We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.
Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.
Commit hash that was tip of `bitcoin_hashes` at time of import:
commit 54c16249e06cc6b7870c7fc07d90f489d82647c7
Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.
NOTE: Does _not_ enable fuzzing for `hashes` in CI.
Notes on CI:
Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.
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.
Move the clippy control to `test.sh` and add an env var `DO_LINT` to
control it. Remove the explicit CI job and run the linter during the
`Test` job using the stable toolchain.
Add a clippy configuration file configuring the MSRV. Add a github
actions job to run clippy on CI.
Please note the job does _not_ use `--all-targets` because doing so
causes:
```
error[E0554]: `#![feature]` may not be used on the stable release channel
--> src/lib.rs:46:54
|
46 | #![cfg_attr(all(test, feature = "unstable"), feature(test))]
```
We currently build the docs as a separate CI job, we can however just do
it as part of the `Tests` job using the nightly toolchain.
Conditionally build the docs based on a `DO_DOCS` env var.
Note, uses `--cfg docsrs` so can only be built run with nightly toolchain.
Disable problematic jobs that involve Github Actions caching or `cross`
whenever the environment is set to ACT. This allows running the CI
pipeline locally and hopefully speeds up PR cycle times by reducing
unexpected CI pipeline results.
Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
