This PR brings an additional logger implementation
called AuditLog which logs to http targets
The intention is to use AuditLog to log all incoming
requests, this is used as a mechanism by external log
collection entities for processing Minio requests.
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.
Modified the LogIf function to log only if the error passed
is not on the ignored errors list.
Currently, only disk not found error is added to the list.
Added a new function in logger package called LogAlwaysIf,
which will print on any error.
Fixes#5997
ANSI colors do not work on dumb terminals, in situations
when minio is running as a service under systemd.
This PR ensures we turn off color in those situations.
- Add console target logging, enabled by default.
- Add http target logging, which supports an endpoint
with basic authentication (username/password are passed
in the endpoint url itself)
- HTTP target logging is asynchronous and some logs can be
dropped if channel buffer (10000) is full
In a small window, UI error tries to split lines for an eye candy
error message. However, since we show some docs.minio.io links in some
error messages, these links are actually broken and not easily selected
in a X terminal. This PR changes the behavior and won't split lines
anymore.
This commit prevents complete server failures caused by
`logger.CriticalIf` calls. Instead of calling `os.Exit(1)`
the function now executes a panic with a special value
indicating that a critical error happend. At the top HTTP
handler layer panics are recovered and if its a critical
error the client gets an InternalServerError status code.
Further this allows unit tests to cover critical-error code
paths.
Add compile time GOROOT path to the list of prefix
of file paths to be removed.
Add webhandler function names to the slice that
stores function names to terminate logging.
This is an effort to remove panic from the source.
Add a new call called CriticialIf, that calls LogIf and exits.
Replace panics with one of CriticalIf, FatalIf and a return of error.
