StorageInfo() call is supposed to give each
server/disk information independently, rely
on this appropriately so that `mc admin info server`
gets correct information all the time.
Regression from #8509 which changes objectsToDelete entry
from a list to map. This will cause index out of range
panic if object is not selected for delete.
level - this PR builds on #8120 which
added PutBucketObjectLockConfiguration and
GetBucketObjectLockConfiguration APIS
This PR implements PutObjectRetention,
GetObjectRetention API and enhances
PUT and GET API operations to display
governance metadata if permissions allow.
- added ability to specify CA for self-signed certificates
- added option to authenticate using client certificates
- added unit tests for nats connections
We should only read ahead if we are reading big files. We enable it for files >= 16MB.

The 64KB buffer is actually a small disadvantage for this case, but I believe it will be better in general than no buffer.
- Migrate and save only settings which are enabled
- Rename logger_http to logger_webhook and
logger_http_audit to audit_webhook
- No more pretty printing comments, comment
is a key=value pair now.
- Avoid quotes on values which do not have space in them
- `state="on"` is implicit for all SetConfigKV unless
specified explicitly as `state="off"`
- Disabled IAM users should be disabled always
The code does not properly set a new deployemnt ID when not present
in format.json: it loops twice without releasing write lock on format.json
causing an infinite locking error on the same file.
This commit fixes and simplifies a little the code.
This PR implements locking from a global entity into
a more localized set level entity, allowing for locks
to be held only on the resources which are writing
to a collection of disks rather than a global level.
In this process this PR also removes the top-level
limit of 32 nodes to an unlimited number of nodes. This
is a precursor change before bring in bucket expansion.
This PR also fixes issues related to
- Add proper newline for `mc admin config get` output
for more than one targets
- Fixes issue of temporary user credentials to have
consistent output
- Fixes a crash when setting a key with empty values
- Fixes a parsing issue with `mc admin config history`
- Fixes gateway ENV handling for etcd server and gateway
This PR fixes issues found in config migration
- StorageClass migration error when rrs is empty
- Plain-text migration of older config
- Do not run in safe mode with incorrect credentials
- Update logger_http documentation for _STATE env
Refer more reported issues at #8434
This PR refactors object layer handling such
that upon failure in sub-system initialization
server reaches a stage of safe-mode operation
wherein only certain API operations are enabled
and available.
This allows for fixing many scenarios such as
- incorrect configuration in vault, etcd,
notification targets
- missing files, incomplete config migrations
unable to read encrypted content etc
- any other issues related to notification,
policies, lifecycle etc
This PR brings support for `history` list to
list in the following agreed format
```
~ mc admin config history list -n 2 myminio

This PR also moves the help templating and coloring to
fully `mc` side instead than `madmin` API.
This PR adds code to appropriately handle versioning issues
that come up quite constantly across our API changes. Currently
we were also routing our requests wrong which sort of made it
harder to write a consistent error handling code to appropriately
reject or honor requests.
This PR potentially fixes issues
- old mc is used against new minio release which is incompatible
returns an appropriate for client action.
- any older servers talking to each other, report appropriate error
- incompatible peer servers should report error and reject the calls
with appropriate error
This is to avoid making calls to backend and requiring
gateways to allow permissions for ListBuckets() operation
just for Liveness checks, we can avoid this and make
our liveness checks to be more performant.
- Supports migrating only when the credential ENVs are set,
so any FS mode deployments which do not have ENVs set will
continue to remain as is.
- Credential ENVs can be rotated using MINIO_ACCESS_KEY_OLD
and MINIO_SECRET_KEY_OLD envs, in such scenarios it allowed
to rotate the encrypted content to a new admin key.
This commit replaces the returned error message by
the hardware info handler from `Method-Not-Allowed`
to `Bad-Request` since the current HTTP error is not
correct according to the HTTP spec.
In particular:
```
The origin server MUST generate an Allow header field
in a 405 response containing a list of the target
resource's currently supported methods.
```

- This PR allows config KVS to be validated properly
without being affected by ENV overrides, rejects
invalid values during set operation
- Expands unit tests and refactors the error handling
for notification targets, returns error instead of
ignoring targets for invalid KVS
- Does all the prep-work for implementing safe-mode
style operation for MinIO server, introduces a new
global variable to toggle safe mode based operations
NOTE: this PR itself doesn't provide safe mode operations
The new auto healing model selects one node always responsible
for auto-healing the whole cluster, erasure set by erasure set.
If that node dies, another node will be elected as a leading
operator to perform healing.
This code also adds a goroutine which checks each 10 minutes
if there are any new unformatted disks and performs its healing
in that case, only the erasure set which has the new disk will
be healed.
