This allows the integration tests to invoke snaps (such as juju). In more recent versions of TOX, all environment variables are cut off from the subprocess invokation. Signed-off-by: Guillaume Boutry <guillaume.boutry@canonical.com> (cherry picked from commit c906d3c)
Add RoleHandler that integrates with the role-distributor charm via the role-assignment relation. Roles use MicroOVN taxonomy: central (OVN central services), chassis (data plane), and gateway. Key design decisions: - Role assignment is a durable source of truth, re-evaluated on update-status, ovsdb-cms ready/broken, and cluster-changed events. - Applied roles are cached in StoredState for idempotency; the cache is invalidated when _dataplane_mode() mutates central outside RoleHandler. - Gateway config reads fail closed: transient ovs-vsctl failures block rather than clobbing existing ovn-cms-options from an assumed-empty value. - Relation broken keeps workload state unchanged but clears the cache and recomputes unit status. - The relation is optional; backward compatibility is preserved when no role-assignment relation exists. Assisted-By: Claude Code (claude-opus-4-6) Assisted-By: Codex (gpt-5.4-xhigh) Signed-off-by: Guillaume Boutry <guillaume.boutry@canonical.com> (cherry picked from commit 1993b74)
we cannot remove doca-openvswitch-switch as it is depended on, so we remove ovs-vsctl. openvswitch-switch is marked as held by maas so we need to force remove it. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit 697a4fe)
