Added support to enable object lock on bucket creation in posix and azure
backends.
Implemented the logic to add object legal hold and retention on object creation
in azure and posix backends.
Added the functionality for HeadObject to return object lock related headers.
Added integration tests for these features.
There are a few cases where parsing, validations checks, etc
error details are getting lost with the more generic error
responses. This add some opt-in debug logging to log more
info for these various error cases.
Fixes#444. For some clients using chunked uploads with a zero
length file, the content length value from the request headers
was coming back as an empty string. If this happens, just set
it to "0" so that we can successfully parse this to int value.
Fixes#447. Previously we required XML namespace and got these
errors with this input:
DEBUG: <Tagging><TagSet><Tag><Key>mykey</Key><Value>myvalue</Value></Tag></TagSet></Tagging>
DEBUG: expected element <Tagging> in name space http://s3.amazonaws.com/doc/2006-03-01/ but have no name space
This adds the default ACL to the CreateBucket backend method so
that the backend doesn't need to know how to construct and ACL.
This also moves the s3proxy ACLs to a tag key/value because the
gateway ACLs are not the same accounts as the backend s3 server.
TODO: we may need to mask this tag key/value if we add support
for the Get/PutBucketTagging API.
This builds on the previous work that sets up the body streaming
for the put object and put part requests. This adds the auth and
checksum readers to postpone the v4auth checks and the content
checksum until the end of the body stream.
This means that the backend with start reading the data from the
body stream before the request is fully validated and signatures
checked. So the backend must check the error returned from the
body reader for the final auth and content checks. The backend
is expected to discard the data upon error.
This should increase performance and reduce memory utilization
to no longer require caching the entire request body in memory
for put object and put part.
* fix: Object tag actions cleanup
* fix: Fixes#249, Changed ListObjects default max-keys from -1 to 1000
* fix: Fixes#250, Added support to provide a marker not from the objects list and list the objects after the provided marker in ListObjects(V2) actions
* feat: Closes#256, Addded a check step, to compare object metadatas and allow the copying to itself, if the metadata has been changed
* fix: Simplified range assignment in CopyObject posix function
