Fixes#1643
`GetBucketLocation` in S3 returns empty `LocationConstraint` if the bucket is in the `us-east-1` region. This fix returns empty `LocationConstraint` if the gateway region is `us-east-1`.
The debuglogger should be a top level module since we expect
all modules within the project to make use of this. If its
hidden in s3api, then contributors are less likely to make
use of this outside of s3api.
There was a change to the auth.VerifyAccess that changed
IsPublicBucket to IsPublicRequest, but another PR
(GetBucketLocation) that was merged at the same time
(and not rebased) was using the old version.
Update this to fix the build.
GetObject allows overriding response headers with the following
paramters:
response-cache-control
response-content-disposition
response-content-encoding
response-content-language
response-content-type
response-expires
This is only valid for signed (and pre-singed) requests. An error
is returned for anonymous requests if these are set.
More info on the GetObject overrides can be found in the GetObject
API reference.
This also clarifies the naming of the AccessOptions IsPublicBucket
to IsPublicRequest to indicate this is a public access request
and not just accessing a bucket that allows public access.
Fixes#1501
GetBucketLocation is being deprecated by AWS, but is still used
by some clients. We don't need any backend handlers for this since
the region is managed by the frontend. All we need is to test for
bucket existence, so we can use HeadBucket for this.
Fixes#1499
Closes#1454
Adds the implementation of [S3 GetBucketPolicyStatus action](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketPolicyStatus.html). The implementation goes to front-end. Front-End loads the bucket policy and checks if it grants public access to all users.
A bucket policy document `is public` only when `Principal` contains `*`(all users): only when it grants access to `ALL` users.
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.
Fixes#1398
The `x-amz-mp-object-size` request header can have two erroneous states: an invalid value or a negative integer. AWS returns different error descriptions for each case. This PR fixes the error description for the invalid header value case.
The invalid case can't be integration tested as SDK expects `int64` as the header value.
Closes#908
This PR introduces a new routing system integrated with Fiber. It matches each S3 action to a route using middleware utility functions (e.g., URL query match, request header match). Each S3 action is mapped to a dedicated route in the Fiber router. This functionality cannot be achieved using standard Fiber methods, as Fiber lacks the necessary tooling for such dynamic routing.
Additionally, this PR implements a generic response handler to manage responses from the backend. This abstraction helps isolate the controller from the data layer and Fiber-specific response logic.
With this approach, controller unit testing becomes simpler and more effective.
