2025-12-03Rename `rb_obj_exivar_p` -> `rb_obj_gen_fields_p`Jean Boussier
The "EXIVAR" terminology has been replaced by "gen fields" AKA "generic fields". Exivar implies variable, but generic fields include more than just variables, e.g. `object_id`.

2025-08-12Allow encodings to be autoloaded through transcoding functionsLuke Gruber
Make sure VM lock is not held when calling `load_transcoder_entry`, as that causes deadlock inside ractors. `String#encode` now works inside ractors, among others. Atomic load the rb_encoding_list Without this, wbcheck would sometimes hit a missing write barrier.

2025-07-21Remove dsymbol_fstr_hashPeter Zhu
We don't need to delay the freeing of the fstr for the symbol if we store the hash of the fstr in the dynamic symbol and we use compare-by-identity for removing the dynamic symbol from the sym_set.
2025-07-18Remove dead post-hoc rehash checkAlan Wu
Hash#rehash checks whether the hash is iterating, and with VWA, RHASH_ST_TABLE() always returns the same thing for the same hash. RHASH_ST_TABLE(VALUE h) { return (st_table *)((uintptr_t)h + sizeof(struct RHash)); } So this check can never fail and raise an exception. Remove it.
2025-07-18Remove rehash checking TODO (GH-13919)Erik Berlin
Hash#rehash checks for rehash during iteration, and there seems to be no efficient way to check for it after the fact, so remove the TODO.

2025-06-24Fix write barriers in rb_hash_add_new_elementJohn Hawthorn
The write barriers must be run after the st_update callback returns, as the objects are not on the object until then and there may be allocation when there is a new object inserted. This is hard to reproduce, and I haven't seen an actual crash due to it, but it is detected by wbcheck RUBY_GC_LIBRARY=wbcheck WBCHECK_VERIFY_AFTER_WB=1 ./miniruby -e '("a".."zz").uniq.to_a' WBCHECK ERROR: Missed write barrier detected! Parent object: 0x720db01f99c0 (wb_protected: true) rb_obj_info_dump: 0x0000720db01f99c0 T_HASH/[S] 18 Reference counts - snapshot: 32, writebarrier: 2, current: 36, missed: 2 Missing reference to: 0x716db02e3450 rb_obj_info_dump: 0x0000716db02e3450 T_STRING/String len: 1, capa: 15 "q" Missing reference to: 0x716db02e3450 rb_obj_info_dump: 0x0000716db02e3450 T_STRING/String len: 1, capa: 15 "q" A part of why this is hard to reproduce and it's unlikely to crash is that the insertion only rarely allocates.

2025-05-22[Bug #21357] Fix crash in Hash#merge with blockDaniel Colson
Prior to https://github.com/ruby/ruby/commit/49b306ecb9e2e9e06e0b1590bacc5f4b38169c3c the `optional_arg` passed from `rb_hash_update_block_i` to `tbl_update` was a hash value (i.e. a VALUE). After that commit it changed to an `update_call_args`. If the block sets or changes the value, `tbl_update_modify` will set the `arg.value` back to an actual value and we won't crash. But in the case where the block returns the original value we end up calling `RB_OBJ_WRITTEN` with the `update_call_args` which is not expected and may crash. `arg.value` appears to only be used to pass to `RB_OBJ_WRITTEN` (others who need the `update_call_args` get it from `arg.arg`), so I don't think it needs to be set to anything upfront. And `tbl_update_modify` will set the `arg.value` in the cases we need the write barrier. Notes: Merged: https://github.com/ruby/ruby/pull/13404

2025-04-28Support Marshal.{dump,load} for core SetJeremy Evans
This was missed when adding core Set, because it's handled implicitly for T_OBJECT. Keep marshal compatibility between core Set and stdlib Set, so you can unmarshal core Set with stdlib Set and vice versa.
