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!

apart from the stack size issue i think

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
