Tobin C. Harding 5cef2f1a8f Remove stutter for error variants
Error variants should not end with the same identifier as the enum,
i.e., they should not stutter.

Found by clippy after setting:

  avoid-breaking-exported-api = false

Tobin C. Harding 08c4a2204a Allow wrong_self_convention for non-Copy type
Clippy gives a warning about `wrong_self_convention` because we consume
self in a method called `is_*`. We have to consume self because the
object has a generic `E` (error type) that does not implement `Copy`.
2022-08-02 08:54:54 +10:00
Tobin C. Harding 0786d92a5c Take self by value
Turns out by default clippy does not lint certain parts of the public
API. Specifically, by setting

  avoid-breaking-exported-api = false

we can get clippy to lint the public API for various things including
`wrong_self_convention`.

Clippy emits:

 warning: methods with the following characteristics: (`to_*` and `self`
 type is `Copy`) usually take `self` by value

As suggested, take `self` by value for methods named `to_*`.

sanket1729 0b88051318 Update TaprootBuilder::finalize
This commit does two things:
1) BUG FIX: We should have checked that the length of the branch is 1
before computing the spend_info on it. This was introduced in #936, but
slipped past my review :(
2) Update the return type to return the consumed `self` value. This
function can only error when there the tree building is not complete.
Returning TaprootBuilderError causes issues in downstream projects that
need to deal with error cases which cannot happen in this function

Merge rust-bitcoin/rust-bitcoin#1137: Impl string conversion traits for `CommandString`
405be52f5c Impl string conversion traits for `CommandString` (Martin Habovstiak)

Pull request description:

  After MSRV bump `try_from` usually refers to `TryFrom` method but
  `CommandString` used inherent one making it confusing and non-idiomatic.

  This implements `FromStr` and `TryFrom<{stringly type}>` for
  `CommandString` and deprecates the inherent method in favor of those.
  To keep the code using `&'static str` efficient it provides
  `try_from_static` inherent method that only converts from
  `&'static str`.

Pull request description:

  The BIP-158 finalize code was serializing value to `Vec` only to

Tobin C. Harding 34f955a073 Introduce new canonical license blurb
Recently we introduced SPDX license ids but there was some confusion
about the use, form, and purpose of lines before (library name, author).

It was pointed out to me by Andrew that if/when folks cut'n'paste our
code they often will keep the whole blurb. Design it with that in
mind. FTR, Andrew also indicated that he did not mind his name being
removed in favour of "The rust-bitcoin developers".

At first I thought the term "The rust-bitcoin developers" was a bit
wishy-washy but yesterday I realised that I am proud to be part of that
crew, striving to deliver code to the highest possible standard.

Introduce a canonical format for the licences blurb.

- Use the name of the library
- Use "The rust-bitcoin developers"
- Use the SPDX ID

Martin Habovstiak 071a1c02b7 Implement string parsing for `Sequence`
`Sequence` didn't have `FromStr` nor `TryFrom<{stringly type}>`
implemented by accident. This moves a macro for implementing them from
`locktime` module to the `parse` module, renames it for clarity and uses
it to implement parsing for `Sequence`.

Martin Habovstiak c39bc3909d Extend `ParseIntError` to carry more context
When debugging parsing errors it's very useful to know some context:
what the input was and what integer type was parsed. `ParseIntError`
from `core` doesn't contain this information.

In this commit a custom `ParseIntError` type is crated that carries the
one from `core` as well as additional information. Its `Display`
implementation displays this additional information as a well-formed
English sentence to aid users with understanding the problem. A helper
function parses any integer type from common string types returning the
new `ParseIntError` type on error.

To clean up the error code a bit some new macros are added and used.
New modules are added to organize the types, functions and macros.

Closes #1113

Tobin C. Harding 0ed78e543b Add lock time types
Add a `LockTime` type to hold the nLockTime `u32` value. Use it in
`Transaction` for `lock_time` instead of a `u32`. Make it public so this
new type can be used by rust-miniscript and other downstream projects.

Add a `PackedLockTime` type that wraps a raw `u32` and derives `Ord`,
this type is for wrapping a consensus lock time value for nesting in
types that would like to derive `Ord`.

Tobin C. Harding 1390ee12ec Add a max scriptnum constant
Integers within Script can have a maximum value of 2^31 (i.e., they are
signed) but we (miniscript) often uses unsigned ints, to facilitate
checking the unsigned type is the correct size to fit in a signed int
add a const `MAX_SCRIPTNUM_VALUE`.

Pull request description:

  Currently we run clippy in CI using a github action. The invocation has a couple of shortcomings

  1. it does not lint the tests (this requires `--all-targets`)
  2. it does not lint the examples

  I could not find a way to lint the examples without explicitly linting each example by name.

  **This PR does the following:**

  - Fix clippy issues (patch 1-4)
  - Move the clippy control to `test.sh`
  - Add an env var `DO_LINT` to control it
  - Remove the separate CI job
  - Run the linter during the `Test` job using the stable toolchain.
  - Run clippy with ` --all-features` AND `--all-targets` (only recently made possible).
  - Run each example explicitly

  Thanks to dunxen for noticing all the errors in my psbt example on review and prompting me to work out why clippy was not running :)

Pull request description:

  > Adds the basic structures for BIP152 and a method to create a compact block from a full block.

  This is a rebase of #249 by stevenroose (see https://github.com/rust-bitcoin/rust-bitcoin/pull/249#issuecomment-1170562141) with a milestone for 29.0. I've added deserialization and serialization tests for the network messages and fixed an off-by-one bug in the deserialization of the differentially encoded varints in the `getblocktxn` message (see https://github.com/rust-bitcoin/rust-bitcoin/pull/249#discussion_r914989521).

  Closes #249.

Pull request description:

  Leading double colons are a relic of edition 2015. Attempt to remove _all_ leading double colons (assuming I didn't miss any).

  - Patch 1 is done mechanically so it can be repeated by reviewers, just search-and-replace ' ::' with '::' (note the leading space).
  - Patch 2 does a single other instance of leading `::`

Pull request description:

  This is dr-orlovsky's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/899) picked up at his permission in the discussion thread.

  I went through the review comments and implemented everything except the perf optimisations. Also includes a patch at the front of the PR that adds a unit test that can be run to see the "before and after", not sure if we want it in, perhaps it should be removed before merge.

  This PR implicitly fixes 942.

  To test this PR works as advertised run `cargo test display_transaction --features=serde -- --nocapture` after creating a unit test as follows:
  ```rust

      // Used to verify that parts of a transaction pretty print.
      // `cargo test display_transaction --features=serde -- --nocapture`
      #[cfg(feature = "serde")]

      fn serde_display_transaction() {
          let tx_bytes = Vec::from_hex(

  This solution is a little more straightforward. The name and documentation should be enough to prevent misuse.

Pull request description:

  When `rust-bitcoin` was started in 2014 the SPDX license list and short identifiers where not a thing. Now that we have short identifiers and they are gaining popularity in other projects we can consider using them.

  - Add links to the SPDX website in the readme
  - Shorten the author section to a single line
  - Remove all the licence information in each file and replace it with an
  SPDX ID (see https://spdx.dev/ids/#how)

  Of note:

  - If the author of a file is explicitly listed, maintain this information
  - If the 'author' is listed as the generic 'Rust Bitcoin developers' just remove the attribution, this is implicit. This does loose the date info but that can be seen at any time from the git index using

    `git log --follow --format=%ad --date default <FILE> | tail -1`

  apoelstra, please confirm that I'm not treading on your toes here, especially, are you ok with the new 'written by' string format?

Pull request description:

  Currently we are using the fragment-specifier `expr` in a bunch of

  instead it allows the compiler to give slightly more specific error
  messages.

  The benefits of this change are minor. Of note, this patch found one
  unusual macro call site (removed unnecessary `&`).

  The macros changed are all internal macros, this is not a breaking change.

  Last release, before we had access to `non_exhaustive` we added some fancy types to enable conditionally having a `bitcoinconsensus::Error`.

  Now that we have bumped the MSRV and have already added `non_exhaustive` to the `Error` type in question, we can use a compiler attribute to conditionally include the `bitcoinconsensus` error.

  Remove `Uninhabited` and its usage.

  For more context see the [original attempt ](https://github.com/rust-bitcoin/rust-bitcoin/pull/1025)at using `Infallible` (last comment in discussion thread).

Optimize Witness Serialization
We allocated a new vector when serializing a `Witness`. That was
inefficient and unnecessary. Use `serialize_seq` to feed the witness
elements directly into the serializer.

Optimize `Witness` serialization by removing the allocation.

Tobin C. Harding 91ff2f628c Introduce SPDX license identifiers
When `rust-bitcoin` was started in 2014 the SPDX license list and short
identifiers where not a thing. Now that we have short identifiers and
they are gaining popularity in other projects we can consider using
them.

- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)

Of note:

- If the author of a file is explicitly listed, maintain this
information
- If the 'author' is listed as the generic 'Rust Bitcoin developers'
just remove the attribution, this is implicit. This does loose the date
info but that can be seen at any time from the git index using

  `git log --follow --format=%ad --date default <FILE> | tail -1`

Tobin C. Harding bea5569cd3 Remove duplicate must_use
Clippy emits:

 warning: this function has an empty `#[must_use]` attribute, but
 returns a type already marked as `#[must_use]`

This is because the return type of the function
`legacy_encode_signing_data_to` is `EncodeSigningDataResult` which is
already marked as `must_use`. There is no need to have `must_use` on the
function also.

I'm guessing this got through to master because we only just added
clippy to CI.
