RHBA-2009:1508 - Bug Fix Advisory

Topic

An updated pexpect package that fixes two bugs is now available.

Description

pexpect is a pure Python module for spawning child applications,
controlling them, and responding to expected patterns in their output.
Pexpect works like Don Libes' Expect. Pexpect allows your script to spawn a
child application and control it as if a human were typing commands.
Pexpect can be used for automating interactive applications such as ssh,
ftp, passwd, telnet, etc. It can also be used to automate setup scripts for
duplicating software package installations on different servers and for
automated software testing.

This update addresses the following issues:

• pexpect was previously included in the unsupported Extra Packages for

Enterprise Linux (EPEL) repository. It is now a supported package in Red
Hat Enterprise Linux but is otherwise unchanged. The initial release of
pexpect as a supported package included no changes at all and, as a
consequence, did not obsolete the EPEL version. To ensure the supported
package properly obsoletes the EPEL package, the Release value for this
package was incremented. (BZ#481380)

• previously, the shebang lines in pexpect's python executables pointed to

"/usr/bin/env python" rather than explicitly referencing the version of
Python installed on the system. This broke these executables in the case of
a user installing an alternative Python version. With this update, all
shebang lines point explicitly to the system version at /usr/bin/python.
(BZ#521891)

All pexpect users should install this updated package, which addresses
these issues.

Solution

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