Build or update the flights database — build_flights

Build or update the flights database for a site, normally called by screen; call if you're unable or unwilling to run screen.

Usage

build_flights_db(site, update = FALSE, refresh = FALSE, really = FALSE)

Arguments

site: Site abbreviation
update: If TRUE, update file timestamps rather than deleting newer files from database. Use this to preserve scores, comments, etc. when replacing all files.
refresh: Recreated database from scratch. Warning: this will destroy your existing database, including all assigned scores and comments. Requires also supplying really = TRUE.
really: If TRUE, allows refresh to recreate the database

Value

A list of

db: Site database table
db_name: Path and name of database table

Details

Reads any existing flights_.txt from flights directory for site, builds it or updates it for new or deleted files, saves the new version, and returns the path/name and table. Finds classes from pars.yml as case-insensitive underscore-separated words (after applying name fixes). Only flights that have not been deleted are returned.

Files with changed timestamps are presumed to have been re-downloaded with gather (as stamps are set in processing). Files shouldn't be re-downloaded and replaced unless they've changed on the source, so these files have presumable been repaired. They are refreshed in the flights database, ready for re-screening.
