Filtering `AvailableCoins` by spendable outputs only and using the retrieved total_amount.
|
|
We are skipping the non-spendable coins that appear in vCoins ('AvailableCoins' result) later, in several parts of the CreateTransaction and GetBalance flows:
GetAvailableBalance (1) gets all the available coins calling AvailableCoins and, right away, walk through the entire vector, skipping the non-spendable coins, to calculate the total balance.
Inside CreateTransactionInternal —> SelectCoins(vCoins,...), we have several calls to AttemptSelection which, on each of them internally, we call twice to GroupOutputs which internally has two for-loops over the entire vCoins vector that skip the non-spendable coins.
So, Purpose is not add the non-spendable coins into the AvailableCoins result (vCoins) in the first place for the processes that aren’t using them at all, so we don’t waste resources skipping them later so many times.
Note: this speedup is for all the processes that call to CreateTransaction and GetBalance* internally.

Instead of accepting a `vCoins` reference that is cleared at the beginning of the method.
Note:
This new struct, down the commits line, will contain other `AvailableCoins` useful results.

Previously in COutput, effective_value was initialized as the absolute
value of the txout, and fee as 0. effective_value along with fee were
calculated outside of the COutput constructor and set after the
object had been initialized. These changes will allow either the fee
or the feerate to be passed in a COutput constructor. If either are
provided, fee and effective_value are calculated and set in the
constructor. As a result, AvailableCoins also needs to be passed the
feerate when utxos are being spent. When balance is calculated or the
coins are being listed and feerate is neither available nor required,
AvailableCoinsListUnspent is used instead, which runs AvailableCoins
while providing the default value for feerate. Unit tests for the
calculation of effective value have also been added.

Instead of having a pointer to the CWalletTx in COutput, we can just
store the COutPoint and the CTxOut as those are the only things we need
from the CWalletTx. Other things CWalletTx used to provide were time and
fIsFromMe but these are also being stored by COutput.

|
|
Instead of determining whether the containing transaction is from the
wallet dynamically as needed, just pass it in to COutput and store it.
The transaction ownership isn't going to change.

|
|
|
As we change the constructor for COutput, it becomes somewhat dangerous
if there are default values.

Update the member variables to match the new style

d09071da5bc997f2de1f55ca7a9babc3d7619329 [MOVEONLY] consensus: move amount.h into consensus (fanquake)
Pull request description:
A first step (of a few) towards some source code reorganization, as well as making libbitcoinconsensus slightly more self contained.
Related to #15732.

Move amount.h to consensus/amount.h.
Renames, adds missing and removes uneeded includes.

Followup to commit "MOVEONLY: CWallet transaction code out of
wallet.cpp/.h" that detaches and renames some CWalletTx methods, making
into them into standalone functions or CWallet methods instead.
There are no changes in behavior and no code changes that aren't purely
mechanical. It just gives spend and receive functions more consistent
names and removes the circular dependencies added by the earlier
MOVEONLY commit.
There are also no comment or documentation changes. Removed comments
from transaction.h are just migrated to spend.h, receive.h, and
wallet.h.

This commit just moves functions without making any changes. It can be
reviewed with `git log -p -n1 --color-moved=dimmed_zebra`
Motivation for this change is to make wallet.cpp/h less monolithic and
start to make wallet transaction state tracking comprehensible so bugs
in
https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking
can be fixed safely without introducing new problems.
This commit moves wallet classes and methods that deal with transactions
out of wallet.cpp/.h into better organized files:
- transaction.cpp/.h - CWalletTx and CMerkleTx class definitions
- receive.cpp/.h - functions checking received transactions and computing balances
- spend.cpp/.h - functions creating transactions and finding spendable coins
After #20773, when loading is separated from syncing it will also be
possible to move more wallet.cpp/.h functions to:
- sync.cpp/.h - functions handling chain notifications and rescanning
This commit arranges receive.cpp and spend.cpp functions in dependency
order so it's possible to skim receive.cpp and get an idea of how
computing balances works, and skim spend.cpp and get an idea of how
transactions are created, without having to jump all over wallet.cpp
where functions are not in order and there is a lot of unrelated code.
Followup commit "refactor: Detach wallet transaction methods" in
https://github.com/bitcoin/bitcoin/pull/21206 follows up this PR and
tweaks function names and arguments to reflect new locations. The two
commits are split into separate PRs because this commit is more work to
maintain and less work to review, while the other commit is less work to
maintain and more work to review, so hopefully this commit can be merged
earlier.
