Re: [Fab-user] Rsync_project in 1.5.1

Hi Chris,

Thanks for your reply! The wrong format of env.host_string is the root cause of my failure. After correcting it per your suggestion, everything is working like charm!  Here is the error I got before.

Cheers,

carl

Greetings,

please note you forgot to provide a (sanitized) log of an actual
fabric run containing the verbatim error message and possible
traceback, so it is very hard for us to debug your problem.

However, from the way you add "userXXX@" to env.host_string in your
os.system call, I assume your host_string is just missing the user
portion[0][1][2]. Unless it is identical to your local username, this
will be a problem since local_username is the default value for the
remote username[3][4].


[0]: The docs (http://docs.fabfile.org/en/1.4.3/usage/env.html#host-string)
could be a bit clearer on that, and are lacking examples. I haven't
verified it recently, but the way I understand and use it in my code,
basically,
    [code]env.host_string = env.user + '@' + env.host[/code].
