On the automation of API writing and XML-RPC serving for Python Django

While searching for solutions on adopting Django for the server side of our Dynamic Car Pooling system, I found two very interesting projects:

  • WAPI – a framework which abstracts the details involved in publishing an API and translates class methods to API methods, serializing the objects returned when possible. WAPI handles authentication, too, and other advanced functions. It’s an amazing, fully Django compatible system that currently works over ReST (JSON, XML, YAML) but not with XML-RPC. Therefore, I contacted the author to have some information about the status of the project. It would be very interesting in our system, to provide API and XML-RPC services just by using his layer
  • RPC4Django – provides XML-RPC and JSON-RPC support to an existing Django project. It promises a XML-RPC interface by just adding the decorator @rpcmethod to an existing python function. It also fully integrates with Django authentication framework

I’m going to experiment with these two tools. Obviously the first one is the most interesting because of its ability to “export” services in more formats. But the most important protocol for us is missing. Let’s hope it will be added soon!

First outcomes on DyCaPo

My first day at FBK has just finished, so there are some updates. I’ve uploaded about every document to the Wiki regarding my analysis of the papers. The Analysis Grid is available for view and as a PDF file. Chek them out at http://www.opensocialcapital.com/dynamic_carpooling/wiki/!
For the next week I’m going to review some existing mobile application. I will also contact some Opentrip members to ask them about the status of their work. I will contact the author of dynamicridesharing.org Wiki to ask him some information.

BD-incollo 0.9 is out!

It took me about one year to find some time to enhance my project BD-incollo. I worked hard for 5 days and to add new features and fight the (huge) amount of spam that was wasting my database space. Now I’m very proud to announce bd-incollo 0.9, a free, light, speedy, anonymous Pastebin clone written in Python Django. This version introduces a lot of new features, including the possibility to make diffs between pastes, and fights spam using Akismet. Read more about the features on the project page and on the new News section on the website that makes use of BD-incollo, incollo.com .

BD-incollo 0.9 is free software as always, under the Gnu Affero General Public License 3.

Currently, you can:

  • Copy, Paste and store a text / source code snippet to the system
  • NEW! Give other people the possibility to discover your Paste (make a Paste either public or private)
  • Decide to colorize the syntax of the Paste
  • Share it using its URL
  • NEW! Enhance Pastes! Create a Paste starting from an old one
  • NEW! View differences! Makes use of the powerful diff-match-patch by Neil Fraser to see differences between two Pastes
  • NEW! Antispam protection using Akismet and akismet.py by Michael Foord
  • Download it as plain text
  • View it as plain text
  • Search something interesting through other pastes!
  • Report abuses to site admins

It also uses a very smart hash system that automatically re-computes a hash key in case of collision.

Here is an example of Paste: http://incollo.com/f341e6a4b
Here is an example of enhancement of the Paste: http://incollo.com/ba22929ac
Here is a full-screen diff of the Pastes: http://incollo.com/compare/f341e6a4b/ba22929ac

Play with them! Use incollo.com, spread it!

Road to 1.0

1.0 development will start after my next examination session (on September) and will surely include:

  • Some asynchronous improvements
  • The possibility to teach Akismet about Spam and Ham in Pastes (when admin user is logged in)
  • More cleaner code
  • The possibility to associate a user to its Pastes via a Cookie (always anonymous) and let him delete them
  • Comments to snippets?
  • What else? Contact me if you’ve got ideas!

Introduction To Software Testing

Elements and Concepts – A brief overview

Download PDF version of the whole document. You can browse the article online but I encourage the download of the PDF since it is written with accuracy.

Introduction

This document contains some basic concepts and definitions about software testing. It has been written for studying a part of the Software Engineering Project course at my University. It is composed by a summary of the intersection of more than 10 different sources, all of which are cited. If you feel that some contents of this publication belong to your intellectual property and it is not cited, please contact the author who is willing to correct any mistake.

The first part of the paper focuses on the definition of the most important key aspects of software testing. Then some information about input partitioning are given. What follows is a research about code coverage and two useful and famous tools, Control-flow coverage and Data-flow analysis. A complete example on using those tools is then given. The second half of the document also contains the definition of the most important software testing practices.

The goal of this tiny document is to clarify key terms and therefore become a base start for the reader to go in deep with the interested topics. Another goal is to give a simple but clear example about data flow analysis, as I realized that not all the people understand the examples around the Net.

Software Testing

Software Testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test, with respect to the context in which it is intended to operate. Software Testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs. It can also be stated as the process of validating and verifying that a software program/application/product meets the business and technical requirements that guided its design and development, so that it works as expected and can be implemented with the same characteristics. 1

What is taking me busy – Pomotux!

I’m currently pressed by my University life, that’s because I don’t post often.
There are 3 big projects for this semester: a C compiler, a dynamic website using Java Servlets and JSP and the most interesting one: a C++ program for Software Engineering Project course.
I’m working with other two collegues on a task manager for people using the Pomodoro Technique by Francesco Cirillo.
The project is called Pomotux and is under development following strong software engineering methodologies (Scrum@Xp). Pomotux is under construction since 2 months and uses technologies such as SQLite to store and play with tasks. The interesting fact regarding our data structure choice is that we are also using a framework for obtaining ORM, called LiteSQL.

LiteSQL is a C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer

LiteSQL is still young and immature but powerful enough for our scope. We are also happy to provide feedback to their developers, that are ready to help us. They even wrote a patch for us!
Pomotux is reaching an unexpected stability. Unexpected because it is written by 3 young people that come from a light Java experience and saw C++ 3 months ago. It works under Linux and its graphical interface uses QT 4.5.0. It should work on any *NIX variant that meets dependencies, but also under Windows with some light modifications.
It will support just the basic features of the technique (unfortunately we don’t have the time to fully work on it) but it’s ready for expansions such as team support and statistics.
We will be happy to release the sources as soon as we finish the course, hoping that people will find it useful and that some serious programmers take it and make it the perfect tool for Pomodorians :) I will also contact the author of the Pomodoro Technique when we release it.

    • HEAD
    • PUT
    • POST
    • DELETE
    • TRACE
    • CONNECT
    • OPTIONS
  • Message Headers
    • Request Headers – all
    • Response Headers – all
  • Status Codes:
    • 1xx Information
    • 2xx Success
    • 3xx Redirection
    • 4xx Client error
    • 5xx Server Error
  • Sessions:
    • Cookies
    • Server-Side sessions
  • Secure HTTP – HTTPS:
    • By URI scheme
    • HTTP Upgrade Header
    • SSL/TLS

You can browse an HTML version online.
