Package: python-psycopg2 Version: 2.0.7-4 Severity: important Tags: patch I am currently working on migrating a software project from psycopg1 to psycogp2, based on the recommendations of the psycopg developers.
Some of the Python-based daemons in our software package will severely crash with a glibc error when using psycopg 2.0.7. I'm attaching the stderr output of the process. It appears that the low-level code crashes as the program tries to send a packet to a PostgreSQL connection that has been lost. This bug appears to have been fixed upstream about a month after the 2.0.7 release. I tried backporting 2.0.10, and our software now runs without crashing. Still, our software will be unusable on Debian Lenny without running a backported psycopg2 package. This appears to be the upstream patch that fixes the problem (although I have not tested applying it in isolation to the 2.0.7 codebase):
