# AdGuard Home scripts
## `hooks/`: Git hooks
### Usage
Run `make init` from the project root.
## `querylog/`: Query Log Helpers
### Usage
- `npm install`: install dependencies. Run this first.
- `npm run anonymize <source> <dst>`: read the query log from the `<source>` and write anonymized version to `<dst>`.
## `make/`: Makefile scripts
The release channels are: `development` (the default), `edge`, `beta`, and `release`. If verbosity levels aren’t documented here, there are only two: `0`, don’t print anything, and `1`, be verbose.
### `build-docker.sh`: Build a multi-architecture Docker image
Required environment:
- `CHANNEL`: release channel, see above.
- `DIST_DIR`: the directory where a release has previously been built.
- `REVISION`: current Git revision.
- `VERSION`: release version.
Optional environment:
- `DOCKER_IMAGE_NAME`: the name of the resulting Docker container. By default it’s `adguardhome-dev`.
- `DOCKER_OUTPUT`: the `--output` parameters. By default they are `type=image,name=${DOCKER_IMAGE_NAME},push=false`.
- `SUDO`: allow users to use `sudo` or `doas` with `docker`. By default none is used.
### `build-release.sh`: Build a release for all platforms
Required environment:
- `CHANNEL`: release channel, see above.
- `GPG_KEY` and `GPG_KEY_PASSPHRASE`: data for `gpg`. Only required if `SIGN` is `1`.
Optional environment:
- `ARCH` and `OS`: space-separated list of architectures and operating systems for which to build a release. For example, to build only for 64-bit ARM and AMD on Linux and Darwin:
```sh
make ARCH='amd64 arm64' OS='darwin linux' … build-release
```
The default value is `''`, which means build everything.
- `DIST_DIR`: the directory to build a release into. The default value is `dist`.
- `GO`: set an alternative name for the Go compiler.
- `SIGN`: `0` to not sign the resulting packages, `1` to sign. The default value is `1`.
- `VERBOSE`: `1` to be verbose, `2` to also print environment. This script calls `go-build.sh` with the verbosity level one level lower, so to get verbosity level `2` in `go-build.sh`, set this to `3` when calling `build-release.sh`.
- `VERSION`: release version. Will be set by `version.sh` if it is unset or if it has the default `Makefile` value of `v0.0.0`.
We’re using Go’s [forward compatibility mechanism][go-toolchain] for updating the Go version. This means that if your `go` version is 1.21+ but is different from the one required by AdGuard Home, the `go` tool will automatically download the required version.
If you want to use the version installed on your builder, run:
```sh
go get go@$YOUR_VERSION
go mod tidy
```
and call `make` with `GOTOOLCHAIN=local`.

### `go-bench.sh`: Run backend benchmarks
Optional environment:
- `GO`: set an alternative name for the Go compiler.
- `TIMEOUT_FLAGS`: set timeout flags for tests. The default value is `--timeout=30s`.

### `go-build.sh`: Build the backend
Optional environment:
- `GOAMD64`: architectural level for [AMD64][amd64]. The default value is `v1`.

- `GO`: set an alternative name for the Go compiler.
- `OUT`: output binary name.
- `PARALLELISM`: set the maximum number of concurrently run build commands (that is, compiler, linker, etc.).
- `SOURCE_DATE_EPOCH`: the [standardized][repr] environment variable for the Unix epoch time of the latest commit in the repository. If set, overrides the default obtained from Git. Useful for reproducible builds.
- `VERBOSE`: verbosity level. `1` shows every command that is run and every Go package that is processed. `2` also shows subcommands and environment. The default value is `0`, don’t be verbose.
- `VERSION`: release version. Will be set by `version.sh` if it is unset or if it has the default `Makefile` value of `v0.0.0`.
Required environment:
- `CHANNEL`: release channel, see above.
