Instead of an internal server error, we should be returning
method not allowed when trying to upload to a read only
filesystem or make other modifications that are expected to
fail. This will give clearer feedback to the clients
that this is not expected to work.
Fixes#1062
This adds a NoMeta MetadataStorer that might be useful for read
only filesystems that are populated with data not from the gateway.
The limitation is that no incoming metadata is stored with the
buckets or objects, and all buckets and objects will only have
default metadata.
This adds the option to store metadata for objects and buckets
within a specified directory:
bucket: <sidecar dir>/<bucket>/meta/<attribute>
object: <sidecar dir>/bucket/<object>/meta/<attribute>
Example invocation:
./versitygw -a myaccess -s mysecret posix --sidecar /tmp/sidecar /tmp/gw
The attributes are stored by name within the hidden directory.
This fixes the cases for racing uploads with the same object names.
Before we were making some bad assumptions about what would cause
an error when trying to link/rename the final object name into
the namespace, but missed the case that another upload for the
same name could be racing with this upload and causing an incorrect
error.
This also changes the order of setting metadata to prevent
accidental setting of metadata for the current upload to another
racing upload.
This also fix auth.CheckObjectAccess() when objects are removed
while this runs.
Fixes#854
The xattr package has a more universal error type for xattrs
not existing. Use this for better platform compatibility.
This also adds the xattr.XATTR_SUPPORTED check for platform
xattr suport in xattr package.
Fixes#527
