Use concrete type for all_zeros call
Currently we use the `Hash` trait in a bunch of places to call
`all_zeros`. We are attempting to improve the `hashes` API and this
usage is both unnecessary and also hindering that effort.

Use the concrete type (e.g. `BlockHash`) instead of calling through the
trait method.

Refactor only, no logic changes.

Merge rust-bitcoin/rust-bitcoin#2740: Add difficulty adjustment calculation
47dc4a3180 feat(pow): add difficulty adjustment calculation (Rob N)

Pull request description:

  Hi, I hit a roadblock with the current `pow` API. As far as I can tell, the only workaround to calculate the next work required similar to `bitcoin/src/pow.cpp` is to use a general big integer library, convert the `Target` to bytes, do the math, and convert back to `Target` from bytes. I have also been working with [Floresta](780ea8d0b0) and their [solution](780ea8d0b0/crates/floresta-chain/src/pruned_utreexo/consensus.rs (L187)) was to fork off and exposed the `U256` struct publicly on their branch. I think these home brewed difficulty adjustment solutions will continually pop up, so I created a `from_next_work_required` method to return a `Target`. My work veers significantly from #2180, as I only provided a single method to do so, without further guidance on when exactly this retarget occurs.

  I am happy to add tests once I get further direction from maintainers if this as a likelihood of being accepted or not. Thanks.

Deprecate to_vec in favour of to_bytes
Currently we have to method names for the same thing "copy this object
into a vector". The library is easier to use if we are uniform and just
use one.

Elect to use `to_bytes`, for context see discussion in PR #2585.

Improve array macros
Currently we have two macros used when creating array wrapper types,
one is in `internals` and the other in `bitcoin::internal_macros`. It
is not immediately obvious what is what and why there are two.

Improve the macros by:

- Move the inherent functions to `impl_array_newtype`
- Use `*_byte_array` for the names instead of `*_bytes` for functions
  that return arrays
- Add `as_bytes` to return a slice
- Add `to_bytes` to return a vector
- Re-name the other macro to match what it now does

Pull request description:

  First three patches are preparation, improvements to the units tests in `sha256t`.

  From the final patch:

      Displaying backward is an anomaly of Bitcoin Core's early days and the
      double SHA256 hash type. We should not let this unfortunate beast leak
      out into other places.

      Default to displaying forward when creating a new tagged hash and remove
      all the explicit attributes from `bitcoin` that just clutter the code.

  This is an API break and may quietly break some users downstream - eventually we should stop doing that sort of thing.

hashes: Modify trait bounds
Currently we require indexing trait bounds as well as `Borrow` on the
`Hash` trait. We also already implement `AsRef`.

It was observed that `Borrow<[u8]>` does not best describe what we want
from the `Hash` trait implementor but rather `AsRef<[u8]>` does.

Remove all the inexing trait bounds. Remove the `borrow::Borrow<[u8]>`
trait bound. Add a `convert::AsRef<[u8]>` trait bound.

This leaves the `Borrow<[u8]>` implementation for hashes created with
`hash_newtype`, I'm not sure if this should be removed or not.

26b9782d8b CI: Re-write run_task.sh (Tobin C. Harding)

Pull request description:

  Recently we re-wrote CI to increase VM level parallelism, in hindsite this has proved to be not that great because:

  - It resulted in approx 180 jobs
  - We are on free tier so only get 20 jobs (VMs) at a time so its slow to run
  - The UI is annoying to dig through the long job list to find failures

  Have another go at organising the jobs with the main aim of shortening total run time and making it easier to quickly see fails.

  Re-write the `run_task.sh` script, notable moving manifest handling to the workflow. Also don't bother testing with beta toolchain.

  ### Note on review

  The diff is hard to read for `rust.yml`, I tried splitting out a bunch of separate patches but it resulted in the same thing (because there are so many identical lines in the yaml file). I suggest just looking at the yaml file and not the diff.

WASM Note

Removes the `cdylib` and `rlib` from the manifest patching during wasm
build - I do not know the following:

- Why this breaks on this PR but not on other PRs
- Why I can't get wasm test to run locally on master but PRs are passing
- What the `cdylib` and `rlib` were meant to be doing

This is the docs from: https://doc.rust-lang.org/reference/linkage.html

* --crate-type=cdylib, #![crate_type = "cdylib"] - A dynamic system
library will be produced. This is used when compiling a dynamic library
to be loaded from another language. This output type will create *.so
files on Linux, *.dylib files on macOS, and *.dll files on Windows.

* --crate-type=rlib, #![crate_type = "rlib"] - A "Rust library" file
will be produced. This is used as an intermediate artifact and can be
thought of as a "static Rust library". These rlib files, unlike
staticlib files, are interpreted by the compiler in future linkage. This
essentially means that rustc will look for metadata in rlib files like
it looks for metadata in dynamic libraries. This form of output is used
to produce statically linked executables as well as staticlib outputs.

bitcoin: Bump version to 0.32.0-rc1
In preparation for dropping the first release candidate bump the version
and add a changelog.

Please not I went to much more effort that usual with the changelog,
open to review on the overall form - not promising I'll change it but
definitely would like to keep iterating and improving.

If this changelog is appreciated then FWIW I don't think we should
bother automating it, a machine does not have all the context required
to create it.

Enable internals "alloc" feature
We have 2 crates that require an allocator, `bitcoin` and `base58ck` -
these crates should enable the "alloc" feature when depending on
`internals`.

For `units` we use the `internals::error::InputString` but do not enable
the "alloc" feature - this is a bug, it means that the parsed string is
being lost from the error types that use `InputString`.

Enable "alloc" for `bitcoin`, `base58ck`, and `units`.

- `bitcoin` and `base56ck` is just for good measure so we don't get
  bitten later on.
- `units` is a bug fix and requires a point release.

psbt: Return the internal key for key path spend
When signing a Taproot input (in a PSBT) using a key path spend we
currently return the pubkey associated with key that signs. However it
is common to think of the internal key as being the one that signs even
though this is not technically true. We also have the internal key in
the PSBT so matching against it is less surprising.

When using the `Psbt` type to sign a Taproot input using a key path
spend return the internal key.

Minimize usage of Network in public API
A release or so ago we added `non_exhaustive` to the `Network` enum,
this turned out to make usage of the enum un-ergonomic for downstream
users. After much debate we decided that a way forward was to just
minimize the usage of the enum in the public API by instead use
`AsRef<Params>` so that downstream could define their own network enum
based on the networks they support.

Minimize usage of `Network` by using `AsRef<Params>` as a parameter type
instead. "minimize" because the `Network` still appears in some places.

Improve API for max target threshold calculation
The maximum target threshold has a network dependant upper bound.
Currently we are not checking this bound. One complication is that there
is currently heated open debate around the `Network` type.

We can bypass the `Network` issue by using `AsRef<Params>` instead.

Add a function that does the checks based on the `Params` type as well
as an unchecked version.

When we renamed `dust_value` to `minimal_non_dust` we forgot to keep the
original and deprecated it, doing so assists with the upgrade path.

Pub back in deprecated `dust_value`, linking to the rename.

Refactor witness_version and is_witness_program
These two functions are related. We cannot, by definition, get the
witness version from a script that is not a witness program but
currently the code is not linking these two things.

Refactor by doing:

- Move the check of the witness program bip rules to `witness_version`
- Call `witness_version().is_some()` in the predicate

Improve the docs while we are at it to include the bip text in the
rustdoc. Note I didn't bother referencing the segwit bip number, this
bip text is pretty well known.

hashes: Bump version to v0.14.0
In preparation for release add a changlelog entry and bump the version.

I'm not 100% sure that this release is API breaking, dependencies
definitely changed. The rest might be only additives but I didn't bother
looking exactly because I think its better to bump the minor version and
err on the side of caution.

Note the hashes 0.13.0 dependency stays in the dependency graph because
of secp, we can update secp after releasing `hashes` then update the
secp dependency in `rust-bitcoin` thereby removing the `hashes v0.13.0`
dependency - phew.

bitcoin: Stop using base58 errors
We are currently using the `base58::Error` type to create errors in
`bitcoin`, these are bitcoin errors not `base58` errors.

Note that we add what looks like duplicate
`InvalidBase58PayloadLengthError` types but they are different because
of the expected length. This could have been a field but I elected not
to do so for two reasons:

1. We will need to do so anyways if we crate smash more
2. The `crypto::key` one can have one of two values 33 or 34.

With this applied we can remove the now unused error variants from
`base58::Error`.

  This PR fixes a bug introduced by me in #2473, and uncovered by #2563 - amazing that it was found so quickly!

  Constructing a pubkey using `PublicKey::from_slice` can fail for reasons other than just incorrect length - we should not be using `expect` but rather returning the error.

Merge rust-bitcoin/rust-bitcoin#2565: Removes txid prefix in transaction IDs
56132f59d5     Remove the `:#` formatting for `hex_fmt_impl` macro (448 OG)

Pull request description:

  This commit attempts to solve #2505  by ensuring that formatting is not forced using the `:#` in the hex macro code generating in macro rule `hex_fmt_impl` in the hashes/utils.rs file.

  The write! macro forces all formatting to add the prefix `0x` by adding an alternate by (#) default

  ```rust
  impl<$($gen: $gent),*> $crate::_export::_core::fmt::Debug for $ty<$($gen),*> {
              #[inline]
              fn fmt(&self, f: &mut $crate::_export::_core::fmt::Formatter) -> $crate::_export::_core::fmt::Result {
                  write!(f, "{:#}", self) // <-- This is where the formatting is being forced.
              }
          }
  ```

  By removing this formatting, the `:#` must be specified by the user in order for a prefix to be added.

  ```rust
  let outpoint = bitcoin::OutPoint::default();
      println!("{:?}", &outpoint);
      println!("{:#?}", &outpoint);
      println!("{:#}", &outpoint);
      println!("{:x}", &outpoint.txid);
      // `{:#}` must be specified to pretty print with a prefix
      println!("{:#}", &outpoint.txid);
      dbg!(&outpoint);
      dbg!(&outpoint.txid);
  ```

  The PR also adds testcase for this when running `cargo test` .

Split relative locktime error up
The `relative` module has a single general error type, we are moving
away from this style to specific error types.

Split the `relative::Error` up into three error structs.

Note the change of parameter `h` to `height`, and using `h` as the
pattern matched variable - this makes sense because it gives the
variable with large scope the longer name.

hash_types: add unit tests for display of all hash types in the library
This can be checked against the 0.29.x branch, and against the commit
prior to #1659 (40c246743b^) and you will see that it is consistent
EXCEPT:

* In rust-bitcoin 0.29.x we did not have multiple sighash types, only
  `Sighash`; we now have `LegacySighash`, `SegwitV0Sighash`, and
  `TapSighash`.
* In #1565 we deliberately changed the display direction of the
  sighashes, to match BIP 143.

Fixes #2495.

Re-export P2shError
The `address` module is currently publicly re-exporting all error types
that appear as return values for any pubic function, except for the
`P2shError` - we should be uniform.

This re-export of error thing has not been discussed/agreed upon as a
policy but I have been doing it for the last few months anytime I
introduced an `error` module - there has been no push back so I assumed
it was acceptable. Before 1.0 we should probably have a policy on this.

Do infallible int from hex conversions
We have three integer wrapping types that can be created from hex
strings where the conversion from an integer is infallible:

- `absolute::LockTime`
- `Sequence`
- `CompactTarget`

We would like to improve our handling of the two prefix characters (eg
0x) by making it explicit.

- Modify the inherent `from_hex` method on each type to error if the
input string does not contain a prefix.

- Add an additional inherent method on each type `from_unprefixed_hex`
that errors if the input string does contain a prefix.

This patch does not touch the wrapper types that cannot be infallibly
constructed from an integer (i.e. absolute `Height` and `Time`).

Pull request description:

  For now I have tried to group those functions which can produce more than one error and changed the functions which were  generating single error from `Key::Error` to the respective error. Let me know if this needs to be changed.

  Also in `psbt/error.rs` I have changed the `InvalidPublicKey(crate::crypto:🔑:Error)` to `InvalidPublicKey(crate::crypto:🔑:FromSliceError)`. What should be done here?

  Changes -
  - in `from_slice` changed the `error` to `FromSliceError`.
  - in `verify` changed to `secp256k1::Error` as it can return only one error.
  - in `from_str` changed to `FromSliceError`.
  - in `CompressedPublicKey` changed `verify` from `Error` to `secp236k1::Error` as it only returns one error.
  - introduces CompressedPublicKeyError
  - Removes impl from `bip32.rs`

Remove unnecessary m/ prefix requirement
In BIP0032, m is used as a variable for the root extended key. It is not
meant to be used as a constant prefix when serializing paths.

Update the DerivationPath parser to no longer require the m prefix.
Remove the m prefix from the unit tests and the bip32, ecdsa-psbt,
and taproot-psbt examples.

Add two public API functions on the two public keys, both called
`p2wpkh_script_code` to do exactly as the name suggests.

Of note, I was not able to find anywhere to use these in example code,
this is because of we always use the new `p2wpkh_signature_hash`
function. The new functions may be useful for a user calling
`segwit_v0_encode_signing_data_to`. The may help document the library as

Martin Habovstiak 93dba898c2 Improve lock time errors
The errors returned from various lock time functions had several issues.
Among the obvious - `Error` being returned from all operations even when
some of its variants were unreachable, there were subtle issues around
error messages:

* `ParseIntError` didn't contain information whether the parsed object
   is `Height` or `Time`.
* Logically overflow and out-of-bounds should be the same thing but
  produced different error messages.
* Mentioning integers is too technical for a user, talking about upper
  and lower bound is easier to understand.
* When minus sign is present `std` reports it as invalid digit which is
  less helpful than saying negative numbers are not allowed.

It is also possible that `ParseIntError` will need to be removed from
public API during crate smashing or stabilization, so avoiding it may be
better.

This commit significantly refactors the errors. It adds separate types
for parsing `Height` and `Time`. Notice that we don't compose them from
`ParseIntError` and `ConversionError` - that's not helpful because they
carry information that wouldn't be used when displaying which is
wasteful. Keeping errors small can be important.

It's also worth noting that exposing the inner representation could
cause confusion since the same thing: out of bounds can be represented
as an overflow or as a conversion error. So for now we conservatively
hide the details and even pretend there's no `source` in case of
overflow. This can be expanded in the future if needed.

The returned errors are now minimal. `LockTime` parsing errors are
currentlly unchanged.

  * The `Io` error wariants were duplicated

Martin Habovstiak a4d01d0b6c Factor out `io::Error` from sighash errors
The hadnling of `io::Error` in sighash had a few problems:

* It used `io::ErrorKind` instead of `io::Error` losing inforation
* Changing `io::ErrorKind` to `io::Error` would disable `PartialEq`&co
* The `Io` error wariants were duplicated

It turns out all of these can be solved by moving the `Io` variant into
a separate error.

Require BufRead instead of Read
Our decoding code reads bytes in very small chunks. Which is not
efficient when dealing with the OS where the cost of a context switch is
significant. People could already buffer the data but it's easy to
forget it by accident.

This change requires the new `io::BufRead` trait instead of `io::Read`
in all bounds.

Code such as `Transaction::consensus_decode(&mut File::open(foo))` will
break after this is applied, uncovering the inefficiency.

This was originally Kix's work, done before we had the `io` crate.
Changes to `bitcoin` were originally his, any new mistakes are my own.
Changes to `io` are mine.

Merge rust-bitcoin/rust-bitcoin#2248: Implement ArbitaryOrd for absolute::LockTime
518f0970c9 Implement ArbitaryOrd for absolute::LockTime (Tobin C. Harding)

Pull request description:

  At times we would like to provide types that do not implement `PartialOrd` and `Ord` because it does not make sense. I.e we do not want users writing `a < b`. This could range from kind-of-iffy to down-right-buggy (like comparing absolute locktimes).

  However this decision effects downstream users who may not care about what the ordering means they just need to use it for some other reason e.g., to use as part of a key for a `BTreeMap` (as we do in `miniscript` requiring the `AbsLockTime` type).

  A solution to this problem is to provide a wrapper data type that adds `PartialOrd` and `Ord` implementations. I wrote the `ordered` crate is for this very purpose.

Improve Signature field names
Applies to both `ecdsa::Signature` and `taproot::Signature`.

Re-name the `Signature` fields with more descriptive names. The
names used were decided upon in the issue discussion.

Impove rustdocs while we are at it.

Note, the change to `sign-tx-segwit-v0` is refactor only, the diff does
not show it but we have a local variable already called `sighash_type`
that is equal to `EcdsaSighashType::All`.

Includes a function argument rename as well, just to be uniform.

Fix: #2139

Implement ArbitaryOrd for absolute::LockTime
At times we would like to provide types that do not implement
`PartialOrd` and `Ord` because it does not make sense. I.e., we do not
want users writing `a < b`. This could range from kind-of-iffy to
down-right-buggy (like comparing absolute locktimes).

However this decision effects downstream users who may not care about
what the ordering means they just need to use it for some other reason
e.g., to use as part of a key for a `BTreeMap` (as we do in `miniscript`
requiring the `AbsLockTime` type).

A solution to this problem is to provide a wrapper data type that adds
`PartialOrd` and `Ord` implementations. I wrote the `ordered` crate is
for this very purpose.

Feature gate a new dependency on `ordered` and implement `ArbitraryOrd`
for `absolute::LockTime`.

Merge rust-bitcoin/rust-bitcoin#2255: Fix: TxOut::minimal_non_dust and Script::dust_value
1b23220d10 Fix: TxOut::minimal_non_dust and Script::dust_value (Jonathan Underwood)

Pull request description:

  Fixes #2192

  TxOut::minimal_non_dust has 3 problems.

  1. There is an invisible dependency on Bitcoin Core's default minrelaytxfee value. It has been made explicit.
  2. There is an off by one error. The dust limit comparison uses < and therefore `+ 1` was not needed. It has been fixed.
  3. It was not returning 0 amount for OP_RETURN outputs.

  Script::dust_value has 2 problems.

  1. The dust amount depends on minrelaytxfee which is configurable in Bitcoin Core. This method was not configurable.
  2. The division operation was done before multiplying the byte amount, which can cause small differences when using uncommon scripts and minrelaytxfee values.

Pull request description:

Martin Habovstiak e531fa612b Move `TaprootMerkleBranch` and impl `IntoIterator`
Since the iterator created by `IntoIterator` should be called `IntoIter`
we move the whole `TaprootMerkleBranch` to its own module which contains
the type to avoid confusion. This has an additional benefit of reducing
the scope where the invariant could be broken. This already uncovered
that our internal code was abusing access to the private field (although
the code was correct).

To implement the iterator we simply delegate to `vec::IntoIter`,
including overriding the default method which are likely to be
implemented by `Vec` more optimally. We avoid exposing `vec::IntoIter`
directly since we may want to change the representation (e.g. to
`ArrayVec`).

Remove Network from AddressInner
An `AddressInner` struct is created when parsing address strings however
address strings do not map 1:1 to `Network` because signet and testnet
use the same bech32 prefix "tb".

We can fix this by inlining the `Payload` variants into `AddressInner`
and adding prefix enums for legacy addresses and a `KnownHrp` for bech32
addresses.

Also enables removing the `AddressEncoding` struct as we can display the
`AddressInner` struct directly. (The `Display` impl is on `AddressInner`
and not directly on address to ignore the `NetworkValidation` wrapper,
may be able to be simplified still further.)

Calling `wpubkey_hash` on a key that is uncompressed is flat out an

key should never be compressed, however, for historical reasons we do

an error to call `wpubkey_hash` on a an uncompressed pubkey. This adds
documentation and potentially might assist debugging for newer devs.

  Rust version 1.56.0 introduced edition 2021. Shortly afterwards, on October 21 2021 Rust version 1.56.1 was released.

  Debian stable is currently shipping `rustc 1.63.0`. Our stated MSRV policy is: In Debian stable and at least 2 years old. Therefore our MSRV policy is met by Rust version 1.56.1 and we can strat to bump our MSRV org wide. Start by bumping the `rust-bitcoin` and `hashes` MSRV to Rust 1.56.1

  Start by bumping the `rust-bitcoin` and `hashes` MSRV to Rust 1.56.1, includes:

  - Update docs.
  - Update CI and remove pinning.
  - Update the build files and remove now stale cfg attributes rust_v_1_x for values less than the new MSRV.
  - Use new `IntoIterator` for arrays so we no longer need to allocate a vector to iterate.
