6e56feed57 bip158: Replace usage of HashSet with BTreeSet (Tobin C. Harding)
Pull request description:
The `bip158` module uses a `HashSet` and in order to do so requires the `hashbrown` dependency for "no-std" builds.
We can replace the usage of `HashSet` with a `BTreeSet` in `bip158` and remove the `hashbrown` dependency entirely.
This patch makes no claims about performance cost or benefit of this change. The patch also makes no claims about the validity of the current `HashSet` usage.
The `hashbrown` dependency and `HashSet` usage can be trivially added back in if someone comes up with perf data to back it up.

We can make the API more ergonomic by taking a generic argument that
implements `Into<secp256k1::PublicKey>` in the `bitcoin::PublicKey`
constructors.
The only thing than this is useful for is passing in `KeyPair` and the
`From` implementation already exists. Add a unit test to verify.
Fix: #1453
Currently we have an attempted tag ```compile_fail that seems to be
aiming at allowing code that does not build to exist in rustdoc. This is
causing an error when running tests.
No clue how this made it through CI.
Use ```ignore to prevent rustdoc code from being built.
Currently the derived implementation of `Debug` for `ScriptBuf` prints
the inner vector of u8s as integers, this is ugly and hard to read. The
`Script` implementation of `Debug` prints the script opcodes and data as
hex, we can just delegate to it.
With this applied we get debug output of form:
Script(OP_DUP OP_HASH160 OP_PUSHBYTES_20 \

The term "final" is an archaic Bitcoin term however it is well used, it
exists in Bitcoin Core code as well as in various bips. To help folks
new to Bitcoin add documentation to the `is_final` method including
historical notes.
The `bip158` module uses a `HashSet` and in order to do so requires the
`hashbrown` dependency for "no-std" builds.
We can replace the usage of `HashSet` with a `BTreeSet` in `bip158` and
remove the `hashbrown` dependency entirely.
This patch makes no claims about performance cost or benefit of this
change. The patch also makes no claims about the validity of the current
`HashSet` usage.
The `hashbrown` dependency and `HashSet` usage can be trivially added
back in if someone comes up with perf data to back it up.
Previously `Debug` was implemented for both `Address<NetworkChecked>`
and `Address<NetworkUnchecked>`, but not for cases when the
`NetworkValidation` parameter was generic. This change adds this
ability.
In preparation for deprecating the `is_final` method; move the
`enables_absolute_lock_time` method to be directly above the `is_final`
method.
Refactor only, no logic changes.
The `HexWriter` is not used any more since we added the new hex code in
internals for fast hex encoding.
While we are removing the benches for `HexWriter` also remove the last
remaining bench for writing using `Display` because this is not the
correct place for that code - its trivial to re add later in the correct
module.
`Sighash` does not need to implement `Encodable` because it is
claimed (I don't know exactly myself) that `Sighash` is never consensus
encode in Bitcoin.
We are currently relying on `Sighash` to implement `Encodable` when
encoding creating the segwit v0 sighash for a single input.
For reference, from BIP143:
If sighash type is SINGLE and the input index is smaller than the
number of outputs, hashOutputs is the double SHA256 of the output
amount with scriptPubKey of the same index as the input;
We can use `write_all` directly to write the hashed bytes and remove the
implementation of `Encodable` from the `Sighash` type.
While we are at it, use `write_all` to write the zero hash also to make
the code more uniform and understandable.

53ee42d7c1 Fix ASAN in CI (Tobin C. Harding)
Pull request description:
When we merged `hashes` into `rust-bitcoin` we ran the test script a couple of times using `./hashes/contrib/test.sh` this causes the `cargo` commands in the CI script to be run from the crate root which is not what we want.
This showed up recently because `cargo test` was getting run in `bitcoin` after building with address/memory sanitazation configured into the build.
While we are at it run `cargo clean` after the last sanitizer build just to future proof the CI script in case we later accidentally re-use the same build with plain old `cargo` (without `-Zbuild-std etc.`).

Currently the docs build commands in `hashes` and `bitcoin` differ, they
should be the same.
Add a command `cargo doc` to improve coverage e.g., recently we botched
the feature guarding but since CI only runs `cargo rustdoc` with custom
compiler conditional set we didn't catch it.
Run docs in CI using nightly and stable toolchains as required.

Pull request description:
Add more mutation testing to the `pow` module.
The first two patches are preparatory clean up.
All functions/methods that are non-trivial are tested excluding:
- `to_compact_lossy`
- `from_compact`
- `fmt_decimal`
I think its ok to not test `fmt_decimal`. The compact format ones require a bit of work to do but should be done at some stage.

Recently we introduced some mutation testing to the `pow` module but
testing is never done - add more `mutate` attributes and add unit tests
to ensure all mutants are killed.
Of note, the `from_compact` and `to_compact_lossy` functions are not
done, doing so results in a bunch of surviving mutants.
bef7c6e687 Use marker type to enforce validation of `Address`'s network (Jiri Jakes)
Pull request description:
Adds marker type `NetworkValidation` to `Address` to help compiler enforce network validation. Inspired by Martin's suggestion. Closes#1460.
Open questions:
1. Compilation fails with serde, which uses `Address:from_str` via macro `serde_string_impl!(Address, "a Bitcoin address");`. I don't think there is much we can do, so unless somebody has a better idea how to combine serde and network validation, I would just demacroed the macro for `Address` and add `unsafe_mark_network_valid` into it.
2. Would someone prefer wrapping the validation types by `mod validation`? As they are now, they live in `address` namespace so I don't think mod is necessary.
3. Almost all methods that used to be on `Address` are now on `Address<NetworkValid>` except one (`address_type`) that needs to be called on both and a few that are only on `Address<NetworkUnchecked>` (mainly `is_valid_for_network`). Some methods (e. g. `to_qr_uri`, `is_standard` and perhaps others) could be, theoretically, called on both valid and unchecked. I think we should encourage validating the network ASAP, so I would leave them on NetworkValid only, but I can move them if others have different opinion.
4. Should `NetworkValid` and `NetworkUnchecked` enums have some trait impls derived? The `PartialEq` was necessary for tests (I think `assert_eq` required it) but I am not sure whether some other would be good to have. The enums are only used as types so I guess it's not necessary, but also I do not fully understand why the `PartialEq` was needed.

Parsing addresses from strings required a subsequent validation of
network of the parsed address. However, this validation was not
enforced by compiler, one had to remember to perform it.
This change adds a marker type to `Address` that will assist the
compiler in enforcing this validation.
f39cd88f5f Use TapNodeHash in NodeInfo (sanket1729)
5ff2635585 Rename TapBranchHash -> TapNodeHash (sanket1729)
Pull request description:
This does not completely fix#1393 but is a simple starter. Unfortunately, we still need hash_new_type for `TapNodeHash` because is exported as the Merkle root in taproot psbt. This requires serialization and display/from_str methods.
This also adds a method 1) `TapNodeHash::from_script` to deal with single leaf case cleanly. As a nice side effect, this removes the ugly uses of `sha256::Hash` that I had used to represent both `TapLeafHash` and `TapBranchHash`
Does not fix
1) Exporting `TapTweakHash`. This requires some changes to macros we use.
2) Safer usage of `TapNodeHash` by not making it `hash_new_type` and having guarded constructors. As mentioned above, this is required for psbts and sharing Merkle roots. Perhaps, we might need a new type while constructing trees that is not `hash_new_type`, and convert it to another type that represents the final Merkle root.
My overall feeling is that this is best addressed with more examples than changing and complicating existing code.
I don't feel strongly about the rename, so can go back if `TapBranchHash` instead of `TapNodeHash`.
