Unit Tests / test (push) Successful in 12m51s
Migrate from the single-exit-per-type model (one wireguard_exit, one tor_exit, etc.) to N named connection instances, each carrying its own resource allocations and vault-backed secret refs. config_manager.py: - Connectivity v2 schema: top-level `connections` list, each entry has id, name, type, enabled, status, config, secret_ref, and allocated resources (mark, table, iface, redirect_port). - Helpers: get_connectivity / list_connections / get_connection / add_connection / update_connection / delete_connection / set_connection_status. - v1→v2 migration: promotes legacy wireguard_exit / tor fields into the new list on first load; idempotent on v2 configs. connectivity_manager.py: - Resource allocator: per-instance fwmark range 0x1000–0x1FFF, routing table range 1000+, interface names, and redirect ports 9100–9199; all tracked in config to survive restarts. - Connection CRUD: create / update / delete / list / get with vault secret refs for WireGuard private keys and Tor credentials. - Single-Tor enforcement: rejects a second tor/tor_bridge instance at creation time. - Per-instance config validation for each connection type. - apply_routes, peer wiring, and egress hookups are intentionally left unchanged in this phase; they land in later phases alongside UI. tests/test_connectivity_connections.py (new, 473 lines): - Allocator uniqueness, v1→v2 migration round-trip, CRUD lifecycle, single-Tor enforcement, and status transitions.

Tests for the connectivity v2 data model — named connection instances.
|
|
|
|
Covers the resource allocator (no mark/table/port collisions, correct iface
|
|
naming, iface vs redirect-port split), the v1→v2 migration (legacy exits →
|
|
one connection each, secret repointing, idempotency, empty case), connection
|
|
CRUD (validation, single-tor, duplicate name, secret refs not values, delete
|
|
frees resources + vault secret, delete blocked when referenced), and computed
|
|
status.state (added vs configured).
|
|
|
|
ConfigManager runs against a tmp dir; the vault is an in-memory fake. No real
|
|
Docker/iptables/subprocess is invoked (apply_routes is never called here).
