featureDisallowIncoming is a new amendment that would allow users to opt-out of incoming Checks, Payment Channels, NFTokenOffers, and trust lines. This commit includes tests.
Adds four new AccountSet Flags:
1. asfDisallowIncomingNFTOffer
2. asfDisallowIncomingCheck
3. asfDisallowIncomingPayChan
4. asfDisallowIncomingTrustline
Reduce the reserve requirements from 20/5 to 10/2 in line with the current network votes. The requirements of 10/2 have been on the network long enough that new nodes should not still have the old reserve amount.

It turns out that the feature enabled by the tfTrustLine flag
on an NFTokenMint transaction could be used as a means to
attack the NFToken issuer. Details are in
https://github.com/XRPLF/rippled/issues/4300
The fixRemoveNFTokenAutoTrustLine amendment removes the
ability to set the tfTrustLine flag on an NFTokenMint
transaction.
Closes 4300.
The XLS-20 implementation contained two bugs that would require the
introduction of amendments. This complicates the adoption of XLS-20
by requiring a staggered amendment activation, first of the two fix
amendments, followed by the `NonFungibleTokensV1` amendment.
After consideration, the consensus among node operators is that the
process should be simplified by the introduction of a new amendment
that, if enabled, would behaves as if the `NonFungibleTokensV1` and
the two fix amendments (`fixNFTokenDirV1` and `fixNFTokenNegOffer`)
were activated at once.
This commit implements this proposal; it does not introduce any new
functionality or additional features, above and beyond that offered
by the existing amendments.
The existing code would, incorrectly, allow negative amounts in offers
for non-fungible tokens. Such offers would be handled very differently
depending on the context: a direct offer would fail with an error code
indicating an internal processing error, whereas brokered offers would
improperly succeed.
This commit introduces the `fixNFTokenNegOffer` amendment that detects
such offers during creation and returns an appropriate error code.
The commit also extends the existing code to allow for buy offers that
contain a `Destination` field, so that a specific broker can be set in
the offer.
A few unit tests have historically generated a lot of noise
to the console from log writes. This noise was not useful
and made it harder to locate actual test failures.
By changing the log level of these tests from
- severities::kError to
- severities::kDisabled
it was possible to remove that noise coming from the logs.
o Fixes an off-by-one when determining which NFTokenPage an
NFToken belongs on.
o Improves handling of packed sets of 32 NFTs with
identical low 96-bits.
o Fixes marker handling by the account_nfts RPC command.
o Tightens constraints of NFTokenPage invariant checks.
Adds unit tests to exercise the fixed cases as well as tests
for previously untested functionality.
The amendment increases the maximum sign of an account's signer
list from 8 to 32.
Like all new features, the associated amendment is configured with
a default vote of "no" and server operators will have to vote for
it explicitly if they believe it is useful.
* Txs with the same fee level will sort by TxID XORed with the parent
ledger hash.
* The TxQ is re-sorted after every ledger.
* Attempt to future-proof the TxQ tie breaking test
The pathfinding engine built into the code has several configurable
parameters to adjust the depth of the paths indexed and explored.
These parameters can dramatically impact the performance and memory
consumption of a server; higher values can result in resource usage
increasing exponentially.
These default values were decided early and somewhat arbitrarily at
a time when the network and the size of the network state were much
smaller.
This commit adjusts the default values to reduce the depth of paths
to more reasonable levels; unless explicitly overriden, the changes
mean that pathfinding operations will return fewer, shallower paths
than previous versions of the software.
* Sort by fee level (which is the current behavior) then by transaction
ID (hash).
* Edge case when the account at the end of the queue submits a higher
paying transaction to walk backwards and compare against the cheapest
transaction from a different account.
* Use std::if_any to simplify the JobQueue::isOverloaded loop.
The existing calculation would limit the maximum number of threads
that would be created by default to at most 6; this may have been
reasonable a few years ago, but given both the load on the network
as of today and the increase in the number of CPU cores, the value
should be revisited.
This commit, if merged, changes the default calculation for nodes
that are configured as `large` or `huge` to allow for up to twelve
threads.
