93ff1f985e Fix a leak in Parcel::writeBlob.
Was mistakenly assuming that Parcel::writeFileDescriptor took
ownership of the fd that was passed in.  It does not!
Added some comments and a default parameter to allow the caller
to specify whether it wishes the Parcel to take ownership.

93ca6fb91c BlobCache: remove the mutex locking
This change removes the mutex from the BlobCache class.  The caller must
be responsible for thread synchronization in order to properly implement
the Flattenable interface, which is coming soon.  Otherwise would be the
potential for the cache contents to change between the call to the
getFlattenedSize and flatten methods.  Because the caller must do this
synchronization anyway there's no reason to also some synchronization
inside BlobCache.

3e2fb7056a Deprecate local-only CursorWindows.
There is no difference and has never really been a difference
between local-only and remotable CursorWindows.  By removing the
distinction officially in the API, we will make it easier to
implement CrossProcessCursor correctly.  CrossProcessCursor
is problematic currently because it's not clear whether a call
to getWindow() will return a local-only window or a remotable window.
As a result, the bulk cursor adaptor has special case handling
for AbstractWindowedCursors vs. ordinary CrossProcessCursors
so that it can set a remotable window before the cursor fills it.
All these problems go away if we just forget about local-only
windows being special in any way.

ec4e0063a1 Use ashmem for CursorWindows.
Bug: 5332296

The memory dealer introduces additional delays for reclaiming
the memory owned by CursorWindows because the Binder object must
be finalized.  Using ashmem instead gives CursorWindow more
direct control over the lifetime of the shared memory region.

The provider now allocates the CursorWindows and returns them
to clients with a read-only protection bit set on the ashmem
region.

Improved the encapsulation of CursorWindow.  Callers shouldn't
need to care about details like how string fields are allocated.

Removed the compile-time configuration of string and numeric
storage modes to remove some dead weight.

21230c6410 Handle orientation changes more systematically.
Bug: 4981385

Simplify the orientation changing code path in the
WindowManager.  Instead of the policy calling setRotation()
when the sensor determined orientation changes, it calls
updateRotation(), which figures everything out.  For the most
part, the rotation actually passed to setRotation() was
more or less ignored and just added confusion, particularly
when handling deferred orientation changes.

Ensure that 180 degree rotations are disallowed even when
the application specifies SCREEN_ORIENTATION_SENSOR_*.
These rotations are only enabled when docked upside-down for
some reason or when the application specifies
SCREEN_ORIENTATION_FULL_SENSOR.

Ensure that special modes like HDMI connected, lid switch,
dock and rotation lock all cause the sensor to be ignored
even when the application asks for sensor-based orientation
changes.  The sensor is not relevant in these modes because
some external factor (or the user) is determining the
preferred rotation.

Currently, applications can still override the preferred
rotation even when there are special modes in play that
might say otherwise.  We could tweak this so that some
special modes trump application choices completely
(resulting in a letter-boxed application, perhaps).
I tested this sort of tweak (not included in the patch)
and it seems to work fine, including transitions between
applications with varying orientation.

Delete dead code related to animFlags.

Handle pausing/resuming orientation changes more precisely.
Ensure that a deferred orientation change is performed when
a drag completes, even if endDragLw() is not called because the
drag was aborted before the drop happened.  We pause
the orientation change in register() and resume in unregister()
because those methods appear to always be called as needed.

73aaf0d8d2 Velocity Tracker II: The Revenge of Velocity Tracker
Bug: 5265529

Rewrote the velocity tracker to fit a polynomial curve
to pointer movements using least squares linear regression.
The velocity is simply the first derivative of this polynomial.

Clients can also obtain an Estimator that describes the
complete terms of the estimating polynomial including
the coefficient of determination which provides a measure
of the quality of the fit (confidence).

Enhanced PointerLocation to display the movement curve predicted
by the estimator in addition to the velocity vector.

By default, the algorithm computes a 2nd degree (quadratic)
polynomial based on a 100ms recent history horizon.

ecc7adef2e Input system bug fixes, particularly for stylus.
Bug: 5049148

Finished stylus support, including support for indirect stylus
and mouse tools.

Added TILT axis.  When stylus tilt X/Y is available, it is transformed
into an orientation and tilt inclination which is a more convenient
representation and a simpler extension to the exiting API.

Touch devices now only report touch data using a single input
source.  Previously touch devices in pointer mode would report
both absolute touch pad data and cooked pointer gestures.
Now we just pick one.  The touch device switches modes as needed
when the focused application enables/disables pointer gestures.
This change greatly simplifies the code and reduces the load
on the input dispatcher.

Fixed an incorrect assumption that the value of ABS_(MT_)DISTANCE
would be zero whenever the stylus was in direct contact.  It appears
that the correct way to determine whether the stylus is in direct
contact (rather than hovering) is by checking for a non-zero
reported pressure.

Added code to read the initial state of tool buttons and axis values
when the input devices are initialized or reset.  This fixes
problems where the input mapper state might have the wrong initial
state.

Moved responsibility for cancelling pending inputs (keys down,
touches, etc.) to the InputDispatcher by sending it a device reset
notification.  This frees the InputReader from having to synthesize
events during reset, which was cumbersome and somewhat brittle
to begin with.

Consolidated more of the common accumulator logic from
SingleTouchInputMapper and MultiTouchInputMapper into
TouchInputMapper.

Improved the PointerLocation output.

some other process).

29b5762efc don't return the current buffer from dequeueBuffer
we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a

Very often it was harmless, but it created a race with
updateTexImage() which could cause the following
queueBuffers() to fail.

cbe527884a fix a memory leak and memory corruption in RefBase
we would leak a weakref_impl if a RefBase was never incWeak()'ed.
there was also a dangling pointer that would cause memory corruption
and double-delete when a custom destroyer was used to delay the
execution of ~RefBase.

it turns out that the custom destroyer feature caused most of the
problems, so it's now gone. The only client was SurfaceFlinger
who now handles things on its own.

RefBase is essentially back its "gingerbread" state, but the
code was slightly cleaned-up.
