Subject [jira] [Created] (HTTPASYNC-40) Cannot suspend input when using AsyncByteConsumer
Date Thu, 25 Apr 2013 07:44:15 GMT
Bodo Junglas created HTTPASYNC-40:

             Summary: Cannot suspend input when using AsyncByteConsumer
                 Key: HTTPASYNC-40
                 URL: https://issues.apache.org/jira/browse/HTTPASYNC-40
             Project: HttpComponents HttpAsyncClient
          Issue Type: Bug
    Affects Versions: 4.0-beta3
            Reporter: Bodo Junglas
            Priority: Minor

When inheriting from org.apache.http.nio.client.methods.AsyncByteConsumer a suspendInput on
the iocrlt is unreliable. The core of the problem is this loop:

for (;;) {
            int bytesRead = decoder.read(this.bbuf);
            if (bytesRead <= 0) {
            onByteReceived(this.bbuf, ioctrl);

I.e. while there is anything to be read it is delivered to onByteReceived non-stop (eat or
Unluckily a situation when a server delivers its data so fast that decoder.read never returns
0 is usually also a situation when the client might want to suspend the input for a moment.

Workaround: Use AbstractAsyncResponseConsumer instead.
