Current implementation simply uses all the memory locally
and crashes when a large upload is initiated using Minio
browser UI.
This PR uploads stream in blocks and finally commits the blocks
allowing for low memory footprint while uploading large objects
through Minio browser UI.
This PR also adds ETag compatibility for single PUT operations.

This to ensure that we heal all entries in config/
prefix, we will have IAM and STS related files which
are being introduced in #6168 PR
This is a change to ensure that we heal all of them
properly, not just `config.json`
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.
When download profiling data API fails to gather profiling data
from all nodes for any reason (including profiler not enabled),
return 400 http code with the appropriate json message.
httpRespToErrorResponse() usually reads the http response when
the http error code is not expected to parse the json error
response in the http body, however it was never properly closing
the connection. This PR fixes the behavior.
This PR simplifies the process of developer build of local
docker containers using `make docker`.
You need to provide a TAG i.e
```
TAG=y4m4/minio:exp make docker
```
This commit adds two functions for removing
confidential information - like SSE-C keys -
from HTTP headers / object metadata.
This creates a central point grouping all
headers/entries which must be filtered / removed.

The new call combines GetObjectInfo and GetObject, and returns an
object with a ReadCloser interface.
Also adds a number of end-to-end encryption tests at the handler
level.
Allow minio s3 gateway to use aws environment credentials,
IAM instance credentials, or AWS file credentials.
If AWS_ACCESS_KEY_ID, AWS_SECRET_ACCSES_KEY are set,
or minio is running on an ec2 instance with IAM instance credentials,
or there is a file $HOME/.aws/credentials, minio running as an S3
gateway will authenticate with AWS S3 using those one of credentials.
The lookup order:
1. AWS environment varaibles
2. IAM instance credentials
3. $HOME/.aws/credentials
4. minio environment variables
To authenticate with the minio gateway, you will always use the
minio environment variables MINIO_ACCESS_KEY MINIO_SECRET_KEY.
Two handlers are added to admin API to enable profiling and disable
profiling of a server in a standalone mode, or all nodes in the
distributed mode.
/minio/admin/profiling/start/{cpu,block,mem}:
- Start profiling and return starting JSON results, e.g. one
node is offline.
/minio/admin/profiling/download:
- Stop the on-going profiling task
- Stream a zip file which contains all profiling files that can
be later inspected by go tool pprof
The test TestServerTLSCiphers seems to fail sometimes for
no obvious reason. Actually the test is not needed
(as unit test) since minio/mint tests the server's TLS ciphers
as part of its security tests.
Fixes#5977
Currently, one node in a cluster can fail to boot with the following error message:
```
ERROR Unable to initialize config system: Storage resources are insufficient for the write operation
```
This happens when disks are formatted, read quorum is met but write
quorum is not met. In checkServerConfig(), a insufficient read quorum
error is replaced by errConfigNotFound, the code will generate a
new config json and try to save it, but it will fail because write
quorum is not met.
Replacing read quorum with errConfigNotFound is also wrong because it
can lead, in rare cases, to overwrite the config set by the user.
So, this commit adds a retry mechanism in configuration initialization
to retry only with read or write quorum errors.
This commit will also fix the following cases:
- Read quorum is lost just after the initialization of the object layer.
- Write quorum not met when upgrading configuration version.
ReadFile RPC input argument has been changed in commit a8f5939452959d27674560c6b803daa9,
however, RPC doesn't detect such a change when it calls other nodes with older versions.
Hence, bumping RPC version.
Fixes#6458
It was expected that in gateway mode, we do not know
the backend types whereas in NAS gateway since its
an extension of FS mode (standalone) this leads to
an issue in LivenessCheckHandler() which would perpetually
return 503, this would affect all kubernetes, openshift
deployments of NAS gateway.
This commit fixes an AWS S3 incompatibility issue.
The AccessKeyID may contain one or more `/` which caused
the server to interpret parts of the AccessKeyID as
other `X-Amz-Credential` parameters (like date, region, ...)
This commit fixes this by allowing 5 or more
`X-Amz-Credential` parameter strings and only interpreting
the last 5.
Fixes#6443
