Integrate x-amz-website-redirect-location across object metadata flows so uploads, copies, multipart creation, HEAD, and GET preserve and return redirect locations, and website hosting applies object-level redirects from the stored value.
Enhances the static website hosting implementation with more complete S3-compatible behavior across request handling, backend storage, validation, CORS, and errors.
Adds dedicated website endpoint handling for GET, HEAD, and OPTIONS requests, including index document resolution, error document serving, redirect-all support, pre-fetch and post-error routing rules, query string preservation in redirects, public access checks before object reads, and method-not-allowed responses.
Improves error handling for website responses by returning S3-compatible HTML error bodies with request IDs, host IDs, x-amz-error-code, x-amz-error-message, and specialized error fields. This also fixes website-related validation errors to return more accurate S3-style error codes and messages, including invalid redirect protocols, invalid HTTP redirect/error codes, conflicting routing rule replacements, routing rule limits, and oversized website configuration requests.
Adds website CORS support for GET, HEAD, and OPTIONS preflight requests, including bucket CORS lookup through website host bucket resolution, allowed origin/method/header validation, exposed header handling, ETag exposure, Vary headers, max-age handling, and CORS access-denied responses.
Adds debug logging around website configuration parsing, validation failures, CORS checks, backend lookup failures, and internal website error paths to make failures easier to diagnose.
Adds compressed website configuration storage so larger configs fit backend metadata limits, including gzip storage for POSIX extended attributes and base64-encoded compressed metadata for Azure. Also adds Azure PutBucketWebsite, GetBucketWebsite, and DeleteBucketWebsite support.
Adds and expands test coverage for website config validation, S3-compatible HTML error bodies, website routing behavior, public access enforcement, HEAD behavior, CORS handling, PutBucketWebsite limits, and end-to-end website hosting through a Docker-based dnsmasq test setup and CI workflow.

Refactor global S3 error handling around structured error types and centralized XML response generation.
All S3 errors now share the common APIError base for the fields every error has: Code, HTTP status code, and Message. Non-traditional errors that need AWS-compatible XML fields now have dedicated typed errors in the s3err package. Each typed error implements the shared S3Error behavior so controllers and middleware can handle errors consistently while still emitting error-specific XML fields.
Add a dedicated InvalidArgumentError type because InvalidArgument is used widely across request validation, auth, copy source handling, object lock validation, multipart validation, and header parsing. The new InvalidArgument path uses explicit InvalidArgErrorCode constants with predefined descriptions and ArgumentName values, keeping call sites readable while preserving the correct InvalidArgument XML shape and optional ArgumentValue.
New structured errors added in s3err:
- `AccessForbiddenError`: Method, ResourceType
- `BadDigestError`: CalculatedDigest, ExpectedDigest
- `BucketError`: BucketName
- `ContentSHA256MismatchError`: ClientComputedContentSHA256, S3ComputedContentSHA256
- `EntityTooLargeError`: ProposedSize, MaxSizeAllowed
- `EntityTooSmallError`: ProposedSize, MinSizeAllowed
- `ExpiredPresignedURLError`: ServerTime, XAmzExpires, Expires
- `InvalidAccessKeyIdError`: AWSAccessKeyId
- `InvalidArgumentError`: Description, ArgumentName, ArgumentValue
- `InvalidChunkSizeError`: Chunk, BadChunkSize
- `InvalidDigestError`: ContentMD5
- `InvalidLocationConstraintError`: LocationConstraint
- `InvalidPartError`: UploadId, PartNumber, ETag
- `InvalidRangeError`: RangeRequested, ActualObjectSize
- `InvalidTagError`: TagKey, TagValue
- `KeyTooLongError`: Size, MaxSizeAllowed
- `MetadataTooLargeError`: Size, MaxSizeAllowed
- `MethodNotAllowedError`: Method, ResourceType, AllowedMethods
- `NoSuchUploadError`: UploadId
- `NoSuchVersionError`: Key, VersionId
- `NotImplementedError`: Header, AdditionalMessage
- `PreconditionFailedError`: Condition
- `RequestTimeTooSkewedError`: RequestTime, ServerTime, MaxAllowedSkewMilliseconds
- `SignatureDoesNotMatchError`: AWSAccessKeyId, StringToSign, SignatureProvided, StringToSignBytes, CanonicalRequest, CanonicalRequestBytes
Fix CompleteMultipartUpload validation in the Azure backend so missing or empty `ETag` values return the appropriate S3 error instead of allowing a gateway panic.
Fix presigned authentication expiration validation to compare server time in `UTC`, matching the `UTC` timestamp used by presigned URL signing.
Add request ID and host ID support across S3 requests. Each request now receives AWS S3-like identifiers, returned in response headers as `x-amz-request-id` and `x-amz-id-2` and included in all XML error responses as RequestId and HostId. The generated ID structure is designed to resemble AWS S3 request IDs and host IDs.
The request signature calculation/validation for streaming uploads was previously delayed until the request body was fully read, both for Authorization header authentication and presigned URLs.
Now, the signature is validated immediately in the authorization middlewares without reading the request body, since the signature calculation itself does not depend on the request body. Instead, only the `x-amz-content-sha256` SHA-256 hash calculation is delayed.
Store multipart upload metadata through shared backend helpers so POSIX and Azure use the same encode/decode path. POSIX stores raw gzipped JSON in metadata stores, while Azure stores base64-encoded gzip for string metadata. Retrieval falls back to the legacy raw JSON format for existing objects. Storing the mp metadata compressed in posix will guarantee that for any allowed number of parts, the metadata won't exceed the xattr threshold(64KB).
Fixes#2052Fixes#2056Fixes#2057
Previously, GetObject and HeadObject used the request's `Range` header to determine the response status code, which caused incorrect 206 responses for invalid Range header values.
The status is now driven by whether res.ContentRange is set in the response, rather than by the presence of a range in the request. Backends (posix and azure) now set Content-Range for PartNumber=1 on non-multipart objects, skipping zero-size objects where no range applies.
HeadObject was also fixed to return 206 when Content-Range is present, and to only return checksums when the full object is requested.
Closes#1064
Use the multipart ETag as the in-progress directory suffix instead of the static `.inprogress` marker so that concurrent CompleteMultipartUpload calls for the same upload ID are all treated as successful (idempotent) rather than racing, where only one succeeded and the rest returned NoSuchUpload.
After finalizing the multipart upload, store an `mp-metadata` xattr on the assembled object that records the upload ID and cumulative byte offsets for each part. GetObject and HeadObject now use this metadata to serve individual part ranges via the `partNumber` query parameter, returning a successful response instead of returning NotImplemented.
Add two new S3 error codes:
- `ErrInvalidPartNumberRange` (416 RequestedRangeNotSatisfiable) — returned
when the requested part number exceeds the number of parts in the upload.
- `ErrRangeAndPartNumber` (400 BadRequest) — returned when both a Range header
and a partNumber query parameter are specified on the same request.
As multipart uploads are translated to blobs in azure blob storage, they were visible in ListObjects(V2) as complete objects. Now the blobs with multipart prefix are filtered out during listing.
The listing logic is rewritten client-side to implement proper S3 semantics: flat blob enumeration with manual delimiter handling, correct truncation (IsTruncated only set when more items genuinely exist beyond maxKeys), and StartAfter/Marker/ContinuationToken applied via the lexicographic max of both constraints in ListObjectsV2.
For the same reason bucket deletion was not allowed. Now multipart objects are explicitly checked on bucket deletion and any pending multipart upload doesn't block the bucket deletion anymore.
Closes#1897
Extract the `X-Amz-Source-Expected-Bucket-Owner` header for CopyObject and UploadPartCopy. Verify the source bucket owner in the backend and if the provided access key id doesn't match, return an `AccessDenied` error.
Fixes#1896
Enforces the S3 `5 GiB` copy source size limit across the posix and azure
backends for `CopyObject` and `UploadPartCopy`, returning `InvalidRequest` when
the source object exceeds the threshold.
The limit is now configurable via `--copy-object-threshold`
(`VGW_COPY_OBJECT_THRESHOLD`, default 5 GiB).
A new `--mp-max-parts flag` (`VGW_MP_MAX_PARTS`, default `10000`) has been added to make multipart upload parts number limit configurable.
No integration test has been added, as GitHub Actions cannot reliably
handle large objects.
When copying between two different Azure blobs, the source download
stream body was only consumed by PutObject but never explicitly closed.
If PutObject or any subsequent step returned an error, the underlying
HTTP connection held by the Azure SDK was never released, leaking both
the connection and any internal SDK retry goroutines attached to it.
Added a deferred close on downloadResp.Body immediately after the
successful DownloadStream call to ensure the body is always drained and
released regardless of the outcome.
Azure's ListContainers Marker parameter requires an opaque internal token
(e.g. /accountname/containername) rather than a plain container name, so
passing MaxResults and our ContinuationToken directly to the Azure API
caused 400 OutOfRangeInput errors. Rework ListBuckets to iterate all Azure
pages client-side, skip entries at or before the ContinuationToken (matching
the posix backend's "start after" semantics), and stop once MaxBuckets items
have been collected, setting ContinuationToken to the last returned bucket
name. This avoids using Azure's NextMarker entirely and correctly handles
both unpaginated and paginated requests.
Azure Storage's StageBlock REST API rejects Content-Length: 0
with InvalidHeaderValue. The tests (PresignedAuth_UploadPart,
UploadPart_success) upload a nil/empty body, which causes the
Azure SDK to send Content-Length: 0. Azurite is lenient and
accepts it; real Azure Storage does not.
Use a new metadata key ("Zerobytesparts") sett on the
.sgwtmp/multipart/<uploadId>/<object-hash> blob to track and
0 length parts.
Fixes#1849
If no `Content-Type` is provided during object upload, S3 defaults it to `application/octet-stream`. This behavior was missing in the gateway, causing backends to persist an empty `Content-Type`, which Fiber then overrides with its default `text/plain`. The behavior has now been corrected for the object upload operations: `PutObject`, `CreateMultipartUpload`, and `CopyObject`.
CopyObject was failing with NoSuchKey when source keys contained special
characters like {} or spaces. The X-Amz-Copy-Source header is URL-encoded
by clients, but ParseCopySource wasn't decoding before filesystem access.
Added url.QueryUnescape() to properly decode bucket and object names,
fixing copy operations for keys with special characters.
Fixing this also uncovered an errors with azure blob url encoding with
similar special character handling. Added this fix in for the integration
tests to pass.

This PR focuses on correcting so-called "list-limiter" parsing and validation. The affected limiters include: `max-keys`, `max-uploads`, `max-parts`, `max-buckets`, `max-uploads` and `part-number-marker`. When a limiter value is outside the integer range, a specific `InvalidArgument` error is now returned. If the value is a valid integer but negative, a different `InvalidArgument` error is produced.
`max-buckets` has its own validation rules: completely invalid values and values outside the allowed range (`1 <= input <= 10000`) return distinct errors. For `ListObjectVersions`, negative `max-keys` values follow S3’s special-case behavior and return a different `InvalidArgument` error message.
Additionally, `GetObjectAttributes` now follows S3 semantics for `x-amz-max-parts`: S3 ignores invalid values, so the gateway now matches that behavior.
Fixes#1792Fixes#1747Fixes#1797Fixes#1799
This PR primarily introduces delimiter support and several bug fixes for the `ListMultipartUploads` action in the POSIX and Azure backends. Delimiter handling is now implemented — when a delimiter is present in multipart-upload object key names, the backend collects and returns the appropriate common prefixes.
This functionality is achieved by introducing a common multipart-upload lister in the backend package. All backends (Azure, POSIX) now use this lister. The lister accepts a list that is already sorted and filtered by `KeyMarker` and `Prefix`.
Previously, the `KeyMarker` was required to exactly match an existing multipart-upload object key. This restriction is removed. The listing now relies on a lexicographical comparison between the provided `KeyMarker` and existing multipart-upload object keys.
Validation for `UploadIdMarker` is also added to correctly return an `InvalidArgument` error for invalid upload IDs. If `KeyMarker` is missing, the `UploadIdMarker` is ignored entirely. If `KeyMarker` is provided, a valid upload ID is one that matches an upload belonging to *the first object key after the KeyMarker*. For example, if the `KeyMarker` is `foo`, but the provided `UploadIdMarker` corresponds to an upload under `quxx`, it is invalid. It must match one of the uploads for the next object key equal to `foo`.
Finally, this PR fixes multipart-upload sorting. Multipart uploads must be sorted primarily lexicographically by their object key, and secondarily—when multiple uploads share the same object key—by their initiation time in ascending order.
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.
Closes#1731
Implements the admin `CreateBucket` (`PATCH /:bucket/create`) endpoint and CLI command, which create a new bucket with the provided owner access key ID. The endpoint internally calls the S3 `CreateBucket` API, storing the new owner information in the request context under the `bucket-owner` key. This value is then retrieved by the S3 API layer and the backends.
The endpoint uses the custom `x-vgw-owner` HTTP header to pass the bucket owner access key ID.
The admin CLI command mirrors `aws s3api create-bucket` and supports all flags implemented by the gateway (for example, `--create-bucket-configuration`, `--acl`, `--object-ownership`, etc.).
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.
Closes#1346
`GetObject` and `HeadObject` return the `x-amz-tagging-count` header in the response, which specifies the number of tags associated with the object. This was already supported for `GetObject`, but missing for `HeadObject`. This implementation adds support for `HeadObject` in `azure` and `posix` and updates the integration tests to cover this functionality for `GetObject`.
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)
Closes#1595
This implementation diverges from AWS S3 behavior. The `CreateBucket` request body is no longer ignored. Based on the S3 request body schema, the gateway parses only the `LocationConstraint` and `Tags` fields. If the `LocationConstraint` does not match the gateway’s region, it returns an `InvalidLocationConstraint` error.
In AWS S3, tagging during bucket creation is supported only for directory buckets. The gateway extends this support to general-purpose buckets.
If the request body is malformed, the gateway returns a `MalformedXML` error.
Fixes#1565Fixes#1561Fixes#1300
This PR focuses on three main changes:
1. **Prioritizing object-level lock configuration over bucket-level default retention**
When an object is uploaded with a specific retention configuration, it takes precedence over the bucket’s default retention set via `PutObjectLockConfiguration`. If the object’s retention expires, the object must become available for write operations, even if the bucket-level default retention is still active.
2. **Preventing object lock configuration from being disabled once enabled**
To align with AWS S3 behavior, once object lock is enabled for a bucket, it can no longer be disabled. Previously, sending an empty `Enabled` field in the payload would disable object lock. Now, this behavior is removed—an empty `Enabled` field will result in a `MalformedXML` error.
This creates a challenge for integration tests that need to clean up locked objects in order to delete the bucket. To handle this, a method has been implemented that:
* Removes any legal hold if present.
* Applies a temporary retention with a "retain until" date set 3 seconds ahead.
* Waits for 3 seconds before deleting the object and bucket.
3. **Allowing object lock to be enabled on existing buckets via `PutObjectLockConfiguration`**
Object lock can now be enabled on an existing bucket if it wasn’t enabled at creation time.
* If versioning is enabled at the gateway level, the behavior matches AWS S3: object lock can only be enabled when bucket versioning status is `Enabled`.
* If versioning is not enabled at the gateway level, object lock can always be enabled on existing buckets via `PutObjectLockConfiguration`.
* In Azure (which does not support bucket versioning), enabling object lock is always allowed.
This change also fixes the error message returned in this scenario for better clarity.
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.
Fixes#1520
Removes the incorrect logic for HeadObject returning successful response, when querying an incomplete multipart upload.
Implements the logic to return `NotImplemented` error if `GetObject`/`HeadObject` is attempted with `partNumber` in azure and posix backends. The front-end part is preserved to be used in s3 proxy backend.
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.
Closes#882
Implements conditional reads for `GetObject` and `HeadObject` in the gateway for both POSIX and Azure backends. The behavior is controlled by the `If-Match`, `If-None-Match`, `If-Modified-Since`, and `If-Unmodified-Since` request headers, where the first two perform ETag comparisons and the latter two compare against the object’s `LastModified` date. No validation is performed for invalid ETags or malformed date formats, and precondition date headers are expected to follow RFC1123; otherwise, they are ignored.
The Integration tests cover all possible combinations of conditional headers, ensuring the feature is 100% AWS S3–compatible.
This changes the marker/continuation token from the object name
to the marker from the azure list objects pager. This is needed
because passing the object name as the token to the azure next
call causes the Azure API to throw 400 Bad Request with
InvalidQueryParameterValue. So we have to use the azure marker
for compatibility with the azure API pager.
To do this we have to align the s3 list objects request to the
Azure ListBlobsHierarchyPager. The v2 requests have an optional
startafter where we will have to page through the azure blobs
to find the correct starting point, but after this we will
only return with the single paginated results form the Azure
pager to maintain the correct markers all the way through to
Azure.
The ListObjects (non V2) assumes that the marker must be an object
name, so for this case we have to page through the azure listings
for each call to find the correct starting point. This makes the
V2 method far more efficient, but maintains correctness for the
ListObjects.
Also remove continuation token string checks in the integration
tests since this is supposed to be an opaque token that the
client should not care about. This will help to maintain the
tests for mutliple backend types.
Fixes#1457
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.
The C++ SDK (and maybe others?) assume that the S3 ETags
without a "-" in the string are MD5 checksums. So the Azure
ETag that does not have a "-" but also is not an MD5 checksum
will fail some of the sdk internal validation checks.
Fix this by appending "-1" to the ETag to make it look like
the multipart format ETag that will skip the sdk verfication
check.

Add helper util auth.UpdateBucketACLOwner() that sets new
default ACL based on new owner and removes old bucket policy.
The ChangeBucketOwner() remains in the backend.Backend
interface in case there is ever a backend that needs to manage
ownership in some other way than with bucket ACLs. The arguments
are changing to clarify the updated owner. This will break any
plugins implementing the old interface. They should use the new
auth.UpdateBucketACLOwner() or implement the corresponding
change specific for the backend.
There were a couple of cases that would return an error for the
non existing bucket acl instead of treating that as the default
acl.
This also cleans up the backends that were doing their own
acl parsing instead of using the auth.ParseACL() function.
Fixes#1304

Adds range queries support for `HeadObject`.
Fixes the range parsing logic for `GetObject`, which is used for `HeadObject` as well. Both actions follow the same rules for range parsing.
Fixes the error message returned by `GetObject`.
The xml encoding for the s3.CompleteMultipartUploadOutput response
type was not producing exactly the right field names for the
expected complete multipart upload result.
This change follows the pattern we have had to do for other xml
responses to create our own type that will encode better to the
expected response.
This will change the backend.Backend interface, so plugins and
other backends will have to make the corresponding changes.

`PutObject`, `CopyObject` and `CreateMultipartUpload` accept tag string as an http request header which should be url-encoded. The tag string should be a valid url-encoded string and each key/value pair should be valid, otherwise they should fail with `APIError`.
If the provided tag set contains duplicate `keys` the calls should fail with the same `InvalidURLEncodedTagging` error.
Not all url-encoded characters are supported by `S3`. The tagging string should contain only `letters`, `digits` and the following special chars:
- `-`
- `.`
- `/`
- `_`
- `+`
- ` `(space)
And their url-encoded versions: e.g. `%2F`(/), `%2E`(.) ... .
If the provided tagging string contains invalid `key`/`value`, the calls should fail with the following errors respectively:
`invalid key` - `(InvalidTag) The TagKey you have provided is invalid`
`invalid value` - `(InvalidTag) The TagValue you have provided is invalid`

- For invalid tag keys, it creates a new error: `ErrInvalidTagKey`.

ListObjects returns object owner data in each object entity in the result, while ListObjectsV2 has fetch-owner query param, which indicates if the objects owner data should be fetched.
