    • Systems, methods, and apparatus for preventing misuse of searches of a database system are provided. This prevention of misuse of database searches can enable reliable operation of the database system, as an improper query using a regular expression will not shut down or severely affect an application process that provides access to the database system. A thread of the application process determines whether an input character characters string matches the regular expression. To prevent misuse, a computational effort of the search is tracked, and compared to a threshold value. When the threshold is exceeded, an operation of the thread is exited or stopped.
    • 提供了用于防止滥用数据库系统的搜索的系统,方法和装置。 由于使用正则表达式的不正确查询不会关闭或严重影响提供对数据库系统访问的应用程序进程,因此这种防止滥用数据库搜索可以实现数据库系统的可靠运行。 应用进程的线程确定输入的字符字符串是否与正则表达式匹配。 为了防止误用,跟踪搜索的计算努力,并将其与阈值进行比较。 当超过阈值时,退出或停止线程的操作。

    • Systems and methods for installing and upgrading application packages to an application platform. The systems and methods are particularly useful in an on-demand database service. Application packages may be uploaded to a directory by developing users (developers) for installation by subscribing users (subscribers). Alternatively, a developer may send identification information to a subscribing user to allow that user to access and install that application package created by the developer. Application packages may also be upgraded. If a developer changes the original source package, a subscriber can choose to pull into their organization the change(s) made by the publisher while preserving any data rows the subscriber had created since first importing the package. One or more flags may be set in the package definition to determine whether and to what extent customizations to a package may be made and upgraded by the subscriber and/or developer. A “manageable” field is provided to identify whether customizations to a particular object are subject to upgrade; if the package or an object in the package is marked as managed, a user is allowed to customize the package or the object, and these customizations will not be altered upon upgrading of the package. A “control” field is provided to identify whether an object may be modified by the developer and/or the subscriber. An “immutable” field is provided to identify whether an object can or cannot be altered by anyone.
    • 将应用程序包安装和升级到应用程序平台的系统和方法。 系统和方法在按需数据库服务中特别有用。 应用程序包可以通过开发用户(开发人员)上传到目录,以供订阅用户(订阅者)安装。 或者,开发者可以向订阅用户发送标识信息,以允许该用户访问并安装由开发者创建的该应用包。 应用程序包也可以升级。 如果开发人员改变原始的源码包,订阅者可以选择将发布者所做的更改拉入其组织,同时保留订阅者自从首次导入包以来创建的任何数据行。 可以在包定义中设置一个或多个标志,以确定订阅者和/或开发者是否以及在多大程度上自定义包装可以进行和升级。 提供“可管理”字段以识别对特定对象的定制是否可以升级; 如果软件包或软件包中的对象被标记为托管,则允许用户自定义软件包或对象,并且在升级软件包时不会更改这些定制。 提供“控制”字段以识别对象是否可以被开发者和/或订户修改。 提供了一个“不可变的”字段来标识对象是否可以被任何人改变。
