PlayContext.delegate_to is the unexpanded template, Ansible doesn't keep
a copy of it around anywhere convenient. We either need to re-expand it
or take the expanded version that was stored on the Task, which is what
is done here.
* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
For "ansible -m setup" over a 25ms link, avoids 65 roundtrips and
reduces runtime from 5.7s to 4.1s (-28%).
For "ansible -m setup" over a simulated 250 ms link, reduces runtime
from m27.015s to 0m8.254s (-69%).
* Use identical logic to select when stdout/stderr are merged, so
'stdout', 'stdout_lines', 'stderr', 'stderr_lines' contain the same
output before/after the extension.
* When stdout/stderr are merged, synthesize carriage returns just like
the TTY layer.
* Mimic the SSH connection multiplexing message on stderr. Not really
for user code, but so compare_output_test.sh needs fewer fixups.
It looks a lot like multiple calls to _make_tmp_path() will result in
multiple temporary directories on the remote machine, only the last of
which will be cleaned up.
We must be bug-for-bug compatible for now, so ignore the problem in the
meantime.
Turns out Ansible can't be trusted to actually check the result
dictionary everywhere it expects one, so put the real exception text
into -vvv output too.
It's used at least by the copy module, even though the result is still
mostly a no-op. _remote_chmod() doesn't accept octal mode, it accepts
symbolic mode. So implement a symbolic parser in helpers.py.
