Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix [ 771097 ] frozen programs fail due to implicit import of "warnings". If the initial import of warnings fails, clear the error. When the module is actually needed, if the original import failed, see if it has managed to find its way to sys.modules yet and if so, remember it.
