    • A method and system for automatic extension of a distributed numeric range in a multi-master system are described. In one embodiment, each of a plurality of master servers is provided with a unique range of numeric values that can be assigned to clients. Each master server can dynamically extend its associated range when the range is about to be exhausted. For example, a first master server can send a range request to a second master server to obtain additional numeric values when the number of values in its associated range is below a threshold. After receipt of the additional numeric values from the second master server, the first master server updates its associated range and assigns the additional numeric values to the clients.
    • 描述了一种用于在多主系统中自动扩展分布式数字范围的方法和系统。 在一个实施例中,向多个主服务器中的每一个提供可分配给客户端的唯一范围的数值。 每个主服务器可以在范围即将耗尽时动态扩展其关联的范围。 例如,当相关范围中的值的数量低于阈值时,第一主服务器可以向第二主服务器发送范围请求以获得附加的数值。 在从第二主服务器接收到附加数值之后,第一主服务器更新其关联的范围,并向客户端分配附加数值。

    • The present invention allows Red Hat Package Manager (RPM) systems to work with non-RPM packages. In particular, the present invention provides for installing an RPM subsystem on a system that has its own native packaging subsystem. The RPM subsystem is initially delivered as a package wrapped in the non-RPM format of the native packaging system and installed. An administrator may then install RPM packages using the RPM tools of the RPM subsystem. When an RPM package is installed, the RPM subsystem is also configured to create a stub entry in the native packaging, non-RPM system. The stub entry may contain the normal package information, such as name, version, description, as well as a list of files contained in a package. The stub may also contain uninstallation logic, which serves as a “callback” into the RPM subsystem during package removal and causes the RPM subsystem to remove the package when invoked. Removal of a RPM package via RPM tools also causes the removal of the stub entry. Accordingly, both the RPM subsystem and native packaging, non-RPM subsystem may have consistent states.
    • 本发明允许Red Hat软件包管理器(RPM)系统使用非RPM软件包。 特别地,本发明提供了在具有其自己的本地封装子系统的系统上安装RPM子系统。 RPM子系统最初以包装在本机包装系统的非RPM格式的包装方式进行交付并进行安装。 然后,管理员可以使用RPM子系统的RPM工具来安装RPM软件包。 当安装RPM软件包时,RPM子系统也被配置为在本机包装非RPM系统中创建存根条目。 存根条目可能包含正常的包信息,例如名称,版本,描述,以及包中包含的文件列表。 存根还可能包含卸载逻辑,它在软件包删除期间用作RPM子系统的“回调”,并导致RPM子系统在调用时删除该包。 通过RPM工具删除RPM包也会导致删除存根条目。 因此,RPM子系统和本机包装,非RPM子系统可以具有一致的状态。
