* gitk is a great tool for visualizing the git history and seeing where your master or branch is wrt origin:master

# git name-rev is fail

git checkout master
git merge ${CURRENT}
git push origin master
git checkout ${CURRENT}
== Workflow recommendation ==
We recommend the scripts described above.  They implement the following, and save you much typing and potential errors!  Most importantly, do your work in branches, not in master!
# Keep a local master branch which only is a pointer to the gitorious master (does not contain local changes)
# Make development modification in a local branch
# When getting ready to push these changes to the origin try the following
## Do a git pull on master to fetch and merge all changes from gitorious
### '''git checkout master'''
### '''git pull origin master'''
## Do a git rebase of the topic branch onto master - That is with topic checkout do "git rebase master"
### '''git rebase master topic'''
## Fix any conflicts that result
### Edit files
### '''git add -u'''
### '''git rebase --continue'''
## Merge the topic branch - This will result in an fast-forward merge.
### '''git merge topic'''
## git push your local master branch
### '''git push origin master'''
# If for some reason you have ever pushed your development branch to someone else don't rebase it as this is effectively rewriting history
# If you want to keep a record that your local development was made in parallel to some other development, do a git merge instead of git rebase in step 2 of above
=== Create a checkout ===
* git clone git://gitorious.org/tubetk/tubetk.git
=== Stash local changes temporarily ===
* git stash
=== Create a local branch ===
* git branch test
=== Swtich to a local branch ===
* git checkout test
=== Get stashed local changes ===
* git stash pop
=== Update a branch to the remote master's head ===
* git stash
* git rebase origin master
* git stash pop
=== Add to local commit ===
* git add <filename>
* git add -A
=== Push local commit ===
* git push origin master
=== Remove a local branch ===
* git checkout master
* git branch -d <branch>
=== Track a remote branch ===
* "git fetch" (get up to date) or "git pull"
* git branch --track somebranch origin/somebranch
** --track is not needed unless you've set branch.autosetupmerge to false in your config
* git checkout somebranch
* git commit
* git push
** sends changes to origin/somebranch
=== Delete a remote branch ===
* Don't do this unless you're incredibly confident in what you're doing
* git push origin :somebranch
=== Project History ===
* git log        ( To view the history of your changes )
* git log -p    ( To see complete diffs at each step )
* git log --stat --summary  ( To see overview  )
=== Setting up tracked repositories to start pushing ===
#If you have cloned read-only version, do the following first
## git remote rm origin
# Add the proper remote
##git remote add origin git@gitorious.org:tubetk/tubetk.git
# You can push your changes
##git push origin master
=== Three ways to commit to remote/master ===
# Without branching    ( Good for quick changes )
# Branching and merging 
# Branching and rebasing
