without atomic load() it is possible that for
a slow receiver we would get into a hot-loop, when
logCh is full and there are many incoming callers.
to avoid this as a workaround enable BATCH_SIZE
greater than 100 to ensure that your slow receiver
receives data in bulk to avoid being throttled in
some manner.
this PR however fixes the unprotected access to
the current workers value.
Add the inlined data as base64 encoded field and try to add a string version if feasible.
Example:
```
λ xl-meta -data xl.meta
{
"8e03504e-1123-4957-b272-7bc53eda0d55": {
"bitrot_valid": true,
"bytes": 58,
"data_base64": "Z29sYW5nLm9yZy94L3N5cyB2MC4xNS4wIC8=",
"data_string": "golang.org/x/sys v0.15.0 /"
}
```
The string will have quotes, newlines escaped to produce valid JSON.
If content isn't valid utf8 or the encoding otherwise fails, only the base64 data will be added.
`-export` can still be used separately to extract the data as files (including bitrot).
Add partial shard reconstruction
* Add partial shard reconstruction
* Fix padding causing the last shard to be rejected
* Add md5 checks on single parts
* Move md5 verified to `verified/filename.ext`
* Move complete (without md5) to `complete/filename.ext.partno`
It's not pretty, but at least now the md5 gives some confidence it works correctly.
precondition check was being honored before, validating
if anonymous access is allowed on the metadata of an
object, leading to metadata disclosure of the following
headers.

although the information presented is minimal in nature,
and of opaque nature. It still simply discloses that an
object by a specific name exists or not without even having
enough permissions.
This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
Add combination of multiple parts.
Parts will be reconstructed and saved separately and can manually be combined to the complete object.
Parts will be named `(version_id)-(filename).(partnum).(in)complete`.
Adds `-xver` which can be used with `-export` and `-combine` to attempt to combine files across versions if data is suspected to be the same. Overlapping data is compared.
Bonus: Make `inspect` accept wildcards.
Metrics being added:
- read_tolerance: No of drive failures that can be tolerated without
disrupting read operations
- write_tolerance: No of drive failures that can be tolerated without
disrupting write operations
- read_health: Health of the erasure set in a pool for read operations
(1=healthy, 0=unhealthy)
- write_health: Health of the erasure set in a pool for write operations
(1=healthy, 0=unhealthy)
Instead of having "online" and "healing" as two metrics, replace with a
single metric "health" which can have following values:
0 = offline
1 = healthy
2 = healing
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.

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.

Since the standard process collector implements only a subset of these
metrics, remove it and implement our own custom process collector that
captures all the process metrics we need.
Since the object is being permanently deleted, the lack of read quorum should not
matter as long as sufficient disks are online to complete the deletion with parity
requirements.
If several pools have the same object with insufficient read quorum, attempt to
delete object from all the pools where it exists
