For compatibility with older releases as well as avoiding things like
action: raw executable= show status
to communicate with devices that don't have sh.
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.
This ensures we don't litter remote systems with temporary directories
that don't get cleaned up, as well as speeds things up from not having
to touch every node.
Add constant DEFAULT_MODULE_LANG that defaults to C. Can be set via
environment variable ANSIBLE_MODULE_LANG or configuration variable
module_lang. Updated test-module to have same behavior.
This change avoids the "tcgetattr: Invalid argument" error by making sure the ssh we start does have a proper pseudo-tty.
We could also check whether our current terminal is a proper terminal (by doing a tcgetattr ourselves) but I don't think this adds anything.
This closes#1662 (if all use-cases have been tested: sudo, passwd)
As reported on the mailinglist, the user received a ValueError when the port number was not templated (fixed in #1649) and therefore it was not an integer. This change will catch the exception and provide a proper error so it is more clear.
Update constants.py so that one can specify environmental variable
ANSIBLE_SYSLOG_FACILITY or syslog_facility in ansible.cfg to define
the syslog facility to use. Alternatively, you can specify
ansible_syslog_facility in inventory. Runner now replaces
the syslog facility in the openlog() call with the default or
the injected variables ansible_syslog_facility.
This also updates hacking/test-module to behave similarly.
