This change enables embedding files in ZIP with custom permissions.
Also uses default creds for starting MinIO based on inspect data.

objects with 10,000 parts and many of them can
cause a large memory spike which can potentially
lead to OOM due to lack of GC.
with previous PR reducing the memory usage significantly
in #17963, this PR reduces this further by 80% under
repeated calls.
Scanner sub-system has no use for the slice of Parts(),
it is better left empty.

- this PR avoids sending a large ChecksumInfo slice
when its not needed
- also for a file with XLV2 format there is no reason
to allocate Checksum slice while reading
Keys are helpful to ensure the strict ordering of messages, however currently the
code uses a random request id for every log, hence using the request-id
as a Kafka key is not serve any purpose;
This commit removes the usage of the key, to also fix the audit issue from
internal subsystem that does not have a request ID.
to track the replication transfer rate across different nodes,
number of active workers in use and in-queue stats to get
an idea of the current workload.
This PR also adds replication metrics to the site replication
status API. For site replication, prometheus metrics are
no longer at the bucket level - but at the cluster level.
Add prometheus metric to track credential errors since uptime
replicationTimestamp might differ if there were retries
in replication and the retried attempt overwrote in
quorum but enough shards with newer timestamp causing
the existing timestamps on xl.meta to be invalid, we
do not rely on this value for anything external.
this is purely a hint for debugging purposes, but there
is no real value in it considering the object itself
is in-tact we do not have to spend time healing this
situation.
we may consider healing this situation in future but
that needs to be decoupled to make sure that we do not
over calculate how much we have to heal.
.metacache objects are transient in nature, and are better left to
use page-cache effectively to avoid using more IOPs on the disks.
this allows for incoming calls to be not taxed heavily due to
multiple large batch listings.
given a versionId the mtime is always the same, it
can never be different than its original value.
versionIds also do not conflict, since they are uuid's
and unique practically forever.
we expect a certain level of IOPs and latency so this is okay.
fixes other miscellaneous bugs
- such as hanging on mrfCh <- when the context is canceled
- queuing MRF heal when the context is canceled
- remove unused saveStateCh channel
This commit updates the minio/kes-go dependency
to v0.2.0 and updates the existing code to work
with the new KES APIs.
The `SetPolicy` handler got removed since it
may not get implemented by KES at all and could
not have been used in the past since stateless KES
is read-only w.r.t. policies and identities.

Bonus fixes include
- do not have to write final xl.meta (renameData) does this
already, saves some IOPs.
- make sure to purge the multipart directory properly using
a recursive delete, otherwise this can easily pile up and
rely on the stale uploads cleanup.
fixes#17863
This reverts commit bf3901342c.
This is to fix a regression caused when there are inconsistent
versions, but one version is in quorum. SuccessorModTime issue
must be fixed differently.
batch status can perpetually wait after completion
due to a race between the MetricsHandler() returning
the active metrics in intervals of 1sec and delete
of metrics after job completion.
this PR ensures that we keep the 'status' around
for a while, i.e upto 24hrs for all the batch jobs.
Two fields in lifecycles made GOB encoding consistently fail with `gob: type lifecycle.Prefix has no exported fields`.
This meant that in distributed systems listings would never be able to continue and would restart on every call.
Fix issues and be sure to log these errors at least once per bucket. We may see some connectivity errors here, but we shouldn't hide them.
When listing getObjectFileInfo can return `io.EOF` if file is being written.
When we wrap the error it will *not* retry upstream, since `io.EOF` is a valid return value.
Allow one retry before returning errors and canceling the listing.
* 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

Bonus:
- avoid calling DiskInfo() calls when missing blocks
instead heal the object using MRF operation.
- change the max_sleep to 250ms beyond that we will
not stop healing.
ignoring valid objects with valid replication metadata
after the Prefix was disabled must still honor the older
metadata.
this can lead to unexpected results, allow it during
READ phase always.
// UnmarshalStrict is like Unmarshal except that any fields that are found
// in the data that do not have corresponding struct members, or mapping
// keys that are duplicates, will result in
// an error.
batch replication pull must preserve versionID regardless
of destination bucket versioning configuration.
This is similar to the issue with decommissioning and rebalancing
health checks were missing for drives replaced since
- HealFormat() would replace the drives without a health check
- disconnected drives when they reconnect via connectEndpoint()
the loop also loses health checks for local disks and merges
these into a single code.
- other than this separate cleanUp, health check variables to avoid
overloading them with similar requirements.
- also ensure that we compete via context selector for disk monitoring
such that the canceled disks don't linger around longer waiting for
the ticker to trigger.
- allow disabling active monitoring.

Limit large uploads (> 128MiB) to a max of 10 workers, intent is to avoid
larger uploads from using all replication bandwidth, giving room for smaller
uploads to sync faster.
