Precondition

a, sudo apt install gnupg pbuilder ubuntu-dev-tools bzr-builddeb apt-file debhelper dh-systemd openstack-pkg-tools

b, GPG key
scp -r /home/hua/.gnupg ubuntu@192.168.100.3:~/
gpg --list-public           # or gpg --gen-key
export GPGKEY=XXXXXX
gpg --send-keys --keyserver keyserver.ubuntu.com $GPGKEY

c, SSH key
ssh-keygen -t rsa
https://launchpad.net/~/+editsshkeys

d, Bazaar
bzr whoami "<Email>"
bzr launchpad-login <lauchpad_id>

Get the source code

a, Add related ppa to /etc/apt/source.list
   ppa info can be found from lanchpad https://launchpad.net/~zhhuabj/+archivesubscriptions
   
b, Import the public key and update the repository
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <public-key>
   sudo apt-get update

c, Get the source code (pls don‘t add other repository when executing this step)
   #Get package from the ppa
   sudo apt-get source <package-name>    
   #Get package from official repo
   #pull-lp-source lsb trusty

   #debcheckout --git-track=‘*‘ nova   #for openstack sru

d, dget *.dsc

Example:

sudo add-apt-repository cloud-archive:kilo
#uncomment deb-src in /etc/apt/sources.list.d/cloudarchive-kilo.list
$ cat /etc/apt/sources.list.d/cloudarchive-kilo.list
deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/kilo main
deb-src http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/kilo main


sudo rm /var/lib/apt/lists/* -vf && sudo apt-get update

rmadison libvirt

sudo apt-cache madison nova-compute  #See all versions
sudo apt-get source nova=1:2015.1.2-0ubuntu2~cloud

当中get-get source相当于:

#https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/kilo-staging/+packages?

field.name_filter=qemu&field.status_filter=superseded&field.series_filter=
wget https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/kilo-staging/+files/qemu_2.2+dfsg-5expubuntu9.6~cloud0.debian.tar.gz
wget https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/kilo-staging/+files/qemu_2.2+dfsg-5expubuntu9.6~cloud0.dsc
wget https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/kilo-staging/+files/qemu_2.2+dfsg.orig.tar.xz
dpkg-source -x qemu_2.2+dfsg-5expubuntu9.6~cloud0.dsc

Patch package

1, quilt configuration
   a, sudo apt-get install quilt devscripts dh-make
   b, Export to bash env
      export QUILT_PATCHES=debian/patches
      export QUILT_NO_DIFF_INDEX=1
      export QUILT_NO_DIFF_TIMESTAMPS=1
      export QUILT_REFRESH_ARGS="-p ab"
      export QUILT_PATCHES=debian/patches
      export QUILT_REFRESH_ARGS="-p ab --no-timestamps --no-index"

#git format-patch -1 2150d5d8e17323bc9fce11903da3afffda211d26
quilt import /bak/openstack/nova/0001-pci-eliminate-DB-lookup-PCI-requests-during-claim.patch

   c, Creating a new patch.
      quilt new test.diff
      quilt add neutron/agent/linux/ovs_lib.py
      quilt refresh
      quilt rename -P test.diff test2.diff
      cat debian/patches/test.diff
      quilt pop -a

   d, For the exsiting patch,
      Put the patch into ‘./debian/patches‘ directory
      Pppend it into ‘./debian/patch/series‘ file
      Use ‘quilt push -a‘ command to push all existing patches onto the source tree.
      quilt refresh

3, changelog
   dch -i #can be changed later by dch -e
   cat debian/changelog
   cat debian/copyright
   cat debian/rules
   cat debian/control

   ppa name format:  <customername>[-<openstack-version>|-<ubuntu-release>]
   changelog format: <upstream-version>hf<lp-bug-number>v<date>.<buildnum>
   dch -b -Dprecise-updates -v1:2014.1.5-0ubuntu1.2hf123456v20150902.0
   nova (1:2014.1.5-0ubuntu1.2hf123456v20150902.0) precise-update; urgency=low
       * [HOTFIX] Fixes some catastrophic failure (LP: #123456)
         - blah blah blah
         - d/p/my-awesome-backport.patch

4, Edit ppa‘s dependancy in ‘Edit PPA dependencies‘ field.
   Eg:
   for Juno,    ~ubuntu-cloud-archive/ubuntu/juno-staging
   for grizzly, ~ubuntu-cloud-archive/grizzly-staging


5, Resolv the dependancy
   dpkg-checkbuilddeps
   
   add grizzly dependancy repository
   #sudo add-apt-repository ppa:ubuntu-cloud-archive/grizzly-staging
   deb http://ppa.launchpad.net/ubuntu-cloud-archive/grizzly-staging/ubuntu precise main
   deb-src http://ppa.launchpad.net/ubuntu-cloud-archive/grizzly-staging/ubuntu precise main
   sudo apt-get build-dep  quantum    # will read debian/control to resolv dependancy.
   sudo apt-get build-dep --no-install-recommends quantum

6, Build
   find . -name "*.pyc" -exec rm -rf {} \;
 
   #build signed source package
   debuild -S -k<your key here>

   #build signed binary package
   debuild -b -k<your key here>

   #build unsigned source package
   debuild -i -us -uc -S

   #build unsigned binary package which can be tested by the command ‘dpkg -i <pac>.deb‘
   debuild -i -us -uc -b

   debuild -S -sa --changes-option=-DDistribution=precise -k<GPGKEY>

   #for openstack sru, 有时候这步不成功，须要先将patch用quilt格式化一下再用（quilt import, quilt push -a, quilt refresh)

   sudo apt install build-essential devscripts quilt dh-autoreconf fakeroot dpkg-dev python-sphinx

   gbp buildpackage -S -k$GPGKEY
   #gbp buildpackage -S -us -uc

2, debiandiff, 这步须要将老新build两次再用debdiff命令产生
   a, Use the existing debdiff, patch -p1 < ../trusty.debdiff
   b, Create new debdiff, http://packaging.ubuntu.com/html/traditional-packaging.html#creating-a-debdiff
      debuild -S                                              #build old source to generate dsc file
      debdiff old.dsc new.dsc                           #generate debdiff by comparing two sources

7, Upload to PPA
   export DEBEMAIL=<email>
   export DEBFULLNAME=<name, e.g. "Zhang">
   #Test PPA can be created in https://launchpad.net/~zhhuabj/+activate-ppa
   dput -f ppa:zhhuabj/trusty-sru-testing test.changes
  
   #openstack sru

git push --all lp:~<launchpad-id>/ubuntu/+source/nova
git push --tags lp:~<launchpad-id>/ubuntu/+source/nova

假设用git的话。须要先在~/.git_config中加入：

[url "git+ssh://zhhuabj@git.launchpad.net/"]
        insteadof = lp:

然后运行：git push lp:~zhhuabj/ubuntu/+source/nova

最后訪问： https://code.launchpad.net/~zhhuabj/ubuntu/+source/nova/+git/nova

wget https://launchpad.net/debian/+archive/primary/+files/libvirt_1.2.14.orig.tar.gz

#注意：上面的是debian包，须要先使用beyond compare工具和ubuntu的1.2.16对debian文件夹进行比較转化成ubuntu包，转换规则是：

1。 凡1.2.14有的，1.2.16没有的。删

2， 凡1.2.14没有的。1.2.16有的，增

3， 凡1.2.14与1.2.16不一致的以1.2.16为准

4。 debian/patch和debian/changlog能够不作处理

5， debian/control也是重点
