Bug Fix Advisory python-psycopg2 bug fix and enhancement update

Advisory: RHBA-2013:0327-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2013-02-20
Last updated on: 2013-02-20
Affected Products: Red Hat Enterprise Linux HPC Node (v. 6)
Red Hat Enterprise Linux Server (v. 6)
Red Hat Enterprise Linux Workstation (v. 6)

Details

Updated python-psycopg2 packages that fix multiple bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

The python-psycopg2 packages provide a PostgreSQL database adapter for the
Python programming language (like pygresql and popy). The main advantages of
psycopg2 are that it supports the full Python DBAPI-2.0 and that it is thread
safe at level 2.

The python-psycopg2 packages have been upgraded to upstream version 2.0.14,
which provides a number of bug fixes and enhancements over the previous version,
including the fix for a memory leak in cursor handling. This update also ensures
better compatibility with the PostgreSQL object-relational database management
system version 8.4. (BZ#765998)

This update also fixes the following bugs:

* Prior to this update, a copy operation terminated unexpectedly if a second
thread in a single application triggered the Python garbage collection while the
copy operation was in progress. This update adds the appropriate object
reference count adjustments to the code. (BZ#711095)

* Prior to this update, object reference counting could, under certain
circumstances, cause assertion failures in Python. This update modifies the
underlying code to avoid these failures. (BZ#843723)

All users of psycopg2 are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements.
