emacs-app @30.1_1+nativecomp+rsvg+treesitter launches multiple bash processes that do not terminate

[william-r-greene (William R. (Bill) Greene)]

Shell or process commands interspersed with setenv calls results in Emacs starting hundreds of bash processes (I stopped counting at 532.) that do not terminate.

I couldn't reproduce this.

Any chance your bashrc is launching background processes? If so, they'll inherit the shell's stdout fd, and emacs will block waiting for that to finish before considering the shell command done.

It looks like that was indeed happening. Here is the fragment from my .bashrc:

  # Try to determine what shell is running:
  if   [ -n "$($SHELL -c 'echo $ZSH_VERSION')" ]; then
      export WHICH_SHELL="${SHELL} version ${ZSH_VERSION}";
  elif [ -n "$($SHELL -c 'echo $BASH_VERSION')" ]; then
      export WHICH_SHELL="${SHELL} version ${BASH_VERSION}";
  else
      export WHICH_SHELL=not_zsh_or_bash;
  fi;

Thanks.
