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.
Yield the connection if one has been made.
# File lib/sequel/connection_pool/single.rb, line 12 12: def all_connections 13: yield @conn if @conn 14: end
Disconnect the connection from the database.
# File lib/sequel/connection_pool/single.rb, line 17 17: def disconnect(opts=nil, &block) 18: return unless @conn 19: block ||= @disconnection_proc 20: block.call(@conn) if block 21: @conn = nil 22: end
Yield the connection to the block.
# File lib/sequel/connection_pool/single.rb, line 25 25: def hold(server=nil) 26: begin 27: yield(@conn ||= make_new(DEFAULT_SERVER)) 28: rescue Sequel::DatabaseDisconnectError 29: disconnect 30: raise 31: end 32: 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
