@U01RXDR9F4M This is the time you can take the list of libraries you're using and post them all 😄

com.cognitect.aws/*

io.pedestal/pedestal.log            {:mvn/version "0.5.9"}
ch.qos.logback/logback-classic      {:mvn/version "1.2.5"}
com.fasterxml.woodstox/woodstox-core {:mvn/version "6.2.6"}
com.jcraft/jsch                {:mvn/version "0.1.55"}
clj-http/clj-http                   {:mvn/version "3.12.3"}
org.apache.cxf/cxf-core              {:mvn/version "3.4.4"}
io.xapix/paos                        {:mvn/version "0.2.5"}

Most of my lambdas are on HL 0.2.3. The first 4 entries I’ve configured to run on HL 0.5.0 with the dev graalvm which currently uses the 21.3.x line and forces build-time config.

"--initialize-at-build-time=com.fasterxml.jackson,org.eclipse.jetty,ch.qos.logback,javax.xml.namespace.QName,org.slf4j.LoggerFactory,org.slf4j.impl.StaticLoggerBinder,com.ctc.wstx,javax.xml.stream.FactoryFinder,io.opentracing.util.GlobalTracer,com.sun.org.apache.xerces.internal,javax.xml.parsers.FactoryFinder,com.sun.xml.internal.stream.util.ThreadLocalBufferAllocator,jdk.xml.internal.JdkXmlUtils"
                                                    

The latter 5 (woodstox and onwards) all gave me pain with getting native build to run correctly and needed careful native/agent code to coax the right build

to get pedestal logging to build at all on graalvm, I had to disable metrics recording using the follow parameter to graalvm

;; Disable JMX metrics in Pedestal logging (GraalVM build fails, plus JMX metrics are not useful in Lambda)
"-Dio.pedestal.log.defaultMetricsRecorder=nil"

Thanks. This is already a lot to be patched 😄

No worries, and thank you for this!

Which one is the most important @U01RXDR9F4M

the first list I posted is in order of importance to me

clj-easy currently adds cognitect to the Clojure namespaces supplied to the build time parameter, but I had to also add org.eclipse.jetty to the build time list to prevent those scary runtime stack traces we went though last week

yep, we can fix this by making a clj-easy config for it in https://github.com/clj-easy/graal-config

@U01RXDR9F4M whas is necessary for pedestal log to work? Build is successful, but I'm not seeing any logs

Oh it probably requires slf4j implementation

Forgotten how good logging in java is 😄

Pure love for the idea of "let's do a facade for everything guys, ok?" 😂

Yeah. Got it working

@U01RXDR9F4M how to trigger this metrics recorder?

not sure how to explicitly trigger the metrics recorder, as far as I’m aware, it’s just “there” and initialises by default

to that end, it would be triggered by using the logger, I guess

What facade do you using for loggin?

pedestal -> slf4j then using logback for the logger implementation

pop the above in your resources

another way to break graalvm build is to specify config scanning in logback.xml. I’ll post an example in a sec

<configuration scan="true" scanPeriod="5 seconds"> <!-- scan is handy for REPL sessions, but fatal to GraalVM native builds :-) -->

The following deps and the logback.xml file in resources should be enough to get you logging.

io.pedestal/pedestal.log             {:mvn/version "0.5.9"}
ch.qos.logback/logback-classic       {:mvn/version "1.2.5"}

(:require
    [io.pedestal.log :as log])

(log/error :in 'my-fn :message "this is a message")

(sorry if that’s teaching granny to suck eggs)

Out of curiosity why are you not using slf4j simple?

I mean of course i will provide patchem for all of those but still im genuinely curious

if these deps all worked (which I haven’t tried, will do so in a few weeks) Clerk should be runnable in native image

org.clojure/java.classpath {:mvn/version "1.0.0"}
org.clojure/tools.analyzer.jvm {:mvn/version "1.1.0"}
org.clojure/tools.deps.alpha {:mvn/version "0.11.905"}
weavejester/dependency {:mvn/version "0.2.1"}
funcool/datoteka {:mvn/version "1.0.0"}
com.nextjournal/beholder {:mvn/version "1.0.0"}
mvxcvi/multihash {:mvn/version "2.0.3"}
lambdaisland/uri {:mvn/version "1.4.70"}
arrowic/arrowic {:mvn/version "0.1.1"}
rewrite-clj/rewrite-clj {:mvn/version "0.6.1"}

> Out of curiosity why are you not using slf4j simple? Just familiarity with Logback. I’ll try SimpleLogger as it’s probably more lightweight. For instance, it would do away with a load of XML references.

@U01RXDR9F4M simpleogger is easy to bake with Graal. Just include simple logger in initialize-at-build-time

@UJ1339K2B what are the exact build time parameters you’re using for SimpleLogger? It took the following for a simple lambda with only a log statement to work:

"--initialize-at-build-time=com.fasterxml.jackson,javax.xml.parsers.FactoryFinder,com.sun.org.apache.xerces.internal,jdk.xml.internal.JdkXmlUtils"

ps - I’m using the dev graalvm image

Args=--initialize-at-build-time=org.slf4j.LoggerFactory \
     --initialize-at-build-time=org.slf4j.impl.StaticLoggerBinder \
     --initialize-at-build-time=org.slf4j.impl.SimpleLogger

@U01RXDR9F4M

@U5H74UNSF How clerk works? Isn't it dynamically loads arbitrary classes at run time?

@UJ1339K2B I take it that’s without pedestal logging?

Yeah

But it works with pedestal logging

Although don't know how to trigger metrics

https://github.com/clj-easy/graal-config/tree/master/config/org.slf4j/slf4j-simple

https://github.com/clj-easy/graal-config/blob/master/config/org.slf4j/slf4j-simple/example/src/example/core.clj

I’ll see if I can send a repro, but it won’t be until tomorrow

You mean for metrics? 😄
