99ed22412d Use the standard CC_LIKELY and CC_UNLIKELY macros
Several source files privately defined macros LIKELY and UNLIKELY in terms
of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and
CC_UNLIKELY which are intended for this purpose.  So rename the private
uses to use the standard names.

In addition, AudioFlinger was relying on the macro expanding to extra ( ).

c4cd5301d4 Fix invalid madvise() during concurrent alloc/dealloc of MemoryDealer
Currently, madvise(MADV_REMOVE) is called after deallocation.
Another thread might allocate (and even write) the same region between
deallocation and madvise(), in which case the new thread will fail to read
what it have written.  So, call deallocate() after madvise(MADV_REMOVE).

478ae5eb5a Improve the VSYNC api a bit.
- add the ability to set the vsync delivery rate, when the rate is
set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.

- add the concept of one-shot vsync events, with a call-back
to request the next one. currently the call-back is a binder IPC.

66fbde3050 Add a basic hashtable data structure, with tests!
The basic hashtable is intended to be used to support a variety
of different datastructures such as map, set, multimap,
multiset, linkedmap, generationcache, etc.

Consequently its interface is fairly primitive.

The basic hashtable supports copy-on-write style functionality
using SharedBuffer.

The change introduces a simple generic function in TypeHelpers for
specifying hash functions.  The idea is to add template
specializations of hash_type<T> next to the relevant data structures
such as String8, String16, sp<T>, etc.

6f4cdfe0db SurfaceTexture: clean up some tests
This change cleans a few things up in the SurfaceTexture tests:
- Wraps a few long lines.
- Refactors the multithreading portions of SurfaceTextureGLToGLTest into
  a new test fixture called SurfaceTextureGLThreadToGLTest.
- Changes some of the tests that were creating their own EGLSurface to
  use the SurfaceTextureGLToGLTest fixture.
- Reorders the test functions so that they are immediately below to the
  test fixture that they use.

Mathias Agopian
a36bcd53ac attempt to fix bug 5313580
the working theory here is that a Surface object has become non-promotable
because it lost its last reference; later Surface::readFromParcel is called
the previous surface is found in the cache, but can't be promoted. this causes
a new Surface object to be created which will promptly try to connect to the
CPU_API -- this in turn will fail because the previous (now dead) surface is
still connected.

To fix this, we make sure to disconnect from the SurfaceTexture when
Surface[TextureClient] is destroyed.

aaa3ecff4b SurfaceTexture: fix a bug with buffer reallocation
This change fixes an issue involving buffer reallocation and the
ALLOW_DEQUEUE_CURRENT_BUFFER mode in SurfaceTexture.  The bug happened
when the buffer slot currently attached to the GL texture was selected
for dequeuing, but the dequeue operation caused the buffer to be
reallocated.  Because the buffer is new, the image producer could fill
the buffer and queue it before an updateTexImage call, which would
result in the "slot %d is current" error in queueBuffer.

a929748ddb SurfaceTexture: Fix to return the oldest of free buffers to Client on Dequeue call
Surface Texture dequeue logic is modified to return the oldest of the
free buffers to Client on dequeue call.

Currently dequeue method is returning the first buffer index which is free.
The parsing is done in ascending order of the buffer slot indices.
This leads to returning the buffer which has been just queued to composer,
and hence display, and this defeats the purpose of having minimum dequeue count
as 2 in asynchrnouse mode.

This is fixed by checking all the free slots and returning the oldest buffer.

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.

27a852b620 Improve the slow query instrumentation.
On user-debug and eng builds, you can set the
"db.log.slow_query_threshold" system property to queries that
take longer than the specified number of milliseconds.
Set it to 0 to log all queries.

This property has been around for a while but it was implemented
poorly.  In particular, it *changed* the behavior of the query
by calling getCount() while holding the Db connection.
In normal operation, the query will not actually run until later.

By putting the timing logic into fillWindow() instead, we ensure
that we only measure queries that actually ran.  We also capture
cases where the cursor window gets filled multiple times.

20b3da9a01 Optimize fillWindow to improve reverse-seek performance.
Bug: 5520301

When an application requests a row from a SQLiteCursor that
is not in the window, instead of filling from the requested
row position onwards, fill from a little bit ahead of the
requested row position.

This fixes a problem with applications that seek backwards
in large cursor windows.  Previously the application could
end up refilling the window every time it moved back
one position.

We try to fill about 1/3 before the requested position and
2/3 after which substantially improves scrolling responsiveness
when the list is bound to a data set that does not fit
entirely within one cursor window.

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.

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.

Made descriptor values easier to grep for and consistent with kernel
output (i.e. decimal rather than hex).  Attempt to show transaction
descriptors as such (they're in a union with a pointer).

Also, the writeLines() function in Static was using a no-op
logging call to write an iovec.  It looks like all callers are using
N=1, so I just added a log for the first string.

we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a
"FREE" buffer that was also current.
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.

8e19c2e97e fix a crasher in SurfaceTexture::updateTexImage()
we now make sure to drain the buffer queue on disconnect.
this happens only when in synchrnous mode. in async mode
we clear all buffers except the head of the queue.

for extra safety we also catch the null pointer
in updateTexImage (which should  never happen) and return
an error.

e5d6eb81e2 Read leftover parcel data when a parceled Surface is found in the cache.
This fixes an issue where the Surface readFromParcel code was leaving
unread parcel data in the case where the Surface was re-used from the
sCachedSurfaces cache. On a cache miss the code is creating a new
Surface from the remainder of the parcel data. On a hit that data was
being left unread, so anything that parcels a Surface followed by
additional arguments may end up reading the wrong values.

5873ce46ad Refactor input reader to add stylus support.
Bug: 5064702

Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher.  The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world.  The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.

Consolidated all of the InputReader locks into one simple global
Mutex.  The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher.  To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.

Added tests for new stylus features such as buttons, tool types,
and hovering.

Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.

Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN.  Oops.

Changed PointerCoords so it no longer stores useless zero
axis values.  Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.

Added dispatch of stylus hover events.

Added support for distance and tool types.

1c121f68fc SurfaceTexture: allow set_buffer_count(2)
This change relaxes an error check in SurfaceTexture::setBufferCount to
allow clients to explicitly set a buffer count of 2.  The clients that
will do this are camera and video decode.  Previously it was thought
that for those clients we would always use async mode, which requires a
minimum of 3 buffers.  However, we now believe that for some devices it
may make sense to use synchronous mode (with 2 buffers) to reduce memory
usage.
