Stéphane Alnet commented on COUCHDB-1155:
-----------------------------------------
Although you can't currently override the Etag you can modify it:
"lists": {
"test": "(function(){start({headers:{Etag:'foo'}}); send('');})"
}
GET /bar/_design/foo/_list/test/test
HTTP/1.1 200 OK
Vary: Accept
Transfer-Encoding: chunked
Server: CouchDB/1.2.0 (Erlang OTP/R15B01)
Etag: foo, "4SNNDV6U28X8Z7TXTQURJAMPT"
Date: Wed, 03 Oct 2012 08:20:14 GMT
Content-Type: application/json
So the Etag provided by Javascript is pre-pended to the CouchDB-generated Etag,
which should be sufficient?
> Etag send by list function does not depend on userCtx

> Key: COUCHDB-1155
> URL: https://issues.apache.org/jira/browse/COUCHDB-1155
> Project: CouchDB
> Issue Type: Bug
> Components: HTTP Interface
> Affects Versions: 1.0.2
> Reporter: Johannes J. Schmidt
> Assignee: Randall Leeds
>
> List functions should send a different Etag when requested by different users.
> The following curl session shows identical Etags for different users. CouchDB
> must not be in admin party mode.
> PROTOCOL=http
> DOMAIN="127.0.0.1:5984"
> DB=testdb
> # admin credentials for db creation
> ADMIN=admin:secure
> # this user must have an empty roles array
> USER=user:secure
> curl -XDELETE $PROTOCOL://$ADMIN@$DOMAIN/$DB
> curl -XPUT $PROTOCOL://$ADMIN@$DOMAIN/$DB
> curl -XPUT $PROTOCOL://$ADMIN@$DOMAIN/$DB/foo -d '{"count":1}'
> curl -XPUT $PROTOCOL://$ADMIN@$DOMAIN/$DB/_design/foo -d '{ "views": { "bar":
> { "map": "function(doc) { emit(doc._id, null); }" } }, "lists": { "bar":
> "function(head, req) { return req.userCtx.name || \"anonymous\" }" }}'
> curl -s $PROTOCOL://$DOMAIN/$DB/_design/foo/_list/bar/bar --head | grep Etag
> curl -s $PROTOCOL://$USER@$DOMAIN/$DB/_design/foo/_list/bar/bar --head | grep
> Etag
> #=> Etag: "A1NKHA0935KMCSHFSK94EHZNL"
> #=> Etag: "A1NKHA0935KMCSHFSK94EHZNL"
> This issue is important for standalone CouchDB applications which use list
> functions depending on the user context, eg. showing a login button or
> username.
> regards
> Johannes
> PS: I tried to write a javascript test case but this issue can only be
> reproduced if the server is not in admin party mode, which the test suite
> requires. I am not so familar with those tests to temporarily change the
> admin party.
