Copy link

The actions/cache/save@v4 action fails to create cache archive if there are "dead" circular symbolic links inside. The following error shows up in the output:

Warning: ELOOP: too many symbolic links encountered, stat '/home/runner/work/amneziawg-openwrt/amneziawg-openwrt/openwrt/staging_dir/toolchain-mips_24kc_gcc-11.2.0_musl/initial/lib/lib'
Warning: Cache save failed.

Problematic links:

$ find . -follow -printf ""
find: ‘./staging_dir/toolchain-mips_24kc_gcc-11.2.0_musl/mips-openwrt-linux-musl/lib/lib’: Too many levels of symbolic links
find: ‘./staging_dir/toolchain-mips_24kc_gcc-11.2.0_musl/initial/lib64/lib’: Too many levels of symbolic links

find: ‘./staging_dir/toolchain-mips_24kc_gcc-11.2.0_musl/lib/lib’: Too many levels of symbolic links

All these are circular symlinks, e.g.:

lrwxrwxrwx 1 runner docker    3 Sep  7 19:56 lib -> lib
lrwxrwxrwx 1 runner docker 3 Sep  7 19:56 staging_dir/toolchain-mips_24kc_gcc-11.2.0_musl/initial/lib/lib -> lib
