Also adding an API to allow resyncing replication when
existing object replication is enabled and the remote target
is entirely lost. With the `mc replicate reset` command, the
objects that are eligible for replication as per the replication
config will be resynced to target if existing object replication
is enabled on the rule.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
IAM not initialized doesn't mean we can't still
read the content from the disk, we should just
allow the request to go-through if object layer
is initialized.
Real-time metrics calculated in-memory rely on the initial
replication metrics saved with data usage. However, this can
lag behind the actual state of the cluster at the time of server
restart leading to inaccurate Pending size/counts reported to
Prometheus. Dropping the Pending metrics as this can be more
reliably monitored by applications with replication notifications.

LDAPusername is the simpler form of LDAPUser (userDN),
using a simpler version is convenient from policy
conditions point of view, since these are unique id's
used for LDAP login.
In cases where a cluster is degraded, we do not uphold our consistency
guarantee and we will write fewer erasure codes and rely on healing
to recreate the missing shards.
In some cases replacing known bad disks in practice take days.
We want to change the behavior of a known degraded system to keep
the erasure code promise of the storage class for each object.
This will create the objects with the same confidence as a fully
functional cluster. The tradeoff will be that objects created
during a partial outage will take up slightly more space.
This means that when the storage class is EC:4, there should
always be written 4 parity shards, even if some disks are unavailable.
When an object is created on a set, the disks are immediately
checked. If any disks are unavailable additional parity shards
will be made for each offline disk, up to 50% of the number of disks.
We add an internal metadata field with the actual and intended
erasure code level, this can optionally be picked up later by
the scanner if we decide that data like this should be re-sharded.
Bonus change LDAP settings such as user, group mappings
are now listed as part of `mc admin user list` and
`mc admin group list`
Additionally this PR also deprecates the `/v2` API
that is no longer in use.
A configured audit logger or HTTP logger is validated during MinIO
server startup. Relax the timeout to 10 seconds in that case, otherwise,
both loggers won't be used.
1 second could be too low for a busy HTTP endpoint.
This commit fixes a bug causing the MinIO server to compute
the ETag of a single-part object as MD5 of the compressed
content - not as MD5 of the actual content.
This usually does not affect clients since the MinIO appended
a `-1` to indicate that the ETag belongs to a multipart object.
However, this behavior was problematic since:
- A S3 client being very strict should reject such an ETag since
the client uploaded the object via single-part API but got
a multipart ETag that is not the content MD5.
- The MinIO server leaks (via the ETag) that it compressed the
object.
This commit addresses both cases. Now, the MinIO server returns
an ETag equal to the content MD5 for single-part objects that got
compressed.

A lot of healing is likely to be on non-existing objects and
locks are very expensive and will slow down scanning
significantly.
In cases where all are valid or, all are broken allow
rejection without locking.
Keep the existing behavior, but move the check for
dangling objects to after the lock has been acquired.
```
_, err = getLatestFileInfo(ctx, partsMetadata, errs)
if err != nil {
return er.purgeObjectDangling(ctx, bucket, object, versionID, partsMetadata, errs, []error{}, opts)
}
```
Revert "heal: Hold lock when reading xl.meta from disks (#12362)"
This reverts commit abd32065aa
This PR fixes two bugs
- Remove fi.Data upon overwrite of objects from inlined-data to non-inlined-data
- Workaround for an existing bug on disk with latest releases to ignore fi.Data
and instead read from the disk for non-inlined-data
- Addtionally add a reserved metadata header to indicate data is inlined for
a given version.
Lock is hold in healObject() after reading xl.meta from disks the first
time. This commit will held the lock since the beginning of HealObject()

Compressed files always start at the beginning of a part so no additional offset should be added.
Previous PR #12351 added functions to read from the reader
stream to reduce memory usage, use the same technique in
few other places where we are not interested in reading the
data part.
