From d5bdaf026cba1727da0debabace8be7c1f5a4cea Mon Sep 17 00:00:00 2001 From: Serhii Savchuk Date: Thu, 21 May 2026 22:49:25 +0300 Subject: [PATCH 01/11] fix(vec): drop dead null-shift loop in ray_vec_insert_at MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The shift loop at vec.c:571-585 was vestigial — left over from when nulls were tracked via a separate bitmap. Today every vec type that accepts HAS_NULLS encodes its null marker IN the payload via a type-specific sentinel (NULL_I64 / NULL_I32 / NULL_F64 / NaN / etc., see sentinel_is_null + ray_vec_is_null comment "Sentinels are the sole source of truth"). The memmove at line 559 already moved every payload byte, including those sentinels, to its new slot. The shift loop then read ray_vec_is_null(v, i) on a slot whose memory had just become the *next* slot's data, mis-identified the moved sentinel as still sitting at the old index, and called ray_vec_set_null_checked(v, i+1) which wrote NULL_* on top of the real (correctly-moved) value at i+1. Reproduced by test_vec_insert_at_shift_nulls: build [10, null, 30], insert 99 at index 1; expected [10, 99, null, 30], actual [10, 99, null, null(clobbered)]. Fix: delete the loop. Updated the regression test (which had been asserting the buggy output to make a green check) to assert [10, 99, null, 30] correctly — fails before this fix, passes after.
