Workflow for gitorious and github

Initial checkout:

   1 # Fork repo on gitorious/github
   2 # Pull repo from gitorious/github
   3 # Add remote for upstream, e.g.
   4 cd Spoon-Knife
   5 git remote add upstream git://github.com/octocat/Spoon-Knife.git
   6 git fetch upstream

When needing to merge upstream changes back into master:

   1 # Make sure we're in the branch we want to be in (i.e. master)
   2 git checkout master
   3 git fetch upstream
   4 # Merge from master branch of upstream into current branch
   5 git merge upstream/master

Cookbook

Delete remote branch

git push origin :name-of-remote-branch

Reverting changes

Amend the previous commit that has not been propogated (i.e. undo it, then start a new one with the pending changes in the index):

git commit --amend -a -m "New commit message"

Undo a commit that has not been propagated:

git reset --soft HEAD^

just changes the repository without changing the files you've edited on disk. However:

git reset --hard HEAD^

will reset both repository and revert files.

Once a commit that has been propagated, there is no way to undo. However, the following will create a new commit undoing the previous commit's changes:

git revert HEAD

Pull with rebase instead of merge

git pull --rebase

Configure a branch to always do a rebase instead of a merge:

git config branch.master.rebase true

Enforce .gitignore

Remove files from the repository that should have been ignored by .gitignore:

git rm -r --cached .
git add .
git status
git commit -m ".gitignore is now working"

Ignore whitespace bullshit

# Ignore white space when pulling or merging
git pull -Xignore-space-change
git merge -Xignore-space-change

# Ignore white space changes when diff'ing
git diff --ignore-space-change

Per-repository user settings

git config user.name 'Samat K Jain'
git config user.email 'nobody@example.com'
