Release 0.6.37 of the digest package arrived at CRAN today and has also been uploaded to Debian.
digest
creates hash digests of arbitrary R objects. It can use a number
different hashing algorithms (md5, sha-1,
sha-256, sha-512, crc32,
xxhash32, xxhash64, murmur32,
spookyhash, blake3,crc32c,
xxh3_64 and xxh3_128), and enables easy
comparison of (potentially large and nested) R language objects as it
relies on the native serialization in R. It is a mature and widely-used
package (with 70.8 million downloads just on the partial cloud mirrors
of CRAN which keep logs) as many tasks may involve caching of
objects for which it provides convenient general-purpose hash key
generation to quickly identify the various objects.
This release updates one of the different hashing source functions
which, to remain close to their upstream, used Free() and
Calloc() (uppercased to use the R allocator) but not the
prefixed stricter versions R_Free() and
R_Calloc(). R will switch to enforcing these in the next
release next year. Kevin had
noticed (while doing some other testing) that this now fails under
R-devel (with a switch set), and prepares a very nice and clean PR to
take care of it. As of today, CRAN is now sending ‘please fix,
or else …’ notes so it was a good time to send this to CRAN. We also updated some
remaining http URLs in the README.md to https, and switched to
Author/Maintainer field to the now also mandatory Authors@R.
