`OpMuxConnectError` was not handled correctly.
Remove local checks for single request handlers so they can
run before being registered locally.
Bonus: Only log IAM bootstrap on startup.

While healing the latest changes of expiry rules across sites
if target had pre existing transition rules, they were getting
overwritten as cloned latest expiry rules from remote site were
getting written as is. Fixed the same and added test cases as
well.

moveToTrash() function moves a folder to .trash, for example, when
doing some object deletions: a data dir that has many parts will be
renamed to the trash folder; However, ENOSPC is a valid error from
rename(), and it can cripple a user trying to free some space in an
entire disk situation.
Therefore, this commit will try to do a recursive delete in that case.
This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom
values for quorum under batch replication, and
key rotation.
this PR allows following policy
```
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Deny a presigned URL request if the signature is more than 10 min old",
"Effect": "Deny",
"Action": "s3:*",
"Resource": "arn:aws:s3:::DOC-EXAMPLE-BUCKET1/*",
"Condition": {
"NumericGreaterThan": {
"s3:signatureAge": 600000
}
}
}
]
}
```
This is to basically disable all pre-signed URLs that are older than 10 minutes.
AWS S3 closes keep-alive connections frequently
leading to frivolous logs filling up the MinIO
logs when the transition tier is an AWS S3 bucket.
Ignore such transient errors, let MinIO retry
it when it can.
When minio runs with MINIO_CI_CD=on, it is expected to communicate
with the locally running SUBNET. This is happening in the case of MinIO
via call home functionality. However, the subnet-related functionality inside the
console continues to talk to the SUBNET production URL. Because of this,
the console cannot be tested with a locally running SUBNET.
Set the env variable CONSOLE_SUBNET_URL correctly in such cases.
(The console already has code to use the value of this variable
as the subnet URL)
Optionally allows customers to enable
- Enable an external cache to catch GET/HEAD responses
- Enable skipping disks that are slow to respond in GET/HEAD
when we have already achieved a quorum
Bonus: allow replication to attempt Deletes/Puts when
the remote returns quorum errors of some kind, this is
to ensure that MinIO can rewrite the namespace with the
latest version that exists on the source.
This PR adds a WebSocket grid feature that allows servers to communicate via
a single two-way connection.
There are two request types:
* Single requests, which are `[]byte => ([]byte, error)`. This is for efficient small
roundtrips with small payloads.
* Streaming requests which are `[]byte, chan []byte => chan []byte (and error)`,
which allows for different combinations of full two-way streams with an initial payload.
Only a single stream is created between two machines - and there is, as such, no
server/client relation since both sides can initiate and handle requests. Which server
initiates the request is decided deterministically on the server names.
Requests are made through a mux client and server, which handles message
passing, congestion, cancelation, timeouts, etc.
If a connection is lost, all requests are canceled, and the calling server will try
to reconnect. Registered handlers can operate directly on byte
slices or use a higher-level generics abstraction.
There is no versioning of handlers/clients, and incompatible changes should
be handled by adding new handlers.
The request path can be changed to a new one for any protocol changes.
First, all servers create a "Manager." The manager must know its address
as well as all remote addresses. This will manage all connections.
To get a connection to any remote, ask the manager to provide it given
the remote address using.
```
func (m *Manager) Connection(host string) *Connection
```
All serverside handlers must also be registered on the manager. This will
make sure that all incoming requests are served. The number of in-flight
requests and responses must also be given for streaming requests.
The "Connection" returned manages the mux-clients. Requests issued
to the connection will be sent to the remote.
* `func (c *Connection) Request(ctx context.Context, h HandlerID, req []byte) ([]byte, error)`
performs a single request and returns the result. Any deadline provided on the request is
forwarded to the server, and canceling the context will make the function return at once.
* `func (c *Connection) NewStream(ctx context.Context, h HandlerID, payload []byte) (st *Stream, err error)`
will initiate a remote call and send the initial payload.
```Go
// A Stream is a two-way stream.
// All responses *must* be read by the caller.
// If the call is canceled through the context,
//The appropriate error will be returned.
type Stream struct {
// Responses from the remote server.
// Channel will be closed after an error or when the remote closes.
// All responses *must* be read by the caller until either an error is returned or the channel is closed.
// Canceling the context will cause the context cancellation error to be returned.
Responses <-chan Response
// Requests sent to the server.
// If the handler is defined with 0 incoming capacity this will be nil.
// Channel *must* be closed to signal the end of the stream.
// If the request context is canceled, the stream will no longer process requests.
Requests chan<- []byte
}
type Response struct {
Msg []byte
Err error
}
```
There are generic versions of the server/client handlers that allow the use of type
safe implementations for data types that support msgpack marshal/unmarshal.
With an odd number of drives per erasure set setup, the write/quorum is
the half + 1; however the decommissioning listing will still list those
objects and does not consider those as stale.
Fix it by using (N+1)/2 formula.

Immediate transition use case and is mostly used to fill warm
backend with a lot of data when a new deployment is created
Currently, if the transition queue is complete, the transition will be
deferred to the scanner; change this behavior by blocking the PUT request
until the transition queue has a new place for a transition task.
Currently, once the audit becomes offline, there is no code that tries
to reconnect to the audit, at the same time Send() quickly returns with
an error without really trying to send a message the audit endpoint; so
the audit endpoint will never be online again.
Fixing this behavior; the current downside is that we miss printing some
logs when the audit becomes offline; however this information is
available in prometheus
Later, we can refactor internal/logger so the http endpoint can send errors to
console target.
