* Fix underlying issue causing crbug.com/348821.Gravatar commit-bot@chromium.org2014-03-07
| | | | | | | | | | | | | | | | SkDashPathEffect refuses to flatten itself if it thinks it's a no-op. This messes with the assumption that flattening a non-NULL effect and then unflattening from those bytes produces a non-NULL effect. I'd rather make that assumption always be true than save a few bytes for rare nonsense path effects.

* 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.

* Fixed more fuzzer issuesGravatar commit-bot@chromium.org2013-12-17
| | | | | | | | | | | | | | | | - Added the "isAvailable" function to check how much bytes are remaining in the stream before doing potentially large mallocs. That way, we can signal a bad stream instead of crashing. - Added data validation in SkImageInfo.cpp - Added NULL pointer check in displacement - Modified the fuzzer for randomized bitmap types BUG=328934,329254 R=senorblanco@google.com, senorblanco@chromium.org, reed@google.com, sugoi@google.com Author: sugoi@chromium.org Review URL: https://codereview.chromium.org/116773002 git-svn-id: http://skia.googlecode.com/svn/trunk@12723 2bbb7eff-a529-9590-31e7-b0007b416f81

* 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. Note : readPointArray and writePointArray are unused, so I could also remove them BUG= R=reed@google.com, mtklein@google.com, senorblanco@chromium.org Author: sugoi@chromium.org Review URL: https://codereview.chromium.org/37803002 git-svn-id: http://skia.googlecode.com/svn/trunk@12058 2bbb7eff-a529-9590-31e7-b0007b416f81

* Add option in flattening to write factory names inline, as we are recording.Gravatar reed@google.com2011-06-21
| | | | | | | | | | | | | | | | | | | SkGPipe needs this, since it cannot (unlike SkPicture) see all of the factories before it hands its data to the reader. In this mode, the writer embedds the factory name the first time it sees it, and then after that writes an index (referencing the fFactorySet). The reader installs an empty array, and as it encounters names, appends them to that array so that subsequent indices can be used to retrieve the previously named factory. Some of the existing patheffects did not register their factory names, so those changes are also part of this CL. Annoyingly, to register your factory using the current scheme, it has to be in the public section of the class definition. git-svn-id: http://skia.googlecode.com/svn/trunk@1663 2bbb7eff-a529-9590-31e7-b0007b416f81
