[leo_commons][nfs] The disk free space can be wrong

[mocchira]

As leo_file:file_get_mount_path/1 ( https://github.com/leo-project/leo_commons/blob/1.1.7/src/leo_file.erl#L110 ) doesn't follow every symlink included in a given path.
A path given to that function should be canonicalized as readlink -f does.

memo

According to the report https://groups.google.com/d/msg/leoproject_leofs/4MFbLH9IVj4/MaqXsJHRAgAJ ,
There seems to be another issue. ( still not reproduced )

how to implement

don't

os:cmd("readlink -f " ++ FilePath). %% doesn't work on possibly BSD based systems like OSX

instead

do port http://stackoverflow.com/questions/1055671/how-can-i-get-the-behavior-of-gnus-readlink-f-on-a-mac into erlang with file:read_link_info, filename:basename and filename:dirname.

impl ( confirmed on osx/linux )

todo

• add unit tests
• call leo_file:file_get_canonicalized_path in leo_file:file_get_mount_path
