Hi RGW team,

Nautilus 14.2.11.
I can apply next rule:

aws s3api get-bucket-lifecycle-configuration --bucket test-cc45ce9b-43c8-4e28-8a9a-a9d3ad0a2652

{
    "Rules": [
        {
            "Status": "Enabled",
            "Prefix": "",
            "Expiration": {
                "Days": 0
            },
            "ID": "remove old objects" 
        }
    ]
}

But in AWS s3:

aws s3api put-bucket-lifecycle-configuration --lifecycle-configuration  file://~/ownCloud/ownCloud-tmp/s3-example/lc_by_days.json --bucket test-fatruden

An error occurred (InvalidArgument) when calling the PutBucketLifecycleConfiguration operation: 'Days' for Expiration action must be a positive integer

In Luminous 12.2.12 we couldn't apply this rule. Validation worked fine on Luminous.

I think it was changed in this issue: https://tracker.ceph.com/issues/38389

But it's not correct.

There are two type of lifecycle rules:
1. Expiration rules (removing objects)
2. Transition rules (moving objects to another storage class)

For Expiration rules AWS s3 doesn't allow Days=0, for Transition rules it's possible to specify Days=0.

You can read about it in https://docs.aws.amazon.com/AmazonS3/latest/dev/lifecycle-configuration-examples.html
And you can reproduce it with AWS S3 and awscli.
