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.
Building without extensions has been long broken and nobody really cares
about a pure-DBAPI implementation (which could be created using a wrapper
instead).
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.
- Check return value of PyErr_Malloc and set an exception in case of error
- Avoid exposing variables with refcount 0 as connection attributes.
- PyErr_Free guards itself for NULL input
.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.
Dropped set/unset nonblocking mode for copy and lobject operations:
lobjects don't work in nonblocking mode so they will hardly be supported
in green/async branches. Support for copy is still feasible, but it
will be done in other code paths (called by poll).
The function is called without holding the GIL. Because it is necessary
to execute the Python callback if set, we need to re-acquire the GIL and
tnen release it again. In order to correctly bookkeep the thread state,
the pointer of the _save variable is passed to the function.
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.
including behaviour on closed lobjects and stale lobjects.
* psycopg/lobject_type.c (psyco_lobj_close): don't mark the
connection closed here because it is done by
lobject_close_locked().
* psycopg/lobject_int.c (lobject_open): mark objects as not closed
if we successfully open them.
(lobject_close_locked): mark the lobject closed here.
(lobject_export): ensure we are in a transaction, since
lo_export() issues multiple queries.
* psycopg/lobject_type.c (lobject_setup): make lobjects start closed.
