clutch working on local couchdb; fails on cloudant

[Walter Babic]

Hello,

I am working with clutch:

[com.ashafa/clutch "0.4.0-SNAPSHOT"]

and a local version of couchDB and a version on Cloudant.

Same code works locally but not with Cloudant:

ts.core=> (get-docs local-db {:keys [wb]})

({:id "b6e...88b", :key "wb*@*.com", :value {:_id "b6e...88b", :_rev "13-f9...09", ... , :email "wb*@*.com"}})

ts.core=> (get-docs prod-db {:keys [wb]})

ExceptionInfo clj-http: status 500  clj-http.client/wrap-exceptions/fn--946 (client.clj:86) 

where 

ts.core=> local-db

#cemerick.url.URL{:protocol "http", :username "wbabic", :password "*******", :host "localhost", :port 5984, :path "/ts", :query nil, :anchor nil}

ts.core=> prod-db

#cemerick.url.URL{:protocol "http", :username "wbabic", :password "********", :host "wbabic.cloudant.com", :port 80, :path "/travelingsirens", :query nil, :anchor nil}

(defn get-docs

  [db keys]

  (clutch/with-db db (clutch/get-view "profile" "email" keys)))

and

ts.core=> wb

"wb*@*.com"

prod-db url seem correct since get-database works:

ts.core=> (get-database local-db)

#cemerick.url.URL{:protocol "http", :username "wbabic", :password "********", :host "localhost", :port 5984, :path "/ts", :query nil, ... :doc_count 3}

ts.core=> (get-database prod-db)

#cemerick.url.URL{:protocol "http", :username "wbabic", :password "********", :host "wbabic.cloudant.com", :port 80, :path "/travelingsirens", :query nil,.... :doc_count 4}

(defn get-database [db]

  (clutch/get-database db))

Any reasons why it does not work on Cloudant? Any ideas on how to see whats going on?

Thanks,

Walter

Hi Walter - I was trying to reason through some of this and noticed
that you didn't post any info on the view definition. Any chance you
can do that? Have you verified that it exists on Cloudant and can be
accessed / queried via other means?

Best,

Michael

[Walter Babic]

Yes, thanks, Michael,  good suggestion.

Here is what I found using cURL:

bash-3.2$  curl -X GET http://wbabic:********@localhost:5984/ts/_design/profile/_view/email

{"total_rows":2,"offset":0,"rows":[

  data looks right

]}

bash-3.2$  curl -X GET http://wbabic:********@wbabic.cloudant.com/travelingsirens/_design/profile/_view/email

{"error":"compilation_error","reason":"Expression does not eval to a function. ((new String(\"(function () {function b(a){throw 

I will try reloading the view. 

Thanks,

Walter

[Walter Babic]

Here is the view, which was working, I thought anyway. After reloading locally, I get the same error. Consistent, at least. It has been a while since I had first loaded the view locally and has been working since, until I just reloaded. Broken in dev, I can deal with. Working in dev but not prod is harder. So does the view look okay?

Walter, you don't happen to have any AOT compilation in your project, do you? If you accidentally AOT compile the clojurescript compiler view creation will break. To fix this, I had to to add :skip-aot metadata to my :main entry in project.clj. For example,

:main ^{:skip-aot true} paddleguru.server

Hope that helps,

Sam

(Too brief? Here's why! http://emailcharter.org)

[Walter Babic]

I added 

                 [org.clojure/clojurescript "0.0-1011" :optional true

                  :exclusions [com.google.code.findbugs/jsr305

                               com.googlecode.jarjar/jarjar

                               junit

                               org.apache.ant/ant

                               org.json/json

                               org.mozilla/rhino]]

the exclusions, as in clutch/project.clj and now it works.

Previously, I only had 

                 [org.clojure/clojurescript "0.0-1011"]

So it works now, although I am not totally sure why,

thanks for the help.

Walter

Hi Walter,

Sorry for the difficulties you ran into.  The exclusions in the clutch project shouldn't be required for cljs views to be compiled properly, though.  The fact that they worked well locally (presumably with the exclusion-less cljs dependency) would seem to confirm that in your case.

The broken view code you pasted is woefully incomplete.  A cljs view is likely to be ~40K or more, not just a few lines of JavaScript.  I'm thinking that the Closure compiler wasn't able to find the base ClojureScript files, leading to the incomplete result.  IIRC, I've had the same problem in one or two circumstances; clearing the 'out' directory (a temporary work space for the ClojureScript and Closure compilers) has resolved the problem.  If you can try doing this with the exclusion-less cljs dependency, that'd be great.

Thanks,

- Chas

Chas,

I tried again with no exclusions in the cljs dependency: [org.clojure/clojurescript "0.0-1011"] and it worked both locally and on Cloudant. 

Thanks,

Walter.

Yes, that was just a proof of concept. I have just started ch 15 of Clojure Programming. Looks like there os some good stuff there. I have been enjoying the book so far, thanks for making that available.

Sorry, that wasn't clear. :-)

I wasn't saying that you had missed anything; I was saying that the JavaScript that results from (what should be) automatic core.cljs compilation didn't appear to be in the generated code.

Glad you're liking the book, though!
