Rev.1.0
Are you a solo developer ?Even if you are alone, you can improve your productivity.
How not work alone
FTP
Why not ?
• You cannot control versions
• You cannot recover last operative version
• You have to upload all files to be sure that the production version works fine as local works
Or a team ?Some order is needed to go ahead
Ready to jump ?Collaborative development with git
Well, let's go then!
What is GIT ?
What is GIT ?GIT is a source control management (SCM) that
allows developers to have controlled all versions and premises about collaboration
between the team members.!Once you now how it works rarely you will
think in work in other way. The principle is that all the sources reside in a central repository and all members have a copy of it, in local.
Through commands the changes are uploaded/downloaded from/to central repository.
Let's see how works
But … this is all ?

Best practicesDon't use always master branch
• The develop branch is the base • We create a feature branch in order to
develop a new functionality • We can test this functionality locally or in
other pre-staging server • Once all it's OK we have to merge this
feature branch to develop branch, and the deploy in staging server to test the whole product
• Lastly we have to create a release to merge changes on master branch and finally deploy in production

git fetch origin feature:feature
sysadmin, jenkins, automatic deploy, etc
Some commandsFirst learn to use console
Some git commandsclone git clone url folder
branches list local branches: git branch remote branches: git branch -r
get branch git fetch origin remote-branch:local-branch
status git status
stashgit stash git stash list git stash pop git stash clear
processgit add -A git commit -e git pull origin git push origin branch
SamplesHow to use git in the real world
Create a repo in our server• our server has the IP 192.168.1.1
• our git user is gituser
• we have to create a ssh relation*
• git init --bare /var/git/sample.git
Clone in local the repo• git clone gituser@192.168.1.1:/var/git/sample.git /home/user/projects/sample
Create local repository• cd /home/user/projects/sample
• git init
Assign remote in existing local repository
• cd /home/user/projects/sample
• git remote add origin gituser@192.168.1.1/var/git/sample.git
Commit all changes in local
• git add -A
• git commit -m "message to commit"
Update local from remote• git pull origin
all the changes in local files have to be committed or stashed before to use pull.
Save changes in clipboard (stash)
• git stash
stash
See stash's contents• git stash list
stash
Recover last stash• git stash apply # apply changes w/o erasing from stash
• git stash pop # extracts and apply contents from stash
stash
Clear contents of stash• git stash clear
stash
Update remote from local• git push origin branch
before to use push we have to use pull in order to update our local repo with content of remote and resolve posible conflicts first.
Create branch from existing
• git checkout -b new-branch
Merge branch with current
• git merge --no-ff branch-to-merge
commercial gitservers that use git
github.com
• github.com allows to create repositories through its graphic interface
• we can get the url to clone from page just created
• then is as you have a private server
