If number of conflict confirms cannot be determined, this means
that the block is still unknown or not yet part of the main chain,
for example during a reindex. Do nothing in that case,
instead of crash with an assertion.
Fixes#7234.
This test is no longer relevant.
It was introduced in 8c222dca4f to check
the switch to 1MB blocks after the BDB too-many-locks issue back in
2013. The switching code has been long since removed.
It also needs a specific data file that is hard to find. I've verified
in #6320 that it still passes, however I think there is zero reason to
keep it.
Closes#6320.
A WWW-Authenticate header must be present in the 401
response to make clients know that they can authenticate,
and how.
WWW-Authenticate: Basic realm="jsonrpc"
Fixes#7462.
ProcessNewBlock would return failure early if CheckBlock failed, before
calling AcceptBlock. AcceptBlock also calls CheckBlock, and upon failure
would update mapBlockIndex to indicate that a block was failed. By returning
early in ProcessNewBlock, we were not marking blocks that fail a check in
CheckBlock as permanently failed, and thus would continue to re-request and
reprocess them.
This corrects a bug the case of tying group size where the code may
fail to select the group with the newest member. Since newest time
is the final selection criteria, failing to break ties on it
on the step before can undermine the final selection.
Tied netgroups are very common.

With automatic tor HS support in place we should probably not be providing
absolute protection for local peers, since HS inbound could be used to
attack pretty easily. Instead, this counts on the latency metric inside
AttemptToEvictConnection to privilege actually local peers.

Previously didn't make clear that the ContextualCheckBlock* functions
meant the block headers as context - not the UTXO set itself - and that
ConnectBlock() also did UTXO-related validity checks (in the future we
may split that functionality into a separate UTXO-specific contextual
check block function).
Also, reordered to put validity checks first for better readability.
Also renames whitelistalwaysrelay.
Nodes relay all transactions from whitelisted peers, this
gets in the way of some useful reasons for whitelisting
peers-- for example, bypassing bandwidth limitations.
The purpose of this forced relaying is for specialized gateway
applications where a node is being used as a P2P connection
filter and multiplexer, but where you don't want it getting
in the way of (re-)broadcast.
This change makes it configurable with whitelistforcerelay.
"permit" is currently used to configure transaction filtering, whereas replacement is more to do with the memory pool state than the transaction itself.
Adds several unittests for CAddrMan and CAddrInfo.
Increases the accuracy of addrman tests.
Removes non-determinism in tests by overriding the random number generator.
Extracts testing code from addrman class to test class.
Add a configuration option `-permitrbf` to set transaction replacement policy
for the mempool.
Enabling it will enable (opt-in) RBF, disabling it will refuse all
conflicting transactions.
Add "bip125-replaceable" output field to listtransactions and gettransaction
which indicates if an unconfirmed transaction, or any unconfirmed parent, is
signaling opt-in RBF according to BIP 125.
