Re: Spec's not being checked on macro expansion

Hi Ed, I could not reproduce the behavior you described with Leiningen. Here is my test script: https://gist.github.com/stuartsierra/ca2b9bd7072224e099beb8b95b49b69c This issue might be caused by some pre-compiled files on the classpath when you run `lein test`. Since macros are evaluated durin

Re: topic-fn returning more than one topic

Hi Oded, I think you would have to implement your own message-routing to achieve this. Create one "output" mult for each topic, subscribe to them with `tap`, and route the messages to the channels as they arrive. Pseudo-code: (go-loop [] (when-some [message (! topic-ch message))) This is qui

Hi Istvan, I often work with multiple source directories by temporarily adding them to the :source-paths in a Leiningen profile

Did you try this: (jdbc/with-db-connection [conn config/db] (.setAutoCommit (jdbc/db-find-connection conn) false) (into [] (take 2) (jdbc/reducible-query conn query {:fetch-size 500})) (I don’t have your sort of data set to test on with PostgreSQL) Sent from Mail for Windows 10

[ANN] clojure.java.jdbc 0.7.0 Beta 4

[org.clojure/java.jdbc “0.7.0-beta4”] is available! It fixes reflection warnings, it passes opts correctly from reducible-query to the underlying prepare-statement, and it completes the optional specs (compared to Beta 1), as well as correctly supporting the docstring contract of reduce. Sean C
