- Adds an interface to update in-memory bucket metadata state called
BucketMetaState - this interface has functions to:
- update bucket notification configuration,
- bucket listener configuration,
- bucket policy configuration, and
- send bucket event
- This interface is implemented by `localBMS` a type for manipulating
local node in-memory bucket metadata, and by `remoteBMS` a type for
manipulating remote node in-memory bucket metadata.
- The remote node interface, makes an RPC call, but the local node
interface does not - it updates in-memory bucket state directly.
- Rename mkPeersFromEndpoints to makeS3Peers and refactored it.
- Use arrayslice instead of map in s3Peers struct
- `s3Peers.SendUpdate` now receives an arrayslice of peer indexes to
send the request to, with a special nil value slice indicating that
all peers should be sent the update.
- `s3Peers.SendUpdate` now returns an arrayslice of errors, representing
errors from peers when sending an update. The array positions
correspond to peer array s3Peers.peers
Improve globalS3Peers:
- Make isDistXL a global `globalIsDistXL` and remove from s3Peers
- Make globalS3Peers an array of (address, bucket-meta-state) pairs.
- Fix code and tests.
Default golang net.Listen only listens on the first IP when
host resolves to multiple IPs.
This change addresses a problem for example your ``/etc/hosts``
has entries as following
```
127.0.1.1 minio1
192.168.1.10 minio1
```
Trying to start minio as
```
minio server --address "minio1:9001" ~/Photos
```
Causes the minio server to be bound only to "127.0.1.1" which
is an incorrect behavior since we are generally interested in
`192.168.1.10` as well.
This patch addresses this issue if the hostname is resolvable
and gives back list of addresses associated with that hostname
we just bind on all of them as it is the expected behavior.
For command line arguments we are currently following
- <node-1>:/path ... <node-n>:/path
This patch changes this to
- http://<node-1>/path ... http://<node-n>/path
In a distributed setup that the server should not perform any operation
on the storage layer after it is exported via RPC. e.g, cleaning up of
temporary directories under .minio.sys/tmp may interfere with ongoing
PUT objects being served by the distributed setup.
* Implements a Peer RPC router that sends info to all Minio servers in the cluster.
* Bucket notifications are propagated to all nodes via this RPC router.
* Bucket listener configuration is persisted to separate object layer
file (`listener.json`) and peer RPCs are used to communicate changes
throughout the cluster.
* When events are generated, RPC calls to send them to other servers
where bucket listeners may be connected is implemented.
* Some bucket notification tests are now disabled as they cannot work in
the new design.
* Minor fix in `funcFromPC` to use `path.Join`
- Servers do not exit for invalid credentials instead they print and wait.
- Servers do not exit for version mismatch instead they print and wait.
- Servers do not exit for time differences between nodes they print and wait.
These messages based on our prep stage during XL
and prints more informative message regarding
drive information.
This change also does a much needed refactoring.
* Test code for controller-handler operations:
* Heal operations
* List operation
* Switch to "testing" lib, moving away from gocheck
* Minor refactors
* Remove extra call to initGracefulShutdown
* Remove dead code in mainControl:
Dead code found by the TestControlMain() test function that always
passes.
* Add tests for control-*-main.go
Initialization when disk was down the network disk
reported an incorrect error rather than errDiskNotFound.
This resulted in incorrect error handling during
prepInitStorage() stage.
Fixes#2577
This change initializes rpc servers associated with disks that are
local. It makes object layer initialization on demand, namely on the
first request to the object layer.
Also adds lock RPC service vendorized minio/dsync
