Fixes#1767Fixes#1773
As object ACLs are not supported in the gateway, any attempt to set an ACL during object creation must return a NotImplemented error. A check has now been added to `PutObject`, `CopyObject`, and `CreateMultipartUpload` to detect any ACL-related headers and return a NotImplemented error accordingly.
Fixes#1751
When an object lock–related operation is performed on an object in a bucket where Object Lock is not enabled, an `InvalidRequest` error is returned; however, the error message differs for some actions. This PR introduces a new error, `ErrMissingObjectLockConfigurationNoSpaces`, for `PutObject`, `CopyObject`, and `CreateMultipartUpload` to maintain compatibility with S3 in terms of the error message. It also adds the missing integration tests for these actions.
Fixes#1733Fixes#1734
The `x-amz-object-lock-retain-until-date` request header appears in the `PutObject`, `CopyObject`, and `CreateMultipartUpload` operations. This PR fixes the two types of error codes and messages returned when the header value is invalid or expired and adds the corresponding integration tests.
Fixes#1708
This PR focuses on evaluating the `x-amz-if-none-match` precondition header for object PUT operations. If any value other than `*` is provided, a `NotImplemented` error is returned. If `If-Match` is used together with `If-None-Match`, regardless of the value combination, a `NotImplemented` error is returned. When only `If-None-Match: *` is specified, a `PreconditionFailed` error is returned if the object already exists in `PutObject` or `CompleteMultipartUpload`; if the object does not exist, object creation is allowed.
Fixes#1709
If any precondition header is present(`If-Match`, `If-None-Match`) in `PutObject` and `CompleteMultipartUpload` and there's no object in the bucket with the given key, a `NoSuchKey` error is now returned. Previously the headers were simply ignored and new object creation was allowed.
Fixes#1710
The `If-Match` and `If-None-Match` precondition header values represent object ETags. ETags are generally quoted; however, S3 evaluates precondition headers equivalently whether the ETag is quoted or not, comparing only the underlying value and ignoring the quotes if present.
The new implementation trims quotes from the ETag in both the input precondition header and the object metadata, ensuring that comparisons are performed purely on the ETag value and are insensitive to quoting.
All the integration tests used to be in a single file, which had become large, messy, and difficult to maintain. These changes split `tests.go` into multiple files, organized by logical test groups.
