Clojurians Log v2

Hi @karol.wojcik! Awesome, thanks for sharing. At the moment I'm just exploring.

It's important to say that the issue is that the terminal blocks 😅

does d/connect make a non-daemon thread?

and are you calling it at the top level of your code like

(def conn (d/connect))

because my first guess is that you are making AOT hang

Yes I'm calling it like you say

How should it be done?

Do you know where can I find some docs about it?

so this isn’t about holy lambda so much as its about AOT in general

i would call it like this

(defn connect-to-datomic 
  []
  (d/connect opts))

(defn start-system
  []
  {:datomic (connect-to-datomic)})

;; then in your entrypoint
(... (let [system (start-system!)]
       (... do code ...)
       // potentially clean up beteen invocations ...)

but the “lazy” solution for you to get your stuff working is just

(def conn (delay (d/connect)))

and then replace your usages of conn with @conn

Works just as you say, thanks for your help!

@emccue @carloshernandez2.1b very good explanation. Will NuBank use holy-lambda in production?

Btw hl:compile does nothing special. It's an alias for the command that compiles a project with an AOT, since uberjar happens locally via depstar now. The reason hl:compile exists is to inform hl:native:conf how the project should be compiled for the GraalVM agent. Planning to move to tools.build in the next release.
