for MinIO?

``MinIO`` is fully conformant with Golang style. Refer: [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) article from Golang project. If you observe offending code, please feel free to send a pull request or ping us on [Slack](https://slack.min.io)....

    writer.write("Hi");
    writer.close();

    assertThrows(IOException.class, () -> writer.write(" Greg"));

    assertThrows(IOException.class, () -> writer.flush());

    // close()ing already closed writer is allowed
    writer.close();
  }

The benefit of raising an exception over `return`ing a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

```Python hl_lines="11"

		if peer == nil {
			continue
		}
		peer.Listen(ctx, mergeCh, values)
	}

	var (
		emptyEventTicker <-chan time.Time
		keepAliveTicker  <-chan time.Time
	)

	if p := values.Get("ping"); p != "" {
		pingInterval, err := strconv.Atoi(p)
		if err != nil {
			writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrInvalidQueryParams), r.URL)
			return
		}
		if pingInterval < 1 {

# Release 2.0.0

## Major Features and Improvements

TensorFlow 2.0 focuses on **simplicity** and **ease of use**, featuring updates
like:

    assertThat(frameLog(true, 0, 0, TYPE_SETTINGS, 0x1))
      .isEqualTo("<< 0x00000000     0 SETTINGS      ACK")
    assertThat(frameLog(true, 0, 8, TYPE_PING, 0x1))
      .isEqualTo("<< 0x00000000     8 PING          ACK")
    assertThat(frameLog(true, 3, 0, TYPE_HEADERS, 0x1))
      .isEqualTo("<< 0x00000003     0 HEADERS       END_STREAM")
    assertThat(frameLog(true, 3, 0, TYPE_DATA, 0x1))

	}
	if n != len(p) {
		err = io.ErrShortWrite
		b.closeWithErr(err)
	}
	return n, err
}

func (b *streamingBitrotWriter) Close() error {
	// Close the underlying writer.
	// This will also flush the ring buffer if used.
	err := b.iow.Close()

	// Wait for all data to be written before returning else it causes race conditions.
	// Race condition is because of io.PipeWriter implementation. i.e consider the following

	biggerBufMin = 32 << 10

	// This is the maximum size of bigger buffers.
	biggerBufMax = maxBufferSize

	// If there is a queue, merge up to this many messages.
	maxMergeMessages = 50

	// clientPingInterval will ping the remote handler every 15 seconds.
	// Clients disconnect when we exceed 2 intervals.
	clientPingInterval = 15 * time.Second

	// Deadline for single (non-streaming) requests to complete.
