This commit address a bug in the ios_config module when using the
match: strict argument. When the argument is used, the module will
compare the configuration block same as match: exact which is not the
intended behavior. This commit updates the behavior to propertly handle
the strict argument.
now uses atomic move to avoid data corruption
correclty cleans up temp files in every case
returns backup_file info if needed
validate validate before temp file gets created
backup AFTER validate
Without this change, a download failure may bail out with the message:
"Failure downloading http://foo/bar, 'NoneType' object has no attribute 'read'"
whereas with this fix, you'd get a proper error like:
"Failure downloading http://foo/bar, Request failed: <urlopen error [Errno 113] No route to host>"
or one of the many other possible download errors that can occur.
The returned list of diffs aims to simulate how a file system diff would
look before and after writing the sources list files.
n.b. Ternary conditional is due to failing integration test for
python 2.4
This commit refactors the arugments used in ops_template to be strictly
typed and handle by declarative / rest and cli based configurations. It
also removes old arguments not supported and cleans up the documentation
strings
This mirrors a nearly identical change made to apt_repository.py.
Also removes the use of apt-get --force-yes as it can be dangerous
and should not be necessary (apt_repository.py does not use it).
Repeating the explanation from the apt_respository change below:
Since use_unsafe_shell is suspicious from a security point
of view (or it wouldn't be unsafe), the less we have, the less
code we have to thoroughly inspect for a security audit.
In this case, the '&&' can be replaced by doing 2 calls to run_command.
Running async_status in an "until: result.finished" loop will mask a module failure (eg, traceback) with a
template failure, because the fail dict doesn't include "finished" (eg, you'll see "ERROR! The conditional check 'bogus_out.finished' failed. The error was: ERROR! error while evaluating conditional: bogus_out.finished ({% if bogus_out.finished %} True {% else %} False {% endif %}"). Because the failure dict still includes "failed: true",
this change has no effect on stoppage/failure reporting, it just prevents the common usage pattern from masking the underlying error message.
Since our validation does conversion as well as validation, I'm not sure
this is entirely correct. May need to take a look at our conversion
code and re-examine to be sure we're doing it right.
