321ed53e3a Fetch module doesn't set invocation parameter as it invokes nothing, so don't let that be an error. 2012-04-23 21:02:39 -04:00

e69e078569 More robust remote sudo. 
The basic idea is sudo /bin/sh -c 'quoted_command'.  We use Paramiko's low-level API to set a timeout, get a pseudo tty, execute sudo and the (shell quoted) command atomically, wait just until sudo is ready to accept the password before sending it down the pipe, and then return the command's stdout and stderr.

This should be faster, as there are no unneeded sleeps.  There are no permissions issues reading the output.  It will raise socket.timeout if the command takes too long.  However, this is a per-read timeout, not a total execution timeout, so as long as the command is writing output and you are reading it, it will not time out.

Local and non-sudo commands remain unchanged, but should probably adopt a similar approach.

Since this is a significant change, it needs a lot of testing.  Also, someone smarter than I should double-check the quoting and execution, since it is a security issue.

2dc9a563ef Allow modules to return facts. 
If the module result contains "ansible_facts", that will be added to the setup
cache.

5fa3d9b148 Teach playbooks to template locally to eliminate the need for Jinja2 on remote nodes. 
You still need jinja2 if using /usr/bin/ansible vs /usr/bin/ansible-playbook though
this could change later by fetching the ansible file with a 'slurp' module.

127.0.0.1, localhost, or the name of the host as returned by
os.uname()[1], Connection.connect() will opt to use LocalConnection
instead of ParamikoConnection.  LocalConnection implements connect(),
exec_command(), put_file(), and close().

4de7bbb169 Allow conditional imports, see examples/playbook3.yml comments for a full explanation. Extensive 
refactoring of playbooks now warranted, which we'll do before we move on.   This variable assignment
system makes nearly all possible magic possible, for we can use these variables however we like,
even as module names!
