+# ADR 1438: Support Conditionals In Composite Actions
+
+**Date**: 2021-10-13
+
+**Status**: Accepted
+
+## Context
+
+We recently shipped composite actions, which allows you to reuse individual steps inside an action. 
+However, one of the [most requested features](https://github.com/actions/runner/issues/834) has been a way to support the `if` keyword.
+
+### Goals
+- We want to keep consistent with current behavior
+- We want to support conditionals via the `if` keyword
+- Our built in functions like `success` should be implementable without calling them, for example you can do `job.status == success` rather then `success()` currently.
+
+### How does composite currently work?
+
+Currently, we have limited conditional support in composite actions for `pre` and `post` steps. 
+These are based on the `job status`, and support keywords like `always()`, `failed()`, `success()` and `cancelled()`. 
+However, generic or main steps do **not** support conditionals.
+
+By default, in a regular workflow, a step runs on the `success()` condition. Which looks at the **job** **status**, sees if it is successful and runs.
+
+By default, in a composite action, main steps run until a single step fails in that composite action, then the composite action is halted early. It does **not** care about the job status.
+Pre, and post steps in composite actions use the job status to determine if they should run.
+
+### How do we go forward?
+
+Well, if we think about what composite actions are currently doing when invoking main steps, they are checking if the current composite action is successful. 
+Lets formalize that concept into a "real" idea.
+
+- We will add an `action_status` field to the github context to mimic the [job's context status](https://docs.github.com/en/actions/learn-github-actions/contexts#job-context).
+  - We have an existing concept that does this `action_path` which is only set for composite actions on the github context.
+- In a composite action during a main step, the `success()` function will check if `action_status == success`, rather then `job_status == success`. Failure will work the same way. 
+  - Pre and post steps in composite actions will not change, they will continue to check the job status.
+
+
+### Nested Scenario
+For nested composite actions, we will follow the existing behavior, you only care about your current composite action, not any parents. 
+For example, lets imagine a scenario with a simple nested composite action
+
+```
+- Job
+  - Regular Step
+  - Composite Action
+    - runs: exit 1
+    - if: always()
+      uses: A child composite action
+        - if: success()
+          runs: echo "this should print"
+        - runs: echo "this should also print"
+    - if: success()
+      runs: echo "this will not print as the current composite action has failed already"
+      
+```
+The child composite actions steps should run in this example, the child composite action has not yet failed, so it should run all steps until a step fails. This is consistent with how a composite action currently works in production if the main job fails but a composite action is invoked with `if:always()` or `if: failure()`
+
+### Other options explored
+We could add the `current_step_status` to the job context rather then `__status` to the steps context, however this comes with two major downsides:
+- We need to support the field for every type of step, because its non trivial to remove a field from the job context once it has been added (its readonly)
+  - For all actions besides composite it would only every be `success`
+  - Its weird to have a `current_step` value on the job context
+- We also explored a `__status` on the steps context.
+  - The `__` is required to prevent us from colliding with a step with id: status
+  - This felt wrong because the naming was not smooth, and did not fit into current conventions.
+
+### Consequences
+- github context has a new field for the status of the current composite action.
+- We support conditional's in composite actions
+- We keep the existing behavior for all users, but allow them to expand that functionality.

+### Troubleshooting: Why can't I configure a runner?
+
+If you are having trouble connecting, try these steps:
+
+1. Validate you can reach our endpoints from your web browser. If not, double check your local network connection
+    - For hosted Github:
+      - https://api.github.com/
+      - https://vstoken.actions.githubusercontent.com/_apis/health
+      - https://pipelines.actions.githubusercontent.com/_apis/health
+    - For GHES/GHAE
+      - https://myGHES.com/_services/vstoken/_apis/health
+      - https://myGHES.com/_services/pipelines/_apis/health
+      - https://myGHES.com/api/v3
+2. Validate you can reach those endpoints in powershell core
+    - The runner runs on .net core, lets validate the local settings for that stack
+    - Open up `pwsh`
+    - Run the command using the urls above `Invoke-WebRequest {url}`
+3. If not, get a packet trace using a tool like wireshark and start looking at the TLS handshake.
+    - If you see a Client Hello followed by a Server RST:
+      - You may need to configure your TLS settings to use the correct version
+        - You should support TLS version 1.2 or later
+      - You may need to configure your TLS settings to have up to date cipher suites, this may be solved by system updates and patches.
+        - Most notably, on windows server 2012 make sure [the tls cipher suite update](https://support.microsoft.com/en-us/topic/update-adds-new-tls-cipher-suites-and-changes-cipher-suite-priorities-in-windows-8-1-and-windows-server-2012-r2-8e395e43-c8ef-27d8-b60c-0fc57d526d94) is installed
+      - Your firewall, proxy or network configuration may be blocking the connection
+      - You will want to reach out to whoever is in charge of your network with these pcap files to further troubleshoot
+    - If you see a failure later in the handshake:
