NSFS | CopyObject | Server Side Copy Gaps

[romayalon]

Environment info

• NooBaa Version: 5.18
• Platform: All

Actual behavior

Server side copy on NSFS doesn't support -

1. Different creation time of the source and the target.
2. Different tagging of the copy source and the target.

On GPFS we might want to consider mmclone instead of creating a hard link that shares system/extended attributes, and on POSIX we need to re-consider when to use server side copy for handling the above 2 issues.

Expected behavior

1. All points above being supported.

Steps to reproduce

1. Creation time - a. Start NooBaa NC - sudo node src/cmd/nsfs --debug=5 b. Upload an object - obj1. c. copy obj1 to obj2 -

s3api copy-object --copy-source=bucket1/obj1 --bucket bucket1 --key=obj2
{
    "CopyObjectResult": {
        "ETag": "\"mtime-d4ebts669ou8-ino-t25nk\"",
        "LastModified": "2024-09-24T07:59:41+00:00"  // now
    }
}

c. Head Object obj2 -

s3api head-object --bucket bucket1 --key=obj2
{
    "AcceptRanges": "bytes",
    "LastModified": "2024-09-24T07:13:09+00:00",  // notice the change here from the copy result - last modified of obj1
    "ContentLength": 21,
    "ETag": "\"mtime-d4ebts669ou8-ino-t25nk\"",
    "ContentType": "application/octet-stream",
    "Metadata": {}
}

d. Head Object obj1 -

s3api head-object --bucket bucket1 --key=obj1
{
    "AcceptRanges": "bytes",
    "LastModified": "2024-09-24T07:13:09+00:00",
    "ContentLength": 21,
    "ETag": "\"mtime-d4ebts669ou8-ino-t25nk\"",
    "ContentType": "application/octet-stream",
    "Metadata": {}
}

2. Tagging of a copied object (server side copy = link) - a. Start NooBaa NC - sudo node src/cmd/nsfs --debug=5 b. Upload an object - s3api put-object --bucket bucket1 --key obj-with-tagging --body obj1 c. Put object tagging - s3api put-object-tagging --bucket bucket1 --key obj-with-tagging --tagging='{"TagSet": [{ "Key": "action", "Value": "create"}]}' c. Copy object - s3api copy-object --copy-source=bucket1/obj-with-tagging --bucket bucket1 --key=obj-with-tagging-copy d. Update the tagging on the copied object -

s3api put-object-tagging  --bucket bucket1 --key=obj-with-tagging-copy --tagging='{"TagSet": [{ "Key": "action", "Value": "delete"}]}'

d. Get Object Tagging - of the copied object -

s3api get-object-tagging  --bucket bucket1 --key=obj-with-tagging-copy
{
    "TagSet": [
        {
            "Key": "action",
            "Value": "delete"
        }
    ]
}

d. Get Object Tagging - of the source object - here is the bug - we changed the tagging of the source object

s3api get-object-tagging  --bucket bucket1 --key=obj-with-tagging
{
    "TagSet": [
        {
            "Key": "action",
            "Value": "delete"
        }
    ]
}
