SIGs/Python

Python Special Interest Group

A SIG for people who are interested in Python on Fedora. This includes:

• packaging and optimizing the various Python 2 and Python 3 Python runtimes
• packaging Python libraries and applications
• setting and improving standards for packaging them as RPMs
• maintaining Python packages for Fedora

Python packages awaiting review

• List of most python packages awaiting review - Bugzilla query for packages which have not passed review with "python" in the name or summary.

• pynie - Python 3, on top of the Parrot virtual machine

Package requests

• Chandler PIM
• itools - A python library that includes several useful tools, such as an ODF anonymizer that can be used to sanitize confidential documents before attaching them tp bug reports
• python-multiprocessing - multiprocessing backport useful for EL-5 review request

Python Features

Under development (Fedora 17?)

• port anaconda and yum to python 3
• debug versions of Python 2 and Python 3 in addition to the traditional optimized builds
• add PyPy to Fedora, possibly with a stack of extensions
• add a stack of extensions to Jython, in RPM form
• upgrade of the Python 3 stack to 3.3

Under development (Fedora 16?)

• GCC plugin embedding Python, for writing GCC extensions in Python
• Static analysis tool to detect common mistakes made in Python extension modules written in C

Added in Fedora 15

• upgrade of the Python 3 stack to 3.2

Added in Fedora 14

• upgrade of the Python 2 stack to 2.7
• pypy was packaged, available prebuilt via rpm

Added in Fedora 13

• parallel-installable Python 3 stack
• gdb hooks to make it easier to debug Python and extension modules
• Systemtap probe points for tracing Python function calls

Added in Fedora 11

• upgrade of the Python 2 stack to 2.6

Added in Fedora 10

• created and packaged bindings for the FIPS-validated NSS cryptographic library

Python Runtimes

Within Fedora:

• python - The standard "CPython" implementation of Python 2
• python3 - As above, for Python 3. There's a separate page detailing the status of building up a stack of pre-packaged Python 3 modules
• jython - Python 2 implementation on top of the Java virtual machine
• pypy - An alternate python 2 interpreter (with a JIT-compiler) written in a subset of python, compiled to .c. The interpreter has better memory use than CPython and speed is closing in on CPython. The JIT'd version is faster than CPython in many benchmarks. It is growing the ability to load CPython extension modules, though this is in an "alpha" state right now.

Within EPEL:

• python26 - Python 2.6 stack for EPEL5, parallel-installable with the system Python 2.4 stack

Awaiting review:

• pynie - Python 3, on top of the Parrot virtual machine

Awaiting packaging

• IronPython
  • Ironclad CPython extensions from IronPython
• Python-on-a-Chip (p14p)

Python Compilers

Within Fedora:

• pyjamas - Python-to-JavaScript compiler, implemented in Python
• shedskin - Python to C++ compiler (for a subset of Python with "implicit types")
