PRAGMA busy_timeout=N emits its own result row, polluting the read-back parse (seed read back '20000\nupgrade-survives' → AssertionError 'seed did not commit', failing upgrade/backup/restore ops — though the INSERT actually committed). Switch _sqlite to 'sqlite3 -cmd ".timeout 20000"' which sets the busy timeout silently. install+custom already green (handshake/welcome/web/tcp PASS); this fixes the P4 lifecycle ops.

"""mumble — pre-op seed hooks (Phase 1e HC3 / Phase 2 P4 backup data-integrity).
|
|
|
|
The orchestrator runs these BEFORE each op; the matching test_<op>.py asserts post-op (assertion
|
|
only). mumble persists its server state (registered users/channels/ACLs/config) in the sqlite DB
|
|
`/data/mumble-server.sqlite`, and the recipe's backupbot hooks dump/restore exactly that file
|
|
(`sqlite3 ... ".backup backup.sqlite"` pre-hook; `mv backup.sqlite mumble-server.sqlite` restore
|
|
post-hook). So real backup data-integrity = seed a marker row into that sqlite, back up, mutate,
|
|
restore, and prove the seeded row survived — the same DB the recipe actually backs up.
|
|
|
|
The murmur server holds the DB open, so all writes use `PRAGMA busy_timeout` to wait out the
|
|
server's transient locks rather than failing with "database is locked". The marker lives in a
|
|
dedicated `ci_marker` table murmur never touches.
