Adds paginated Python package catalogs through a shared action on repository and repository-version viewsets:

GET /repositories/python/python/{repository_pk}/packages/ browses the latest complete snapshot.
GET /repositories/python/python/{repository_pk}/versions/{number}/packages/ browses a specific complete snapshot.

Each row represents one normalized package name, with name filtering, ordering, and a pagination count of distinct names. Each stored version returns version and last_updated; its update time is the newest content creation time across that version's files in the selected snapshot. Wheels and sdists of the same version share one entry, while rebuilds retain their stored version strings.

Package metadata comes from the highest PEP 440 version, preferring an sdist when available, and is loaded in bulk for the current page. The actions enforce repository permissions and domain boundaries. Missing or incomplete snapshots return 404. Snapshot selection uses the resource URL, so no repository_version query parameter is needed.

Replaces #1359, originally implemented by @TenSt. The original commit retains TenSt's authorship, AI attribution, and cherry-pick provenance.

Closes #1358.

Validation on pulpcore 3.123.2: 9 catalog functional/schema/domain cases pass in isolated oci-env agent environments. Python, pulpcore, and pulp-file clients were regenerated. Ruff lint/format checks and the draft documentation build pass.

Commits are cleanly separated with meaningful messages, preserving the original contribution.
A changelog entry has been added.
Follows the Pulp policy on AI Usage, with AI attribution in commit messages.
User documentation and test coverage have been added.

New Features
- Browse Python packages in a repository’s latest state or a specific repository version through the REST API.
- View package metadata, available versions, and version update times. Filter, sort, and paginate catalog results.
- Missing or incomplete repository snapshots return a not-found response.

          Add a paginated repository endpoint that lists Python packages.

795a381

Clients can walk every package in a repository version. Each row is one package name, and each stored version is one entry.

Closes pulp#1358.

Assisted-By: Cursor
(cherry picked from commit bc2c3d8)


          Move the Python package catalog into a nested read-only viewset

d96e96c

Give package listings their own serializer, name filters, ordering, and
pagination while retaining the repository packages URL. Resolve snapshots
with pulpcore's resource helpers and reject incomplete or unrelated versions.
Use the repository-version content API instead of duplicating membership
and URI resolution logic, and enforce the parent repository's domain.

Add regression coverage for filtering, generated clients, snapshot selection,
repository permissions, incomplete versions, and domain isolation. Remove
unrelated workspace exclusions and whitespace changes from the original PR.

Ref pulp#1358.

Walkthrough

The change adds repository and repository-version package catalog endpoints. The endpoints assemble package and version data from repository content, with filtering, ordering, and pagination. The change also adds functional tests and user documentation.

Changes: Python Package Catalog API

Layer / File(s)	Summary
Package aggregation and response shape `pulp_python/app/catalog.py`, `pulp_python/app/serializers.py`	Groups content by normalized package name, selects representative metadata, and assembles package entries with version timestamps.
Repository endpoints and snapshot selection `pulp_python/app/viewsets.py`, `pulp_python/app/pypi/views.py`, `pulp_python/tests/functional/api/test_catalog.py`, `docs/user/guides/catalog.md`, `docs/user/guides/_SUMMARY.md`, `docs/index.md`, `CHANGES/1358.feature`	Adds package actions for repositories and repository versions, with filtering, ordering, pagination, domain checks, and existing repository-view permissions. Adds functional coverage and documents the endpoints. The Simple API adds a secondary name ordering key.

Explanation

Issue #1358 requires a repository package endpoint with one row per name_normalized, pagination, the name_normalized__istartswith filter, and package data that includes name, name_normalized, and versions. PythonRepositoryPackagesMixin, PythonRepositoryPackageFilter, package_catalog_queryset, and assemble_package_index implement these requirements. Functional tests cover grouping, pagination, filtering, response data, permissions, and snapshot behavior. The repository action uses the latest complete snapshot.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #1358. The repository-version action, metadata selection, version timestamps, serializers, access policies, documentation, changelog, and tests support the package catalog API. No unrelated change is demonstrated.

Full details: Description check

Explanation

The pull request description is complete. It explains the feature, endpoints, behavior, filtering, pagination, metadata selection, error handling, permissions, testing, documentation, changelog, AI policy, and linked issue. The checklist is filled in.

Explanation

Docstring coverage is 78.57% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 14 functions across 5 files.

Optimize Python repository-version membership queries #1458

Draft


          Fix catalog tests across supported pulpcore versions

1f36c54

Check distinct-name pagination, returned version metadata, and deferred
column loading without assuming how pulpcore selects snapshot content.
This fixes the lowerbounds failure on pulpcore 3.105.25 while keeping
coverage for the catalog's query behavior.

Defer unused large metadata fields and load descriptions only for each
package's newest version. Remove the added AGENTS.md guidance as requested.

          Share the Python package catalog across repository snapshots

3737d4b

Expose packages through a shared read-only action on Python repositories and
repository versions. Select snapshots from resource URLs and inherit the
parent viewsets' permission checks instead of maintaining a separate endpoint.

Return last_updated for each stored package version instead of
license_expression. Compute update times across the snapshot's files
independently from representative metadata, retaining bulk metadata loading.

Update documentation and coverage for both URLs, generated clients, snapshot
timestamps, schema, permissions, and domain isolation.

Ref pulp#1358.

          Keep package catalog changes scoped to the catalog

aeb1dc0

Restore the existing publication tests and PyPI access-policy initialization.
Keep the catalog's domain isolation and permission checks alongside the other
catalog tests instead of changing the existing domain test module.

Ref pulp#1358.

Generated-By: Codex


          Simplify catalog coverage around functional API tests

12d265d

Remove the catalog unit tests and consolidate overlapping functional cases.
Reuse repository, sync, content, and user fixtures with generated API clients,
keeping coverage for pagination, filters, versions, snapshots, and permissions.
