The type 'long' with Windows Visual C is 32bits in size for both 32bit and 64bit platforms. Changed type of variables that could be > 2GB from long to Py_ssize_t.
Don't issue a SET TRANSACTION ISOLATION LEVEL at every begin: use PG's
GUC default, eventually set by set_transaction.
Dropped the last query at connection, yay!
Method set_isolation_level() and property isolation_level refactored using
the new structures, keeping the previous semantic.
It has long been used in wrong ways, with the function receiving a
connection or lobject instead of a cursor. It has always been unnoticed
(nobody has noticed the wrong object attached to the exception in the
wrong cases) but it started crashing the interpreter with Python 3.2 on
Windows.
Thanks to Jason Erickson for finding the problem and helping fixing it.
.c files only need to import psycopg.h: it will in turn import
dependencies from Python and libpq and configure.h. psycopg.h should be
the first to be imported, so the basic imports are not required in
the .h's
As a guideline I'm trying to import from the most specific to the most
generic to detect missing imports in the .h's.
The lobject.truncate(len=0) method will be available if psycopg2 has
been built against libpq from 8.3 or later (which is when the lobject
truncating support has been introduced).
and change the Python level attribute to a getset.
* psycopg/lobject.h (lobjectObject): remove the closed member,
since "fd < 0" gives us the same information. Reorder the struct
members for better packing.
