[ANN] IronPython Community Edition r4

Discussion in 'Python' started by Sanghyeon Seo, Nov 20, 2006.

  1. This is the fourth release of IronPython Community Edition (IPCE).

    You can download it from SourceForge.
    http://sourceforge.net/projects/fepy

    FePy project aims to provide enhancements and add-ons for IronPython.
    Visit the project's homepage for more informations.
    http://fepy.sourceforge.net/

    Changes in this release follow. Some changes are credited. Uncredited
    changes are from me.

    Regular expression

    _sre.py from PyPy, a pure Python implementation of Python's regular
    expression, is included and enabled by default, overriding
    IronPython's implementation based on System.Text.RegularExpression.
    You can comment out "install_sre_py()" line from site.py to disable
    this.

    Library

    Block encryption algorithms wrappers compatible with pycrypto are added.
    New array module based on codes from PyPy, but using .NET array as storage.
    pyexpat module is enhanced to run SOAPpy.
    pyexpat module handls multiple calls to Parse(). (Fredrik Lundh)
    hashlib module accepts arrays as arguments.
    ctypes module includes correct c_float and c_double.
    ctypes module handles functions taking variable argument list (like printf).
    site module initializes support for .pth files and site-packages
    directory. (Mark Rees)
    Missing built-in codec error handling callbacks are taken from PyPy
    and registered. Namely, ignore, xmlcharrefreplace, backslashreplace.
    (Christopher Baus)
    _fileobject class is taken from CPython and included in socket module.
    (Christopher Baus)

    WSGI

    WSGI gateway is rewritten to use wsgiref library and is a lot more
    compatible as a result. (Mark Rees)
    C# side of WSGI avoids creating new IronPython engine every request. (Mark Rees)
    C# side of WSGI gains various options configurable from web.config,
    including whether to reload IronPython engine every request.
    (Christopher Baus)

    Bundles

    url2path modules are now included from Python Standard Library. (Liyu Liu)
    wsgiref package is included from CPython 2.5, as needed by new WSGI gateway.
    pycrypto and paramiko are included. (paramiko doesn't work yet,
    although it imports.)

    Interesting--how does this fare, performance-wise?
