+# Agile and Git
+
+----------
+
+## Agile
+
+Lean software development methods focused on collaboration and interaction
+with fast and smaller deployment cycles.
+
+----------
+
+## Where Git comes in
+
+Git is an excellent tool for an Agile team considering that it allows
+decentralized and simultaneous development.
+
+----------
+
+### Branching And Workflows
+
+Branching in an Agile environment usually happens around user stories with one
+or more developers working on it.
+
+If more than one developer then another branch for each developer is also used
+with his/her initials, and US id.
+
+After its tested merge into master and remove the branch.
+
+----------
+
+## What about GitLab
+Tools like GitLab enhance collaboration by adding dialog around code mainly
+through issues and merge requests.

doc/university/training/topics/bisect.md

+# Bisect	  	
+
+----------
+
+## Bisect
+
+- Find a commit that introduced a bug
+- Works through a process of elimination
+- Specify a known good and bad revision to begin	  	
+
+----------
+
+## Bisect
+
+1. Start the bisect process
+2. Enter the bad revision (usually latest commit)
+3. Enter a known good revision (commit/branch)
+4. Run code to see if bug still exists
+5. Tell bisect the result
+6. Repeat the previous 2 items until you find the offending commit
+
+----------
+
+## Setup
+
+```
+  mkdir bisect-ex
+  cd bisect-ex
+  touch index.html
+  git add -A
+  git commit -m "starting out"
+  vi index.html
+  # Add all good
+  git add -A
+  git commit -m "second commit"
+  vi index.html
+  # Add all good 2
+  git add -A
+  git commit -m "third commit"
+  vi index.html
+```
+
+----------
+
+```
+  # Add all good 3
+  git add -A
+  git commit -m "fourth commit"
+  vi index.html
+  # This looks bad
+  git add -A
+  git commit -m "fifth commit"
+  vi index.html
+  # Really bad
+  git add -A
+  git commit -m "sixth commit"
+  vi index.html
+  # again just bad
+  git add -A
+  git commit -m "seventh commit"
+```
+
+----------
+
+## Commands
+
+```
+  git bisect start
+  # Test your code
+  git bisect bad
+  git bisect next
+  # Say yes to the warning
+  # Test
+  git bisect good
+  # Test
+  git bisect bad
+  # Test
+  git bisect good
+  # done
+  git bisect reset
+```

doc/university/training/topics/cherry_picking.md

+# Cherry Pick
+
+----------
+
+## Cherry Pick
+
+- Given an existing commit on one branch, apply the change to another branch
+- Useful for backporting bug fixes to previous release branches
+- Make the commit on the master branch and pick in to stable
+
+----------
+
+## Cherry Pick
+
+1. Check out a new 'stable' branch from 'master'
+1. Change back to 'master'
+1. Edit '`cherry_pick.rb`' and commit the changes.
+1. Check commit log to get the commit SHA
+1. Check out the 'stable' branch
+1. Cherry pick the commit using the SHA obtained earlier
+
+----------
+
+## Commands
+
+```bash
+git checkout master
+git checkout -b stable
+git checkout master
+
+# Edit `cherry_pick.rb`
+git add cherry_pick.rb
+git commit -m 'Fix bugs in cherry_pick.rb'
+git log
+# Copy commit SHA
+git checkout stable
+
+git cherry-pick <commit SHA>
+```

doc/university/training/topics/feature_branching.md

+# 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
+```

doc/university/training/topics/getting_started.md

+# Getting Started
+
+----------
+
+## Instantiating Repositories
+
+* Create a new repository by instantiating it through
+```bash
+git init
+```
+* Copy an existing project by cloning the repository through
+```bash
+git clone <url>
+```
+
+----------
+
+## Central Repos
+
+* To instantiate a central repository a `--bare` flag is required.
+* Bare repositories don't allow file editing or committing changes.
+* Create a bare repo with
+```bash
+git init --bare project-name.git
+```
+
+----------
+
+## Instantiate workflow with clone
+
+1. 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
+2. Create a '`Workspace`' directory in your home directory.
+3. Clone the '`training-examples`' project
+
+----------
+
+## Commands
+
+```
+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 Workflow
+
+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
+```
+
+----------
+
+## Note
+
+* git fetch vs pull
+* Pull is git fetch + git merge

doc/university/training/topics/git_add.md

+# Git Add
+
+----------
+
+## Git Add
+
+Adds content to the index or staging area.
+
+* Adds a list of file
+```bash
+git add <files>
+```
+* Adds all files including deleted ones
+```bash
+git add -A
+```
+
+----------
+
+## Git add continued

doc/university/training/topics/git_log.md

+# Git Log
+
+----------
+
+Git log lists commit history. It allows searching and filtering.
+
+* Initiate log
+```
+git log
+```
+
+* Retrieve set number of records:
+```
+git log -n 2
+```
+
+* Search commits by author. Allows user name or a regular expression.
+```
+git log --author="user_name"
+```
+
+----------
+
+* Search by comment message.
+```
+git log --grep="<pattern>"
+```
+
+* Search by date
+```
+git log --since=1.month.ago --until=3.weeks.ago
+```
+
+
+----------
+
+## Git Log Workflow
+
+1. Change to workspace directory
+2. Clone the multi runner projects
+3. Change to project dir
+4. Search by author
+5. Search by date
+6. Combine
+
+----------
+
+## Commands
+
+```
+cd ~/workspace
+git clone git@gitlab.com:gitlab-org/gitlab-ci-multi-runner.git
+cd gitlab-ci-multi-runner

doc/university/training/topics/merge_conflicts.md

+# 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'.
+2. Commit and push
+3. Checkout master and edit `conflicts.rb`. Add 'Line6' and 'Line7' below 'Line3'.
+4. Commit and push to master
+5. Create a merge request and watch it fail
+6. Rebase our new branch with master
+7. Fix conflicts on the `conflicts.rb` file.
+8. Stage the file and continue rebasing
+9. Force push the changes
+10. Finally continue with the Merge Request
+
+----------
+
+## Commands
+
+```
+git checkout -b conflicts_branch
+
+# vi conflicts.rb
+# Add 'Line4' and 'Line5'
+
+git commit -am "add line4 and line5"
+git push origin conflicts_branch
+
+git checkout master
+
+# vi conflicts.rb
+# Add 'Line6' and 'Line7'
+git commit -am "add line6 and line7"
+git push origin master
+```
+
+Create a merge request on the GitLab web UI. You'll see a conflict warning.
+
+```
+git checkout conflicts_branch
+git fetch
+git rebase master
+
+# Fix conflicts by editing the files.
+
+git add conflicts.rb
+# No need to commit this file
+
+git rebase --continue
+
+# Remember that we have rewritten our commit history so we
+# need to force push so that our remote branch is restructured
+git push origin conflicts_branch -f
+```
+----------
+
+## Note
+* When to use 'git merge' and when to use 'git rebase'
+* Rebase when updating your branch with master
+* Merge when bringing changes from feature to master
