This was causing wrong behaviour when `prev_state` was `hard`-link,
since the `file` module tried to apply the same `state` on the new
file, causing unexpected errors.
Particularly, both `overlay` and `devicemapper` storage drivers in
docker use hardlinks to share files between layers. This causes
most ansible playbooks to fail when working with files from layers
below.
* Fail if an empty string is set as src for copy module
Fixes#27363
* Cleanup task formatting on copy tests
Use multi-line YAML
Add debug statements with verbosity: 1 rather than leave them in there commented out.
* Add test for empty string as source
* Do more checks in order to add more specific errors messages
Add more integration tests for the various failure scenarios.
Cleanup some syntax on existing integration test tasks.
* set output_dir_expanded using module result
'path' values are expanded using 'expandvars' too
* foo.txt is located in 'files' directory
* Use 'role_path' and 'connection: local' for local paths
'{{ role_path }}/tmp' is used for generated paths
* Use local connection with local paths
/tmp/ansible-test-abs-link and /tmp/ansible-test-abs-link-dir are
defined by targets/copy/files/subdir/subdir1/ansible-test-abs-link
and targets/copy/files/subdir/subdir1/ansible-test-abs-link-dir links.
* task names: add a suffix when same name is reused
* Check that item exists before checking file mode
then error message is more explicit when item doesn't exist
* Use output_dir_expanded only when necessary
* Enforce remote_user when root is required
* Fix remote path
* Use different local & remote user
this is useful when controller and managed hosts are identical
* Checks must not expect output of tested module to be right
* Use a temporary directory on the controller
* Use sha1 & md5 filters instead of hardcoded values
* Use 'remote_dir' for directory on managed host
* Workaround tempfile error on OS X
Error was:
temp_path = tempfile.mkdtemp(prefix='ansible_')
AttributeError: 'module' object has no attribute 'mkdtemp'"
