ConnPool is a thread safe connection pool for net.Conn interface. It can be used to manage and reuse connections.
This package is a fork of fatih/pool. ConnPool is a vital part of buraksezer/olric. So I need to maintain it myself.
Fixed bugs:
Install the package with:
go get github.com/buraksezer/connpool// create a factory() to be used with channel based pool
factory := func() (net.Conn, error) { return net.Dial("tcp", "127.0.0.1:4000") }
// create a new channel based pool with an initial capacity of 5 and maximum
// capacity of 30. The factory will create 5 initial connections and put it
// into the pool.
p, err := connpool.NewChannelPool(5, 30, factory)
// now you can get a connection from the pool, if there is no connection
// available it will create a new one via the factory function.
conn, err := p.Get(context.Background())
// do something with conn and put it back to the pool by closing the connection
// (this doesn't close the underlying connection instead it's putting it back
// to the pool).
conn.Close()
// close the underlying connection instead of returning it to pool
// it is useful when acceptor has already closed connection and conn.Write() returns error
if pc, ok := conn.(*connpool.PoolConn); ok {
pc.MarkUnusable()
pc.Close()
}
// close pool any time you want, this closes all the connections inside a pool
p.Close()
// currently available connections in the pool
