[![Hex version](https://img.shields.io/hexpm/v/safeio.svg "Hex version")](https://hex.pm/packages/safeio)
An OTP library for checking that specific directories are safe to use.
This project is the result of problems with handling broken NFS mounts.
Our application would regularily use `filelib:is_regular/1` with a path that
is in an NFS mounted directory.
The problem is, whenever such a mount point gets _stuck_, e.g. because of an
NFS-server outage or a network problem, **all** file operations, i.e. calls to `file` and
`filelib` modules, block from the moment the first path in a _stuck_ directory is accessed.
Even operations on paths outside the broken mount point are blocked.
This library aims to provide a workaround for this problem by providing operations
that check if a path is accessable using an external process instead of `filelib` or `file`.
$ rebar3 compile
To check if a file is a regular file, use `safeio:is_regular/2`:
