PyPy - Overview over the EU-reports

Below reports summarize and discuss research and development results of the PyPy project during the EU funding period (Dez 2004 - March 2007). They also are very good documentation if you'd like to know in more detail about motivation and implementation of the various parts and aspects of PyPy. Feel free to send questions or comments to pypy-dev, the development list.

Reports of 2007

The PyPy EU Final Activity Report summarizes the 28 month EU project period (Dec 2004-March 2007) on technical, scientific and community levels. You do not need prior knowledge about PyPy but some technical knowledge about computer language implementations is helpful. The report contains reflections and recommendations which might be interesting for other project aiming at funded Open Source research. (2007-05-11)

D09.1 Constraint Solving and Semantic Web is a report about PyPy's logic programming and constraint solving features, as well as the work going on to tie semantic web technologies and PyPy together. (2007-05-11)

D14.4 PyPy-1.0 Milestone report (for language developers and researchers) summarizes research & technical results of the PyPy-1.0 release and discusses related development process and community aspects. (2007-05-01)

D08.2 JIT Compiler Architecture is a report about the Architecture and working of our JIT compiler generator. (2007-05-01)

D08.1 JIT Compiler Release reports on our successfully including a JIT compiler for Python and the novel framework we used to automatically generate it in PyPy 1.0. (2007-04-30)

D06.1 Core Object Optimization Results documents the optimizations we implemented in the interpreter and object space: dictionary implementations, method call optimizations, etc. The report is still not final so we are very interested in any feedback (2007-04-04)

D14.5 Documentation of the development process documents PyPy's sprint-driven development process and puts it into the context of agile methodologies. (2007-03-30)

D13.1 Integration and Configuration is a report about our build and configuration toolchain as well as the planned Debian packages. It also describes the work done to integrate the results of other workpackages into the rest of the project. (2007-03-30)

D02.2 Release Scheme lists PyPy's six public releases and explains the release structure, tools, directories and policies for performing PyPy releases. (2007-03-30)

D01.2-4 Project Organization is a report about the management activities within the PyPy project and PyPy development process. (2007-03-28)

D02.3 Testing Tool is a report about the py.test testing tool which is part of the py-lib. (2007-03-23)

D10.1 Aspect-Oriented, Design-by-Contract Programming and RPython static checking is a report about the aop module providing an Aspect Oriented Programming mechanism for PyPy, and how this can be leveraged to implement a Design-by-Contract module. It also introduces RPylint static type checker for RPython code. (2007-03-22)

D12.1 High-Level-Backends and Feature Prototypes is a report about our high-level backends and our several validation prototypes: an information flow security prototype, a distribution prototype and a persistence proof-of-concept. (2007-03-22)

D03.1 Extension Compiler is a report about PyPy's extension compiler and RCTypes, as well as the effort to keep up with CPython's changes. (2007-03-21)

D07.1 Massive Parallelism and Translation Aspects is a report about PyPy's optimization efforts, garbage collectors and massive parallelism (stackless) features. This report refers to the paper PyPy's approach to virtual machine construction. (2007-02-28)

Reports of 2006

D14.3 Report about Milestone/Phase 2 is the final report about the second phase of the EU project, summarizing and detailing technical, research, dissemination and community aspects. Feedback is very welcome!

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
