Package: kitty Version: 0.48.2-1.1 Severity: normal Tags: patch X-Debbugs-Cc: [email protected]
Dear Maintainer, Tests fail in restricted or containerized build environments where cgroup process tree memory accounting is restricted or returns 0. Specifically `ChildMemoryTest` fails because `memory_used_by_process_tree_rooted_at` returns <= 0. I have attached a patch (0018-skip-memory-tests-containers.patch) that checks if memory tracking is functional in `setUpClass` and skips the test if it is unavailable, rather than failing the build. This is currently applied downstream in Ubuntu.

Description: Skip child process memory tests in restricted environments The ChildMemoryTest relies on cgroups to track process tree memory. In isolated build environments (like sbuild or Launchpad builders), this tracking is often unavailable or restricted, causing the memory check to return 0 and the test to fail. This patch catches the constraint and skips the test gracefully instead of failing the build.
