HDDS-12869. Add some corner cases in create bucket

[rajeshkumarchandolu]

What changes were proposed in this pull request?

This change extends the S3 gateway smoketest coverage for create-bucket behavior aligned with AWS naming rules and related error responses.

What and why

HDDS-12869 adds Robot tests for create-bucket corner cases: invalid bucket names (length, character set, uppercase, leading/trailing punctuation, IP-shaped names, adjacent periods, all-numeric names) and validation that duplicate create returns the expected error when the requester already owns the bucket. The S3 gateway already returns the appropriate error codes; this PR adds smoketest coverage so regressions are caught in compose/CI.

Changes

In hadoop-ozone/dist/src/main/smoketest/s3/bucketcreate.robot, the following test cases are added or updated:

• Name too short (ab) → InvalidBucketName
• Name too long (64 characters) → InvalidBucketName
• All-uppercase bucket name → InvalidBucketName
• Mixed-uppercase bucket name → InvalidBucketName
• Invalid characters (test#12-$) → error message contains Invalid bucket name (AWS CLI client validation)
• Trailing hyphen on otherwise valid name → InvalidBucketName
• Two adjacent periods → InvalidBucketName
• IP-address-shaped name → InvalidBucketName
• Leading dash (--bucket=-test) → InvalidBucketName
• Leading period → InvalidBucketName
• Trailing period → InvalidBucketName
• All-numeric name → InvalidBucketName
• Maximum valid length (63 characters) → success

Duplicate create with the same name and the same credentials is unchanged; it remains covered by the existing Create bucket which already exists test, which expects BucketAlreadyOwnedByYou.

The 63-character success case uses a unique 63-character name (b plus 62 random lowercase characters) so repeated runs on the same compose cluster do not fail with BucketAlreadyOwnedByYou on a fixed bucket name.

Pre-existing cases in the same file (Create new bucket, default group ACL, web-endpoint-style bucket names, bucket ownership verification) are unchanged and still run as part of the suite.

No S3 gateway or OM code changes are included.

How was this patch tested?

Manual smoketest on the docker-compose ozone environment:

1. Build dist smoketest artifacts:
   mvn clean install -DskipTests -f hadoop-ozone/dist/pom.xml

2. From hadoop-ozone/dist/target/ozone-*-SNAPSHOT/compose/ozone, start compose (recreate containers after a dist rebuild if needed):
   docker compose up -d

3. Run the robot suite:
   ../test-single.sh s3g s3/bucketcreate.robot

   Note: Test buckets named like web endpoints uses fixed bucket names (conf, jmx, …). On a cluster where those buckets already exist from a prior run, delete them or recreate the compose environment before re-running the suite.

Result: 19 tests, 19 passed, 0 failed.

We could also add some more cases like names with:

• Leading dash
• Leading period
• Trailing period
• All numeric

[rajeshkumarchandolu]

@sreejasahithi can you validate now . i had added all the scenarios mentioned

[Gargi-jais11]

Thanks @rajeshkumarchandolu for adding robot tests.
+1 to @sreejasahithi comment.
Please check this aws documentation for naming rules and add one robot test for each rules which are currently supported by ozone. This was we can verify each of the rules are satisfied.
