Issue #21855 has been reported by Earlopain (Earlopain _). ---------------------------------------- Bug #21855: Bundle `win32-registry` or implement it without `fiddle` https://bugs.ruby-lang.org/issues/21855 * Author: Earlopain (Earlopain _) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- `win32-registry` (a default gem), is currently implemented via `fiddle` (a bundled gem). This makes it impossible to use under bundler without adding `fiddle` to the gemfile. In the past it has lead to issues like https://bugs.ruby-lang.org/issues/21645. It was solved by simply not using `win32-registry` anymore in `resolv` and implementing it via C (https://github.com/ruby/resolv/pull/110), although the overarching issue is still present. There is also a report for this for rubygems https://github.com/ruby/rubygems/issues/9277. This should be solved by updating the vendored `resolv` version I think. Still, the dependecy relation between `win32-registry` and `fiddle` is pretty incompatible. A default gem can't depend on a bundled gem without breaking dependency resolution. To solve this it would have to be implemented without using `fiddle`, similar to how `resolv` did it. But now that `resolv` doesn't use `win32-registry`, I don't think anything in ruby uses it anymore. So moving it to a bundled gem could also be a solution without rewriting the whole thing. Here is an issue about this in the `win32-registry` repo: https://github.com/ruby/win32-registry/issues/11 -- https://bugs.ruby-lang.org/
