-
-**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 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 treat it as one logical step for the consumer.
-
-A composite action is treated as **one** individual job step (this is known as encapsulation).

-**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 their parents' input variables and nested steps can overwrite the input variables).
-
-### Composite Run Steps Features
-This feature supports at the top action level:
-- name
-- description
-- inputs
-- runs
-- outputs
-
-This feature supports at the run step level:
-- name
-- id
-- run
-- env
-- shell
-- working-directory
-
-This feature **does not support** at the run step level:
-- timeout-minutes
-- secrets
-- conditionals (needs, if, etc.)
-- continue-on-error
-
-### 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
-      shell: bash
-    - run: npm install
-      shell: bash
-```
-
-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. 
-
-### 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. The shell attribute is **required** for each run step because the action author does not know what the workflow author is using for the operating system so we need to explicitly prevent unknown behavior by making sure that each run step has an explicit shell **set by the action author.** On the other hand, `working-directory` is optional. Moreover, the composite action author can map in values from the `inputs` for its `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).
-
-### Running Local Scripts
-
-Example 'workflow.yml':
-```yaml
-jobs:
-  build:
-    runs-on: self-hosted
-    steps:
-    - uses: user/composite@v1
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-runs:
-  using: "composite"
-  steps: 
-    - run: chmod +x ${{ github.action_path }}/test/script2.sh
-      shell: bash
-    - run: chmod +x $GITHUB_ACTION_PATH/script.sh
-      shell: bash
-    - run: ${{ github.action_path }}/test/script2.sh
-      shell: bash
-    - run: $GITHUB_ACTION_PATH/script.sh
-      shell: bash
-```
-Where `user/composite` has the file structure:
-```
-.
-+-- action.yml
-+-- script.sh
-+-- test
-|   +-- script2.sh
-```
-
-
-Users will be able to run scripts located in their action folder by first prepending the relative path and script name with `$GITHUB_ACTION_PATH` or `github.action_path` which contains the path in which the composite action is downloaded to and where those "files" live. Note, you'll have to use `chmod` before running each script if you do not git check in your script files into your github repo with the executable bit turned on.
-
-### 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 }}
-      shell: bash
-```
-
-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 }} 
-    shell: bash
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-outputs:
-  random-number: 
-    description: "Random number"
-    value: ${{ steps.random-number-generator.outputs.random-id }}
-runs:
-  using: "composite"
-  steps: 
-    - id: random-number-generator
-      run: echo "::set-output name=random-id::$(echo $RANDOM)"
-      shell: bash
-```
-
-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's action output(s) are only viewable 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 that 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
-
-**We will not support "Secrets" in a composite action for now. This functionality 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
-
-** `If` and `needs` conditions will not be supported in the composite run steps feature. It will be supported later on in a new feature. **
-
-Old reasoning:
-
-Example `workflow.yml`:
-
-```yaml
-steps:
-  - run: exit 1
-  - uses: user/composite@v1  # <--- this will run, as it's marked as always running
-    if: always()
-```
-
-Example `user/composite/action.yml`:
-
-```yaml
-runs:
-  using: "composite"
-  steps:
-    - run: echo "just succeeding"
-      shell: bash
-    - run: echo "I will run, as my current scope is succeeding"
-      shell: bash
-      if: success()
-    - run: exit 1
-      shell: bash
-    - run: echo "I will not run, as my current scope is now failing"
-      shell: bash
-```
-
-**We will not support "if-condition" in a composite action for now. This functionality will be focused on in a future ADR.**
-
-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** have 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
-      shell: bash
-    - id: foo2
-      run: echo test 2
-      shell: bash
-    - id: foo3
-      run: echo test 3
-      timeout-minutes: 10
-      shell: bash
-```
-
-**We will not support "timeout-minutes" in a composite action for now. This functionality will be focused on in a future ADR.**
-
-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 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 exceeds 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.
-
-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 affect 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
-      shell: bash
-    - run: echo "Hello World 2" <----- This step will run
-      shell: bash
-```
-
-**We will not support "continue-on-error" in a composite action for now. This functionality will be focused on in a future ADR.**
-
-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. 
-
-### 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 representation 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.

-## Common Network Related Issues
-
-### Common things that can cause the runner to not working properly
-
-- Bug in the runner or the dotnet framework that causes actions runner can't make Http request in a certain network environment.
-
-- Proxy/Firewall block certain HTTP method, like it block all POST and PUT calls which the runner will use to upload logs.
-
-- Proxy/Firewall only allows requests with certain user-agent to pass through and the actions runner user-agent is not in the allow list.
-
-- Proxy try to decrypt and exam HTTPS traffic for security purpose but cause the actions-runner to fail to finish SSL handshake due to the lack of trusting proxy's CA.
-
-- Proxy try to modify the HTTPS request (like add or change some http headers) and causes the request become incompatible with the Actions Service (ASP.NetCore), Ex: [Nginx](https://github.com/dotnet/aspnetcore/issues/17081)
-
-- Firewall rules that block action runner from accessing certain hosts, ex: `*.github.com`, `*.actions.githubusercontent.com`, etc.
-
-
-### Identify and solve these problems
-
-The key is to figure out where is the problem, the network environment, or the actions runner?
-
-Use a 3rd party tool to make the same requests as the runner did would be a good start point.
-
-- Use `nslookup` to check DNS
-- Use `ping` to check Ping
-- Use `traceroute`, `tracepath`, or `tracert` to check the network route between the runner and the Actions service 
-- Use `curl -v` to check the network stack, good for verifying default certificate/proxy settings.
-- Use `Invoke-WebRequest` from `pwsh` (`PowerShell Core`) to check the dotnet network stack, good for verifying bugs in the dotnet framework.
-
-If the 3rd party tool is also experiencing the same error as the runner does, then you might want to contact your network administrator for help.

-## SSL Certificate Related Issues
-
-You might run into an SSL certificate error when your GitHub Enterprise Server is using a self-signed SSL server certificate or a web proxy within your network is decrypting HTTPS traffic for a security audit.
-
-As long as your certificate is generated properly, most of the issues should be fixed after your trust the certificate properly on the runner machine.
-
-> Different OS might have extra requirements on SSL certificate,
-> Ex: macOS requires `ExtendedKeyUsage` https://support.apple.com/en-us/HT210176
-
-### Don't skip SSL cert validation
-
-> !!! DO NOT SKIP SSL CERT VALIDATION !!!  
-> !!! IT IS A BAD SECURITY PRACTICE !!!  
-
-### Download SSL certificate chain 
-
-Depends on how your SSL server certificate gets configured, you might need to download the whole certificate chain from a machine that has trusted the SSL certificate's CA.
-
-- Approach 1: Download certificate chain using a browser (Chrome, Firefox, IT), you can google for more example, [here is what I found](https://medium.com/@menakajain/export-download-ssl-certificate-from-server-site-url-bcfc41ea46a2)
-
-- Approach 2: Download certificate chain using OpenSSL, you can google for more example, [here is what I found](https://superuser.com/a/176721)
-
-- Approach 3: Ask your network administrator or the owner of the CA certificate to send you a copy of it
-
-### Trust CA certificate for the Runner
-
-The actions runner is a dotnet core application which will follow how dotnet load SSL CA certificates on each OS.
-
-You can get full details documentation at [here](https://docs.microsoft.com/en-us/dotnet/standard/security/cross-platform-cryptography#x509store)
-
-In short: 
-- Windows: Load from Windows certificate store.
-- Linux: Load from OpenSSL CA cert bundle.
-- macOS: Load from macOS KeyChain.
-
-To let the runner trusts your CA certificate, you will need to:
-1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.

-### Trust CA certificate for Git CLI
-
-Git uses various CA bundle file depends on your operation system.
-- Git packaged the CA bundle file within the Git installation on Windows 
-- Git use OpenSSL certificate CA bundle file on Linux and macOS
-
-You can check where Git check CA file by running:
-```bash
-export GIT_CURL_VERBOSE=1
-git ls-remote https://github.com/actions/runner HEAD
-```
-
-You should see something like:
-```
-* Couldn't find host github.com in the .netrc file; using defaults
-*   Trying 140.82.114.4...
-* TCP_NODELAY set
-* Connected to github.com (140.82.114.4) port 443 (#0)
-* ALPN, offering h2
-* ALPN, offering http/1.1
-* successfully set certificate verify locations:
-*   CAfile: /etc/ssl/cert.pem
-  CApath: none
-* SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256
-```
-This tells me `/etc/ssl/cert.pem` is where it read trusted CA certificates.
-
-To let Git trusts your CA certificate, you will need to:
-1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
-2. Set `http.sslCAInfo` Git config or `GIT_SSL_CAINFO` environment variable to the full path of the `.pem` file [Git Doc](https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpsslCAInfo)
-> I would recommend using `http.sslCAInfo` since it can be scope to certain hosts that need the extra trusted CA.  
-> Ex: `git config --global http.https://myghes.com/.sslCAInfo /extra/ca/cert.pem`  
-> This will make Git use the `/extra/ca/cert.pem` only when communicates with `https://myghes.com` and keep using the default CA bundle with others.

-### Trust CA certificate for Node.js
-
-Node.js has compiled a snapshot of the Mozilla CA store that is fixed at each version of Node.js' release time.
-
-To let Node.js trusts your CA certificate, you will need to:
-1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
-2. Set environment variable `NODE_EXTRA_CA_CERTS` which point to the file. ex: `export NODE_EXTRA_CA_CERTS=/full/path/to/cacert.pem` or `set NODE_EXTRA_CA_CERTS=C:\full\path\to\cacert.pem`

-## Quickstart: Run a job from a real repository
-
-If you just want to get from building the sourcecode to using it to execute an action, you will need:
-
-- The url of your repository
-- A runner registration token. You can find it at `https://github.com/{your-repo}/settings/actions/runners/new`
-
-
-```bash
-git clone https://github.com/actions/runner
-cd runner/src
-./dev.(sh/cmd) layout # the runner that built from source is in {root}/_layout
-cd ../_layout
-./config.(sh/cmd) --url https://github.com/{your-repo} --token ABCABCABCABCABCABCABCABCABCAB # accept default name, labels and work folder
-./run.(sh/cmd)
-```
-
-If you trigger a job now, you can see the runner execute it.
-
-Tip: Make sure your job can run on this runner. The easiest way is to set `runs-on: self-hosted` in the workflow file.
-

-Let's break that down.
-
-### Clone repository:
-
-```bash
-git clone https://github.com/actions/runner
-cd runner
-```
-If you want to push your changes to a remote, it is recommended you fork the repository and use that fork as your origin instead of `https://github.com/actions/runner`.
-
-
-### Build Layout:
-
-This command will build all projects, then copies them and other dependencies into a folder called `_layout`. The binaries in this folder are then used for running, debugging the runner.
-
-```bash
-cd ./src # execute the script from this folder
-./dev.(sh/cmd) layout # the runner that built from source is in {root}/_layout
-```
-
-If you make code changes after this point, use the argument `build` to build your code in the `src` folder to keep your `_layout` folder up to date.
-
-```bash
-cd ./src
-./dev.(sh/cmd) build # {root}/_layout will get updated
-```
-### Test Layout:
-
-This command runs the suite of unit tests in the project
-
-```bash
-cd ./src
-./dev.(sh/cmd) test # run all unit tests before git commit/push

-
-### Configure Runner:
-
-If you want to manually test your runner and run actions from a real repository, you'll have to configure it before running it.
-
-```bash
-cd runner/_layout
-./config.(sh/cmd) # configure your custom runner
-```
-
-You will need your the name of your repository and a runner registration token.
-Check [Quickstart](##Quickstart:-Run-a-job-from-a-real-repository) if you don't know how to get this token.
-
-These can also be passed down as arguments to `config.(sh/cmd)`:
-```bash
-cd runner/_layout
-./config.(sh/cmd) --url https://github.com/{your-repo} --token ABCABCABCABCABCABCABCABCABCAB
-```
-
-### Run Runner
-
-All that's left to do is to start the runner:
-```bash
-cd runner/_layout
-./run.(sh/cmd) # run your custom runner

-```bash
-cd runner/_layout/_diag

-# Development Life Cycle using VS Code:
-
-These examples use VS Code, but the idea should be similar across all IDEs as long as you attach to the same processes in the right folder.
-## Configure
-
-To successfully start the runner, you need to register it using a repository and a runner registration token.
-Run `Configure` first to build the source code and set up the runner in `_layout`. 
-Once it's done creating `_layout`, it asks for the url of your repository and your token in the terminal.
-
-Check [Quickstart](../contribute.md#quickstart-run-a-job-from-a-real-repository) if you don't know how to get this token.
-
-## Debugging
-
-Debugging the full lifecycle of a job can be tricky, because there are multiple processes involved.
-All the configs below can be found in `.vscode/launch.json`.
-
-## Debug the Listener
-
-```json
-{
-    "name": "Run [build]",
-    "type": "coreclr",
-    "request": "launch",
-    "preLaunchTask": "build runner layout",  // use the config called "Run" to launch without rebuild
-    "program": "${workspaceFolder}/_layout/bin/Runner.Listener",
-    "args": [
-        "run" // run without args to print usage
-    ],
-    "cwd": "${workspaceFolder}/src",
-    "console": "integratedTerminal",
-    "requireExactSource": false,
-}
-```
-
-If you launch `Run` or `Run [build]`, it starts a process called `Runner.Listener`.
-This process will receive any job queued on this repository if the job runs on matching labels (e.g `runs-on: self-hosted`).
-Once a job is received, a `Runner.Listener` starts a new process of `Runner.Worker`. 
-Since this is a diferent process, you can't use the same debugger session debug it.
-Instead, a parallel debugging session has to be started, using a different launch config.
-Luckily, VS Code supports multiple parallel debugging sessions.
-
-## Debug the Worker
-
-Because the worker process is usually started by the listener instead of an IDE, debugging it from start to finish can be tricky.
-For this reason, `Runner.Worker` can be configured to wait for a debugger to be attached before it begins any actual work.
-
-Set the environment variable `GITHUB_ACTIONS_RUNNER_ATTACH_DEBUGGER` to `true` or `1` to enable this wait.
-All worker processes now will wait 20 seconds before they start working on their task. 
-
-This gives enough time to attach a debugger by running `Debug Worker`.
-If for some reason you have multiple workers running, run the launch config `Attach` instead.
-Select `Runner.Worker` from the running processes when VS Code prompts for it.
