NAME¶dgit - tutorial for package maintainers already using git-buildpackage(1)
INTRODUCTION¶This document explains how dgit can be incorporated into a git-buildpackage(1) package-maintenance workflow. This should be read jointly with git-buildpackage(1)'s documentation. Some reasons why you might want to incorporate dgit into your existing workflow:
- Benefit from dgit's safety catches. In particular, ensure that your upload always matches exactly your git HEAD.
- Provide a better, more detailed git history to downstream dgit users, such as people using dgit to do an NMU (see dgit-nmu-simple(7) and dgit-user(7)).
Note that we assume a patches-unapplied repository: the upstream source committed to the git repository is unpatched. git-buildpackage(1) can work with patched-applied repositories, but is normally used with patches-unapplied.
GIT CONFIGURATION¶If you run
% git config dgit.default.quilt-mode gbp
in your repository, you can omit --gbp wherever it occurs below.
Note that this does require that you always work from your gbp master branch, never the dgit patches-applied branch.
BUILDING¶You can perform builds like this:
% dgit [--allow-dirty] gbp-build [OPTIONS]
where --allow-dirty is needed for testing uncommitted changes, and OPTIONS are any further options to be passed on to gbp-buildpackage(1).
When you are ready to build for upload, you will probably want to use sbuild(1) or pbuilder(1), or do a source-only upload. Either
% dgit --rm-old-changes --gbp sbuild
% dgit --rm-old-changes gbp-build --git-pbuilder
% dgit --rm-old-changes --gbp build-source
We use --rm-old-changes to ensure that there is exactly one changes file corresponding to this package, so we can be confident we're uploading what we intend (though dgit push will do some safety checks).
Note that all of the commands in this section are not required to upload with dgit. You can invoke gbp-buildpackage(1), pbuilder(1) and sbuild(1) directly. However, the defaults for these tools may leave you with something that dgit will refuse to upload because it doesn't match your git HEAD. As a general rule, leave all signing and tagging to dgit.
UPLOADING¶Don't use --git-tag: dgit push will do this for you. To upload:
% dgit --gbp push
This will push your git history to the dgit-repos, but you probably want to follow it up with a push to alioth.
You will need to pass --overwrite if the previous upload was not performed with dgit.
INCORPORATING NMUS¶dgit pull can't yet incorporate NMUs into patches-unapplied gbp branches. You can just apply the NMU diff the traditional way. The next upload will require --overwrite.
