Better to update symlink atime when restoring cache

[tomchang-tubi]

Hey corca-ai,

This tool works pretty well when CI runs with large node modules.
But we noticed a possible improvement on automatically clean — in some cases the cache folder atime doesn’t get updated. so the cache will be deleted in 7 days, even we have testing access the modules.
So one quick fix could be to simply touch the symlink when restoring the cache, so the atime gets refreshed.

bellow is how I test it:

create 1 folder and 1 softlink

lrwxr-xr-x   1 lchang  staff    8 Aug 13 22:29 sl_testlink -> testlink
drwxr-xr-x   3 lchang  staff   96 Aug 13 22:39 testlink

and here is the atime:

.//testlink | atime: 2025-08-13 22:39:39 | mtime: 2025-08-13 22:39:39 | ctime: 2025-08-13 22:39:39

read or modify the files inside this folder doesn't update the atime:

$ echo 123 > testlink/test.txt

.//testlink | atime: 2025-08-13 22:39:39 | mtime: 2025-08-13 22:39:39 | ctime: 2025-08-13 22:39:39

if touch the path the atime will be updated immediately

$ touch sl_testlink

.//testlink | atime: 2025-08-13 22:44:59 | mtime: 2025-08-13 22:44:59 | ctime: 2025-08-13 22:44:59

So how about add a simply touch on the symlink when restoring the cache?
