------------------------------------
Assignee: Aayush Gupta
> FSO key listing skips other matching directories when the prefix is an
> existing directory
> -----------------------------------------------------------------------------------------
>
> Key: HDDS-17413
> URL: https://issues.apache.org/jira/browse/HDDS-17413
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Manager, S3
> Reporter: Huang Kuan Hao
> Assignee: Aayush Gupta
> Priority: Major
>
> In an FSO bucket, a non-shallow key listing whose prefix is also an existing
> directory returns only that directory, and misses other directories that
> match the prefix.
> Reproduced on master at 1f9f4cc791.
> h3. Reproduction
> Create keys {{dir1bh/file1}} and {{dir1bha/file1}}, then list keys with
> prefix {{dir1bh}}:
> {noformat}
> OzoneBucket#listKeys("dir1bh", "", false)
> LEGACY: dir1bh/, dir1bh/file1, dir1bha/, dir1bha/file1
> FSO: dir1bh/, dir1bh/file1
> {noformat}
> S3 ListObjects and ListObjectsV2 without a delimiter use this listing, so on
> an FSO bucket {{list-objects-v2 --prefix dir1bh}} misses {{dir1bha/file1}}.
> Shallow listing ({{delimiter=/}}) returns {{dir1bh/}} and {{dir1bha/}} for
> both layouts.
> h3. Cause
> KeyIteratorWithFSO#getChildrenKeys calls listStatusLight with the prefix as
> keyName and allowPartialPrefixes=true. When the keyName resolves to a
> directory, OzoneListStatusHelper#listStatusFSO lists only that directory's
> children. The partial-prefix handling from HDDS-9065 covers only missing keys
> and files, so {{dir1bha/}} is never visited.
> h3. Context
> * Found while reviewing [HDDS-17308 / PR
> #11715|https://github.com/apache/ozone/pull/11715]. Its FSO tests compare
> against the listing without StartAfter because of this.
> * Not related to StartAfter.
