## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

MinIO uses the following disclosure process:

1. Once the security report is received one member of the security team tries to verify and reproduce
   the issue and determines the impact it has.
2. A member of the security team will respond and either confirm or reject the security report.
   If the report is rejected the response explains why.
3. Code is audited to find any potential similar problems.
4. Fixes are prepared for the latest release.

- MinIO verifies that the client certificate is valid.
- MinIO tries to find a policy that matches the `CN` of the client certificate.
- MinIO returns temp. S3 credentials associated to the found policy.

The returned credentials expiry after a certain period of time that can be configured via `&DurationSeconds=3600`. By default, the STS credentials are valid for 1 hour. The minimum expiration allowed is 15 minutes.

additional burden to have sequential hostnames for us to make sure that we can provide horizontal distribution, however we have come across situations where sometimes this is not feasible and there are no easier alternatives without modifying /etc/hosts on the host system as root user.  Many times in airgapped deployments this is not allowed or requires audits and approvals.

MinIO server configuration file allows users to provide topology that allows for heterogeneous hostnames, allowing MinIO...

implements an S3 extension to the [PostUpload](https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPOST.html) where in a special fan-out list is sent along with the TSB's for MinIO make multiple uploads from a single source stream. Optionally supports custom metadata, tags and other retention settings. All objects are also readable independently once upload is completed via the regular S3 [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) API.

(with the bucket label set). For example to query API metrics for buckets `test1` and `test2`, make a scrape request to `/minio/metrics/v3/api/bucket?buckets=test1,test2`. 

Instead of a metrics scrape, it is also possible to list the metrics that would be returned by a path. This is done by adding a `?list` query parameter. The MinIO server will then list all possible metrics that could be returned. During an actual metrics scrape, only available metrics are returned - not all of them. With...

# Ensure bucket exists, purging if asked to
createBucket() {
	BUCKET=$1
	POLICY=$2
	PURGE=$3
	VERSIONING=$4
	OBJECTLOCKING=$5

	# Purge the bucket, if set & exists
	# Since PURGE is user input, check explicitly for `true`
	if [ $PURGE = true ]; then
		if checkBucketExists $BUCKET; then
			echo "Purging bucket '$BUCKET'."
			set +e # don't exit if this fails
			${MC} rm -r --force myminio/$BUCKET

The validity duration of the generated STS credentials is the minimum of the `DurationSeconds` parameter (if passed) and the validity duration returned by the Identity Management Plugin.

## API Response

- To squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
- To run `make test` and `make build` completes.
