47498 - OnDataAvailable() is never called again if data is not read from the Stream

Status: VERIFIED FIXED

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Andrew Kimpton]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; DigExt)
BuildID:    2000073008

A Plugin handling a Stream of incoming data should be able to return NS_OK from 
OnDataAvailable() without actually removing any data from the Stream (since 
it's internal buffers are full) and be assured that OnDataAvailable() will be 
called again in the future.

Currently if you return from OnDataAvailable() without reading from the stream 
Mozilla never calls OnDataAvailable() again.

Reproducible: Always

Without fixing this implementing any plugin with 'streaming' behaviour is much 
more complicated. This new behaviour is also very different from what happens 
in Netscape 4 using NPP_WriteReady() and NPP_Write().

Not a Netscape 6 RTM blocker. FUTURE. This bug has been marked Future because
the Netscape engineer it is assigned to is overburdened.
