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.
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/rattStart the resulting binary in ~/gocode/bin/ratt:
~/gocode/bin/ratt -helpAfter making changes to the code, to recompile and install it again, use:
go install github.com/Debian/rattLet’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 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.
