 - 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

 We will update the Runner to use the conventional environment variables for proxies: `http_proxy`, `https_proxy` and `no_proxy` if they are set.

+# 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 the 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.

+
+    1 Warning(s)
+    1 Error(s)
+```
+
+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) ([^:]+): (.*) \\[(.+)\\]$",
+    "file": 1,
+    "line": 2,
+    "column": 3,
+    "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]
+file:     Class1.cs
+line:     16
+column:   24
+severity: warning
+code:     CS0612
+message:  'ClassLibrary1.Helpers.MyHelper.Name' is obsolete
+fromPath: C:\myrepo\myproject\ConsoleApp1\ClassLibrary1\ClassLibrary1.csproj
+```
+
+```
+line:     Helpers\MyHelper.cs(16,30): error CS1002: ; expected [C:\myrepo\myproject\ConsoleApp1\ClassLibrary1\ClassLibrary1.csproj]

+severity: error
+code:     CS1002
+message:  ; expected
+fromPath: 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.
+
+```
+test.js
+  1:0   error  Missing "use strict" statement                 strict
+  5:10  error  'addOne' is defined but never used             no-unused-vars
+✖ 2 problems (2 errors, 0 warnings)
+```
+
+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
+"owner": "eslint-stylish",
+"pattern": [
+  {
+    "regexp": "^([^\\s].*)$",
+    "file": 1
+  },
+  {
+    "regexp": "^\\s+(\\d+):(\\d+)\\s+(error|warning|info)\\s+(.*)\\s\\s+(.*)$",
+    "line": 1,
+    "column": 2,
+    "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
+column:   0
+severity: error
+message:  Missing "use strict" statement
+code:     strict
+```
+
+```
+line:     5:10  error  'addOne' is defined but never used             no-unused-vars
+file:     test.js
+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 configuration 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 are 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 doesnt 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 cant 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}`

+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.
+
+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: 100
+jobs:
+  build:
+    env:
+      env2: 200
+    runs-on: ubuntu-latest

+        name: ${{ env.env1 }}_${{ env.env2 }}
+```
+
+### 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:

+# 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

+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.
