Yep - 10.13.2

Although I also got these same kinds of errors on CircleCI w/o Mac OS

can you test running the npx shadow-cljs server standalone and if killing it with CTRL+C leaves the orphan java process?

no orphan process there

right now in one project, i can start a server with just a warning (“TCP Port 9630 in use” - despite no java process still running), while in another project (maria) when I try to start a server, I get this:

mattpro:editor MattPro$ npx shadow-cljs server

thats the nrepl server failing

if you set a fixed port for nrepl that happens

ah i’ll remove that option

yeah fixed ports are a problem when running multiple shadow-cljs instances

in this case there was no other instance visibly running

hmm I don't understand. if port 9630 is blocked something must be running

but.. when I run this in the maria project I don’t see any main processes so maybe i’m just not seeing them

ps ax | grep java

doesn't list anything?

looks like they are called java processes when i run the command from maria

and main when i run from my other project

hmm? should always be called java

no idea what main would be?

it starts out as java, and then at some point changes to main (or the first process ends and another one called main starts, however that works)

hmm what does ps ax for that process look like?

same pid

PID   TT  STAT      TIME COMMAND
77080   ??  Ss     1:20.61 /usr/bin/java -Djava.util.logging.config.file=target

where is it called main?

in Activity Monitor

when you run npx shadow-cljs server that is called main as well?

same — while it’s loading it is called java, around the time it’s finished loading the name changes to main

so weird

my mac is still on 10.12 where this doesn't happen

currently switching my main machine over to windows

might attempt the macos upgrade later

this still never works:

mattpro:editor MattPro$ npx shadow-cljs start; npx shadow-cljs clj-run '(+ 1 1);'
shadow-cljs - config: /Users/MattPro/Documents/sites2017/maria/editor/shadow-cljs.edn version: 2.0.144

shadow-cljs - socket connect failed, server process dead?

I don't get it, that always works for me

whats the state of java processes directly after that?

can you rm -rf target/shadow-cljs before running that

and then run the command?

ls -ahl target/shadow-cljs after?

npx shadow-cljs start; npx shadow-cljs clj-eval '(+ 1 1)'

i have ssh’d into circleci right now, so whatever OS they are running, and same thing:

anything in server.stderr.log or server.stdout.log?

so the server is running

and running npx shadow-cljs clj-eval '(+ 1 2)' probably works now

ah it doesn't work since you still have the older version that kills the port file

root@b4b33f696572:~/project/editor# npx shadow-cljs stop
shadow-cljs - config: /root/project/editor/shadow-cljs.edn version: 2.0.140

i can upgrade there, one sec. on my mac i am using the latest v

yeah the older version still kills the port file, so none of the later commands works

shadow-cljs - socket connect failed, server process dead?
deleted pid file, please retry command to start new server

newer version doesn't delete the file anymore

https://github.com/thheller/shadow-cljs/blob/master/.circleci/config.yml

see the start and then wait-for-server.sh which could probably just be sleep 1

but that setup seems to work on circleci

no idea about the mac stuff

after updating, server starting seems to go on forever. i also tried rm -rf target

root@b4b33f696572:~/project/editor# npx shadow-cljs start
shadow-cljs - config: /root/project/editor/shadow-cljs.edn version: 2.0.144
shadow-cljs - updating dependencies
shadow-cljs - dependencies updated
shadow-cljs - server starting .........................................................................................................................................................................................................................................................................................................................................

it starts way slower due to no AOT

what does the .log files say?

i think it is stuck

one sec

this is circleci now right? kinda confusing thinking about both setups

the log files should at least say something

oh, i see. the version deployed to maria on GH still has nrepl-port specified so in stderr we have:

i thought putting a sleep command in between start & the command would be a fix for all of this, but my colleague (on mac os) still got that same error even with shadow-cljs start && sleep 2 && shadow-cljs clj-run ...

(all of the stuff i am pasting now is circleci)

can we please stick to debugging one thing at a time

I doubt that the mac and circleci issues are related

circleci I fixed by sleeping yes

does that not work for you?

if && don't work can you try multiple commands like in my circle config?

on circleci i stopped using server or start entirely

the reason i ssh’d into circleci was because it seemed like the same error

on mac can you please delete target/shadow-cljs entirely, kill all java processes

then run npx shadow-cljs start alone

then run npx shadow-cljs clj-eval :foo

not combined, after each other manually

yes, that worked

as does npx shadow-cljs stop?

I mean the java process is properly killed?

yes

same deal, delete target/shadow-cljs, kill all java

npx shadow-cljs start && npx shadow-cljs clj-eval :foo

that causes the error immediately?

yep

mattpro:editor MattPro$ npx shadow-cljs start && npx shadow-cljs clj-eval :foo
shadow-cljs - config: /Users/MattPro/Documents/sites2017/maria/editor/shadow-cljs.edn version: 2.0.144

shadow-cljs - socket connect failed, server process dead?

now npx shadow-cljs clj-eval :foo alone works?

however now i am able to npx shadow-cljs stop.

ie. the server is running

one sec

now that works yes

I have no clue what is happening. the node process that starts the server waits until the port file appears

the server writes the port file AFTER startup completed

is writing the port file the very last thing it does?

does it work if you reset everything and add the sleep?

what I don't get is why it works on my machine. macOS version shouldn't make a difference

adding a sleep 1 works for me now, but that is the same command that didn’t work for my colleague

I'll just shuffle things arround a bit so that the node process waits a bit until after the file appears

and maybe does a test run itself

I have absolutely no other ideas

what kind of hardware are you using? your colleague?

maybe its just a timing issue?

i’m not sure what his is. mine is a late 2013 macbook pro

hmm I have the mid-2015 one, shouldn't be that much of a difference though

i am not clear on the difference between what i get locally and the stuff i am replicating on circleci

https://circleci.com/gh/mhuebert/shadow-circleci/2

^^ there i am running shadow-cljs start and clj-eval as two separate commands (no sleep) and getting an error

yes I have that happening in my circleci setup as well

you could fork that repo & add to circleci to ssh in if you wanted to try other stuff (https://github.com/mhuebert/shadow-circleci) it is just a plain docker image with java+node+git

thats why I added the wait-for-server.sh

but thats just basically a sleep 1

right. is what’s happening there different in some way from what happens on my machine?

I have no idea

there shouldn't be

so it appears to work now on circleci

will push a new version once I figure out how to configure npm on windows

https://circleci.com/gh/thheller/shadow-cljs/104

looks good now though, no sleep

[email protected] should hopefully fix this

:thumbsup::skin-tone-2:

my test works too: https://circleci.com/gh/mhuebert/shadow-circleci/3

phew
