* fix [2835280] Add support for cancelling buffers to ANativeWindowMathias Agopian2010-10-043-5/+19
| | | | | | | | | | There is a new ANativeWindow::cancelBuffer() API that can be used to cancel any dequeued buffer, BEFORE it's been enqueued. The buffer is returned to the list of availlable buffers. dequeue and cancel are not mutually thread safe, they must be called from the same thread or external synchronization must be used.

* | Use pread() in ZipFileRO for LinuxKenny Root2010-10-041-7/+17
|/ | | | | | | | | | | | | | | | | AssetManager instances are created by zygote and passed to all its children so that they don't have to individually open frameworks-res.apk. This creates a problem for determining the current file offset when using lseek() on those files, because you can't guarantee the cross-process locking of a mutex. Luckily, Linux implements pread() to get around this suckiness. The problem is that only Linux implements this, so we have to keep the old locking for use on host builds with aapt and friends. aapt doesn't have this same problem of sharing file descriptors across forked processes, so we can keep the local AutoMutex to protect accesses of those files.

| * ZipFileRO: moar logging and wrap closeKenny Root2010-10-011-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | There is apparently still a race upon reading the entry Local File Header that can't be tracked down, so move the LFH check inside the mutex-protected block so we can call lseek again to see where we are when we log an error. Also, close() can fail so use TEMP_FAILURE_RETRY on it so we don't unwittingly leak file descriptors when Mean Mr. EINTR comes a-knocking. Change-Id: I753abad0bd882fe28f7281c406fa76f64393ef4c

* Looper: Drop default parameters in favor of a safer overload.Jeff Brown2010-09-161-6/+9
| | | | | | | | | | | The idea is that if you're writing code that wants fd/events/data on return from pollOnce() / pollAll() you should really pass in all of those arguments. When I changed the Looper API earlier, it was difficult to ensure that all callers were passing the right parameters since they were relying on default parameters to some degree so usage mistakes would not have been caught by the compiler.

* | Make input dispatcher only ANR for foreground windows.Jeff Brown2010-09-151-89/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brown2010-09-145-227/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brown2010-09-125-156/+513
| | | | | | | | | | | | | | | | | | | | | | | 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 the MotionEvent.FLAG_WINDOW_IS_OBSCURED flag which is set by the input manager whenever another visible window is partly or wholly obscured the target of a touch event so that applications can filter touches accordingly.

* Don't propagate StrictMode over one-way Binder calls.Brad Fitzpatrick2010-08-311-1/+5
| | | | | | | | | | | | | | | | | This was causing stack stitching problems where a one-way call with violations followed by a two-way call without violations was getting the previous one-way call's violation stack stitched on to the second caller's stack. The solution is a little more indirect than I would've liked (preserving the binder's onTransact flags until enforceInterface) but was seemingly necessary to work without changing the AIDL compiler. It should also be sufficiently cheap, since no new calls to thread-local IPCThreadState lookups were required. The additional work is just same-thread getter/setters on the existing IPCThreadState.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brown2010-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
