Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix the issue of segmentation fault when the pattern of a mbe is not setted. For Skia graphic engine, a mbe does not always have a pattern. For example, a color paint does not set a pattern on a mbe for a shape. So, we check if pattern is setted before accessing it.
