Merge rust-bitcoin/rust-bitcoin#912: Improve docs in taproot module
c25eddd187 Remove unnecessary documentation (Tobin Harding)
8631474f08 Improve docs in taproot module (Tobin Harding)

Pull request description:

  I should have done this PR a month ago, my bad. This one is kind of important IMO because we are going to have so many people looking at this part of the code soon as we release.

  As has been done in other places in the codebase; improve the docs in the `taproot` module by doing:

  - Use full sentences (capital letters + full stops)
  - Use back ticks and links for types where appropriate
  - Fix grammar
  - Fix stale docs
  - Use third person for describing functions
  - Use 100 character line width
  - Use markdown sections (`# Examples`, `# Returns`) where appropriate
  - Separate brief heading from extended description when appropriate
  - Use `///` for all functions/types (both private and public)

  I also did:

  - Build the docs and check all the links
  - Read all the built docs, check for sanity and pretty-ness

  Its all in one patch, I couldn't really tease it apart. I can try a bit harder if it proves too annoying to review.

Pull request description:

  The newly introduced `PsbtSigHashType` uses very different serde formatting from previously used `EcdsaSigHashType`; for instance it does not output human-readable sighash. This is especially obvious when printing out PSBT as JSON/YAML object and is a breaking change from the `0.27`. Serde human-readable implementation requires `Display/FromStr`, which were also absent.

Merge rust-bitcoin/rust-bitcoin#839: feat: Add Address.is_related_to_*_key()
51fef76129 feat: Add Address.is_related_to_pubkey() (Andrew Ahlers)

Pull request description:

  ## Motivation

  This is addressing the second half of this comment: https://github.com/rust-bitcoin/rust-bitcoin/pull/684#issuecomment-1012136845

  > but would accept a PR (or two PRs) that returns Result<bool, UnsupportedAddress> and a method to check if a PublicKey is associated with an address.

  (The first half was addressed [here](https://github.com/rust-bitcoin/rust-bitcoin/pull/819))

  These changes will help build out and improve message signature verification. We don't necessarily need to add it to this crate but it allows for easy verification with something such as:
  1. recovering a pubkey
  2. checking if that pubkey relates to the given address

  ## Possible Improvements

  - There is likely a better name than `is_related_to_secp256k1_key()`
  - This could drop the `secp256k1` part of the name and take in a Pubkey enum that also supports Schnorr pubkeys and then this could be used for taproot addresses as well. This felt like a much larger change that will likely get turned down. Verifying taproot is simple enough and if absolutely desired, similar functions can be added for schnorr keys (tweaked and untweaked)

Pull request description:

  Implemented after @sanket1729 suggestion in https://github.com/rust-bitcoin/rust-bitcoin/issues/895#issuecomment-1074366108

  Iterates all scripts present in TapTree in DFS order returning `(depth, script)` pairs.

  I propose to have it as an RC fix since this functionality is really lacking and may be required for many wallets working with Taproot PSBT even outside of the scope where I originally needed it (OP_RETURN tweaks for TapTree described in #895)

Tobin Harding e05776f176 Improve PsbtSigHashType conversion methods
Improve the `PsbtSigHashType` conversion methods by doing:

- Re-name `inner` -> `to_u32` as per Rust convention
- Add `from_u32` method

Note, we explicitly do _not_ use suffix 'consensus' because these
conversion methods make no guarantees about the validity of the
underlying `u32`.
2022-03-28 10:43:37 +11:00
Tobin Harding ac462897b1 Remove hungarian-ish notation
The functions `from_u32_standard` and `from_u32_consensus` smell a bit
like hungarian notation. We can look at the method definition to see
that the methods accept `u32` arguments without mentioning that in the
method names.

Remove `_u32_` from the method names. This brings the `from_*` methods
in line  with the `to_standard` method also.
2022-03-28 10:43:37 +11:00
Tobin Harding d1753d7ff1 Rename as_u32 -> to_u32
Rust naming conventions stipulate that conversion methods from owned ->
owned for `Copy` types use the naming convention `to_`.

This change makes the function name objectively better, however it makes
no claims of being the 'best' name. We have had much discussion on using
`to_standard` vs `to_u32` but are unable to reach consensus.

Tobin Harding 1629348c24 Use conventional spacing for default type parameters
The exact code formatting we use is not as important as uniformity.
Since we do not use tooling to control the formatting we have to be
vigilant ourselves. Recently I (Tobin) changed the way default type
parameters were formatted (arbitrarily but uniformly). Turns out I
picked the wrong way, there is already a convention as shown in the rust
documentation online (e.g. [1]).

Use 'conventional' spacing for default type parameters. Make the change
across the whole repository, found using

    git grep '\<.* = .*\>'

Martin Habovstiak 4f1200d629 Added `amount::Display` - configurable formatting
This significatnly refactors the amount formatting code to make
formatting more configurable. The main addition is the
`amount::Display` type which is a builder that can configure
denomination or other things (possibly more in the future).

Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.

Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.

  This should be straightforward. Let me know if there are any style issues. I tried to keep things similar to the existing test while cutting out any extra cruft to keep things small.

Update secp256k1 dependency
Update our `rust-secp256k1` dependency to the latest version.

Requires doing:

- Add a new variant to `Error` for the case where parity of the internal
  key is an invalid value (not 0 or 1).
- Use non-deprecated const

Andrew Ahlers 51fef76129 feat: Add Address.is_related_to_pubkey() 2022-03-06 20:30:22 +01:00
sanket1729 91c5d7192f Change the parameter for control block verification
Changes the API from TweakedPublicKey to XonlyPublicKey. I believe we
introduced TweakedPublicKey to guard against creating address API. This
is confusing because when we want to verify control block we have to
call dangerous_assume_tweak.
This is in true in most cases that the key would be tweaked, but we only
want to guard in while creating a new address. If we want to verify
blocks, we should deal with native X-only-keys regardless of how they
were created

Merge rust-bitcoin/rust-bitcoin#842: Separate out merge method into public trait
5e2449922d Separate merge logic out of Map trait (Tobin Harding)

Pull request description:

  Recently we (*cough* Tobin) made the `Map` trait private and neglected
  to add a public API for merging together two PSBTs. Doing so broke the
  `psbt` module.

  Add a public trait `Merge` and implement it for
  `PartiallySignedTransaction` using the code currently in the `merge`
  method of the now private `Map` trait.

c0d36efb8b Don't allow uncompressed public keys without prefix 0x04 (Noah Lanson)

Pull request description:

  Was following #520 and through it was a quick fix that I could do:

  #### Changes:
  - If an uncompressed public key doesn't have prefix 0x04 in `PublicKey::from_slice()`, an error is returned.

  <br>

  I was wondering if `PublicKey::from_str()` should also enforce the same rules, however I have not incuded this in the PR.

  Please let me know if any changes need to be made.

Separate merge logic out of Map trait
Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.

Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.

Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.

  Rationale: bitcoin key types are not specific for signature algorithm. See discussion at #588.

  This PR became possible after we moved on new `secp256k1` version exposing `XonlyPublicKey` type, since now all key types may co-exist in a single module under different names

  The PR goal is achieved through
  - Renaming ecdsa mod into private ec module such that the code is not copied and diff size is small;
  - Introducing dummy ecdsa mod back in the next commit and re-exporiting only signature types from internal `ec` mod in it;
  - Re-exporting all key types under `key` module, removing previous depreciation message for bitcoin keys.

Pull request description:

  The original `LeafVersion` implementation was just a newtype around `u8`. I think that having enum explicitly listing consensus script implementation rules may be more beneficial in terms of both code readibility and future use of multiple script types, where `LeafVersion` may operate as a context object provided to `Script` to specify interpretation rules for particular op codes.

Pull request description:

  In the first two commits I moved some data from source files to the newly introduced `test_data` dir, including it with `include_[str|bytes]!` macro.

  The second-to-last commit introduces a big block in test_data which is very handy in ser/de benchmark (I used it for #672) because with smaller blocks you may not notice performance improvements.

  Since I don't want to pollute the package the last commit excludes the `test_data` dir from the published package. I think it's fine to do it because dependent packages don't run dependencies tests.

Merge rust-bitcoin/rust-bitcoin#672: New Witness struct to improve ser/de perfomance
106acdc3ac Add fuzzing for Witness struct (Riccardo Casatta)
2fd0125bfa Introduce Witness struct mainly to improve ser/de performance while keeping most usability. (Riccardo Casatta)

Pull request description:

  At the moment the Witness struct is  `Vec<Vec<u8>>`, the vec inside a vec cause a lot of allocations, specifically:

  - empty witness -> 1 allocation, while an empty vec doesn't allocate, the outer vec is not empty
  - witness with n elements -> n+1 allocations

  The proposed Witness struct contains the serialized format of the witness. This reduces the allocations to:

  - empty witness -> 0 allocations
  - witness with n elements -> 1 allocation for most common cases (you don't know how many bytes is long the entire witness beforehand, thus you need to estimate a good value, not too big to avoid wasting space and not too low to avoid vector reallocation, I used 128 since it covers about 80% of cases on mainnet)

  The inconvenience is having slightly less comfortable access to the witness, but the iterator is efficient (no allocations) and you can always collect the iteration to have a Vec of slices. If you collect the iteration you end up doing allocation anyway, but the rationale is that it is an operation you need to do rarely while ser/de is done much more often.

  I had to add a bigger block to better see the improvement (ae860247e191e2136d7c87382f78c96e0908d700), these are the results of the benches on my machine:

  ```

  With an increased performance to deserialize a block of about 21% and to serialize a block of about 16% (seems even higher than expected, need to do more tests to confirm, I'll appreciate tests results from reviewers)

Introduce Witness struct mainly to improve ser/de performance while keeping most usability.
Witness struct is in place of the Vec<Vec<u8>> we have before this commit.

from_vec() and to_vec() methods are provided to switch between this type and Vec<Vec<u8>>

Moreover, implementation of Default, Iterator and others allows to have similar behaviour but
using a single Vec prevent many allocations during deserialization which in turns results in
better performance, even 20% better perfomance on recent block.

last() and second_to_last() allows to access respective element without going through costly Vec
transformation

Allow specifing a raw `TapLeafHash` in sighash computation
Instead of always requiring the full raw script and leaf version, allow
just specifying a raw leaf hash to the sighash computation functions.

This is very useful when dealing with PSBTs, because the
`PSBT_IN_TAP_BIP32_DERIVATION` field only maps a public key to a leaf
hash, so a signer could just take it and produce a signature with it
rathern than having to jump through hoops to recover the full raw

f690b8e362 Be more liberal when parsing Denomination (Tobin Harding)
628168e493 Add missing white space character (Tobin Harding)

Pull request description:

  There is no reason to force users to use a particular format or case for `Denomination` strings. Users may wish to write any of the following and all seem reasonable
  - 100 sats
  - 100 sat
  - 100 SAT

  The same goes for various other `Denomination`s.

  - Patch 1 enables usage of "sats", "sat", "bit", "bits"
  - Patch 2 enables usage of various lower/uper case formatting

  Fixes: #729

Tobin Harding f690b8e362 Be more liberal when parsing Denomination
There is no reason to force users to use one particular form when
providing a denomination string. We can be liberal in what we accept
with no loss of clarity.

Allow `Denomination` strings to use a variety of forms, in particular
lower case and uppercase.

Note, we explicitly disallow various forms of `Msat` because it is
ambiguous whether this means milli or mega sats.

Pull request description:

  ~Do two minor refactorings to the `bitcoin_merkle_root[_inline] functions.~

  This PR has grown, is no longer a refactoring because the two functions have been changed to return an `Option`.

  First patch is cleanup. Here is the commit message for the second patch
  ```
  The merkle_root of an empty tree is undefined, this is the only error
  case we have for the two `bitcoin_merkle_root*` functions. We can fully
  describe this error case by returning an `Option` if args are found to
  be empty.

  While we are at it, refactor out a recursive helper function to make
  reading the code between the two functions easier.

  Please note, I saw this was labeled 'good-first-issue' but I ignored that and greedily implemented a solution because of two reasons
  1. We want to get taproot stuff done post haste.
  2. I'm struggling to follow what is going on with all the taproot work so this seemed like a way to get my hands dirty.

Tobin Harding 3c3cf0396b Remove use of unreachable in error branch
We currently run `tweak_add_check` and use the result as a conditional

`unreachable` is non-typical. An 'unreachable' statement is by
definition supposed to be unreachable, it is not clear why we would need
to have a conditional branch to check an unreachable statement.

Use `debug_assert!` so programmer errors get caught in un-optimised
builds but in optimised builds the call to `tweak_add_check` is not even
done.

Pull request description:

  I noticed one cleanup & one bugfix while looking into the huffman algorithm:

  1) the cleanup: we can use a u128 to guarantee no overflows, and saturating_add to guarantee reasonable behavior in any case
  2) the bug: the binary heap is a max heap so the behavior ends up merging the nodes of the most likely entries repeatedly. a huffman encoder requires merging the least likely elements, so it should be reversed.

  - Use 100 character line length
  - Do grammar fixes
  - Use comment sections (e.g. `# Returns`)
  - Use 3rd person for function comments e.g. 'Converts foo to bar' instead of 'Convert foo to bar'
  - Use ticks for scriptPubkey

  This patch does a single file because a bunch of these changes pick an
  arbitrary stlye, if we can bikeshed on this PR then future PRs should be
  able to progress more quickly. I'll take lack of comment on any of the
  above as approval and I'll attempt to be uniform when doing the rest of
  the codebase. I plan on just chipping away at this, I can only do so
  much docs work in a day without getting bored of it :)

  Notes:

  - I didn't touch 'segwit' vs 'SegWit', seems both are widely used.
  - Using ticks inside links may be an overkill but seems more correct?
  - I'm not totally sure where the line is in the Rust ecosystem between
    readability in an editor and rendering as HTML, open to input on this.

Tobin Harding e04795093f Add unit test for bitcoin_merkle_root functions
We test `bitcoin_merkle_root` over in the `blockdata::block` module.
Although the `bitcoin_merkle_root` and `bitcoin_merkle_root_inline`
functions are almost identical there is enough index manipulation done
that it is not immediately obvious that the code is error free.

Add a unit test that verifies that the two functions return the same
resulting merkle root.

using rustdocs.

Also, favour 'creates' over 'constructs' because it is more common in

Merge rust-bitcoin/rust-bitcoin#654: Making globals part of PSBT struct. Closes #652
55c627715f Moving globals into PSBT struct (Dr Maxim Orlovsky)

Pull request description:

  I took the most non-invasive approach to reduce diff size. Many parts of the code can be improved in style or further refactored (like some functions are not necessary and can be just moved to be part of other functions), but I'd prefer to do that as a separate PR once this will be merged.

  My approach with this PR:
  1. Remove `Global` struct by moving its fields right into `PartiallySignedTransaction` - but keep the `util/psbt/map/global.rs` file with all its logic
  2. Keep existing `Map for Global` implementation in the same file, but just change it to `Map for PartiallySignedTransaction`
  3. With serialization, convert `Global` deserialization into crate-private function and use it from `PartiallySignedTransaction` deserialization
  4. Refactor the tests and imports as required to get the thing compile and pass tests

  The refactoring will be followed by PR(s) adding support for Taproot

Tobin Harding 3f5caa501f Clean up module level rustdocs
Docs can always do with a bit of love.

Clean up the module level (`//!`) rustdocs for all public modules.

I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).

Notes:

* Headings - use heading as a regular sentence for all modules e.g.,

```
//! Bitcoin network messages.
```

as opposed to
```
//! # Bitcoin Network Messages
```

It was not clear which style to use so I picked a 'random' mature
project and copied their style.

* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.

* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.

* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.

* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.

Pull request description:

  Adds https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki message signature algorithm

  The base is taken from `bip143::SigHashCache`, some code results duplicated but I think it's more clear to keep things separated

  Would mark some bullet point on https://github.com/rust-bitcoin/rust-bitcoin/issues/503

  Test vectors are taken by running d1e4c56309/test/functional/feature_taproot.py with a modified `TaprootSignatureHash` function to print intermediate values that I cannot found in the bip341 [test vector json](https://raw.githubusercontent.com/bitcoin-core/qa-assets/main/unit_test_data/script_assets_test.json)

  UPDATE: Latest version includes the suggestion from @sanket1729 to create a unified tool for signature message hash for legacy, segwit, and taproot inputs. In particular, makes sense for mixed segwit v0 and taproot v1 inputs because cached values could be shared

This documents cargo features in two ways: explictly in text and in code
using `#[doc(cfg(...))]` attribute where possible. Notably, this is
impossible for `serde` derives. The attribute is contitional and only
activated for docs.rs or explicit local builds.

This change also adds `package.metadata.docs.rs` field to `Cargo.toml`
which instructs docs.rs to build with relevant features and with
`docsrs` config activated enabling `#[doc(cfg(...))] attributes.

I also took the opportunity to fix a few missing spaces in nearby code.

Martin Habovstiak 07774917c2 Use get_or_insert_with in segwit_cache
This refactors the code to make it possible to use `get_or_insert_with`
instead of unwrapping in `segwit_cache()`. To achieve it `common_cache`
is refactored into two functions: one taking only the required borrows
and the original calling the new one. `segwit_cache` then calls the new
function so that borrows are OK.

Apart from removing unwrap, this avoids calling `common_cache` multiple
times.

Martin Habovstiak 497dbfb7c3 Use get_or_insert_with in common_cache()
There was a question whether this is equally performant. There are
multiple good reasons why it should be:

1. `get_or_insert_with` is marked `#[inline]`
2. Any good optimizer will inline a function that is used exactly once
3. 1 and 2 conclude that the closure will get inlined
4. Computing self.tx can then be moved to the only branch where it is
   required.
5. Even if get_or_insert_with didn't get optimized, which is extremely
   unlikely, the `tx` field is at the beginning of the struct and it
   probably has pointer alignment (`Deref` suggests it's a pointer).
   Alignment larger than pointer is not used, so we can expect the
   fields to be ordered as-defined. (This is not guaranteed by Rust but
   there's not good reason to change the order in this case.) We can
   assume that offset to tx is zero in most cases which means no
   computation is actually needed so the expression before closure is
   no-op short of passing it into the closure as an argument.

At the time of writing `#[inline]` can be seen at
https://doc.rust-lang.org/src/core/option.rs.html#933

Instead of using magic numbers we can define constants for the address
prefix bytes. This makes it easier for future readers of the code to see
what these values are if they don't know them and/or see that they are
