    摘要： Systems and methods are disclosed for tracking the lifecycle of an object across processes and for tracking the lifecycle of processes that are processing the object. A first process, P1 can generate an Action object representing work to be performed by another process, PN. The Action object can carry a payload of arbitrary information, an action handler, a handle to a response queue, and a timeout value. A token set can be requested from a kernel of an operating system. A first token in the set can be held by one process at a time. The kernel enforces that rule. The kernel can track the location of the first token. A copy of the Action object is viable for sending a response if it holds the first token. An Action Listener within P1 holds the second token of the set and uses it to validate a response received by P1 from a remote process. The remote process performs the work of the Action object and guarantees a response back to P1, through the kernel, without passing the response back through intervening processes P2 through PN-1.

    摘要： Disclosed herein is a technique for implementing a secure lock screen on a computing device. The secure lock screen is configured to permit particular applications to display their content—such as main user interfaces (UIs)—while maintaining a desired overall level of security on the computing device. Graphics contexts, which represent drawing destinations associated with the applications, are tagged with entitlement information that indicates whether or not each graphics context should be displayed on the computing device when the computing device is in a locked-mode. Specifically, an application manager tags each application that is initialized, where the tagging is based on a level of entitlement possessed by the application. In turn, a rendering server that manages the graphics contexts can identify the tagged entitlement information and display or suppress the content of the applications in accordance with their entitlements.

A first process, P1 can generate an Action object representing work to be performed by another process, PN. The Action object can carry a payload of arbitrary information, an action handler, a handle to a response queue, and a timeout value. A token set can be requested from a kernel of an operating system. A first token in the set can be held by one process at a time. The kernel enforces that rule. The kernel can track the location of the first token. A copy of the Action object is viable for sending a response if it holds the first token. An Action Listener within P1 holds the second token of the set and uses it to validate a response received by P1 from a remote process. The remote process performs the work of the Action object and guarantees a response back to P1, through the kernel, without passing the response back through intervening processes P2 through PN-1.

    摘要： An electronic device, while displaying a user interface that includes a first region corresponding to a first software application and a second region corresponding to a second software application, receives a first touch input, on a touch-sensitive display, that originates from a first location corresponding to the first region and extends to a second location corresponding to the second region. The first region includes a non-boundary region and a boundary region. In response to receiving the first touch input, when the first location corresponds to a non-boundary region of the first region, the device processes the first touch input with the first software application. When the first location corresponds to a boundary region of the first region, the device conditionally processes the first touch input with the second software application.
