Redirect from _list function?
Hello,
Should I be able to do a redirect from a _list function?
I ask because I've tried defining the following _list function:
function(head, req) {
return {
'code': 301,
'headers': { 'Location': 'http://www.google.com/' }
};
}
And, here's what happens when I try to hit it:
$ curl -i 'http://localhost:5984/db/_design/ddoc/_list/test-redirect/some-view?key=%22foo%22'
HTTP/1.1 200 OK
Vary: Accept
Transfer-Encoding: chunked
Server: CouchDB/0.11.0a9fd42dc1-git (Erlang OTP/R12B)
Etag: "46014W5JDRLKZF5SECP2D44YH"
Date: Thu, 24 Sep 2009 22:23:14 GMT
Content-Type: application/json
curl: (56) Received problem 2 in the chunky parser
Obviously, this does not look like a redirect. :^( Do I seem to be
doing anything wrong here?
Thanks!
Zach

Hm... I'm gonna have to learn more about list functions work to

Bit tired here but two thoughts. Theoretically returning a 304 should
work fine I think. The question is what mutation happens when
processing the _list. I'd suggest taking a glance at render.js to see
if maybe you're getting caught by a corner case.

(My sincere apologies—I didn't mean to sound impatient! Rather, I was
just trying to clarify my question, which I can now sum up as: am I
doing something fundamentally wrong or is CouchDB acting funny?)
Now, onto Jan's suggestion, I've tried setting Transfer-Encoding to
both null and 'foo', but the response always seems to have chunked for
the header value. So my initial guess is that I'm unable to override
it for some reason...
I couldn't determine any other values from the spec worth trying:
http://tools.ietf.org/html/rfc2616#section-14.41
Assuming that this is a bug, I've created the following on JIRA:
https://issues.apache.org/jira/browse/COUCHDB-513

The chunky-parser error message occurs when curl expects a chunked
HTTP response body and then doesn't get one. Your reply sends the
`Transfer-Encoding: chunked` header, so curl expects to see a body
chunked according to RFC2616 and it doesn't get one.
Obviously, a redirect shouldn't have a response body or even the
`Transfer-Encoding` header to begin with. You could try overriding
the header, but maybe CouchDB inserts it unconditional in which
case we should fix that, if you find out you can't override the
`Transfer-Encoding` header, can you file a bug report?
Cheers

So, can anyone give a reason why this _list function shouldn't work?

I've posted a patch from my experiments to the ticket. I'm thinking
this'll require some Erlang-fu...?

I'm into getting this to happen too. I barely have time, but I can advise.
It wouldn't hurt to post a patch of what you tried, even if it didn;t
work, as it will let other know which code you are digging into.

Re: Redirect from _list function?
Posted by Zachary Zolton <za...@gmail.com>.
Guys,
I've started a ticket for this:
https://issues.apache.org/jira/browse/COUCHDB-514
I don't know what level of effort would be required to fix this, or if
this is even compatible with the current view server protocol. I'm
motivated to solve this, but I'd need some coaching from someone with
more knowledge of CouchDB view server internals.
Cheers,
Zach

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.

Hmm... I can't do anything that doesn't result in a view server timeout. (^_-)
Shall I open an issue? I can discuss what I tried, as well...

Hey guys, newb question for you: the make script concatenates all the
/share/server/*.js scripts into main.js, right?
I'm still trying to figure this stuff out...

Yes I think it would be a simple patch, once you understand the
entrails of the _list system. You should read the query_server_spec.rb
to see what gets sent by the query server on first getRow() call.
It may be that this patch can be accomplished just in the javascript side.

Re: Redirect from _list function?
Posted by Paul Davis <pa...@gmail.com>.
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. To get it working proper then would require a
bit of a patch to wait on starting the response until the first output
from the _list function.

Fwd: Redirect from _list function?
Posted by Zachary Zolton <za...@gmail.com>.
Hey guys,
I need to find a way to do a redirect from a _list function after
calling the getRow() function. After looking at render.js for a while
I can't see how to solve this without at least adding to the API.
Basically, I think that calling getRow() shouldn't cause the view
server to send the headers (or awaiting chunks) unless we've already
called send() or something like that. That way, we can return from the
_list function after iterating to the first row that should redirect.
(I'm not sure if this is a breaking change from the current semantics,
however...)
Would greatly appreciate a little guidance on how to attack this!
Cheers,
Zach

Yes... The headers are sent when the first getRow is called. Fixing
this is definitely something I'd support.

Okay, I've update this section to differentiate between the 0.9 and

Now, I'm feeling that the Other Fun Things section could use a bit of

Hi Zach,
Try this instead:
function(head, req) {
start({code:301, headers: { 'Location': 'http://
www.google.com/' }});
}
