66d5800ac0 psbt: Add IndexOutOfBounds error (Tobin C. Harding)
Pull request description:
We currently have a bunch of functions that are infallible if the `index` argument is within-bounds however we return a `SignError`, this obfuscates the code.
Add an `IndexOutOfBoundsError`. While we are at it make it an enum so users can differentiate between which vector the out of bounds access was attempted against.

Pull request description:
During the 0.30.0 release we removed the re-exports of hash types. This upset some folk and since the aim of our re-exports is not exactly clean as well as the fact that the public API surface is not yet fixed just re-export all the hash types at the crate root again.

We currently have a bunch of functions that are infallible if the
`index` argument is within-bounds however we return a `SignError`, this
obfuscates the code.
Add an `IndexOutOfBoundsErorr`. While we are at it make it an enum so
users can differentiate between which vector the out of bounds access
was attempted against.
Throughout the codebase we cast values to `u64` when constructing a
`VarInt`. We can make the code marginally cleaner by adding `From<T>`
impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single
place.
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.
Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.
This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.
BIP-32 defines 4 4-byte consts used as version bytes; currently we are
hardcoding the version bytes in multiple places.
Add BIP-32 version bytes consts and use them throughout the module.
The BIP-32 extended public key and extended private key exist in the
Bitcoin vernacular as xpub and xpriv. We can use these terms with no
loss of clarity.
Rename our current BIP-32 types
- `ExtendedPubKey` to `Xpub`
- `ExtendedPrivKey` to `Xpriv`

Currently if the witness has zero elements or any of the individual
witnesses is empty we panic. Panic is caused by subtracting 1 from a
zero length.
Check the length is non-zero before subtracting 1, print `[]` if empty.

Currently the `bitcoinconsensus` error is part of the public API. This
hinders maintainability because changes to the verison of
`bitcoinconsensus` force a re-release in `rust-bitcoin`. This is
an unnecessary maintenance burden, we can wrap the error instead.

f3412325ea weight: Make docs uniform and terse (Tobin C. Harding)
Pull request description:
- Patch 1 is docs cleanup
- Patch 2 adds two functions to `FeeRate`
From the commit log of patch 2:
Calculating the absolute fee from a fee rate can currently be achieved
by creating a `Weight` object and using
`FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
can add two public convenience functions that make discovery of the
functionality easier.
Add two functions for calculating the absolute fee by multiplying by
weight units (`Weight`) and virtual bytes (by first converting to weight
units).
This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

Pull request description:
EDIT: The commit hashes below are stale but the text is valid still.
In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.
The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.
Its all pretty trivial except:
- commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
- comimt `5a196535 Add InvalidSighashTypeError`
- commit `05772ade Use defensive documentation`
Particularly the last one might be incorrect/controversial.
Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.

Improve the script hash types by doing:
- Define the types in the `crypto::script` module
- Put the From impls directly below the type definitions
Keep the current crate level re-export so this does not impact the
public API _if_ people are using the re-export but is still a breaking
change.

- Define the types in the `crypto::key` module

The `ServiceFlags` type is used by the p2p layer. It can live in the
`mod.rs` file of the `p2p` module. Done in preparation for removing the
`p2p::constants` module.
This is a straight code move, the `ServiceFlags` replaces the
current re-export.
The `PROTOCOL_VERSION` const is a p2p layer constant. It can live in the
`mod.rs` file of the `p2p` module.
This is a straight code move, the `PROTOCOL_VERSION` replaces the

The `network` module deals with data types and logic related to
internetworking bitcoind nodes, this is commonly referred to as the p2p
layer.
Rename the `network` module to `p2p` and fix all the paths.
Only commit in the docs and error messages to what we _really_ know.
In an attempt to reduce the likelyhood of the code going stale only
commit to what is guaranteed - that we have an error from a module.
This does arguably reduce the amount of context around the error.
As we do for `NonStandardSighashErrorType` add an error struct for
invalid sighash type, used by the `taproot` module instead of returning
a generic error enum with loads of unused variants.
Error types conventionally include `Error` as a suffix.
Rename `NonStandardSighashType` to `NonStandardSighashTypeError`.
While we are at it make the inner type private to the crate, there is no
need to leak the inner values type.

This type was defined in the `transaction` module because it was
originally used in a function that had been deprecated in favour of
moving the logic to the `sighash` module.
We just removed the deprecated code so we can now move this type to the
`sighash` module where it is used.
We only keep deprecated code around for one release so we can now remove
code deprecated in v0.30.0
Done in preparation as we gear up for v0.31.0 release.
RawNetworkMessage keep the payload_len and its checksum in the struct, thus
is not needed to serialize the inner network message
pub in fields of both RawNetworkMessage and CheckedData are removed so that
invariant are preserved.

9787ba6c96 Rename Script::empty to Script::new (Tobin C. Harding)
Pull request description:
The `empty` constructor is mis-named for the following reasons:
- Non-uniform with `ScriptBuf::new`
- Non-standard with respect to stdlib which uses `Path::new` and `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)
Rename the function to `new`, put it at the top of the impl block while we are at it.

Pull all the code that depends on `bitcoinconsensus` out into a separate
module `consensus::validation`.
Leave transaction testing of bitcoinconsensus code in the transaction
module.
There is not need to return the general `script::Error` from the
transaction verify functions. We can better describe the error path by
returning a custom error.
There is no need no nest the `bitcoinconsensus::Error` type within the
`script::Error`, it is the only error type returned by the verify
functions so just return it directly.

The previous code seems to have been rebased/iterated on too many times,
and had room for significant simplification. By inlining the indentation
logic we can eliminate 40 LOC and also clean up the output by removing
trailing spaces.

Currently the test `hex` macro is only available when the `test`
compiler configuration option is set but we are using it in benches
code, this works for use because `cargo bench` sets `test` for the
current crate, however it breaks downstream crates.

Add rustdocs to `WitnessProgram` commenting on why we carry the witness
version number around with the witness program. This is mainly a dev
comment but it helps document the invariants so make it a rustdoc
comment.
From BIP 141:
> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that
> consists of a 1-byte push opcode (for 0 to 16) followed by a data push
> between 2 and 40 bytes gets a new special meaning. The value of the
> first push is called the "version byte". The following byte vector
> pushed is called the "witness program".
`WitnessVersion` and `WitnessProgram` are scriptPubkey concerns and
scriptPubkey is basically synonymous with address so in one way it makes
sense that these types are in `address` however we are in the process of
overhauling the `Address` (and `AddressInner`) types so lets move the
witness stuff to `script` and put it in individual sub-modules.
This move helps simplify the address error type also.
Note please, there are a bunch of formatting changes in here in the
error type that I cannot explain and could not remove.

Planning to also add methods for the various parts of Transaction etc. to eventually allow for easier sigops calculation.
Bare multisig is making a comeback, which is causing a large amount of transactions' effective vSizes (for fee calculation) to be dependent on the sigop count.

The `as_script_map` is a getter not a conversion function (to/into/as),
as such it should not include the prefix `as_`.
Deprecate `as_script_map` in favour of `script_map`.
This error type is only used in the `from_slice` function. Use prefix
`Sig` because `taproot::FromSliceError` does not fully express how the
error came about.
Use specific identifier for the error, this aids usage but also prevents
us later adding "random" other variants into this error and using it in
other functions.

We have methods to convert a script to a `WScritpHash` and `ScriptHash`,
no need to do this manually, let alone use the `psbt::Serialize` trait
to do so.
These constants had an error that they had `script_size` set to 0 which
was incorrect because it's not length of the script but serialized size.
Rather than just bumping the value this uses the `from_slice` method
which is less error-prone.
This also deletes a useless test of the constants.

8e6f953aa7 Expose valid (min, max) difficulty transition thresholds (Wilmer Paulino)
Pull request description:
Once `U256` was made private, we lost the ability to check whether a valid difficulty transition was made in the chain, since `Target` doesn't expose any operations. We only choose to expose `Shl<u32>` and `Shr<u32>` such that we can compute the min and max target thresholds allowed for a difficulty transition.
This is something we realized was missing after bumping to `rust-bitcoin v0.30.0` in `rust-lightning`, specifically for our `lightning-block-sync` crate. It may also be worth having a helper in `rust-bitcoin` that checks a header properly builds upon the previous, but that can be left for future work.

Pull request description:
I've been reading over the `predict_weight` function since it is one of the biggest challenges for coin-selection. IE choosing inputs and constructing an optimal selection strategy requires predicting the weight to get the best selection.

1) why are we looking at the size of VarInt struct here
> let script_size = script_len + VarInt(script_len as u64).len()
2) [predict_weight_internal](36500b4451/bitcoin/src/blockdata/transaction.rs (L1245)) has a bunch of magic numbers. I'd like to be able to comment this as well but I don't fully understand that function.

Once `U256` was made private, we lost the ability to check whether a
valid difficulty transition was made in the chain, since `Target`
no longer exposes any arithmetic operations.
Our previous MSRV did not support MIN/MAX associated consts so we had
methods min/max_value. Now that our MSRV is Rust 1.48.0 we can use the
consts.
Deprecate min/max_value methods in favor of MIN/MAX associated conts.
We currently use the functions `min_value` and `max_value` because the
consts were not available in Rust 1.41.1, however we recently bumped the
MSRV so we can use the consts now.

984fe69448 bitcoin: Remove attribution from all files (Tobin C. Harding)
Pull request description:
Please note, whether or not we need a per-file license comment is out of scope for this PR. This PR leaves us with the most simple per-file solution possible and leaves the merit of per-file license comment to be discussed on another day.
Simplify the per-file license stuff by doing:
- Remove the attribution line from each file.
Currently we have a mishmash of attribution lines accompanying the SPDX identifier. These lines are basically meaningless because:
- The date is often wrong
- The original author attributed is not the only contributor to a file
- The term "rust bitcoin developers" is basically just noise
- Introduce SPDX license identifiers into `hashes` and remove attribution line (ie, make `hashes` uniform with `bitcoin`)
Required before merge please:
- [x] ack from apoelstra because as the library original author many of the changes in this PR remove his name
- [x] ack from Kixunil because he had some concerns in the issue descussion
Fix: #1816

Just remove all the attribution lines and be done with it. While we are
at it add an SPDX line to the few files missing it, whether this license
nonsense is even needed is left as an argument for another day.

29cb34eed7 Refactor Address struct and its methods (Harshil Jani)
Pull request description:
Closes#1755
In this PR the `as_unchecked` is added to the Address struct, which returns a reference to the same address but with the type Address<NetworkUnchecked>. Similarly, the `assume_checked_ref` is added to Address<NetworkUnchecked>, which returns a reference to the same address but with the type Address.

91f45a214f Replace hardcoded values with compile-time hashing (Martin Habovstiak)
095b7958dd Make `sha256t_hash_newtype!` evocative of the output. (Martin Habovstiak)
Pull request description:
The Rust API guidelines state that macros should be evocative of the
output, which is a sensible recommendation. We already had this for
`hash_newtype!` macro but didn't for sha256t version.
This changes the macro to have this syntax:
```rust
sha256t_hash_newtype! {
// Order of these structs is fixed.
/// Optional documentation details here. Summary is auto-generated.
/*pub*/ struct Tag = raw(MIDSTATE_BYTES, LEN);
/// Documentation here
#[hash_newtype(forward)] // optional, default is backward
/*pub*/ struct HashType(/* attributes allowed here */ _);
}
```
Closes https://github.com/rust-bitcoin/rust-bitcoin/issues/1427
Depends on #1769
How do you like the syntax? Is weird `struct Foo = bar(..);` acceptable?

This commit refactors the Address struct and its methods to improve
its functionality and usability.The AddressInner struct now holds
the payload and network, and the PhantomData<V> type is used to track
the network validation state.
Also as_unchecked and assume_checked_red methods are added to allow
conversion between checked and unchecked network validation state.
