Hi,
I am experiencing some problems with update functions which I use to
create documents in CouchDB when they are using require() to load a
common library. It seems that after publishing the design document then
the first update function to be called works well but any subsequent
ones do not call require(). With the log() call in the require I see
this appear in the call to the first update but it does not appear with
any others, they print a stack trace such as:
[Thu, 12 Dec 2013 13:20:55 GMT] [error] [<0.6458.0>] httpd 500 error
response:
{"error":"render_error","reason":"function raised error: (new
ReferenceError(\"docUtil is not defined\", \"updates.template\", 54))
stacktrace: (null,[object Object])@updates.template:54
runUpdate(<<<body of update function>>>),[object Object],[object
Array])@/usr/local/share/couchdb/server/main.js:1033
(\"_design/provision\",[object Array],[object
Array])@/usr/local/share/couchdb/server/main.js:1517
()@/usr/local/share/couchdb/server/main.js:1562
@/usr/local/share/couchdb/server/main.js:1573
"}
As far as I can tell by require()d code is ok since the same structure
is working for other things. What it seems to me is that it is loaded
by CouchDB for the first update function and is then recorded as loaded
but a second update function needing the same code has its require
ignored but cannot reference the in memory copy produce by the require
from the first update.
I have tested versions CouchDB 1.3.1, 1.4.0 and 1.5.0 all with the same
behaviour. I am running on Ubuntu precise with esl-erlang 1:16.b.3-1.
Any suggestions on where to look next?
Thanks,
James
As an example:
The updates are all of the form:
function(doc, req) {
require('views/lib/docUtil');
if(!doc) {
doc = {some: defaults}
}
// some other code
doc.meta = docUtil.metaCreate(req);
return([doc, JSON.stringify(doc, undefined, 2)]);
}
views/lin/docUtil is similar too:
(function(global) {
var _metaCreate = function(req) {
...
};
var _metaModify = function(req) {
...
};
log('docUtil loaded')
global.docUtil = {
metaCreate = _metaCreate,
metaModify = metaModify
};
})(exports.docUtil = this)
