Paul Joseph Davis commented on COUCHDB-514:
-------------------------------------------
Ohhhh.
The reason that Zachary's patch won't work is that the Erlang side is waiting
for the start before sending the first row. The "getRow()" style API in
JavaScript is still bound by the serialized enforcement that the Erlang side
does. Sadly that means the patch is more involved than I had initially thought.
For interested parties, the fix for this is in reworking how
couch_httpd_show.erl uses the btree fold function. Basically, in
couch_httpd_show:start_list_resp/5 the proper thing would be to just send the
head info and defer the response building till later in the iteration process
when render_list_row is called.
