tl;dr
This segfault only affects the psycopg wheel package: the workaround is to build psycopg from source, e.g. using:
$ pip install --no-binary psycopg2
or the entry in the requirements.txt file:
psycopg2>=2.7,<2.8 --no-binary psycopg2
Running the delete_database function in this snippet against our database causes a segmentation fault in psycopg2==2.7 and 2.7.1, but not in 2.6.2. The segmentation fault seems to happen inside OpenSSL.
Debugging revealed that SSL_library_init is being called twice, once by the Python ssl module and once by the libpq library that comes with psycopg2, where it segfaults. Not sure if this function is allowed to be called twice or not.
import contextlib
import psycopg2
from fabfile.lib import info, parse_uri
@contextlib.contextmanager
def create_connection(connection_uri):
connection_args = parse_uri(connection_uri)
conn = psycopg2.connect(
database='postgres', user=connection_args.username,
password=connection_args.password, host=connection_args.hostname,
port=connection_args.port if connection_args.port else 5432)
conn.set_isolation_level(0)
yield conn.cursor()
conn.close()
def delete_database(connection_uri, database):
hostname = parse_uri(connection_uri).hostname
info('deleting database {} on {}'.format(database, hostname))
with create_connection(connection_uri) as cur:
cur.execute('''SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = %s
AND pid <> pg_backend_pid()''', (database, ))
cur.execute('DROP DATABASE "{}"'.format(database))
The system openssl is 1.0.1f-1ubuntu2.22 on Ubuntu 14.04.
On psycopg2==2.6.2 this works fine.
On psycopg2==2.7 we get the following segmentation fault:
Program received signal SIGSEGV, Segmentation fault.
