From 795a3814fe9fa17b29bc0bb9107128966d0ea968 Mon Sep 17 00:00:00 2001 From: TenSt Date: Tue, 6 Oct 2026 14:23:25 +0200 Subject: [PATCH 1/3] Add a paginated repository endpoint that lists Python packages. Clients can walk every package in a repository version. Each row is one package name, and each stored version is one entry. Closes #1358.

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 #1358.

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. Ref #1358.
