page already freed #72
Description
Openig same issue as boltdb/bolt#731, because coreos/bbolt also crashes in same way:
package main
import (
"log"
"math/rand"
"github.com/coreos/bbolt"
// "github.com/boltdb/bolt"
)
var BC = make(chan []byte)
func main() {
go Add(BC, "/opt/test.db")
s := make([]byte, 30)
for i := 0; i < 100000000; i++ {
rand.Read(s)
BC <- s
}
close(BC)
}
func Add(c chan []byte, bfile string) {
const bname = `bc41`
db, err := bolt.Open(bfile, 0600, nil)
if err != nil {
log.Fatal(err)
}
defer db.Close()
err = db.Update(func(tx *bolt.Tx) error {
_, err := tx.CreateBucketIfNotExists([]byte(bname))
if err != nil {
return err //fmt.Errorf("create bucket: %s", err)
}
return nil
})
if err != nil {
log.Fatal(err)
panic(err)
}
more := true
for more {
err := db.Update(func(tx *bolt.Tx) error {
b := tx.Bucket([]byte(bname))
for i := 0; i < 100000; i++ {
v := <-c
if v == nil {
more = false
return nil
}
err = b.Put(v, []byte("0"))
if err != nil {
return err
}
}
return nil
})
if err != nil {
log.Fatal(err)
panic(err)
}
}
}panic: page 3955 already freed
