Current master repeatedly calls ListBuckets() during
initialization of multiple sub-systems
Use single ListBuckets() call for each sub-system as
follows
- LifeCycle
- Policy
- Notification
The change now is to ensure that we take custom URL as
well for updating the deployment, this is required for
hotfix deliveries for certain deployments - other than
the community release.
This commit changes the previous work d65a2c6725
with newer set of requirements.
Also deprecates PeerUptime()
- Background Heal routine receives heal requests from a channel, either to
heal format, buckets or objects
- Daily sweeper lists all objects in all buckets, these objects
don't necessarly have read quorum so they can be removed if
these objects are unhealable
- Heal daily ops receives objects from the daily sweeper
and send them to the heal routine.
- The events will be persisted in queueStore if `queueDir` is set.
- Else, if queueDir is not set events persist in memory.
The events are replayed back when the mqtt broker is back online.
Different gateway implementations due to different backend
API errors, might return different unsupported errors at
our handler layer. Current code posed a problem for us because
this information was lost and we would convert it to InternalError
in this situation all S3 clients end up retrying the request.
To avoid this unexpected situation implement a way to support
this cleanly such that the underlying information is not lost
which is returned by gateway.
More than one client can't use the same clientID for MQTT connection.
This causes problem in distributed deployments where config is shared
across nodes, as each Minio instance tries to connect to MQTT using the
same clientID.
This commit removes the clientID field in config, and allows
MQTT client to create random clientID for each node.
Returning unexpected errors can cause problems for config handling,
which is what led gateway deployments with etcd to misbehave and
had stopped working properly
Deprecate the use of Admin Peers concept and migrate all peer
communication to Notification subsystem. This finally allows
for a common subsystem for all peer notification in case of
distributed server deployments.
Especially in gateway IAM admin APIs are not enabled
if etcd is not enabled, we should enable admin API though
but only enable IAM and Config APIs with etcd configured.
clientID must be a unique `UUID` for each connections. Now, the
server generates it, rather considering the config.
Removing it as it is non-beneficial right now.
Fixes#6364
To conform with AWS S3 Spec on ETag for SSE-S3 encrypted objects,
encrypt client sent MD5Sum and store it on backend as ETag.Extend
this behavior to SSE-C encrypted objects.
In many situations, while testing we encounter
ErrInternalError, to reduce logging we have
removed logging from quite a few places which
is acceptable but when ErrInternalError occurs
we should have a facility to log the corresponding
error, this helps to debug Minio server.
This PR introduces two new features
- AWS STS compatible STS API named AssumeRoleWithClientGrants
```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```
This API endpoint returns temporary access credentials, access
tokens signature types supported by this API
- RSA keys
- ECDSA keys
Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.
- External policy engine support, in this case OPA policy engine
- Credentials are stored on disks
go test shows the following warning:

The reason for this data race is that some admin tests are not waiting for go routines
that they created to be properly exited, which triggers the race detector.
Add support for sse-s3 encryption with vault as KMS.
Also refactoring code to make use of headers and functions defined in
crypto package and clean up duplicated code.
This PR is the first set of changes to move the config
to the backend, the changes use the existing `config.json`
allows it to be migrated such that we can save it in on
backend disks.
In future releases, we will slowly migrate out of the
current architecture.
Fixes#6182
No locks are ever left in memory, we also
have a periodic interval of clearing stale locks
anyways. The lock instrumentation was not complete
and was seldom used.
Deprecate this for now and bring it back later if
it is really needed. This also in-turn seems to improve
performance slightly.
- Add console target logging, enabled by default.
- Add http target logging, which supports an endpoint
with basic authentication (username/password are passed
in the endpoint url itself)
- HTTP target logging is asynchronous and some logs can be
dropped if channel buffer (10000) is full
Minio server was preventing itself to start when any notification
target is down and not running. The PR changes the behavior by
avoiding startup abort in that case, so the user will still
be able to access Minio server using mc admin commands after
a restart or set config commands.
