Not sure what happened here but our release job didn't catch this? We
should have updated this to "since = 0.31.0" before release. Since we
only deprecate for one release lets go ahead and remove this.
The difficulty is a ratio of the max and current targets, since the
max is network specific the difficulty calculation is also network
specific.
We already have network specific maximum target constants, use them when
calculating the difficulty.
e21ee381bc Split Prevouts errors out into specific error types (Tobin C. Harding)
Pull request description:
Done as part of the great error clean up.
Currently we are returning a general `Error` from `Prevouts` functions, this is un-informative, we can do better by returning specific types that indicate the exact error path.

fde6479c6a Create uniform build script (yancy)
Pull request description:
Previously, each unique compiler cfg attribute that appeared in the codebase was hard coded and emitted to stdout at compile time. This meant keeping the file up to date as different compiler cfg attributes changed. It's inconsequential to emit a compiler version that's not used, so this change just emits all possibilities to reduce the maintenance burden of the build script.
Note that there is a bit of diff noise in one of the `build.rs` since I simply did a copy of one to the other to make them uniform.

Improve the public exports in two ways:
1. Inline re-exports into the docs of the module that re-exports them.
2. Separate public and private use statements
Recently we discussed a way to separate the public and private import
statements to make the code more clear and prevent `rustfmt` joining
them all together.
Separate public exports using a code block and `#[rustfmt::skip]`. Has
the nice advantage of reducing the number of `#[doc(inline)]` attributes
also.
1. Modules first, as they are part of the project's structure.
2. Private imports
3. Public re-exports (using `rustfmt::skip` to prevent merge)
Use the format
```rust
mod xyz;
mod abc;
use ...;
pub use {
...,
};
```
This patch introduces changes to the rendered HTML docs.
Done as part of the great error clean up.
Currently we are returning a general `Error` from `Prevouts` functions,
this is un-informative, we can do better by returning specific types
that indicate the exact error path.
Add two signing examples to showcase signing a simple one input two
output transaction using both segwit v0 outputs and taproot outputs.
This patch is the result of the recent rust-bitcoin TABConf workshop,
wit bug fix by Sanket, updated to use APIs from tip of master branch.
This code, depending on v0.30.0 is what is being introduced to the
cookbook at the moment.
Previously, each unique compiler cfg attribute that appeared in the
codebase was hard coded and emitted to stdout at compile time. This
meant keeping the file up to date as different compiler cfg attributes
changed. It's inconsequential to emit a compiler version that's not

875545517d Add clippy exceptions for needless_question_mark lint (Steven Roose)
Pull request description:
This lint forces you to write semantically different code that is in most cases inferior, just to save you 5 characters.
The reason why the code is inferior is because it doesn't do error conversion so it would break when either of the two function signatures changes while in the original code using the `?` operator, nothing would break if the inner error can be converted into the outer error.

hex_psbt was added as a macro so that a panic would reveal the line
number of the failing test by expanding the macro at the test location.
However, a stack trace can be used to reveal the test that caused the
failure using RUST_BACKTRACE=1. Furthermore, the track_caller macro is
added to the helper methods which will reveal the line number of the
calling function (the offending test). More detailed information for
debugging has been added to hex_psbt() so that the offending string
will be included in the panic message.
The macro psbt_with_values is used by the psbt test module. Since
there is no pre-processing required, there is no reason to use
metaprogramming here, so this commit moves the logic from a
macro to common function in the test module.

- Use `Message::from_digest_slice` instead of `Message::from_slice`.
- Use `secp256k1::Keypair` instead of `secp256k1::KeyPair`.

PR aims to achieve two things:
- Make error code brain dead easy to read
- Get error code closer to being ready for v1.0
The first 8 patches are pretty basic, and are broken up into really small changes. The last patch is much bigger, it has a long git log to explain it but reviewing should not take too much brain power.
This PR does not introduce anything new, it just applies what we have been doing recently with errors. Before v1.0.0 others will likely want to re go over all the error types. As such I believe this PR can be merged under the one ack carve-out.
### TODOs (future PRs)
We have a few errors that still need splitting up:
- Split up `merkle_tree::block::MerkleBlockError`
- Split up `psbt::error::Error`
- Split up `IncompleteBuilderError`
Also, all error From's should probably have `#[inline]`, I noticed late in the process and did not have the heart to visit every error again.

On our way to v1.0.0 we are defining a standard for our error types,
this includes:
- Uses the following derives (unless not possible, usually because of `io::Error`)
`#[derive(Debug, Clone, PartialEq, Eq)]`
- Has `non_exhaustive` unless we really know we can commit to not adding
anything.
Furthermore, we are trying to make the codebase easy to read. Error code
is write-once-read-many (well it should be) so if we make all the error
code super uniform the users can flick to an error and quickly see what
it includes. In an effort to achieve this I have made up a style and
over recent times have change much of the error code to that new style,
this PR audits _all_ error types in the code base and enforces the
style, specifically:
- Is layed out: definition, [impl block], Display impl, error::Error impl, From impls
- `error::Error` impl matches on enum even if it returns `None` for all variants
- Display/Error impls import enum variants locally
- match uses *self and `ref e`
- error::Error variants that return `Some` come first, `None` after
Re: non_exhaustive
To make dev and review easier I have added `non_exhaustive` to _every_
error type. We can then remove it error by error as we see fit. This is
because it takes a bit of thinking to do and review where as this patch
should not take much brain power to review.
In a further effort to make the code brain-dead easy to read; use an
explicit implementation of `std::error::Error` that returns `None`
instead of relying on the default trait implementation.
We would like the codebase to be optimized for readability not ease of
development, as such code that is write-once-read-many should not use
macros.
Currently we use the `impl_std_error` macro to implement
`std::error::Error` for struct error types. This makes the code harder
to read at a glance because one has to think what the macro does.
Remove the `impl_std_error` macro and write the code explicitly.

dac627cc09 Feature: Psbt fee checks (junderw)
Pull request description:
Closes#2061
These new methods on Psbt will add checks for high fees by default. The threshold for "high fees" is currently set to 25000 sat/vbyte, which is about 20x higher than the highest next block fees seen on the "Mempool" website.
The primary goal of this change is to prevent users of the library from accidentally sending absurd amounts of fees.
(ie. Recently in September 2023 there was a transaction that sent an absurd amount of fees and made news in the Bitcoin world. Luckily the mining pool gave it back, but some might not be so lucky.)
There are variants of the method that allow for users to set their own "absurd" threshold using a `FeeRate` value. And there is a method that performs no checks, and the method name is alarming enough to draw attention in a review, so at least developers will be aware of the concept.

- Patch 2 takes a `secp256k1::PublicKey` removing the need for an error path (discussed below).

The `Witness::push_bitcoin_signature` method is old and a bit stale.
Bitcoin has taproot signatures now so the name is stale, also we have
the `crate::ecdsa::Signature` type that holds the secp sig and the hash
type so we can use that instead of having two separate parameters.
Add a new, up to date, `Witness::push_ecdsa_signature` function and
deprecate the `push_bitcoin_signature` one.
There is no logical default for the transaction version number, there is
only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version
they want not rely on us making the choice.
(I originally added this impl to support testing, this was in hindsight
the wrong thing to do, props to Sanket for noticing.)
One of our stated aims is to make it possible to learn bitcoin by using
our library. To help with this aim add to private consts for the segwit
transaction marker and flag serialization fields.
158ba26a8a Feature: Count sigops for Transaction (junderw)
Pull request description:
I copied over the sigop counting logic from Bitcoin Core, but I made a few adjustments.
1. I removed 2 consensus flags that checked for P2SH and SegWit activation. This code assumes both are activated. If we were to include that, what would be a good way to go about it? (ie. If I run this method on a transaction from the 1000th block and it just so happened to have a P2SH-like input, Bitcoin Core wouldn't accidentally count those sigops because the consensus flag will stop them from running the P2SH logic. Same goes for SegWit)
3. Since there's no guarantee that we have an index from which we can get the prevout scripts, I made it into a generic closure that looks up the prevout script for us. If the caller doesn't provide it, We can only count sigops directly in the scriptSig and scriptPubkey (no P2SH or SegWit).
## TODO
- [x] Write tests for transaction sigop counting
~~Edit: The test changes are just to get the 1.48 tests passing. I'll remove them and replace them with whatever solution that is agreed upon in another PR etc.~~
Edit 2: This is the code I used as a guide:
8105bce5b3/src/consensus/tx_verify.cpp (L147-L166)
Edit 3: I found a subtle bug in the implementation of `count_sigops` (https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687)

95b7a95fc2 test: correct psbt used for regression test (Subhradeep Chakraborty)
Pull request description:
The `unknown` key used in the `Psbt` (in `serde_regression_psbt` test) is not really unknown. Also the `preimages` in the `Input` don't seem to be valid. Though they don't affect the tests because of the `serde::serialize`, the `Psbt` itself is invalid and hence this PR.

71a5fe2b54 Customize Debug implementation of absolute::LockTime (Subhradeep Chakraborty)
Pull request description:
Fixes https://github.com/rust-bitcoin/rust-bitcoin/issues/2011.
This PR aims to make the "pretty print" of `absolute::LockTime` prettier by printing `X blocks` and `X seconds` for `Blocks` and `Seconds` respectively instead of the default Enum printing.

BIP-68 activated a fair while ago (circa 2019) and since then only
transaction versions 1 and 2 have been considered standard.
Currently in our `Transaction` struct we use an `i32`, this means users
can construct a non-standard transaction if they do not first look up
what the value should be. We can help folk out here by abstracting over
the version number.
Since the version number only governs standardness elect to make the
inner `i32` public (ie., not an invariant). The aim of the type is to
make life easy not restrict what versions are used.
Add transaction::Version data type that simply provides two consts `ONE`
and `TWO`.
Add a `Default` impl on `Version` that returns `Version::TWO`.
In tests that used version 0, instead use `Version::default` because the
test obviously does not care.

acbf23aaa5 Add `is_multisig` helper to Script type (Clark Moody)
Pull request description:
A new `is_multisig` helper method to classify bare multisig output scripts.
The form of a valid multisig script is:
- Pushnum `M`
- <N> pubkeys
- Pushnum `N`
- `OP_CHECKMULTISIG`
`N` must equal the number of pushed pubkeys, and `M` must be less than or equal to `N`.
I've tested this against the RPC output of Core at the block level, checking that the total number of multisig outputs matches.
```
Block 350338, 89 multisig
Block 350340, 29 multisig
Block 350341, 4 multisig
Block 350343, 579 multisig
Block 350344, 48 multisig
Block 350346, 11 multisig
Block 350347, 404 multisig
Block 350350, 127 multisig
Block 350351, 1 multisig
Block 350353, 40 multisig
Block 350356, 13 multisig
Block 350357, 2 multisig

026a55809e Fix: Script::count_sigops parsing should not return a Result (junderw)
Pull request description:
When implementing some tests for the Transaction PR, I noticed that there were coinbase transactions that would pass Bitcoin Core parsing and fail my code.
It turns out that the Script parsing for sigops calls `break` to exit the loop and returns the current n value whenever there is an EarlyEndOfScript error.
See this comment: https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687 for some links to the relevant source.

These docs do not add that much value, we do not typically bother
documenting `From` and `TryFrom` implementations because they are super
well known and its obvious from the function signature what is going on.
The `address::Error` is module level general, we can make the code
easier to maintain and easier to stabalize by splitting the parse error
out of the general error.
Create a `ParseError` that is returned by `FromStr for Address`. Remove
the now unused variants from the general `address::Error`.
In an effort to reduce the number of lines of code import the error
variants locally within the `Display` impl on `Error`.
Refactor only, no logic changes.
