bp2build progress graphs

This directory contains tools to generate reports and .png graphs of the bp2build conversion progress, for any module.

This tool relies on json-module-graph and bp2build to be buildable targets for this branch.

Prerequisites

  • /usr/bin/dot: turning dot graphviz files into .pngs

Tip: --use_queryview=true runs bp2build_progress.py with queryview.

Instructions

Generate the report for a module, e.g. adbd

b run //build/bazel/scripts/bp2build_progress:bp2build_progress \
  -- report -m <module-name>

or:

b run //build/bazel/scripts/bp2build_progress:bp2build_progress \
  -- report -m <module-name> --use-queryview

When running in report mode, you can also write results to a proto with the flag --proto-file

Generate the report for a module, e.g. adbd

b run //build/bazel/scripts/bp2build_progress:bp2build_progress \
  -- graph -m adbd > /tmp/graph.in && \
  dot -Tpng -o /tmp/graph.png /tmp/graph.in

or:

b run //build/bazel/scripts/bp2build_progress:bp2build_progress \
  -- graph -m adbd --use-queryview > /tmp/graph.in && \
  dot -Tpng -o /tmp/graph.png /tmp/graph.in
