Hello! I use the following code to dedup a file:
I use an ubuntu docker image (tar file 168M)
but get 100%
I don't know why? wrong code? or tar file is not suitable?
package main
import (
"bytes"
"io"
"io/ioutil"
"fmt"
"github.com/klauspost/dedup"
)
func main() {
data := bytes.Buffer{}
const size = 64 << 10
input,err := ioutil.ReadFile("input")
if err != nil {
panic(err)
}
w,err := dedup.NewStreamWriter(&data,dedup.ModeFixed,size,300 << 20) //300M at most
if err != nil {
panic(err)
}
inputbuff := bytes.NewBuffer(input)
io.Copy(w,inputbuff)
err = w.Close()
if err != nil {
panic(err)
}
err = ioutil.WriteFile("output", data.Bytes(), 0644)
if err != nil {
panic(err)
}
fmt.Printf("Fixed Data size:%d - %d %%\n",data.Len(),data.Len()*100/len(input))
}
