If two objects share everything but one object has a slash prefix, those would be merged in listings,
with secondary properties used for a tiebreak.
Example: An object with the key `prefix/obj` would be merged with an object named `prefix/obj/`.
While this violates the [no object can be a prefix of another](https://min.io/docs/minio/linux/operations/concepts/thresholds.html#conflicting-objects), let's resolve these.
If we have an object with 'name' and a directory named 'name/' discard the directory only - but allow objects
of 'name' and 'name/' (xldir) to be uniquely returned.
Regression from #15772
canceled callers might linger around longer,
can potentially overwhelm the system. Instead
provider a caller context and canceled callers
don't hold on to them.
Bonus: we have no reason to cache errors, we should
never cache errors otherwise we can potentially have
quorum errors creeping in unexpectedly. We should
let the cache when invalidating hit the actual resources
instead.
LastPong is saved as nanoseconds after a connection or reconnection but
saved as seconds when receiving a pong message. The code deciding if
a pong is too old can be skewed since it assumes LastPong is only in
seconds.
Accept multipart uploads where the combined checksum provides the expected part count.
It seems this was added by AWS to make the API more consistent, even if the
data is entirely superfluous on multiple levels.
Improves AWS S3 compatibility.
This commit adds support for MinKMS. Now, there are three KMS
implementations in `internal/kms`: Builtin, MinIO KES and MinIO KMS.
Adding another KMS integration required some cleanup. In particular:
- Various KMS APIs that haven't been and are not used have been
removed. A lot of the code was broken anyway.
- Metrics are now monitored by the `kms.KMS` itself. For basic
metrics this is simpler than collecting metrics for external
servers. In particular, each KES server returns its own metrics
and no cluster-level view.
- The builtin KMS now uses the same en/decryption implemented by
MinKMS and KES. It still supports decryption of the previous
ciphertext format. It's backwards compatible.
- Data encryption keys now include a master key version since MinKMS
supports multiple versions (~4 billion in total and 10000 concurrent)
per key name.

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.
It is expected that whoever is using the credentials which has

AWS S3 returns the actual object size as part of XML
response for InvalidRange error, this is used apparently
by SDKs to retry the request without the range.
'opts.Marker` is causing many missed entries if used since results are returned unsorted. Also since pools are serialized.
Switch to do fully concurrent listing and merging across pools to return sorted entries.
Returning errors on listings is impossible with the current API, so document that.
Return an error at once if no drives are found instead of just returning an empty listing and no error.
This is to support deployments migrating from a multi-pooled
wider stripe to lower stripe. MINIO_STORAGE_CLASS_STANDARD
is still expected to be same for all pools. So you can satisfy
adding custom drive count based pools by adjusting the storage
class value.

ILM actions due to ExpiredObjectDeleteAllVersions and
DelMarkerExpiration are ignored when object locking is enabled on a
bucket.
Note: This applies to object versions which may not have retention
configured on them. This applies to all object versions in this bucket,
including those created before the retention config was applied.
Per-bucket metrics endpoints always start with /bucket and the bucket
name is appended to the path. e.g. if the collector path is /bucket/api,
the endpoint for the bucket "mybucket" would be
/minio/metrics/v3/bucket/api/mybucket
Change the existing bucket api endpoint accordingly from /api/bucket to
/bucket/api
The `Token` parameter is a sensitive value that should not be output in the Audit log for STS AssumeRoleWithCustomToken API.
Bonus: Add a simple tool that echoes audit logs to the console.
When listing, with drives returning `errFileNotFound,` `errVolumeNotFound`, or `errUnformattedDisk,`,
we could get below `minDisks` drives being left.
This would result in a quorum never being reachable for any object. Therefore, the listing
would continue, but no results would ever be produced.
Include `fnf` in the mindisk check since it is incremented on these errors. This will stop
listing when minDisks are left.
Allow `opts.minDisks` to not return errVolumeNotFound or errFileNotFound and return that.
That will allow for good results even if disks return something else.
We switch `errUnformattedDisk` to a regular error. If we have enough of those, we should just fail.
Typically not all drives are connected, so we delay 3 minutes before resuming.
This greatly reduces risk of starting to list unconnected drives, or drives we risk being disconnected soon.
This delay is not applied when starting with an admin call.
ConsoleUI like applications rely on combination of
ListServiceAccounts() and InfoServiceAccount() to populate
UI elements, however individually these calls can be slow
causing the entire UI to load sluggishly.
i.e., this rule element doesn't apply to DEL markers.
This is a breaking change to how ExpiredObejctDeleteAllVersions
functions today. This is necessary to avoid the following highly probable
footgun scenario in the future.
Scenario:
The user uses tags-based filtering to select an object's time to live(TTL).
The application sometimes deletes objects, too, making its latest
version a DEL marker. The previous implementation skipped tag-based filters
if the newest version was DEL marker, voiding the tag-based TTL. The user is
surprised to find objects that have expired sooner than expected.
* Add DelMarkerExpiration action
This ILM action removes all versions of an object if its
the latest version is a DEL marker.
```xml
<DelMarkerObjectExpiration>
<Days> 10 </Days>
</DelMarkerObjectExpiration>
```
1. Applies only to objects whose,
• The latest version is a DEL marker.
• satisfies the number of days criteria
2. Deletes all versions of this object
3. Associated rule can't have tag-based filtering
Includes,
- New bucket event type for deletion due to DelMarkerExpiration
calling a remote target remove with a perfectly
well constructed ARN can lead to a crash for a bucket
with no replication configured.
This PR fixes, and adds a crash check for ImportMetadata
as well.

Unfreeze as soon as the incoming connection is terminated and don't wait for everything to complete.
We don't want to keep the services frozen if something becomes stuck.
- handle errFileCorrupt properly
- micro-optimization of sending done() response quicker
to close the goroutine.
- fix logger.Event() usage in a couple of places
- handle the rest of the client to return a different error other than
lastErr() when the client is closed.
