Use rb_darray_insert_without_gc for heap_pages darray

2025-01-02T16:03:04+00:00

rb_darray_insert could trigger a GC, which would cause problems if it
freed pages while a new page was being inserted.

For example, the following script fails:

    GC.stress = true
    GC.auto_compact = :empty

    10.times do
      GC.verify_compaction_references(expand_heap: true, toward: :empty)
    end

It errors out with:

    'GC.verify_compaction_references': malloc: possible integer overflow (8*18446744073709551603) (ArgumentError)

Revert "Remove with_gc functions in darray"

2025-01-02T16:03:04+00:00

This reverts commit 24a740796050b72aa2d35339ba2a317d4eda7b75.

Fix MEMMOVE in rb_darray_insert

2024-12-24T14:40:12+00:00

Ruby's MEMMOVE takes in the element data type for the third argument, not
the size of the element. What this did was do sizeof(sizeof( ... )) which
always returned sizeof(size_t).

darray.h does not depend on internal/bits.h

2024-12-05T19:12:56+00:00

darray.h no longer depends on internal/bits.h, so we can remove it.
