Description

ratt (“Rebuild All The Things!”) operates on a Debian .changes file of a just-built package, identifies all reverse-build-dependencies and rebuilds them with the .debs from the .changes file.

The intended use-case is, for example, to package a new snapshot of a Go library and verify that the new version does not break any other Go libraries/binaries.

Installation (from git, for hacking on ratt)

Please install ratt from Debian. In case you want to hack on ratt, you can use the following commands to install Go, download ratt from git and compile/install it into your $GOPATH:

sudo apt-get install golang-go
export GOPATH=~/gocode
go get -u github.com/Debian/ratt

Start the resulting binary in ~/gocode/bin/ratt:

~/gocode/bin/ratt -help

After making changes to the code, to recompile and install it again, use:

go install github.com/Debian/ratt

Usage

Let’s assume you build a new version of a Go library, like so:

debcheckout golang-github-jacobsa-gcloud-dev
cd golang-github-jacobsa-gcloud-dev
dch -i -m 'dummy new version'
git commit -a -m 'dummy new version'
gbp buildpackage --git-pbuilder  

Now you can use ratt to identify and rebuild all reverse-build-dependencies:

$ ratt golang-github-jacobsa-gcloud_0.0\~git20150709-2_amd64.changes

ratt uses sbuild(1) to build packages, see https://wiki.debian.org/sbuild for instructions on how to set up sbuild. Be sure to add --components=main,contrib,non-free to the sbuild-createchroot line in case you want to deal with packages outside of main as well.

Targeting a different suite

Imagine you’re running Debian stable on your machine, but you’re working on a package for Debian unstable (“sid”). Unless you already have configured a corresponding sources.list entry for sid, you will encounter an error message like this:

$ ratt golang-google-grpc_1.11.0-1_amd64.changes
2019/01/19 10:44:34 Loading changes file "golang-google-grpc_1.11.0-1_amd64.changes"
2019/01/19 10:44:34  - 1 binary packages: golang-google-grpc-dev

2019/01/19 10:44:34 Setting -dist=sid (from .changes file)
2019/01/19 10:44:34 Could not find InRelease file for sid . Are you missing sid in your /etc/apt/sources.list?

The most direct solution is to add sid to your /etc/apt/sources.list file, then set Default-Release to stable, so that apt prefers the same packages as before your addition:

# echo 'deb http://deb.debian.org/debian sid main' >> /etc/apt/sources.list
# echo 'APT::Default-Release "stable";' >> /etc/apt/apt.conf
# apt update
$ ratt ...

An alternative solution is to use chdist(1), a tool that allows to create and maintain different apt trees for different suites. Assuming that you have a sid distribution ready in your ~/.chdist, you can then use it by setting the environment variable APT_CONFIG:

APT_CONFIG=~/.chdist/sid/etc/apt/apt.conf ratt ...
