I used to be testing Bitcoin Core 31.0 to see if I may make chains of unconfirmed transactions longer than 25. Launch notes say:
The mempool not enforces ancestor or descendant measurement/depend limits. As an alternative, two new default coverage limits are launched governing linked parts, or clusters, within the mempool, limiting clusters to 64 transactions and as much as 101 kB in digital measurement. Transactions are thought of to be in the identical cluster if they’re linked to one another by way of any mixture of guardian/baby relationships within the mempool. These limits could be overridden utilizing command-line arguments; see the prolonged assist (-help-debug) for extra data.
Does this solely maintain for transactions being relayed to my node, and never for transactions my pockets creates? Does the pockets nonetheless implement the 25 txn restrict throughout a transition interval till the brand new mempool coverage is extra widespread?
The next script on a newly began Bitocoin Core 31.0 regtest node fails on the final command:
bitcoin-cli getnetworkinfo
bitcoin-cli createwallet miner
ADDR=`bitcoin-cli getnewaddress`
bitcoin-cli generatetoaddress 101 $ADDR
# 1 confirmed UTXO
for i in `seq 0 24`; do
bitcoin-cli sendtoaddress $ADDR 1
achieved
# We now have a series of 25 unconfirmed txs
# I anticipated including yet one more would work on bitcoin core 31.0
bitcoin-cli sendtoaddress $ADDR 1
Output appears to be like one thing like this:
{
"model": 310000,
"subversion": "/Satoshi:31.0.0/",
...

error code: -6
error message:
Unconfirmed UTXOs can be found, however spending them creates a series of transactions that will likely be rejected by the mempool
