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.
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.
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.
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#1385
When accessing a specific object version, the user must have the `s3:GetObjectVersion` permission in the bucket policy. The `s3:GetObject` permission alone is not sufficient for a regular user to query object versions using `HeadObject`.
This PR fixes the issue and adds integration tests for both `HeadObject` and `GetObject`. It also includes cleanup in the integration tests by refactoring the creation of user S3 clients, and moves some test user data to the package level to avoid repetition across tests.
