This PR adds two new admin APIs in Minio server and madmin package:
- GetConfigKeys(keys []string) ([]byte, error)
- SetConfigKeys(params map[string]string) (err error)
A key is a path in Minio configuration file, (e.g. notify.webhook.1)
The user will always send a string value when setting it in the config file,
the API will know how to convert the value to the appropriate type. The user
is also able to set a raw json.
Before setting a new config, Minio will validate all fields and try to connect
to notification targets if available.
Currently Go http connection pool was not being properly
utilized leading to degrading performance as the number
of concurrent requests increased.
As recommended by Go implementation, we have to drain the
response body and close it.
Removing an empty directory is not working because of xl.DeleteObject()
was only checking if the passed prefix is an actual object but it
should also check if it is an empty directory.
soMaxConn value is 128 on almost all linux systems,
this value is too low for Minio at times when used
against large concurrent workload e.g: spark applications
this causes a sort of SYN flooding observed by the kernel
to allow for large backlog increase this value to 2048.
With this value we do not see anymore SYN flooding
kernel messages.
ListMultipartUploads implementation is meant for docker-registry
use-case only. It lists only the first upload with a prefix matching
the object being uploaded.
When Deny ListObjects policy is set on bucket, the browser
is hanging while trying to list the object. This is now
fixed by showing appropriate error message and an
empty object list.

An issue was reproduced when minio-js client functional
tests are setting lower case http headers, in our current
master branch we specifically look for canonical host header
which may be not necessarily true for all http clients.
This leads to a perpetual hang on the *net.Conn*.
This PR fixes regression caused by #6206 by handling the
case insensitivity.
To pass a custom S3 endpoint in S3 gateway, the user needs
to specify it as an argument after 'minio gateway s3' and not
as '--address' option since this latter specifies the address
to which the gateway should listen.
This combines calling GetObjectInfo and GetObject while returning a
io.ReadCloser for the object's body. This allows the two operations to
be under a single lock, fixing a race between getting object info and
reading the object body.
One typo introduced in a recent commit miscalculates if worm and browser
are enabled or not. A simple test is also added to detect this issue
in the future if it ever happens again.
In current master when you do `mc watch` you can see a
dynamic ARN being listed which exposes the remote IP as well
```
mc watch play/airlines
```
On another terminal
```
mc admin info play

SQS ARNs listed as part of ServerInfo should be only external targets,
since listing an ARN here is not useful and it cannot be re-purposed in
any manner.
This PR fixes this issue by filtering out httpclient from the ARN list.
This is a regression introduced in #52940e4431725c
- with recent commit 1fb2e9ef95, config
can no longer be updated by editing config.json. This is because config
has been migrated inside the minio backend. Update documentation on
how to set/get configuration using mc admin config command.
This commit adds error handling for SSE-KMS requests to
HEAD, GET, PUT and COPY operations. The server responds
with `not implemented` if a client sends a SSE-KMS
request.
