Abstract: Techniques of data flow control are disclosed herein. One example technique includes upon receiving a notification indicating a change to a content item in a source shard, parsing the content item to extract data representing attributes of the content item and identifying a partition of the system-wide index based on the extracted data representing the attributes of the content item. The example technique can also include transmitting, to a token issuer, a request for a token that represents a permission to write to the identified partition of the system-wide index and upon receiving a token issued by the token issuer in response to the transmitted request, transmitting the extracted data representing the attributes of the content item along with the received token to write the extracted data in the partition of the system-wide index.

Abstract: A method includes detecting user interaction with a first control of a user interface, identifying a property of the first control, and storing data representing the property of the first control in a memory. The method further includes dynamically generating an event for the first control by use of the property of the first control upon detecting user interaction with a second control and upon detecting an absence of an event corresponding to the first control being generated with respect to a user interface test program. An action responsive to the dynamically generated event is stored in an event log.

Abstract: A hierarchical software update distribution system and method for distributing software updates is presented. The update distribution system includes a root update service node and at least one update service node. In an update distribution system, each update service node, except the root update service node, has one parent update service node. Each update service node may function as a parent update service node to child update service nodes.

Abstract: A compile-time data store that contains arbitrary data types is accessed via methods that ensure type safety. A type construct (e.g., a C++ template) is instantiated at compile time and generates a data store that contains arbitrarily-typed data objects, such as integers, characters, pointers and so forth. The construct includes a Put method to put any element (object) of a listed type (e.g., of a typelist) in the data store, and a Get method to retrieve the element from the data store. The Put method maintains a type index in association with each stored in the data store. The Get method validates that the type of object that was requested in the call to the Get method matches the object type that was stored in the Put method. When run, the Get method returns the element data upon a type match, otherwise the Get method generates an exception.

Abstract: A method for controlling the update installation behavior of a computing device according to installation attributes is presented. When present, a mandatory installation attribute associated with a software update causes the installation process executed on the computing device to disallow a user to selectively not install the software update. A priority installation attribute causes the computing device to request a higher amount of network bandwidth for obtaining the software update's content for installation on the client computing device. A deadline installation attribute associated with the software update causes the computing device to permit a user to selectively not install the software update until an associated deadline passes, at which time the software update is installed without further user interaction.
