Accept flexible input types for Taproot-related functions
Refactor Taproot functions to accept any type implementing `Into<XOnlyPublicKey>`,
instead of requiring `XOnlyPublicKey` directly. This improves ergonomics when working
with compatible types, avoiding unnecessary `.into()` conversions at call sites.

yancy 13cbead947 Use NumOpResult instead of Option
Prefer the more descriptive NumOpResult return type over Option where
return types are fallible.

The returned type NumOpResult is already annotated as must_use per the
lint, so must_use can be removed after changing the method return types
to NumOpResult.

Pull request description:

  This PR does a whole bunch of renames to the `units` locktime modules. These modules contain the underlying units for locktime types and hopefully aren't used directly too often, which should minimize the disruption from these renames.

  This fixes a number of issues:

  * Confusion between blocktimes and MTPs (which in fairness, *are* blocktimes, but they're not the one that users are likely to reach for)
  * Constructor and conversion names that imply there is a "consensus encoding" for these bare units, which corresponded to the consensus encoding of the corresponding locktimes/sequence numbers
  * `from_*` methods without `to_*` methods and vice-versa (overlaps with the above)
  * the horribly named `value` method on relative heights and times (but not absolute ones)

  This PR does **not** remove the `MtpAndHeight` type, nor does it add constructors for `Mtp` from lists of blocktimes. This is because the PR was too big already and I felt I should split it up.

  Alternate to #4427

units: rename relative::Height to HeightInterval
This is disruptive, but makes the type name consistent with
`MtpInterval` and also greatly improves clarity, helping to distinguish
between absolute and relative locktimes and reminding the author (and
reviewer) of locktime code that this needs to be a diff.

units: rename relative::Time to MtpInterval
The name `Time` is misleading. In fact this represents an interval
between MTPs.

Andrew Poelstra 8ffcd2cf30
units: rename absolute::Time to absolute::Mtp
This is not a generic UNIX timestamp, but rather a MTP restricted to
have values between 500 million and u32::MAX. Most importantly, it is
*not* a blocktime, which is what is implied by its name and
constructors.

Make script to/from hex use consensus encoding
I'm not sure why we do not use consensus encoding currently for encoding
and decoding scripts to/from hex strings. Many tests include hard coded
hex which do not include the length prefix.

- Add a pair of encoding functions to encode/decode to/from hex without
the length prefix.
- Make `to_hex` and `from_hex` expect the length prefix i.e., use
consensus encoding.

This makes the API easier to use because the various encoding APIs can
be use together now eg `consensus::encode_hex` and `ScriptBuf::from_hex`.

Merge rust-bitcoin/rust-bitcoin#4302: Add push_relative_lock_time() and deprecate push_sequence()

Pull request description:

  This pr improves the script builder API to better align with Bitcoin semantics when working with relative timelocks:

  - Add `push_relative_lock_time()` method that takes a `relative::LockTime` parameter, which correctly represents the semantic meaning when working with CHECKSEQUENCEVERIFY

  - Deprecate `push_sequence()` in favor of `push_relative_lock_time()` to avoid confusion between sequence numbers and relative timelocks

  This addresses a potential confusion point in the API where developers might incorrectly push raw sequence numbers in scripts when what they actually need is to push a relative locktime value that will be checked against the transaction's sequence numbers by CHECKSEQUENCEVERIFY.

  Well, I thought this PR will be just the last commit... 😅

  Anyway, this implements a bunch of changes to allow returning `ControlBlock` from `Witness` method(s). One cool side effect is that this PR also reduces the number of `unsafe` blocks.

Martin Habovstiak 492073f288 Strengthen the type of `taproot_control_block()`
The type returned by `Witness::taproot_control_block()` was just `&[u8]`
which wasn't very nice since users then had to manually decode it which
so far also required allocation. Thanks to previous improvements to
`ControlBlock` it is now possible to return a `ControlBlock` type
directly.

To avoid expensive checks, this change adds a new type
`SerializedXOnlyPublicKey` which is a wrapper around `[u8; 32]` that is
used in `ControlBlock` if complete checking is undesirable. It is then
used in the `ControlBlock` returned from
`Witness::taproot_control_block`. Users can still conveniently validate
the key using `to_validated` method.

It then uses this type in the recently-added `P2TrSpend` type. As a side
effect this checks more properties of `Witness` when calling unrelated
methods on `Witness`. From correctness perspective this should be OK: a
witness obtained from a verified source will be correct anyway and, if
these checks were done by the caller, they can be removed.

From performance perspective, if the `Witness` was obtained from a
verified source (e.g. using Bitcoin Core RPC) these checks are wasted
CPU time. But they shouldn't be too expensive, we already avoid
`secp256k1` overhead and, given that they always succeed in such case,
they should be easy to branch-predict.

Martin Habovstiak e8a42d5851 Unify/reduce usage of `unsafe`
Since the introduction of `Script` `unsafe` started slowly creeping in
as more types with similar semantics were added. The `unsafe` in these
cases is just for trivial conversions between various pointer-like
types. As such, it's possible to move these into a single macro that
takes care of the conversions at one place and avoid repeating the same
`unsafe` code in the codebase. This decreases the cost of audits which
now only need to happen in `internals`, focuses any changes to happen in
that single macro and decreases the chance that we will mess up
similarly to the recent `try_into().expect()` issue (but this time with
UB rather than panic).

The new macro accepts syntax very similar to the already-existing struct
declarations with these differences:

* The struct MUST NOT have `#[repr(transparent)]` - it's added by the
  macro
* If the struct uses `PhantomData` it must be the first field and the
  real data must be the second field (to allow unsized types).
* The struct must be immediately followed by an impl block containing at
  least on conversion function.
* If the struct has generics the impl block has to use the same names of
  generics.
* The conversion functions don't have bodies (similarly to required
  trait methods) and have a fixed set of allowed signatures.
* Underscore (`_`) must be used in place of the inner type in the
  conversion function parameters.

The existing code can simply call the macro with simple changes and get
the same behavior without any direct use of `unsafe`. This change
already calls the macro for all relevant existing types. There are still
some usages left unrelated to the macro, except one additional
conversion in reverse direction on `Script`. It could be moved as well
but since it's on a single place so far it's not really required.

Martin Habovstiak 84bee2f7b0 Simplify `Witness` construction in tests
The `Witness`-related tests were constructing `Witness` in
over-complicated way by serializing `Vec<Vec<u8>>` and then
deserializing `Witness` even though they were not supposed to test
serialization but Taproot accessor methods. This was difficult to
understand and maintain.

This change simplifies them to just construct the `Witness` from array
of `Vec<u8>`s using the recently-added constructors. Note that we
already have serialization tests written separately so we're not losing
meaningful coverage here.

Pull request description:

  This implements a bunch of changes needed to make `ControlBlock` alloc-free. In particular, this allows constructing `Witness` without the intermediate allocation. It is also a step towards having `P2TrSpend` public.

  Closes #1614

  This also intentionally does **not** address decoding of `ControlBlock` from `Witness` since I'm not sure about the API.

  Rationale for doing the `Buf` rename: while doing it with `Script` was very painful it shouldn't be here since it's not used that often and also we can just backport the first commit with deprecated type alias. I was thinking of having `TaprootMerkleBr` but it'd be inconsistent and the name is silly.

  (Also if anyone is wondering why I did this: I was too exhausted to do more important stuff but felt like doing something nice and easy like this.)

amount: add from_sat_i32 and from_sat_u32 methods for small constants
We have a ton of calls to `from_sat_unchecked` for small constants which
were clearly in range, e.g. in fee.rs. Add a new constfn for these
cases. Don't bother making a generic Into<u32>/Into<u16> variant because
there isn't an obvious name for it.

There are 7 instances where we're using this method with values that are
out of range, which we leave as from_sat_unchecked for now.

Martin Habovstiak 04a4efbe63 Introduce unsized `TaprootMerkleBranch`
`TaprootMerkleBranchBuf` being a vec introduced intermediate allocation
when creating or decoding `Witness`. However the representation on the
wire is the same as in-memory (aside from `#[repr(transparent)]`) so
this allocation wasn't really needed.

This commit introduces `TaprootMerkleBranch` type which is unsized and
can be used in place of `TaprootMerkleBranchBuf` within `ControlBlock`.
Aside from removing the intermediate allocation, this improves the API a
bit: the conversion from array to other type is no longer needed because
it's performed by `ControlBlock` in its methods. Thus, consumers who
have an array can simply set it as `merkle_branch` field and then encode
the `ControlBlock` into witness. A convenience method is also provided
to push the `ControlBlock` along with other parts at the end of the
`Witness`.

  I originally thought it would be better to use this value for checking limit of push_bytes [here](0870cd1660/bitcoin/src/blockdata/script/push_bytes.rs (L31)), as it's the actual limit(`OP_PUSHDATA4` semantic says it could allow up to 4GB though). However, I'm not sure whether there might be need to push_bytes larger than `MAX_BLOCK_SERIALIZED_SIZE`, so just let developer use this constant to check the actual limit rather than enforcing it.

  Fixes #4097

  High priority because it blocks a bunch of work and should be probably swiftly backported.

  My plan is to backport this entire PR and then in the breaking version remove the broken `tapscript` method entirely. Keeping it around would be way too confusing if we're going to have tagged script.

Add Timestamp newtype
Bitcoin block headers have a timestamp. Currently we are using a
`u32`. while this functions correctly it gives the compiler no chance
to enforce type safety.

Add a `Timestamp` newtype that is a thin wrapper around a `u32`.
Document it and test the API surface in `api.rs`.

Martin Habovstiak a8168c3f81 Add `taproot_leaf_script` methood to `Witness`
We already have `tapscript` method on `Witness` which is broken because
it doesn't check that the leaf script is a tapscript, however that
behavior might have been intended by some consumers who want to inspect
the script independent of the version. To resolve the confusion, we're
going to add a new method that returns both the leaf script and, to
avoid forgetting version check, also the leaf version.

This doesn't touch the `tapscript` method yet to make backporting of
this commit easier. It's also worth noting that leaf script is often
used together with version. To make passing them around easier it'd be
helpful to use a separate type. Thus this also adds a public POD type
containing the script and the version. In anticipation of if being
usable in different APIs it's also generic over the script type.
Similarly to the `tapscript` method, this also only adds the type and
doesn't change other functions to use it yet. Only the newly added
`taproot_leaf_script` method uses it now.

This is a part of #4073

Martin Habovstiak 59f21a291f Add a test case checking `taproot_control_block`
The previous commit fixed a bug when `taproot_control_block` returned
`Some` on key-spends. This adds a test case for it which succeeds when
applied after the previous commit and fails if applied before it.
2025-02-24 18:33:31 +01:00
Martin Habovstiak e810ecff7c Fix key/script spend detection in `Witness`
The `taproot_control_block` did not properly detect whether it deals
with script spend or key spend. As a result, if key spend with annex was
used it'd return the first element (the signature) as if it was a
control block.

Further, the conditions identifying which kind of spend it was were
repeated multiple times but behaved subtly differently making only
`taproot_control_block` buggy but the other places confusing.

To resolve these issues this change adds a `P2TrSpend` enum that
represents a parsed witness and has a single method doing all the
parsing. The other methods can then be trivially implemented by matching
on that type. This way only one place needs to be verified and the
parsing code is more readable since it uses one big `match` to handle
all possibilities.

The downside of this is a potential perf impact if the parsing code
doesn't get inlined since the common parsing code has to shuffle around
data that the caller is not intersted in. I don't think this will be a
problem but if it will I suppose it will be solvable (e.g. by using
`#[inline(always)]`).

The enum also looks somewhat nice and perhaps downstream consumers could
make use of it. This change does not expose it yet but is written such
that after exposing it the API would be (mostly) idiomatic.

Closes #4097

jrakibi cb270eae8e Make transaction::Version field private
This commit addresses #4041 by making the transaction::Version field private

Changes:
- Make the `Version` field private with `pub(crate)`
- Rename `non_standard` to `maybe_non_standard` for clarity since it accepts both standard and non-standard versions
- Add `#[inline]` attributes to small, frequently used methods:
  - `as_u32`
  - `maybe_non_standard`

Users now must use either:
- Constants (`Version::ONE/TWO/THREE`) for standard versions
- `maybe_non_standard` method for any version (standard or non-standard)

Pull request description:

  We would like to return an error when doing math ops on amount types. We cannot however use the stdlib `Result` or `Option` because we want to implement ops on the result type.

  Add an `NumOpResult` type. Return this type from all math operations on `Amount` and `SignedAmount`.

  Implement `core::iter::Sum` for the new type to allow summing iterators of amounts.
