* fix bug where we wrote uninitialized data to the flatten stream for shaders.Gravatar reed@google.com2011-05-10
| | | | | | | | | | | | | | | | | | | Both shader and gradient_shader write matrices to the flatten stream. However, they were just calling write(&matrix, sizeof(SkMatrix)) and the matrix can contain lazily-computed function ptrs as part of its internal cache. Thus two matrices that are logically the same may write different bytes. This is a problem because picture relies on flattening objects and then using the flatten stream as a key into its cache. This matrix-write bug effectively kills the effectiveness of the cache for shaders. The fix is to write proper read/write functions for matrix (and region btw). These call through to the existing low-level flatten routines (which just write into a memory ptr). git-svn-id: http://skia.googlecode.com/svn/trunk@1290 2bbb7eff-a529-9590-31e7-b0007b416f81

* remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites withGravatar reed@google.com2011-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkSafeRef() and SkSafeUnref(). This is basically a bug waiting to happen. An optimizing compiler can remove checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on precisely this check... void SkRefCnt::safeRef() { if (this) { this->ref(); } } Since a compiler might skip the if-clause, it breaks the intention of this method, hence its removal. static inline void SkSafeRef(SkRefCnt* obj) { if (obj) { obj->ref(); } } This form is not ignored by an optimizing compile, so we use it instead. git-svn-id: http://skia.googlecode.com/svn/trunk@762 2bbb7eff-a529-9590-31e7-b0007b416f81
