Merge rust-bitcoin/rust-bitcoin#2076: Re-write the weight/size API
c34e3cc7cc Re-write size/weight API (Tobin C. Harding)
73f7fbf520 Add code comments to transaction serialization (Tobin C. Harding)
29f20c1d0b Add segwit serialization constants (Tobin C. Harding)

Pull request description:

  Audit and re-write the weight/size API for `Block` and `Transaction`. First two patches are trivial, patch 3 contains justification and explanation for this work, copied here:

  ```
      Recently we introduced a bug in the weight/size code, while
      investigating I found that our `Transaction`/`Block` weight/size APIs
      were in a total mess because:

      - The docs were stale
      - The concept of weight (weight units) and size (bytes) were mixed up

      I audited all the API functions, read some bips (141, 144) and re-wrote
      the API with the following goals:

      - Use terminology from the bips
      - Use abstractions that mirror the bips where possible
  ```

  Please note, this PR introduces panics if a sciptPubkey overflows the calculation `weight = spk.size() * 4`.

  Fix #2049

Merge rust-bitcoin/rust-bitcoin#2084: Add `Witness::p2wpkh` constructor
5901d35095 Add push_p2wpkh function on Witness (Tobin C. Harding)
8cd409d561 Deprecate push_bitcoin_signature (Tobin C. Harding)

Pull request description:

  In order to create the witness to spend p2wpkh output one must create a `Witness` that includes the signature and the pubkey, we should have a function for this.

  ## Notes
  The PR originally added a `push_p2wphk` method, this is now instead a constrcutor `Witness:p2wpkh` (after review discussion below).

  - Patch 1 changes `push_bitcoin_signature` to take an `ecdsa::Sigtnture` instead of an `ecdsa::SerializedSignature`
  - Patch 2 takes a `secp256k1::PublicKey` removing the need for an error path (discussed below).

Deprecate push_bitcoin_signature
The `Witness::push_bitcoin_signature` method is old and a bit stale.
Bitcoin has taproot signatures now so the name is stale, also we have
the `crate::ecdsa::Signature` type that holds the secp sig and the hash
type so we can use that instead of having two separate parameters.

Add a new, up to date, `Witness::push_ecdsa_signature` function and
deprecate the `push_bitcoin_signature` one.

Remove default impl from transaction version
There is no logical default for the transaction version number, there is
only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version
they want not rely on us making the choice.

(I originally added this impl to support testing, this was in hindsight
the wrong thing to do, props to Sanket for noticing.)

Merge rust-bitcoin/rust-bitcoin#2073: Feature: Count sigops for Transaction
158ba26a8a Feature: Count sigops for Transaction (junderw)

Pull request description:

  I copied over the sigop counting logic from Bitcoin Core, but I made a few adjustments.

  1. I removed 2 consensus flags that checked for P2SH and SegWit activation. This code assumes both are activated. If we were to include that, what would be a good way to go about it? (ie. If I run this method on a transaction from the 1000th block and it just so happened to have a P2SH-like input, Bitcoin Core wouldn't accidentally count those sigops because the consensus flag will stop them from running the P2SH logic. Same goes for SegWit)
  3. Since there's no guarantee that we have an index from which we can get the prevout scripts, I made it into a generic closure that looks up the prevout script for us. If the caller doesn't provide it, We can only count sigops directly in the scriptSig and scriptPubkey (no P2SH or SegWit).

  ## TODO
  - [x] Write tests for transaction sigop counting

  ~~Edit: The test changes are just to get the 1.48 tests passing. I'll remove them and replace them with whatever solution that is agreed upon in another PR etc.~~

  Edit 2: This is the code I used as a guide:

  8105bce5b3/src/consensus/tx_verify.cpp (L147-L166)

  Edit 3: I found a subtle bug in the implementation of `count_sigops` (https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687)

95b7a95fc2 test: correct psbt used for regression test (Subhradeep Chakraborty)

Pull request description:

  The `unknown` key used in the `Psbt` (in `serde_regression_psbt` test) is not really unknown. Also the `preimages` in the `Input` don't seem to be valid. Though they don't affect the tests because of the `serde::serialize`, the `Psbt` itself is invalid and hence this PR.

Add transaction::Version data type
BIP-68 activated a fair while ago (circa 2019) and since then only
transaction versions 1 and 2 have been considered standard.

Currently in our `Transaction` struct we use an `i32`, this means users
can construct a non-standard transaction if they do not first look up
what the value should be. We can help folk out here by abstracting over
the version number.

Since the version number only governs standardness elect to make the
inner `i32` public (ie., not an invariant). The aim of the type is to
make life easy not restrict what versions are used.

Add transaction::Version data type that simply provides two consts `ONE`
and `TWO`.

Add a `Default` impl on `Version` that returns `Version::TWO`.

In tests that used version 0, instead use `Version::default` because the
test obviously does not care.

Merge rust-bitcoin/rust-bitcoin#2078: Script helper to classify bare multisig
acbf23aaa5 Add `is_multisig` helper to Script type (Clark Moody)

Pull request description:

  A new `is_multisig` helper method to classify bare multisig output scripts.

  The form of a valid multisig script is:
  - Pushnum `M`
  - &lt;N&gt; pubkeys
  - Pushnum `N`
  - `OP_CHECKMULTISIG`

  `N` must equal the number of pushed pubkeys, and `M` must be less than or equal to `N`.

  I've tested this against the RPC output of Core at the block level, checking that the total number of multisig outputs matches.

  ```
  Block 350338, 89 multisig
  Block 350340, 29 multisig
  Block 350341, 4 multisig
  Block 350343, 579 multisig

Pull request description:

  When implementing some tests for the Transaction PR, I noticed that there were coinbase transactions that would pass Bitcoin Core parsing and fail my code.

  It turns out that the Script parsing for sigops calls `break`  to exit the loop and returns the current n value whenever there is an EarlyEndOfScript error.

Pull request description:

  One encodes to a writer and decodes from a reader, most of the time in the consensus `Encodable`/`Decodable` traits we use generic `R`/`W` and variable `r`/`w` but there are other places that use other characters.

  While touching these lines note also that there are a bunch of unneeded `mut`s, I'm not sure why since usually between the compiler and the linter `mut` is handled correctly.

  Make implementations of `Encodable` and `Decodable` uniform by:
  - Use R/W and r/w for trait and variable name
  - Remove unneeded mut

Add VarInt from implementations by way of macro
Throughout the codebase we cast values to `u64` when constructing a

impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single

Remove usage of ThirtyTwoByteHash
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.

Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.

This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.

  The word "segwit" refers to segwit v0 and taproot but these functions are version specific. Add `v0` into the function names.

  This is similar to #1994, both based on recent post of mine to bitcoin dev mailing list.

Export all hash types
During the 0.30.0 release we removed the re-exports of hash types. This
upset some folk and since the aim of our re-exports is not exactly clean
as well as the fact that the public API surface is not yet fixed just
re-export all the hash types at the crate root again.

This is 1792 but does not use a wildcard and also grabs the other
hashes that we recently moved.

- Rename `segwit_encode_signing_data_to` to

- Add `p2wpkh_signature_hash` and `p2wsh_signature_hash` functions

We keep the single encode function because the error handling is better
that way.

sighash types of wrapped p2wsh.

Pull request description:

  - Patch 1 is docs cleanup
  - Patch 2 adds two functions to `FeeRate`

  From the commit log of patch 2:

      Calculating the absolute fee from a fee rate can currently be achieved
      by creating a `Weight` object and using
      `FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
      can add two public convenience functions that make discovery of the
      functionality easier.

      Add two functions for calculating the absolute fee by multiplying by
      weight units (`Weight`) and virtual bytes (by first converting to weight
      units).

  This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

Pull request description:

  EDIT: The commit hashes below are stale but the text is valid still.

  In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.

  The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.

  Its all pretty trivial except:

  - commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
  - comimt `5a196535 Add InvalidSighashTypeError`
  - commit `05772ade Use defensive documentation`

  Particularly the last one might be incorrect/controversial.

  Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.

  Thanks

Use standard set of derives on all error types
As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.

    `#[derive(Debug, Clone, PartialEq, Eq)]`

Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.

If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

Add non_exhaustive to SignError
Errors that may have variants added/removed should have `non_exhaustive`
on them.

Pull request description:

  Use the newly released `hex-conservative` crate, by doing the following:

  - Depend on `hex-conservative` in `bitcoin` and `hashes`
  - Re-export `hex-conservative` as `hex` from both crate roots.
  - Remove all the old hex code from `hashes`
  - Remove all the old hex code from `internals`
  - Remove the now unused `internals::prelude`
  - Fix all the import statements (makes up the bulk of the lines changes in this patch)

Merge rust-bitcoin/rust-bitcoin#1954: Avoid vector allocation in `RawNetworkMessage` encoding

bc66ed82b2 Impl Encodable for NetworkMessage (Riccardo Casatta)
8560baaca2 Make fields of RawNetworkMessage non public (Riccardo Casatta)

Pull request description:

  This PR removes the need to serialize the inner NetworkMessage in the RawNetworkMessage encoding, thus saving memory and reducing allocations.

  To achieve this payload_len and checksum are kept in the RawNetworkMessage and checksum kept in CheckedData, to preserve invariants fields of the struct are made non-public.

Move EncodeSigningDataResult to sighash module
This type was defined in the `transaction` module because it was
originally used in a function that had been deprecated in favour of
moving the logic to the `sighash` module.

We just removed the deprecated code so we can now move this type to the
`sighash` module where it is used.

Avoid serialize inner data in RawNetworkMessage
RawNetworkMessage keep the payload_len and its checksum in the struct, thus
is not needed to serialize the inner network message

pub in fields of both RawNetworkMessage and CheckedData are removed so that
invariant are preserved.
