A go net.conn pool for Golang. Inspired by the Pool(fatih/pool), add some code and function for limit the active connection numbers.
go get github.com/dubin555/goConnectPoolPlease make sure you use the master branch code.
// a factory func to generate a net connection.
factory := func() (net.Conn, error) { return net.Dial("tcp", "127.0.0.1:9999") }
// create a new channel based pool with an initial capacity of 5, maximum capacity of 30,
// and maximum actives of 15.
pool, err := pool.NewChannelPool(5, 30, 15, factory)
// get a connection from the pool, non blocking mode, if reach the limit, return nil instead.
// Block Mode
conn, err := pool.Get()
// balabalabala
// close the conn, will release the conn to the pool by calling Close()
conn.Close()
// Non Blocking Mode, will return nil when no permission
conn, err := pool.TryGet()
// close the pool
pool.Close()
// return the connections length
p.Len()
// return the current active permissions
p.LenActives()
