Instead of blindly using the `sighash_type` set in a psbt input, we
now only sign `SIGHASH_ALL` inputs by default, and require the user to
explicitly opt-in to using other sighashes if they desire to do so.
Fixes#350
Clippy emits:
warning: struct constructor field order is inconsistent with struct
definition field order
As suggested, re-order the fields to be consistent with the struct
definition.
It is redundant to pass true/false to `assert_eq!` since `assert!`
already asserts true/false.
This may, however, be controversial if someone thinks that
```
assert_eq!(foo, false);
```
is more clear than
```
assert!(!foo);
```
Use `assert!` directly instead of `assert_eq!` with true/false argument.
We recently converted uses of `PSBT` -> `Psbt` inline with idiomatic
Rust acronym identifiers. Do the same to `PSBTKey`.
Use `PsbtKey` instead of `PSBTKey` when aliasing the import of
`psbt::raw::Key` from `bitcoin` library.
Idiomatic Rust uses lowercase for acronyms for all characters after the
first e.g. `std::net::TcpStream`. PSBT (Partially Signed Bitcoin
Transaction) should be rendered `Psbt` in Rust code if we want to write
idiomatic Rust.
Use `Psbt` instead of `PSBT` when aliasing the import of
`PartiallySignedTransaction` from `bitcoin` library.
Instead of providing an opt-in option to force the addition of the
`non_witness_utxo`, we will now add them by default and provide the
option to disable them when they aren't considered necessary.
Adds fix for edge-cases involving small UTXOs (where value < fee) where the coin_select calculation would panic with overflow/underflow errors.
Bitcoin is limited to 21*(10^6), so any Bitcoin amount fits into i64.
To allow adding UTXOs external to the current wallet.
The caller must provide the psbt::Input so we can create a coherent PSBT
at the end and so this is compatible with existing PSBT workflows.
Main changes:
- There are now two types of UTXOs, local and foreign reflected in a
`Utxo` enum.
- `WeightedUtxo` now captures floating `(Utxo, usize)` tuples
- `CoinSelectionResult` now has methods on it for distinguishing between
local amount included vs total.
Currently we have a unit test to test that signers are sorted by
ordering. We call `add_external` to add them but currently we add them
in the same order we expect them to be in. This means if the
implementation happens to insert them simply in the order they are
added (i.e. insert to end of list) then this test will still pass.
Insert in a mixed order, including one lower followed by one higher -
this ensures we are not inserting at the front or at the back but are
actually sorting based on the `SignerOrdering`.
If we give the `DummySigner` a valid identifier then we can use this to
do comparison.
Half the time we do comparison we only have a `dyn Signer` so we cannot
use `PartialEq`, add a helper function to check equality (this is in
test code so its not toooo ugly).
Thanks @afilini for the suggestion.
