-# ADR 361: Wrapper Action
-
-**Date**: 2020-03-06
-
-**Status**: Pending
-
-## Context
-
-In addition to action's regular execution, action author may wants their action has a chance to participate in:
-- Job initialize  
-  My Action will collect machine resource usage (CPU/RAM/Disk) during a workflow job execution, we need to start perf recorder at the begin of the job.
-- Job cleanup  
-  My Action will dirty local workspace or machine environment during execution, we need to cleanup these changes at the end of the job.  
-  Ex: `actions/checkout@v2` will write `github.token` into local `.git/config` during execution, it has post job cleanup defined to undo the changes.
-
-## Decision
-
-### Add `pre` and `post` execution to action
-
-Node Action Example:
-
-```yaml
- name: 'My action with pre'
- description: 'My action with pre'
- runs:
-   using: 'node12'
-   pre: 'setup.js'
-   pre-if: 'success()' // Optional
-   main: 'index.js'
-   post: 'cleanup.js'
-   post-if: 'success()' // Optional
-```
-
-Container Action Example:
-
-```yaml
- name: 'My action with pre'
- description: 'My action with pre'
- runs:
-   using: 'docker'
-   image: 'mycontainer:latest'
-   pre-entrypoint: 'setup.sh'
-   pre-if: 'success()' // Optional
-   entrypoint: 'entrypoint.sh'
-   post-entrypoint: 'cleanup.sh'
-   post-if: 'success()' // Optional
-```
-
-Both `pre` and `post` will has default `pre-if/post-if` sets to `always()`.  
-Setting `pre` to `always()` will make sure no matter what condition evaluate result the `main` gets at runtime, the `pre` has always run already.   
-`pre` executes in order of how the steps are defined.  
-`pre` will always be added to job steps list during job setup.  
-> Action referenced from local repository (`./my-action`) won't get `pre` setup correctly since the repository haven't checkout during job initialize.  
-> We can't use GitHub api to download the repository since there is a about 3 mins delay between `git push` and the new commit available to download using GitHub api.
-
-`post` will be pushed into a `poststeps` stack lazily when the action's `pre` or `main` execution passed `if` condition check and about to run, you can't have an action that only contains a `post`, we will pop and run each `post` after all `pre` and `main` finished.
-> Currently `post` works for both repository action (`org/repo@v1`) and local action (`./my-action`)
-
-Valid action:
-- only has `main`
-- has `pre` and `main`
-- has `main` and `post`
-- has `pre`, `main` and `post`
-
-Invalid action:
-- only has `pre`
-- only has `post`
-- has `pre` and `post`
-
-Potential downside of introducing `pre`:
-
-- Extra magic wrt step order. Users should control the step order. Especially when we introduce templates.  
-- Eliminates the possibility to lazily download the action tarball, since `pre` always run by default, we have to download the tarball to check whether action defined a `pre`  
-- `pre` doesn't work with local action, we suggested customer use local action for testing their action changes, ex CI for their action, to avoid delay between `git push` and GitHub repo tarball download api.  
-- Condition on the `pre` can't be controlled using dynamic step outputs. `pre` executes too early.

-# ADR 0397: Support adding custom labels during runner config
-**Date**: 2020-03-30
-
-**Status**: Approved
-
-## Context
-
-Since configuring self-hosted runners is commonly automated via scripts, the labels need to be able to be created during configuration.  The runner currently registers the built-in labels (os, arch) during registration but does not accept labels via command line args to extend the set registered.
-
-See Issue: https://github.com/actions/runner/issues/262
-
-This is another version of [ADR275](https://github.com/actions/runner/pull/275)
-
-## Decision
-
-This ADR proposes that we add a `--labels` option to `config`, which could be used to add custom additional labels to the configured runner.
-
-For example, to add a single extra label the operator could run:
-```bash
-./config.sh --labels mylabel
-```
-> Note: the current runner command line parsing and envvar override algorithm only supports a single argument (key).
-
-This would add the label `mylabel` to the runner, and enable users to select the runner in their workflow using this label:
-```yaml
-runs-on: [self-hosted, mylabel]
-```
-
-To add multiple labels the operator could run:
-```bash
-./config.sh --labels mylabel,anotherlabel
-```
-> Note: the current runner command line parsing and envvar override algorithm only supports a single argument (key).
-
-This would add the label `mylabel` and `anotherlabel` to the runner, and enable users to select the runner in their workflow using this label:
-```yaml
-runs-on: [self-hosted, mylabel, anotherlabel]
-```
-
-It would not be possible to remove labels from an existing runner using `config.sh`, instead labels would have to be removed using the GitHub UI.
-
-The labels argument will split on commas, trim and discard empty strings.  That effectively means don't use commans in unattended config label names.  Alternatively we could choose to escape commans but it's a nice to have.
-
-## Replace
-
-If an existing runner exists and the option to replace is chosen (interactively of via unattend as in this scenario), then the labels will be replaced / overwritten (not merged).
-
-## Overriding built-in labels
-
-Note that it is possible to register "built-in" hosted labels like `ubuntu-latest` and is not considered an error.  This is an effective way for the org / runner admin to dictate by policy through registration that this set of runners will be used without having to edit all the workflow files now and in the future.
-
-We will also not make other restrictions such as limiting explicitly adding os / arch labels and validating.  We will assume that explicit labels were added for a reason and not restricting offers the most flexibility and future proofing / compat.
-
-## Consequences
-
-The ability to add custom labels to a self-hosted runner would enable most scenarios where job runner selection based on runner capabilities or characteristics are required.

-# ADR 0549: Composite Run Steps
-
-**Date**: 2020-06-17
-
-**Status**: Accepted
-
-## Context
-
-Customers want to be able to compose actions from actions (ex: https://github.com/actions/runner/issues/438)
-
-An important step towards meeting this goal is to build in functionality for actions where users can simply execute any number of steps. 
-
-### Guiding Principles
-
-We don't want the workflow author to need to know how the internal workings of the action work. Users shouldn't know the internal workings of the composite action (for example, `default.shell` and `default.workingDir` should not be inherited from the workflow file to the action file). When deciding how to design certain parts of composite run steps, we want to think one logical step from the consumer.
-
-A composite action is treated as **one** individual job step (this is known as encapsulation).
-
-
-## Decision
-
-**In this ADR, we only support running multiple run steps in an Action.** In doing so, we build in support for mapping and flowing the inputs, outputs, and env variables (ex: All nested steps should have access to its parents' input variables and nested steps can overwrite the input variables).
-
-### Steps
-
-Example `workflow.yml`
-
-```yaml
-jobs:
-  build:
-    runs-on: self-hosted
-    steps:
-    - id: step1
-      uses: actions/setup-python@v1
-    - id: step2
-      uses: actions/setup-node@v2
-    - uses: actions/checkout@v2
-    - uses: user/composite@v1
-    - name: workflow step 1
-      run: echo hello world 3
-    - name: workflow step 2
-      run: echo hello world 4
-```
-
-Example `user/composite/action.yml`
-
-```yaml
-runs:
-  using: "composite"
-  steps:
-    - run: pip install -r requirements.txt
-    - run: npm install
-```
-
-Example Output
-
-```yaml
-[npm installation output]
-[pip requirements output]
-echo hello world 3
-echo hello world 4
-```
-
-We add a token called "composite" which allows our Runner code to process composite actions. By invoking "using: composite", our Runner code then processes the "steps" attribute, converts this template code to a list of steps, and finally runs each run step sequentially. If any step fails and there are no `if` conditions defined, the whole composite action job fails. 
-
-### Inputs
-
-Example `workflow.yml`:
-
-```yaml
-steps: 
-  - id: foo
-    uses: user/composite@v1
-    with:
-      your_name: "Octocat"
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-inputs:
-  your_name:
-    description: 'Your name'
-    default: 'Ethan'
-runs:
-  using: "composite"
-  steps: 
-    - run: echo hello ${{ inputs.your_name }}
-```
-
-Example Output:
-
-```
-hello Octocat
-```
-
-Each input variable in the composite action is only viewable in its own scope.
-
-### Outputs
-
-Example `workflow.yml`:
-
-```yaml
-...
-steps: 
-  - id: foo
-    uses: user/composite@v1
-  - run: echo random-number ${{ steps.foo.outputs.random-number }} 
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-outputs:
-  random-number: 
-    description: "Random number"
-    value: ${{ steps.random-number-generator.outputs.random-id }}
-runs:
-  using: "composite"
-  steps: 
-    - id: random-number-generator
-      run: echo "::set-output name=random-number::$(echo $RANDOM)"
-```
-
-Example Output:
-
-```
-::set-output name=my-output::43243
-random-number 43243
-```
-
-Each of the output variables from the composite action is viewable from the workflow file that uses the composite action. In other words, every child action output(s) is viewable only by its parent using dot notation (ex `steps.foo.outputs.random-number`).
-
-Moreover, the output ids are only accessible within the scope where it was defined. Note that in the example above, in our `workflow.yml` file, it should not have access to output id (i.e. `random-id`). The reason why we are doing this is because we don't want to require the workflow author to know the internal workings of the composite action.
-
-### Context
-
-Similar to the workflow file, the composite action has access to the [same context objects](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#contexts) (ex: `github`, `env`, `strategy`). 
-
-### Environment
-
-In the Composite Action, you'll only be able to use `::set-env::` to set environment variables just like you could with other actions.
-
-### Secrets
-
-**Note** : This feature will be focused on in a future ADR.
-
-We'll pass the secrets from the composite action's parents (ex: the workflow file) to the composite action. Secrets can be created in the composite action with the secrets context. In the actions yaml, we'll automatically mask the secret. 
-
-
-### If Condition
-
-Example `workflow.yml`:
-
-```yaml
-steps:
-  - run: exit 1
-  - uses: user/composite@v1  # <--- this will run, as it's marked as always runing
-    if: always()
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-runs:
-  using: "composite"
-  steps:
-    - run: echo "just succeeding"
-    - run: echo "I will run, as my current scope is succeeding"
-      if: success()
-    - run: exit 1
-    - run: echo "I will not run, as my current scope is now failing"
-```
-
-See the paragraph below for a rudimentary approach (thank you to @cybojenix for the idea, example, and explanation for this approach):
-
-The `if` statement in the parent (in the example above, this is the `workflow.yml`) shows whether or not we should run the composite action. So, our composite action will run since the `if` condition for running the composite action is `always()`.
-
-**Note that the if condition on the parent does not propagate to the rest of its children though.**
-
-In the child action (in this example, this is the `action.yml`), it starts with a clean slate (in other words, no imposing if conditions). Similar to the logic in the paragraph above, `echo "I will run, as my current scope is succeeding"` will run since the `if` condition checks if the previous steps **within this composite action** has not failed. `run: echo "I will not run, as my current scope is now failing"` will not run since the previous step resulted in an error and by default, the if expression is set to `success()` if the if condition is not set for a step.
-
-
-What if a step has `cancelled()`? We do the opposite of our approach above if `cancelled()` is used for any of our composite run steps. We will cancel any step that has this condition if the workflow is cancelled at all.
-    
-### Timeout-minutes
-
-Example `workflow.yml`:
-
-```yaml
-steps: 
-  - id: bar
-    uses: user/test@v1
-    timeout-minutes: 50
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-runs:
-  using: "composite"
-  steps: 
-    - id: foo1
-      run: echo test 1
-      timeout-minutes: 10
-    - id: foo2
-      run: echo test 2
-    - id: foo3
-      run: echo test 3
-      timeout-minutes: 10
-```
-
-A composite action in its entirety is a job. You can set both timeout-minutes for the whole composite action or its steps as long as the the sum of the `timeout-minutes` for each composite action step that has the attribute `timeout-minutes` is less than or equals to `timeout-minutes` for the composite action. There is no default timeout-minutes for each composite action step. 
-
-If the time taken for any of the steps in combination or individually exceed the whole composite action `timeout-minutes` attribute, the whole job will fail (1). If an individual step exceeds its own `timeout-minutes` attribute but the total time that has been used including this step is below the overall composite action `timeout-minutes`, the individual step will fail but the rest of the steps will run based on their own `timeout-minutes` attribute (they will still abide by condition (1) though).
-
-For reference, in the example above, if the composite step `foo1` takes 11 minutes to run, that step will fail but the rest of the steps, `foo1` and `foo2`, will proceed as long as their total runtime with the previous failed `foo1` action is less than the composite action's `timeout-minutes` (50 minutes). If the composite step `foo2` takes 51 minutes to run, it will cause the whole composite action job to fail. I
-
-The rationale behind this is that users can configure their steps with the `if` condition to conditionally set how steps rely on each other. Due to the additional capabilities that are offered with combining `timeout-minutes` and/or `if`, we wanted the `timeout-minutes` condition to be as dumb as possible and not effect other steps. 
-
-[Usage limits still apply](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions?query=if%28%29#usage-limits)
-
-
-### Continue-on-error
-
-Example `workflow.yml`:
-
-```yaml
-steps: 
-  - run: exit 1
-  - id: bar
-    uses: user/test@v1
-    continue-on-error: false
-  - id: foo
-    run: echo "Hello World" <------- This step will not run
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-runs:
-  using: "composite"
-  steps: 
-    - run: exit 1
-      continue-on-error: true
-    - run: echo "Hello World 2" <----- This step will run
-```
-
-If any of the steps fail in the composite action and the `continue-on-error` is set to `false` for the whole composite action step in the workflow file, then the steps below it will run. On the flip side, if `continue-on-error` is set to `true` for the whole composite action step in the workflow file, the next job step will run.
-
-For the composite action steps, it follows the same logic as above. In this example, `"Hello World 2"` will be outputted because the previous step has `continue-on-error` set to `true` although that previous step errored. 
-
-### Defaults
-We will not support "defaults" in a composite action. 
-
-### Shell and Working-directory
-For each run step in a composite action, the action author can set the `shell` and `working-directory` attributes for that step. These attributes are optional for each run step - by default, the `shell` is set to whatever default value is associated with the runner os (ex: bash =\> Mac). Moreover, the composite action author can map in values from the `inputs` for it's `shell` and `working-directory` attributes at the step level for an action. 
-
-For example,
-
-`action.yml`
-
-
-```yaml
-inputs:
-  shell_1:
-    description: 'Your name'
-    default: 'pwsh'
-steps:
-  - run: echo 1
-    shell: ${{ inputs.shell_1 }}
-```
-
-Note, the workflow file and action file are treated as separate entities. **So, the workflow `defaults` will never change the `shell` and `working-directory` value in the run steps in a composite action.** Note, `defaults` in a workflow only apply to run steps not "uses" steps (steps that use an action).
-
-### Visualizing Composite Action in the GitHub Actions UI
-We want all the composite action's steps to be condensed into the original composite action node. 
-
-Here is a visual represenation of the [first example](#Steps)
-
-```yaml
-| composite_action_node |
-    | echo hello world 1 | 
-    | echo hello world 2 |
-| echo hello world 3 | 
-| echo hello world 4 |
-
-```
-
-
-## Consequences
-
-This ADR lays the framework for eventually supporting nested Composite Actions within Composite Actions. This ADR allows for users to run multiple run steps within a GitHub Composite Action with the support of inputs, outputs, environment, and context for use in any steps as well as the if, timeout-minutes, and the continue-on-error attributes for each Composite Action step.
