features:
- >
Ring files now include byteorder information about the endian of
the machine used to generate the file, and the values are
appropriately byteswapped if deserialized on a machine with a
different endianness.
Newly created ring files will be byteorder agnostic, but
previously generated ring files will still fail on different
endian architectures. Regenerating older ring files will cause
them to become byteorder agnostic. The regeneration of the ring
files will not cause any new data movement. Newer ring files
will still be usable by older versions of Swift (on machines
with the same endianness--this maintains existing behavior).
- >
All 416 responses will now include a Content-Range header with
an unsatisfied-range value. This allows the caller to know the
valid range request value for an object.
- >
TempURLs now support a validation against a common prefix. A
prefix-based signature grants access to all objects which share the
same prefix. This avoids the creation of a large amount of signatures,
when a whole container or pseudofolder is shared.
- >
In SLO manifests, the `etag` and `size_bytes` keys are now fully
optional and not required. Previously, the keys needed to exist
but the values were optional. The only required key is `path`.
- Respect server type for --md5 check in swift-recon.
fixes:
- Correctly handle deleted files with if-none-match requests.
- >
Correctly send 412 Precondition Failed if a user sends an
invalid copy destination. Previously Swift would send a 500
Internal Server Error.
- Fixed a rare infinite loop in `swift-ring-builder` while placing parts.
- >
Ensure update of the container by object-updater, removing a rare
possibility that objects would never be added to a container listing.
- >
Fixed non-deterministic suffix updates in hashes.pkl where a partition
may be updated much less often than expected.
- >
Fixed regression in consolidate_hashes that occurred when a new
file was stored to new suffix to a non-empty partition. This bug
was introduced in 2.7.0 and could cause an increase in rsync
replication stats during and after upgrade, due to inconsistent
hashing of partition suffixes.
- >
Account and container databases will now be quarantined if the
database schema has been corrupted.
- Remove empty db hash and suffix directories if a db gets quarantined.
other:
- >
Removed "in-process-" from func env tox name to work with
upstream CI.
- Various other minor bug fixes and improvements.
