Subject test suite failing on views
Date Wed, 16 Jul 2008 05:05:04 GMT
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
