Frozen string errors in ruby 3.4

[hlascelles]

Ruby 3.4 emits Warnings for this gem as it modifies strings, which may be frozen in the future.

This line:

fog-aws/lib/fog/aws/signaturev4.rb

Line 112 in a7a4a00

canonical_headers << "#{key.to_s.downcase}:#{headers[key].to_s.strip}\n"

Hope that makes sense!

@hlascelles thanks. Looking at the code, it appears that canonical_headers is declared as a non-frozen/mutable string via +'', which I thought should prevent that issue for the line you mentioned. Are you you on the latest version, and are you sure that is the spot where the frozen warning is originating? Definitely welcome fixes for this and/or more info so we can track it down and fix it. Thanks!
