SQLite can invoke JavaScript conflict and filter callbacks while applying a changeset. Copy the input first so detaching or modifying its backing buffer during a callback does not affect the active operation. Signed-off-by: Matteo Collina <hello@matteocollina.com>
Refactor: only copy the changeset before applying it when a filter or onConflict callback is present, since SQLite can only invoke JavaScript mid-apply in that case. Without callbacks, the input buffer cannot be detached or modified during sqlite3changeset_apply(), so no copy is needed and the buffer is passed through directly.
