- fixes various memory leaks found by valgrind and a follup closer
code inspection of the bsddb module. (merges r1.32 of _bsddb.c
and an associated test case)
- also merges the one line r1.37 _bsddb.c fix that fixes a leak on
the rare DBEnv creation failed error path.
the python 2.3.x branch as the bsddb.set_get_returns_none() default
behaviour is different than on 2.4 and leter. (yes a correct test
case for this branch could be written; removing this bad test gets
things not-failing fastest)
* Fixed a bug in the compatibility interface set_location() method
where it would not properly search to the next nearest key when
used on BTree databases. [SF bug id 788421]
* Fixed a bug in the compatibility interface set_location() method
where it could crash when looking up keys in a hash or recno
format database due to an incorrect free().
* Extended DB & DBEnv set_get_returns_none functionality to take a
"level" instead of a boolean flag. The boolean 0 and 1 values still
have the same effect. A value of 2 extends the "return None instead
of raising an exception" behaviour to the DBCursor set methods.
This will become the default behaviour in pybsddb 4.2.
* Fixed a typo in DBCursor.join_item method that made it crash instead
of returning a value. Obviously nobody uses it. Wrote a test case
for join and join_item.
underlying DB has already been closed (and thus all of its cursors).
This fixes a potential segfault.
SF pybsddb bug id 667343
bugfix: close the DB object when raising an exception due to an error
during DB.open. This prevents an exception when closing the
environment about not all databases being closed.
