描述

By analogy with standard file open modes. Useful modes include

  • read-only (get a database that exists, but don't save changes back)
  • force the database being opened actually exists (crash if absent)
  • force the database being opened is fresh (crash if exists)
  • overwrite the database being opened with a fresh one (truncate on open if exists)

研究方向
Examine the current implementation of bayeslite open in the repository (likely in a file like bayeslite.py). Understand how it currently opens a database and what parameters it accepts. Then implement the four requested open modes: read only, crash if absent, crash if exists, and overwrite (truncate). Ensure that the new modes are integrated cleanly into the existing function signature and that error handling is appropriate for invalid parameters. Check the issue comments for any additional context or suggestions from maintainers.
