ZnLineReader set limit when reading a header

When using the Phriak client I infrequently want to access all the keys
in a bucket. When I do I sometimes get the ZnLineTooLong error because
Riak returns the list of keys in the response header. Is there a way to
set the maximum line length for the headers on a per request basis so I
can change how the ZnClient operates while running Riak operations?

No, there currently is no per-request way to set the ZnConstants class>>#maximumLineLength.

You can only override that method, it is just an intentional resource protection limit, making it 64k or so won't hurt (apart from allocating larger buffers).

I guess I could make it globally settable.

You're the first one hitting that limit ;-)

It looks like the server they use internally (Mochiweb) limits them to
8k. So I can just override ZnContants class>>#maximumLineLength in my
image to 8200 and be set.
