Segregate history entries by "session" #27
Description
It would be a useful distinction to be able to page through just the command history for a single session, or for history of all sessions.
To do this we have to figure out what a "session" is:
- A random UUID generated whenever Riptide initializes. A meaningless value, but effective.
- PID + timestamp: this should be unique enough that it will differ for all logical sessions, and has the advantage of being more meaningful.
To avoid duplicate storage, we could create a new table that is basically session_history and have command_history entries hace a foreign key pointing to the originating session. We could move pid from the command entries to the session entry in this scenario assuming a session can't span multiple PIDs.
Are forks the same session, or a new one?
