This section collects a handful of useful commands that may become critical
 
to guarantee the quality of the release. The descriptions below are quite
 
technical and intended for the developers and maintainers only.
 
 
 
==Creating and working with git branches==
 
 
 
Some basic git commands to create and work with branches:
 
 
 
Check in your local repository which branch you are in:
 
 
 
  %git branch
 
* master
 
 
 
Check the branches of your project in the remote repository:
 
 
 
%git branch -r
 
  origin/HEAD
 
  origin/master
 
 
 
Create a new branch called test:
 
 
 
%git checkout -b test
 
Switched to a new branch "test"
 
%git branch 
 
  master
 
* test
 
 
 
Work on files in that branch:
 
 
 
%vi test.txt
 
 
Verify the status of files you modified in that branch:
 
 
 
%git status
 
  # On branch test
 
  # Untracked files:
 
  #  (use "git add <file>..." to include in what will be committed)
 
  #
 
  #      test.txt
 
  nothing added to commit but untracked files present (use "git add" to track)
 
 
 
Add the file(s) edited to the git stage area:
 
 
 
%git add test.txt
 
%git status
 
  # On branch test
 
  # Changes to be committed:
 
  #  (use "git reset HEAD <file>..." to unstage)
 
  #
 
  #      new file:  test.txt
 
  #
 
 
 
Commit your changes to your local repository:
 
 
 
%git commit -m "test file only"
 
  Created commit 14644af: test file only
 
  1 files changed, 1 insertions(+), 0 deletions(-)
 
  create mode 100644 test.txt
 
 
 
Now you want to push these changes to a remote repository that you have
 
writing permission:
 
 
 
%git push origin test
 
 
 
Note however that, unless git is configured so, your local branch of "test"
 
does not track any changes committed by others to the remote branch "test".  
 
Maybe the simplest way to proceed then is just to delete your local branch:
 
 
 
%git branch -D test
 
Deleted branch test.
 
 
 
and checkout the remote branch you just created but letting git know you want
 
to track remote changes to that branch as well:
 
 
 
%git checkout --track -b test origin/test
 
 
 
You may want to see how two branches differ or how your modifications of the
 
branch compare to the HEAD of the branch, for example. Suppose you just
 
added the test.txt file to the staged git area called the index. To know
 
the difference between the index and the HEAD, essentially what would be
 
committed if 'git commit' is issued, just use git diff as follows:
 
 
 
%git diff  --cached
 
  diff --git a/test.txt b/test.txt
 
  new file mode 100644
 
  index 0000000..373c7b0
 
  --- /dev/null
 
  +++ b/test.txt

Release Process

This page describes the release process in some detail. Getting a release out of the door without embarrassing oversights requires a bit more planning and care than one would like.

Long-term planning

A few months or weeks before the release:

  • Decide it is time to make another release
  • Choose features which are going to be included, and those which won't be included
  • Choose a tentative date
  • Begin discussions on the mailing list, reminding people to look at test cases, review patches etc.

One or two weeks before the release

  • Set up a wiki planning page for the release
  • Ask for volunteers, assign tasks to people
  • Review thorns for code quality, documentation, test cases
  • Decide on a thorn list
  • Decide on a list of release-critical systems
  • Collect list of new features, newsworthy items, and acknowledgements for release announcement on wiki
  • Choose a concrete date
  • Announce date publicly
