[rubygems/rubygems] Fix Bundler::Digest#sha1 on big-endian systems

2021-10-25T16:51:05+00:00

As noticed by @nobu https://github.com/rubygems/rubygems/pull/4989#discussion_r735674633

From wikipedia: https://en.wikipedia.org/wiki/SHA-1#SHA-1_pseudocode

> append ml, the original message length in bits, as a 64-bit big-endian integer.

`Q` is native endian, so little-endian on most modern hardware.
The original code from RubyDigest reverses the bytes:
https://github.com/Solistra/ruby-digest/blob/d15f906caf09171f897efc74645c9e31373d7fd1/lib/ruby_digest.rb#L521

But that makes the code non-portable, the correct way is to directly ask
for a big-endian representation.

[rubygems/rubygems] Vendor a pure ruby implementation of SHA1

2021-10-25T11:24:32+00:00

This allows `Source::Git` to no longer load the `digest` gem as it is causing
issues on Ruby 3.1.
