The copy action plugin creates its own tmp dir for each file that it
copies to the target machine. However, it does not clean up the
original tmp path it was given when run() is called. This cleans up the
tmp path before it begins looping on source files.
For this, add internal "original_basename" param to file module,
similar to copy module. (Param name is a bit misnormer now, should
be treated as "original basepath").
If src param to copy is a directory, all files under it are collected
and pushed one by one to target. Source dir path handled in a way
simalar to rsync: if it ends with slash, only inside contents of
directory are copied to destination, otherwise the dir itself is
copied (with all contents of course). Original idea and implementation
by https://github.com/ansible/ansible/pull/1809 . Rewritten to address
review comments and simplify/correct logic.
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 setting force=no caused copy to subversively
fail when target did not exist on remote host.
Caused by Runner._remote_md5 returning 1
when files don't exist, rather than 0.
The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source. The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.
Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.
If it is a directory, change the destination path by appending the
basename of the source file, like is done if the destination ends with a
/, and try to get the MD5 of the new path.
