RHBA-2011:0284 - python bug fix update

Synopsis

python bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated python packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl, Scheme, or Java. Python includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems such as X11, Motif, Tk, Mac, and MFC.

This update fixes the following bugs:

• Prior to this update, Python programs that used "ulimit -n" to enable communication with large numbers of subprocesses could still monitor only 1024 file descriptors at a time, which caused an exception:

  ValueError: filedescriptor out of range in select()

This was due to the subprocess module using the "select" system call. The module now uses the "poll" system call, removing this limitation. (BZ#668975)

• Due to the urllib2 module ignoring the "no_proxy" environment variable for the FTP scheme, programs such as Yum could erroneously access a proxy server for ftp:// URLs covered by a "no_proxy" exclusion. With this update, a patch has been applied to address this issue, and "no_proxy" is no longer ignored. (BZ#671343)

All users of python are advised to upgrade to these updated packages, which resolve these issues.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
