This is used to implement pipelining. Currently not all connection plugins implement pipelining. :kwarg sudoable: Tell the connection plugin if we're executing a command via a privilege escalation mechanism. This may affect how the connection plugin returns data. Note that not all connections can handle privilege escalation. :returns: a tuple of (return code, stdout, stderr) The return code is an int while stdout and stderr are both byte strings. When a command is executed, it goes through multiple commands to get there. It looks approximately like this:: [LocalShell] ConnectionCommand [UsersLoginShell (*)] ANSIBLE_SHELL_EXECUTABLE [(BecomeCommand ANSIBLE_SHELL_EXECUTABLE)] Command :LocalShell: Is optional. It is run locally to invoke the ``Connection Command``. In most instances, the ``ConnectionCommand`` can be invoked directly instead. The ssh connection plugin which can have values that need expanding locally specified via ssh_args is the sole known exception to this. Shell metacharacters in the command itself should be processed on the remote machine, not on the local machine so no shell is needed on the local machine. (Example, ``/bin/sh``) :ConnectionCommand: This is the command that connects us to the remote machine to run the rest of the command. ``ansible_user``, ``ansible_ssh_host`` and so forth are fed to this piece of the command to connect to the correct host (Examples ``ssh``, ``chroot``) :UsersLoginShell: This shell may or may not be created depending on the ConnectionCommand used by the connection plugin. This is the shell that the ``ansible_user`` has configured as their login shell. In traditional UNIX parlance, this is the last field of a user's ``/etc/passwd`` entry We do not specifically try to run the ``UsersLoginShell`` when we connect. Instead it is implicit in the actions that the ``ConnectionCommand`` takes when it connects to a remote machine. ``ansible_shell_type`` may be set to inform ansible of differences in how the ``UsersLoginShell`` handles things like quoting if a shell has different semantics than the Bourne shell. :ANSIBLE_SHELL_EXECUTABLE: This is the shell set via the inventory var ``ansible_shell_executable`` or via ``constants.DEFAULT_EXECUTABLE`` if the inventory var is not set. We explicitly invoke this shell so that we have predictable quoting rules at this point. ``ANSIBLE_SHELL_EXECUTABLE`` is only settable by the user because some sudo setups may only allow invoking a specific shell. (For instance, ``/bin/bash`` may be allowed but ``/bin/sh``, our default, may not). We invoke this twice, once after the ``ConnectionCommand`` and once after the ``BecomeCommand``. After the ConnectionCommand, this is run by the ``UsersLoginShell``. After the ``BecomeCommand`` we specify that the ``ANSIBLE_SHELL_EXECUTABLE`` is being invoked directly. :BecomeComand ANSIBLE_SHELL_EXECUTABLE: Is the command that performs privilege escalation. Setting this up is performed by the action plugin prior to running ``exec_command``. So we just get passed :param:`cmd` which has the BecomeCommand already added. (Examples: sudo, su) If we have a BecomeCommand then we will invoke a ANSIBLE_SHELL_EXECUTABLE shell inside of it so that we have a consistent view of quoting. :Command: Is the command we're actually trying to run remotely.
