Closes#1003
**Changes Introduced:**
1. **S3 Bucket CORS Actions**
* Implemented the following S3 bucket CORS APIs:
* `PutBucketCors` – Configure CORS rules for a bucket.
* `GetBucketCors` – Retrieve the current CORS configuration for a bucket.
* `DeleteBucketCors` – Remove CORS configuration from a bucket.
2. **CORS Preflight Handling**
* Added an `OPTIONS` endpoint to handle browser preflight requests.
* The endpoint evaluates incoming requests against bucket CORS rules and returns the appropriate `Access-Control-*` headers.
3. **CORS Middleware**
* Implemented middleware that:
* Checks if a bucket has CORS configured.
* Detects the `Origin` header in the request.
* Adds the necessary `Access-Control-*` headers to the response when the request matches the bucket CORS configuration.
Implements the bucket cors s3 actions in FE to return `NotImplemented` error.
Actions implemented:
- `PutBucketCors`
- `GetBucketCors`
- `DeleteBucketCors`
`Note`: no logic is implemented for the actions in any backend and no input or output data validation is added.
Bucket ACLs are now disabled by default the same as AWS.
By default the object ownership is BucketOwnerEnforced
which means that bucket ACLs are disabled. If one attempts
to set bucket ACL the following error is returned both in
the gateway and on AWS:
ErrAclNotSupported: {
Code: "AccessControlListNotSupported",
Description: "The bucket does not allow ACLs",
HTTPStatusCode: http.StatusBadRequest,
},
ACls can be enabled with PutBucketOwnershipControls
Changed bucket canned ACL translation
New backend interface methods:
PutBucketOwnershipControls
GetBucketOwnershipControls
DeleteBucketOwnershipControls
Added these to metrics
This creates a metrics service for the rest of the gateway
that can be used to send metrics stats to any number of metrics
plugins.
To start, a statsd plugin is implemented for generic statsd
capability.
