Corrected the implementation of {Digest::CRC5}.
Make digest-crc Ractor-safe.
Silence potential method redefinition warnings when loading the C extensions.
(@ojab)
Broaden rake dependency to >= 12.0.0, < 14.0.0` for ruby 2.7, which includes
rake 13.x.
Lower the rake dependency to ~> 12.0 for ruby 2.6.
Fixed a bug in ext/digest/Rakefile which prevented digest-crc from being
installed on systems where C extensions could not be successfully compiled.
Rake's ruby method, which in turn calls rake's sh method, raises
a RuntimeError exception when the ruby command fails, causing rake to
exit with an error code. Instead, rescue any RuntimeError exceptions and
fail gracefully.
Fix installation issues under bundler by adding rake as an explicit dependency
(@rogerluan).
Implement optional C extensions for all CRC algorithms, resulting in an
average performance improvement of ~40x. Note, if for whatever reason the
C extensions cannot be compiled, they will be skipped and the pure-Ruby
CRC algorithms will be used instead. If the C extensions were successfully
compiled, then they will be loaded and override the pure-Ruby CRC methods with
the C equivalents.
Alias {Digest::CRC16QT} to {Digest::CRC16X25}, since they are effectively the same (@dearblue).
Fix {Digest::CRC32::WIDTH} (@dearblue).
