Project to test git flow with multiple users

Setup

• Users: desktop, laptop
• Branches: master, desktop, laptop

Step 1

• desktop create README.md file and create first commit: ‘Initial Commit’

• desktop push to master

  git push --set-upstream origin master

• This should be the first and last time commit is directly pushed to branch origin/master

• Protect branch master by enabling ‘Require pull request reviews before merging’
• Add laptop user as Collaborator

• Create and switch to branch desktop

  git checkout -b desktop

• Create 2 files with 3 lines each: people.md, cars.md

• Commit the 2 files as ‘#desktop - create new files: people and cars’

• Push to origin

  git push --set-upstream origin desktop

• Create pull request ‘#desktop - create new files: people and cars’

Step 2

• laptop accept collaborator invitation

• Clone remote repo

  git clone git@github.com:ijklim/git-multi-users-pull-request.git

• Create and switch to branch laptop

  git checkout -b laptop

• Create 2 files with 3 lines each: people.md, fruits.md

• Commit the 2 files as ‘#laptop - create new files: people and fruits’

• Push to origin

  git push --set-upstream origin laptop

• Create pull request ‘#laptop - create new files: people and fruits’

Step 3

• desktop approves pull-request from laptop ‘#laptop - create new files: people and fruits’
• desktop merge pull-request into branch master
• Status of pull-request ‘#desktop - create new files: people and cars’ changes

• Commit screenshots and README.md changes to branch desktop as ‘#desktop - add screenshots and update README’

• Switch to master, pull from remote origin

  git checkout master
git pull

  Result:

  Updating 2471afd..6e0febc
  Fast-forward
  fruits.md | 3 +++
  people.md | 3 +++
  2 files changed, 6 insertions(+)
  create mode 100644 fruits.md
  create mode 100644 people.md

  git log --oneline

  Result:

  6e0febc (HEAD -> master, origin/master) Merge pull request #2 from ijklim/laptop
  c94164a (origin/laptop) #laptop - create new files: people and fruits
  2471afd Initial commit

• Switch back to desktop and attempt to pull changes from local master

  git checkout desktop
git log --oneline

  Result:

  a4d8c19 (HEAD -> desktop) #desktop - add screenshots and update README
  41f3b80 (origin/desktop) #desktop - create new files: people and cars
  2471afd Initial commit

  git merge master

  Result:

  Auto-merging people.md
  CONFLICT (add/add): Merge conflict in people.md
  Automatic merge failed; fix conflicts and then commit the result.

• With merge conflict, cancel merge and use rebase instead

  git merge --abort
git merge rebase master

  Result:

  First, rewinding head to replay your work on top of it...
  Applying: #desktop - create new files: people and cars
  error: Failed to merge in the changes.
  Using index info to reconstruct a base tree...
  Falling back to patching base and 3-way merge...
  Auto-merging people.md
  CONFLICT (add/add): Merge conflict in people.md
  Patch failed at 0001 #desktop - create new files: people and cars
  The copy of the patch that failed is found in: .git/rebase-apply/patch
  Resolve all conflicts manually, mark them as resolved with
  "git add/rm <conflicted_files>", then run "git rebase --continue".
  You can instead skip this commit: run "git rebase --skip".
  To abort and get back to the state before "git rebase", run "git rebase --abort".

• Fix conflict in file people.md and continue

  git add people.md
git rebase --continue

• Push to remote desktop, use flag —force to override

  git push --force

Step 4

• laptop approve pull-request ‘#desktop - create new files: people and cars’
• laptop merge pull-request ‘#desktop - create new files: people and cars’

• Switch to master, pull changes from remote origin

  git pull
git log --oneline

  Result:

  f9edf4b (HEAD -> master, origin/master, origin/HEAD) Merge pull request #1 from ijklim/desktop
  73d8382 (origin/desktop) #desktop - add screenshots and update README
  a0f435d #desktop - create new files: people and cars
  6e0febc Merge pull request #2 from ijklim/laptop
  c94164a (origin/laptop, laptop) #laptop - create new files: people and fruits
  2471afd Initial commit

• Switch to laptop and pull changes from master

  git checkout laptop
git log --online

  Result:

  c94164a (HEAD -> laptop, origin/laptop) #laptop - create new files: people and fruits
  2471afd Initial commit

  git merge master
git log --online

  Result:

  f9edf4b (HEAD -> laptop, origin/master, origin/HEAD, master) Merge pull request #1 from ijklim/desktop
