[Bug]: Error running devbox shell in environment with exported Bash function

[apgrucza]

Current Behavior (bug) To reproduce, run these commands:

foo() { echo foo; }
export -f foo
devbox shell

This error appears:

bash: export: `BASH_FUNC_foo%%=() {  echo foo}': not a valid identifier

Despite the error, the foo function is still available in the shell.

Expected Behavior (fix) The error should not appear.

Additional context My devbox version -v:

same here any work around?

Apparently, since the exported functions are available inside the devbox environment, the workaround is just to ignore the error.

I'ld still love it for the error not to appear, though, as I wasted quite a bit of time trying to figure out what was wrong with my env.

@albx79 , same thing, I spent about a few hours trying to figure out what went wrong

$ devbox shell
✓ Computed the Devbox environment.
Starting a devbox shell...
/tmp/devbox504213459/.zshrc:export:12: not valid in this context: BASH_FUNC_ml%

For some reason devbox take working function from my env

ml()
{
  eval "$($LMOD_DIR/ml_cmd "$@")"
}

and create this

export BASH_FUNC_ml%%="() {  eval \"\$(\$LMOD_DIR/ml_cmd \"\$@\")\"\
}";

Debug info

$ cat  /tmp/devbox504213459/.zshrc | grep BASH_FUNC_ml%% -B 1 -A 1
export BASH_ENV="/usr/share/lmod/lmod/init/bash";
export BASH_FUNC_ml%%="() {  eval \"\$(\$LMOD_DIR/ml_cmd \"\$@\")\"\
}";

$ zsh --version
zsh 5.9 (x86_64-redhat-linux-gnu)

$ cat /etc/os-release

$ devbox version

Look like it broke init_hook, it not running anymore

[Akiyamka]

plugins (corepack in my case) fails to execute they hooks too

As I understand this code has this form intentionally, but I still can't figure out how to fix the error https://antonyt.com/blog/2020-03-27/exploiting-cgi-scripts-with-shellshock

When i run devbox shell, I get this,

bash: export: `BASH_FUNC_which%%=() {  ( alias; eval ${which_declare} ) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot $@}': not a valid identifier

It doesn't seem to impact anything -- as other folks above have said, or is it really harmless? -- but it makes it hard for me to convince my team we should use this together.

Is there a flag or variable I can set in the dotenv.json file to bypass parsing or evaluating .bashrc or .bash_profile functions? Or is that misguided... that's part of devbox's charm I suppose when it all works smoothly?
