Abstract: A method and apparatus of a device that changes the importance of a daemon process is described. In an exemplary embodiment, the device receives a message from a user process destined for daemon process, wherein the daemon process executes independently of the user process and the first daemon process communicates messages with other executing processes. The device further determines if the first message indicates that the importance of the first daemon process can be changed. If the first message indicates the importance of the first daemon process can be changed, the device changes the importance of the first daemon process. The device additionally forwards the first message to the first daemon process.

Abstract: A method and apparatus of a device that captures a stackshot of an executing process is described. In an exemplary embodiment, the device detects an interrupt of the process occurring during the execution of the process, where the process execution can be in a kernel space and user space, and the interrupt occurs during the user space. The device further determines whether to capture a stackshot during the interrupt using a penalty function. If the stackshot is to be captured, the device captures the stackshot and saves the stackshot.

Abstract: A method and an apparatus to dynamically distribute privileges among a plurality of processes are described. Each process may have attributes including a privilege to control access to processing resources. A first process may be running with a first privilege prohibited from access to a processing resource. A second process may be running with a second privilege allowed to access the processing resource. The first process may receive a request from the second process to perform a data processing task for the second process. In response, the second privilege may be dynamically transferred to the first process to allow the first process to access the processing resource. The first process may perform operations for the data processing task with the second privilege transferred from the second process.

Abstract: An electronic device: displays a first window in a display area; and detects a first user input associated with one or more edges of the first window. In response to detecting the first user input, and in accordance with a determination that the first user input corresponds to a first input type, the device resizes one or more dimensions of the first window that correspond to the one or more edges of the first window based on a movement vector associated with the first user input. In response to detecting the first user input, and in accordance with a determination that the first user input corresponds to a second input type, the device moves the one or more edges of the first window to one or more corresponding edges of the display area while maintaining respective one or more opposite edges of the first window.

Abstract: An electronic device: displays a first window and a second window within a display area, the first window having a first edge parallel to a second edge of the second window; and detects an input moving the first edge toward the second edge. In response to detecting the input, the device: pairs the first edge to the second edge such that the first window stops moving before it overlaps the second window when the user input satisfies pairing criteria, the pairing criteria include a first pairing criterion that is met when the input corresponds to movement of the first edge toward the second edge that deviates from a predefined axis by less than an angular threshold value; and continues the movement of the first window based on the input so that the first window overlaps the second window when the user input does not satisfy the pairing criteria.
