The GCC compilers for Android and Ubuntu do not seem to be able to
inline the memcmp operations on GrBinHashKey data. Write the comparisons
manually. Also shortcut GrBinHashKey::EQ to skip comparison when hashes
do not match.
Speeds up grresourcecache_find test on ARM and x86_64. Speeds up
grresourcecache_add on x86_64.
In order to test the change, moves ad hoc Gr unit tests from
src/gr_unittest.cpp to tests/GrUnitTests to be consistent with other
tests and enables GrUnitTests.
Fixes a regression from r2863 with where re-setting GrBinHashKey data
would not set the hash correctly. This should also improve the hash
function itself. The regression caused many of the hash operations be
no-ops. This is caught by the unit test.
Renames the comparison functions that GrHashTable needs from EQ, LT to
Equals, LessThan.
Renames GrTBinHashKey to GrBinHashKey. The GrTBinHashKey used to
forward comparison functions to an ENTRY template class, which would
extract the key and call back to the GrTBinHashKey. This would save
the user from writing one comparison function when comparison was done
with int ENTRY::compare(). There's no real benefit in this now. Also
this was used only for one class (GrTextureStripAtlas). The other use
in GrResourceKey was not actually using the provided "shortcut". The
new GrBinHashKey is not templated with the entry, rather just provides
== and < functions. The users of GrTHashTable provide the needed
functions now.
Adds explicit documentation of functions that are actually needed
GrTHashTable for the Key template. Adds SK_DEBUG guards according to
the contract.

Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test
GrResourceCache::add and GrResourceCache::find. The tests work only
with GPU backends, since GrResourceCache needs an GrGpu.
Modifies bench tests to override SkBenchmark::isSuitableFor(Backend)
function that specifies what kind of backend the test is inteded
for. This replaces the previous "fIsRendering" flag that would
indicate test that did no rendering.
Adds SkCanvas::getGrContext() call to get the GrContext that the
canvas ends up drawing to. The member function solves a common
use-case that is also used in the benchmark added here.

SkTDStackNester is a class used by PdfViewer to assist in saving
and restoring the PDF state. Clean up and test this class.
Add some documentation.
Add FIXME's where I have questions to resolve.
Fix a bug where fNestingLevel was not initialized.
Remove a commented out line of code copied over from
SkTDStack.
Rename SkTDStackNester::nests() to nestingLevel() and make it const.
Remove unnecessary predeclaration and friend declaration.
Remove index() (both const and non-const versions). They were
unused, return something that may not be expected (index from
the top, rather than from the bottom), and don't work to get any
elements in earlier Recs once the first one is full.
Report a warning if the nesting level goes above the maximum level,

Mostly superficial changes, to help me make sure I understand the

SkPdfRenderer:
First class I'm modifying. Move it into include/ and src/ directories.
Inherit from SkNoncopyable.
Replace load() with factory function which returns NULL if the load
fails.
Remove unload() and loaded(), which no longer make sense, since the
factory will return NULL on a failure to load, and unload() happens
on destruction.
Use a const char* for loading a PDF, following the convention of
SkStream::NewFromFile.
Remove unnecessary call to sqrt in SkPDFNativeRenderToBitmap.
Also in SkPDFNativeRenderToBitmap, use an appropriate SkScalar macro
to convert to an integer.

SK_CONF_TRY_SET() is like SK_CONF_SET(), but doesn't complain if
confname can't be found. This is useful if the SK_CONF_DECLARE is
inside a source file whose linkage is dependent on the system.
Internally to the SkRTConf system, SkRTConfRegistry::set() was given
an additional parameter controling wanrings.
A new RuntimeConfig unit test was introduced. It should run silently.
In the future, it should be expanded to cover all of the SkRTConf
functionality.
(For example, the images.jpeg.suppressDecoderWarnings variable is
defined and used only in SkImageDecoder_libjpeg.cpp, but on MacOS, we
use Core Graphics via SkImageDecoder_CG.cpp - SkImageDecoder_libjpeg
is never linked in. The same is true of the Windows Imaging Component

The reason for this CL is to allow greater decoder flexibility.
Chrome currently uses its own decoding functions. These allow for
greater flexibility in dealing with images with multiple frames or
partial data. The DecodeProc function was not flexible enough to
handle these. Instead of asking the decoder to squeeze everything
into the DecodeProc, we now ask the downstream library to inherit from
SkCachingPixelRef. If WebKit's LazyDecodingPixelRef is re-tooled to
inherit from SkCachingPixelRef, then it can make use of Skia's caching
ability while still allowing it to deal with multiple frames, scaling,
subsetting, and partial data.
- The abstract SkCachingPixelRef class handles caching the decoded
data in a SkScaledImageCache. This class relies on the virtual
functions onDecodeInfo() and onDecode() to do the actual decoding
of data.
- The SkLazyCachingPixelRef class is derived from SkCachingPixelRef.
It provides an implementation of onDecodeInfo() and onDecode() in
terms of calls to a SkBitmapFactory::DecodeProc function. It also
provides an Install() static method which installs a new
SkLazyCachingPixelRef into a SkBitmap.
SkLazyCachingPixelRef exists for two reasons: to test
SkCachingPixelRef within Skia and as an example for downstream
developers to make their own classes that inherit from
SkCachingPixelRef.
- The CachedDecodingPixelRefTest was updated to test the
SkLazyCachingPixelRef class and indirectly the SkCachingPixelRef
class.

In some cases, the allocated array into which the data will be read is using getArrayCount() to allocate itself, which should be safe, but some cases use fixed length arrays or compute the array size before reading, which could overflow if the stream is compromised.
To prevent that from happening, I added a check that will verify that the number of bytes to read will not exceed the capacity of the input buffer argument passed to all the read...Array() functions.
I chose to use the byte array for this initial version, so that "size" represents the same value across all read...Array() functions, but I could also use the element count, if it is preferred.
Note : readPointArray and writePointArray are unused, so I could also remove them

This adds an invalidation listener mechanism to SkPixelRef to let it send this message while still staying ignorant of who's listening.
These messages are tricky to deliver. The SkPixelRefs they originates from and the GrResourceCaches they ultimately end up at may be on different threads; neither class is threadsafe; their object lifetimes are totally independent; it's a many-senders-to-many-receivers relation; and neither codebase should really know about the other.
So I've added a per-message-type global message bus to broadcast messages to threadsafe inboxes. Anyone can post() a message, which will show up in all the inboxes of that type, read whenever the inbox's owner calls poll(). The implementation is _dumb_; it can be improved in several dimensions (inbox size limits, lock-free message delivery) if we find the need.
I took some care to make sure not to send the invalidation message for any SkPixelRef that's sharing a generation ID with another SkPixelRef.

Adds GrEffect::willUseInputColor() which indicates whether or not the
input color affects the output of the effect. This is needed for
certain Xfermodes, such as kSrc_Mode. For these modes the color filter
will not use the input color.
An effect with GrEffect::willUseInputColor() true will cause all color
or coverage effects before it to be discarded, as their computations
cannot affect the output. In these cases program is marked as having
white input color.
This fixes an assert when Skia is compiled in a mode that prefers
using uniforms instead of attributes for constants. (Flags
GR_GL_USE_NV_PATH_RENDERING or GR_GL_NO_CONSTANT_ATTRIBUTES). Using
attributes hides the problem where the fragment shader does not need
input color for color filters that ignore DST part of the filter. The
assert would be hit when uniform manager tries to bind an uniform which
has been optimized away by the shader compiler.
Adds specific GrGLSLExpr4 and GrGLSLExpr1 classes. This way the GLSL
expressions like "(v - src.a)" can remain somewhat readable in form of
"(v - src.a())". The GrGLSLExpr<typename> template implements the
generic functionality, GrGLSLExprX is the specialization that exposes
the type-safe interface to this functionality.
Also adds operators so that GLSL binary operators of the form
"(float * vecX)" can be expressed in C++. Before only the equivalent
"(vecX * float)" was possible. This reverts the common blending
calculations to more conventional order, such as "(1-a) * c" instead of
"c * (1-a)".
Changes GrGLSLExpr1::OnesStr from 1 to 1.0 in order to preserve the
color filter blending formula string the same (with the exception of
variable name change).
Shaders change in case of input color being needed:
- vec4 filteredColor;
- filteredColor = (((1.0 - uFilterColor.a) * output_Stage0) + uFilterColor);
- fsColorOut = filteredColor;
+ vec4 output_Stage1;
+ { // Stage 1: ModeColorFilterEffect
+ output_Stage1 = (((1.0 - uFilterColor_Stage1.a) * output_Stage0) + uFilterColor_Stage1);
+ }
+ fsColorOut = output_Stage1;
Shaders change in case of input color being not needed:
-uniform vec4 uFilterColor;
-in vec4 vColor;
+uniform vec4 uFilterColor_Stage0;
out vec4 fsColorOut;
void main() {
- vec4 filteredColor;
- filteredColor = uFilterColor;
- fsColorOut = filteredColor;
+ vec4 output_Stage0;
+ { // Stage 0: ModeColorFilterEffect
+ output_Stage0 = uFilterColor_Stage0;
+ }
+ fsColorOut = output_Stage0;

This change removes sk_stdint.h since it is only needed for vs2008 and earlier.
This change removes SK_MMAP_SUPPORT define since it is no longer used.
This change removes the stdio.h include from SkTypes.h since on many systems
this is a very large header, few Skia files actually use it, it is
available everywhere standard, and SkDebugf should be used instead.
After this change there is no need for external users to put Skia's

Add new runtime configuration variable,
images.gif.suppressDecoderWarnings, which suppresses warning and
errors from the GIF library. It defaults to "true", which is current
behavior.
(This setting can be changed by setting the environment variable
skia_images_gif_suppressDecoderWarnings="false".)
Some conditions which were errors before are now warnings:
- If the image width or height is greater than the GIF screen width or
height (respectively) we expand the screen to hold the image.
- If the offset of the image inside the screen would place the
image outside of the screen, we shift the image to fix this.
- If the image lacks a color table, we create a default color table.
- If the image is truncated, then the rest of the image is filled with
the fill color.
In all four cases, if images.gif.suppressDecoderWarnings is set to
false, then a warning message is printed via SkDebugf.
In the event of another kind of error, SkGIFImageDecoder::onDecode()
will still return false. But with this change, if
images.gif.suppressDecoderWarnings is set to false, a description of
the error is printed via SkDebugf.
Also, added a new unit test GifTest, which tests the deconing of both
good GIf files and corrupted files that should now work with this
change. This unit test is disabled on Win32, iOS, and Mac.

This change address what happens when a jpeg is partially downloaded
before failing. Many browsers will render it anyway: we want Skia to
do the same. The JpegTest takes a perfectly cromulent jpeg file and
only passes into the ImageDecoder the first half of the image. We
then verify that the image decoder returns a valid bitmap of the
correct dimensions.
We also fixed some png library errors, including issue 1691.
Also, suppressed the majority of warnings from using libpng and
libjpeg. By default, most warnings are *not* suppressed in debug mode.
If you have a debug binary and wish to suppress warnings, set the
following environment variables to true
skia_images_png_suppressDecoderWarnings
skia_images_jpeg_suppressDecoderWarnings
or from within a program that links to Skia:
#if defined(SK_DEBUG)
#include "SkRTConf.h"
SK_CONF_SET("images.jpeg.suppressDecoderWarnings", true);
SK_CONF_SET("images.png.suppressDecoderWarnings", true);
#endif
I tested this, before (control) and after these changes (test), on
364,295 skps from the cluster telemetry.
- number of errors+warnings in control = 2804
- number of errors+warnings fixed = 2283
- number of PNG verbosity fixed = 2152
- number of PNG error fixed = 4
- number of PNG segfault fixed = 3
- number of PNG errors changed to warnings = 62
- number of JPG verbosity fixed = 26
- number of JPG error fixed = 91
Not all errors and warning have been fixed.
These numbers were generated using the find_bad_images_in_skps.py
program. This program may be useful going forward for testing
image-decoding libraries on skp files from the cluster telemetry.
find_bad_images_in_skps.py depends on the test_image_decoder program,
which simply executes the SkImageDecoder::DecodeFile function and uses
its exit status to report success or failure.

- TileImageFilter -> SkTileImageFilter
- OffsetImageFilter -> SkOffsetImageFilter (already existed)
- FloodImageFilter -> SkFloodImageFilter
- CompositeImageFilter -> SkCompositeImageFilter
All functions were copied as is, without modification (except for warnings fixes), except for the offset filter, which was merged into the existing SkOffsetImageFilter class, as a special case when a crop rect is provided. Since the names won't clash with the names in blink, it should be easy to integrate them in blink later and fix issues, if needed.
