Clojurians Log v2

I just installed a portkey function via (pk/mount): I get error:

{"errorMessage":"Error loading class portkey.LambdaStub: clojure/lang/IFn","errorType":"java.lang.NoClassDefFoundError"}

(defn flatter []
  (str "hello world"))

(pk/mount! flatter "/hello")

Yes

You can download it on the aws interface

But you won’t learn anything as it’s bytecode

Weird, on the AWs interface, I see a "clj-hello" (which is some other functikn I manually uploaded), but I don' see the "flatter / hello" function.

I want to open up the jar/zind see if Clojure/IFN .class is somewhere there.

You sure you are in the right region ?

I'm an idiot.

Was in wrong region.

Not an idiot, this happen ;-)

Do you still mount it from boot ?

Yeah, I have never tried mounting from lein.

cgrand sent in a patch, so I assumed mounting from boot works ....

Because lambdastub call the handler that aws is waiting for, it should be present

Oh

I had some personnal stuff last week so I won’t be able to work on portkey for an other week but even if there are still bugs, your function is working for me

100% sure

Awesome, thanks!

I will take this opportunity to to build a Cryptic-AWS-Error-Msg -> how-to-fix-it map 🙂

I will be back on business on Tuesday

Back from US ;-)?

@qqq that’s something that can be upgrade, how to shorten the error-message feedback loop

I downloaded my package (took a while to figure out the GUI). I run:

find . | grep Lambda
./com/amazonaws/services/lambda/runtime/LambdaLogger.class
./portkey/LambdaStub.class

find clojure
clojure
clojure/java
clojure/java/api
clojure/java/api/Clojure.class

I'm expecting to see clojure/foobar/IFn.class

Have you try to reboot your repl and re-mount it ?

I will try that right now.

Almost home. Enjoying traffic jams due to the start of fall holidays.

Hehe

@baptiste-from-paris: same issue; will now see if I can get mount to work via a lein repl

Ok, if it doesn’t pastebin your code and I’ll try

lein repl

weirdness; Lein gets an ouroboros NullPointerException ?

here is my project.clj:

cat project.clj 
(defproject foobar "0.1.0-SNAPSHOT"
 :description "FIXME: write description"
 :url "<http://example.com/FIXME>"
 :license {:name "Eclipse Public License"
 :url "<http://www.eclipse.org/legal/epl-v10.html>"}
 :dependencies [[org.clojure/clojure "1.9.0-beta2"]
 [portkey "0.1.0-SNAPSHOT"] ])

I'm going to go nuke ~/.m2 and retry all this.

Ok, let me try (and take a break from my bordeaux wine)

hmm, I just did a git pull, ouroboros was updated, perhaps I am facing an older bug

success: from lein repl, I got a clj function to mount 🙂

I don't knowif this issue is boot vs lein or "old code vs doing a git pull"

but once ~/.m2 is repopulated, I will test in boot repl

Oh nice !

I think the boot repl is tree shaking too much.

lein repl -- uploaded a 4.5 MB zip

boot repl -- uploladed a 1.5MB zip (earlier) and a 300k zip (now)

personnaly I rarely have mounting problem, it’s more error once mounted

so it's apparently shaking the tree soo hard clojure function classes are being shaken off

@qqq does not sound satisfying, I think Clojure itself is around 3MB

find lein | grep -i clojure ; echo "==" ; find boot | grep -i clojure
lein/clojure
lein/clojure/java
lein/clojure/java/api
lein/clojure/java/api/Clojure.class
lein/lib/clojure-1.9.0-beta2.jar
==
boot/clojure
boot/clojure/java
boot/clojure/java/api
boot/clojure/java/api/Clojure.class

The lein version includes clojure-...-.jar ; the boot version somehow does not.

I'm half tempted now to add the jar file into the boot version, and manually upload it 🙂

okay, I got the boot version to work

by copying over /lein-version/lib to /boot-version/lib , recreating the zip, and uploading it

I'm filing an issue on github.

nice !

@cgrand: ^-- welcome home gift for you 🙂

@baptiste-from-paris: thanks for the tip on downloading from aws // could not have debugged this without that

Ah gréât !

By the way, I can’t verify right now but I am pretty sure that you can download it with the api

@cgrand @baptiste-from-paris: i realize portkey is open source software with no SLA and the volunterr devs have lives of their own -- is there some hack I can use to get around this in boot? This is on the critical path of my work.

I just switched from boot to lein; this is no longer blocking me. 🙂
