## Summary
Fixes critical bugs found during testing of the rule notification.
* Fixes a bug where when you turn on rules quickly such as ML rules you would see these message below. This message can also be seen when you first create a rule with an action notification. This is a race condition with how we update rules multiple times when we really should only update it once and do it before enabling a rule
```
server log [12:18:35.986] [error][alerting][alerting][plugins][plugins] Executing Alert "63b828b5-24b9-4d55-83ee-8a8201fe2d76" has resulted in Error: [security_exception] missing authentication credentials for REST request [/_security/user/_has_privileges], with { header={ WWW-Authenticate={ 0="Bearer realm=\"security\"" & 1="ApiKey" & 2="Basic realm=\"security\" charset=\"UTF-8\"" } }
```
* Fixes a bug where we were using `ruleParams.interval` when we should have been using `ruleAlertSavedObject.attributes.schedule.interval`. When changing rule notifications to run daily, weekly, etc.. you would see this exception being thrown:
```
server log [21:23:08.028] [error][alerting][alerting][plugins][plugins] Executing Alert "fedcccc0-7c69-4e2f-83f8-d8ee88ab5484" has resulted in Error: "from" or "to" was not provided to signals count query
```
* Fixes misc typing issues found
* Fixes it to where we no longer make multiple DB calls but rather pass down objects we already have.
* Changes the work flow to where we only update, create, or patch the alerting object once which fixes the race condition and improves the backend performance.
* Removes left over unused code
* Applied https://en.wikipedia.org/wiki/Single-entry_single-exit to functions where it made sense and easier to read.

Getting Started
If you just want to try Kibana out, check out the Elastic Stack Getting Started Page to give it a whirl.
If you're interested in diving a bit deeper and getting a taste of Kibana's capabilities, head over to the Kibana Getting Started Page.
Using a Kibana Release
If you want to use a Kibana release in production, give it a test run, or just play around:
- Download the latest version on the Kibana Download Page.
- Learn more about Kibana's features and capabilities on the Kibana Product Page.
- We also offer a hosted version of Kibana on our Cloud Service.
Building and Running Kibana, and/or Contributing Code
You might want to build Kibana locally to contribute some code, test out the latest features, or try out an open PR:
- CONTRIBUTING.md will help you get Kibana up and running.
- If you would like to contribute code, please follow our STYLEGUIDE.md.
- Learn more about our UI code with UI_SYSTEMS.md.
- For all other questions, check out the FAQ.md and wiki.
Documentation
Visit Elastic.co for the full Kibana documentation.
For information about building the documentation, see the README in elastic/docs.
Version Compatibility with Elasticsearch
Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.
Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.
| Situation | Example Kibana version | Example ES version | Outcome |
|---|---|---|---|
| Versions are the same. | 5.1.2 | 5.1.2 | 💚 OK |
| ES patch number is newer. | 5.1.2 | 5.1.5 | ⚠️ Logged warning |
| ES minor number is newer. | 5.1.2 | 5.5.0 | ⚠️ Logged warning |
| ES major number is newer. | 5.1.2 | 6.0.0 | 🚫 Fatal error |
| ES patch number is older. | 5.1.2 | 5.1.0 | ⚠️ Logged warning |
| ES minor number is older. | 5.1.2 | 5.0.0 | 🚫 Fatal error |
| ES major number is older. | 5.1.2 | 4.0.0 | 🚫 Fatal error |
