* Enable flattening/unflattening with custom unflatten procsGravatar msarett2016-04-22
| | | | | | | | | | | | | | | | | | Now flattenables are serialized using a string name, so that flattenables do not necessarily need to be registered before serialization. They just need to override getTypeName(). Allows custom unflatten procs to be set on the SkReadBuffer. This is optional if the flattenable is registered, but otherwise must be called.

* Fixing another clusterfuzz issueGravatar sugoi2014-06-06
| | | | | | | | | | | | | | | This was introduced by removing SkValidatingReadBuffer::readBitmap in https://codereview.chromium.org/295793002/ Since SkReadBuffer::skip wasn't virtual, it was using the unsafe SkReadBuffer::skip within SkReadBuffer::readBitmap rather than using SkValidatingReadBuffer::skip. I also removed direct uses of fReader within SkReadBuffer::readBitmap so that it can use the virtual readInt / readFixed functions that have a version in SkValidatingReadBuffer. Also, I changed SkReadBuffer::readPoint so that it uses the virtual readScalar, that way, it becomes redundant with SkValidatingReadBuffer::readPoint, which can then be removed.

* Fixing SkPicture serializationGravatar commit-bot@chromium.org2014-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a few issues while attempting to use the new serialization path for SkPicture inside a fuzzer: - SkReadBuffer and SkValidatingReadBuffer both had a fReader member instead of sharing the same member, which leads to problems if a base class function is used - In SkPicture, a header is now written as a single chunk of data, so it also has to be read as a single chunk of data - In the SkPicturePlayback destructor, a bad deserialization would lead to a crash if we don't safely unref fOpData - Also in SkPicturePlayback, if we only use a ReadBuffer for the whole deserialization, additional tags must be added to parseBufferTag() - SkValidatingReadBuffer::readBitmap() was broken, but this path wasn't usen't since the only use case for SkValidatingReadBuffer is currently image filters and bitmaps are unflattened as part of the deserialization of SkBitmapSource - SkPictureImageFilter was not deserializable.

* 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.

* 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.
