## 项目历史与用法

bazel-diff is Tinder's command-line utility for computing the Bazel targets affected between two Git revisions, letting CI systems build or test the precise changed target set instead of rerunning an entire monorepo.

### 项目历史

The upstream repository begins in September 2020 with a v1.0-era implementation of Bazel target diffing. Its README frames the project as an answer to a gap in Bazel itself, pointing to the long-running Bazel feature request for native target diffing and to a BazelCon talk as design inspiration.

The tool's implementation history is tied to very large Bazel graphs: the README calls out streamed protobuf query output, avoidance of long command-line query lists, support for renamed/deleted/modified files, and testing against projects with tens of thousands of targets.

### 采用历史

Adoption is strongest among Bazel monorepo users who need deterministic affected-target selection for pull-request CI. The Homebrew formula packages it as a standalone CLI, making it accessible outside the original Tinder repository.

Later README additions describe an experimental HTTP query service and cached hash generation, showing a shift from one-shot local comparison toward always-on CI infrastructure for large repositories.

### 使用方式

A typical workflow checks out a base revision, generates Bazel graph hashes, checks out a final revision, generates hashes again, and runs get-impacted-targets to emit the changed target labels as JSON.

The tool is used when correctness matters more than approximate file globs: its docs explicitly warn that incorrect affected-test selection erodes trust in green-to-red CI transitions.

### 为什么软件包爱好者会关心

For package-history nerds, bazel-diff is a good example of the post-Bazel ecosystem filling operational gaps around monorepo CI rather than replacing Bazel itself.

It also illustrates why Bazel-adjacent packages often matter more as automation primitives than as developer-facing build tools: the interesting artifact is the affected-target JSON consumed by CI.

### 时间线

- 2020-09: Upstream git history starts with the initial v1.0-era bazel-diff code.
- 2020s: Homebrew packages bazel-diff as a standalone CLI for macOS and Linux users.
- 2020s: README-documented features expand to build graph distance metrics and an experimental long-running query service.

### Related projects

- Bazel supplies the query and build graph model that bazel-diff analyzes.
- Aspect's impacted command is documented by bazel-diff as a Starlark/Aspect CLI way to expose a similar impacted-target workflow.
- Bazelisk is commonly paired with bazel-diff in CI so the Bazel binary used for graph hashing matches the workspace's pinned version.
