keyword: make restrict mode False while updating files for rollback This is a preparation for using 'repo.rollback()' instead of aborting a current running transaction for "shelve" and "unshelve". Before this patch, updating files as a part of 'repo.rollback()' overridden by keyword extension always follows 'restrict' mode of the command currently executed. "merge", "unshelve" and so on should be 'restrict'-ed, because keyword expansion may cause unexpected conflicts at merging while these commands. But, if 'repo.rollback()' is invoked while executing 'restrict'-ed commands, modified files in the working directory are marked as "CLEAN" unexpectedly by code path below: # 'lookup' below is True at updating modified files for rollback kwcmd = self.restrict and lookup # kwexpand/kwshrink : if kwcmd: self.repo.dirstate.normal(f) On the other hand, "rollback" command isn't 'restrict'-ed, because rollbacking itself doesn't imply merging. Therefore, disabling 'restrict' mode while updating files as a part of 'repo.rollback()' regardless of current 'restrict' mode should be reasonable.
