Clojurians Log v2

See latest issue in the borkdude/jet repo, that might give you an idea 😅

@borkdude and I had a lot of fun over this 😞

@ericdallo in a gist, when you use StaticExecutableWithDynamicLibC its compiling the binary with syscalls stubbed out to glibc which it may or may not use. So when you run in a non glibc OS like alpine and the binary wants to make such a call, it will segfault and there no saying when it may happen. Hence we use the musl lib which is a full c stdlib impl designed to be static linked unlike glibc

the segfault manifests as a cryptic file not found

also when it cannot find the .so file

@rahul080327 could you take a peek at that latest jet issue?

having a look

@borkdude I took a look and it seems to be the same issue on clojure-lsp right? jet didn't have the static binary compiled with musl too, right?

exactly

I see, so it just confirm that using musl is always the safest option right? I always thought that but on some conversation recent on some thread, I (miss?)understood that there are cases where musl doesn't work but glibc works, is that right?

I haven't encountered a situation where a musl compiled binary doesn't work and glibc did work better

Good, so that's sounds safe enough to me

thank you!

There is one caveat with musl concerning the stack size

my workaround for that is this: https://github.com/borkdude/jet/blob/12dc569e2b48a97db016719d93e424c645ac3453/src/jet/main.clj#L149-L171

and:

BABASHKA_STATIC=${BABASHKA_STATIC:-}
BABASHKA_MUSL=${BABASHKA_MUSL:-}

if [ "$BABASHKA_STATIC" = "true" ]; then
    args+=("--static")
    if [ "$BABASHKA_MUSL" = "true" ]; then
        args+=("--libc=musl"
               # see 
               "-H:CCompilerOption=-Wl,-z,stack-size=2097152")
    else
        # see 
        args+=("-H:+StaticExecutableWithDynamicLibC")
    fi
fi

So what I do is set the stack size to 2mb and run the main program within a thread

good to know about this workaround, will use it too
