Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make sure elements are absolute incremental for sorted arrays when injecting. - All sorted array of DEXFile must be absolute incremental. - If injected one is the same order as one already in the array, the one in array are used to replace injected one. - All references to clone and injected one refer to ones already in array instead.
