Without allow_unicode=True, unicode characters are processed through the
str representer and on Python 2 are dumped as a Unicode code point (i.e.
a literal \u0414). This commit makes allow_unicode=True the default in
our salt.utils.yamlloader.safe_dump() helper. It also adds a new
salt.utils.yamlloader.dump() helper which wraps yaml.dump() and also
makes allow_unicode=True the default.
To make importing and using our custom yaml loader/dumper easier, a
convenience module called salt.utils.yaml has been added, which does a
wildcard import from both salt.utils.yamldumper and
salt.utils.yamlloader.
Refs to yaml.load/dump and yaml.safe_load/safe_dump have been updated to
salt.utils.yaml, to ensure that unicode is handled properly.
Some states are complicated and multiple subparts,
or maybe cross-call into __states__ if they manage subresources.
In these cases, they will have multiple comments.
Make this more ergonomic by supporting a list of strings as the
value for ret['comment'] in state returns and documenting this.
By joining comments on newlines, it is possible to combine
single-line and multi-line comments cleanly, as opposed to e.g. commas.
The driving impetus for this is some of the boto modules.
An update to the boto_sqs module is included as an example.
Add a check that outgoing state return data has the right shape,
and add a testcase as well.
Fix the NPM state tests and the saltmod runner & wheel state functions
to comply with the prescribed format.
Headline changes:
- Move to boto3
- Use result-style error handling
- Optimize number of API calls:
- Set attributes at creation time
- Set all attributes in one API call
- Show diff when attribute changes detected
