Fixes#1698
`PutObjectTagging`, `GetObjectTagging` and `DeleteObjectTagging` return the `x-amz-version-id` in the response headers. The PR adds this header in the responses.
Closes#1635
Some S3 actions have dedicated bucket policy actions and require explicit policy permissions when operating on object versions. These actions were missing in the gateway: `GetObjectVersionTagging`, `PutObjectVersionTagging`, `DeleteObjectVersionTagging`, `DeleteObjectVersion`, and `GetObjectVersionAttributes`.
The logic for these actions is straightforward — if the incoming request includes the `versionId` query parameter, S3 enforces the corresponding bucket policy action that includes `version`.
This PR adds support for these missing actions in the gateway.
Fixes#1630
S3 returns `InvalidArgument: Invalid version id specified` for invalid version IDs in object-level actions that accept `versionId` as a query parameter. The `versionId` in S3 follows a specific structure, and if the input string doesn’t match this structure, the error is returned. In the gateway, the `versionId` is generated using the `ulid` package, which also has a defined structure. This PR adds validation for object-level operations that work with object versions by using the ULID parser.
These actions include: `HeadObject`, `GetObject`, `PutObjectTagging`, `GetObjectTagging`, `DeleteObjectTagging`, `PutObjectLegalHold`, `GetObjectLegalHold`, `PutObjectRetention`, `GetObjectRetention`, `DeleteObject`, `CopyObject`, `UploadPartCopy`, and `GetObjectAttributes`.
Closes#1343
Object version tagging support was previously missing in the gateway. The support is added with this PR. If versioning is not enabled at the gateway level and a user attempts to put, get, or delete object version tags, the gateway returns an `InvalidArgument`(Invalid versionId)
Fixes#1242
S3 returns a specific error for actions that expect an empty request body but receive a non-empty one. Such actions include **CopyObject** and **UploadPartCopy**, which are HTTP PUT requests with no request body. This implementation adds a check for these actions and returns the corresponding error.
Closes#1566
When an object is locked and bucket versioning is not configured at the gateway level, any object overwrite request should be rejected with an object locked error. The `PutObject` operation already follows this behavior, but `CopyObject` and `CompleteMultipartUpload` were missing this check. This change introduces the locking mechanism for `CopyObject` and `CompleteMultipartUpload` operations.
Fixes#1574
When versioning is enabled at the gateway level and object lock is enabled for a bucket, any overwrite request on a locked object should succeed since it results in the creation of a new object version. This PR fixes the logic by adding a bucket versioning status check in `CheckObjectAccess`.
Fixes#1559Fixes#1330
This PR focuses on three main changes:
1. **Fix object lock error codes and descriptions**
When an object was WORM-protected and delete/overwrite was disallowed due to object lock configurations, the gateway incorrectly returned the `s3.ErrObjectLocked` error code and description. These have now been corrected.
2. **Update `PutObjectRetention` behavior**
Previously, when an object already had a retention mode set, the gateway only allowed modifications if the mode was changed from `GOVERNANCE` to `COMPLIANCE`, and only when the user had the `s3:BypassGovernanceRetention` permission.
The logic has been updated: if the existing retention mode is the same as the one being applied, the operation is now allowed regardless of other factors.
3. **Fix error checks in integration tests (AWS SDK regression)**
Due to an AWS SDK regression, integration tests were previously limited to checking partial error descriptions. This issue seems to be resolved for some actions (though the ticket is still open: https://github.com/aws/aws-sdk-go-v2/issues/2921). Error checks have been reverted back to full description comparisons where possible.
Closes#821
**Implements conditional operations across object APIs:**
* **PutObject** and **CompleteMultipartUpload**:
Supports conditional writes with `If-Match` and `If-None-Match` headers (ETag comparisons).
Evaluation is based on an existing object with the same key in the bucket. The operation is allowed only if the preconditions are satisfied. If no object exists for the key, these headers are ignored.
* **CopyObject** and **UploadPartCopy**:
Adds conditional reads on the copy source object with the following headers:
* `x-amz-copy-source-if-match`
* `x-amz-copy-source-if-none-match`
* `x-amz-copy-source-if-modified-since`
* `x-amz-copy-source-if-unmodified-since`
The first two are ETag comparisons, while the latter two compare against the copy source’s `LastModified` timestamp.
* **AbortMultipartUpload**:
Supports the `x-amz-if-match-initiated-time` header, which is true only if the multipart upload’s initialization time matches.
* **DeleteObject**:
Adds support for:
* `If-Match` (ETag comparison)
* `x-amz-if-match-last-modified-time` (LastModified comparison)
* `x-amz-if-match-size` (object size comparison)
Additionally, this PR updates precondition date parsing logic to support both **RFC1123** and **RFC3339** formats. Dates set in the future are ignored, matching AWS S3 behavior.
Closes#1518
Adds the `x-amz-object-size` header to the `PutObject` response, indicating the size of the uploaded object. This change is applied to the POSIX, Azure, and S3 proxy backends.
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.
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
Fixes#1345
The previous implementation incorrectly parsed the `x-amz-sdk-checksum-algorithm` header for the `CompleteMultipartUpload` operation, even though this header is not expected and should be ignored. It also mistakenly treated the `x-amz-checksum-algorithm` header as an invalid value for `x-amz-checksum-x`.
The updated implementation only parses the `x-amz-sdk-checksum-algorithm` header for `PutObject` and `UploadPart` operations. Additionally, `x-amz-checksum-algorithm` and `x-amz-checksum-type` headers are now correctly ignored when parsing the precalculated checksum headers (`x-amz-checksum-x`).
Fixes#1388Fixes#1389Fixes#1390Fixes#1401
Adds the `x-amz-copy-source` header validation for `CopyObject` and `UploadPartCopy` in front-end.
The error:
```
ErrInvalidCopySource: {
Code: "InvalidArgument",
Description: "Copy Source must mention the source bucket and key: sourcebucket/sourcekey.",
HTTPStatusCode: http.StatusBadRequest,
},
```
is now deprecated.
The conditional read/write headers validation in `CopyObject` should come with #821 and #822.
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.
Fixes#1036
Fixes the issue when calling a non-existing root endpoint(POST /) the gateway returns `NoSuchBucket`. Now it returns the correct `MethodNotAllowed` error.
