Implementing this for spendinfo is really complicated because it
contains some cached data without retaining the components that are used
to compute them.
Users should serde the 1) NodeInfo and 2) internal key and reconstruct
TaprootSpendInfo from it.
Cleanly separate `TapTree` and `NodeInfo`. Fix serde not respecting
invariants for several data structures
Repurpose some tests from removed taproot builder for taptree
We created the `crypto` crate as a container for cryptography modules
with the idea that it may be split out into a separate crate. There is
no reason for users of the lib to know about this module. Also, we have
two `taproot` modules, one in `crypto` and one at the crate root, this
makes for un-ergonomic usage of the lib.
Improve the public API by doing:
- Make the `crypto` module private (`pub(crate)`).
- Re-export `crypto::taproot::Signature` (and `Error`) from
`crate::taproot`
"schnorr" is a dirty word; the current `schnorr` module defines a
`Signature` that includes a sighash type, this sighash type is a bitcoin
specific construct related to taproot. Therefore the `Signature` is
better named `taproot::Signature`. Note also that the usage of `schnorr`
in `secp256k1` is probably justified because the
`secp256::schnorr::Signature` is just doing the crypto.
While we are at it, update docs and error messages to use "taproot"
instead of "schnorr". Also change function names and identifiers that
use "schnorr".
The `TaprootMerkleBranch` and `ControlBlock` both have methods on them
called `from_slice` but these methods do more that just basic copy from
a slice. `decode` is a more descriptive name.
Deprecate the `from_slice` methods and implement `decode`, on other
changes to the logic.
Remove `FromHex` from hash and script types
- Remove the `FromHex` implementation from hash types and `ScriptBuf`
- Remove the `FromStr` implementation from `ScriptBuf` because it does not
roundtrip with `Display`.
- Implement a method `from_hex` on `ScriptBuf`.
- Implement `FromStr` on hash types using a fixed size array.
This leaves `FromHex` implementations only on `Vec` and fixed size arrays.
This renames `Script` to `ScriptBuf` and adds unsized `Script` modeled
after `PathBuf`/`Path`. The change cleans up the API a bit, especially
all functions that previously accepted `&Script` now accept truly
borrowed version. Some functions that perviously accepted `&[u8]` can
now accept `&Script` because constructing it is no loger costly.
This can be replicated by deleting the `type PackedLockTime = LockTime'
line, and then running
find . -type f | xargs sed -i 's/PackedLockTime/LockTime/g
at the root of the repo.
My local scripts did not test serde feature on merge commit. While
merging 734, I accidently broke the serde feature on latest master. This
PR fixes it.
962abcc963 Add serde regression tests (Tobin Harding)
Pull request description:
Attempts to add regression tests for _all_ types defined in `rust-bitcoin` that implement `Serialize`/`Deserialize`.
- Add a `tests` directory and implement regression tests in there
- Use files for input hex and output bincode to reduce source file clutter
- Copy test block and `include_bytes!` usage from RCasatta's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/750)
- Uses Kixunil's macro suggested below
- Adds a single regression test to `util/taproot.rs` for private types
## Note to reviewers
- Uses JSON for opcodes in a separate file (`tests/regression_opcodes.rs`), for all other tests uses bincode.
- Bypasses the order issue for maps by only serializing maps with a single element - is this correct?
Fixes#723

This transaction broke past versions of `rust-bitcoin` and LND so this
adds a test to avoid reintroducing the problem in the future.

In order that we can safely change/maintain de/serialization code we
need to have regression tests with hard coded serializations for each
type that implements serde.
It is enough to test a single serde data format, use JSON for `opcodes`
and bincode for other types.
Do regression testing in a newly added `tests` module.
