Overview

BGraph

BGraph is a tool designed to generate dependencies graphs from Android.bp soong files.

Overview

BGraph (for Build-Graphs) is a project aimed at create build graphs from blueprints in AOSP and querying those graphs.

In short, this project builds/uses Unified Dependency Graph for the Android Open Source Project by parsing and linking modules defined in the Android build system Soong.

Use-cases

You should use this tool if you want to find:

all the dependencies of a source file in AOSP;
all the sources involved in the building of a target in AOSP;
common dependencies between two targets.

Usage

% bgraph --help                                                       
Usage: bgraph [OPTIONS] COMMAND [ARGS]...

  BGraph - generate and query build dependency graphes.

  BGraph is used to manipulate build dependency graphs generated from
  blueprint files. The main commands are:

      - generate : used to generates multiples graphs

      - query: used to query a previously generated graph

  To get more help, see the online documentation.

Options:
  -v, --verbose         Activate verbose output  [default: False]
  --install-completion  Install completion for the current shell.
  --show-completion     Show completion for the current shell, to copy it or
                        customize the installation.

  --help                Show this message and exit.

Commands:
  generate         Generate BGraph's from a mirror dir.
  generate-single  Generate a BGraph from a branch.
  list             List the BGraph already generated.
  query            Query a BGraph.

Installation

Using poetry

poetry install bgraph

Using pip

pip install bgraph

Using docker

docker build -f docker/Dockerfile -t bgraph .

This will create a container with git, repo and bgraph and will take some time (because it compiles git from the source).

See Docker for more instructions.

Prerequisites

python3.8

Optional dependencies for the builder:

repo
git (>25): since we're using partial-checkouts, a modern version of git is required
at least 1Go of free disk space
(Optional: AOSP mirror)

See Building from AOSP for more details.
