Abstract: Developers receive automatically designated property change events which caused invalidation of a rendered frame. Some embodiments control display invalidation in part by identifying higher-level frame bounding events in an execution trace, and applying at least one display invalidation constituency filter to lower-level thread events within a frame creation period, thereby obtaining a display invalidation constituency sequence of one or more display invalidation events. The sequence may include a layout property change event and/or a render property change event which invalidated the frame. An initial part of the sequence is designated as a display frame creation cause. Displayed frame invalidation is controlled by altering the display invalidation constituency, e.g., by manual or automated layout/render property change event elimination or event sequence location change, by a reduction in computational resource usage (e.g.

Abstract: Technologies are disclosed for providing developers with rule output indicating that issues are or may be present in the code they are developing. Such rule output can include or be accompanied by guidelines and/or best practices structured to aid developers in becoming aware of and resolving the issues. In one example, this involves identifying the issues, making available a mechanism of further investigating the issues, and providing best practices and/or recommended solutions for the issues. Finally, the technologies disclosed may automate application of the recommended solutions. The notifications and accompanying guidance/automation and the like can be provided at design-time, compile-time, and/or run-time with the notifications and accompanying guidance/automation integrated into editors, compilers, debuggers, and other development environment tools providing true real-time and in situ development experience.

Abstract: A performance state machine is controlled in part by identifying notifications from an execution trace of an application program, through rapid automatic comparison of trace events to notification events for notification categories. Some notification categories include application startup, page outline load, page data load start, page data load finish, page to page transition, application input, window size change, media query, binding update, page background task start, page background task finish, developer-defined scenario start, and developer-defined scenario finish. Notifications may reflect heuristics such as the time from startup to first frame submission. A state is placed in the performance state machine for each identified notification, with aggregate application performance data for each transition between identified notifications.
