# set up stages

variables:
  GIT_STRATEGY: fetch

stages:
  - change detection
  - get external dependencies
  - build
  - push packages

# define which docker image to use for builds
default:
  image: gitlab.senfcall.de:5050/senfcall-public/docker-bbb-build:v2021-10-12
  
# This stage uses git to find out since when each package has been unmodified.
# it then checks an API endpoint on the package server to find out for which of
# these versions a build exists. If a viable build (from a commit where the
# package is identical) is found, that package name and .deb-filename are
# written to a file `packages_to_skip.txt` the root of the repo. This file is
# passed to the subsequent stages:
# - The jobs in the build stage check whether "their" package is listed in
#   `packages_to_skip.txt` and don't build a new one if it is.
# - The bigbluebutton-build job includes the package versions listed in that
#   file as version-pinned dependencies of the `bigbluebutton` package (instead
#   of the current commit version)
# - The push_packages job sends the filenames of the packages that can be reused
#   to the server, so they are included with the current branch. (Relevant for
#   commits that start a new branch and don't change all packages)
