[Ravikirar]

Summary

• Add a YAML package collection format with semantic versioning.
• Support package lists, descriptions, configurations, and collection dependencies.
• Add local collection import/export and version management.
• Resolve collection dependencies in dependency order.
• Detect missing dependencies and circular dependency chains.
• Validate manifests before installation.
• Install resolved collections through apt-get.
• Support pinned package syntax such as package@version.
• Add example collections and user documentation.
• Add unit tests using temporary registries and a fake package executor.

Closes #34

Validation

• 11 unit tests passed.
• tools/collection_manager.py test coverage: 92%.
• Validate → import → dependency planning → export flow was smoke-tested.
• Tests do not perform privileged package installation.

Examples

python3 tools/collection_manager.py validate collections/examples/data-science-stack.yaml

python3 tools/collection_manager.py import collections/examples/base-development.yaml
python3 tools/collection_manager.py import collections/examples/data-science-stack.yaml

python3 tools/collection_manager.py plan data-science-stack

sudo python3 tools/collection_manager.py install data-science-stack --yes

python3 tools/collection_manager.py export data-science-stack ./data-science-stack.yaml

📝 Walkthrough

Walkthrough

The pull request adds a versioned package collection manager. It supports YAML validation, filesystem storage, dependency resolution, APT installation, CLI commands, example collections, documentation, and unit tests.

Changes

Package Collections

Layer / File(s)	Summary
Collection contracts and validation tools/collection_manager.py, collections/examples/*.yaml	Defines semantic versions, dependencies, collection metadata, validation rules, YAML loading, and two example manifests.
Registry resolution and installation tools/collection_manager.py	Adds versioned filesystem storage, dependency planning, package deduplication, APT argument translation, and installation handling.
CLI commands and error reporting tools/collection_manager.py	Adds commands for validation, import, export, listing, display, planning, and installation. CLI errors return exit code 2.
Tests and usage documentation tests/test_collection_manager.py, docs/package-collections.md	Adds workflow tests and documents collection manifests, CLI usage, dependency resolution, validation, and test execution.

Merge Risk: 🟡 Moderate · up to bdc72

Version resolution and installation can fail or select the wrong package collection, while the documented installation command may not find imported collections. These issues should be fixed before merging.

Full details: Linked Issues check

Explanation

Most requirements for issue #34 are implemented. load_collection defines and validates YAML collections, CollectionStore provides versioned import/export and resolution, plan resolves dependencies and detects cycles or missing collections, install_collection installs the complete deduplicated package plan through apt-get, and tests, documentation, and examples are included. However, semantic-version ordering is incorrect. Version uses @dataclass(order=True), which compares prerelease as a normal string. This makes 1.0.0-alpha sort after 1.0.0, so version resolution can select a prerelease over the final release. Numeric prerelease identifiers also use lexicographic ordering.

Resolution

Implement Semantic Version precedence for Version comparisons, including final releases after prereleases and numeric prerelease identifiers. Add unit tests for prerelease ordering and dependency resolution. Then verify the documented coverage target remains above 80%.

Full details: Docstring Coverage

Explanation

Docstring coverage is 2.63% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 38 functions across 2 files. (3 skipped: 3 unsupported.)

Inline comments:
In `@docs/package-collections.md`:
- Line 38: Update the documented privileged collection-manager command to pass
the importing user’s registry explicitly via the --store
"$HOME/.local/share/cx/collections" option before install, so
install_collection() resolves data-science-stack from the imported registry.

In `@tools/collection_manager.py`:
- Around line 245-247: Update the package collection logic around the seen set
and result list to track package names separately from requested versions.
Detect and reject any package appearing with conflicting pinned versions,
including combinations of pinned and unpinned entries, before invoking the
runner; retain only one non-conflicting package specification.
- Around line 106-108: Update _parse_package to reject malformed pinned package
specifications: allow at most one @ separator, and when present require both the
package name and version to be non-empty. Preserve the existing unsafe-entry
checks and return valid unpinned or pinned package values unchanged.
- Around line 26-31: Replace the generated ordering on Version with
semantic-version precedence: stable releases must rank above prereleases, and
prerelease identifiers must compare numerically when numeric and lexically when
non-numeric. Update constraint checks and CollectionStore.resolve() to use this
comparison, then add tests covering stable-versus-prerelease and numeric cases
such as rc.2 versus rc.10.
