On Python 2, shlex.split() raises if you pass it a unicode object with
non-ASCII characters in it. The Ansible codebase copes by explicitly
converting the string using to_bytes() before passing it to
shlex.split().
On Python 3, shlex.split() raises ('bytes' object has no attribute 'read')
if you pass a bytes object. Oops.
This commit introduces a new wrapper function, shlex_split, that
transparently performs the to_bytes/to_unicode conversions only on
Python 2.
Currently I've only converted one call site (the one that was causing a
unit test to fail on Python 3). If this approach is deemed suitable,
I'll convert them all.
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
You cannot call bytes(obj) to get a simple representation of obj on
Python 3! E.g. bytes(42) returns a byte string with 42 NUL characters
instead of b'42'.
Since we explicitly set convert_bare=False in the template lookup
code, but still want individual looks that call listify directly to
convert bare variables if needed.
Fixes bugs related to creating Templar() objects on the fly, where
the shared loader objects (serialized to TaskExecutor) aren't used
so information loaded into plugin loaders after forking is lost.
Fixes#11815
This is unsafe and we debated re-adding it to the v2/2.0 codebase,
however it is a common-enough feature that we will simply mark it
as deprecated for now and remove it at some point in the future.
Fixes#11718
added deprecation warning
fixed display.deprecated to make version optional (code already assumed this)
turned warning + 'deprecated' in plugin loader into actual call to deprecated()
This allows not messing up the wonderful error reporting that is
carefully created. Instead of:
$ ansible-playbook foo.yml
[ERROR]: ERROR! 'foo' is not a valid attribute for a Task The error appears
to have been in '/Users/marca/dev/git-repos/ansible/foo.yml': line 4, column 7,
but may be elsewhere in the file depending on the exact syntax problem. The
offending line appears to be: tasks: - name: do something ^ here
we get:
$ ansible-playbook foo.yml
ERROR! 'foo' is not a valid attribute for a Task
The error appears to have been in '/Users/marca/dev/git-repos/ansible/foo.yml': line 4, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
tasks:
- name: do something
^ here
which is much nicer.
