      Description

      While implementing https://tracker.mender.io/browse/CFE-2458 I found some issues with files_single_copy.

      My testing indicates that a setting for files_single_copy in body agent control that should not match the promised file does. Effectively this is equivalent to having files_single_copy set to .*.

      I found no existing mention of files_single_copy in the core acceptance tests so I wrote some. The tests in core pr 2658 test that files_single_copy works as expected in the case of an exact match (subsequent copies are skipped), files_single_copy does not apply to non matching expressions, and that files_single_copy applies when a regular expression is matched.

      Failing test summary:

      • agent_control_files_single_copy_does_not_apply_to_nonmatching_files_1.cf
      • agent_control_files_single_copy_does_not_apply_to_nonmatching_files_2.cf
      • agent_control_files_single_copy_does_not_apply_to_nonmatching_files_3.cf
      • agent_control_files_single_copy_does_not_apply_to_nonmatching_files_4.cf
      • agent_control_files_single_copy_does_not_apply_to_nonmatching_files.cf
