- Improve error handling of file flags and xattrs. You now get warnings
- file flags on *BSD/Darwin use a mask and combine with the user/superuser
mask to prevent spurious warnings. The mask is not yet implemented as
a preference
- error handling/report for reading special files
- bump to go 1.20 for errors.Join
The exclude by attribute function is broken on non-Darwin POSIX: linux and freebsd.
This is because those xattrs must be prefixed by a legal namespace. The old xattr
library implicitly appended the user namespace to the xattr, but the current
official go pkg does not (which is just as well).
Also fix the test to remove the discordant old xattr dependency and provide
test cases for both darwin and non-darwin POSIX.
Zstd compression can be enabled by providing `-zstd` or `-zstd-level <level>`
to `init`, `add`, or `backup`. With `-zstd` the compression level will be
`default`, and with `-zstd-level` the level can be any of `fastest`, `default`,
`better`, or `best`.
highwayhash 1.0.1 contains a bug leading to incorrect hashes on arm64 machines.
The 1.0.1 version is retained in github.com/gilbertchen/highwayhash so the hash
can be checked again if a mismatch is detected by 1.0.2.
