YjyJeff opened a new issue, #3031: URL: https://github.com/apache/arrow-rs/issues/3031
**Describe the bug** The [`nullif`] function in `compute/kernels/boolean.rs` has incorrect `valid_count` when the left's null_buffer is None. [`nullif`]: https://github.com/apache/arrow-rs/blob/master/arrow/src/compute/kernels/boolean.rs#L525 **To Reproduce** ```rust let a = Int32Array::from(vec![Some(15), Some(7), Some(8), Some(1), Some(9)]); let comp = BooleanArray::from(vec![Some(false), None, Some(true), Some(false), None]); let res = nullif(&a, &comp).unwrap(); // panic here ``` **Why it happens** `bitwise_unary_op_helper` will apply the `op` to the remainder bytes, the problem happens here. `valid_count` will take the ones that should be ignored into consideration. **Solution** ```rust let left = Bitmap::new(len); bitwise_bin_op_helper(left.buffer(), 0, &right, right_offset, len, |l, r| { let t = l & !r; valid_count += t.count_ones() as usize; t }) ``` -- This is an automated message from the Apache Git Service.
