We use `internals::hex::display::DisplayHex` in many places, we can
improve ergonomics of the `internals` crate by re-exporting it from the
`prelude` module.
1b0988833a Remove `ToHex` (Martin Habovstiak)
Pull request description:
The `ToHex` trait was replaced by either simple `Display`/`LowerHex` where appropriate or `DisplayHex` from `bitcoin_internals` which is faster.
This change replaces the usages and removes the trait.

089a1e452d Replace `Vec::from_hex` with `hex!` (Martin Habovstiak)

This makes the code less noisy and is a preparation for changing it to `const`-based literal. Because of the preparation, places that used variables to store the hex string were changed to constants.

The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.
IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

This renames `Script` to `ScriptBuf` and adds unsized `Script` modeled
after `PathBuf`/`Path`. The change cleans up the API a bit, especially
all functions that previously accepted `&Script` now accept truly
borrowed version. Some functions that perviously accepted `&[u8]` can
now accept `&Script` because constructing it is no loger costly.
This can be replicated by deleting the `type PackedLockTime = LockTime'
line, and then running
find . -type f | xargs sed -i 's/PackedLockTime/LockTime/g
at the root of the repo.
e00dfa9806 impl FromHexStr for structs with single u32 member (connormullett)
Pull request description:
Closes: #1112
- Adds new trait `FromStrHex` with 2 methods: `from_hex_str` and `from_hex_str_no_prefix`
- Impl new trait on each tuple struct with single u32 member. eg `Time(u32)`
As stated in the issue, grep through codebase with `\(u32\)` and `\(pub u32\)` to see all implementations and verify none were missed.
NonStandardSighashType is an error type and should never be constructed from a hex string. Therefore, it has been omitted from this change.
Tests are somewhat redundant, but cover 4 cases each. 2 happy paths, 1 for each function. 1 case for malformed/invalid hex input, and 1 for calling no_prefix without a prefix

Adds new module `string` to be later converted to its own
crate. The module currently contains the FromHexStr trait and an error
type to be used for implementing hex parsing on types. This change
also adds implementations of FromHexStr for types with a single u32
member such as `Sequence(pub u32)`. All structs that match the
following regex have been given this implementation
`\(u32\)` and `\(pub u32\)`. All implementations have associated
unit tests matching all possible cases. NonStandardSighashType has
been ommitted from this change as it is an error and should not be
constructed using the methods added in this change.
Adds parse::hex_u32 for future use to be made generic to allow
different sizes of integers to be parsed from hex strings.
The error type FromHexError implements required traits such as
Display and std::error::Error
d7006ef80d Adds roundtrip tests for Network::from_core_arg (Sergi Delgado Segura)
bd1eb29f61 Adds Network::to_core_arg (Sergi Delgado Segura)
Pull request description:
Comming from https://github.com/rust-bitcoin/rust-bitcoincore-rpc/pull/247
`Network::from_str` only considers `rust-bitcoin` string as possible inputs to create a `Network` instance. This PR adds a new method to `Network`, `from_core_arg`, which is complementary to the existing `Network::to_core_arg`. This method allows the conversion between `bitcoind -network` string and `Network` variants.
This also links `Network::from_str` to `Network::from_core_arg` so the default case on the former calls the latter, and an error is only returned if none of the cases match.

in the `blockdata` module without considering the content. On review a
bunch of improvements were suggested.
Improve the content of various rustdoc comments in the `blockdata`
module.
Suggested content came from reviewers, all mistakes are my own :)
Reduce the number of lines of code by using a longer column width, 100
as is more-or-less standard in this repo.
This patch only changes column width (line length), no other changes.

Adds method `Work::log2()` providing value equivalent to Bitcoin Core's `log2_work` in its logs. Fixes#1326.
Questions:
- The original issue (#1326) also suggests to add log2 to Target but it does not seem to be meaningful, does it? Bitcoin Core, to which the issue refers, also displays only log2 of work.
- Although work should not be 0, the type allows it. In this case, log2 would return -inf. I think we could leave it like that but if there are suggestions to deal with it in a different way, please let me know.

13d94cbc47 Remove no_run (Tobin C. Harding)
Pull request description:
`no_run` is not needed since we already mark this up as `bash` which rustc doesn't run when running examples.
While the keyword `bash` is not currently supported it may well be in the future and since only the `rust` keyword causes code to run any other string is effectively a wildcard, `no_run` is therefore meaningful only as a convention. Lets keep `bash` in case support is added later on.

In some protocols it is preferred to serialize consensus-encodable types
using consensus encoding. E.g. serialize `Transaction` as hex-encoded
string in Json in Bitcoin Core RPC protocol. This change provides
adapter to make this easier.
The adapter allows providing custom byte-to-string encoder for more
exotic cases and provides a hex implementation which should be useful in
majority of the cases.
Should help with #765

In preparation for removing the `util` module move the `base58` module
to the crate root. This is likely not the final resting place for this
module but it is a step in the right direction.
Includes addition of rustfmt attribute to skip formatting the digits
array. No other changes to the `base58` module.
For some applications, such as block explorers, it's useful to be able
to obtain the public key used in case of P2PK. This is considered
general enough for addition into bitcoin library,
so this change adds it.
The public key is returned only when it's valid and the script is P2PK.
To avoid duplicating the logic checking whether a script is P2PK the
logic is moved to a new p2pk_pubkey_bytes() method which returns raw
bytes and is then called from both is_p2pk() and p2pk_public_key()
We are trying to flatten the `util` module. The `taproot` module can
live in the crate root. If/when we create a `crypto` module/crate we may
wish to pull some stuff out of this module but for now moving it gets us
closer to removing `util` without making the directory structure any
worse.
Includes adding rustfmt attributes to skip formatting of macros.

We just removed the `bitcoin/src/network/` exclude from `rustfmt` config
file. Run the command `cargo +nightly fmt`.
No other changes than those introduced by `rustfmt`.
When we moved to edition 2018 the use of `extern` became unnecessary and
we moved to using `pub use` for re-exports. It was observed however that
`pub extern crate` is more readable.
Improve crate root re-exports by doing:
- Use `pub extern crate foo` to re-export foo.
- Fix docs attribute for optional dependency `bitcoinconsensus`.
- Re-order to how rustfmt would put them.

Ref: https://github.com/rust-bitcoin/rust-bitcoin/pull/672#issuecomment-980636502
[Add Index<usize> and nth(index) to Witness](4226d60205)
[4226d60](4226d60205)
Arbitrary indexing into Witness fixes the API of last and second_to_last to be more flexible.
This patch started off as an addition of third_to_last, but ended up evolving
into arbitrary indexing to allow for future use cases.
A list of the indices of the start byte for each witness element is stored as an ordered
contiguous group of u32s represented as 4 bytes each in the Vec<u8> contents.
The bytes are stored using to_ne_bytes for performance reasons. A helper function is added
to the tests to allow for easier contruction of the contents Vec in test vectors. u32 was
chosen because 22 bits are needed to store 4,000,000 which is the maximum weight limit for
a block. This might need to be reworked in the event of consensus limits increasing, but
u32 can hold 1000x the current limit, so it should be fine for the forseeable future.
The push and consensus_deserialize functions utilize rotate_left and rotate_right to move
the indices to the end of the new allocation. Depending on the size of the data, this
might be more of a performance hit than just allocating a new temporary Vec to store the
indices and append them after parsing is completed. However, for a majority of cases
rotating the indices should be faster. Suggestions to use VecDeque instead of Vec for
contents necessitate other considerations, since it is not a public facing change,
those optimizations can be dealt with in future patches.
The Index<usize> trait is implemented using the new nth method with expect.
The Iter struct is reworked to make use of the new data representation. This new data
structure makes it trivial to implement DoubleEndedIterator and other such traits, but
I have decided to leave this as out of scope for this patch.
---
[Add get_tapscript to Witness](a7501d9599)
[a7501d9](a7501d9599)
This new method will check the last witness element to see if it starts with 0x50, and
depending on the result it will return the second to last or third to last witness
element according to BIP341.
In its current state, Witness can not know what type of script it is fulfilling,
so it is up to the caller to verify if the previous output is a taproot output or not.
---
Edit: This is the previous PR body:
> In a taproot script payment with annex, quick access to the 3rd to last element (which is the actual script in this case) is convenient.
>
> This feels like kicking the can down the road again, but I think it's a nice to have method.
>
> RCasatta dr-orlovsky were discussing this issue. I would like to ask if they have any thoughts on the addition of this.

The `Version` type uses a signed 32 bit integer inner type but we bit
twiddle as if it was a `u32`. We recently made the inner type private to
hide the data type because of this oddness.
Add methods `from_consensus` and `to_consensus` to facilitate any
possible thing users may want to do with a consensus version value.
The Bitcoin block version is a signed integer for historical reasons,
but we bit twiddle it like an unsigned integer and during consensus
encode/decode we cast the signed value to an unsigned value.
In order to hide this confusion, make the inner value private and add a
couple of constants for v1 and v2 block versions.
Currently the types in the block module have longer names than
necessary, "header" and "version" identifiers contain the word "block",
this is unnecessary because we can write `block::Header` instead of
`BlockHeader` when context is required. This allows us to use the naked
type `Header` inside the `block` module with no loss of clarity.
We are stuck with `BlockHash` because the type is defined along with all
the other hash types in `hash_types`, leave it as is for now but
re-export it from the `block` module to assist in putting types that are
used together in scope in the same place, making import statements more
ergonomic.
The `all` module enables usage of a wildcard import statement without
muddying the scope with any other types defined in `opcodes`, in other
words if one wants to use the `All` type `opcodes::All` is the most
clear way to use it, however usage of naked `OP_FOO` types is perfectly
clear.
Add documentation stating that we guarantee to never put anything else
in the `all` module so folks are confident using a wildcard import will
not bring any rubbish into scope.
Expected usage in downstream applications that need types in `opcodes`
as well as the opcodes:
```
use bitcoin::opcodes::all::*;
use bitcoin::opcodes;
```
Also, we do no implement `Ord` or `PartialOrd`, document this including
HTML tags hiding an example bug from Bitcoin Core that shows why not.

b6f9e47dba Fix `no_std` when `bitcoinconsensus` is enabled (Martin Habovstiak)
Pull request description:
`default-features = false` was missing previously but blindly adding it would lead to subtle risk of breaking when a crate not needing `std` depends on `bitcoinconsensus` and simultaneously another crate not needing `bitcoinconsensus` depends on `std` and another crate depends on them both.
This change fixes it by introducing `bitcoinconsensus-std` feature flag and provides a fallback if the flag is off. Unfortunately the fallback has to use a bit of reasonable `unsafe` due to limitations of upcasting.
The only safe alternatives are not do it and provide worse experience for crates that are affected by the problem above or break the API, which couldn't be backported and would be more annoying to use.
Closes#1343
This is considered PoC PR as I realized the possibility of the hack (and necessity of `unsafe`) at the last moment. Things like tests and modifying CONTRIBUTING to change the stance on `unsafe` will be added if `unsafe` is ACKed.

This new method will check the last witness element to see if it starts with 0x50, and
depending on the result it will return the second to last or third to last witness
element according to BIP341.
In its current state, Witness can not know what type of script it is fulfilling,
so it is up to the caller to verify if the previous output is a taproot output or not.
Arbitrary indexing into Witness fixes the API of last and second_to_last to be more flexible.
This patch started off as an addition of third_to_last, but ended up evolving
into arbitrary indexing to allow for future use cases.
A list of the indices of the start byte for each witness element is stored as an ordered
contiguous group of u32s represented as 4 bytes each in the Vec<u8> contents.
The bytes are stored using to_ne_bytes for performance reasons. A helper function is added
to the tests to allow for easier contruction of the contents Vec in test vectors. u32 was
chosen because 22 bits are needed to store 4,000,000 which is the maximum weight limit for
a block. This might need to be reworked in the event of consensus limits increasing, but
u32 can hold 1000x the current limit, so it should be fine for the forseeable future.
The push and consensus_deserialize functions utilize rotate_left and rotate_right to move
the indices to the end of the new allocation. Depending on the size of the data, this
might be more of a performance hit than just allocating a new temporary Vec to store the
indices and append them after parsing is completed. However, for a majority of cases
rotating the indices should be faster. Suggestions to use VecDeque instead of Vec for
contents necessitate other considerations, since it is not a public facing change,
those optimizations can be dealt with in future patches.
The Index<usize> trait is implemented using the new nth method with expect.
The Iter struct is reworked to make use of the new data representation. This new data
structure makes it trivial to implement DoubleEndedIterator and other such traits, but
I have decided to leave this as out of scope for this patch.
This transaction broke past versions of `rust-bitcoin` and LND so this
adds a test to avoid reintroducing the problem in the future.

The `base58` module is for encoding and decoding, it makes sense for the
public functions to be called `encode` and `decode`. We also have some
functions that operate on data with a checksum, for these it makes sense
to tack `check` onto the _end_ of the function name.
With this applied the public API is:
- decode
- decode_check
- encode
- encode_check
- encode_check_to_fmt
Code is arguably easier to read if the most important stuff comes first.
In the old days, when writing C, we had to put definitions before they
were used but in Rust this is not the case
Re-order the `base58` file so that the public API functions are up the top
then other helper functions are defined _after_ they are called.
Refactor only, no logic changes.
Currently we are manually adding `0x` in calls to `write!`, this is
unnecessary since the alternate form already adds the `0x`.
Was verified with
```
#[test]
fn bad_checksum_error_hex_format() {
let want = "invalid base58 character 0xab";
let got = format!("{}", Error::BadByte(0xAB));
assert_eq!(got, want)
}
```
Use alternate form to print hex.
The key related errors are incorrect because they are circular, we have
a base58 error variant in `key::Error` and two key error variants in
`base58::Error`.
Remove the key errors from the `base58::Error` type.
The function call `calculate_root_inline` calculates the merkle root
using the input array as a scratch buffer, i.e., we trash the data
during recursive calls to `merkle_root_r`.
Add explicit documentation to the function so its super clear not to use
the hashes again after calling this function.
Recently we renamed the `hash` module to `merkle_root`, this makes the
public functions provided stutter if used with one layer of path as is
Rust convention:
`merkle_root::bitcoin_merkle_root`
We can improve on this by renaming the functions to 'calculate', then we
get
- `merkle_root::calculate()`
- `merkle_root::calculate_inline()`
The `util::hash` module provides two functions for computing a merkle
root from a list/iterator of hashes.
Rename the module to `merkle_root` and move it to the crate root,
deprecate the original functions.

In preparation for emptying the `internal_macros` module move the

Rationale: `internal_macros` stuff can go over in the `internals` crate
now that we have one. The serde macros could go over there but we have a
`serde_utils` module that holds code for implementing serde traits,
these two macros are exactly that.
`impl_array_newtype` is an internal macro, move it to a new, ever so
meaningfully named, `macros` module.
Use `#[macro_export]`, no other changes to the macro.
Signing a PSBT requires no knowledge other than what we have here in

This code was pulled out of `rust-miniscript`.

them in an attempt to group like things and separate out things that are
different (e.g. `pub use` from `use`).

02a2b43b2b Remove Default impl for Target and Work (Tobin C. Harding)
cb9893c4a9 Add Target and Difficulty types (Tobin C. Harding)
Pull request description:
Ugh! 1600 lines of green and 1100 of red - my apologies.
Currently we use the `Uint256` type for proof-of-work calculations. It was observed in #1181 that providing a public 256 bit integer type like this implies that it is a general purpose integer type. We do not want to provide a general purpose integer type (see the 1000 arithmetic functions on stdlib integer types for why not :)
Add two new opaque integer types `Target` and `Work`. These are the inverse of each other, both conceptually and mathematically.
There is a lot of code in this PR, sorry about that. At a high level the PR does:
- Add a `pow` module.
- Put a modified version of `Uint256` in `pow`, making it private.
- Add two new wrapper types `Target` and `Work` that provide a very limited API specific to their use case. In particular there are methods on each to convert to the other.
- Only implement methods that we use on each type.
### Note
During development I got mixed up with the word "difficulty", I have discovered this has a very specific meaning in Bitcoin. Please see rustdocs on the `Target::difficulty` function for explanation of this term. For this reason we use the type `Work` defined as the inverse of target, and reserve "difficulty" for the Bitcoin concept.

Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).
It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.
- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.
Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.

Move some code out of `misc` then re-name the module to `signature` and move it to the crate root.
- Patch 1: Move a single public function, needs review that destination module is ok. I did consider re-naming the function to remove `script_` prefix but decided to leave it as is.
- Patch 2: Re-names `misc` -> `signature` and puts it in the crate root
- Patch 3: Runs the formatter on `signature` module
All changes include deprecated re-exports.

2001f44e46 Try to fix up sighash export mess (Tobin C. Harding)
Pull request description:
Recently we moved a few types from `transaction` to `sighash`, while doing so I erroneously annotated code with the `deprecated` attribute hoping it would give downstream users a gentle upgrade experience. It turns out `deprecated` only works on functions.
During that same work, we re-exported from the crate root a bunch of types from the `sighash` module that probably should not have been re-exported. We are currently trying to create a nice clean API surface, in an effort to move in the right direction we should remove the re-exports and just re-export the `sighash` module.
Try to clean up the sighash export mess by doing:
- Remove the re-exports from the `transaction` module
- Remove crate level re-exports of `sighash` module types
- Re-export `sighash` module
Note, this patch is a breaking API change, justified by the fact that there is no good way to gently lead downstream when moving types since types cannot be deprecated with the `deprecated` attribute.

34113c9558 Move bip32 module to crate root (Tobin C. Harding)
Pull request description:
We are attempting to flatten the `util` module.
Move the `bip32` module to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter so this move requires `bip32` module to be formatted. Formatting is done as a separate patch so reviewers can run `cargo +nightly fmt` and compare the diffs if so desired.

Pull request description:
Patch 1 is a docs improvement.
Patch 2 commit log:
When implementing the absolute lock time API we decided on _not_
supporting checking lock satisfaction with another lock, instead we
provided a pattern in the docs for doing so. Fast forward a months and
I, the primary author, then forgot to use the correct pattern when using
the API in `rust-miniscript` - this is a sure sign that the API is too
hard to use. In this time we worked on the relative lock API and came up
with a `is_satisfied_by_lock` method - this is identical to the required
use case in the absolute lock time module.
Add a method on `absolute::LockTime` for checking a lock against another
lock, add rustdoc comment explaining the methods function in filtering
prospective lock time values (how we use it in `rust-miniscript`).

The `user_enum` macro is only used a single time. The macro includes
custom serde logic which can be trivially derived instead.
Remove the `user_enum` macro and just implement `Network` the old
fashioned way. Doing so simplifies the code.
We are attempting to flatten the `util` module; move the `bip32` module
to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter, this patch does not
do formatting, will be done later.
The lock time methods are a source of endless confusion; make an attempt
at improving further the documentation on the two `is_implied_by`
methods (one on absolute lock time and one on relative).
As we just did for `absolute::LockTime` add a method `is_implied_by` and
deprecate `is_satisfied_by_lock`.
Reasoning: it is odd to think of a lock satisfying another lock but it
is clear to see that satisfaction of one lock can imply satisfaction of
another.

We have a function in `util::misc` that operates on scripts, it is an
implementation of `FindAndDelete` from Bitcoin Core and is primarily
useful for supporting `CODESEPARATOR`, which we do not support.
Move the public `script_find_and_remove` function out of `util/misc.rs` and into
`util/mod.rs`, delete the testing and deprecate the function.

`ChainHash::using_genesis_block` can't be made `const` because it uses a
`match` expression, which is only valid in Rust 1.46. Add individual
constants as a workaround so that `ChainHash` can be used in `const`
contexts.
We give one release cycle for deprecating old code so as to make the
upgrade path easier for downstream users.
Remove code deprecated during the last release (v0.29.0).
Currently we attempt to have deprecated key types in the `schnorr`
module. The `deprecated` attribute does not work on types, only on
functions.
Remove the broken deprecation logic and re-export key types instead of
using type alias', this allows a bunch of qualified paths to be
simplified also.
Add `pub use` re-exports of all secp256k1 types that are part of the
public API of the `schnorr` module. This makes the module more ergonomic
to use.
When filtering it is necessary to check two lock times against each
other, we currently provide a patter for doing so in the docs but we can
do better.
It was observed that satisfaction of a lock time 'implies' satisfaction
of another lock time if the lock times are the same unit and one locks
value is less than the others - this is exactly the code pattern we
suggest for filtering.
Add a method on `absolute::LockTime` for checking a lock against another
lock, add rustdoc comment explaining the methods function in filtering
prospective lock time values (how we use it in `rust-miniscript`).
Currently in one of the rustdoc examples showing lock satisfaction we
use two locks with the same value, this obfuscates which lock is doing
the satisfying and which lock is being satisfied.
Increment the value in one of the locks so it is obvious which lock is
which.
Add a new crate `bitcoin-internals` to be used for internal code needed
by multiple soon-to-be-created crates.
Add the `write_err` macro to `bitcoin-internals`, nothing else.
This patch uses a `path` dependency which means `rust-bitcoin` cannot be
released in its current state, will need to be changed once we release
the `bitcoin-internals` crate on `crates.io`.
Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
