When running ansible -C, I get a traceback that ends with
AttributeError: Values instance has no attribute 'diff'
This fixes on_file_diff to behave similar to
PlaybookRunnerCallbacks.on_file_diff().
I guess my previous pull request was confusing, by changing the message to something we already do for tasks, it makes it more clear.
Just like we say:
TASK: [foo bar]
skipping: [system01]
The message now is more clear:
PLAY [wagawaga] *******************************
skipping: no hosts matched
It makes it clear that we are skipping the play, just as is done for a task when a condition is not met.
Currently the message prepared for --oneline mode adds a newline to the msg-string, which is then printed (adding another newline). This change removes the added newline so that successes and failures do not differ in output (except if the output is multiline).
Several modules (e.g., pip) return stdout and stderr together in a "msg" variable (and the module development docs seem to suggest that the standard practice is to return status in this variable).
This change ensures that it is printed out with correct formatting (most importantly, with newlines appearing as newlines instead of \n).
Since a skipped/ignored action is _very_ different from actual changes to a system, it always bothered me that it was not easily distinguishable when skimming the output. This change makes ignore/skip a different color, and I chose cyan. Contemplated using dark-gray/blue, but prefered something that is readable with most terminal colors.
This change makes a distinction between no_hosts_matched and no_hosts_remaining.
In both cases we do not start facts-gathering, or run any tasks.
In the case that there are no more hosts remaining, we abort running tasks and abort the playbook.
I also cleaned up the leftovers from the previous patchsets, as these are no longer required.
This closes#1187.
Example playbook:
```yaml
---
- hosts: emptygroup
tasks:
- action: command date
- action: command false
- hosts: all
gather_facts: False
tasks:
- action: command ls
- action: command false
- action: command true
- hosts: all
tasks:
- action: command true
- action: command false
- hosts: all
tasks:
- action: command pwd
```
The 'hostname' variable is then unicode, which breaks interpolating
stdout etc. contents into the output strings (they are bytes and cannot
be converted to Unicode using ASCII codec)
