This improves the performance of certain queries dramatically,
such as 'count(*)' etc.

Almost a 250% improvement in performance. This PR avoids a lot of type
conversions and instead relies on raw sequences of data and interprets
them lazily.

User's key should satisfy the requirement of `mc config host add`.
Check access key and secret key length before adding a new user,
avoid creating a useless user which cannot be added into config
host or log into the browser.
This is done such that if WSO2 was re-configured
with new TLS certs, and newer tokens are signed
with a newer public key. Once populated parse the JWT
again
Commit 5c13765168 removed postgre registration triggerd
by the automatic gofmt command but it was the only where pg is registered. This commit
fixes behavior and adds unit tests to check whether postgre & sql are registered or not.
This PR introduces two new features
- AWS STS compatible STS API named AssumeRoleWithClientGrants
```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```
This API endpoint returns temporary access credentials, access
tokens signature types supported by this API
- RSA keys
- ECDSA keys
Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.
- External policy engine support, in this case OPA policy engine
- Credentials are stored on disks
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.
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.
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
A bug concerning the validation of connectionString is found,
however there is no solution to fix it for now, postgresql API
doesn't help to do that hence disabling validation of that field.
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.
* Revert "Encrypted reader wrapped in NewGetObjectReader should be closed (#6383)"
This reverts commit 53a0bbeb5b.
* Revert "Change SelectAPI to use new GetObjectNInfo API (#6373)"
This reverts commit 5b05df215a.
* Revert "Implement GetObjectNInfo object layer call (#6290)"
This reverts commit e6d740ce09.
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.
