* Fix bug where home presses were not poking user activity.Jeff Brown2010-10-181-40/+28
| | | | | | | | | | | | | | | | | We now poke user activity twice: once upon dequeueing an event for dispatch and then again just before we dispatch it. The second poke is to compensate for the fact that it can take a few seconds to identify the dispatch target (if the application is responding slowly) but we want to keep the display from going to sleep for X amount of time after the app gets a chance to actually receive the event. This mirrors pre-Gingerbread behavior. Removed some unnecessary code that filters user activity pokes when sending events to KeyGuard. We don't need this because KeyGuard already tells the power manager to disable user activity. Bug: 3101397 Change-Id: I8c3a77601fdef8f584e84cfdd11aa79da0ff51db

* Add support for secure system overlays. (DO NOT MERGE)Jeff Brown2010-10-151-2/+3
| | | | | | | | | | This change adds a new window type for secure system overlays created by the system itself from non-secure system overlays that might be created by applications that have the system alert permission. Secure views ignore the presence of secure system overlays. Bug: 3098519 Change-Id: I8f8398f4fdeb0469e5d71124c21bedf121bd8c07

* Fix an event injection bug when the policy is bypassed.Jeff Brown2010-10-111-33/+30
| | | | | | | | | | Added the concept of a "trusted" event to distinguish between events from attached input devices or trusted injectors vs. other applications. This change enables us to move certain policy decisions out of the dispatcher and into the policy itself where they can be handled more systematically.

* Added more robust tracking and cancelation of events.Jeff Brown2010-10-102-314/+389
| | | | | | | | | | | | | | | | | | | | | | This change fixes several issues where events would be dropped in the input dispatch pipeline in such a way that the dispatcher could not accurately track the state of the input device. Given more robust tracking, we can now also provide robust cancelation of input events in cases where an application might otherwise become out of sync with the event stream due to ANR, app switch, policy decisions, or forced focus transitions. Pruned some of the input dispatcher log output. Moved the responsibility for calling intercept*BeforeQueueing into the input dispatcher instead of the input reader and added support for early interception of injected events for events coming from trusted sources. This enables behaviors like injection of media keys while the screen is off, haptic feedback of injected virtual keys, so injected events become more "first class" in a way.

* | Make input dispatcher only ANR for foreground windows.Jeff Brown2010-09-151-393/+269
|/ | | | | | | | | | | | | | Redesigned the input dispatcher's ANR timeout mechanism so it is much closer to Froyo's policy. ANR is only ever signalled if the dispatcher is waiting on a window to finish processing its previous event(s) and there is new pending input. In the old code, we tracked the dispatch timeout separately for each input channel. This was somewhat complicated and also resulted in the situation where applications could ANR long after the user had pushed them into the background.

| * Replace epoll() with poll() and rename PollLoop to Looper.Jeff Brown2010-09-141-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of this change, consolidated and cleaned up the Looper API so that there are fewer distinctions between the NDK and non-NDK declarations (no need for two callback types, etc.). Removed the dependence on specific constants from sys/poll.h such as POLLIN. Instead looper.h defines events like LOOPER_EVENT_INPUT for the events that it supports. That should help make any future under-the-hood implementation changes easier. Fixed a couple of compiler warnings along the way. Change-Id: I449a7ec780bf061bdd325452f823673e2b39b6ae

* Input dispatcher ANR handling enhancements.Jeff Brown2010-09-123-501/+1874
| | | | | | | | | | | | | | | | | | | | | | | This change is essentially a rewrite of the main input dispatcher loop with the target identification folded in. Since the input dispatcher now has all of the window state, it can make better decisions about when to ANR. Added a .5 second deadline for processing app switch keys. This behavior predates Gingerbread but had not previously been ported. Fixed some timing inaccuracies in the ANR accounting that could cause applications to ANR sooner than they should have. Added a mechanism for tracking key and motion events that have been dispatched to a window so that appropriate cancelation events can be synthesized when recovering from ANR. This change helps to keep applications in sync so they don't end up with stuck buttons upon recovery from ANRs. Added more comments to describe the tricky parts of PollLoop.

Added a "filterTouchesWhenObscured" attribute to View which can be used to enable filtering of touches when the view's window is obscured. Change-Id: I936d9c85013fd2d77fb296a600528d30a29027d2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On single-touch devices, pointer up/down is signalled by a BTN_TOUCH key event. Previously we handled BTN_TOUCH immediately but some drivers may produce the sequence BTN_TOUCH, ABS_X, ABS_Y, SYN_REPORT on pointer down which caused us to emit a bad initial pointer down location. Now we wait for SYN_REPORT before reporting the up or down. On multi-touch devices, pointer up can be signalled by as little as the sequence SYN_MT_REPORT, SYN_REPORT. This change ensures that we handle this case. Added support for reading ABS_MT_PRESSURE when available. Corrected mapping of touchMajor/touchMinor on single touch devices. Minor code cleanup.

|/ | | | | | | | | | | Sometimes the wrong fd was accessed when the device was addressed by device id.

* Fix possible race conditions during channel unregistration.Jeff Brown2010-08-171-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the input dispatcher assumed that the input channel's receive pipe file descriptor was a sufficiently unique identifier for looking up input channels in its various tables. However, it can happen that an input channel is disposed and then a new input channel is immediately created that reuses the same file descriptor. Ordinarily this is not a problem, however there is a small opportunity for a race to arise in InputQueue. When InputQueue receives an input event from the dispatcher, it generates a finishedToken that encodes the channel's receive pipe fd, and a sequence number. The finishedToken is used by the ViewRoot as a handle for the event so that it can tell the InputQueue when the event has finished being processed. Here is the race: 1. InputQueue receives an input event, assigns a new finishedToken. 2. ViewRoot begins processing the input event. 3. During processing, ViewRoot unregisters the InputChannel. 4. A new InputChannel is created and is registered with the Input Queue. This InputChannel happens to have the same receive pipe fd as the one previously registered. 5. ViewRoot tells the InputQueue that it has finished processing the input event, passing along the original finishedToken. 6. InputQueue throws an exception because the finishedToken's receive pipe fd is registered but the sequence number is incorrect so it assumes that the client has called finish spuriously. The fix is to include a unique connection id within the finishedToken so that the InputQueue can accurately confirm that the token belongs to the currently registered InputChannel rather than to an old one that happened to have the same receive pipe fd. When it notices this, it ignores the spurious finish. I've also made a couple of other small changes to avoid similar races elsewhere. This patch set also includes a fix to synthesize a finished signal when the input channel is unregistered on the client side to help keep the server and client in sync.
