Usar Pull Request para fazer o merge.
- Revisão do código
- Safe merge
- Integração com Continuous Integration (CI)
$ git checkout master
$ git merge --no-ff --log issue-1
$ git push origin master
copy img sources to assets
$ git checkout -b issue-2
$ # go to work!
$ # commit using gitg
$ git checkout master
$ git merge --no-ff --log issue-2
$ git push origin master
To /home/atila/projects/homepage.git/
! [rejected] master -> master (fetch first)
error: failed to push some refs to '/home/atila/projects/homepage.git/'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Development Workflow
- git hack - cuts a new up-to-date feature branch off the main branch
- git sync - updates the current branch with all ongoing changes
- git new-pull-request - create a new pull request
- git ship - delivers a completed feature branch and removes it
$ git checkout master
$ git sync
$ git hack issue-3
show every step of hack.
obs: fazer o hack de Alice antes de commitar!
Abrir tarefa-3/index.html
$ gitg
Seção de Distribuições GNU/Linux
Fixed #3.
$ git new-pull-request
Para o exemplo usar ship.
$ git checkout master
$ git hack issue-4
Abrir tarefa-4/index.html
$ # add and commit
Seção Ambientes gráficos.
Fixed #4.
$ git ship

To abort, run "git ship --abort".
To continue after you have resolved the conflicts, run "git ship --continue".
$ git ship --abort
undo the commit
$ git log
$ # obter hash do seu commit! algo como 6485209
$ git reset --hard HEAD^
$ git sync

$ git mergetool
Merging:
index.html
Normal merge conflict for 'index.html':
{local}: modified file
{remote}: modified file
Fazer o merge das alterações do remoto com as suas locais.
obs: caso esqueça qual o último commit usar comando git reflog.
$ git commit
[issue-4 188bf6c] Merge commit '6485209' into issue-4
Merge commit, sempre é feito após uma resolução de conflitos.
$ git ship
git ship fez merge --squash, mas também poderia ser feito com
git rebase -i master.
TODO mostrar uso do rebase.
