The old test used syntax that appeared to be bash-specific and did not
work on platforms where /bin/sh did not point to bash. See issue #2742
where copy to solaris hosts failed with the error:
output: {'stdout': '', 'stderr': '/bin/sh: test: argument expected\n',
'rc': 1}
The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source. The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.
Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.
Use DEFAULT_EXECUTABLE when no executable is passed to
_low_level_command_exec
Works as a standard constant - can be overridden in all the normal ways
and defaults to /bin/sh
Motiviation is for a user that only has /bin/bash in /etc/sudoers
If it is a directory, change the destination path by appending the
basename of the source file, like is done if the destination ends with a
/, and try to get the MD5 of the new path.
Instead of having to remember when to use which one, rename template_ds
to template and move the last bit of code from template to varReplace
(which gets used for all string replacements, in the end).
This means that you can template any data type without worrying about
whether it's a string or not, and the right thing will happen.
Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).
This change includes the following changes:
- exec_command() now returns the return code of the command
- _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
- all users of the above interfaces have been improved to make use of the above changes
- all connection plugins have been modified to return rc and stderr
- fix the newline problem (stdout and stderr would have excess newlines)
In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.
