This is the fastest connection pool, since it isn‘t a connection pool at all. It is just a wrapper around a single connection that uses the connection pool API.
Disconnect the connection from the database.
# File lib/sequel/connection_pool/single.rb, line 12 12: def disconnect(opts=nil, &block) 13: return unless @conn 14: block ||= @disconnection_proc 15: block.call(@conn) if block 16: @conn = nil 17: end
Yield the connection to the block.
# File lib/sequel/connection_pool/single.rb, line 20 20: def hold(server=nil) 21: begin 22: yield(@conn ||= make_new(DEFAULT_SERVER)) 23: rescue Sequel::DatabaseDisconnectError 24: disconnect 25: raise 26: end 27: end
The SingleConnectionPool always has a size of 1 if connected and 0 if not.
# File lib/sequel/connection_pool/single.rb, line 7 7: def size 8: @conn ? 1 : 0 9: end
