we could have several thread waiting on the condition and they all need to wake-up.
also added a debug "mTid" field in the class, which contains the tid of the thread (as opposed to pthread_t), this
is useful when debugging under gdb for instance.
Rewrote SurfaceFlinger's buffer management from the ground-up.
The design now support an arbitrary number of buffers per surface, however the current implementation is limited to four. Currently only 2 buffers are used in practice.
The main new feature is to be able to dequeue all buffers at once (very important when there are only two).
A client can dequeue all buffers until there are none available, it can lock all buffers except the last one that is used for composition. The client will block then, until a new buffer is enqueued.
The current implementation requires that buffers are locked in the same order they are dequeued and enqueued in the same order they are locked. Only one buffer can be locked at a time.
eg. Allowed sequence: DQ, DQ, LOCK, Q, LOCK, Q
eg. Forbidden sequence: DQ, DQ, LOCK, LOCK, Q, Q
It turns out we were not returning the density for anything retrieved from a
TypedArray... which basically means any bitmap references from a layout or style...!!!
This is now fixed.
Also fiddle with the density compatibility mode to turn on smoothing in certain situations,
helping the look of things when they need to scale and we couldn't do the scaling at
load time.
This changes the names of the directories in aapt, to what you see
in the list of DpiTest resources. Also adds a new "long" configuration
for wide screens, which the platform sets appropriate, and introduces
a new kind of resizeability for not large but significantly larger
than normal screens which may have compatibility issues.
A small optimization to the resource code, to not re-parse the framework
resources every time we build a new AssetManager. Instead, you can now
construct a ResTable from a previously created one... of course, like the
existing code for using the data in-place, you can't delete the original
ResTable until you have deleted the one that has been constructed from it.
It turns out this was not a problem in the resource code at all. Rather,
the system process has a cache of pre-loaded attributes it uses to avoid
continually reloading things as it needs them. Well it turns out this
cache wasn't flushed after a package was uninstalled or a configuration
changed, so you could re-install an app where you change its style resources
so its theme now points to one that is inconsistent in the cache.
This is mostly a problem for developers, where they continually install
new versions of an app where resources have changed. This could possibly
show up when updating an app on a normal phone, although the problem would
eventually correct itself since this cache uses weak references.
Anyway, the cache is now reworked to be flushed appropriately.
This change also includes an update to aapt to be able to dump the
contents of bags in resources.
Applications can now declare that they support small, normal, or
large screens. Resource selection can also be done based on these
sizes. By default, pre-Donut apps are false for small and large,
and Donut or later apps are assumed to support all sizes. In either
case they can use <supports-screens> in their manifest to declare
what they actually support.
This change puts the file's access mode into the saved-state blob used by the
file backup helpers. The tests have been updated for the new blob content
format.
What this change *doesn't* do is actually backup/restore the file mode. This
change is a prerequisite for that, but mode preservation in backup/restore will
require adding metadata to the backup data stream itself, so will be approached
a bit more carefully.
(Also fixed one outright bug in the test program: ReadEntityData() had been
changed to return a ssize_t union of either a byte-count or a negative number
indicating error, but the test program was still assuming that nonzero == error,
and was spuriously failing.)
The aapt tool now reports all available densities like it already did
for locales. Also this includes more resource data output, which I
was using to examine bug #1867049 (which at this point I am unable to
reproduce).
StringArray is used in two places in framework/base and in the Sim. Ideally we should get rid of it and use Vector<String8> instead of creating new code.
- make sure that all binder Bn classes define a ctor and dtor in their respective library.
This avoids duplication of the ctor/dtor in libraries where these objects are instantiated.
This is also cleaner, should we want these ctor/dtor to do something one day.
- same change as above for some Bp classes and various other non-binder classes
- moved the definition of CHECK_INTERFACE() in IInterface.h instead of having it everywhere.
- improved the CHECK_INTERFACE() macro so it calls a single method in Parcel, instead of inlining its code everywhere
- IBinder::getInterfaceDescriptor() now returns a "const String16&" instead of String16, which saves calls to String16 and ~String16
- implemented a cache for BpBinder::getInterfaceDescriptor(), since this does an IPC. HOWEVER, this method never seems to be called.
The cache makes BpBinder bigger, so we need to figure out if we need this method at all.
- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp
- disabled copybits test, since it clashes with the new gralloc api
- Camera/Video will be fixed later when we rework the overlay apis
- made the helper Node and Iterator classes protected inner classes of List so they don't pollute the android namespace.
- use "int foo()" instead of "int foo(void)" which is more C++ stylish
- made distance() a template function, this way we write it once and it will work with combinations of iterator and const_iterator
- added the inline keyword on some function to make it clear to the compiler and the programmer that we want/intend these to be small inline functions
- added templated comparison operators to Iterator so it can compare iterator and const_iterator
- use size_t instead of "unsigned int" at places
- distance() should return a ptrdiff_t (it's kind of mening less here because it won't really work if the distance is < 0)
- made sure we handle conversions from iterator to const_iterator, but but fail at compile time in the other direction
- added operator->() on iterator and const_iterator
- made a bunch of private constructors explicit to avoid unwanted conversions

The various atomic operations are declared as inline in the header files
to cut the function call overhead. However, the plain inline keyword is
just a suggestion to the compiler which makes its own decision on whether
to inline them or not. Worst, if they are not inlined, the
-fvisibility-inlines-hidden compiler flag will render them as hidden
symbols in the object file. If they are picked up by the linker over the
ones supplied in libcutils.so the following warning will be reported:
warning: hidden symbol 'android_atomic_inc' in foo.o is referenced by
DSO bar.so
One way is to add __attribute__((visibility("default"))) to those inline
functions to suppress the linker warnings. A better way is to force
inlining as with this patch.

This change replaces the set_active_rect function with set_post_transform_crop.
There is a temporary set_active_rect function that calls
set_post_transform_crop for compatibility while commiting to multiple git
repositories.

Instead of specifying in init what to mount, and having various hacks in init
itself to deal with encryption, use a filesystem manager library to do the
work, that can also be invoked by vold when mounting an encrypted volume.
Keep all the magic filesystem info an a device specific fstab file.

This change clarifies in the ANativeWindow perform docs which perform calls are
private to the framework and should not be made by code below the HAL level.

It's up to the protocol to know when quotes are required. In the future
the response should probably all be binary blobs with lengths.

Also tid == 0 maps to gettid() on platforms that support it.
This is needed by mediaserver code that was formerly using
the old C++ API.

Add a value in audio policy flags to indicate an output
stream providing deep audio PCM buffers. Such an output
helps reducing the power consumption at the expense of audio latency.
Stagefright will indicate a preference for such an output when playing music
only (no video) and the audio duration is more than a given threshold.

Removed obsolete AUDIO_POLICY_OUTPUT_FLAG_xxx flags definition.
All project mmust use AUDIO_OUTPUT_FLAG_xxx flags from system/audio.h

Added definitions for output flags needed by new audio
HAL device API.
These flags where previously defined in audio_policy.h.
Definition in audio_policy.h remains temporarily until
all projects are changed to use new flags.

This format is exposed outside of the HAL to applications.
RAW_SENSOR is a single-channel 16-bit format, typically representing raw
Bayer-pattern images from an image sensor, with minimal processing.
The exact pixel layout of the data in the buffer is sensor-dependent, and
needs to be queried from the camera device.
Generally, not all 16 bits are used; more common values are 10 or 12
bits. All parameters to interpret the raw data (black and white points,
color space, etc) must be queried from the camera device.
This format assumes
- an even width
- an even height
- a horizontal stride multiple of 16 pixels (32 bytes).
