18847 - reading less than available prevent next onDataAvailable

Status: RESOLVED WONTFIX

(Core Graveyard :: Java-Implemented Plugins, defect, P3)

Description

[Victor V. Lapitskiy]

The required policy of reading data from stream argument
of onDataAvailable method isn't specified. In case when
in onDataAvailable method the amount of read data is less than
available and after that return occured, then next call
of onDataAvailable will never occur.
So the required policy (for example minimum of read data)
should be specified or next calls of onDataAvailable in the case
described above should occur.

Steps to Reproduce:
1)use the following implementation for your
  PlugletStreamListener.onDataAvailable method:

    public void onDataAvailable(PlugletStreamInfo plugletInfo, InputStream
input,int  length) {
	try{
	    System.out.println("PlugletStreamListener.onDataAvailable");
	    System.out.println("input.available is "+input.available());
	    int amount = input.available() - 1;
	    byte[] buf = new byte[amount];
	    int l = input.read(buf, 0, amount);
	    System.out.println("Read amount is "+l);
	} catch(Exception e) {
	    ;
	}

    }


2)for the value of src attribute use the file with such size that more
  than one call of onDataAvailable should occur (in current
  implementation it is sufficient to use any file with size
  more than 100K)

3)load the corresponding page to start your pluglet

Actual Results:
Your will see that only one call of onDataAvailbale occur and
the file will not be loaded completely.

Expected Results:
The next calls of onDataAvailable should occur or such
implementation of the method should be incorrect based on specification.
