389 Directory Server: developing administrative tools

Status Proposed - draft
Skill level Intermediate
Skills required Python: Must understand Classes, Inheritance, and Modules
Mentor(s) William Brown (firstyear UTC+10, please be patient!)
Contacts (IRC & email) #389[?] & 389-devel@lists.fedoraproject.org
Idea description

389 Directory Server is an enterprise class LDAP server, used in businesses globally to authenticate and identify people. We have a large code base that has gone through nearly 20 years of evolution.

Part of this evolution has been the recent addition of a python administration framework designed to replace our legacy perl tools. The framework already has the base classes designed and written, but we need help to knit together the high level administrative functionality.

Throughout this process you will need to:

  • Learn to deploy a 389 Directory Server.
  • Learn some of the functions of 389 DS (account policy, plugin management).
  • Read and interpret some of our existing perl and shell scripts.
  • Extend the python tools dsconf to support enabling / disabling / configuration of modules in Directory Server to replace our legacy tools.
  • Review other team members' python code.
  • Participate in our community.

From this you will learn:

  • How to integrate and use existing python frameworks and servers.
  • Techniques to unit test command line and python tools.
  • How to work with a geographically distributed team.
  • Engineering principles expected of a project with high quality demands.
  • Use of git and ticket trackers for a project.
  • How to contribute to mailing lists and the review process.

What are we looking for:

  • To teach you good community engagement, and engineering skills. The coding project is a means to help us teach you to interact effectively with a team, and to learn engineering principles.

Is this project right for you?

  • Come and talk to wibrown on #389 in irc on freenode, or email our mailing list 389-devel@lists.fedoraproject.org

Continuous static analysis db

Status Proposed - draft
Skill level Intermediate
Skills required
  • Python
  • Distributed systems
Mentor(s) Athos Ribiero (athoscr)
Contacts (IRC & email) IRC: athos

Email: athoscribeiro@gmail.com

Idea description

This project proposes the design and implementation of a system to continuously run multiple security oriented static analyzers on source code and display the alarms related to a specific version of the analyzed software. The alarms to be presented will be ranked based on their importance, where critical flaws shall be ranked first and potential false positives are ranked last. We will develop a tool to perform continuous static analysis with different static analyzers and propose a warning classification method using their outputs. We will also propose a visualization approach for the information generated with our tool.

Migrate Plinth to Fedora Server

Status Proposed - draft
Skill level Novice
Skills required
  • Python and Django
  • Git
  • dnf knowledge
  • ARM based hardware is a plus
  • RPM packaging knowledge is a plus
Mentor(s) Tong Hui (first year, UTC+8, please be patient!)
Contacts (IRC & email)
Idea description Plinth is developed by Freedombox which is a Debian based project. The Freedombox is aiming for building a 100% free software self-hosting web server to deploy social applications on small machines. It provides online communication tools respecting user privacy and data ownership, replacing services provided by third-parties that under surveillance. Plinth is the front-end of Freedombox, written in Python.

This idea mainly about migrate Plinth from Deb-based to RPM-based, and make it available for Fedora Server which will running on ARM machines. It would be better of student to be familiar with ARM based hardware and knowing something about how to running a Fedora Server on it, or use something like Qemu if you don't know hardware.

The main goal of this idea is to make Plinth works fine in Fedora Server or Minimal flavor, due to Plinth write APT commands hard coded, so it is better yo make it more adoptive for RPM. The secondary goal is to make a RPM package for Plinth from source and setup a repo for it, so that everyone who use Fedora could use Plinth.

You will learn:

  • how to write modern test driven Python projects
  • how to running Fedora Server on a ARM machine.
  • how to migrate deb package to RPM package from source.

Fedora Media Writer - New Features

Status Proposed - draft
Skill level Intermediate
Skills required C++/Qt and/or QML
Mentor(s) Martin Bříza
Contacts (IRC & email) mbriza on Freenode (for example on #fedora-devel[?] or #fedora-apps[?]) or mbriza@redhat.com
Idea description Fedora Media Writer is a tool that makes putting Fedora images on portable media (such as flash drives) much easier. Since Fedora 25, it is offered as the default download options for users coming to https://getfedora.org from a Mac or a Windows computer.

Ever since the rewrite from liveusb-creator, there has been some features missing from it and due to the popular demand, it wouldn't be a bad idea to get them readded. You won't need to implement all of these. Just one would be perfectly fine. However, please contact me first so we can arrange the details of your potential application.

There is a short list of some things that could be done (however, feel free to get in touch about anything else, or look on the GitHub page for some more):

  • Persistent storage. To explain how it works, I'll start with how live media works now for us: After booting into the live system, you can do whatever you want, install programs, save files to your home folder or even modify the root filesystem, as much as your free memory permits you. However, after rebooting you lose all those changes because the partitions on the drive are not touched. Persistent storage adds the possibility to retain those changes through reboots so you would be able to install new apps to your live environment or work with files stored on the flash drive.
  • Being able to write the images without destroying the data that was already present on the flash drive before.
  • Having a Fedora ARM image resized to fit the size of your SD card immediately after having it written.
  • Proper privilege escalation through launchd for the helper process on macOS.

Understanding of libraries and techniques relevant to this project on Linux, Mac or Windows (or all of them) is a big plus.

You'll learn more about multiplatform development and be involved in the project that is the first thing new users see when they are going to try Fedora.

Adwaita and HighContrast style for QtQuickControls

Status Proposed - draft
Skill level Novice
Skills required QML and a little bit of C++
Mentor(s) Martin Bříza
Contacts (IRC & email) mbriza on Freenode (for example on #fedora-devel[?] or #fedora-apps[?]) or mbriza@redhat.com
Idea description Fedora Workstation ships custom Qt themes that match its Adwaita and Highcontrast themes from its default GNOME desktop environment. This makes Qt applications blend nicely into the overall Fedora Worstation experience.

However, to fully support most of the Qt applications, we need to have QtQuickControls (QML) themes implemented, too.

Work on this would consist of three main parts:

  • Figuring out where and how to install the theme (CMake)
  • Implementing the look of all necessary widgets (QML)
  • Making this theme selected by default when the app runs in GNOME (probably C++, in the QGnomePlatform project)

This project is best suited to a candidate who wants to learn about QML.

Fedora CommOps : Centralized Metrics generation

Status Proposed - draft
Skill level Intermediate
Skills required

Required:

  • Python
  • Basic understanding of APIs
  • Flask

Bonus Skills:

  • Data analytics algorithms
  • Knowledge of Fedora Apps

Idea description

Right now, metrics collection in CommOps is not very efficient and requires a lot of manual work. Metrics for various events/FAS groups/users are collected using scripts which query datagrepper and return results. This process is very time consuming and writing scripts each time is a very tedious process. Also, querying the datagrepper to get data everytime is redundant and time-consuming.

Hack on statscache to build a central metrics generation system for Fedora with handy features to pull statistics. Take a look at the Pagure ticket for more details.
