What did you do?

I am using minio for Object storage. Minio is a golang project using go1.12 as the base go version.
The server is HTTP2 enabled. I use using minio java client which uses okhttp3 . when i try to store the object in a bucket in multi threaded mode i get okhttp3.internal.http2.StreamResetException: stream was reset: NO_ERROR.
Refer minio/minio#7501 .

okhttp3.OkHttpClient uses http2.0 by default which causes such issue.
If i forcefuly set the protocol to 1.1 ,it works fine.
Refer PR minio/minio-java#766.

I find there is some issue with Go1.12 or okhttp3 as i found this issue in the community.
Refer square/okhttp#3955
The only solution provided there was to revert to HTTP1_1 .

Setting the protocol to 1.1 is not the solution as i am not using the functionality of HTTP2.0 enabled server.

Raised the issue with okhhttp refer square/okhttp#4964
Below is the code which replicates the problem

import io.minio.MinioClient;
class PutObjectRunnable implements Runnable {
   MinioClient client;
   String bucketName;
   String filename;

   public PutObjectRunnable(MinioClient client, String bucketName, String filename) {
       this.client = client;
       this.bucketName = bucketName;
       this.filename = filename;
   }

   public void run() {
       StringBuffer traceBuffer = new StringBuffer();

       try {

           client.putObject(bucketName, filename, filename);

       } catch (Exception e) {
           System.err.print(traceBuffer.toString());
           e.printStackTrace();
       }
   }
}


public class ThreadedPutObject {
    public static void main(String args[]) throws Exception {
	try{
        MinioClient client = new MinioClient("https://play.min.io:9000", "Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG", true);
        client.traceOn(System.out);
        long startTime = System.currentTimeMillis();
		 boolean found = minioClient.bucketExists("my-bucketname");
      if (found) {
        System.out.println("my-bucketname already exists");
      } else {
        // Create bucket 'my-bucketname'.
        minioClient.makeBucket("my-bucketname");
        System.out.println("my-bucketname is created successfully");
      }

      for (int i = 0; i < 7; i++) {
            PutObjectRunnable pr = new PutObjectRunnable(client, "my-bucketname",location[i] );
          threads[i] = new Thread(pr);
      }
      for (int i = 0; i < 7; i++) {
        threads[i].start();
      }
            // Waiting for threads to complete.
      for (int i = 0; i < 7; i++) {
         threads[i].join();
          System.out.println(i);
        }
        // All threads are completed.
        } catch (Exception e) {

Can you run the Minio server with GODEBUG=http2debug=2 and paste the logs ?

@sinhaashish Next time please give us exact steps to reproduce the issue. The code above is incomplete and knowing to use the 6.0.5 version was not very obvious.
In the end, my version works just fine. I uploaded 7 files, 2 were the minio java client jars, 4 were the source and class files, and then a dummy file.

@fraenkel : Can you try it a multiple of times, as the issue is sporadic for me too.

@sinhaashish I have reproduced the issue. I am still determining the root cause. There are multiple issues going on here which is why it will take some time.

I see cases where the client side is reusing a closed stream and the server eventually says to GOAWAY.
After that point, it becomes a constant barage of PROTOCOL_ERROR which then subsides. New connections are created until we hit another issue which is exceeded the number of concurrent streams.
This is when the server side goes into a hard loop.

I will let you know more as I dig deeper.

@agnivade agnivade changed the title stream was reset: PROTOCOL_ERROR x/net/http2: stream was reset: PROTOCOL_ERROR Apr 20, 2019

@agnivade agnivade added this to the Go1.13 milestone Apr 20, 2019

Working backwards, the crazy looping looks like a minio issue which I have no plans to debug. The call stack is about 45 calls deep and the majority is minio and gorilla. Most of the threads are stuck waiting to read data from the body. This is when the number of concurrent requests is exceeded.

Other times, I see minio also stuck trying to grab locks during PutObject. This too is not something I will debug.

The only remaining investigation is the very first issue that occurs.

The very first error that occurs looks like a client initiated issue.

After the new connection is established, we then run into the issues listed above.

So far I don't see anything that points to an issue on the server side. Someone needs to investigate the client issue first.

What does it mean by client initiated issue ? Are you saying okhttp is buggy here ?

I can only tell you what I see. Someone would have to debug the client side to see what is going on.

Can you tell me exactly what that might be? - @fraenkel would like to share this with okhttp project?

@fraenkel in this scenario the cause is HTTP 2.0 failing with HTTP 1.1 we don't see these issues at all. NOTE: nodes are also communicating over HTTP 2.0 with TLS connections as well as clients.
