if you're interested in preserving more information, you could also look at rewrite-clj

Okay, thanks for the tip! I need to read an external .clj file and get metadata, like clojure doc strings, back. I guess that library will solve that. I will have a look.

In this case you can also use clj-kondo

@tengstrand Example:

$ clojure -M:clj-kondo/dev --lint src/babashka/main.clj --config '{:output {:format :edn :analysis true}}' > /tmp/analysis.edn
$ cat /tmp/analysis.edn | jet --pretty --func '(fn [json] (->> json :analysis :var-definitions (filter :doc) (map (juxt :ns :name :doc))))'
([babashka.main
  musl?
  "Captured at compile time, to know if we are running inside a\n  statically compiled executable with musl."])

(so here it finds only one var with a docstring in the babashka/main.clj file)

if you have any questions about how to use this, let me know

Sure, will have a look at it later. Thanks.

I remember using ant back in.... 2010 or 2011? I believe that was the "official" way of managing a clojure project, but how you obtained the dependencies was up to you - mostly by downloading jars and figuring out the classpath

The common approach is clojure -M foo.clj

Yeah, looking at some early commits to Compojure, it suggests using ant to install the dependencies: https://github.com/weavejester/compojure/tree/0.3

I used (and all the contrib libs still use) the clojure-maven-plugin with Maven

I used maven as a build tool / test runner, swank to connect to a repl and some custom shell scripts for some more specialised jobs. It worked great for years, and I didn't actually migrate to lein till something like 2015. I was working at a startup and switching build tools just never got to the top of our priority list. But I came from a java background and was already comfortable with mvn.

We would generally aot the things we wanted to run, and java -jar path-to-uber.jar

I used a Makefile, but I don't entirely recall the details

Thank you for all the responses!

question is about non-heap, not heap

check for direct buffers being allocated

also, how are you determining that non-heap is growing?

you can use visualvm or https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#getAllStackTraces() to get a count of the active threads, the stack of each counts as non-heap memory

Thanks for the quick replies. https://metrics-clojure.readthedocs.io/en/latest/jvm.html is being used to monitor the memory.

Can't claim much experience, but there's this: https://github.com/metabase/saml20-clj

@U025VPS4R7U If you haven’t already, you might have more chance of an answer in either #datomic or #ions-aws I suspect

Also, I believe Cognitect/Nubank do most of their actual support via https://forum.datomic.com/

Great, thanks for the suggestion! I missed finding those channels when I searched earlier.
