500k is a reasonable limit for any single MinIO
cluster deployment, in future we may increase this
value.
However for now we are going to keep this limit.
site replication errors were printed at
various random locations, repeatedly - this
PR attempts to remove double logging and
capture all of them at a common place.
This PR also enhances the code to show
partial success and errors as well.
when the site is being removed is missing replication config. This can
happen when a new deployment is brought in place of a site that
is lost/destroyed and needs to delink old deployment from site
replication.
space characters at the beginning or at the end can lead to
confusion under various UI elements in differentiating the
actual name of "policy, user or group" - to avoid this behavior
this PR onwards we shall reject such inputs for newer entries.
existing saved entries will behave as is and are going to be
operable until they are removed/renamed to something more
meaningful.
- New sub-system has "region" and "name" fields.
- `region` subsystem is marked as deprecated, however still works, unless the
new region parameter under `site` is set - in this case, the region subsystem is
ignored. `region` subsystem is hidden from top-level help (i.e. from `mc admin
config set myminio`), but appears when specifically requested (i.e. with `mc
admin config set myminio region`).
- MINIO_REGION, MINIO_REGION_NAME are supported as legacy environment variables for server region.
- Adds MINIO_SITE_REGION as the current environment variable to configure the
server region and MINIO_SITE_NAME for the site name.
This unit allows users to limit the maximum number of noncurrent
versions of an object.
To enable this rule you need the following *ilm.json*
```
cat >> ilm.json <<EOF
{
"Rules": [
{
"ID": "test-max-noncurrent",
"Status": "Enabled",
"Filter": {
"Prefix": "user-uploads/"
},
"NoncurrentVersionExpiration": {
"MaxNoncurrentVersions": 5
}
}
]
}
EOF
mc ilm import myminio/mybucket < ilm.json
```
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

Removes RLock/RUnlock for updating metadata,
since we already take a write lock to update
metadata, this change removes reading of xl.meta
as well as an additional lock, the performance gain
should increase 3x theoretically for
- PutObjectRetention
- PutObjectLegalHold
This optimization is mainly for Veeam like
workloads that require a certain level of iops
from these API calls, we were losing iops.
This change allows a set of MinIO sites (clusters) to be configured
for mutual replication of all buckets (including bucket policies, tags,
object-lock configuration and bucket encryption), IAM policies,
LDAP service accounts and LDAP STS accounts.
This reverts commit 91567ba916.
Revert because the error was incorrectly converted, there are
callers that rely on errConfigNotFound and it also took away
the migration code.
Instead the correct fix is PutBucketTaggingHandler() which
is already added.
once we have competed for locks, verify if the
context is still valid - this is to ensure that
we do not start readdir() or read() calls on the
drives on canceled connections.
we will allow situations such as
```
a/b/1.txt
a/b
```
and
```
a/b
a/b/1.txt
```
we are going to document that this usecase is
not supported and we will never support it, if
any application does this users have to delete
the top level parent to make sure namespace is
accessible at lower level.
rest of the situations where the prefixes get
created across sets are supported as is.
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`
- GetObject() should always use a common dataDir to
read from when it starts reading, this allows the
code in erasure decoding to have sane expectations.
- Healing should always heal on the common dataDir, this
allows the code in dangling object detection to purge
dangling content.
These both situations can happen under certain types of
retries during PUT when server is restarting etc, some
namespace entries might be left over.
It is possible in some scenarios that in multiple pools,
two concurrent calls for the same object as a multipart operation
can lead to duplicate entries on two different pools.
This PR fixes this
- hold locks to serialize multiple callers so that we don't race.
- make sure to look for existing objects on the namespace as well
not just for existing uploadIDs
