Use `bash` instead of `sh` to run shell scripts.
We would like to support Nix users who do not typically have any shell

0997382772 io: Enable alloc from std (Tobin C. Harding)
ba1166a63b Make crate level attributes uniform (Tobin C. Harding)
Pull request description:
Make the trait level attributes uniform across all released crates in the repo. Excludes things that are obviously not needed, eg, bench stuff if there is not bench code.
- Remove `uninhabited_references` - this is allow by default now.
- Remove `unconditional_recursion` and mark the single false positive we have with an `allow`.
Note, this does not add `missing_docs` to the `io` crate. There is an open PR at the moment to add that along with the required docs.

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.
Make the trait level attributes uniform across all released crates in
the repo. Excludes things that are obviously not needed, eg, bench stuff
if there is not bench code.
- Remove `uninhabited_references` - this is allow by default now.
- Remove `unconditional_recursion` and mark the single false positive we
have with an `allow`.
Note, this does not add `missing_docs` to the `io` crate. There is an
open PR at the moment to add that along with the required docs.
The code originally used `if` and incorrectly casted the value into
`usize` rather than `u64`. This change replaces the whole thing with
`unsigned_abs`.

As is customary add a `From` impl for the `ParseIntError` and use `?`.

there is a `From` impl for one of the variants and not the other.

each to get a reference to an input or output respectively.

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.

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.

a8d50a5541 Remove Push enum (Tobin C. Harding)
Pull request description:
The `Push` enum is only ever used to get access to one of its variants. Since it is a private type we can remove it entirely and just return `PushBytes` from the `last_pushdata` function.
Needs careful review but I believe the function name is still correctly descriptive.

The `as_unchecked` method is never dangerous to call because an
`Address<UncheckedNetwork>` provides a subset of functionality that is
always ok to use. It is only dangerous to go the other way unchecked to
checked.
This lint triggers on `fn input_len(&self) -> usize { match *self {} }`
where Self is an infallible type, claiming that the dereference of self
is UB. Maybe it would be, if this were possible. But it's not, and this
is literally the only point of using infallible types, so this lint is
always wrong.
Enabled in rustc 1.76 as warn by default.
This method is not really that useful because it checked an arbitrary
condition. There already exists `OP_RETURN` semantics and the method
didn't cover all possible ways the script may be invalid.
This deprecates the method and documents why.

BIP-32 only differentiates between mainnet and some testnet when
encoding and decoding xpubs and xprivs. As such we can use the new
`NetworkKind` type instead of `Network` throughout the `bip32` module.
We only use the network to serialize and deserialize from WIF.
For this we only really need network kind since WIF only differentiates
between mainnet and non-mainnet.
Add a new type `NetworkKind` the describes the kind of network we are
on, ether mainnet or one of the test nets (testnet, regtest, signet).
Do not use the type yet.

The `bitcoinconsensus` crate is not fully under our control because it
exposes code from Core, so we cannot guarantee its stability across
versions. To make our semver compliance easier we can fully encapsulate
the `bitcoinconsensus` crate so it does not appear in our public API.
However, it is useful to have the crate itself exported, here we add an
"unstable" feature and only publicly export the `bitcoinconsensus` crate
if the "unstable" feature is enabled.
P2WPKH requires keys to be compressed which introduces error handling
even in cases when it's statically known that a key is compressed. To

This also changes relevant code to use `CompressedPublicKey` instead of

There is no advantage in having `io::Read` as opposed to `Read` and
importing the trait. It is surprising that we do so.
Remove `io::` path from `io::Read` and `io::Write`. Some docs keep the
path, leave them as is. Add import `use io::{Read, Write}`.
Refactor only, no logic changes.
When we use the `fmt::Write` trait it is just to call its methods, we
can therefore, without any change to the logic, use `as _` when
importing the trait. This prevents naming conflicts.
Done in preparation for importing the `io::Write` trait.
Generic types can be single letters, and a writer is conventionally, in
this codebase at least, called `W`.
Use `W` instead of `Write` with no loss of clarity.

An `AddressInner` struct (contains `Network` field) 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".

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.

Since we do `& 1`, only 0 and 1 are possible values, so the error return
there can never happen. I made this explicit by manually setting the
parity.
This is a rebase of Steven's change with a rewrite of `match` to not
panic.
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`).
The type is naturally a collection of hashes so make it behave that way
by implementing `Deref`, `AsRef`, `Borrow` and their mutable versions as
well as `IntoIterator` for its reference. `IntoIterator` for itself is
not yet implemented because it's a bit more complicated.
While `clippy` now allows `TBD` to be used in `since` parameter of
`deprecated` attribute it is only available in the newest, nightly,
version. Switch `clippy` version to nightly to enable the `TBD` value.

In the 0.31.0 release we renamed the bip32 extended key types without
leaving the originals in there marked as deprecated. This makes for a
bad experience for devs, add them back in.

Add a feature matrix section to the `bitcoin` CI script as we do in
`hashes`. This means:
- test with no default features
- test with all individual features
- test with all combinations of two features
Note, with this applied all features and optional dependencies are
included in `FEATURES` (excluding `secp-lowmemory`).
The feature matrix test gets run for stable and MSRV toolchains.
Currently `bitcoin` cannot be built with no features enabled, it must
have either "no-std" or "std" enabled. This is an artifact from when
we depended on `core2` for "no-std", now that we have our own `io` crate
and we unconditionally depend on it we can remove the "no-std" feature.
We are emptying the `hash_types` module. `impl_asref_push_bytes!` is an
internal macro, as such it can live in the `internal_macros` module.
While we are at it import the macro and call it without any qualifying
path, this is typical for our usage of other internals/internal_macros
usage.
