	leak on None as suggested by gh (closes: #16).

2005-05-10  Federico Di Gregorio  <fog@debian.org>

	* lib/extras.py (DictRow): we now save a reference to the index
	itself and not to the cursor to avoid problems while accessing
	DictRow objects after reusing the cursor for a different query
	(using  Kevin Jacobs db_row would be much better but DictRow is
	just an example, right?)

	passed string length.

	* psycopg/typecast.c (typecast_cast): set curs->caster to self
	during the type-casting.

	* psycopg/cursor_type.c: added "typecaster" attribute to the
	cursor (this is safe, cursors can't be shared among threads and
	the attribute is RO.)

2005-03-22  Federico Di Gregorio  <fog@debian.org>

	* psycopg/typecast_array.c: added some more structure to implement
	array typecasting.

	* scripts/buildtypes.py: new version to include array data.

2005-03-15  Federico Di Gregorio  <fog@debian.org>

	* lib/extensions.py: Added AsIs import.

	* Release 1.99.13.

	* psycopg/cursor_type.c (psyco_curs_executemany): implemented as a
	wrapper to extract python arguments and then call
	_psyco_curs_execute().

	python argument parsing from the real execute code, to later allow
	for .executemany().

	* psycopg/typecast.c (typecast_call/typecast_cast): modified

2005-03-04  Federico Di Gregorio  <fog@initd.org>

	* Release 1.99.12.1.

	* psycopg/adapter_asis.c (asis_str): changed call to PyObject_Repr

	* Release 1.99.12.
	
	* psycopg/adapter_*.c: added __conform__ to all adapters.
	
	* psycopg/adapter_qstring.c (qstring_quote): we now use

	* psycopg/pqpath.c (_pq_copy_out_v3): implemented and working.

	* psycopg/cursor_type.c (psyco_curs_copy_to): added cursor object
	interface for copy_to.

	* COPY FROM implemented using both old and new (v3) protocol.

	* psycopg/config.h (Dprintf): declaration for asprintf is gone.

	* psycopg/pqpath.c (_pq_copy_in_v3): implemented.

2005-03-01  Federico Di Gregorio  <fog@debian.org>

	* setup.py: now we generate a slighly more verbose version string
	that embeds some of the compile options, to facilitate users' bug
	reports.

	* psycopg/cursor_type.c (psyco_curs_copy_from): we now use
	PyOS_snprintf instead of asprintf. On some platforms this can be
	bad (win32).. if that's your case, get a better platform. :/

	typo that made adaptation using __conform__ impossible.

2005-02-28  Federico Di Gregorio  <fog@debian.org>

	* lib/extras.py: removed AsIs adapter (now a built-in); also
	removed prepare() method from the adapters that don't use it to
	avoid an extra method call at mogrification time.

	* psycopg/psycopgmodule.c (psyco_adapters_init): added
	initialization of the AsIs adapter (adapts int, long, float and
	*wonder* None!)

	* psycopg/cursor_type.c (_mogrify_getquoted): reorganized the code
	to adapt and then call .getquoted() to obtain the quoted data into
	this new function.

2005-2-27  Federico Di Gregorio  <fog@initd.org>

2005-01-29  Federico Di Gregorio  <fog@debian.org>

	* psycopg/pqpath.c (_pq_fetch_tuples): fixed scale-related
	segfault (*fourth* mail from Andrea. Another couple like this and
	psycopg 2 will exit alpha at warp speed.)
	
	* psycopg/pqpath.c (pq_fetch): _pq_copy_out_3 -> _pq_copy_out_v3
	(second and third mail from Andrea. :/)

	on .write() attribute, fixed compilation problems (first mail from
	Andrea Arcangeli.)

2005-01-20  Federico Di Gregorio  <fog@debian.org>

	* lib/extensions.py (register_adapter): added register_adapter
	function, exported ISQLQuote in psycopg.extensions.

	pq_fetch in syncronous DBAPI compatibility mode to solve rowcount
	problem.

2004-12-14  Federico Di Gregorio  <fog@debian.org>

	* Mm.. release 1.99.11.

	* psycopg/cursor_type.c (_psyco_curs_prefetch): fixed bug in
	interaction between the .isready() method and
	_psyco_curs_prefetch: isready now store away the pgres but leave
	prefetch do its work.

	* psycopg/*.c: changed the names of most of the psycopg's built-in
	types to replect their position in the psycopg._psycopg module.

2004-12-10  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c: now *all* write or async accesses to the
	connection object are arbitrated using the connection lock.
	
	* psycopg/cursor_type.c (psyco_curs_isready): now we reset the
	current async cursor if it is ready, to allow other cursors to
	.execute() without raising the "transaction in progress" error.

	* psycopg/pqpath.c (pq_is_busy): gained status of high-level
	function with its own blocking and locking.

	* psycopg/cursor.h (EXC_IF_CURS_CLOSED): also checks the
	connection (a closed connection implies a closed cursor.)

	* psycopg/cursor_type.c: cursor's connection is correctly
	INCREFfed and DECREFfed.

	* psycopg/connection_type.c: removed the cursors list from the
	connection object. It is not necessary anymore for the connection
	to know about the cursors and the reference counting will keep the
	connection alive (but possibly closed) until all cursors are
	garbage collected.

2004-11-20  Federico Di Gregorio  <fog@initd.org>

	* psycopg/cursor_type.c (_mogrify): ported %% fix from 1.1.15.

	argument to 'cursor_factory'.

2004-11-19  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (_psyco_curs_buildrow_fill): now standard
	tuples are filled using PyTuple_SET_ITEM while extended types
	(created via row_factory) are filled using PySequence_SetItem.
	
	* psycopg/cursor_type.c: changed cursor attribute name from
	tuple_factory to row_factory.

2004-10-14  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (_psyco_curs_buildrow_fill): now we use
	PySequence_SetItem to avoid problems with containers created from
	cursor's .tuple_factory attribute.

	* lib/extras.py (DictCursor.execute): fixed stupid bug with cursor
	setting self.tuplefactory instead of self.tuple_factory.

	* Release 1.99.10.
	
	* psycopg/cursor_type.c (_psyco_curs_buildrow_*): unified normal
	and factory code into the _psyco_curs_buildrow_fill function; no
	more memory leaks here. 

	* psycopg/config.h (round): added check for __FreeBSD__ (that
	should be defined when compiling with gcc, I hope.)

	* setup.py: removed a lot of code now in setup.cfg.

2004-09-24  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (cursor_dealloc): fixed small memory leak
	due to missing disposal of self->pgres.

	Volonghi.

2004-09-14  Federico Di Gregorio  <fog@debian.org>

	* psycopg/microprotocols.c (microprotocols_adapt): lots of changes
	to the microprotocols layer (it is not micro anymore);
	implementing almost all the PEP 246. The adapter registry is now
	indexed by (type, protocol) and not by type alone.

2004-09-13  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (_mogrify): and qattr is gone.

2004-09-05  Federico Di Gregorio  <fog@debian.org>

	* Release 1.99.9 (or, the "twisting by the pool" release).

	* psycopg/pqpath.c (_pq_fetch_tuples): changed to "static void"
	instead of "static int", no ways for this function to fail.

2004-09-04  Federico Di Gregorio  <fog@debian.org>

	* examples/encoding.py: much better encoding example, also using
	the new UNICODE typecaster.

	* psycopg/typecast_basic.c (typecast_UNICODE_cast): added UNICODE
	typecaster.

	* lib/extensions.py: the encodings dictionary is not available by
	default but can be accessed from the psycopg.extensions module.

	qstring adapter and moved it into psycopg module.

2004-08-26  Federico Di Gregorio  <fog@debian.org>

	using strings instead of buffers when converting postgresql binary
	objects (should *temporarily* fix corruption bug reported on
	win32.)

2004-07-21  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c: removed __iter__ and next methods from
	object methods and moved them where they do belong (tp_iter and
	tp_iternext.) Bug reported by Daniele Varrazzo (again!)

2004-07-19  Federico Di Gregorio  <fog@debian.org>

	* psycopg/typecast_datetime.c (typecast_PYINTERVAL_cast): replaced

	added extension methods related to async queries. 

2004-07-15  Federico Di Gregorio  <fog@debian.org>

	through the cursor members interface. that's all folks.

	* lib/extensions.py: added extensions module to clearly separate
	psycopg own extensions from DBAPI-2.0

2004-07-10  Federico Di Gregorio  <fog@debian.org>

2004-04-18  Federico Di Gregorio  <fog@debian.org>

	* Applied changes from Jason Erickson to build on win32; see his
	(slightly edited) entry below. (Still builds on Linux :)

	* psycopg/*.c: removed inclusion of pthread.h from all files
	except psycopg/config.h to build on win32 without faking the file.

2004-04-15  Jason Erickson <jerickso@stickpeople.com>
 
        * setup.py: Various changes. The critical ones: 
	  - Make an empty pthread.h file so all the code doing an 
	    #include <pthread.h> will find something.
	  - Appended the winsock2 library and the PostgreSQL library to 
	    the library path.
	  - Setup the include path.
	  - Have the PSYCOPG_VERSION macro be included with quotes.
 
        * config.h: Added/Cleaned up Win32 includes, defines, stub functions.
 
        * typecast.h: Removed ';' after PyObject_HEAD in the
	typecastObject structure since Microsoft Visual Studio does not
	like it.

2004-04-15  Federico Di Gregorio  <fog@debian.org>

	* Release 1.99.5 (bug-fixing and reorganization)

	* setup.py et al.: moved psycopg to psycopg._psycopg to make

	default).

	* psycopg/typecast.h: removed aliases, they now live in the right
	typecast_xxx.c file.

2004-03-08  Federico Di Gregorio  <fog@debian.org>

	* Release 1.99.3 (alpha 4).

	* examples/lastrowid.py: and the .lastrowid example is in.

2004-03-01  Federico Di Gregorio  <fog@debian.org>

	* psycopg/connection_int.c (conn_close): does not use libpq
