perf scripts python: exported-sql-viewer.py: Add ability to display all the database tables Displaying all the database tables can help make the database easier to understand. Committer testing: Opened all the tables, even the sqlite master table, which I selected everything and used control+C, lets see if it works... CREATE VIEW threads_view AS SELECT id,machine_id,(SELECT host_or_guest FROM machines_view WHERE id = machine_id) AS host_or_guest,process_id,pid,tid FROM threads Humm, nope, just one of the cells got copied, even with everything selected :-) Anyway, works as advertised, useful for perusing the data.
