Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix issue of missed function for unittest. If we make for unittest, it will be failed for missed functions. Since we change name of functions to avoid type conflict, ld can not find the functions with original names. So, we make dummy functions to resolve it. We had better decouple them to avoid this problem.
