摘要： Systems and methods for applying both profile and user customizations to an application user interface are provided. Profile customizations, created for a specialized use or field, are adapted to an application user interface, which has command-menu-toolbar contributions from various add-in modules. The user has access to the customizations through a user interface. Then, as a user is customizing the application, through commands, toolbars, and menus, the user customizations are tagged. A priority and group is assigned to each customization to allow for relative positioning of each customization. The difference between the user's final desired state and a reset state is computed. This difference computation is used to track the changes made to the application and to assist in resets of the customizations.

摘要： The present invention provides a method for keeping a file system in a consistent state and for creating read-only copies of a file system. Changes to the file system are tightly controlled. The file system progresses from one self-consistent state to another self-consistent state. The set of self-consistent blocks on disk that is rooted by the root inode is referred to as a consistency point. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the fsinfo block is updated by writing a new root inode for the inode file into it. Thus, as long as the root inode is not updated, the state of the file system represented on disk does not change. The present invention also creates snapshots that are read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snapshots can be created for the same file system. Unlike prior art file systems that create a clone by duplicating the entire inode file and all of the indirect blocks, the present invention duplicates only the inode that describes the inode file. A multi-bit free-block map file is used to prevent data from being overwritten on disk.

摘要： The present invention is a method for providing error correction for an array of disks using non-volatile random access memory (NV-RAM). Non-volatile RAM is used to increase the speed of RAID recovery from a disk error(s). This is accomplished by keeping a list of all disk blocks for which the parity is possibly inconsistent. Such a list of disk blocks is much smaller than the total number of parity blocks in the RAID subsystem. The total number of parity blocks in the RAID subsystem is typically in the range of hundreds of thousands of parity blocks. Knowledge of the number of parity blocks that are possibly inconsistent makes it possible to fix only those few blocks, identified in the list, in a significantly smaller amount of time than is possible in the prior art. The technique for safely writing to a RAID array with a broken disk is complicated. In this technique, data that can become corrupted is copied into NV-RAM before the potentially corrupting operation is performed.
