Stanislau Hlebik 865b59eb46 mononoke: add has_copyinfo ... Summary: Motivation for this change is the following: We want to avoid doing point lookups to the db to fetch the history, and instead select the history for a file or a directory with a single select. That should be many times faster. After we select the data from filenodes table, we need to fetch copy info data. To do that we need to either do lots of point lookups to the fixedcopyinfo (which undermines the point of doing single select) or construct a giant select statement. First option is inefficient, the second can introduce big code complexity. Instead let's add a single field that says whether we have fixed copy info or not. Db size increase should be tiny. For the data that we've already imported I'm planning to run a script that will fill the has_copyinfo field correctly.
