Currently there are a couple of errors in the `taproot` module that are
too general, resulting in functions that return a general error type
when a specific one would do.
Split two errors out and use them for for enum variants and function
returns as possible.

The package metatadata never changes and is not necessary to look at
basically ever, put it down the bottom of the manifest out of the way.
Helps to keep features and dependencies closer together.
Refactor only, no logic changes.
We manually implement these methods (and the GeneralHash trait) on newtypes
around sha256t::Hash, because tagged hashes require a bit more work. In
the next commit (API diff) you will see that this affects two hashes,
which are the only things that appear green in the diff.
Users who want to implement their own engine/from_engine types now need
to do it on their own. We do this for the non-Taproot sighash types in
`bitcoin` (though only privately) to demonstrate that it's possible.
This is a continuation of the previous commit, but separated to make
review a little easier. This one replaces test vectors that were
previously computed by hashing garbage into Txids and various other hash
types with new test vectors which are directly-computed garbage
converted to hashes with from_byte_array.
In one case (src/hash_types.rs) this results in changing a bunch of
fixed test vectors. This is okay; this test is supposed to check the
direction of string serialization, which is unaffected by this commit
(or any commit in this PR). The existing test vectors, because they hash
the empty string, result in different bytes depending on the underlying
hash algo (sha256, sha256d, sha256t, etc). The new ones just use the
same fixed test vector for all of them.
This commit also updates a doctest in crypto/sighash.rs which
demonstrates how to manually feed sighash data into a hash engine and
correctly handle the sighash single bug. Because you can no longer
directly get a sighash object from an engine, this particular example
should maybe be rewritten to just encode to a Vec rather than a hash
engine, explaining that maybe you'd do this when implementing a HWW, to
verify the exact data being hashed. Or something.
Unrelatedly, you can check that there are no API changes in this commit
or the last several. The next commit will remove GeneralHash impls and
that's when you'll see changes.
In the next commits we are going to stop exposing the ability to hash
arbitrary data into wrapped hash types like Txid etc. In preparation for
this, stop using these methods internally.
This makes our internal code a little bit uglier and less DRY. An
alternative approach would be to implement the from_engine and engine
methods, but privately (and maybe having a macro to provide this). But I
think this approach is more straightforward.
The one exception is for the Taproot hashes, which are tagged hashes and
currently do not have their own engine type. I will address these in a
later PR because this one is already too big.

We have various different column widths being used in a single rustdoc
block, since we favour 100 for comments around here use it.
No text changes, whitespace only.
We should pass `Copy` types by value not by reference.
Currently this is not done in secp, but lets do it here in bitcoin.
Pass by value:
- `SerializedSignature`
- bitcoin sigs
- secp sigs
- secp `Message`

Pull request description:
The `push_bytes` module has a `private` module that exists solely to protect the invariant on the `PushBytes` inner byte slice. There is a `PushBytes` impl block outside the private module for functions that can not and do not violate the length invariant.
Recently we move the `read_scriptint` method to be on the `PushBytes` but we put it inside the `private` module, since the method only reads off of the slice it cannot invalidate the invariant and does not need to be inside the `private` module.
Move the `read_scriptint` method outside of the `private` module to keep that module as small as possible, helping with its stated aim of being the only place that requires auditing.

Manually implement it for Wtxid, Txid and BlockHash, where the all-zero
"hash" has a consensus meaning. But in general we should not be
implementing this method unless we have a good reason to do so. It can
be emulated or implemeted in terms of from_byte_array.
The use of Wtxid::all_zeros is obscure and specific enough that I am
tempted to drop it. But for txid and blockhash, the 0 hash appears in
actual blockdata and we should keep it.
All other uses of all_zeros were either in test code or in places where
the specific hash was not important and [u8; 32] was a more appropriate
type.
We use 100 column width for rustdoc in this project, while not a super
hard rule the docs on `read_scriptint` are long, using the 100 column
width reduces the line count a reasonable amount.

Note that the few instances remain as they seem required e.g.,

Refactor only, no logic changes.
Drop recursion, reduce memory usage to be logarithmic in size of tree
rather than linear, and put it all in one function rather than three.
Also make the method an trait method on MerkleNode which makes it a
easier on type inference, by writing e.g. TxMerkleNode::calculate_root.
Currently we are defining the two merkle tree hash types in the `block`
module, a better home for them is the `merkle_tree` module.
This is an API breaking change because the types were public in the
`block` module, however the change should/could be unnoticeable to users
if they use the crate level re-export - which is maintained.

There are two limits that the Bitcoin network enforces in regard to
hashing scripts
- For P2SH the redeem script must be less than 520 bytes
- For P2WSH the witness script must be less than 10,000 bytes
Currently we are only enforcing the p2sh limit when creating an address
with `Address::p2sh`.
There are various ways to create addresses from script hashes and if
users manually hash a script then use the `ScriptHash` (or
`WScritpHash`) our APIs assume the script that was hashed is valid. This
means there is the potential for users to get burned by creating
addresses that cannot be spent, something we would like to avoid.
- Add fallible constructors to `ScriptHash` and `WScriptHash`
- Add `TryFrom` impls as well to both types
- Remove the `From` impls
The script in a p2wsh is typically referred to as the witness script not
the redeem script - rename the local test variable to follow suit.
Refactor only, no logic changes.
This test does an odd combination of function calls, its not obvious
what it is supposed to be testing. The `to_p2wsh.is_p2wsh` is already
tested above. The leading `to_p2sh` does not prove anything, one can put
currently pass any script to `to_p2wsh` so this tests nothing.
In preparation for patching the script hashing functionality first
remove this odd test.

Added the missing comment to the `regression_2606()` test. I was not sure where the hex value came from that was used to test that the deserialization fails. The comment was generated by copilot and may need to be edited, it does fit with the error given by deserialize: `OversizedVectorAllocation { requested: 12811880876963004416, max: 4000000 }`.

Remove the shebang line from `crates.sh` and the various `test_vars.sh`
scripts. Add a `shellcheck` directive to inhibit the no-shebang warning.
Fix: #2764
We just added to now types that are thin wrappers around `u32`s for
block heights and intervals.
Add `Encodable` and `Decodable` impls and use the new types. While we
are at it re-export the types from the crate root so users don't have to
dig into the `units` crate.
9e4b092fce psbt: Use macro instead of function (Tobin C. Harding)
Pull request description:
We have a private function that makes use of the `Hash` trait to generically hash map entries. This usage makes patching the `hashes` module difficult. We can achieve the same thing by using a macro and passing in the concrete type.
This is an internal change, no effect on logic or public API.

We would like to move the dependency on `hex_lit` to be a

`--cfg=bench` and during such a build our dev-dependencies are not
available.
We also have the `test_hex_unwrap` macro in the `hex` crate and since
the bench code is more or less test code (and the macro call is not
being benchmarked) we can use that macro instead.

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.

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.

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.

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.
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.
As part of the ongoing effort to improve `hashes`; stop using slicing of
hash types and use `as_byte_array()` to get an array reference instead.
This gives us more flexability to modify the `hashes` module.
If one writes signing data using one of the two
`*_encode_signing_data_to` functions then creating the message to sign
is slightly nuanced and different for each of the functions. For Taproot
one must use a specific tagged hash and for ECDSA one must use a sha256d
hash.
Add documentation that explains the hashing requirements for each
function.
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.

There is some confusion as to what exactly the bip specifies however Bitcoin Core RPC call `getaddressinfo` returns a derivation path with a leading "m/". This means we need to be able to parse it irrespective of what the bip says.
Be more liberal in what we accept as a derivation path, including both with and without the leading 'm/'.
Leave the full investigation of the bip to a later date.

The deprecation notice for `is_provably_unspendable` contains "is not

well be useful to them. Use the more helpful text that already exists in
rustdoc on the function.

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.
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.
There is no need to panic if input index is out of bounds because we
have a function to check the validity of the `input_index` argument and
use it in other places already.

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.
Currently we are using `Self` (in backticks) in the docs to functions
defined by the `do_iml` macro, this is a bit lazy, we can do better than
that.
Use `doc` attribute and the `$ty` macro variable to construct the docs
to use the type name.
Use a code comment to document the calling restrictions of private
function `from_hex_internal`. (Code comment because comment is not well
formed as per convention in this codebase.)
Improve the rustdocs on the private `U256` type by doing:
- Remove link to self within constructors, just use backticks
- Use `U256` instead of `Self` or `self`
- Fix incorrect usage of `CompactTarget` [0]
[0] We knew this was wrong when we merged it but because the docs are
private we elected to do this follow up patch.
Currently `Magic` has per network consts but no way to dynamically get
the magic bytes for a network. Note also that we are currently trying to
reduce the usage of `Network` in the public API.
Add a public constructor to the `Magic` type that accepts a `Params`
parameter to determine the network to use.
The `pow` types implement `fmt::LowerHex` but do not implement hex
parsing.
Add inherent methods `from_hex` and `from_prefixed_hex` to the
`pow` types.

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.
These two functions calculate the min/max threshold transition which is
a _target_ not a "difficulty" number. Using "difficulty" in the function
name is unnecessarily confusing.
Rename and deprecate the functions.
The maximum "attainable" target is a `rust-bitcoin` thing, Core use max
unattainable.
Deprecated the `Params::pow_limit` field and add a new field
`max_attainable_target`.
The `Params` type is `non_exhaustive` so this is not an API breaking
change.
What we really want is the maximum target, but since this is a const in
`Params` use an `AsRef<Params>` argument in the `difficulty` functions.
Requires implementation of `AsRef<Params> for Params`.
The `difficulty` calculation requires dividing a target value by `self`.
Add an assertion that `self` is not zero to help devs debug this.
Note that this should never really be hit, but its possible there is a
bug somewhere causing the target to be set to zero - so this may help
debugging.
Also, add panics section to rustdocs.
This lint triggers when parsing a reference to a large struct as a
generic argument, which is wrong.
Allow it crate wide because [subjectively] this lint never warns for
anything useful.
