Thin facade atop fabric

A façade atop fabric2

Overview

I have revisited Fabric (September 2018) to find it can handle multiple threads and multiple connections! This is great news: it makes all my automation faster!

Like with most APIs, I made a façade because Fabric is not congruent to my own programming conventions. This is not bad, just different: The domain I work in is slightly different than what the Fabric developers expect.

Here are the differences:

• All stdout and strerr from the remote machine is annotated, and shunted, to the local logging module.
• A few convenience methods are added:
  • conn.exists(path) - to test if a remote file exists
  • with conn.warn_only(): - context manager if you do not care if your commands fail
  • get(remote, local, use_sudo=False) - allows you to use tilde (~) on Windows to refer to home directory
  • put(local, remote, use_sudo=False) - similar to get, except copies files to remote
  • sudo(command) works with the cd() context manager
  • Result.__contains__() so checking for patterns in command output is simpler:

        result = conn.run("ls /data1", warn=True)
        not_found = "No` such file or directory" in result
