem length from 10 to 5. The embargo
timeout was therefore lowered to 39s; the fifth node in a stem is
expected to have a 90% chance of being the first to timeout, which is
the same probability we currently have with an expected stem length of
10 nodes.

|
|
|
This is already done

This also removes potential thread safety bug in that function.

a12a8174e Dandelion++: skip desynced peers in stem phase (xiphon)
|
|
Miners with MLSAG txes which they'd already verified included
a couple in that block, but the consensus rules had changed
in the meantime, so that block is technically invalid and any
node which did not already have those two txes in their txpool
could not sync. Grandfather them in, since it has no effect in
practice.

|
|
This fixes the functional tests, since txes would not be mined
after being sent to the daemon (they'd be waiting for the
dandelion timeout first)
|
|
The cache is discarded when a block is popped, but then gets
rebuilt when the difficulty for next block is requested.
While this is all properly locked, it does not take into account
the delay caused by a database transaction being only committed
(and thus its effects made visible to other threads) later on,
which means another thread could request difficulty between
the pop and the commit, which would end up using stale database
view to build the cache, but that cache would not be invalidated
again when the transaction gets committed, which would cause the
cache to not match the new database data.
To fix this, we now keep track of when the cache is invalidated
so we can invalidate it again upon database transaction commit
to ensure it gets calculated again with fresh data next time it
is nedeed.

It was using the raw block weight median, which was not what was

|
|
In case of a 0 tx weight, we use a placeholder value to insert in the
fee-per-byte set. This is used for pruning and mining, and those txes
are pruned, so will not be too large, nor added to the block template
if mining, so this is safe.

Use the lesser of the short and long terms medians, rather then
the long term median alone
From ArticMine:
I found a bug in the new fee calculation formula with using only the long term median
It actually needs to be the lesser of the long term median and the old (modified short term median)
short term median with the last 10 blocks calculated as empty
Yes the issue occurs if there is a large long term median and, the short term median then falls and tries to then rise again
The fees are could be not high enough
for example LTM and STM rise to say 2000000 bytes
STM falls back to 300000 bytes
Fees are now based on 2000000 bytes until LTM also falls
So the STM is could prevented from rising back up
STM short term median LTM long term median

|
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
