build package with cowbuilder or git-buildpackage on Jenkins
#!/usr/bin/python
# -*- coding: utf-8 -*-
''' debbuild_wrapper.py
The debian package build wrapper on Jenkins.
This script support three way of building debian package.
1-1. Backport from source package with cowbuilder.
1-2. Pre-build and Backport from source package with cowbuilder.
2. Build original package with git-buildpackage.
Support flavors are "debian" or "ubuntu".

コードで対応する方法が現時点ではわからないので、とりあえずディストロ毎に、repreproで何か最低限一つ登録しておく、というワークアラウンドをとることにした。

by hand tasks

  • 最低限一つはrepreproにパッケージを登録する
  • Debian, Ubuntu用のpbuilder/cowbuilder イメージをそれぞれDebian/Ubuntu上で作成した後、Debian -> Ubuntu, Ubuntu -> Debianにコピーする
  • 各イメージの apt lineにdebian-security, -{security,updates}, および各-customを追加する

登録できたりできなかったりする問題は、登録状態でも発生したので、そもそもsubprocessで行うのをやめて、pexpectで処理することにした。

複数ディストリビューションに対応する場合(wheezy, jessieとか、precise, trustyとか) は、repreproのpoolでバッティングするので、debian versionを変更しないとアカン問題。
