rpcClient should attempt a reconnect if the call fails
with 'rpc.ErrShutdown' this is needed since at times when
the servers are taken down and brought back up.
The hijacked connection from net.Dial is usually closed.
So upon first attempt rpcClient might falsely indicate that
disk to be down, to avoid this state make another dial attempt
to really fail.

- abstract out instrumentation information.
- use separate lockInstance type that encapsulates the nsMutex, volume,
path and opsID as the frontend or top-level lock object.
This is done by not making the methods of the BucketMetaState interface
as methods (via type nesting) on the type implementing
RPCs (s3PeerAPIHandlers).
- 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.
- The benchmark initialization function was not taking into account the
instance type (FS/XL), was using XL ObjectLayer even for FS
benchmarks.
- This was leading to incorrect benchmark results for FS related
benchmarks.
- The fix takes into account the instance type (FS/XL) and correctly
returns FS backend for FS benchmarks.
Do not attempt to fetch volume/drive information for
each i/o situation. In our case we do this in all calls
`posix.go` this in-turn created a terrible situation for
windows. This issue does not affect the i/o path on Unix
platforms since statvfs calls are in the range of micro
seconds on these platforms.
This verification is only needed during startup and we
let things fail at a later stage on windows.
- Reads and writes of uploads.json in XL now uses quorum for
newMultipart, completeMultipart and abortMultipart operations.
- Each disk's `uploads.json` file is read and updated independently for
adding or removing an upload id from the file. Quorum is used to
decide if the high-level operation actually succeeded.
- Refactor FS code to simplify the flow, and fix a bug while reading
uploads.json.
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 FS or single-node XL mode, there is no need to save listener
configuration to persistent storage. As there is only one server, if it
is restarted, any connected listenBucketAPI clients were disconnected
and will have to reconnect - so there is nothing to actually store.
This incidentally solves #3052 by avoiding the problem.
- When modifying notification configuration
- When modifying listener configuration
- When modifying policy configuration
With this change we also stop early checking if the bucket exists, since
that uses a Read-lock and causes a deadlock due to the outer Write-lock.
opsID, a variable on the stack, changes over the course of
Completemultipartupload function in xl-v1-multipart.go. This was
being used in a function closure which was passed to defer
statement. The variables used in the closure depend on their values at
the time of evaluation which is indeterminate behaviour. It is
incorrect to depend on values of variables on stack at the end of
function, when deferred functions are executed.
Added clear subcommand for control lock with following options:
```
3. Clear lock named 'bucket/object' (exact match).
$ minio control lock clear http://localhost:9000/bucket/object
4. Clear all locks with names that start with 'bucket/prefix' (wildcard match).
$ minio control lock --recursive clear http://localhost:9000/bucket/prefix
5. Clear all locks older than 10minutes.
$ minio control lock --older-than=10m clear http://localhost:9000/
6. Clear all locks with names that start with 'bucket/a' and that are older than 1hour.
$ minio control lock --recursive --older-than=1h clear http://localhost:9000/bucket/a
```
This makes sure that when SSL is enabled (for FS/single node mode),
the server address is picked up from the --address option (that needs
to include the hostname for SSL verification, and has to be input
appropriately by user), instead of just using ":<port>".
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.
In a multipart upload scenario disks going down and coming backup
can lead to certain parts missing on the disk/server which was
going down. This is a valid case since these blocks can be
missing and should be healed through heal operation. But we are
not supposed to fail prematurely since we have enough data on
the other disks as well within read-quorum.
This fix relaxes previous assumption, fixes a major corruption
issue reproduced by @vadmeste.
Fixes#2976
Don't close socket while re-initializing notify-listeners, as the rpc
client object is shared between notify-listeners and peer clients.
Also, improves SendRPC() readability by using GetPeerClient().
Fixes a serialisation bug - encoding/gob does not directly support
serializing `map[string]interface{}`, so we serialise to JSON and send a
byte array in the RPC call, and deserialize and update on the receiver.
* 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`
* Add test coverage for removeEntry and removeEntryIfExists

... remove panic() which was added as interim aid for debugging.
* Add unit-tests to cover v4 streaming signature

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.
* The user is required to specify a table name and database connection
information in the configuration file.
* INSERTs and DELETEs are done via prepared statements for speed.
* Assumes a table structure, and requires PostgreSQL 9.5 or above due to

a query like:
CREATE TABLE myminio (

ElasticSearch and Redis are both treated like a database.
Each indexs are based on the object names uniquely indentifying
the event. Upon each delete event of the named object deletes
the index on elasticsearch and redis respectively.

- Follow up comments in issue https://github.com/minio/minio/issues/2208
for more details.
- gjson parsing of parts from xl.json for listParts.

- Fix distributed branch to be able to run XL local disks.
- Ignore initialization failures of notification and bucket
policies, the codepath should load whatever is possible.
From the S3 layer after PutObject we were calling GetObjectInfo for bucket notification. This can
be avoided if PutObjectInfo returns ObjectInfo.
