2.28.0
^^^^^^
New Features
************
* "swift-manage-shard-ranges" improvements:
* Exit codes are now applied more consistently:
* 0 for success
* 1 for an unexpected outcome
* 2 for invalid options
* 3 for user exit
As a result, some errors that previously resulted in exit code 2
will now exit with code 1.
* Added a new 'repair' command to automatically identify and
optionally resolve overlapping shard ranges.
* Added a new 'analyze' command to automatically identify
overlapping shard ranges and recommend a resolution based on a
JSON listing of shard ranges such as produced by the 'show'
command.
* Added a "--includes" option for the 'show' command to only
output shard ranges that may include a given object name.
* Added a "--dry-run" option for the 'compact' command.
* The 'compact' command now outputs the total number of
compactible sequences.
* Partition power increase improvements:
* The relinker now spawns multiple subprocesses to process disks
in parallel. By default, one worker is spawned per disk; use the
new "--workers" option to control how many subprocesses are used.
Use "--workers=0" to maintain the previous behavior.
* The relinker can now target specific storage policies or
partitions by using the new "--policy" and "--partition" options.
* More daemons now support systemd notify sockets.
* The container-reconciler now scales out better with new
"processes", "process", and "concurrency" options, similar to the
object-expirer.
Deprecation Notes
*****************
* Container sharding deprecations:
* Added a new config option, "shrink_threshold", to specify the
absolute size below which a shard will be considered for
shrinking. This overrides the "shard_shrink_point" configuration
option, which expressed this as a percentage of
"shard_container_threshold". "shard_shrink_point" is now
deprecated.
* Similar to above, "expansion_limit" was added as an absolute-
size replacement for the now-deprecated "shard_shrink_merge_point"
configuration option.
Bug Fixes
*********
* Sharding improvements:
* When building a listing from shards, any failure to retrieve
listings will result in a 503 response. Previously, failures
fetching a partiucular shard would result in a gap in listings.
* Container-server logs now include the shard path in the referer
field when receiving stat updates.
* Added a new config option, "rows_per_shard", to specify how many
objects should be in each shard when scanning for ranges. The
default is "shard_container_threshold / 2", preserving existing
behavior.
* Added a new config option, "minimum_shard_size". When scanning
for shard ranges, if the final shard would otherwise contain fewer
than this many objects, the previous shard will instead be
expanded to the end of the namespace (and so may contain up to
"rows_per_shard + minimum_shard_size" objects). This reduces the
number of small shards generated. The default value is
"rows_per_shard / 5".
* The sharder now correctly identifies and fails audits for shard
ranges that overlap exactly.
* The sharder and swift-manage-shard-ranges now consider total row
count (instead of just object count) when deciding whether a shard
is a candidate for shrinking.
* If the sharder encounters shard range gaps while cleaving, it
will now log an error and halt sharding progress. Previously, rows
may not have been moved properly, leading to data loss.
* Sharding cycle time and last-completion time are now available
via swift-recon.
* Fixed an issue where resolving overlapping shard ranges via
shrinking could prematurely mark created or cleaved shards as
active.
* S3 API improvements:
* Added an option, "ratelimit_as_client_error", to return 429s for
rate-limited responses. Several clients/SDKs have seem to support
retries with backoffs on 429, and having it as a client error
cleans up logging and metrics. By default, Swift will respond 503,
matching AWS documentation.
* Fixed a server error in bucket listings when "s3_acl" is enabled
and staticweb is configured for the container.
* Fixed a server error when a client exceeds "client_timeout"
during an upload. Now, a "RequestTimeout" error is correctly
returned.
* Fixed a server error when downloading multipart uploads/static
large objects that have missing or inaccessible segments. This is
a state that cannot arise in AWS, so a new "BrokenMPU" error is
returned, indicating that retrying the request is unlikely to
succeed.
* Fixed several issues with the prefix, marker, and delimiter
parameters that would be mirrored back to clients when listing
buckets.
* Partition power increase fixes:
* The relinker now performs eventlet-hub selection the same way as
other daemons. In particular, "epolls" will no longer be selected,
as it seemed to cause occassional hangs.
* Partitions that encountered errors during relinking are no
longer marked as completed in the relinker state file. This
ensures that a subsequent relink will retry the failed partitions.
* Partition cleanup is more robust, decreasing the likelihood of
leaving behind mostly-empty partitions from the old partition
power.
* Improved relinker progress logging, and started collecting
progress information for swift-recon.
* Cleanup is more robust to files and directories being deleted by
another process.
* The relinker better handles data found from earlier partition
power increases.
* The relinker better handles tombstones found for the same object
but with different inodes.
* The reconciler now defers working on policies that have a
partition power increase in progress to avoid issues with
concurrent writes.
* Erasure coding fixes:
* Added the ability to quarantine EC fragments that have no (or
few) other fragments in the cluster. A new configuration option,
"quarantine_threshold", in the reconstructor controls the point at
the fragment will be quarantined; the default (0) will never
quarantine. Only fragments older than "quarantine_age" (default:
"reclaim_age") may be quarantined. Before quarantining, the
reconstructor will attempt to fetch fragments from handoff nodes
in addition to the usual primary nodes; a new "request_node_count"
option (default "2 * replicas") limits the total number of nodes
to contact.
* Added a delay before deleting non-durable data. A new
configuration option, "commit_window" in the "[DEFAULT]" section
of object-server.conf, adjusts this delay; the default is 60
seconds. This improves the durability of both back-dated PUTs
(from the reconciler or container-sync, for example) and fresh
writes to handoffs by preventing the reconstructor from deleting
data that the object-server was still writing.
* Improved proxy-server and object-reconstructor logging when data
cannot be reconstructed.
* Fixed an issue where some but not all fragments having metadata
applied could prevent reconstruction of missing fragments.
* Server-side copying of erasure-coded data to a replicated policy
no longer copies EC sysmeta. The previous behavior had no material
effect, but could confuse operators examining data on disk.
* Python 3 fixes:
* Fixed a server error when performing a PUT authorized via
tempurl with some proxy pipelines.
* Fixed a server error during GET of a symlink with some proxy
pipelines.
* Fixed an issue with logging setup when /dev/log doesn't exist or
is not a UNIX socket.
* The dark-data audit watcher now skips objects younger than a new
configurable "grace_age" period. This avoids issues where data could
be flagged, quarantined, or deleted because of listing consistency
issues. The default is one week.
* The dark-data audit watcher now requires that all primary
locations for an object's container agree that the data does not
appear in listings to consider data "dark". Previously, a network
partition that left an object node isolated could cause it to
quarantine or delete all of its data.
* "EPIPE" errors no longer log tracebacks.
* The account and container auditors now log and update recon before
going to sleep.
* The object-expirer logs fewer client disconnects.
* "swift-recon-cron" now includes the last time it was run in the
recon information.
* "EIO" errors during read now cause object diskfiles to be
quarantined.
* The formpost middleware now properly supports uploading multiple
files with different content-types.
* Various other minor bug fixes and improvements.
