Debian Packaging
================

We use git-buildpackage for packaging.

Workflow for Unstable
=====================

We use the standard git-buildpackage workflow.

Dynamic Modules
===============

Since v1.9.11 Nginx added dynamic module support. This will sanitize the
nginx packaging flow in the long term, but there is a lot work to be done
in order to get there. We gradually convert all modules to dynamic
as they add support for it.

Workflow for Experimental
=========================

Nginx mainline releases (1.11.x series) are been packaged for experimental,
as they lack security support.

The workflow we use is based on the assumption that packaging work happens on
origin/master and experimental builds are a trivial patch away from that.

The direct consequence of treating experimental as a patchset for origin/master
is that the relevant branches are forced-pushed whenever we release a new
1.11.x version. In other words, **it is not safe to base your work on the
experimental branch**.

This is a brief description of our experimental branches and how we are using
them.

* experimental-base
  Force-pushed when origin/master changes.

  experimental-base tracks the changes needed for building the 1.11.x branch,
  such as new configure parameters, etc. On new 1.11.x releases, it is rebased
  on origin/master so it is always up-to-date with our latest packaging work.

* experimental
  Force-pushed on every 1.11.x release.

  This branch points to the latest 1.11.x release.
  Before release this branch is reset to experimental-base, and then merged
  with the new upstream-1.11 branch. Finally all the release specific changes
  are commited (changelog entry etc) and the build is made.

* upstream-1.11
  Pushed on every 1.11.x release.

  Before a new 1.11.x release origin/upstream is dummy merged (-s ours) into
  ustream-1.11.  This is a technicallity so we can avoid resolving conflicts
  when a new 1.10.x release happens between two experimental releases.

Older 1.11.x releases are not referenced by any branch, but they can be found
by the relevant debian/* tag.
