From: "nagachika (Tomoyuki Chikanaga) via ruby-core" Date: 2023-03-25T01:56:00+00:00 Subject: [ruby-core:113006] [Ruby master Bug#18779] `GC.compact` and other compaction related methods should be defined as rb_f_notimplement on non supported platforms. Issue #18779 has been updated by nagachika (Tomoyuki Chikanaga). MEMO: It seems that #18829 is required to be backported preceded for this issue. ---------------------------------------- Bug #18779: `GC.compact` and other compaction related methods should be defined as rb_f_notimplement on non supported platforms. https://bugs.ruby-lang.org/issues/18779#change-102540 * Author: byroot (Jean Boussier) * Status: Closed * Priority: Normal * Backport: 2.7: WONTFIX, 3.0: REQUIRED, 3.1: REQUIRED ---------------------------------------- I received several bug report on native gems using `GC.verify_compaction_references` in their test suite. Examples: - https://github.com/msgpack/msgpack-ruby/pull/275/files - https://github.com/Shopify/bootsnap/pull/414/files I think that when `!GC_COMPACTION_SUPPORTED`, rather than raise `NotImplementedError`, we should instead define these methods as `rb_f_notimplement` like `Process.fork` on Windows. This way `GC.respond_to?(:compact)` would be a proper way to test for compaction support. Unfortunately, these methods are defined through `.rb` files with `Primitive`, and I don't know wether it's possible to check `GC_COMPACTION_SUPPORTED` from there, nor if it's possible to define a `rb_f_notimplement` method. cc @tenderlovemaking -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
