Description

Fixes the two sizes_to_offsets call sites introduced by #23403 that were not updated when #23642 made memory resources explicit.

The calls preserve existing allocation behavior: mr remains the output resource and temp_mr is used for the temporary device scalar allocated by the scan.

Validation

  • pre-commit hooks (including clang-format)
  • fresh CUDA 12.9 devcontainer configure/build started; unicode_normalize.cu compilation is in progress

Closes #23825

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • CI/Build Improvements
    • Added a reusable and manually triggerable workflow for building cuDF Spark JNI artifacts with selectable repository revisions.
    • Updated pull request and test workflows to use the new cuDF Spark JNI build process.
    • Replaced the previous Spark Rapids JNI workflow with the new build workflow.
  • Bug Fixes
    • Improved memory-resource handling during Unicode normalization operations.

Walkthrough

The changes add a reusable cudf-spark-jni build workflow, update PR and test workflow callers, remove the previous JNI workflow, and pass memory resources to Unicode normalization scans.

Changes

cudf-spark-jni workflow migration

Layer / File(s) Summary
Workflow definition and repository selection
.github/workflows/cudf-spark-jni.yaml
Adds manual and reusable workflow inputs, checks out cuDF and cudf-spark-jni, and derives the JNI revision from RAPIDS_BRANCH when no revision is supplied.
Build and cache configuration
.github/workflows/cudf-spark-jni.yaml
Replaces the JNI cuDF checkout, configures AWS credentials and distributed sccache, and builds with GDS enabled for CUDA architecture 75.
Workflow caller migration
.github/workflows/pr.yaml, .github/workflows/test.yaml, .github/workflows/spark-rapids-jni.yaml
Renames the PR job, invokes cudf-spark-jni.yaml, forwards cuDF revisions, adds the reusable test job, and removes the previous workflow.

Unicode normalization memory resources

Layer / File(s) Summary
Normalization scan resource arguments
cpp/src/text/unicode_normalize.cu
Passes {mr, temp_mr} to both sizes_to_offsets calls without changing scan inputs, outputs, or total-count behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 514be

The PR updates Unicode normalization allocation routing and replaces the JNI CI workflow. The CI replacement can execute mutable source and tooling with AWS credentials and shared cache access, and it currently has an actionlint configuration failure, so the workflow hardening and validation issues should be resolved or explicitly accepted before merge.

Register the custom runner label with actionlint.

Add linux-amd64-cpu8 to actionlint.yaml under runner-label, or use an accepted label. Otherwise, actionlint fails on .github/workflows/cudf-spark-jni.yaml:33.

Security Misconfiguration (CWE-829): Inclusion of Functionality from Untrusted Control Sphere

Reachability: Internal · Exploitability: Difficult

Pin executable workflow dependencies to immutable identities.

The container image, gha-tools download, and setup-sccache-dist action use mutable references. Pin each dependency to an approved immutable digest, release, or commit SHA. Verify the gha-tools checksum before extraction. These artifacts can execute after AWS credentials are configured.

Add tests for both memory-resource paths.

The existing normalization stream test exercises the code path but does not verify allocator routing. Add unit tests for create_unicode_normalizer and normalize_unicode with distinct tracking resources. Verify that mr receives output allocations and temp_mr receives the scan temporary allocation. Add a unit benchmark for this normalization path.

As per coding guidelines, add unit tests and unit benchmarks.

Ah yes I had my agent looking at this then I stepped away. The other is approved so let's use that.
