Caching absolute directory
Describe the bug
It's possible that I am just making a stupid mistake, but here is a description of the problem. Trying to cache a directory that is outside the main source folder using an absolute path.
The workspace is "/drone/src".
Configure the drone-cache mount to be "/drone/cache".
Near the end of the build process, run "ls -al /drone" to observe the directory contents.
ls -al /drone
total 16
drwxr-xr-x 4 root root 4096 Mar 14 16:26 .
drwxr-xr-x 1 root root 4096 Mar 14 16:25 ..
drwxr-xr-x 12 root root 4096 Mar 14 16:27 cache
drwxr-xr-x 17 root root 4096 Mar 14 16:26 src
So, everything seems to be in place. The final step in the drone pipeline is to run rebuild:
"name": "rebuild-cache",
"image": "meltwater/drone-cache",
"mount": mountpoints
...
mountpoints is a variable that in this case should be ["/drone/cache"]).
Archive format isn't specified, so it's using the default (tar).
The final output of the rebuild shows an error that the directory doesn't exist.
level=error name=drone-cache ts=2023-03-14T16:27:20.348382792Z caller=main.go:628 err="[IMPORTANT] build cache, source </drone/cache>, make sure file or directory exists and readable, lstat /drone/cache: no such file or directory\n"
Expected behavior /drone/cache can be cached and restored correctly.
Should it be working? and are there currently test cases in CI which test the absolute path feature?
