I am running Ubuntu 10.04, python 2.6.5, SA 0.6.6, latest pyodbc
release. I have tried FreeTDS that ships with the distro (0.82) as
well as current CVS. I can make a connection and issue a basic SQL
statement. However, when I try to run my unit tests, I get the
following error:
*** glibc detected *** /path/to/venv/bin/python: free(): invalid next
size (fast): 0x02527bf0 ***
nothing ive seen before with freetds (and I use freetds a lot) - so your steps
would be to isolate the problem into something reproducible, then ask on the
FreeTDS or possibly pyodbc lists, possibly first converting it into a straight
pyodbc script so there are at least fewer layers of abstraction at play.
The SQL issued just before that error is:
2011-04-07 00:26:39,257 INFO sqlalchemy.engine.base.Engine.0x...0350
INSERT INTO corporate_sessions (createdts, updatedts, id, hits,
relatedip, user_id) VALUES (?, ?, ?, ?, ?, ?)
2011-04-07 00:26:39,257 INFO sqlalchemy.engine.base.Engine.0x...0350
(datetime.datetime(2011, 4, 7, 0, 26, 39, 257073), None,
u'e1457896AdZgRjqg8CD8', 0, '10.66.3.230', 1)
and then the process just hangs and I have to kill the process.
My unit tests run successfully against sqlite, postgresql, and MSSQL
on Windows. I have successfully ran the following test script on with
the same libraries and virtualenv:
import datetime
import sqlalchemy as sa
eng = sa.create_engine(mssql://user:pass@server/temp?
Port=1435TDS_Version=8.0,echo=True)
res = eng.execute('select 1+1 as foo')
for row in res:
print 'answer=',row['foo']
#eng.execute('DROP TABLE satest')
#eng.execute('CREATE TABLE satest(id INT, name VARCHAR(300), ts
datetime)')
res = eng.execute('INSERT INTO satest(id, name, ts) VALUES (?, ?, ?)',
(10, u'foobar', datetime.datetime(2011, 4, 7, 0, 26,
39, 257073)))
One last thing, when I first tested this, I got an error related to
using an ORM instance when it had already been deleted (or something
like that, I can't remember exactly). But I haven't seen that error
for a long time and don't remember doing anything in particular to
change it.
