Assuming that I cannot run something like this with Fabric:
run("svn update --password 'password' .")
how’s the proper way to pass to Fabric the password for the remote interactive command line?
The problem is that the repo is checked out as svn+ssh and I don’t have a http/https/svn option
Try SSHkey. It allows you to connect to the server without password.
In this case, you will have to setup a sshkey between your remote server and the repo.
At remote server: Generate key pair
Leave the passphase empty!
This will generate 2 files
Then, append the content in id_dsa.pub to ~/.ssh/authorized_keys at repo server.
Your remote server will be able to update the source tree without any password required.
