This allows you to freely experiment with your changes. +When your changes are complete, submit a [pull request](https://help.github.com/articles/using-pull-requests/). +All pull requests will be reviewed and merged if they suit some general guidelines: + +* Changes are located in a topic branch +* For new functionality, proper tests are written +* Changes should follow the existing coding style and standards + +Please continue reading in the following sections for a step by step guide. + +## Fork the Project + +[Fork the project](https://help.github.com/articles/fork-a-repo/) to your GitHub account +and clone the repository: + +``` +git clone git@github.com:jdoe/icingadb-web.git +cd icingadb-web +``` + +Add a new remote `upstream` with this repository as value. + +``` +git remote add upstream https://github.com/icinga/icingadb-web.git +``` + +You can pull updates to your fork's default branch: + +``` +git fetch --all +git pull upstream HEAD +``` + +Please continue to learn about [branches](#branches). + +## Branches + +Choosing a proper name for a branch helps us identify its purpose and possibly +find an associated bug or feature. +Generally a branch name should include a topic such as `fix` or `feature` followed +by a description and an issue number if applicable. Branches should have only changes +relevant to a specific issue. + +``` +git checkout -b fix/service-template-typo-1234 +git checkout -b feature/config-handling-1235 +``` + +Continue to apply your changes and test them.

A good commit message includes a short topic, additional body +and a reference to the issue you wish to solve (if existing). + +Fixes: + +``` +Fix missing style in detail view + +refs #4567 +``` + +Features: + +``` +Add DateTime picker + +refs #1234 +``` + +You can add multiple commits during your journey to finish your patch. +Don't worry, you can squash those changes into a single commit later on. + +## Pull Requests + +Once you've committed your changes, please update your local default +branch and rebase your fix/feature branch against it before submitting a PR. + +``` +git checkout main +git pull upstream HEAD + +git checkout fix/style-detail-view-5678 +git rebase main +``` + +Once you've resolved any conflicts, push the branch to your remote repository. +It might be necessary to force push after rebasing - use with care! + +New branch: +``` +git push --set-upstream origin fix/style-detail-view-5678 +``` + +Existing branch: +``` +git push -f origin fix/style-detail-view-5678 +``` + +You can now either use the [hub](https://hub.github.com) CLI tool to create a PR, or navigate +to your GitHub repository and create a PR there. + +The pull request should again contain a telling subject and a reference +with `fixes` to an existing issue id if any. That allows developers +to automatically resolve the issues once your PR gets merged. + +``` +hub pull-request + +<a telling subject> + +fixes #1234 +``` + +Thanks a lot for your contribution! + + +### Rebase a Branch + +If you accidentally sent in a PR which was not rebased against the upstream default branch, +developers might ask you to rebase your PR. + +First off, fetch and pull the default branch. + +``` +git checkout main +git fetch --all +git pull upstream HEAD +``` + +Then change to your working branch and start rebasing it against the default: + +``` +git checkout fix/style-detail-view-5678 +git rebase main +``` + +If you are running into a conflict, rebase will stop and ask you to fix the problems. + +``` +git status + + both modified: path/to/conflict.php +``` + +Edit the file and search for `>>>`. Fix, build, test and save as needed. + +Add the modified file(s) and continue rebasing. + +``` +git add path/to/conflict.php +git rebase --continue +``` + +Once succeeded ensure to push your changed history remotely. + +``` +git push -f origin fix/style-detail-view-5678 +``` + + +If you fear to break things, do the rebase in a backup branch first and later replace your current branch. + +``` +git checkout fix/style-detail-view-5678 +git checkout -b fix/style-detail-view-5678-rebase + +git rebase main + +git branch -D fix/style-detail-view-5678 +git checkout -b fix/style-detail-view-5678 + +git push -f origin fix/style-detail-view-5678 +``` + +### Squash Commits + +> **Note:** +> +> Be careful with squashing. This might lead to non-recoverable mistakes. +> +> This is for advanced Git users. + +Say you want to squash the last 3 commits in your branch into a single one. + +Start an interactive (`-i`) rebase from current HEAD minus three commits (`HEAD~3`). + +``` +git rebase -i HEAD~3 +``` + +Git opens your preferred editor. `pick` the commit in the first line, change `pick` to `squash` on the other lines. + +``` +pick e4bf04e47 Fix style detail view +squash d7b939d99 Tests +squash b37fd5377 Doc updates +``` + +Save and let rebase to its job. Then force push the changes to the remote origin. + +``` +git push -f origin fix/style-detail-view-5678 +``` + + +## Testing + +TBD + +## Source Code Patches + +Icinga DB Web is written in PHP, LESS and JavaScript. + +## Documentation Patches + +The documentation is written in GitHub flavored [Markdown](https://guides.github.com/features/mastering-markdown/). +It is located in the `doc/` directory and can be edited with your preferred editor.
