Detailed Description

Fired exactly once per TargetImpl::commit call, marking the point at which the actual RPM transaction becomes irreversible.

This report exists to give callers (e.g. an MCP worker mediating cancellation requests) a single, backend-agnostic synchronization point: start is called before any persistent state (locks, requested locales, autoinstalled) is written or the RPM transaction begins, regardless of Legacy vs SingleTrans backend.

Returning false aborts the commit TargetImpl::commit throws TargetAbortedException. This lets a receiver (e.g. one mediating an external cancellation request) decline safely rather than relying on an external process signal racing against the point of no return.

start()

virtual bool zypp::target::CommitActiveReport::start ( const UserData & = UserData() )

inlinevirtual

Called once, synchronously, before the irreversible transaction begins.

Return false to abort the commit before anything has been touched.

end()

virtual void zypp::target::CommitActiveReport::end ( const UserData & = UserData() )

inlinevirtual

Called when all target state has been written.

Commit is done and safe.
