features:
- |
Change the behavior of the EC reconstructor to perform a
fragment rebuild to a handoff node when a primary peer responds
with 507 to the REPLICATE request. This changes EC to match the
existing behavior of replication when drives fail. After a
rebalance of EC rings (potentially removing unmounted/failed
devices), it's most IO efficient to run in handoffs_only mode to
avoid unnecessary rebuilds.
- |
O_TMPFILE support is now detected by attempting to use it
instead of looking at the kernel version. This allows older
kernels with backported patches to take advantage of the
O_TMPFILE functionality.
- |
Add slo_manifest_hook callback to allow other middlewares to
impose additional constraints on or make edits to SLO manifests
before being written. For example, a middleware could enforce
minimum segment size or insert data segments.
- |
Fixed an issue with multi-region EC policies that caused the EC
reconstructor to constantly attempt cross-region rebuild
traffic.
- |
Fixed an issue where S3 API v4 signatures would not be validated
against the body of the request, allowing a replay attack if
request headers were captured by a malicious third party.
- Display crypto data/metadata details in swift-object-info.
- formpost can now accept a content-encoding parameter.
- |
Fixed an issue where multipart uploads with the S3 API would
sometimes report an error despite all segments being upload
successfully.
- |
Multipart object segments are now actually deleted when the
multipart object is deleted via the S3 API.
- |
Swift now returns a 503 (instead of a 500) when an account
auto-create fails.
- |
Fixed a bug where encryption would store the incorrect key
metadata if the object name starts with a slash.
- |
Fixed an issue where an object server failure during a client
download could leave an open socket between the proxy and
client.
- |
Fixed an issue where deleted EC objects didn't have their
on-disk directories cleaned up. This would cause extra resource
usage on the object servers.
- |
Fixed issue where bulk requests using xml and expect
100-continue would return a malformed HTTP response.
- Various other minor bug fixes and improvements.
