New module.run format causing traceback from state file

[sdodsley]

Description of Issue/Question

Trying to use the new module.run format and getting a traceback failure from the minion.

I have followed the instructions regarding the new format and including the required settings in the minion config file

Setup

Minion config file contains the following:

use_superseded:
  - module.run

top.sls

base:
  '*':
    - storage

storage.sls

storage:
  module.run:
    - test.echo:
      - text: "Hello"

Steps to Reproduce Issue

# salt sn1-pool-e01-15.puretec.purestorage.com state.highstate
sn1-pool-e01-15.puretec.purestorage.com:

I am unable to replicate this issue, but I do see another one right now, on the 2017.7 branch.

@isbm can you take a look at this?

Thanks,

It appears that this is broken by ea83513

[sdodsley]

@gtmanfred so are you saying that my original issue is also caused by this, or are we now looking at a different issue?

[gtmanfred]

In general it seems like module.run doesn't seem to be working right now, and should be looked at.

[aneeshusa]

@sdodsley Your original issue is coming from a new lint I added in #43070; it looks like module.run has a non-standard return format, which the new code is trapping on. Long term it would be good to update module.run to fix this, but I'm not sure how much effort that is.

In the meantime, it may be prudent to lower the verify_ret_for_export lint from a hard exception to a logged warning; I suggested this in my PR since I had run into some other misbehaving modules there, and I'm not sure how many similar issues are still lurking. We could also leave it as-is and fix any bug reports as they come in, if there are likely only a few.

[sdodsley]

@aneeshusa looks like the module.run old format is going to be deprecated in Oxygen and the method failing here will be the default I think we need to at the very least fix the lint to be a warning. This will allow malformed responses to be tracked and fixed at a later date.

[gtmanfred]

The old format is being deprecated in Selenium. We are working on fixing this before 2017.7.2 is out, and then we will also be fixing it in develop, which is where you are seeing it fail.

@gtmanfred Is Selenium after Fluorine? The Nitrogen release notes say this is being deprecated in Oxygen.
