test suite failing on views

[Alex Chapman <ch...@gmail.com>]

Hi,

I'm using couchdb-0.8.0-incubating, and I'm getting errors every time
I try to run a view. For example, the first test in the test suite
fails with this message in the browser:

Exception raised: {"error":"epipe","reason":"[{erlang,port_command,\n
[#Port<0.177>,\n [91,\n \"\\\"add_fun\\\"\",\n 44,\n \"\\\"(function
(doc) {if (doc.a == 4) {emit(null, doc.b);}})\\\"\",\n 93,\n 10]]},\n
{couch_query_servers,writeline,2},\n {couch_query_servers,prompt,2},\n
{couch_query_servers,'-start_doc_map/2-fun-0-',2},\n
{lists,foreach,2},\n {couch_query_servers,start_doc_map,2},\n
{couch_view,view_compute,2},\n {couch_view,update_group,1}]"}

At the same time, couchdb logs the following:

[info] [<0.67.0>] 127.0.0.1 - - "POST /test_suite_db/_temp_view" 500

I'm not sure whether this helps, but I tried to see whether the
problem was in the javascript interpreter:

/usr/local/share/couchdb/server$ couchjs main.js
["add_fun","function(doc){emit(null,doc);}"]
true
["add_fun",44,"(function (doc) {if (doc.a == 4) {emit(null, doc.b);}})",93,10]
{"error": "compilation_error","reason": "expression does not eval to a
function. (44)"}

I'm just about out of ideas. My next step is to learn erlang and start
debugging, but I'd prefer not to do that right now.

Can anyone help?

Thanks,

Alex

Thanks Jan, but this doesn't really fix my problem. I only put that
line in because that's what couchdb seemed to be sending to couchjs.
The problem is not with the javascript used, because even the
javascript in the test suite fails.

Do not wrap your functions in parenthesis.

function(doc) { ... } instead of (function(doc) { ... }
