ZODB context manager

Installation

pip install zodb-cm

ZConnection()

• Provides a ZODB connection with auto-abort (default).
• Provides a tuple of connection and root object:

      with ZConnection(db) as cx, root:
          root.one = "ok"

• ZConnection implements a connection context manager.
• Transaction context managers in contrast do auto-commit:
  1. with db.transaction() as connection, or
  2. with cx.transaction_manager as transaction, or
  3. with transaction.manager as transaction (for the thread-local transaction manager)
