From 74f07ecc35106d2ea7032816045fe6c8388ec0f3 Mon Sep 17 00:00:00 2001
From: "LocalAI [bot]" <139863280+localai-bot@users.noreply.github.com>

Subject: [PATCH] fix(backends): quote $CURDIR in run.sh (fixes backends in
 paths with spaces) (#10519)

fix(backends): quote $CURDIR in run.sh so backends work in paths with spaces

The backend launcher scripts derive their own directory with
CURDIR=$(dirname "$(realpath $0)") and then referenced it unquoted as
$CURDIR (e.g. [ -f $CURDIR/lib/ld.so ], export LD_LIBRARY_PATH=$CURDIR/lib:...,
exec $CURDIR/<binary> "$@"). When a backend is installed under a path that
contains a space - notably macOS's ~/Library/Application Support/... - bash
word-splits the unquoted $CURDIR, so the test builtin fails with
"binary operator expected" and exec tries to run ".../Library/Application",
yielding "No such file or directory". The backend never starts, surfacing as
a gRPC "service not ready" error and an HTTP 500. Quote $CURDIR (and the
realpath "$0") in every affected run.sh; no logic changes.
