Currently `combine_node_hashes` is an associated function, it is also
private. It is called from within other methods of the `TapNodeHash`.
In preparation for moving the `TapNodeHash` to `primitives` while
leaving all the methods in `bitcoin` in an extension trait; move the
associated function out of `TapNodeHash` and make it a stand alone
private function.

Tree-SHA512: 365979aeabb7941b9c8fa526f71aaadae3ab1cdd6a39e992c5eea2c1057b4b7c2b3a846ffd96a7eab47b9ad4e3e4de4fb141c24c62747e5cee45c74f52f9a172
The `DecodeError` (badly named) consensus decodes an object from an
iterator that implements `Read`. The `Read` impl never returns a real IO
error, we use the `io::Error` to temporarily wrap the error returned by
the inner iterator and unwrap it in `IterReader::decode`. As such there
is no reason for the `DecodeError` to hold an `encode::Error`, it can
hold an `encode::ParseError`.
The value of this change is easily seen in the removal of calls to
`unreachable`.
The `consensus::encode::Error` contains an IO error but reading from a
buffer only ever errors for EOF. We converted all instances of EOF to
`MissingData` already so now we can split the IO error apart from the
actual encoding errors variants.
The `io::Error` is troublesome because it contains a bunch of stuff that
never happens when reading from a buffer. However the EOF variant can
occur if the buffer is too short. As an initial step towards reducing
usage of the `io::Error` add a `MissingData` variant to the
`encode::Error` and when converting from an IO error map to
`MissingData` if EOF is encountered.
The `encode::Error::ParseFailed` variant holds an inner string, this is
suboptimal.
In an effort to patch the `encode::Error` while mimizing the diffs
required add a helper function that creates the variant. The benefit is
that later patches that effect this variant will only need to update the
constructor function and not every call site.
Internal change only.
The `consensus` module has a bunch of error types, move them all to a
separate module. Add re-exports so the types are still available at the
same place they were. Make the `error` module private and re-export all
errors from the `consensus` module root.
ParseError is too general and the functions returning it do not have an
error path for all variants.
Split out the Bech32 and Base58 related errors into their own enums.
The extension traits are temporary just while we try to stabalize
`primitives`, they are not intended to be implemented by downstream.
Seal the extension traits so that downstream crates cannot implement
them.

When a decoding error occurs for a bech32 address string the error is
discarded and the same address string is attempted to be decoded as
base58. This then incorrectly returns a base58 error.
Check the string prefix and decode as bech32 or base58 and return the
relevant error. If the prefix is unknown return an `UnknownHrpError`.
Move the `Witness` over to `primitives` leaving behind any method that
takes or returns a `Script` or a signature.
Includes addition of a feature gate to unit test.
In preparation for moving the `Witness` to `primitives` we need a way to
construct the `Witness` when decoding. In order to maintain the current
performance and not introduce additional allocations we need to be able
to construct a `Witness` from the content buffer, this leaks the
implementation details of `Witness`.
Add a clearly marked unstable constructor to create a `Witness` from
parts. This introduces the concept of `foo__unstable` function names;
add a section to the README describing unstable functions and semver
guarantees.

We want to move the `block_hash` function to `primitives` but it uses
`Encodable` which currently lives in `bitcoin`. Just implement it
manually.
We added a regression test already in a previous commit to check that
this is correct.
We use `TBD` in our `deprecated` string and it was discovered that there
is an exception on this string so as not to warn because it is used
internally by the Rust language. However there is a special lint to
enable warnings, lets use it.
Add `#![warn(deprecated_in_future)]` to the coding conventions section
of all crates except `fuzz`.
We had an initial go at this but we didn't do the `Hash` trait method.
In order to do so we need to hack the serde code a fair bit, note the
public visitor types.
Recently we deprecated `to_vec` in favour of `to_bytes` however we
continued to use `to_vec` in a few places. This wasn't noticed because
of our usage of `TBD` in the `deprecated` attribute.
Use `to_bytes` instead of `to_vec`.

We would like to move the `Witness` to `primitives` however in the
`Encodable` implementation we are currently accessing the private
`content` field.
Instead of accessing `content` we can iterate over the witness elements
and write each individually, this has the same result but does a bunch
of additional calls to `Write::write_all` (via `emit_slice`).
This patch effects performance negatively but makes no changes to the
encoding.
The `Witness::push_slice` function is called by `Witness::push` after
calling `as_ref`, hence is equivalent for all types that implement
`AsRef<[u8]>`. Also, `push_slice` is a private method on `Witness`.
In preparation for moving `Witness` over to `primitives` stop using
`push_slice` in favour of `push`.
Internal change only.
In preparation for moving the `Witness` oven to `primitives` use the
`len` function instead of accessing the `witness_elements` field.
No logic change, `Witness::len()` returns `witness_elements`.

Pull request description:
Adds `Xpriv::to_xpub` and makes naming of methods related to extended and non-extended keys on `Xpub` and `Xpriv` consistent and easier to discover:
- if method takes or returns extended key, its name uses `xpriv` or `xpub`
- if method takes or returns non-extended key, its name uses `public_key` or `private_key`
Previous naming of the methods was confusing and unclear and this PR deprecates them.
Closes#3327.
### Notes for reviewers
- `xpriv` and `xpub` could be without `x`, I opted for this version to remove any ambiguity
- also considered `raw` or similar name (as suggested) for methods with non-extended keys, however `raw` is usually not used in this context and `to_public_key` vs. `to_x_only_public_key` did not look alright with any other name
- if splitting this PR into two would be desirable, please let me know
- is there a reason why `ckd_priv` is private and `ckd_pub` is public?

This change makes method names on Xpub and Xpriv more consistent and
easier to discover by following two patterns:
- if the method deals with extended key, it contains 'xpub' or
'xpriv' in its name
- if the method deals with non-extended key, it contains
'public_key' or 'private_key'
One exception is 'ckd_*' methods, which are lower-level and their names
come from BIP32; these keep using 'priv' and 'pub'.
Move the `OutPoint` type and associated code over to `primitives`. Take
the opportunity to re-order the code so the file reads like a story,
things are implemented below where they are called.
Our `define_extension_trait` macro cannot handle examples in rustdocs,
since these docs are on the deprecated `OutPoint::is_null` function just
remove them.
In preparation for moving the `OutPoint` to `primitives` add an
additional impl block that holds everthing that will stay here in
`bitcoin`.
Internal change only.
Rust convention is to not use `test_` prefix on unit tests. Also this
unit test is testing that the `ExactSizedIterator` trait is implemented
and working.
Re-name unit test to `exact_sized_iterator`.
In preparation for moving unit tests to `primitives` give the serde
tests some love by doing:
- Split them up to do one thing only
- Round trip arbitrary witness
- Use better names
Make an effort to clean up the encoding unit test, by doing:
- Remove element accessor assertions (tested already above)
- Add roundtrip encoding assertion
33edaf935d fix: check overflow for push_int with push_int_unchecked (Chris Hyunhum Cho)
876146154b refactor: use push_lock_time instead of push_int (Chris Hyunhum Cho)
Pull request description:
Fix the issue https://github.com/rust-bitcoin/rust-bitcoin/issues/1530. In the discussion of https://github.com/rust-bitcoin/rust-bitcoin/issues/1530, the suggested solution is to implement `ScriptInt` type to embrace the various type of integer(`i32, u32, i64, u64, i128, u128, isize, usize...`) to support both script number and locktime number.
However, as `push_locktime` and `push_sequence` implemented, there’s no need to support `u32` of lock time for `push_int` anymore. Therefore, I’ve just changed the type of parameter to `i32`, and only check if it’s `i32::MIN`(which overflows 4 bytes sign-magnitude integer).
~I also added push_uint method to use internally for `push_locktime` and `push_sequence`, which have a dependency on `push_int` method.~
UPDATE: also add `push_int_unchecked` for those who want to push the integer out of range(and helper for `push_locktime` and `push_sequence`, which has the same functionality of former `push_int`.

The current unit test is incorrect, the indices field of a witness with
a single element starts at 1 because 0 is encode as a single
byte (compact encoded integer).
Fix the debug test and add a test that pushes an empty slice.
Recently we removed the `all_zeros` function from `OutPoint` in favour
of a more meaningfully named associated const. We can do the same for
`BlockHash`, the all zeros has is used for the previous blockhash of the
genesis block, add a const named as such.
In test code where we use the `all_zeros` function, just use the more
explicit form `from_byte_array([0; 32])`.
Currently we provide `Default` implementations for a couple of types in
the `transaction` module, the values returned are meaningless and it
seems these impls were added to make writing test code easier. In
hindsight this was the wrong thing to do.
Break the API and remove the `Default` implementations for `OutPoint`
and `TxIn`.
Add an associated const `TxIn::EMPTY_COINBASE` that is, as the name
suggests, an empty transaction input with the prevout set to all
zeros as for the coinbase transaction.
At some stage we named the compact encoding `VarInt` (which makes sense
because the compact size encoding is a variable length integer encoding).
However it turns out the term "varint" is used in Core for a different
encoding so this may lead to confusion.
While we fix this naming thing observe also that the `VarInt` type is
unnecessarily complicated, all we need to be able to do is encode and
decode integers in compact form as specified by Core. We can do this
simply by extending our `WriteExt` and `ReadExt` traits.
Add `emit_compact_size` and `read_compact_size` to emit and read compact
endcodings respectively.
Includes addition of `internals::compact_size::encoded_size_const`.
Patch originally written by Steven, Tobin cherry-picked and did a bunch
of impovements after the varint vs compact_size thing (#1016).

We would like to add a `emit_varint` function, however doing so requires
that we can get access to the length of a slice when we are encoding it
so we can use `emit_slice` to implement `emit_varint`. It would be
easier to do so if `emit_slice` returned the length of the slice.
In preparation for adding `emit_varint` (and removing the `VarInt` type)
return the encoded length of a slice from `WriteExt::emit_slice`.

8ec3571d80 Implement GetKey for Vec<Xpriv> (Nadav Ivgi)
Pull request description:
It appears that the `BTreeSet<Xpriv>`/`HashSet<Xpriv>` sets currently implementing `GetKey` cannot actually be constructed, because `Xpriv` does not implement `Ord` nor `Hash`. (And that the rust-bitcoin code referencing these sets should not even compile? yet evidently it does 👀 )
This PR adds support for `Vec<Xpriv>` to enable signing with multiple `Xpriv`s, but does not address the issue with the existing sets.
The added test case demonstrates the issue:

Pull request description:
- The first commit is the simplest fix for a bug where the fingerprint wasn't compared correctly.
- The second & third commits are optional refactoring to reuse `Xpriv::get_key` for `$set<Xpriv>::get_key`, so the Xpriv matching logic only has to be maintained in one place.
- The forth commit adds support for signing with `Xpriv`s that are direct children of the `KeySource` -- possibly what the original (buggy) code author had in mind?
Of course, feel free to take just the first commit if the others seem unnecessary. The last one is kind of meh, not sure if really useful.
Note that multi-`Xpriv` signing does not actually work until #2850 is addressed too.

The `Builder` is staying in `bitcoin` while the `ScriptBuf` is moving to
`primitives`, so we cannot access the inner field of `ScriptBuf`.
Use the new `as_byte_vec` hack to mutate the inner `ScriptBuf` field.
In preparation for moving the `ScriptBuf` type to `primitives` stop
accessing the inner field when encoding/decoding, use `as_script`
and `from_bytes` instead.
In preparation for moving the `Script` type to `primitives` stop
accessing the inner field before doing slice operations, use `as_bytes`
to first get at the slice.
The `Script::fmt_asm` function is a legacy from days yore before
`Display` printed asm. We no longer need it.
Deprecate `Script::fmt_asm` and use the private `bytes_to_asm_fmt` or
`Display` impls.
Use the `define_extension_trait` macro to define two extension traits
for the two txid types. Each trait holds the deprecated `all_zeros`
function. There are no users of this trait in the code base.
Recently we deprecated the `all_zeros` functions on `Wtxid` and
`Txid` but for some reason our usage of them is not triggering a lint
warning.
Note please that this changes logic slightly, for example by using an
array of `0xFF` bytes instead of all zeros. Done in an effort to make it
even more obvious that the value is a dummy value and not mix it up with
the all zeros being used for coinbase thing.
In #3308 we added associated consts to the `Txid`, `Wtxid`, and
`OutPoint` types. During review and afterwards we realised the docs
could do with improving. Since we now want to move the types we should
do this first.
Close: #3331
Instead of accessing the inner type of a hash wrapper type when
consensus encoding we can call `as_byte_array()`.
Done in preparation for moving `Txid` and `Wtxid` to `primitives`.
Internal change only.

The `UintError` type (returned by `read_uint_iter`) is not that useful
because one variant is unreachable. Re-write the function by doing:n
- Re-write the function to reduce the error cases returned.
- Re-name it to `read_push_data_len`
- Move it to `internals`
- Use `PushDataLenLen` enum instead of an int parameter

a20d0bc4eb Deprecate `from_slice()` in sha256.rs (Jamil Lambert, PhD)
089043546f Deprecate `from_slice` methods in favor of arrays (Jamil Lambert, PhD)
Pull request description:
As brought up in issue #3102 support for Rust arrays is now much better so slice-accepting methods that require a fixed length can be replaced with a method that accepts an array.
`from_slice()` methods that require a fixed length have been deprecated and where needed a `from_byte_array()` method created that accepts an array.
There are still `from_slice` methods that rely on changes to external crates before they can be changed to arrays.

`from_byte_array` cannot error due to InvalidLength so the returned
MessageSignatureError has been changed to return a secp256k1::Error,
which is the only error type returned by the function.
Support for Rust arrays is now much better so slice-accepting methods
that require a fixed length can be replaced with a method that accepts
an array.
`from_slice()` has been deprecated and replaced with `from_byte_array()`
Currently we have `all_zeros` functions and `null` functions but we can
do better.
Add associated consts and improve the names to better describe what
these dummy zero hashes are used for.
Deprecate related functions.
In release mode we have a few unused variable warnings, lets just
allow them.
Found when running bench code, interestingly `cargo bench` must build
in release mode.
We would like to move the witness module to `primitives` but there is
a bunch of usage of `VarInt`.
Introduce a module that does the encoding and decoding instead, this
code is internal so put it in `internals`.
Note we add an unused public `MAX_ENCODABLE_SIZE` variable that is
commented with an issue link. Done like this because its quite
important that we see to it and it makes it clear that we are not and
we know about it.

We would like to move the `Transaction` type to `primitives`, as a step
towards this move the `transaction::Version` and its trait imps (just
`Display`) over there.
In preparation for adding an extension trait; separate the
`transaction::Version` impl blocks into stuff that will stay here and
stuff that will go to `primitives`.
Refactor only, no logic changes.

Created a macro that implements `to_hex` for types that currently have `core::fmt::LowerHex` and called it on types that have `core::fmt::LowerHex` implemented. I put the macro in the `internals` crate since there are types across the whole project that can potentially use this.

9db6234ea9 Show compressed public key in Debug for CompressedPublicKey (Jiri Jakes)
Pull request description:
Currently `CompressedPublicKey` debug produces output of form:
```
CompressedPublicKey(PublicKey(2f8b18dc0adcb73d75f7934d9523ea7347083e41c48115398cb37e295a0a6ffe86e0bf8b1ef65888c880c8d8813a30e69e466380cbe2daec18f3ed1e7a553ff2))
```
Although it shows real internal structure together with inner uncompressed public key, it is not too helpful for the purpose of debugging _compressed_ public key.
After this patch, `Debug` output will be equal to `Display` (it, in fact, delegates rendering to `Display`), prepended by the name of the struct:
```
CompressedPublicKey(02fe6f0a5a297eb38c391581c4413e084773ea23954d93f7753db7dc0adc188b2f)

cf129ad314 fix: re-implement (de)serialization from/to readers/writers (elsirion)
Pull request description:
Fixes#3250.
The serialization is less than ideal and still allocates a lot. I can understand not wanting to (ab)use the consensus encoding traits, but they have a pretty good interface, copying it and creating some `EncodePsbt` and `DecodePsbt` traits with similar interfaces would have been nice imo.

Pull request description:
As mentioned in issue #3234 `s.parse::<T>()` is more idiomatic and produces more helpful error messages.
This has been changed in the main codebase, not including examples, rustdocs, and in the `test` modules.
`use std::str::FromStr;` has been removed where this change makes it unnecessary.
To close the issue it may also need to be changed in the examples and the `test` modules and `contributing.md` updated.

`s.parse` is more idiomatic and produces more helpful error messages.
This has been changed repo wide in the main codebase, not including
examples, rustdocs, and in the test module.
`use std::str::FromStr;` has been removed where this change makes
it unnecessary.
The two `TxOut` fields are public and there are no construtors or
getters to move, only the associated const `NULL`.
Add a tmp module around the big impl block so we can trick the formatter
into indenting before we add the extension trait.
3e034d5ede Add Arbitrary dependency (yancy)
Pull request description:
Adds an example draft showing what is needed to use Arbitrary for coin selection.
Shot out to how nice Arbitrary is for fuzzing a target by taking unstructured randomness and creating structured rust-bitcoin types for fuzzing. Is there a way we could add this to rust-bitcoin for structuring the fuzz data needed?
This is then the example to fuzz test a SRD algo (after applying this PR to rust-bitcoin) using rust-bitcoin types :)
```

9fb5edb39e ecdsa: Improve error types (Tobin C. Harding)
Pull request description:
There are a couple of issues around the ECDSA signature decoding / parsing code. We have duplicate code in `from_str` and `from_slice` and both use the same error type even though it is impossible to get a hex error in `from_slice`.
Create two errors:
- A `DecodeError` returned by `from_slice`
- A `FromStrError` that has a decode variant and a hex variant
Call through to `from_slice` after parsing hex into a byte vector.
Removes an instance of `unreachable!`.
