Rpm Tools

Introduction

In this howto we could let script-tools we need to build rpm

Build a srpm with mock

mock get a special syntax not always easy to recall, here a script that you need to record at /usr/bin/mockbuild (set it executable)

  • mockbuild usage
mockbuild package.src.rpm  mock_configuration

mock_configuration can be found in /etc/mocks 

smeserver-9-x86_64-base smeserver-9-i386-base
smeserver-8-x86_64-base smeserver-8-i386-base

#!/bin/bash
   # who i'm
   ME=$(whoami)
   mkdir -p /home/$ME/exchange

   #test if the second argument is here
   if -z $2 ; then
   echo "################################################"
   echo "you must give as argument the mock configuration"
   echo "   smeserver-9-x86_64-base smeserver-9-i386-base"
   echo "   smeserver-8-x86_64-base smeserver-8-i386-base"
   echo " mockbuild package.src.rpm  mock_configuration  "
   echo "################################################"
   exit
   fi
                                                              
   mock -r $2 --rebuild $1 --resultdir=/home/$ME/exchange/$2
                                          
   # we give the path where are files
   echo ""
   echo "=================================================================================================================="
   echo "RPMS are in /home/$ME/exchange/$2 of your build server"
   echo ""
   ls -1 /home/$ME/exchange/$2/*.rpm
   echo "=================================================================================================================="
                                          
   # and we sign rpm if needed, if not simply do 'enter' with keyboard
   echo ""
   echo "3.Sign your rpms"
   rpm --resign /home/$ME/exchange/$2/*.rpm 2>&1 > /dev/null

A the end I use rpm to sign my rpm, if you don't need it you can remove it.

git_ignore

git don't track empty directory that we may need for a rpm, here a script that you need to record at /usr/bin/git_ignore (set it executable)

usage in the git directory call the script and track all gew files by " git add . && git commit -m 'your-message' " 

git_ignore

#in order to add a .gitignore file to track empty folder
find * -type d -empty -exec touch {}/.gitignore \;

git_mockbuild

a git integration for mock, git and rpm

you can record this script in /usr/bin 

cp git_mockbuild /usr/bin chmod 775 /usr/bin/git_mockbuild

you need to make a folder with the exact name of the rpm (eg smeserver-dhcpmanager). Inside of this folder you create your git repository and work on files and folder of your RPM. Be aware that GIT do not track empty repositories, you have to create a '.gitignore' (even with nothing inside) in each empty directory, if you want they will be incorporated in your GIT repository.

you can use this command line in case of many folders and subfolders 

find * -type d -empty -exec touch {}/.gitignore \;

Once you want to make the RPM then simply use git_mockbuild without arguments in the root folder of your git repository, the architecture of build come from the spec file. But if needed you can choose another build arch. You have to choose one argument. 

git_mockbuild or git_mockbuild sme8-386 sme8-64 sme9-386 sme9-64

by default if the build architecture is not specified in the spec file, it is the case of packages which are not 'noarch', the RPM will be make by mock with the same architecture of your build server. Therefore you have to specify which arch you want if you need another rpm architecture (eg i386 instead of x86_64)

The CentOS target version comes from the GIT branch you created in your GIT repository. For example if your branch is named sme9 then the build is done for el6, else the target CentOS version is el5.

For an automatic build for all architectures you should take considerations about Plague which is done for that.

Each time you execute the script, the GIT branch in use is tagged with the version of the RPM.

The result of build can be find in the 'exchange' folder of the user's home of that script

usage in the git directory of your rpm (you need to install git & mock installed)

contrib_migration

a script to migrate contrib from sme8 CVS to your local git and to your remote Github account for sme9

simply call the script with the name of the cvs directory. Of course you have to install cvs and retrieve the source code in an anonymous or with a developer access

contrib_migration smeserver-wordpress

If the directory is not existed in your git directory (~/git_work) in my server, then we launch the script. After that it creates automatically the new repository in github with your credentials (adjust 'stephdl' with your login account and replace 'xxxxxxxxxxxxxx' with your password) After that the script does several things

  • create the local git repository
  • create the remote github account
  • build all patches and remove them
  • move all perl files to the correct new path
  • test if the new apache authentication is needed and where.
  • add a .git_ignore in empty folders (needed by git)
  • track all that stuff :)
