Clojurians Log v2

My coworker and I are experiencing this bug: https://github.com/thheller/shadow-cljs/issues/877

We’ve tried deleting .shadow-cljs, target and compiled js. We’ve upgraded to shadow-cljs 2.13.0 as well

We’ve tried running a new shell as well

Any ideas. Thheller expains some incompatibility with version of CLJS and shadow. We’re not specifying CLJS in our deps as afaik, shadow-cljs pull them in with the correct version.

I had to update any deps using goog.isBoolean.

I started getting this error

Execution error (ClassNotFoundException) at jdk.internal.loader.BuiltinClassLoader/loadClass (BuiltinClassLoader.java:581).
jdk.vm.ci.services.Services

no clue, never seen that error before. did you by any chance change your JVM installation at the same time?

unlikely to be anything in shadow-cljs, more likely something else in your setup

Didn't change my JVM. I'm using openjdk version "15.0.1" 2020-10-20 on macOS.

But I also tried with openjdk version "11.0.10" 2021-01-19 without luck.

It's loooong file, but this might help

It was generated by the Clojure CLI.

yeah dunno. the graal-js engine has been in use for a while now (definitely long before 2.12.5) so I don't know why you'd be getting that error now

always helps to sort out your dependency conflicts if you use project.clj or deps.edn

might just be a classpath issue with a missing dependency or so

I'm on 2.12.5, so let me try to upgrade to 2.12.6 and then 2.12.7 just to see when it happens.

nothing regarding any of this has changed

I just tried upgrading to 2.12.6 and I get the same error. I'm wondering what my be wrong with my setup.

something JVM/classpath related, can't say more without more information about your overall setup

Sorry for the long output, but this is what I get with -Stree

thats not interesting really

the relevant graal js deps are there. try 2.12.4, I suspect that to be broken too

maybe even delete .cpcache and 2.12.5 might be broken after too

Let me try

@pedrorgirardi I suspect your error message has to do with deps in datalevin, it seems it pulls in GraalVM SVM: https://github.com/juji-io/datalevin/blob/4e699c5a45cc0013420b70afdf5dcb48199c25e1/project.clj#L35

True @borkdude!

I think datalevin should not be doing that, unless you build for graalvm

but perhaps he has reasons to do it, not sure

Yeah, that's a good point. Let me see if I can simply ignore it because I'm embedding Datelevin in my app.

And @thheller, 2.12.4 works fine too.

odd

ah in 2.12.6 I updated the graal-js dependency. so I guess thats the cause then

I think he only needs those deps when he compiles a native image: https://github.com/juji-io/datalevin/blob/ab421c34b9abee61ef574a57fb1c75f9033fbba2/native/src/java/datalevin/ni/Lib.java so I think it's worth pointing that out to him and try to get him to move the dep to a profile

oh you also have a graal-related dependency, hmm, that explains it probably

just the graal-js scriptengine, not graalvm related

jdk15 removed nashorn and graal-js was the replacement

but that is built on graalvm?

@pedrorgirardi you can try manually adding [org.graalvm.js/js "21.1.0"] and [org.graalvm.js/js-scriptengine "21.1.0"]. maybe those fix it too (newer versions than shadow-cljs currently uses)

Hm, I tried tried:

datalevin/datalevin {:mvn/version "0.4.31"
                       :exclusions [org.graalvm.nativeimage/svm]}

no, not built on graalvm (as in the actual JVM)

Will add the dependencies @thheller.

fwiw datalevin uses 21.0.0.2

Yes @borkdude you right, that's what I have in my classpath

org.graalvm.nativeimage/svm 21.0.0.2

@huahaiy Please read this discussion when you are awake :) - there might be a way to exclude the graalvm specific deps in datalevin as a JVM lib

this is one of those situations where I recommend keeping your CLJS setup separate from your CLJ setup. way too annoying to deal with dependency conflicts such as this

Tests are passing with org.graalvm.js/js {:mvn/version "21.1.0"}, will try to upgrade Shadow CLJS now.

@thheller I think this shouldn't have happened in the first place, probably both dependencies should be opt-in

if 21.1.0 fails just downgrade to 20.1.0 which is what 2.12.5 and before used

Ok

maybe move datalevin to a CLJ specific alias that isn't used when running CLJS

That's a good idea!

But this fixed it

org.graalvm.js/js {:mvn/version "20.1.0"}
  org.graalvm.js/js-scriptengine {:mvn/version "20.1.0"}

I think I will try to move server only dependencies to its own alias 😐

Thank you very much @thheller and @borkdude!

daily fun: I am doing something wrong and hot reload results in an infinite loop eating up all my memory

Holding Code references in State I am generating the UI, kinda a must to hold it in the state at some point.

that likely is an invalid reference. holding on to some state does not cause an infinite loop

it is an invalid reference according to some stack trace snippets, but I don't really understand what it says, and I am sure it's me doing the incorrect thing not some bug in the tools I use Uncaught TypeError: Cannot read property 'cljs$core$async$impl$protocols$WritePort$put_BANG_$arity$3' of null

this is just one of the weird errors

that error is a core.async put on nil

hmm

(>! nil something)

yes, thank you, I understand what you mean and it fits very well, I can easily imagine that react runs some piece of code that references to the old queue before the hot reload

> shadow-cljs is rather strict about namespace references dunno, without the linter I wouldn't know half my imports are missing : D

I thought putting defonce on the channel will solve this issue with the null, but no

don't know what you are refering to

put on nil. I thought that because the page is reloading out of order, some react registered thing on the callstack sees the channel I am putting on as nil, because it was removed from under it. So I defined the channel with defonce not def.

but really, the bigger issue is that somehow the interaction between shadow-cljs hot reload and my react code results in a memory leak and kills my browser process

it started when I pust unsub and close into the return functions of my react useEffect hooks, before that I only got the usual memory leak message from react that i am trying to do something with unmounted state, and I thought I am fixing something, but actually managed to make it worse

https://i.imgur.com/vT6qiNq.png

one bug I can see is the (swap! timeouts conj @timeouts ...). remove the @timeouts

🙂

thank you

and I think the use-layout-effect is wrong, looks like it is missing a wrapping (fn [] ...)

also you are always recur'ing, so there is never a check whether it should stop or not

what would such a check look like

(when-some [msg (<! notification-chan] ... (recur))

my understanding was that inside go-loop, <! is blocking, if I close the channel, it should not call recur

clearTimeouts is also using map lazy seq,so it never actually clears anything

that is incorrect. when you take from a channel and that is closed it returns nil

yeah, as you see, I was editing the code before I sent the screenshot

I see, thanks for the correction

This is needed because I am using a GraalVM method to detect if we are running in GraalVM, which would use GraalVM specific binding for LMDB. Is there another reliable way to detect this?

You can detect this using a System property

which one?

`Boolean.getBoolean("com.oracle.graalvm.isaot")`?

I think you can use "org.graalvm.nativeimage.kind" "executable"

or perhaps "org.graalvm.nativeimage.imagecode" "runtime"

I usually use one of both

ok, let me try that, thanks!

@huahaiy You can also make a top-level variable that captures one of your own environment variables during graalvm compilation

and then use that accordingly

I am following a dynamic export (https://shadow-cljs.github.io/docs/UsersGuide.html#_dynamic_exports) to emit code to be used as node libraries and one of my forms is a defmacro. I currently get an error when I compile the code as Can't take the value of macro ...path-to-var what do I need to do here?

I already have (:require-macros [my.core.ns :refer [macro-var]) in top level

I made the code available online https://github.com/wandersoncferreira/respondent/blob/c420359ca838c510d0183be3452c293d137cd9b2/src/respondent/core.cljc#L127 this is the macro I want to export

@iagwanderson: I believe you need a (:require-macros [respondent.core]) in a respondent/core.cljs file, it requires the macros from its own namespace. I haven't done it in a .cljc file, but I guess you can just add it to the top there as well for :cljs.

I tried to add

#?(:cljs (:require-macros [cljs.core.async.macros :refer [go go-loop]]
                            [respondent.core :refer [behavior]]))

I don't think you need the :refer, but I also don't expect that to be the issue. I don't have any specific ideas, but check out https://code.thheller.com/blog/shadow-cljs/2019/10/12/clojurescript-macros.html, if you haven't yet.

@iagwanderson https://code.thheller.com/blog/shadow-cljs/2019/10/12/clojurescript-macros.html missing the self-require as oliver said

I will read the post first.. interesting bit already: > > I strongly recommend writing your macros in 2 separate files until you feel comfortable with that. I still do it for 100% of my macros.

yeah, cljc makes things a lot more complicated

Thanks for help @oliver and @thheller... getting closer to the answer here.. I do not have the error while compiling, but when I run the node.js script using the library it gives me undefined for the macro https://github.com/wandersoncferreira/respondent/blob/main/src/respondent/behavior.cljs

might be Gotcha #3 now 😃 will change it here...

I need my ClojureScript SPA to know of URL that differs from when I develop (run locally) and when the app gets deployed into production. I've been scrolling through the documentation... but nothing stands out to me as useful. I assume this is a quite common need, so I've come to conclusion that I just don't have the right terminology to find it. Can anyone give pointers?

@thheller I might have found the issue. I believe the first implementation was already good. However, if I try to refer to my macro anywhere other than in the first position of a form I get the same error Can't take value of macro.. .. I tried two things 1) calling my macro inside #js {:behavior (behavior)} export map and it worked! and 2) added (println (identity behavior)) to the code and got the same error Can't take value of macro.... maybe I cannot export macros ?

@jacob429: probably the easiest way is to use a Closure define: https://shadow-cljs.github.io/docs/UsersGuide.html#closure-defines, so for instance in a namespace my.config you do: (goog-define some-url "<http://localhost:8091/whatever>") and then in the release build you can set it via :compiler-options {:closure-defines {my.config/some-url "<https://prod-url>"}} or you override this via CLI with --merge-config.

I've also used shadow-env and aero before to put this into EDN files and load at compile time, see: https://github.com/mhuebert/shadow-env#example-usage-with-aero, but just today I replaced all of that with Closure defines, because the dev config always bled into the release build if there was a watch process running.

If anyone else has a better setup for this, then I'd be interested in that as well!

Ah, @iagwanderson, I hadn't looked at the rest of the thing. I don't think exporting a macro makes sense. What would JS do with that? The macro is expanded at CLJS compile time. Hence the error message that you can't take its value.

I did stumble over shadow-env but it seemed overly complicated so I assumed there was a simpler (better?) way.

Yeah, the Closure defines probably are your best bet. But note that they can only be... err... I think booleans, numbers, or strings.

I had some config that needed more structure, like a map and list, so I defined some defines like value-1, value-2, value-3 and in the same config namespace did (def that-data {:key-1 value-1, :key-2 value-2, ...}). There might be a smarter way, but I don't know it.

yeah, makes sense

maybe let a single value point to a file path that gets read/included... then the file path points to an edn file?

hmmm :thinking_face: but it should all happen on build time.

Let's see if anyone else pitches in with ideas 😄
