This change adds Windows functional test execution in CI and updates
backend handling so windows filesystem error/path semantics map correctly
to expected S3 outcomes.
The only meta supported on windows right now is sidecar, so the tests
in windows mode also skip sidecar skips.
Future work is to address the skips and/or more clearly document
the unsupported/incompatible behavior on windows.
The windows support will still remain best effort, but these tests
should at least flag when future changes introduce incompatible
behavior on windows.
Add a new non-AWS error ErrNoSpaceLeftOnDevice (HTTP 507 Insufficient
Storage) to s3err. Update all call sites in the posix backend that
could return ENOSPC and return the new error when the underlying
filesystem has no space remaining.
Fixes#2093
Unlike xattr metadata which is tied to the filesystem object and removed
automatically, sidecar metadata lives in a parallel directory tree and
must be deleted explicitly. Add DeleteAttributes calls after removing
bucket directories, null-version files, and versioned object files.
Also add an os.Stat existence check in GetObjectTagging and
PutObjectTagging when no versionId is given, since sidecar's
StoreAttribute/RetrieveAttribute do not naturally return ErrNotExist
for missing objects the way xattr operations do.
On Windows, a file apparently cannot be renamed while an open
handle to it exists.
The previous code used defer tempfile.Close(), which meant the
handle was still open when os.Rename was called, producing:
failed to rename temporary file: The process cannot access
the file because it is being used by another process.
Fix by closing the file explicitly before the rename.
Fixes#2021
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.
