Julien Coloos commented on HTTPCORE-573:
----------------------------------------

Small patch to take into account 'count' when reading data from the internal 
buffer.

> FileContentDecoder don't always enforce the maximum number of bytes to 
> transfer

> The FileContentDecoder.transfer function has the 'count' parameter indicating 
> the maximum number of bytes to transfer.
>  Implementations (LengthDelimitedDecoder and IdentityDecoder) don't respect 
> this parameter when getting the data from the internal buffer: in practice 
> the whole buffer content is transferred, thus the actual number of bytes 
> transferred may exceed the maximum requested by caller.
> Since the way data are read from the buffer can be limited, it is possible to 
> respect the requested 'count'.
