| = Python Implementation of the Data Access Protocol = (Roberto Antonio Ferreira De Almeida) The Data Access Protocol (DAP) is a data transmission protocol designed specifically for science data. The protocol relies on the widely used HTTP and MIME standards, and provides data types to accommodate gridded data, relational data, and time series, as well as allowing users to define their own data types. The initiative is funded by NASA, and counts with the support of several institutions. Hundreds of scientific datasets are available on the internet through DAP servers, which can be accessed remotely by DAP clients in a transparent and efficient way. Here I propose to develop a Python implementation of the protocol based on its latest specification. The proposed implementation will consist of a client module that will allow Python applications to access remote datasets, as well as a server for data stored in a variety of formats commonly used by the scientific community, including NetCDF and Matlab files. Mentor: Paul DuBois. = Bitten: A Python framework for collecting software metrics from automated builds = (Christopher Lenz) The goal of this work is to design and implement a distributed system for automated builds and continuous integration that allows the central collection and storage of software metrics generated during the build. The information collected this way needs to be structured and available in a machine-readable format, so that it can be analyzed, aggregated/correlated and presented after the build itself has completed. Mentors: Greg Wilson, Trent Mick. = OpenExVis - A Program Visualization Tool = (Tero Kuusela) The goal is to write, in Python, a functional program visualization tool that can visualize Python code. With the visualization tool, one can write a program and see the execution visualized to help understanding how the program works. This is especially useful to assist students learning how to program. Mentor: David Ascher. = Object-Oriented File System Virtualisation = (Adam Kerz) Create an object oriented model of a file system in Python that can be used to interface many different resource types (with appropriate implementations). Mentor: Trent Mick. = Wax GUI for Python = (Abhishek Reddy) Wax requires work on four broad fronts. Firstly, support for several basic controls need to be added, some of which are listed above. Secondly, the design of the whole module has to be reviewed, particularly focusing on the initialisation. Thirdly, there are teething problems with passing data between Wax and wxPython that must be looked at. Fourthly, documentation, presently lacking, needs to be written. Mentor: Hans Nowak = PyTrails = (Jennifer Dozar) I'm working on an extensible opensource engine for implementing trail-style games such as Oregon Trail or Amazon Trail. The primary goal is to produce a quality edutainment title that can be used free of cost. The secondary goal is to make it easy for other edutainment trail games to be created. PyTrails will be Python based and uses PyGame. The engine will allow following a branching map including making stops to rest, hunt, or trade. Additional choices such as shopping and fording rivers may be available at special points. Each of these activities will be replacable in other trail games as to allow for maximum flexibility. Mentors: Cameron Laird, Andrew Kuchling = mmpy -- A garbage collection tool kit in Python = (Carl Friedrich Bolz) The project aims at producing a framework for writing and evaluating garbage collectors in Python. The interfaces to the low level memory and to the object model will be general enough to make it usable for a wide range of projects in need for garbage collection as well as for teaching and research purposes. It will be designed with flexibility and modularity in mind to encourage component reuse. It aims a being directly useful for the PyPy project and translatable by its translation tools. Mentors: Samuele Pedroni, Armin Rigo = Efficiently Analysing Data Polymorphism and Deducing Generics in Shedskin = (Mark Dufour) As part of my Master's Thesis, I am working on a Python-to-C++ compilation system, called Shedskin. Currently, it performs static type inference based on two techniques. The Cartesian Product Algorithm is used to handle parametric polymorphism (calling functions with different combinations of argument types); single-level class duplication, or 1CFA, is employed to handle data polymorphism (mostly polymorphic containers, such as list; in 1CFA, each allocation site gets its own class type, so we can analyze these (somewhat) precisely.) Run-time checks such as 'isinstance' are considered during inference. Further, short tuples are analyzed internally, which of course is especially important in case of Python. Based on the statically determined type information, the compiler currently performs stack- and static pre-allocation (using a simple escape analysis, and the static call graph respectively) and unboxing. Further, it generates polymorphic inline caches or virtual calls when a singleton type set cannot be deduced. Single-level class duplication is imprecise, because it only duplicates class types once for each allocation site, and allocation sites may be duplicated during analysis (as CPA possibly creates many templates for each function.) Extending it to N levels, or NCFA, would make the analysis terribly exponential and still not precise for deep polymorphism. For the summer of code, my main goal will be to efficiently and precisely handle data polymorphism up to arbitrary depths. I am currently looking into an iterative technique developed by John Plevyak. (Tiejun & Wang's technique is incomprehensible, and I don't see how the method used in Starkiller would work.) My other large goal will be to generate generics of appreciable complexity, based on the inferred types, i.e. to determine whether types may be uniformly parameterized, and to generate class and function templates. Finally, I will integrate an existing C++ garbage collector into the run-time system in order to clean up objects that could not be stack- or statically pre-allocated. Mentors: Jeremy Hylton, Brett Cannon = Mailbox modification = (Gregory K. Johnson) I intend to rewrite the Python library's mailbox module to support mailbox modification. I will extend the module's API (e.g., mailboxes will sport dictionary-like mapping) and enhance certain existing functionality (e.g., message objects will maintain mailbox-format-specific attributes). Full backward compatibility will be maintained. Mentor: Andrew Kuchling = Memory Profiler = (Nick Smallbone) I would like to apply to work over the summer on a Python memory profiler, as listed at CodingProjectIdeas. To see how much work is involved in this, I've put together a prototype, which tries to enumerate all objects from a root, calculating the size of each object it finds. Mentors: Michael Hudson, Jeremy Hylton = Python Bayesian Network Toolbox = (Elliot Cohen) Understanding about Bayesian Belief Networks and use of them is becoming more and more widespread. As understanding develops and spreads out of the research community, there is greater and greater need for a simple to use efficient open source Bayesian Network Toolbox. Bayesian Networks have been used to study a wide array of different areas including, ecological systems, medical diagnoses and financial modeling, among others. Currently, tools to define and use Bayesian Networks are limited to expensive closed source libraries or open source libraries designed for too specific a domain. One package that does support many varieties of Bayesian Networks is Kevin Murphy's Full BNT, which supports both discrete and continuous probability distributions in static and dynamic Bayesian Networks. Mentor: James Tauber = asyncIO = (Vladimir Sukhoy) The proposed goal is to bring cross-platform proactive I/O capabilities to Python. That will enable whole new style of application development with Python in cases when I/O is a bottleneck. Mentor: Mark Hammond = Interactive Python Notebook = (Toni Alatalo) See [http://ipython.scipy.org/google_soc/ipnb_google_soc.pdf]. Mentor: Fernando Perez = Porting _sre.c and arraymodule.c to Python = (Niklaus Haldimann, Blog: http://ubique.ch/soc) I would like to create a port of the standard library modules "_sre" and "array" to pure Python. This will benefit alternative Python implementations like PyPy, Jython and IronPython. These projects all have to provide their own implementations of standard library modules written in C if they're not available in pure Python. Mentors: Armin Rigo, Samuele Pedroni = Profile Replacement = (Floris Bruynooghe http://bruynooghe.blogspot.com) [Original idea from ProfileReplacementProject page.] The current profiler is not free according to the Debian Free Software Guidelines (http://bugs.debian.org/293932) and has been taken out of the main Debian distribution. This affects many users as the profiler is integrated into other programs such as ipython who lose functionality withouth the profiling available. The aim is to write a wrapper for hotshot that will act as a drop in replacement for the profile module. hotshot was chosen as base since it is much better tested then any newly written code would be. Secondly an independed stats module will be written for hotshot so that loading of the data will be much faster. This module will then also have a 100% pstats compatible wrapper. When this all gets completed and time is left over one of the things to investigate is weather it is possible to make hotshot thread aware. Mentor: Brett Cannon = Wax = (Jason Gedge) This project consists of updating the Wax library for Python. Code will be updated, or even added, to further develop the Wax library. Also, a primary focus will be that of documentation, which Wax currently lacks. Mentors: Hans Nowak = Data Serving/Collection Framework in Python/WSGI = Ho Chun Wei, blog: http://cwho.blogspot.com/ A framework based on bulk data serving/collection via the internet. Bulk data are in the form of files that could easily be several hundred MB (not surveys or simple POST data). The client has a file repository that it wishes to sync to the server (a WSGI application). This server should be able to facilitate transfer via a number of protocols, including HTTP file transfer, HTTP form upload, FTP, Email. This project is aimed not at yet another ad-hoc file transfer or p2p file-sharing program but as a persistent production setup for transferring data from data collection sites/areas to a server, possibly via internet through different methods to get through strict organizational firewalls and web admins. Mentors: Ian Bicking = A Mathematica-like Notebook GUI for IPython = (Tzanko Matev) I propose to write a GUI for IPython resembling the interfaces of the computer algebra applications Mathematica and Maple. Mentor: Fernando Perez = PythonModulePackaging = (Vincenzo Di Massa) '''(an ubuntu python SoC project)''' See: http://udu.wiki.ubuntu.com/PythonModulePackaging Create a mechanism for fully automated packaging of python modules based on an upstream release. Support different Python implementations and different versions of CPython (needed, when not all software can run with the latest/default python version when an Ubuntu release is going to happen).
