* For non-opaque SkBitmapDevices, replace malloc-then-zero with calloc.Gravatar mtklein2015-11-05
| | | | | | | | | | | | | | | | | | | | | | There seem about a zillion possible ways to slice this. This adds and uses SkMallocPixelRef::ZeroedPRFactory. I'm not married to it. This appears to clear up a hot spot in the benchmark referenced in this bug: BUG=516426 I'm not confident enough on Windows to declare that definitively yet. It probably helps all other non-opaque layers too. Possibly significantly. So I don't forget, I profiled this: out/Release/performance_browser_tests.exe --gtest_filter=TabCapturePerformanceTest.Performance/2 --single-process No diffs: https://gold.skia.org/search2?issue=1430593007&unt=true&query=source_type%3Dgm&master=false TBR=reed@google.com Review URL: https://codereview.chromium.org/1430593007

* Refactor read and write buffers.Gravatar commit-bot@chromium.org2014-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer a step each in the hierarchy. What used to be this: SkFlattenableWriteBuffer -> SkOrderedWriteBuffer SkFlattenableReadBuffer -> SkOrderedReadBuffer SkFlattenableReadBuffer -> SkValidatingReadBuffer is now SkWriteBuffer SkReadBuffer -> SkValidatingReadBuffer Benefits: - code is simpler, names are less wordy - the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed - write buffers are completely devirtualized, important for record speed This refactoring was mostly mechanical. You aren't going to find anything interesting in files with less than 10 lines changed.

* Add a release procedure to SkMallocPixelRef; remove SkDataPixelRefGravatar halcanary@google.com2014-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This works in a way that is similar to SkData. SkMallocPixelRef::NewWithProc Motivation: Chrome has a ETC1PixelRef which calls delete[] on the pixles on destruction. There is no reason for them to almost duplicate our class, when we can provide them a more flexible class. Example use: static void delete_uint8_proc(void* ptr, void*) { delete[] static_cast<uint8_t>(ptr); } SkPixelRef* new_delete_pixref(const SkImageInfo& info, SkColorTable* ctable) { size_t rb = info.minRowBytes(); return SkMallocPixelRef::NewWithProc( info, rb, ctable, new uint8_t[info.getSafeSize(rb)], delete_uint8_proc, NULL); } SkMallocPixelRef::NewWithData Motivation: This allows up to eliminate SkDataPixelRef. We modified SkImage_Raster to use MallocPixelRef rather than SkDataPixlRef. Also: Unit tests in tests/MallocPixelRefTest.

* Fixing crash found by fuzzerGravatar commit-bot@chromium.org2013-12-30
| | | | | | | | | | | | | | | A previous fix only partially fixed this issue by adding validation on some inputs of SkImageInfo. If anything invalid is detected in SkImageInfo, unfortunately, this can cause getSafeSize() to do an illegal memory access while calling bytesPerPixel(), which could have a bad color type at this point. A possible fix is to simply make sure we are in a valid state before calling getSafeSize().

* Adding size parameter to read array functionsGravatar commit-bot@chromium.org2013-10-31
| | | | | | | | | | | | | | | | | | | 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.
