Added null checks in GpuSlice implementation before performing validation: - In doColumnar(listCol, startCol, lengthS): Check if all rows are null in list or start columns - In doColumnar(listCol, startCol, lengthCol): Check if all rows are null in list, start, or length columns This ensures CPU and GPU have consistent behavior when handling null inputs with negative length parameters. Improved comments to clarify the null handling behavior. Fixes #13164 Co-authored-by: pxLi <8086184+pxLi@users.noreply.github.com>

Fixed the sign-off check issue by adding the Signed-off-by line to the commit in 71251d2. Regarding the PR description check - I can see the malformed HTML comment content in the description, but I don't have the ability to directly edit the GitHub PR description to remove the |

@copilot good work, and please remember to use |
The build is failing due to network connectivity issues with Maven repositories (central.sonatype.com and repository.apache.org are blocked by firewall). This is consistent with the firewall warnings shown in the PR description. The code changes themselves are complete and ready, but the build cannot complete due to these network restrictions.

this line is too long which caused

Fixed the line length issue by breaking the long comment and condition into multiple lines in commit 4e60e36.

@copilot "build" here is the trigger phase for our internal CI. Please stop monitoring comments that only contain the word "build" |

Understood. I'll avoid responding to comments that contain only "build" since those are CI trigger phrases. |
The
test_array_slice_with_negative_lengthintegration test was failing in Scala 2.13 because the GPU and CPU implementations of theslicefunction had inconsistent behavior when handling null input data with negative length parameters.Problem
The CPU
slicefunction skips validation when input arrays or start indices contain null values and simply returns null results. However, the GPU implementation always validated the length parameter regardless of whether the input data contained nulls, causing it to throw errors when the CPU would not.For example:
slice(null_array, valid_start, -5)→ CPU returns null, GPU throws "negative length" errorslice(valid_array, null_start, -5)→ CPU returns null, GPU throws "negative length" errorSolution
Added null checks in the GPU
GpuSliceimplementation before performing validation:doColumnar(listCol, startCol, lengthS): Check if all rows are null in the list or start columns before validating the length parameterdoColumnar(listCol, startCol, lengthCol): Check if all rows are null in the list, start, or length columns before performing any validationdoColumnar(listS, startCol, lengthCol): Added missing null check for list scalarThe fix uses the existing
GpuDivModLike.mergeNulls()pattern to combine null masks from multiple columns and only proceeds with validation when there are non-null values to process.Behavior After Fix
This ensures consistent behavior between CPU and GPU implementations while preserving all existing validation logic.
Fixes #13164.
