Issue #120 routes an existing SSE-C replica through PutObjectHandler and
NewMultipartUploadHandler. On main those handlers assigned the incoming retention
and legal hold directly, without the source-timestamp ordering #111 added to
CopyObjectHandler and without persisting the ordering timestamps, so in
active-active replication a retransmit carrying an older value could overwrite a
destination version's newer lock state.
Share #111's ordering decision as applyReplicatedObjectLock in
cmd/bucket-object-lock.go and call it from CopyObject, PUT and multipart
initiation. A request that is not an actual trusted replica keeps ordinary write
semantics (a validated value is applied and stamped now); only a real replica
update is ordered against the stored version, so a marker-only peer write no
longer drops a validated hold or default retention. CopyObject keeps its SSE-C
key-rotation encMetadata reconciliation inline. putReplicationOpts now emits a
stored retention ordering timestamp even when the value keys are absent, so a
removal recorded on the retransmit PUT path still replicates onward. replicateAll
marks Failed and carries the error when putReplicationOpts fails.
The handler decision is made against the version as it stands then, which a
concurrent lock update can outrun before the write commits, and for multipart
across the whole initiation-to-completion span. Close that window under the
object write lock the receiving erasure set holds: a trusted SSE-C replica full
write sets ObjectOptions.ReplicaLockReconcile, and erasureObjects.PutObject and
CompleteMultipartUpload re-run the ordering (reconcileStoredObjectLock, which
orders retention and legal hold independently by their reserved timestamps)
against the destination version read on that set before committing. Persisted
upload metadata records the null version as an empty VersionID, so completion
looks that up as the null version rather than the latest. The reconcile runs only
against an existing version; a not-found destination keeps the write's own
accepted lock, including a pre-upgrade upload that persisted values without
ordering timestamps, and a non-not-found read error fails the write. Scoped to
the SSE-C paths this issue enables; CopyObject is left as #111 wrote it.
Scope: this orders Object Lock against the destination version under the write
lock and is correct for a single erasure set. A multi-pool deployment -- where a
version can have duplicate copies across pools, object ModTime ties do not track
per-field lock timestamps, and the object namespace lock is per-pool -- needs a
cross-pool lock-safe reconcile and is deliberately out of scope here, tracked in
pgsty/silo#TBD-multipool-lock.
Tests: TestAPISSECReplicaRetransmitObjectLockOrdering and its multipart sibling;
TestAPIReplicaMultipartNewerHoldSurvivesCompletion and
TestReplicaPutObjectLockReconcileUnderWriteLock (a hold or retention reaching the
version after the handler decision, or after multipart initiation, survives the
commit; a pre-upgrade upload on an absent version keeps its lock);
TestReplicaLockReconcileNullVersion (a null-version completion reconciles the null
version, not a coexisting UUID version, and an absent null version keeps its
accepted lock); TestAPIReplicaMarkerOnlyAppliesObjectLock; TestReplicaStoredLock;
the timestamp-only putReplicationOpts round trip; and the retransmit, exemption
and target-head tests. The #111 CopyObject replica suite and the existing #120
suite stay green, as do the PUT/multipart handler and object-layer regression
suites. Compatibility: the shared helper preserves #111's CopyObject behavior; a
non-replica PUT or multipart initiation that sets Object Lock now also stamps the
reserved ordering timestamp, matching CopyObject since #111; only trusted SSE-C
replica writes take the in-lock reconcile.

Return AWS-compatible errors for CompleteMultipartUpload checksum failures without changing the global streaming checksum mapping. Compare explicit multipart checksum types symmetrically, distinguish missing composite part checksums, and preserve the CRC64NVME canonicalization pending a direct AWS probe.

Use Walk(), which is a recursive listing with versioning, to check if
the bucket has some objects before being removed. This is beneficial
because the bucket can contain multiple dangling objects in multiple
drives.
Also, this will prevent a bug where a bucket is deleted in a deployment
that has many erasure sets but the bucket contains one or few objects
not spread to enough erasure sets.
Rebalance-stop can race with ongoing rebalance operations. This change
prevents these operations from overwriting objects by checking the source
and destination pool indices are different.
Currently, bucket metadata is being loaded serially inside ListBuckets
Objet API. Fix that by loading the bucket metadata as the number of
erasure sets * 10, which is a good approximation.
skip healing properly in scanner when drive is hotplugged
due to how the state is passed around the SkipHealing
might not be the true state() of the system always, causing
a situation where we might healing from the scanner on the
same drive which is being. Due to this competing heals get
triggered that slow each other down.
If used, 'opts.Marker` will cause many missed entries since results are returned
unsorted, and pools are serialized.
Switch to fully concurrent listing and merging across pools to return sorted entries.
This reverts commit 928c0181bf.
This change was not correct, reverting.
We track 3 states with the ProxyRequest header - if replication process wants
to know if object is already replicated with a HEAD, it shouldn't proxy back

- Use a shared worker pool for all ILM expiry tasks
- Free version cleanup executes in a separate goroutine
- Add a free version only if removing the remote object fails
- Add ILM expiry metrics to the node namespace
- Move tier journal tasks to expiryState
- Remove unused on-disk journal for tiered objects pending deletion
- Distribute expiry tasks across workers such that the expiry of versions of
the same object serialized
- Ability to resize worker pool without server restart
- Make scaling down of expiryState workers' concurrency safe; Thanks
@klauspost
- Add error logs when expiryState and transition state are not
initialized (yet)
* metrics: Add missed tier journal entry tasks
* Initialize the ILM worker pool after the object layer
This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom
values for quorum under batch replication, and
key rotation.
Optionally allows customers to enable
- Enable an external cache to catch GET/HEAD responses
- Enable skipping disks that are slow to respond in GET/HEAD
when we have already achieved a quorum
AccountInfo is quite frequently called by the Console UI
login attempts, when many users are logging in it is important
that we provide them with better responsiveness.
- ListBuckets information is cached every second
- Bucket usage info is cached for up to 10 seconds
- Prefix usage (optional) info is cached for up to 10 secs
Failure to update after cache expiration, would still
allow login which would end up providing information
previously cached.
This allows for seamless responsiveness for the Console UI
logins, and overall responsiveness on a heavily loaded
system.
* optimize deletePrefix, use direct set location via object name
instead of fanning out the calls for an object force delete
we can assume the set location and not do fan-out calls
* Apply suggestions from code review

this randomness is needed to avoid scanning
the same buckets across different erasure sets,
in the same order.
allow random buckets to be scanned instead
allowing a wider spread of ILM, replication
checks.
Additionally do not loop over twice to fill
the channel, fill the channel regardless of
having bucket new or old.
Optimize DeleteObject API to avoid extra
GetObjectInfo call on the replicating side.
For receiving side, it is just a regular
DeleteObject call.
Bonus: Fix a corner case where version purged is
absent on target (either due to replication not yet
complete or target version already deleted in a
one-way replication or when replication was disabled).
In such cases, mark version purge complete.
This PR also returns the replication status in
proxy calls and defers replication attempt if
HEAD on object version returned a error different
from NoSuchKey
Removes the bloom filter since it has so limited usability, often gets saturated anyway and adds a bunch of complexity to the scanner.
Also removes a tiny bit of CPU by each write operation.
