Merge rust-bitcoin/rust-bitcoin#2896: Move `PushBytes::read_scriptint` outside of the `private` module
aebf216619 Use 100 column width for rustdoc (Tobin C. Harding)
c71ae9ac16 Move PushBytes::read_scriptint (Tobin C. Harding)

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.

  Patch 2 is whitespace only.

Use 100 column width for rustdoc
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.

No text changes, only whitespace.

merkle_node: rewrite algorithm
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.

merkle_tree: introduce MerkleNode trait to better-type merkle tree calculation 2024-06-17 19:10:26 +00:00
Andrew Poelstra 5d8aa94069
Move merkle_tree hash types
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.

  Fixes #2849

  There were a few other usages of PushBytes::read_scriptint(_) in the tests such as [this](406e3486ab/bitcoin/src/blockdata/script/tests.rs (L315)), but they couldn't be updated as cleanly as the changes in this PR.

Enforce script size limit when hashing scripts
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

Rename p2wsh script to witness_script
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.

Remove odd script hash test
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.

6b7d02e5ae Add inherent functions to hashes (Tobin C. Harding)

Pull request description:

  Currently we have a trait `Hash` that is required for `Hmac`, `Hkdf`, and other use cases. However, it is unegonomic for users who just want to do a simple hash to have to import the trait.

  Add inherent functions to all hash types including those created with the new wrapper type macros.

  This patch introduces some duplicate code but we are trying to make progress in the hashes API re-write. We can come back and de-dublicate later.

  Includes making `to_byte_array`,`from_byte_array`, `as_byte_array`, and `all_zeros` const where easily possible.

Pull request description:

  - Use `*_byte_array` for the names instead of `*_bytes`

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

code is enabled if any downstream crate tries to build with
`--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.

802af8e417 Removed //! spare line at end of headers (jamil.lambert)

Pull request description:

  Some of the headers had a //! at the end but most didn't.  They have all been removed in bitcoin/src/ to make the files consistent

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.

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

Improve deprecation notice
The deprecation notice for `is_provably_unspendable` contains "is not
very useful" which is a bit presumptuous to tell to users, it may very
well be useful to them. Use the more helpful text that already exists in
rustdoc on the function.

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.

Pull request description:

  When computing the maximum difficulty transition threshold we forgot to check that the returned `Target` is not bigger than the maximum. This value is network specific so keep the original logic but with `_unchecked` on the function name.

  This was noted in the discussion on #2161

Take Params instead of Network in difficulty function
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`.

Merge rust-bitcoin/rust-bitcoin#2581: Implement ArbitraryOrd for relative::LockTime
d91cdd20bf docs: Document ordered feature (Tobin C. Harding)
3520f550f0 Implement ArbitraryOrd for relative::LockTime (Tobin C. Harding)

Pull request description:

  TL;DR As we do for `absolute::LockTime` and for the same reasons; implement `ArbitraryOrd` for `relative::LockTime`.

  locktimes do not have a semantic ordering if they differ (blocks, time) so we do not derive `Ord` however it is useful for downstream to be able to order structs that contain lock times. This is exactly what the `ArbitraryOrd` trait is for.

  Fix: #2566
