blob/fileblob: bucket.List is not working for /tmp folder

[ducquangkstn]

Describe the bug

• blob/fileblob: bucket.List is not working for /tmp folder

To Reproduce

• echo "aaa" > /tmp/report.txt
• run the

bucket, err := fileblob.OpenBucket("/tmp", nil)
if err != nil {
  panic(err)
}
it := bucket.List(&blob.ListOptions{Prefix: "report.txt"})
for {
  obj, err := it.Next(context.TODO())
  if err == io.EOF {
     break
  } else if err != nil {

  }
  fmt.Println(obj.Key)
}

Expected behavior

• It should printout report.txt

Version

0.33.0

Additional context

I am using Mac OS

That exact thing works for me on Linux, and the unit tests should cover this as well (and run on MacOS).

Can you try again without the Prefix option and see what it prints? Does it work in a different directory other than /tmp?

You're going to have to help me debug this since I can't reproduce it.

I'm not sure why but changing /tmp to /private/tmp fixes the issue on MacOS

What happens if you do

$ cd /tmp
$ pwd
$ ls

in a terminal on your MacOS? And same for /private/tmp.

It looks like /tmp might be a symbolic link on MacOS; os.WalkDir does not follow symbolic links:
