I'm trying to solve a RedHat Enterprise Linux 4 issue where I have
built, from source, Python 2.5.2, mod_python v3.2.8, and SQLite 3.5.9.
SQLite works fine in the Python 2.5.2 interpreter, but when running from
mod_python (I also tried mod_wsgi), I get a segmentation fault in the
Python file Objects/dictobject.c:571 when running a query.
I would like to try SQLite version 3.4.2 to get to a known setup just to
verify the problem isn't being caused elsewhere.
Any ideas are welcome.
----------------
Python test code
----------------
"""\
This program verifies that mod_python is able to use the SQLite module
integrated into
Python.
"""
import sqlite3
from mod_python import apache
def handler(req):
req.content_type = 'text/plain'
req.send_http_header()
# query SQLite3
req.write('Opening database connection ')
con = sqlite3.connect('/rh241/u01/TestWsgiPylons/test.db')
req.write('[OK]\r\nQuerying database ')
# ****THIS CAUSES A SEGMENTATION FAULT (see GDB snippet below)****
cur = con.execute('select * from test')
req.write('[OK]\r\nFetching result set')
results = cur.fetchall()
req.write('[OK]\r\n')
req.write('Query results = ' + str(results) + '\n')
return apache.OK
----------
GDB Output
----------
Program received signal SIGSEGV, Segmentation fault.
