Instead of assigning a privacy segment at connect, wait until we have
determined if this peer is on the same chain as us before we allocate a
peer slot.
This also helps us limit the amount of peers we send our bloom filter to.
as the expected behavior of 'get*' is a const method, it is harmful to
name a method such when it actually alters the state of the method such
that subsequent calls will produce a different result.
This does remove the feature that mining can use the internal wallet as
a source of coinbase addresses, but since Flowee doesn't actually ship a
wallet, that was just not a good reason to keep an unused class in the
libs.
The CAmount name is not helpful as its just an int64_t and not a
class, like the name implies. There were a handful of places where
it was passed in as const-ref, as a good example of this actually
creating sub-par code.
The method offsetInBlock assumes the block actually is the one this
transaction is in, the assert helps making sure that this assumption
isn't broken, prodicing unusable results.
Move the MutableTransactionSignatureChecker class out of the header and
thereby remove the need to include transaction.h in the header.
This checker was never used in any app, just in the unit tests.
This also fixes includes around.
Especially seen in the block-validation tests, we sometimes delete
the validation engine while some other threads are still doing stuff
with the not surprising effect that we may cause crashes or asserts
to get hit.
This change makes us wait instead.
Summary:
CMerkleBlock::CMerkleBlock called IsRelevantAndUpdate() on each transaction
in order, which (due to the outpoint-adding feature) assumes a topological
order of transactions in order to work correctly. If an outpoint of
interest were created later in a block than when gets spent, then it would
be added into the bloom filter too late, and thus that spending transaction
would get missed.
This changes CMerkleBlock::CMerkleBlock to scan all outputs first, then
make a second loop to scan all inputs. This requires breaking up the
IsRelevantAndUpdate() function into two parts. The original
IsRelevantAndUpdate() functionality remains fully intact however, as it
gets called from mempool-related code (mempool has topological order) and
tests.
Note that vMatchedTxn.push_back is moved into the second loop so that index
i keeps ascending order, in case that is somehow relevant. (the tests at
least do check this)
A two-loop construction like this will very slightly increase the false
positive rate.
