Add a warning to stderr at the end similar to other *sum utilities when --check is used and some files failed verification.
At least the last part of the comment above check_one_checkfile seemed to be incorrect so I removed that comment.
Fixes #283

Changes since 1.3.2:
- Fix incorrect output from AVX-512 intrinsics under GCC 5.4 and 6.1 in
debug mode. This bug was found in unit tests and probably doesn't
affect the public API in practice. See
https://github.com/BLAKE3-team/BLAKE3/issues/271.
|
|
|
|
Changes since 1.3.1:
- Dependency updates only. This includes updating Clap to v4, which
changes the format of the `b3sum --help` output. The new MSRV is
1.59.0 for `blake3` and 1.60.0 for `b3sum`. Note that this project
doesn't have any particular MSRV policy, and we don't consider MSRV
bumps to be breaking changes.
|
|
v6.4.0 has a bug where invalid UTF-16 filenames fail a debug_assert on
Windows. See https://github.com/dylni/os_str_bytes/issues/14. The vast
majority of b3sum users should be running a binary built in release mode
and shouldn't be affected by this. This lockfile change fixes our CI,
but note that `cargo install` doesn't respect lockfiles by default
(without --locked), so anyone running a debug binary against invalid
Windows filepaths (very rare) will still need to wait for an upstream
patch release.

Migrate from the abandoned memmap library to the now maintained fork
of memmap2
|
|
Changes since 1.3.0:
- The unstable `traits-preview` feature now includes an implementation
of `crypto_common::BlockSizeUser`, AKA
`digest::core_api::BlockSizeUser`. This allows `blake3::Hasher` to be
used with `hmac::SimpleHmac`.
|
|
Changes since 1.2.0:
- Added blake3_hasher_reset to the C API, for parity with the Rust API.
- Updated digest to v0.10. This version merged the crypto-mac crate with
digest, so the dependency on crypto-mac has been removed. These trait
implementations are still gated behind the "traits-preview" feature.
- Updated clap to v3.
|
|
|
|
Adjust to the following changes that happened in digest:
- The crypto-mac crate has been merged into digest (with "mac" feature
enabled)
- Various traits have been split up
- The Digest and Mac traits now share their update/finalize/reset
implementations
- The BlockInput trait was dropped without replacement apparently (as
long as the low-level core API is not used)
|
|
We'll need to make sure to update this when we do a version bump. Adding
an explicit `!Cargo.lock` line to b3sum/.gitignore helps with this, by
making sure Cargo.lock shows up by defauls in searches like:
rg "1\.2\.0"
Closes https://github.com/BLAKE3-team/BLAKE3/issues/210.

Changes since 1.1.0:
- SECURITY FIX: Fixed an instance of undefined behavior in the Windows
SSE2 assembly implementations, which affected both the Rust and C
libraries in their default build configurations. See
https://github.com/BLAKE3-team/BLAKE3/issues/206. The cause was a
vector register that wasn't properly saved and restored. This bug has
been present since SSE2 support was initially added in v0.3.7. The
effects of this bug depend on surrounding code and compiler
optimizations; see test_issue_206_windows_sse2 for an example of this
bug causing incorrect hash output. Note that even when surrounding
code is arranged to trigger this bug, the SSE2 implementation is
normally only invoked on CPUs where SSE4.1 (introduced in 2007) isn't
supported. One notable exception, however, is if the Rust library is
built in `no_std` mode, with `default_features = false` or similar. In
that case, runtime CPU feature detection is disabled, and since LLVM
assumes that all x86-64 targets support SSE2, the SSE2 implementation
will be invoked. For that reason, Rust callers who build `blake3` in
`no_std` mode for x86-64 Windows targets are the most likely to
trigger this bug. We found this bug in internal testing, and we aren't
aware of any callers encountering it in practice.
- Added the Hasher::count() method.

Changes since 1.0.0:
- The NEON implementation is now enabled by default on AArch64 targets.
Previously it was disabled without the "neon" Cargo feature in Rust or
the "BLAKE3_USE_NEON=1" preprocessor flag in C. This is still the case
on ARM targets other than AArch64, because of the lack of dynamic CPU
feature detection on ARM. Contributed by @rsdy.
- The previous change leads to some build incompatibilities,
particularly in C. If you build the C implementation for AArch64
targets, you now need to include blake3_neon.c, or else you'll get a
linker error like "undefined reference to `blake3_hash_many_neon'". If
you don't want the NEON implementation, you need to explicitly set
"BLAKE3_USE_NEON=0". On the Rust side, AArch64 targets now require the
C toolchain by default. build.rs includes workarounds for missing or
very old C compilers for x86, but it doesn't currently include such
workarounds for AArch64. If we hear about build breaks related to
this, we can add more workarounds as appropriate.
- C-specific Git tags ("c-0.3.7" etc.) have been removed, and all the
projects in this repo (Rust "blake3", Rust "b3sum", and the C
implementation) will continue to be versioned in lockstep for the
foreseeable future.

Changes since 0.3.8:
- Add Hash::from_hex() and implement FromStr for Hash.
- Implement Display for Hash, equivalent to Hash::to_hex().
- Implement PartialEq<[u8]> for Hash, using constant_time_eq.
- Change derive_key() to return a 32-byte array. As with hash() and
keyed_hash(), callers who want a non-default output length can use
Hasher::finalize_xof().
- Replace Hasher::update_with_join() with Hasher::update_rayon(). The
former was excessively generic, and the Join trait leaked
implementation details. As part of this change, the Join trait is no
longer public.
- Upgraded arrayvec to 0.7.0, which uses const generics. This bumps the
minimum supported Rust compiler version to 1.51.
- Gate the digest and crypto-mac trait implementations behind an
unstable feature, "traits-preview". As part of this change upgrade
crypto-mac to 0.11.0.

Changes since 0.3.6:
- BUGFIX: The C implementation was incorrect on big endian systems for
inputs longer than 1024 bytes. This bug affected all previous versions
of the C implementation. Little endian platforms like x86 were
unaffected. The Rust implementation was also unaffected.
@jakub-zwolakowski and @pascal-cuoq from TrustInSoft reported this
bug: https://github.com/BLAKE3-team/BLAKE3/pull/118
- BUGFIX: The C build on x86-64 was producing binaries with an
executable stack. @tristanheaven reported this bug:
https://github.com/BLAKE3-team/BLAKE3/issues/109
- @mkrupcale added optimized implementations for SSE2. This improves
performance on older x86 processors that don't support SSE4.1.
- The C implementation now exposes the
`blake3_hasher_init_derive_key_raw` function, to make it easier to
implement language bindings. Added by @k0001.

Changes since 0.3.5:
- Fix a build break in the assembly files under older versions of GCC.
|
|
Changes since 0.3.4:
- The `digest` dependency is now v0.9 and the `crypto-mac` dependency is
now v0.8.
- Intel CET is supported in the assembly implementations.
- `b3sum` error output includes filepaths again.

This was previously there, but got dropped in

Changes since 0.3.3:
- `b3sum` now supports the `--check` flag. This is intended to be a
drop-in replacement for e.g. `md5sum --check` from Coreutils. The
behavior is somewhat stricter than Coreutils with respect to invalid
Unicode in filenames. For a complete description of how `--check`
works, see the file `b3sum/what_does_check_do.md`.
- To support the `--check` feature, backslashes and newlines that appear
in filenames are now escaped in the output of `b3sum`. This is done
the same way as in Coreutils.
- To support `--check` interoperability between Unix and Windows,
backslashes in filepaths on Windows are now replaced with forward
slashes in the output of `b3sum`. Note that this is different from
Coreutils.
