Connect to the database. Since SQLite is a file based database, the only options available are :database (to specify the database name), and :timeout, to specify how long to wait for the database to be available if it is locked, given in milliseconds (default is 5000).
# File lib/sequel/adapters/amalgalite.rb, line 76 76: def connect(server) 77: opts = server_opts(server) 78: opts[:database] = ':memory:' if blank_object?(opts[:database]) 79: db = ::Amalgalite::Database.new(opts[:database]) 80: db.busy_handler(::Amalgalite::BusyTimeout.new(opts.fetch(:timeout, 5000)/50, 50)) 81: db.type_map = SequelTypeMap.new(self) 82: connection_pragmas.each{|s| log_yield(s){db.execute_batch(s)}} 83: db 84: end
Amalgalite is just the SQLite database without a separate SQLite installation.
