Goal

Shumgrepper is a web app built on the top of Summershum. Summershum is a project that collects md5sum, sha1sum and sha521sum of every file present in every package. This can be used to check how many packages have the full GPL license, how many files contains a particular hash sum in all Fedora or to check the database in taskotron test, etc. It will bring up lot of new possibilities to developers, system administers and commiters by allowing them to verify the integrity and authenticity of a tarball, package or a individual source file. Not only this, it will help them in identifying changes made in packages and bundles by comparing check-sums. I will develop JSON/API along with Web front-end for the data generated by summershum. It will integrate most of the features of datagrepper along with user friendly real time visualization tool that will show ongoing changes in package hashes. The information related to package hashes is sensitive and can be vulnerable to various attack like DDos, So I will ensure security against it by taking appropriate security preventive measures.

Project Details

The project will mainly be divided into 5 phases.

Phase 1: Query building for Database

In this phase of development I will add methods that will query summershum database to get required data. Adding several arguments to request data from summershum database accordingly. -- One of the filtering arguments can be ‘filename’ which takes filename as value. -- Some other arguments can be ‘pkgname’ (takes package_name as value), tarfile, date,md5sum, sha256sum, sha1sum.<br\> e.g. query for a file can be done as <br\> GET https://apps.fedoraproject.org/shumgrepper?package=datagrepper&filename=app.py Add methods in summershum that will return data according to the argument in the query. Format returned data in human and machine readable output like csv, json.

Phase 2: Web API Wrapper of the app

The development in this part is involved with defining the web API wrapper which involves defining the directory structure of the app. It also involves defining various end-points of the app. The implementation will be done using flask framework. Sample directory structure of the app: shumgrepper\ shumgrepper\ static\ css\ views.css templates\ index.html docs\ __init__.py views.py util.py summershum.models\ # files containing methods that will query summershum fedmsg.d\ # display fedmsg messages in human readable format run.py setup.py Flask has a great similarity with MVC architecture as it contains view (templates), controller (views.py) and the model (summershum). views.py contains definition for various end-points.

Phase 3: Web-Frontend

In this part of development my aim is to build user-friendly web interface. For this, I will use mako template library to build the web-front end for end-points defined in the earlier phase. Apart from this I will also design and build the front page of the app. As discussed earlier the website is suspected to various attack. One of the prominent can be DDoS attack. In order to prevent it, it is important to distinguish between legitimate website visitors and automated or malicious clients. The above mentioned strategies can be implemented in the following steps: Designing the front-end of the page and deciding what information to be displayed. Converting json data into human readable strings using fedmsg.meta functions. Improving styling(css) of the page as per design. Front page may contain an odometer for count of different GPL Licence. Front page may also contain a graph (package name v/s number of times it is bundled). I have made a demo front page: Embed a challenge response(C/R) mechanism in the form of CAPTCHA.

Phase 4: Deployment

In this phase i will deploy the package Shumgrepper in fedora production environment. This will enable users to install it via yum. It involves the following steps: Packaging of Shumgrepper as rpm Deploy the rpm file in fedora staging infrastructure to check if it works there. Push everything out to the fedora production environment.

Phase 5: Integration

It involves integrating the app on other applications and testing it This may require making amendments in the app.

About Me

I’m a Junior student at Indian Institute of Information Technology, Allahabad majoring in Information Technology. I have worked on various projects in C/C++, Java and Python. I am also comfortable with Javascript, PHP, CSS and HTML and other python web development frameworks. I have been using Open Source Softwares from many years but got the chance the contribute to these when I got selected in the Outreach Program for Women internship(Round 7) for a Fedora project Datagrepper. Will you have any other time commitments, such as school work, another job, planned vacation, etc., during the duration of the program? In early May our summer vacation of college will start and ends by late of July; I can give my full time commitment to this project,. I assure dedication of at least 40 hours per week to the work and that I do not have any other obligations from early May till mid August.

Past Experience

I am Firefox Student Ambassador of my college and is involved in raising awareness about Open Source Software, FOSS organisation, Mozilla and its various products. I have always been involved in inspiring friends and juniors to contribute to open source projects. I have also given a talk in my institute to motivate people to apply for 'GSoc and OPW'. Besides this I have also organized many other coding events. Apart from this, I am always interested to get more and more women involved in free and open source software.

OPW internship: Fedora-Datagrepper

Worked on the front-end of Datagrepper i.e. made html cards, improvement in CSS.1 Added an odometer on the front-page that displays the total number of messages. 2 Integrated datagrepper-messages into fedora-packages. 3 Made a Mediawiki extension that enables user to add datagrepper-messages on his/her fedora wiki user page.4 Link to pull requests: Datagrepper Fedora-Packages Blog: http://honeycoding.wordpress.com
