ruby.git/test/rubygems/test_gem_util_atomic_file_writer.rb, branch master The Ruby Programming Language [ruby/rubygems] Add missing `.binmode` for `Gem::AtomicFileWriter` 2026-01-19T07:10:42+00:00 Sutou Kouhei kou@clear-code.com 2026-01-18T13:48:42+00:00 fb75e99efea67ad3c2f802817345f749ffaf202c In https://github.com/ruby/rubygems/pull/9202, I commented that `temp_file.binmode` is redundant. But I was wrong. We need `temp_file.binmode` even when we specify `File::BINARY`. Sorry. https://github.com/ruby/rubygems/commit/d9f1f5c6a6
