Please consider our roadmap and open issues when you start contributing to the project.
Before starting your work on this Icinga Web 2 for Grafana, you should fork the project to your GitHub account. This allows you to freely experiment with your changes. When your changes are complete, submit a pull request. 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 to your GitHub account and clone the repository:
git clone git@github.com:dnsmichi/icingaweb2-module-grafana.git
cd icingaweb2-module-grafana
Add a new remote upstream with this repository as value.
git remote add upstream https://github.com/Mikesch-mp/icingaweb2-module-grafana.git
You can pull updates to your fork's master branch:
git fetch --all
git pull upstream HEAD
Please continue to learn about 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. More details on specific changes:
Once you've finished your work in a branch, please ensure to commit your changes. 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.
Once you've committed your changes, please update your local master branch and rebase your fix/feature branch against it before submitting a PR.
git checkout master
git pull upstream HEAD
git checkout fix/style-detail-view
git rebase master
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
Existing branch:
git push -f origin fix/style-detail-view
You can now either use the hub CLI tool to create a PR, or nagivate 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!
If you accidentally sent in a PR which was not rebased against the upstream master, developers might ask you to rebase your PR.
First off, fetch and pull upstream master.
git checkout master
git fetch --all
git pull upstream HEAD
Then change to your working branch and start rebasing it against master:
git checkout fix/style-detail-view
git rebase master
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
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
git checkout -b fix/style-detail-view-rebase
git rebase master
git branch -D fix/style-detail-view
git checkout -b fix/style-detail-view
git push -f origin fix/style-detail-view
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
You can help test-drive the Git master inside the Icinga 2 Vagrant boxes.
$ git clone https://github.com/Icinga/icinga-vagrant.git
$ cd icinga-vagrant/icinga2x
$ vagrant up
$ vagrant ssh -c "cd /usr/share/icingaweb2/modules/grafana && sudo git pull"
Icinga Web 2 is written in PHP and JavaScript. This module relies on the base framework.
Start your work in a test installation where the module's directory is mounted and you can see codes change in a direct manner.
This is only important for developers who will review pull requests. If you want to join the development team, kindly contact us.
- Ensure that the style guide applies.
- Verify that the patch fixes a problem or linked issue, if any.
- Discuss new features with team members.
- Test the patch in your local dev environment.
If there are changes required, kindly ask for an updated patch.
Once the review is completed, merge the PR via GitHub.
In order to amend the commit message, fix conflicts or add missing changes, you can add your changes to the PR.
A PR is just a pointer to a different Git repository and branch. By default, pull requests allow to push into the repository of the PR creator.
Example for #4956:
At the bottom it says "Add more commits by pushing to the fix/persistent-comments-are-not-persistent branch on TheFlyingCorpse/icinga2."
First off, add the remote repository as additional origin and fetch its content:
git remote add theflyingcorpse https://github.com/TheFlyingCorpse/icinga2
git fetch --all
Checkout the mentioned remote branch into a local branch (Note: theflyingcorpse is the name of the remote):
git checkout theflyingcorpse/fix/persistent-comments-are-not-persistent -b fix/persistent-comments-are-not-persistent
Rebase, amend, squash or add your own commits on top.
Once you are satisfied, push the changes to the remote theflyingcorpse and its branch fix/persistent-comments-are-not-persistent.
The syntax here is git push <remote> <localbranch>:<remotebranch>.
git push theflyingcorpse fix/persistent-comments-are-not-persistent:fix/persistent-comments-are-not-persistent
In case you've changed the commit history (rebase, amend, squash), you'll need to force push. Be careful, this can't be reverted!
git push -f theflyingcorpse fix/persistent-comments-are-not-persistent:fix/persistent-comments-are-not-persistent
