# Agenda
1. Brief history of Git
1. GitLab walkthrough
1. Configure your environment
1. Workshop
---
# Git introduction
https://git-scm.com/about
- Distributed version control
- Does not rely on connection to a central server
- Many copies of the complete history
- Powerful branching and merging
- Adapts to nearly any workflow
- Fast, reliable and stable file format
---
# Help!
Use the tools at your disposal when you get stuck.
- Use '`git help <command>`' command
- Use Google
- Read documentation at https://git-scm.com

# Configure your environment
- Windows: Install 'Git for Windows'
> https://git-for-windows.github.io
- Mac: Type '`git`' in the Terminal application.
> If it's not installed, it will prompt you to install it.
- Debian: '`sudo apt-get install git-all`'
or Red Hat '`sudo yum install git-all`'

# Git Workshop
## Overview
1. Configure Git
1. Configure SSH Key
1. Create a project
1. Committing
1. Feature branching
1. Merge requests
1. Feedback and Collaboration
---
# Configure Git
One-time configuration of the Git client
```bash
git config --global user.name "Your Name"
git config --global user.email you@example.com
```
---
# Configure SSH Key
```bash
ssh-keygen -t rsa -b 4096 -C "you@computer-name"
```
```bash
# You will be prompted for the following information. Press enter to accept the defaults. Defaults appear in parentheses.
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/you/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/you/.ssh/id_rsa.
Your public key has been saved in /Users/you/.ssh/id_rsa.pub.
The key fingerprint is:
39:fc:ce:94:f4:09:13:95:64:9a:65:c1:de:05:4d:01 you@computer-name
```
Copy your public key and add it to your GitLab profile
```bash
cat ~/.ssh/id_rsa.pub
```
```bash
ssh-rsa AAAAB3NzaC1yc2EAAAADAQEL17Ufacg8cDhlQMS5NhV8z3GHZdhCrZbl4gz you@example.com
```
---
# Create a project
- Create a project in your user namespace
- Choose to import from 'Any Repo by URL' and use
https://gitlab.com/gitlab-org/training-examples.git
- Create a '`development`' or '`workspace`' directory in your home directory.
- Clone the '`training-examples`' project
---
# Commands
```
mkdir ~/development
cd ~/development
-or-
mkdir ~/workspace
cd ~/workspace
git clone git@gitlab.example.com:<username>/training-examples.git
cd training-examples
```
---
# Git concepts
**Untracked files**
New files that Git has not been told to track previously.
**Working area**
Files that have been modified but are not committed.
**Staging area**
Modified files that have been marked to go in the next commit.
---
# Committing
1. Edit '`edit_this_file.rb`' in '`training-examples`'
1. See it listed as a changed file (working area)
1. View the differences
1. Stage the file
1. Commit
1. Push the commit to the remote
1. View the git log
---
# Commands
```
# Edit `edit_this_file.rb`
git status
git diff
git add <file>
git commit -m 'My change'
git push origin master
git log
```
---
# Feature branching
- Efficient parallel workflow for teams
- Develop each feature in a branch
- Keeps changes isolated
- Consider a 1-to-1 link to issues
- Push branches to the server frequently
- Hint: This is a cheap backup for your work-in-progress code
---
# Feature branching
1. Create a new feature branch called 'squash_some_bugs'
1. Edit '`bugs.rb`' and remove all the bugs.
1. Commit
1. Push
---
# Commands
```
git checkout -b squash_some_bugs
# Edit `bugs.rb`
git status
git add bugs.rb
git commit -m 'Fix some buggy code'
git push origin squash_some_bugs
```
---
# Merge requests
- When you want feedback create a merge request
- Target is the ‘default’ branch (usually master)
- Assign or mention the person you would like to review
- Add 'WIP' to the title if it's a work in progress
- When accepting, always delete the branch
- Anyone can comment, not just the assignee
- Push corrections to the same branch
---
# Merge requests
**Create your first merge request**
1. Use the blue button in the activity feed
1. View the diff (changes) and leave a comment
1. Push a new commit to the same branch
1. Review the changes again and notice the update
---
# Feedback and Collaboration
- Merge requests are a time for feedback and collaboration
- Giving feedback is hard
- Be as kind as possible
- Receiving feedback is hard
- Be as receptive as possible
- Feedback is about the best code, not the person. You are not your code
---
# Feedback and Collaboration
Review the Thoughtbot code-review guide for suggestions to follow when reviewing merge requests:
[https://github.com/thoughtbot/guides/tree/master/code-review](https://github.com/thoughtbot/guides/tree/master/code-review)
See GitLab merge requests for examples:

# Tags
- Useful for marking deployments and releases
- Annotated tags are an unchangeable part of Git history
- Soft/lightweight tags can be set and removed at will
Fixed typos
2018-04-27 04:50:05 -04:00
- Many projects combine an annotated release tag with a stable branch
Added training material
2016-10-20 06:38:32 -04:00
- Consider setting deployment/release tags automatically
---
# Tags
- Create a lightweight tag
- Create an annotated tag
- Push the tags to the remote repository

---
# Commands
```
git checkout master
# Lightweight tag
git tag my_lightweight_tag
# Annotated tag
git tag -a v1.0 -m ‘Version 1.0’
git tag
git push origin --tags
```
---
# Merge conflicts
- Happen often
- Learning to fix conflicts is hard
- Practice makes perfect
- Force push after fixing conflicts. Be careful!
---
# Merge conflicts
1. Checkout a new branch and edit `conflicts.rb`. Add 'Line4' and 'Line5'.
1. Commit and push
1. Checkout master and edit `conflicts.rb`. Add 'Line6' and 'Line7' below 'Line3'.
1. Commit and push to master
1. Create a merge request
---
# Merge conflicts
After creating a merge request you should notice that conflicts exist. Resolve
the conflicts locally by rebasing.
```
git rebase master
# Fix conflicts by editing the files.
git add conflicts.rb
git commit -m 'Fix conflicts'
git rebase --continue
git push origin <branch> -f
```
---
# Rebase with squash
You may end up with a commit log that looks like this:
```
Fix issue #13
Test
Fix
Fix again
Test
Test again
Does this work?
```
Squash these in to meaningful commits using an interactive rebase.
---
# Rebase with squash
Squash the commits on the same branch we used for the merge conflicts step.
```
git rebase -i master
```
In the editor, leave the first commit as 'pick' and set others to 'fixup'.
