I will ask in here too, has someone ever faced Clojure (runtime) exceptions disappearing when inside a Runnable? Disclaimer I have the uncaughtExceotionHndler in place already..

@richiardiandrea: that's the reason for the auto-flush print stream thing in boot

i don't think anything is getting lost

it's just that buffers aren't being flushed

so when you try to print the stack trace you can't

this mostly happens when the jvm exits while there are threads that are still wanting to write stack traces to stdout

the jvm can exit before the printing is done

Oh

My jvm is up and running and I see from that moment on that the print (clojure.logging) is not actually outputed

So you are saying that I need to flush log4j or something?

hm

i don't know about log4j

the jvm isn't exiting?

Kk I will try to follow that route

Nope

The error is a simple Cannot find seq ...runtime compile error

I'll need a repro case, it is better ;)

what does this error main?

looks like a bug in 2.6.0, I use 2.5.5 and I see the warnings

@jiyinyiyong: do you have a stack trace?

i don't recognize start-stack-editor!

https://github.com/Cirru/boot-stack-server/blob/master/compiled/src/stack_server/core.clj#L21 the task is mine.

That's all the stack trace I current see. is there any options to display more stack traces?

@jiyinyiyong: boot -vvv (# of vs controls the level)

@micha still got only this logs even with -vvv

Hmm, anyone else had problems with boot install in a Docker container? Getting the following:

Retrieving tools.namespace-0.2.11.jar from 
             clojure.lang.ExceptionInfo: java.lang.Exception: can't find jar file

                                ...                    

The Dockerfile does this:

RUN (mkdir brn \
&& curl -sL  | tar xz -C brn \
&& cd brn \
&& boot install)

@vikeri: that's a really weird one. looks like the filesystem isn't synced or something? i've seen errors similar to thta (clearly related to bad data inside, on docker FS) when i was doing volume sharing on OS X ~2 yrs ago

maybe try downloading and boot install as 2 separate RUN commands?

hmm, altho it occurs to me all the files in your case are inside docker, so volume sharing shouldn't be the culprit

@vikeri: there are docker images floating around github for boot

https://github.com/adzerk-oss/boot-clj-docker-image

@flyboarder: I tried it too. Still not really working

are you mounting the filesystem from host?

there are issue with docker filesystem sync, i dont think it should cause issues when running commands like that within the container but if a path overlaps with something mounted then who knows...

@vikeri: if you are just running boot install does boot know about the location where the tar is being extracted? it installs the jar from it’s fileset of out-put files if im not mistaken (things moved to target folder)

I think what you want is to download and extract that file from a boot task then install it, otherwise boot doesn’t know about the extracted files.

cljsjs projects have examples of downloading and extracting things

I run boot install in the right directory, I think it might be a memory issue with docker possibly. Continue investigating tomorrow

What is the easiest way to get your app's version in code after compiling an uberjar? Providing the version to the manifest?

@kenny: are you trying to load it on the server? or client side of your app? I think the best way would be to generate a ns during build that you can reference from your app

hmmm actually that might be a good thing to build into boot-semver :thumbsup:

i use a macro for that

in cljs

when you call the macro in your cljs code it does git describe in the shell and returns the result, which then gets compiled into the cljs namespace

Nice the above ^ I am sending the version.properties along uberjar or js files.

yep, for applications i like just using the git tag

because there is no pom or anything

using git tag makes it easy to link to things in github too, which is what we have in our application

if you're an admin there is a little thingy on the side you can hover over to get a link to the github commit

so QA testers can check to see what's been merged into the application they're testing

things like that
