func CheckpointWAL ¶ added in v0.3.0

func CheckpointWAL(cortexDir string) error

CheckpointWAL runs PRAGMA wal_checkpoint(TRUNCATE) on the given cortex's SQLite database, forcing all pending WAL pages into the main file and truncating the WAL to zero bytes. Used by `noema cortex backup` so the tarball captures a consistent snapshot without a separate -wal sidecar.

This bypasses db.Open's migration runner on purpose: backup is a read- mostly operation and must not upgrade the on-disk schema as a side effect (a v1 cortex should stay at v1 after being backed up). If the database file does not exist yet, the function is a no-op — there is nothing to checkpoint on a cortex that has never been opened.
