Fixes#1688
S3 returns a specific `InvalidRequest` error for the requests with `?versions` query param against `object` resource. The PR implements this error route.
Fixes#1707
The `Expect` HTTP header is ignored by the AWS SDK SigV4 signer and is omitted during signature calculation. As a result, the signature is computed incorrectly when the `Expect` header is included in the signed headers. This PR removes the `Expect` header from the SigV4 ignored headers list in the SDK-derived source code.
Fixes#1698
`PutObjectTagging`, `GetObjectTagging` and `DeleteObjectTagging` return the `x-amz-version-id` in the response headers. The PR adds this header in the responses.
Fixes#1686
GetObjectTagging previously returned a `NoSuchTagSet` error when no object tags were set. This has been fixed, and an empty tag set is now returned instead.
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.
The `x-amz-if-match-size` parsing debug log used to appear for all `DeleteObject` calls when the header was missing. An empty-string check was missing, which led to attempting to parse an empty string into an `int64`, causing a failure and triggering the debug log. This check has now been added, and the debug log is emitted only when the header is present and contains an invalid `int64` value.
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#1712
A successful `PutBucketPolicy` call returns `204`(No Content) http status. This PR fixes the response status code, by sending correct `204`, insted of `200`.
Closes#1714
There is a `Location` field in the `CompleteMultipartUpload` result that represents the newly created object URL. This PR adds this property to the `CompleteMultipartUpload` response, generating it dynamically in either host-style or path-style format, depending on the gateway configuration.
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.

This PR primarily focuses on error handling and checksum calculation for signed streaming requests of type `STREAMING-AWS4-HMAC-SHA256-PAYLOAD` and `STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER`.
It fixes the error type returned when the payload encoding is incorrect: the correct `IncompleteBody` error is now returned.
Chunk size validation has been added, enforcing the rule that only the final chunk may be smaller than 8192 bytes.
The `x-amz-trailer` header value is now validated against the checksum trailer present in the payload. For `STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER` requests, if no checksum trailer is provided in the payload, the gateway now returns an `IncompleteBody` error.
If there is a mismatch between the `x-amz-trailer` header and the checksum trailer in the payload, or if the checksum header key in the payload is invalid, a `MalformedTrailer` error is returned.
The `x-amz-decoded-content-length` header value is now compared against the actual decoded payload length, and an `IncompleteBody` error is returned if there is a mismatch.
Finally, the double checksum calculation issue has been fixed. For `STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER` requests, the trailing checksum is now parsed from the request payload and stored in the backend, instead of being recalculated by the backend.
The error check for the SDK call in `GetObjectAttributes` in the S3 proxy backend was missing, which caused the gateway to panic in all cases where the SDK method returned an error. The error check has now been added so that the method returns an error when the SDK call fails.
The `openssl`/`curl` command generator script in `rest_scripts` supports both unsigned streaming payload trailers and signed streaming requests. This update adds support for signed streaming requests with trailers (`STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER`).
**Usage**
The script generates an OpenSSL command file, which is then used to send the request.
Example:
```bash
go run tests/rest_scripts/generateCommand.go \
--awsAccessKeyId access \
--awsSecretAccessKey secret \
--client openssl \
--commandType putObject \
--bucketName test \
--payload "hello" \
--payloadType STREAMING-UNSIGNED-PAYLOAD-TRAILER \
--chunkSize 8192 \
--objectKey obj \
--filePath req.txt \
--checksumType crc64nvme
```
You can then send the request with:
```bash
openssl s_client -connect 127.0.0.1:7070 -ign_eof < req.txt > response.raw
```
