Non-standard modules must read in the arguments file in order to access their arguments, however, when this file is transfered to the remote host it may only have the permissions 600. This means that using sudo and sudo_user will result in permission denied errors when attempting to read the arguments file.
This patch fixes#4438 by explicitly forcing the arguments file to be world readable before executing the module.
This patch also checks specifically for a return code of 255, which
indicates an unknown SSH error of some kind. When that happens, ansible
will now recommend running with -vvvv (if not enabled) or show the
output from 'ssh -vvv' (when it is enabled)
Adds original_transport attribute to Runner to track what the original
transport was before it is changed to 'accelerate'.
If using paramiko in original_transport, uses ParamikoConnection. If
not, falls back to SSHConnection like before.
The 'always_run' task clause allows one to execute a task even in
check mode.
While here implement Runner.noop_on_check() to check if a runner
really should execute its task, with respect to check mode option
and 'always_run' clause.
Also add the optional 'jinja2' argument to check_conditional() :
it allows to give this function a jinja2 expression without exposing
the 'jinja2_compare' implementation mechanism.
Previously, hostvars would only expose a keys() list of hosts that had
been seen yet- however you could explicitly access the host if you knew
the name, and get the content that way. This precludes template code
from being able to safely access information about other hosts if any
limiters/tags were in use.
Additionally, the object was inconsistent for hostvars['myhost'] access
and [x[1] for x in hostvars.items() if x[0] == 'myhost'] access; this is
due to the original derivation from the dict object. .items() would be
handled by dict.items(), using the passed in setup_cache values without
using the actual lookup content.
This patch rebases the class implementation to a py2.6 dictmixin, fixing
those issues and restoring behaviour to match what the docs claim.
Added support of an optional init method for action modules like rsync that need to alter the connection and other inject data before it's established.
