Enable Erlang for views?

[Zachary Zolton <za...@gmail.com>]

Guys,

I noticed that the test suite creates a design document with an Erlang
view, however I can't execute it from curl.

$ curl http://localhost:5984/test_suite_db/_design/erlview/_view/simple_view
{"error":"unknown_query_language","reason":"erlang"}

Are we supposed to be able to map/reduce our docs in Erlang?


Cheers,

Zach


PS. I'm using CouchDB 0.10 FWIW

PPS. Yes, I found this thread http://is.gd/4r6oG but erlview doesn't
look like it's been touched in quite a while...

Not sure I follow. I meant check that the test exists to make sure
that erlang views are in the running CouchDB node.

aren't those views in the test suite temporary?

Ah, my launchd setup is apparently borked, cuz stop/start'ing the
server didn't work, but rebooting my system did. Drat!

Well anyways, it does seem to be working!

Thanks again,
Zach

Zachary,

Did you restart CouchDB after making that change? Also, can you double
check that there's an erlang_views.js in your Futon's Test suite? I'm
pretty sure that's in 0.10.0.

Do you have a newline after this last line?

Re: Enable Erlang for views?

[Zachary Zolton <za...@gmail.com>]

Hm... Not so fast, I put the following in my local.ini:

[native_query_servers]
erlang = {couch_native_process, start_link, []}

But now when I try it, I'm still getting the error:

$ curl localhost:5984/test_suite_db/_design/erlview/_view/simple_view
{"error":"unknown_query_language","reason":"erlang"}

Anything else I should need to configure?

Understood—my couch doesn't accept design docs from outside sources,
so this should be "safe enough" for my uses... Thanks!

Erlang views are disabled by default because they allow arbitrary code
execution in the server process. To enable them add a section to your
local.ini like:

[native_query_servers]
erlang = {couch_native_process, start_link, []}

HTH,
