This has been a focus of the charm audit that we have been performing. Charms are getting flagged for a multitude of reasons that include:
- immutable configuration parameters - ppa's that don't adopt trusty support - general practices we would want to see changed. All these findings are getting filed in launchpad against the charm flagged with the 'audit' tag. If any of these bugs that are found in charms in the wild, I sincerely encourage you to file a bug against the charm so the maintainer has an opportunity to fix it, or properly respond to the situation where they/we can address it. Either through documentation updates, or code contributions. It's also a good practice to get and maintain a pulse check with the charm author, to ensure we're keeping a vibrant and communicating community. As we move forward, there will be a focus on testing charms, and new charms submitted without tests that exercise all parameters of a charm (and verify they are not immutable, for example) would be sent back to the author to be properly tested before inclusion to the store to help mitigate issues like this. I hope this helps clear some of the fog away from the current efforts to ensure we are offering the highest of quality,as we grow the quantity of charms in the store.
