NAME

       doc_GIT_md - INTRODUCTION

   BASIC GIT COMMANDS
       git add .
           git commit -a

   BASIC Configuration
       make sure to do:

           git config --global merge.ff false
           git config merge.ff false

   Remote Branches
       To list all remote branches use:

           git-branch -a

       To checkout a remote branch initially use:

           git-checkout -b <branchname> origin/<branchname>

       Once you have done this, it will be a local branch, too. Following remote branches should
       exist:

           master

       This is the development branch. Please try to not work directly on it, but instead you
       should use feature branches. So the only commits on master should be non-fastforward
       merges from features branches. Commits on master should always compile and all test cases
       should pass successfully. (see config option above)

           debian

       Is the branch to be used to build debian packages. It additionally contains the debian
       folder. Only debian related commits should be on the debian branch - otherwise it should
       only contain --no-ff merges from master. (see config option above)

   Local branches
       You should always make your own feature branch with:

           git-checkout -b <feature-branch-name>

       On this branch it is not so important that every commit compiles or all test cases run.

       To merge a branch use (no-fastforward):

           git-merge --no-ff <branchname>

       If you already did some commits, but want them in a branch, you can do:

           git-branch foo
           git reset HEAD^^  (for 2 commits back)
           git reset origin/master

           git-ref-log # recover

   Github
       When doing merge requests our buildserver will build authorized users. If you are not yet
       authorized following question will be asked (by user markus2330):

           Can one of the admins verify if this patch should be build?

       Then one of the admins:

       • fberlakovich

       • manuelm

       • markus2330

       • beku need to confirm by saying: .*add+to+whitelist.* or if just the pull request should
         be checked: .*build+allow.* or if just a single build of the mergerequest should be
         started: jenkins build please or if the bindings job should be started: jenkins build
         bindings please

       If you want any configuration changes, please contact Markus Raab elektra@markus-raab.org
       KDB itself.

       Additionally, we added two other scripts, elektra-mount and elektra-umount which act as
       simple wrappers for kdb mount and kdb umount. That work identically but are more script
       friendly.

   The Full Command
       The full command to use elektra-merge to perform a three-way merge on a file managed by
       ucf is: ucf --three-way --threeway-merge-command elektra-merge <New file>=''>
       <Destination>

       Thats it! As described above, elektra-merge is smart enough to run the whole merge off of
       the information from that command and utilizes the new kdb remount command to do so.

   How-To Integrate
       Integrating elektra-merge into a package that already uses ucf is very easy! In postinst
       you should have a line similar to: ucf <New file>=''> <Destination>

       or perhaps: ucf --three-way <New file>=''> <Destination>

       All you must do is in postinst, when run with the configure option you must mount the
       config file to Elektra: kdb elektra-mount <New file>=''> <Mouting destination>=''>
       <Backend>

       Next, you must update the line containing ucf with the options --three-way and --threeway-
       merge-command like so: ucf --three-way --threeway-merge-command elektra-merge <New
       file>=''> <Destination>

       Then, in your postrm script, during a purge, you must umount the config file before
       deleting it: kdb elektra-umount <name>

       That's it! With those small changes you can use Elektra to perform automatic three-way
       merges on any files that your package uses ucf to handle!

   Example
       Below is a diff representing the changes we made to the samba-common package in order to
       allow automatic configuration merging for smb.conf using Elektra. We chose this package
       because it already uses ucf to handle smb.conf but it frequently requires users to
       manually merge changes across versions. Here is the patch showing what we changed:

           diff samba_orig/samba-3.6.6/debian/samba-common.postinst samba/samba-3.6.6/debian/samba-common.postinst
           92c92,93
           < ucf --three-way --debconf-ok "$NEWFILE" "$CONFIG"
           ---
           > kdb elektra-mount "$CONFIG" system/samba/smb ini
           > ucf --three-way --threeway-merge-command elektra-merge --debconf-ok "$NEWFILE" "$CONFIG"
           Only in samba/samba-3.6.6/debian/: samba-common.postinst~
           diff samba_orig/samba-3.6.6/debian/samba-common.postrm samba/samba-3.6.6/debian/samba-common.postrm
           4a5
           >       kdb elektra-umount system/samba/smb

       As you can see, all we had to do was add the line to mount smb.conf during install, update
       the ucf command to include the new --threeway-merge-command option, and unmount
       system/samba/smb during a purge. It really is that easy!
