Subject [jira] [Updated] (CMIS-906) doc.getContentStreamLength() returns the length of whole content even it is partial retrieved
Date Thu, 09 Apr 2015 08:50:12 GMT

Florian Müller updated CMIS-906:
--------------------------------
    Description: 
I have a test to just retrieve partial content:
{code:java}
public void getContentRange() throws IOException{
	    byte[] content = "Hello World, this is for contentstream range test!".getBytes();  
	    InputStream stream = new ByteArrayInputStream(content);
        ContentStream contentStream = session.getObjectFactory().createContentStream("hello.txt",
content.length, "text/plain", stream);
	    
     // (minimal set: name and object type id)
        Map<String, Object> properties = new HashMap<String, Object>();
        properties.put(PropertyIds.OBJECT_TYPE_ID, BaseTypeId.CMIS_DOCUMENT.value());
        properties.put(PropertyIds.NAME, "hello");
        
        Document doc = this.scratchFolder.createDocument(properties, contentStream, VersioningState.MAJOR);
        
        ContentStream retrieved =  doc.getContentStream("0", BigInteger.valueOf(5), BigInteger.valueOf(5));
        System.out.println("streamlength: " + doc.getContentStreamLength());
	}
{code}

The test only retrieve from position 5, length 5 of contentstream, but the {{doc.getContentStreamlength()}}
actually return 50 (the length of whole ocntent).
On server side implmentation, we actually set the length to 5:
ContentStream [filename=hello.txt, length=5, MIME type=text/plain, has stream=true][extensions=null]

I traced the client.bindings.spi.atompub.ObjectServiceImple, the response header is:
{noformat}
{cache-control=[private, max-age=0], content-type=[text/plain], null=[HTTP/1.1 206 Partial
Content], transfer-encoding=[chunked], content-disposition=[attachment; filename=hello.txt],
content-language=[en-US], server=[Apache-Chemistry-OpenCMIS/1.0.0-SNAPSHOT], date=[Thu, 09
Apr 2015 06:43:24 GMT], content-range=[bytes 5-9/*]}
{noformat}

The code set the length using {{result.setLength(resp.getContentLength());}}

Is this a bug?
