Expiry works only during runtime and is lost on shrink #112
Description
Version: v1.3.0
If I add key first without expiry and then re-set it with expiry, but the expiry is not concluded during runtime, they key is never expired and on shrinking expiry is lost. To reproduce it:
Run this code:
func main() {
db, err := buntdb.Open("data.db")
if err != nil {
log.Fatal(err)
}
defer db.Close()
err = db.Update(func(tx *buntdb.Tx) error {
_, _, err := tx.Set("my_key", "my_val", nil)
return err
})
err = db.Update(func(tx *buntdb.Tx) error {
_, _, err := tx.Set("my_key", "my_val", &buntdb.SetOptions{Expires: true, TTL: 5 * time.Second})
return err
})
}
The data.db will look like this:
*3
$3
set
$6
my_key
$6
my_val
*5
$3
set
$6
my_key
$6
my_val
$2
ae
$10

After more than 5 seconds, run this code:
func main() {
db, err := buntdb.Open("data.db")
if err != nil {
log.Fatal(err)
}
defer db.Close()
db.Shrink()
db.View(func(tx *buntdb.Tx) error {
err := tx.Ascend("", func(key, value string) bool {
fmt.Printf("key: %s, value: %s\n", key, value)
return true
})
return err
})
}
It will print:
key: my_key, value: my_val
The data.db file looks like this:
*3
$3
set
$6
my_key
$6
my_val
I guess the expiry is not set when reconstructing the state from the log if there were previous versions of the same key without expiry.
