📝 Summary

Summary by CodeRabbit

  • New Features

    • Dependency YAML validation now checks naming conventions for Python project outputs and optional dependencies.
    • Validation supports files sections, including file outputs, project directories, extras tables, and extras keys.
    • Hyphenated project names are normalized consistently when evaluating expected names.
    • Clear warnings and suggested replacements are provided for names that do not match expected conventions.
  • Bug Fixes

    • Improved traversal of nested dependency YAML structures to ensure relevant entries are validated.

Walkthrough

The dependency YAML traversal now processes files sections, including outputs, extras, and Python project directories. NamingConventionsHandler is added to the dependency validation chain and ignores empty project directory names. Tests cover traversal and naming validation.

Changes

Dependency YAML naming validation

Layer / File(s) Summary
Files traversal and handler propagation
src/rapids_pre_commit_hooks/utils/dependencies_yaml.py, tests/rapids_pre_commit_hooks/utils/test_dependencies_yaml.py
Handler hooks, chained forwarding, and traversal functions now process file outputs, extras, Python project directories, and nested file items. Root traversal dispatches both files and dependencies.
Naming convention validation
src/rapids_pre_commit_hooks/dependencies/naming_conventions.py, src/rapids_pre_commit_hooks/dependencies/__init__.py, tests/rapids_pre_commit_hooks/dependencies/test_naming_conventions.py
NamingConventionsHandler excludes empty Python directories, validates naming combinations, and is added to the dependency handler chain. Tests cover valid, invalid, and integrated YAML cases.

175-204: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Resolve YAML nodes with find_yaml_node_for_span().

This test resolves nodes by index and by key lookup (root.value[0][1], files.value[0], the file_fields/extras_fields comprehensions). The structure is coupled to the document layout of each of the nine parameter cases. Add named spans for the file key, the file value, output, pyproject_dir, table, and key, then resolve them with find_yaml_node_for_span(). The optional fields can then be selected by span presence instead of by dictionary membership.

As per path instructions, "Tests for YAML-based hooks should generally use rapids_pre_commit_hooks_test_utils.find_yaml_node_for_span() rather than hard-coding a path to the desired YAML node, though some very small and trivial tests may use the nodes directly."

This is a nice change, I like it!

Everything that follows is just non-blocking commentary.


It's worth looking into this hard-coded list in the devcontainers:

if test ${#dependency_keys[@]} -eq 0; then
    dependency_keys=(py_build py_run py_test all);
fi

(rapidsai/devcontainers code link)

It's possible that that's just dead code if all the RAPIDS projects are appending _<project> already, or that it'd be broken if you discover that some projects use py_build: (no <project>) and change that while rolling out this update to the hook.

I tested like this on latest main of cuDF:

I also tried the same thing in https://github.com/NVIDIA/raft, thought that would be interested because it has a python/raft-dask and I thought the hyphen in the name might cause issues. But all worked perfectly.

Already took care of that 😁

or that it'd be broken if you discover that some projects use py_build: (no <project>)

Looks like cucim, dask-cuda, jupyterlab-nvdashboard, rapids-dask-dependency, rapids-logger, and rmm are using this convention. Let me see what the impact would be on devcontainers.
