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.
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.
Unconfirmed transactions that are not in your mempool either due to eviction or other means may be unlikely to be mined. abandontransaction gives the wallet a way to no longer consider as spent the coins that are inputs to such a transaction. All dependent transactions in the wallet will also be marked as abandoned.
Due to include ordering, defining in one place was not enough to ensure correct
usage. Use global defines so that we don't have to worry abou this ordering.
Also add a comment in configure about the test.
This is ugly, but temporary. boost::filesystem will likely be dropped soon
after c++11 is enabled. Otherwise, we could simply roll our own copy_file. I've
fixed this at the buildsystem level for now in order to avoid mixing in
functional changes.
Explanation:
If boost (prior to 1.57) was built without c++11, it emulated scoped enums
using c++98 constructs. Unfortunately, this implementation detail leaked into
the abi. This was fixed in 1.57.
When building against that installed version using c++11, the headers pick up
on the native c++11 scoped enum support and enable it, however it will fail to
link. This can be worked around by disabling c++11 scoped enums if linking will
fail.
Add an autoconf test to determine incompatibility. At build-time, if native
enums are being used (a c++11 build), and force-disabling them causes a
successful link, we can be sure that there's an incompatibility and enable the
work-around.
Don't scan the wallet to see if the current key has been used if we're going to make a new key anyway.
Stop scanning the wallet as soon as we see that the current key has been used.
Don't call isValid() twice on the current key.
CWalletTx::GetAmounts could not find output address for null data transactions, thus issuing an error in debug.log. This change checks to see if the transaction is OP_RETURN before issuing error.
resolves#6142
A further pass over the available inputs has been added to ApproximateBestSubset after a candidate set has been found. It will prune any extraneous inputs in the selected subset, in order to decrease the number of input and the resulting change.
This allows for much finer control of the transaction fees per kilobyte
as it prevent small transactions using a fee that is more appropriate
for one that is of a kilobyte.
This also allows controlling the fee per kilobyte over rpc such that:
bitcoin-cli settxfee `bitcoin-cli estimatefee 2`
would make sense, while currently it grossly fails often by a factor of x3
