unset GTIHUB_ACTION_REPOSITORY and GITHUB_ACTION_REF for non-repo based actions.

* add `workflow_dispatch`

* Add an environment variable to indicate which repository the currently running Action came from.

* Expose the Action ref as well.

* Move setting `github.action_repository` and `github.action_ref` to `ActionRunner.cs`.

* Don't set `action_repository` and `action_ref` for local Actions.

 [![Actions Status](https://github.com/actions/runner/workflows/Runner%20CI/badge.svg)](https://github.com/actions/runner/actions)
 
+The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the [hosted virtual environments](https://github.com/actions/virtual-environments), or you can [self-host the runner](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners) in your own environment.
+
 ## Get Started

+# ADR 263: Self Hosted Runner Proxies
+
+**Date**: 2019-11-13
+
+**Status**: Accepted
+
+## Context
+
+- Proxy support is required for some enterprises and organizations to start using their own self hosted runners
+- While there is not a standard convention, many applications support setting proxies via the environmental variables `http_proxy`, `https_proxy`, `no_proxy`, such as curl, wget, perl, python, docker, git, R, ect
+  - Some of these applications use `HTTPS_PROXY` versus `https_proxy`, but most understand or primarily support the lowercase variant
+
+## Decision
+
+We will update the Runner to use the conventional environment variables for proxies: `http_proxy`, `https_proxy` and `no_proxy` if they are set.
+These are described in detail below:
+- `https_proxy` a proxy URL for all https traffic. It may contain basic authentication credentials. For example:
+  - http://proxy.com
+  - http://127.0.0.1:8080
+  - http://user:password@proxy.com
+- `http_proxy` a proxy URL for all http traffic. It may contain basic authentication credentials. For example:
+  - http://proxy.com
+  - http://127.0.0.1:8080
+  - http://user:password@proxy.com
+- `no_proxy` a comma separated list of hosts that should not use the proxy. An optional port may be specified
+  - `google.com`
+  - `yahoo.com:443`
+  - `google.com,bing.com`
+
+We won't use `http_proxy` for https traffic when `https_proxy` is not set, this behavior lines up with any libcurl based tools (curl, git) and wget.
+Otherwise action authors and workflow users need to adjust to differences between the runner proxy convention, and tools used by their actions and scripts.  
+
+Example:  
+  Customer set `http_proxy=http://127.0.0.1:8888` and configure the runner against `https://github.com/owner/repo`, with the `https_proxy` -> `http_proxy` fallback, the runner will connect to the server without any problem. However, if a user runs `git push` to `https://github.com/owner/repo`, `git` won't use the proxy since it requires `https_proxy` to be set for any https traffic.
+
+> `golang`, `node.js` and other dev tools from the linux community use `http_proxy` for both http and https traffic based on my research.
+
+A majority of our users are using Linux where these variables are commonly required to be set by various programs. By reading these values, we simplify the process for self hosted runners to set up proxy, and expose it in a way users are already familiar with.
+
+A password provided for a proxy will be masked in the logs.
+
+We will support the lowercase and uppercase variants, with lowercase taking priority if both are set.
+
+### No Proxy Format
+
+While exact implementations are different per application on handle `no_proxy` env, most applications accept a comma separated list of hosts. Some accept wildcard characters (*). We are going to do exact case-insensitive matches, and not support wildcards at this time.
+For example:
+- example.com will match example.com, foo.example.com, foo.bar.example.com
+- foo.example.com will match bar.foo.example.com and foo.example.com
+
+We will not support IP addresses for `no_proxy`, only hostnames.
+
+## Consequences
+
+1. Enterprises and organizations needing proxy support will be able to embrace self hosted runners
+2. Users will need to set these environmental variables before configuring the runner in order to use a proxy when configuring
+3. The runner will read from the environmental variables during config and runtime and use the provided proxy if it exists
+4. Users may need to pass these environmental variables into other applications if they do not natively take these variables
+5. Action authors may need to update their workflows to react to the these environment variables
+6. We will document the way of setting environmental variables for runners using the environment variables and how the runner uses them
+7. Like all other secrets, users will be able to relatively easily figure out proxy password if they can modify a workflow file running on a self hosted machine

+# ADR 0274: Step outcome and conclusion
+
+**Date**: 2020-01-13
+
+**Status**: Accepted
+
+## Context
+
+This ADR proposes adding `steps.<id>.outcome` and `steps.<id>.conclusion` to the steps context.
+
+This allows downstream a step to run based on whether a previous step succeeded or failed.
+
+Reminder, currently the steps contains `steps.<id>.outputs`.
+
+## Decision
+
+For steps that have completed, populate `steps.<id>.outcome` and `steps.<id>.conclusion` with one of the following values:
+
+- `success`
+- `failure`
+- `cancelled`
+- `skipped`
+
+When a continue-on-error step fails, the outcome will be `failure` even though the final conclusion is `success`.
+
+### Example
+
+```yaml
+steps:
+
+  - id: experimental
+    continue-on-error: true
+    run: ./build.sh experimental
+
+  - if: ${{ steps.experimental.outcome == 'success' }}
+    run: ./publish.sh experimental
+```
+
+### Terminology
+
+The runs API uses the term `conclusion`.
+
+Therefore we use a different term `outcome` for the value prior to continue-on-error.
+
+The following is a snippet from the runs API response payload:
+
+```json
+      "steps": [
+        {
+          "name": "Set up job",
+          "status": "completed",
+          "conclusion": "success",
+          "number": 1,
+          "started_at": "2020-01-09T11:06:16.000-05:00",
+          "completed_at": "2020-01-09T11:06:18.000-05:00"
+        },
+```
+
+## Consequences
+
+- Update runner
+- Update [docs](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/contexts-and-expression-syntax-for-github-actions#steps-context)

+# ADR 0276: Problem Matchers
+
+**Date** 2019-06-05
+
+**Status** Accepted
+
+## Context
+
+Compilation failures during a CI build should surface good error messages.
+
+For example, the actual compile errors from the typescript compiler should bubble as issues in the UI. And not simply "tsc exited with exit code 1".
+
+VSCode has an extensible model for solving this type of problem. VSCode allows users to configure which problems matchers to use, when scanning output. For example, a user can apply the `tsc` problem matcher to receive a rich error output experience in VSCode, when compiling their typescript project.
+
+The problem-matcher concept fits well with "setup" actions. For example, the `setup-nodejs` action will download node.js, add it to the PATH, and register the `tsc` problem matcher. For the duration of the job, the `tsc` problem matcher will be applied against the output.
+
+## Decision
+
+### Registration
+
+#### Using `##` command
+
+`##[add-matcher]path-to-problem-matcher-config.json`
+
+Using a `##` command allows for flexibility:
+- Ad hoc scripts can register problem matchers
+- Allows problem matchers to be conditionally registered
+
+Note, if a matcher with the same name is registered a second time, it will clobber the first instance.
+
+#### Unregister using `##` command
+
+A way out for rare cases where scoping is a problem.
+
+`##[remove-matcher]owner`
+
+For this to be usable, the `owner` needs to be discoverable. Therefore, debug print the owner on registration.
+
+### Single line matcher
+
+Consider the output:
+
+```
+[...]
+
+Build FAILED.

+```
+
+The below match configuration uses a regular expression to discover problem lines. And the match groups are mapped into issue-properties.
+
+```json
+"owner": "msbuild",
+"pattern": [
+  {
+    "regexp": "^\\s*([^:]+)\\((\\d+),(\\d+)\\): (error|warning) ([^:]+): (.*) \\[(.+)\\]$",

+    "severity": 4,
+    "code": 5,
+    "message": 6,
+    "fromPath": 7
+  }
+]
+```
+
+The above output and match configuration produces the following matches:
+
+```
+line:     Class1.cs(16,24): warning CS0612: 'ClassLibrary1.Helpers.MyHelper.Name' is obsolete [C:\myrepo\myproject\ConsoleApp1\ClassLibrary1\ClassLibrary1.csproj]

+```
+
+Additionally the line will appear red in the web UI (prefix with `##[error]`).
+
+Note, an error does not imply task failure. Exit codes communicate failure.
+
+Note, strip color codes when evaluating regular expressions.
+
+### Multi-line matcher
+
+Consider the below output from ESLint in stylish mode. The file name is printed once, yet multiple error lines are printed.
+
+```

+```
+
+The below match configuration uses multiple regular expressions, for the multiple lines.
+
+And the last pattern of a multiline matcher can specify the `loop` property. This allows multiple errors to be discovered.
+
+```json

+"pattern": [
+  {
+    "regexp": "^([^\\s].*)$",
+    "file": 1
+  },

+    "severity": 3,
+    "message": 4,
+    "code": 5,
+    "loop": true
+  }
+]
+```
+
+The above output and match configuration produces two matches:
+
+```
+line:     1:0   error  Missing "use strict" statement                 strict
+file:     test.js
+line:     1

+
+```

+line:     5
+column:   10
+severity: error
+message:  'addOne' is defined but never used
+code:     no-unused-vars
+```
+
+Note, in the above example only the error line will appear red in the web UI. The \"file\" line will not appear red.
+
+### Other details
+
+#### Configuration `owner`
+
+Can be used to stomp over or remove.
+
+#### Rooting the file
+
+The goal of the file information is to provide a hyperlink in the UI.
+
+Solving this problem means:
+- Rooting the file when unrooted:
+  - Use the `fromPath` if specified (assume file path)
+  - Use the `github.workspace` (where the repo is cloned on disk)
+- Match against a repository to determine the relative path within the repo
+
+This is a place where we diverge from VSCode. VSCode task configurations are specific to the local workspace (workspace root is known or can be specified). We're solving a more generic problem, so we need more information - specifically the `fromPath` property - in order to accurately root the path.
+
+In order to avoid creating inaccurate hyperlinks on the error issues, the agent will verify the file exists and is in the main repository. Otherwise omit the file property from the error issue and debug trace what happened.
+
+#### Supported severity levels
+
+Ordinal ignore case:
+
+- `warning`
+- `error`
+
+Coalesce empty with \"error\". For any other values, omit logging an issue and debug trace what happened.
+
+#### Default severity level
+
+Problem matchers are unable to interpret severity strings other than `warning` and `error`. The `severity` match group expects `warning` or `error` (case insensitive).
+
+However some tools indicate error/warning in different ways. For example `flake8` uses codes like `E100`, `W200`, and `F300` (error, warning, fatal, respectively).
+
+Therefore, allow a property `severity`, sibling to `owner`, which identifies the default severity for the problem matcher. This allows two problem matchers to be registered - one for warnings and one for errors.
+
+For example, given the following `flake8` output:
+
+```
+./bootcamp/settings.py:156:80: E501 line too long (94 > 79 characters)
+./bootcamp/settings.py:165:5: F403 'from local_settings import *' used; unable to detect undefined names
+```
+
+Two problem matchers can be used:
+
+```json
+{
+    "problemMatcher": [
+        {
+            "owner": "flake8",
+            "pattern": [
+                {
+                    "regexp": "^(.+):(\\d+):(\\d+): ([EF]\\d+) (.+)$",
+                    "file": 1,
+                    "line": 2,
+                    "column": 3,
+                    "code": 4,
+                    "message": 5
+                }
+            ]
+        },
+        {
+            "owner": "flake8-warnings",
+            "severity": "warning",
+            "pattern": [
+                {
+                    "regexp": "^(.+):(\\d+):(\\d+): (W\\d+) (.+)$",
+                    "file": 1,
+                    "line": 2,
+                    "column": 3,
+                    "code": 4,
+                    "message": 5
+                }
+            ]
+        }
+    ]
+}
+```
+
+#### Mitigate regular expression denial of service (ReDos)
+
+If a matcher exceeds a 1 second timeout when processing a line, retry up to two three times total.
+After three unsuccessful attempts, warn and eject the matcher. The matcher will not run again for the duration of the job.
+
+### Where we diverge from VSCode
+
+- We added the `fromPath` concept for rooting paths. This is done differently in VSCode, since a task is the scope (root path well known). For us, the job is the scope.
+- VSCode allows additional activation info background tasks that are always running (recompile on files changed). They allow regular expressions to define when the matcher scope begins and ends. This is an interesting concept that we could leverage to help solve our scoping problem.
+
+## Consequences
+
+- Setup actions should register problem matchers

+# ADR 0277: Run action shell option
+
+**Date** 2019-07-09
+
+**Status** Accepted
+
+## Context
+run-actions run scripts using a platform specific shell:
+`bash -eo pipefail` on non-windows, and `cmd.exe /c /d /s` on windows
+
+The `shell` option overwrites this to allow different flags or completely different shells/interpreters
+
+A small example is:
+```yml
+jobs:
+  bash-job:
+    actions:
+    - run: echo "Hello"
+      shell: bash
+  python-job:
+    actions:
+    - run: print("Hello")
+      shell: python {0}
+```
+
+## Decision
+
+___
+
+### Shell option
+The keyword being used is `shell` 
+
+`shell` can be either:
+
+1. Builtins / Explicitly supported keywords. It is useful to support at least `cmd`, and `powershell` on Windows. Because `cmd my_cmd_script` and `powershell my_ps1_script` are not valid the same way many Linux/cross-platform interpreters are, e.g. `bash myscript` or `python myscript`. Those tools (and potentially others) also require the correct file extension to run, or must be run in a particular way to get the exit codes consistently, so we must have first class knowledge about them. We provide default templates for these keywords as follows:
+    - `cmd`: Default is: `%ComSpec% /D /E:ON /V:OFF /S /C "CALL "{0}""` where the script name is automatically appended with `.cmd` and substituted for `{0}`
+        - Note this is equivalent to the default Windows behavior if no shell option is given
+    - `pwsh`: Default is: `pwsh -command "& '{0}'"` where the script is automatically appended with `.ps1`
+    - `powershell`: Default is: `powershell -command "& '{0}'"` where the script is automatically appended with `.ps1`
+    - `bash`: Uses `bash --noprofile --norc -eo pipefail {0}`
+        - The default behavior on non-Windows if no shell is given is to attempt this first
+    - `sh`: Uses `sh -e {0}`
+        - This is the default behavior on non-Windows if no shell is given, AND `bash` (see above) was not located on the PATH
+    - `python`: `python {0}`
+    - **NOTE**: The exact command ran may vary by machine. We only provide default arguments and command format for the listed shell. While the above behavior is expected on hosted machines, private runners may vary. For example, `sh` (or other commands) may actually be a link to `/bin/dash`, `/bin/bash`, or other
+
+1. A template string: `command [...options] {0} [...more_options]`
+    - As above, the file name of the temporary script will be templated in. This gives users more control to have options at any location relative to the script path
+    - The first whitespace-delimited word of the string will be interpreted as the command
+    - e.g. `python {0} arg1 arg2` or similar can be used if passing args is needed. Some shells will require other options after the filename for various reasons
+
+Note that (1) simply provides defaults that are executed with the same mechanism as (2). That is:
+- A temporary script file is generated, and the path to that file is templated into the string at `{0}`
+- The first word of the formatted string is assumed to be a command, and we attempt to locate its full path
+- The fully qualified path to the command, plus the remaining arguments, is executed
+    - e.g. `shell: bash` expands to `/bin/bash --noprofile --norc -eo pipefail /runner/_layout/_work/_temp/f8d4fb2b-19d9-47e6-a786-4cc538d52761.sh` on my private runner
+
+At this time, **THE LIST OF WELL-KNOWN SHELL OPTIONS IS**:
+- cmd - Windows (hosted vs2017, vs2019) only
+- powershell - Windows (hosted vs2017, vs2019) only
+- sh - All hosted platforms
+- pwsh - All hosted platforms
+- bash - All hosted platforms
+- python - All hosted platforms. Can use setup-python to configure which python will be used
+___
+
+### Containers
+For container jobs, `shell` should just work the same as above, transparently. We will simply `exec` the command in the job container, passing the same arguments in
+
+___
+
+### Exit codes / Error action preference
+
+For builtin shells, we provide defaults that make the most sense for CI, running within Actions, and being executed by our runner
+
+bash/sh:
+- Fail-fast behavior using `set -e o pipefail` is the default for `bash` and `shell` builtins, and by default when no option is given on non-Windows platforms
+- Users can opt out of fail-fast and take full control easily by providing a template string to the shell options, eg: `bash {0}`.
+- sh-like shells exit with the exit code of the last command executed in a script, and is our default behavior. Thus the runner reports the status of the step as fail/succeed based on this exit code
+
+powershell/pwsh
+- Fail-fast behavior when possible. For `pwsh` and `powershell` builtins, we will prepend `$ErrorActionPreference = 'stop'` to script contents
+- We append `if ((Test-Path -LiteralPath variable:\LASTEXITCODE)) { exit $LASTEXITCODE }` to powershell scripts to get Action statuses to reflect the script's last exit code
+- Users can always opt out by not using the builtins, and providing a shell option like: `pwsh -File {0}`, or `powershell -Command "& '{0}'"`, depending on need
+
+cmd
+- There doesn't seem to be a way to fully opt in to fail-fast behavior other than writing your script to check each error code and respond accordingly, so we can't actually provide that behavior by default, it will be completely up to the user to write this behavior into their script
+- cmd.exe will exit (return the error code to the runner) with the errorlevel of the last program it executed. This is internally consistent with the previous default behavior (sh, pwsh) and is the cmd.exe default, so we keep that behavior
+
+## Consequences
+Valid `shell` options will depend on the hosted images. We will need to maintain tight image compat
+
+First class support for a shell will require a major version schema change to modify. We cannot remove or modify the behavior of a well-known supported option, However, adding first class support for new shells is backwards compatible. For instance, we can add a well-known `python` option, because non-well-known options would have always needed to include `{0}`, e.g. `python {0}`

+**Date**: 2019-09-30
+
+**Status**: Accepted
+
+## Context
+
+User wants to reference workflow variables defined in workflow yaml file for action's input, displayName and condition.  
+
+## Decision
+
+### Add `env` context in the runner
+
+Runner will create and populate the `env` context for every job execution using following logic:
+1. On job start, create `env` context with any environment variables in the job message, these are env defined in customer's YAML file's job/workflow level `env` section.
+2. Update `env` context when customer use `::set-env::` to set env at the runner level.
+3. Update `env` context with step's `env` block before each step runs.
+
+The `env` context is only available in the runner, customer can't use the `env` context in any server evaluation part, just like the `runner` context
+
+Example yaml:
+```yaml
+
+env:
+  env1: 10
+  env2: 20
+  env3: 30
+jobs:
+  build:
+    env:
+      env1: 100
+      env2: 200
+    runs-on: ubuntu-latest
+    steps:
+      - run: |
+          echo ${{ env.env1 }}  // 1000
+          echo $env1            // 1000
+          echo $env2            // 200
+          echo $env3            // 30
+        if: env.env2 == 200     // true
+        name: ${{ env.env1 }}_${{ env.env2 }}   //1000_200
+        env:
+          env1: 1000
+```
+
+### Don't populate the `env` context with environment variables from runner machine. 
+
+With job container and container action, the `env` context may not have the right value customer want and will cause confusion.  
+Ex:
+```yaml
+build:
+  runs-on: ubuntu-latest   <- $USER=runner in hosted machine
+  container: ubuntu:16.04   <- $USER=root in container
+  steps:
+  - run: echo ${{env.USER}}    <- what should customer expect this output?  runner/root
+  - uses: docker://ubuntu:18.04
+    with:
+      args: echo ${{env.USER}}  <- what should customer expect this output? runner/root

+# ADR 0279: HashFiles Expression Function
+
+**Date**: 2019-09-30
+
+**Status**: Accepted
+
+## Context
+First party action `actions/cache` needs a input which is an explicit `key` used for restoring and saving the cache. For packages caching, the most comment `key` might be the hash result of contents from all `package-lock.json` under `node_modules` folder.
+  
+There are serval different ways to get the hash `key` input for `actions/cache` action.
+
+1. Customer calculate the `key` themselves from a different action, customer won't like this since it needs extra step for using cache feature
+```yaml
+  steps:
+  - run: |
+      hash=some_linux_hash_method(file1, file2, file3)
+      echo ::set-output name=hash::$hash
+    id: createHash
+  - uses: actions/cache@v1
+    with:
+      key: ${{ steps.createHash.outputs.hash }}
+``` 
+
+2. Make the `key` input of `actions/cache` follow certain convention to calculate hash, this limited the `key` input to a certain format customer may not want.
+```yaml
+  steps:
+  - uses: actions/cache@v1
+    with:
+      key: ${{ runner.os }}|${{ github.workspace }}|**/package-lock.json
+```
+
+## Decision
+
+### Add hashFiles() function to expression engine for calculate files' hash
+
+`hashFiles()` will only allow on runner side since it needs to read files on disk, using `hashFiles()` on any server side evaluated expression will cause runtime errors.
+
+`hashFiles()` will only support hashing files under the `$GITHUB_WORKSPACE` since the expression evaluated on the runner, if customer use job container or container action, the runner won't have access to file system inside the container.
+
+`hashFiles()` will only take 1 parameters:
+ - `hashFiles('**/package-lock.json')`  // Search files under $GITHUB_WORKSPACE and calculate a hash for them
+
+**Question: Do we need to support more than one match patterns?**  
+Ex: `hashFiles('**/package-lock.json', '!toolkit/core/package-lock.json', '!toolkit/io/package-lock.json')`  
+Answer: Only support single match pattern for GA, we can always add later.
+
+This will help customer has better experience with the `actions/cache` action's input.
+```yaml
+  steps:
+  - uses: actions/cache@v1
+    with:
+      key: ${{hashFiles('**/package-lock.json')}}-${{github.ref}}-${{runner.os}}
+```
+
+For search pattern, we will use basic globbing (`*` `?` and `[]`) and globstar (`**`).
+
+Additional pattern details:
+- Root relative paths with `github.workspace` (the main repo)
+- Make `*` match files that start with `.`
+- Case insensitive on Windows
+- Accept `\` or `/` path separators on Windows
+
+Hashing logic:
+1. Get all files under `$GITHUB_WORKSPACE`.
+2. Use search pattern filter all files to get files that matches the search pattern. (search pattern only apply to file path not folder path)
+3. Sort all matched files by full file path in alphabet order.
+4. Use SHA256 algorithm to hash each matched file and store hash result.
+5. Use SHA256 to hash all stored files' hash results to get the final 64 chars hash result.
+
+**Question: Should we include the folder structure info into the hash?**  
+Answer: No

+# ADR 0280: Echoing of Command Input
+
+**Date**: 2019-11-04  
+
+**Status**: Accepted
+
+## Context
+
+Command echoing as a default behavior tends to clutter the user logs, so we want to swap to a system where users have to opt in to see this information.
+
+Command outputs will still be echoed in the case there are any errors processing such commands. This is so the end user can have more context on why the command failed and help with troubleshooting.
+
+Echo output in the user logs can be explicitly controlled by the new commands `::echo::on` and `::echo::off`. By default, echoing is enabled if `ACTIONS_STEP_DEBUG` secret is enabled, otherwise echoing is disabled.
+
+## Decision
+- The only commands that currently echo output are
+  - `remove-matcher`
+  - `add-matcher`
+  - `add-path`
+- These will no longer echo the command, if processed successfully
+- All commands echo the input when any of these conditions is fulfilled:
+  1. When such commands fail with an error
+  2. When `::echo::on` is set
+  3. When the `ACTIONS_STEP_DEBUG` is set, and echoing hasn't been explicitly disabled with `::echo::off`
+- There are a few commands that won't be echoed, even when echo is enabled. These are (as of 2019/11/04):
+   - `add-mask`
+   - `debug`
+   - `warning`
+   - `error`
+- The three commands above will not echo, either because echoing the command would leak secrets (e.g. `add-mask`), or it would not add any additional troubleshooting information to the logs (e.g. `debug`). It's expected that future commands would follow these "echo-suppressing" guidelines as well. Echo-suppressed commands are still free to output other information to the logs, as deemed fit.

+# ADR 0297: Base64 Masking Trailing Characters
+
+**Date** 2020-01-21
+
+**Status** Proposed
+
+## Context
+
+The Runner registers a number of Value Encoders, which mask various encodings of a provided secret. Currently, we register a 3 base64 Encoders:
+- The base64 encoded secret
+- The secret with the first character removed then base64 encoded
+- The secret with the first two characters removed then base64 encoded
+
+This gives us good coverage across the board for secrets and secrets with a prefix (i.e. `base64($user:$pass)`).
+
+However, we don't have great coverage for cases where the secret has a string appended to it before it is base64 encoded (i.e.: `base64($pass\n))`). 
+
+Most notably we've seen this as a result of user error where a user accidentially appends a newline or space character before encoding their secret in base64.
+
+## Decision
+
+### Trim end characters
+
+We are going to modify all existing base64 encoders to trim information before registering as a secret.
+We will trim:
+- `=` from the end of all base64 strings. This is a padding character that contains no information. 
+  - Based on the number of `=`'s at the end of a base64 string, a malicious user could predict the length of the original secret modulo 3. 
+    - If a user saw `***==`, they would know the secret could be 1,4,7,10... characters.
+- If a string contains `=` we will also trim the last non-padding character from the base64 secret.
+  - This character can change if a string is appended to the secret before the encoding.
+
+
+### Register a fourth encoder
+
+We will also add back in the original base64 encoded secret encoder for four total encoders:
+- The base64 encoded secret
+- The base64 encoded secret trimmed
+- The secret with the first character removed then base64 encoded and trimmed
+- The secret with the first two characters removed then base64 encoded and trimmed
+
+This allows us to fully cover the most common scenario where a user base64 encodes their secret and expects the entire thing to be masked.
+This will result in us only revealing length or bit information when a prefix or suffix is added to a secret before encoding. 
+
+## Consequences
+
+- In the case where a secret has a prefix or suffix added before base64 encoding, we may now reveal up to 20 bits of information and the length of the original string modulo 3, rather then the original 16 bits and no length information
+- Secrets with a suffix appended before encoding will now be masked across the board. Previously it was only masked if it was a multiple of 3 characters
+- Performance will suffer in a neglible way

+
+## Context
+
+- Provide a mechanism in the runner to include extra information in `Set up job` step's log.
+  Ex: Include OS/Software info from Hosted image.
+
+## Decision
+
+The runner will look for a file `.setup_info` under the runner's root directory, The file can be a JSON with a simple schema.
+```json
+[
+  {
+    "group": "OS Detail",
+    "detail": "........"
+  },

+```
+The runner will use `##[group]` and `##[endgroup]` to fold all detail info into an expandable group.
+
+Both [virtual-environments](https://github.com/actions/virtual-environments) and self-hosted runners can use this mechanism to add extra logging info to the `Set up job` step's log.
+
+## Consequences
+
+1. Change the runner to best effort read/parse `.extra_setup_info` file under runner root directory.
+2. [virtual-environments](https://github.com/actions/virtual-environments) generate the file during image generation.
+3. Change MMS provisioner to properly copy the file to runner root directory at runtime.

+# 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).
+
+### 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 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).
+
+### 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 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
+
+**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 runing
+    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** 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
+      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 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
+      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 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.

+# Runner Authentication and Authorization
+
+## Goals
+  - Support runner installs in untrusted domains.
+  - The account that configures or runs the runner process is not relevant for accessing GitHub resources.
+  - Accessing GitHub resources is done with a per-job token which expires when job completes.
+  - The token is granted to trusted parts of the system including the runner, actions and script steps specified by the workflow author as trusted.
+  - All OAuth tokens that come from the Token Service that the runner uses to access Actions Service resources are the same. It's just the scope and expiration of the token that may vary.
+
+## Configuration
+
+Configuring a self-hosted runner is [covered here in the documentation](https://help.github.com/en/actions/hosting-your-own-runners/adding-self-hosted-runners).
+
+Configuration is done with the user being authenticated via a time-limited, GitHub runner registration token.
+
+*Your credentials are never used for registering the runner with the service.*
+
+![Self-hosted runner config](../res/self-hosted-config.png)
+
+During configuration, an RSA public/private key pair is created, the private key is stored in file on disk. On Windows, the content is protected with DPAPI (machine level encrypted - runner only valid on that machine) and on Linux/OSX with `chmod` permissions.
+
+Using your credentials, the runner is registered with the service by sending the public key to the service which adds that runner to the pool and stores the public key, the Token Service will generate a `clientId` associated with the public key.
+
+## Start and Listen
+
+After configuring the runner, the runner can be started interactively (`./run.cmd` or `./run.sh`) or as a service.
+
+![Self-hosted runner start](../res/self-hosted-start.png)
+
+On start, the runner listener process loads the RSA private key (on Windows decrypting with machine key DPAPI), and asks the Token Service for an OAuth token which is signed with the RSA private key.
+The server then responds with an OAuth token that grants permission to access the message queue (HTTP long poll), allowing the runner to acquire the messages it will eventually run.
+
+## Run a workflow
+
+When a workflow is run, its labels are evaluated, it is matched to a runner and a message is placed in a queue of messages for that runner.  
+The runner then starts listening for jobs via the message queue HTTP long poll.  
+The message is encrypted with the runner's public key, stored during runner configuration.  
+
+![Runner workflow run](../res/workflow-run.png)
+
+A workflow is queued as a result of a triggered [event](https://help.github.com/en/actions/reference/events-that-trigger-workflows). Workflows can be scheduled to [run at specific UTC times](https://help.github.com/en/actions/reference/events-that-trigger-workflows#scheduled-events-schedule) using POSIX `cron` syntax.
+An [OAuth token](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html) is generated, granting limited access to the host in Actions Service associated with the github.com repository/organization.
+The lifetime of the OAuth token is the lifetime of the run or at most the [job timeout (default: 6 hours)](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idtimeout-minutes), plus 10 additional minutes.
+
+## Accessing GitHub resources
+
+The job message sent to the runner contains the OAuth token to talk back to the Actions Service.
+The runner listener parent process will spawn a runner worker process for that job and send it the job message over IPC.
+The token is never persisted.
+
+Each action is run as a unique subprocess.
+The encrypted access token will be provided as an environment variable in each action subprocess.  
+The token is registered with the runner as a secret and scrubbed from the logs as they are written.
+
+Authentication in a workflow run to github.com can be accomplished by using the [`GITHUB_TOKEN`](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token#about-the-github_token-secret)) secret. This token expires after 60 minutes. Please note that this token is different from the OAuth token that the runner uses to talk to the Actions Service.
+
+## Hosted runner authentication
+
+Hosted runner authentication differs from self-hosted authentication in that runners do not undergo a registration process, but instead, the hosted runners get the OAuth token directly by reading the `.credentials` file. The scope of this particular token is limited for a given workflow job execution, and the token is revoked as soon as the job is finished.
