df85c455c3 refactored screenshot code
the core screenshot function now can capture the screen at any lower resolution
performing bilinear filtering.

we also now have some client code to interface with the screenshot service.

it's now possible to request a screenshot at a lower resolution.

61ef747e0e Use pread() in ZipFileRO for Linux
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.

dbf6f272a2 ZipFileRO: moar logging and wrap close
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.

of a huge mmap of the file, we have to guarantee that another seek

53a415e6d1 Make input dispatcher only ANR for foreground windows.
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.

Jeff Brown
59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
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.

35b48d10bc Add logging of various important graphics events
There are 16 events logged in the event log:
SF_APP_DEQUEUE_BEFORE
SF_APP_DEQUEUE_AFTER
SF_APP_LOCK_BEFORE
SF_APP_LOCK_AFTER
SF_APP_QUEUE

SF_REPAINT
SF_COMPOSITION_COMPLETE
SF_UNLOCK_CLIENTS
SF_SWAP_BUFFERS
SF_REPAINT_DONE

SF_FB_POST_BEFORE
SF_FB_POST_AFTER
SF_FB_DEQUEUE_BEFORE
SF_FB_DEQUEUE_AFTER
SF_FB_LOCK_BEFORE
SF_FB_LOCK_AFTER

all events log the buffer conserned and a timestamp in microseconds.

by default the logging is not enabled, to turn it on:
adb shell service call SurfaceFlinger 1006 i31 1
adb shell setprop debug.graphic_log 1

The effect is immediate in SurfaceFlinger, but applications need to be
restarted.

a665ca805c Input dispatcher ANR handling enhancements.
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.

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

ZipFileRO class unhappy. Revert this for now until we can have FileMap

the APIs that had the fd to be a little more sane.

5273603e98 Don't propagate StrictMode over one-way Binder calls.
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.
