Bundle bigdecimal and base64

[DannyBen]

Ruby 3.3 started issuing warnings about using base64 and bigdecimal without having them in the bundle of the gems.

Reproduction

# test.rb
require 'bundler/inline'

gemfile do
  source "https://rubygems.org"
  gem "multi_xml"
end

puts "DONE"

Output

$ ruby -v
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-linux]

$ ruby test.rb
/home/vagrant/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/multi_xml-0.6.0/lib/multi_xml.rb:1: warning: base64 was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add base64 to your Gemfile or gemspec. Also contact author of multi_xml-0.6.0 to add base64 into its gemspec.

For me, the bigger issue is that this warning cascades down, so currently all my gems that use HTTParty (which uses multi_xml) are showing this problem and require me to add runtime dependencies that are not mine to bundle.

Left a similar comment in HTTParty just now in an open issue about it

Other gems have resolved adding the gems to the gemspec, in this case base64 and bigdecimal.

here an example: https://github.com/thinreports/thinreports-generator/pull/134/files

Yes, as have I - but this is a stopgap measure. You should not need to bundle someone else's dependencies.

Fixed in #67. I'll be pushing out a new gem release shortly.

Fyi, this somehow broke one of our Redmine plugins which still uses httparty in version 0.14 running in our internal Redmine instance:

An error occurred while installing bigdecimal (3.1.7), and Bundler cannot continue.

In Gemfile
  httparty was resolved 0.14.0, which depends on
    multi_xml as resolved o 0.7.1, which depends on
      bigdecimal

As httparty imports multi_xml >= 0.5.6, we could fix it by specifically adding version 0.6.0 of multi_xml to our gemfile.

@sibbl What error do you get when you try to gem install bigdecimal?
