---------------------------------
Summary: S3 ListParts with max-parts=0 or a negative value returns
HTTP 500 instead of an S3 error
Key: HDDS-17645
URL: https://issues.apache.org/jira/browse/HDDS-17645
Project: Apache Ozone
Issue Type: Bug
Components: S3
Reporter: Bablu Raul
Calling S3 {{ListParts}} with {{max-parts=0}} or a negative value (for example,
{{{}-1{}}}) returns HTTP 500 {{InternalError}} from the S3 Gateway.
The S3 Gateway passes the value to the Ozone client without validating it. The
Ozone client throws an {{IllegalArgumentException}} because {{maxParts}} must
be greater than zero. This exception is not translated into an appropriate S3
error and results in a generic HTTP 500 response.
Valid values such as {{1}} and {{1000}} work correctly.
h3. Steps to Reproduce
# Create a bucket and initiate a multipart upload.
# Upload two parts to the multipart upload.
# Verify that {{ListParts}} works with valid values:
{{A s3api list-parts --bucket "$BKT" --key "$KEY" --upload-id "$UPID"
--max-parts 1
A s3api list-parts --bucket "$BKT" --key "$KEY" --upload-id "$UPID" --max-parts
1000}}
# Call {{ListParts}} with {{{}max-parts=0{}}}:
{{A s3api list-parts --bucket "$BKT" --key "$KEY" --upload-id "$UPID"
--max-parts 0}}
# Repeat with a negative value:
{{A s3api list-parts --bucket "$BKT" --key "$KEY" --upload-id "$UPID"
--max-parts -1}}
h3. Actual Result
* {{ListParts}} works correctly with valid {{max-parts}} values.
* Requests with {{max-parts=0}} or negative values return HTTP 500.
* The client retries the request multiple times because the response is
treated as a retryable server error.
* The S3 Gateway logs show an unhandled {{{}IllegalArgumentException{}}}:
{{java.lang.IllegalArgumentException:
Max Parts Should be greater than zero}}
* The response does not contain a proper S3 XML error body.
h3. Expected Result
The S3 Gateway should validate {{max-parts}} before calling the Ozone client
and reject zero or negative values with HTTP 400 {{InvalidArgument}} and a
proper S3 XML error response.
Invalid input should not result in HTTP 500 or unnecessary client retries.
