> PutBucketLifecycleConfiguration saves a Tag filter without Key or Value as an
> empty filter that matches every key
> -----------------------------------------------------------------------------------------------------------------
>
> Key: HDDS-17703
> URL: https://issues.apache.org/jira/browse/HDDS-17703
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: S3
> Reporter: Chung-En Lee
> Assignee: Billy Shen
> Priority: Major
>
> A lifecycle rule whose {{Tag}} filter has no {{Value}}, or no {{Key}}, is
> saved with an empty filter, so the rule applies to every key in the bucket.
> AWS S3 rejects such a body with 400 MalformedXML.
> Steps to reproduce:
> # Send PutBucketLifecycleConfiguration with this rule:
> {{<Rule><ID>r1</ID><Filter><Tag><Key>a</Key></Tag></Filter><Status>Enabled</Status><Expiration><Days>1</Days></Expiration></Rule>}}
> # Send GetBucketLifecycleConfiguration.
> Actual: Step 1 returns 200. Step 2 returns the rule with {{<Filter/>}}. With
> {{ozone.lifecycle.service.enabled=true}}, KeyLifecycleService expires keys
> that don't have tag {{a}} (tested in {{TestKeyLifecycleService}}, OBS and FSO
> buckets).
> Expected: Step 1 returns 400 MalformedXML and nothing is saved, as on AWS S3.
> The same {{Tag}} inside {{<And>}} returns 500 instead, with a
> NullPointerException in the S3 Gateway log. AWS S3 returns 400 MalformedXML
> for that body too.
> The fix should ensure that:
> * A {{Tag}} without {{Key}} or {{Value}} is rejected with 400 MalformedXML,
> in {{Filter}}, and the bucket keeps its current configuration.
> * OM rejects such a filter too, because
> {{OzoneBucket#setLifecycleConfiguration}} reaches OM without going through S3
> Gateway.
> * A {{Tag}} with an empty {{Value}} is still accepted. AWS S3 accepts it.
