Techniques are disclosed relating to maintaining device security associated with reduced power modes. In some embodiments, a computing device receives a request to place the computing device in a reduced power mode in which a first memory of the computing device is powered off. Based on the request, the computing device offloads a memory page from the first memory to a second memory such that the offloading includes encrypting the memory page. Based on a request to resume from the reduced power mode, the computing device restores the memory page from the second memory to the first memory such that the restoring includes decrypting the encrypted memory page. After initiating the restoring, the computing device presents a user authentication prompt asking for a user credential.

Secure reduced power mode

In an embodiment, a device may include an attention detection service. The attention detection service may monitor various peripheral devices in the device for indications that a user is paying attention to the device. Various clients may register for notification of attention detection and attention lost (attention no longer detected) events, or may poll the service for the events. If a user is not paying attention to the device, it may be possible to take various actions to permit reduced energy consumption.

Attention detection service

A system is described to create and transmit a streamable ZIP file container. The streamable ZIP file container contains stream metadata, files, and a central directory. The stream metadata, files, and central directory can be saved in a contiguous stream without any intervening bytes. When the streamable ZIP file container is read by a client device that supports streamable ZIP file containers, the client device can exit the data stream without receiving the central directory. Interruptions during transmission of the ZIP file container can be resumed.

Streaming zip

A method and an apparatus that generate a request from a first thread of a process using a first stack for a second thread of the process to execute a code are described. Based on the request, the second thread executes the code using the first stack. Subsequent to the execution of the code, the first thread receives a return of the request using the first stack.

Method and apparatus to migrate stacks for thread execution

Disclosed herein is a technique for managing disk space in user devices. A disk space manager is configured to manage the disk space by requesting clients running on the user device to free up disk space. The clients receive the requests and respond to the requests by deleting their own data to free up the requested disk space.

Intelligent disk space manager

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transferring electronic data. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of identifying a data item to be chunked; determining the type of the data item; determining whether the type of the data item is one of a specified one or more types; if it is determined that the type of the data item is not one of the specified one or more types, performing a first chunking of the data item; and if it is determined that the type of the data item is one of the specified one or more types, performing a second chunking of the data item that is based on the particular content portions of the data item.

Content based file chunking

Systems, methods, and non-transitory computer-readable storage media for updating software applications installed on client computing devices, creating a manifest file describing the differences between multiple versions of application archives present in an application distribution system, and coordinating an update process for updating the applications on the client computing devices are disclosed. A scheme of hard-linking to existing files, downloading new files, and erasing unwanted files can be used.

System and method for updating application archive files

A method and apparatus for storing a function specification file is described. In an exemplary method, the function specification field is capable for providing other software to facilitate execution of an application in a second operating system with the presence of a first operating system and the application is compiled for the first operating system. In another exemplary method, a preprocessor receives the function specification file comprising function definition data for a library function. The preprocessor processes the function definition data to generate header information and function code for the function. In another exemplary method, the preprocessor generates an automatic logging framework for the interposing library based on the function definition data. Further, a function in an interposing library logs calls to a corresponding library function.

Specification files for call translation and trace

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data according to permissions. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of identifying a version of a data item to be stored; determining permissions associated with the version of the data item; and storing the version of the data item at a storage location that is based on the determined permissions.
