It never hurts to start a ticket. Especially if you have patches. Thinking about it more, it seems like the Erlang side is gonna be looking for that start signal before it will send a row. We'll need to design a dont-start signal, so that it can get a row without sending headers. > On Sun, Sep 27, 2009 at 12:06 PM, Paul Davis > <paul.joseph.da...@gmail.com> wrote: >> On Sun, Sep 27, 2009 at 1:04 PM, Zachary Zolton >> <zachary.zol...@gmail.com> wrote: >>> Hey guys, newb question for you: the make script concatenates all the >>> /share/server/*.js scripts into main.js, right? >>> >> >> yepper. >> >>> I'm still trying to figure this stuff out... >>> >>> On Sat, Sep 26, 2009 at 11:35 PM, Zachary Zolton >>> <zachary.zol...@gmail.com> wrote: >>>> I'll start studying the query_server_spec.rb script; I think I might >>>> be able to handle this in JavaScript... >>>> >>>> On Sat, Sep 26, 2009 at 11:22 PM, Chris Anderson <jch...@apache.org> wrote: >>>>> On Sat, Sep 26, 2009 at 8:57 PM, Paul Davis <paul.joseph.da...@gmail.com> >>>>> wrote: >>>>>> its been awhile since i studied the Erlang side of this, but IIRC, >>>>>> once getRow() returns, the response has started which means that you >>>>>> can't send a redirect.
