Hello,

It looks that the issue with fetch across rollback still can occur in the new version. It turned up when I applied the Pysqlite transaction test suite to some dbapi2 version of my own. Below is a minimal script to reproduce it. It has puzzled me what goes wrong and I would like to believe that the old version is still installed. But the printed version is the new one. Also it behavious slightly different, as the same result comes also after commit. In 2.5.1 you would not get that far. The issue is not causing practical problems but it would be nice to have a work-around to get a clean test result.
It is great, by the way, that commit and rollback are now dealing equally with open cursors!

cur.execute ('select 1 union select 2 union select 3')
con.rollback ()
print cur.fetchall ()
