# Mergify CI Commands

## Overview

The `mergify ci` command group provides tools for CI pipelines: uploading JUnit test results to Mergify CI Insights, detecting git references for diff-based operations, managing CI scopes for selective testing, and retrieving merge queue batch metadata.

## Commands

```bash
mergify ci junit-process FILES...         # Upload JUnit XML + evaluate quarantine (primary command)
mergify ci junit-upload FILES...          # (Deprecated) Use junit-process instead
mergify ci git-refs                       # Detect base/head git references for the current PR
mergify ci scopes --config PATH           # Detect scopes impacted by changed files
mergify ci scopes-send -s SCOPE           # Send scopes tied to a pull request to Mergify
mergify ci queue-info                     # Output merge queue batch metadata from the current PR event
```

## JUnit Processing (`junit-process`)

The primary CI command. Parses JUnit XML reports, checks quarantine status for failing tests, uploads results to Mergify CI Insights, and determines the final CI exit code.

```bash
mergify ci junit-process \
  --token "$MERGIFY_TOKEN" \
  --repository owner/repo \
  --tests-target-branch main \
  path/to/junit-results.xml
```

`FILES` can be individual paths or quoted glob patterns (e.g. `'reports/**/*.xml'`). Always quote the pattern so Mergify expands it rather than the shell — this is the recommended approach for large, sharded test suites.

**Key options:**
- `--token` / `-t` (env: `MERGIFY_TOKEN`) -- CI Insights application key
- `--repository` / `-r` -- Repository full name (auto-detected in GitHub Actions)
- `--tests-target-branch` / `-ttb` -- Branch used for quarantine evaluation. Auto-detected per CI provider: GitHub Actions (`GITHUB_BASE_REF` → `GITHUB_HEAD_REF` → `GITHUB_REF_NAME` → `GITHUB_REF`), Buildkite (`BUILDKITE_PULL_REQUEST_BASE_BRANCH` → `BUILDKITE_BRANCH`), CircleCI (`CIRCLE_BRANCH`), Jenkins (`CHANGE_TARGET` → `GIT_BRANCH`).
- `--api-url` / `-u` (env: `MERGIFY_API_URL`) -- Mergify API URL (default: `https://api.mergify.com`)
- `--test-framework` -- Test framework name (optional metadata)
- `--test-language` -- Test language (optional metadata)
- `--test-exit-code` / `-e` (env: `MERGIFY_TEST_EXIT_CODE`) -- Exit code of the test runner, used to detect silent failures where the runner crashed but the JUnit report appears clean

**Behavior:**
1. Parses JUnit XML files into test spans
2. Checks quarantine status for failing tests against the Mergify API
3. Uploads all test spans to Mergify CI Insights
4. Prints a summary: tests run, failures, quarantined vs blocking
5. Exits with code 0 if all failures are quarantined, code 1 if any are blocking
6. If `--test-exit-code` is non-zero but no test failures are found, exits with code 1 (silent failure detection)

**GitHub Actions example:**
```yaml
- name: Run tests
  id: tests
  run: pytest --junitxml=results.xml || echo "exit_code=$?" >> "$GITHUB_OUTPUT"

- name: Process test results
  if: always()
  run: |
    mergify ci junit-process \
      --test-exit-code ${{ steps.tests.outputs.exit_code || 0 }} \
      results.xml
  env:
    MERGIFY_TOKEN: ${{ secrets.MERGIFY_TOKEN }}
```

## Git References (`git-refs`)

Detects the base and head git references for the current pull request context. Writes results to `GITHUB_OUTPUT` when running in GitHub Actions, and to Buildkite meta-data (`mergify-ci.base`, `mergify-ci.head`, `mergify-ci.source`) when running in Buildkite.

```bash
mergify ci git-refs
# Output:
# Base: abc1234
# Head: def5678
```

**Output formats (`--format`):**
- `text` (default) — human-readable `Base:` / `Head:` lines
- `shell` — `MERGIFY_GIT_REFS_{BASE,HEAD,SOURCE}=...` lines suitable for `eval`, with POSIX-safe shell quoting. When base can't be detected, `MERGIFY_GIT_REFS_BASE=''`.
- `json` — single-line JSON object with `base`, `head`, `source` keys. `base` may be `null` when it can't be detected (e.g., `workflow_dispatch` events); use `jq -r '.base // ""'` to coalesce to empty string.

```bash
# Consume values in a shell script without parsing:
eval "$(mergify ci git-refs --format=shell)"
nx show projects --affected \
  --base="$MERGIFY_GIT_REFS_BASE" \
  --head="$MERGIFY_GIT_REFS_HEAD"

# Or with jq:
BASE=$(mergify ci git-refs --format=json | jq -r '.base // ""')
```

Sources detected (in priority order): merge queue context, GitHub pull request event, GitHub push event, fallback to last commit.

## Scopes (`scopes`)

Detects which CI scopes are impacted by changed files, based on a Mergify configuration file. Used for selective/targeted CI -- only run tests for scopes that have changed files.

```bash
# Detect scopes from changed files
mergify ci scopes --config .mergify.yml

# Detect scopes with explicit base/head
mergify ci scopes --config .mergify.yml --base origin/main --head HEAD

# Write detected scopes to a file
mergify ci scopes --config .mergify.yml --write scopes.json
```

**Key options:**
- `--config` (env: `MERGIFY_CONFIG_PATH`) -- Path to the Mergify YAML config file (auto-detected)
- `--base` -- Base git reference (auto-detected)
- `--head` -- Head git reference (default: HEAD)
- `--write` / `-w` -- Write detected scopes to a JSON file

The config file defines scopes with file patterns. When files change between base and head, matching scopes are identified and written to `GITHUB_OUTPUT` (on GitHub Actions) or to Buildkite meta-data under `mergify-ci.scopes` (on Buildkite), as a JSON map of scope names to `"true"`/`"false"`.

## Scopes Send (`scopes-send`)

Sends scopes tied to a pull request to the Mergify API. Used when scopes are determined manually or from a file rather than auto-detected.

```bash
# Send specific scopes
mergify ci scopes-send -s frontend -s backend -p 123

# Send scopes from a JSON file (produced by `mergify ci scopes --write`)
mergify ci scopes-send --scopes-json scopes.json -p 123

# Send scopes from a plain-text file (one scope per line)
mergify ci scopes-send --scopes-file scopes.txt -p 123
```

**Key options:**
- `--token` / `-t` (env: `MERGIFY_TOKEN`) -- Mergify key
- `--repository` / `-r` -- Repository full name (auto-detected)
- `--pull-request` / `-p` -- Pull request number (auto-detected in GitHub Actions)
- `--scope` / `-s` -- Scope name (repeatable)
- `--scopes-json` -- JSON file containing scopes (output of `mergify ci scopes --write`)
- `--scopes-file` -- Plain-text file with one scope per line

## Queue Info (`queue-info`)

Outputs merge queue batch metadata from the current pull request event. Only works on merge queue draft pull requests. Writes output to `GITHUB_OUTPUT` when running in GitHub Actions.

```bash
mergify ci queue-info
# Output: JSON with batch metadata
```

This command is useful in CI workflows that need to know whether the current run is part of a merge queue batch and what other PRs are in the batch.

## Common Patterns

### Full CI pipeline with quarantine
```yaml
jobs:
  test:
    steps:
      - uses: actions/checkout@v4
      - name: Run tests
        run: pytest --junitxml=results.xml
      - name: Upload and evaluate
        if: always()
        run: mergify ci junit-process results.xml
        env:
          MERGIFY_TOKEN: ${{ secrets.MERGIFY_TOKEN }}
```

### Selective testing with scopes
```yaml
jobs:
  detect:
    outputs:
      scopes: ${{ steps.scopes.outputs.scopes }}
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - id: scopes
        run: mergify ci scopes --config .mergify.yml

  backend:
    needs: detect
    if: fromJSON(needs.detect.outputs.scopes).backend == 'true'
    steps:
      - run: pytest backend/
```
