psycopg2/ChangeLog

2009-04-19  Federico Di Gregorio  <fog@initd.org>

	* psycopg/cursor_type.c: patch from Gangadharan to avoid double
	free of the cursor when the connection that creates it is closed
	implicitly by dealloc.

	* psycopg/connection_type.c: patch from Gangadharan to avoid double
	free of the connection object when calling close() implicitly.

	* psycopg/connection_type.c: patch from Marko Kreen to implement
	get_parameter_status().

	* psycopg/connection.*: exposed protocol_version and
	server_version attributes on the connection object.

	* lib/extras.py: patch from Marko Kreen to implement missing dict
	methods in DictRow.

2009-04-04  Federico Di Gregorio  <fog@initd.org>

	* connection_int.c(conn_notice_callback): removed all Python
	calls because conn_notice_callback() can be called without a lock
	on the GIL. Moved processing and cleanup of notices into their
	own functions that are called while holding the GIL.

2009-04-01  Federico Di Gregorio  <fog@initd.org>

	* Applied patch from Menno Smits to fix failures in test_dates
	when executed in older version of Python.

	* Applied patch from Menno Smits to fix lobject test failures.

2009-03-08  Federico Di Gregorio  <fog@initd.org>

	* microprotocols.c: None is always adapted to NULL to avoid
	errors when calling adapt on nested types without first checking
	for None.

2009-03-02  Federico Di Gregorio  <fog@initd.org>

	* Applied modified patch from Karsten Hilbert to provide a
	type-caster able to parse times with seconds in the time zone.

	* Applied patch from Menno Smits to avoid problems with DictCursor
	when the query is executed by a named cursor. Also added Menno's
	tests and uniformed other DictCursor tests.

	* psycopg/psycopgmodule.c: fixed unwanted exception when passing an
	explicit None to register_type().

	* psycopg/config.h: applied patch from Jason Erickson to build
	with MSVC. Solaris version of isinf() is now a macro.

2009-02-27  Federico Di Gregorio  <fog@initd.org>

	* psycopg/config.h: added check to provide compatible isinf()
	for Solaris (thanks to Jeremy Mason.)

2009-02-23  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.9.

2009-02-17  James Henstridge  <james@jamesh.id.au>

	* psycopg/utils.c (psycopg_escape_string): same here.

	* psycopg/adapter_binary.c (binary_escape): simplify PostgreSQL
	version check.

	* setup.py (psycopg_build_ext.finalize_options): use a single
	define of the PostgreSQL version in a form that can easily be used
	by #ifdefs.

	* tests/test_dates.py (DatetimeTests, mxDateTimeTests): full test
	coverage for datetime and time strings with and without time zone
	information.

	* psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): adjust
	to handle the changes in typecast_parse_time.
	(typecast_PYTIME_cast): add support for time zone aware time
	values.

	* psycopg/typecast_mxdatetime.c (typecast_MXDATE_cast): make sure
	that values with time zones are correctly processed (even though
	that means ignoring the time zone value).
	(typecast_MXTIME_cast): same here.

	* psycopg/typecast.c (typecast_parse_time): Update method to parse
	second resolution timezone offsets.

	* psycopg/typecast.c (typecast_parse_time): Fix up handling of
	negative timezone offsets with a non-zero minutes field.

	* tests/test_dates.py (DatetimeTests): Add tests for time zone
	parsing.  The test for HH:MM:SS time zones is disabled because we
	don't currently support it.

2009-02-16  Federico Di Gregorio  <fog@initd.org>

	* FreeBSD now has round(). Modified config.h as suggested by
	Jeroen Ruigrok van der Werven.

2009-02-06  Federico Di Gregorio  <fog@initd.org>

	* Applied patch by Markus Demleitner to make executemany() return
	the sum of modified rows by executed statements or -1 if any one
	statement returns it. This is still DBAPI-2.0 compliant.

2009-01-23  Federico Di Gregorio  <fog@initd.org>

	* Fixed problem mailed by Markus Demleitner about Python to
	PostgreSQL conversions of "nan" and "inf" floats resulting in
	backend errors. Added the new psycopg2.extensions.Float adapter
	that correctly handle both values and unit tests. (The opposite
	conversion was already working.)

2009-01-20  Federico Di Gregorio  <fog@initd.org>

	* Fixed problem reported by Lawrence Oluyede where
	register_type() didn't work on connection and cursors
	suclasses.

2009-01-10  Federico Di Gregorio  <fog@initd.org>

	* psycopg/cursor_type.c: cursor.isready() now raise an exception
	when the libpq PQconsumeInput() call fails.

2008-12-04  Federico Di Gregorio  <fog@initd.org>

	* psycopg/lobject_type.c: fixed memory leak. The patch was kindly
	sent from a psycopg user but I wrongly deleted the email so no
	kudos (and I had to fix the problem by myself!)

2008-11-25  Federico Di Gregorio  <fog@initd.org>

	* psycopg/cursor_type.c: integrated patch from Alejandro Dubrovsky.
	Note that the statically allocated buffer should probably go away
	in favor of always allocating the buffer dinamically.

	* psycopg/utils.c: modified patch from Alejandro Dubrovsky to
	support quoted separators in COPY queries: now all the string
	quoting code is in utils.c and the same function is used by
	qstrings and everything else (like the COPY code.)

2008-09-24  Federico Di Gregorio <fog@initd.org>

	* lib/extras.py: added inet support and related tests.

2008-09-23  James Henstridge  <james@jamesh.id.au>

	* psycopg/psycopg.h (NotSupportedError_doc): clean up
	spelling/grammar a bit, using exception description from the PEP.

2008-09-23  Federico Di Gregorio <fog@initd.org>

	* Applied patch from Brian Sutherland that fixes NULL
	valus in UUID support.

2008-09-19  Federico Di Gregorio <fog@initd.org>

	* lib/extras.py: added UUID support, modeled after the code
	sent by Brian Sutherland.

2008-09-16  Federico Di Gregorio <fog@initd.org>

	* Release 2.0.8.

2008-07-26  Federico Di Gregorio <fog@initd.org>

	* psycopg/connection_type.c: merged get_backend_pid() method
	by Casey Duncan.

2008-07-23  James Henstridge  <james@jamesh.id.au>

	* psycopg/lobject_type.c (lobject_setup): use
	FORMAT_CODE_PY_SSIZE_T in Dprintf() call for 64-bit compatibility
	when using Python 2.5 or later.
	(lobject_dealloc): same here.

2008-07-18  James Henstridge  <james@jamesh.id.au>

	* psycopg/adapter_qstring.c (qstring_traverse): add cyclic GC
	traversal for quoted string adapters.

	* psycopg/adapter_pboolean.c (pboolean_traverse): add cyclic GC
	traversal for boolean adapters.

	* psycopg/adapter_mxdatetime.c (mxdatetime_traverse): add cyclic
	GC traversal for mxdatetime adapters.

	* psycopg/adapter_datetime.c (pydatetime_traverse): add cyclic GC
	traversal for datetime adapters.

2008-07-01  James Henstridge  <james@jamesh.id.au>

	* psycopg/adapter_binary.c (binary_traverse): add cyclic GC
	traversal for binary adapters.

	* psycopg/adapter_asis.c (asis_traverse): add cyclic GC traversal
	for AsIs adapters.

	* psycopg/adapter_list.c (list_traverse): add cyclic GC traversal
	for list adapters.

2008-05-28  James Henstridge  <james@jamesh.id.au>

	* psycopg/cursor_type.c (cursor_setup): incref before setting
	attributes, to make things GC-safe.

	* psycopg/cursor_int.c (curs_reset): make clearing of description
	and casts attributes GC-safe.

	* psycopg/typecast.c (typecast_traverse): implement cyclic GC
	traversal for typecasters.

	* psycopg/connection_type.c:
	* psycopg/cursor_type.c: add support for cyclic GC traversal (no
	support for clearing).

	* psycopg/python.h: add definitions for Py_CLEAR() and Py_VISIT()
	for compatibility with old versions of Python.

2008-06-28  Federico Di Gregorio <fog@initd.org>

	* setup.py: fixed problem with spaces in pg_config path.

2008-05-27  Federico Di Gregorio <fog@initd.org>

	* psycopg/pqpath.c: better error checks in _pq_copy_in_v3 to
	avoid calling blocking libpq functions when the connection to
	the server has been broken

2008-05-19  Federico Di Gregorio <fog@initd.org>

	* psycopg/cursor_type.c: fixed memory leak in .executemany(); on
	error "iter" was not dec'reffed.

2008-05-06  James Henstridge  <james@jamesh.id.au>

	* psycopg/lobject.h (lobjectObject): remove "mode" struct member,
	since it was unused.

	* psycopg/lobject_*.c: replace uses of the closed struct member,
	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.

	* psycopg/lobject*: const'ify the code.

	* tests/test_lobject.py (LargeObjectTests): add more tests,
	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.

2008-05-05  James Henstridge  <james@jamesh.id.au>

	* psycopg/lobject.h: don't export the lobjectType symbol.

2008-05-05  Federico Di Gregorio  <fog@initd.org>

	* Fixed sun build problem by adding "sun" to config.h checks.

2008-05-05  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (pq_complete_error): get rid of double free
	error in case when pgres is NULL.

	* tests/test_lobject.py: add some basic tests for large object
	code.

	* psycopg/lobject*.[ch]: port the large object code to work with
	current psycopg code.

2006-09-01  Federico Di Gregorio  <fog@initd.org>

	* psycopg/connection_type.c: merged in double mutex destroy patch
	from Joerg Sonnenberger.

	* Implemented large objects support.

	* psycopg/connection_int.c: removed increment of self->mark,
	now it is done directly in pqpath.c to make sure even the
	large object support gets it.

	* Starting 2.1 development.

2008-04-21  James Henstridge  <james@jamesh.id.au>

	* tests/test_quote.py (QuotingTestCase.test_unicode): If the
	server encoding is not UTF8, skip the unicode test and emit a
	warning.

2008-04-21  Jorgen Austvik <Jorgen.Austvik@sun.com>

	* tests/*.py: use the DSN constructed in tests/__init__.py.

	* tests/__init__.py: allow setting the host, port and user for the
	DSN used by the tests through the environment.

2008-03-17  Federico Di Gregorio <fog@initd.org>

	* Release 2.0.7.

2008-03-31  James Henstridge  <james@jamesh.id.au>

	* psycopg/connection_type.c (connection_dealloc): free
	connection->encoding with free() instead of PyMem_Free().

	* psycopg/connection_int.c (conn_connect): use malloc() to
	allocate connection->encoding instead of PyMem_Malloc(), since it
	is freed in other places with free() and assigned to with
	strdup().

2008-03-26  James Henstridge  <james@jamesh.id.au>

	* psycopg/typecast.c (typecast_from_c): fix up some reference
	leaks.  This leak affected a bounded set of objects, so doesn't
	account for any gradual leaks.

2008-03-19  James Henstridge  <james@jamesh.id.au>

	* psycopg/connection_int.c (conn_notice_callback): don't leak
	notice messages.

2008-03-17  Federico Di Gregorio <fog@initd.org>

	* psycopg/adapter_datetime.c: fixed double decref when using 
	a PyObject as a parameter in a nested call (line 415).

2008-03-17  James Henstridge  <james@jamesh.id.au>

	* psycopg/typecast.c (typecast_parse_time): give the correct
	return value for partially parsed time values.

	* psycopg/typecast_mxdatetime.c (typecast_MXDATE_cast): return
	NULL after setting DataError.  Also, don't treat it as an error if
	typecast_parse_time() returns 0 (as might happen if the remainder
	of the string is " BC").

	* psycopg/typecast_datetime.c (typecast_PYDATE_cast): return NULL
	after setting DataError.
	(typecast_PYDATETIME_cast): same here.
	(typecast_PYTIME_cast): same here.

	* tests/test_dates.py
	(CommonDatetimeTestsMixin.test_parse_incomplete_date): test that
	parsing incomplete date values results in DataError.
	(CommonDatetimeTestsMixin.test_parse_incomplete_time): same for
	times.
	(CommonDatetimeTestsMixin.test_parse_incomplete_time): same for
	datetimes.

2008-03-07  Jason Erickson  <jerickso@stickpeople.com>

	* psycopg/pqpath.c (pq_raise): if PSYCOPG_EXTENSIONS is not
	defined, raise OperationalError rather than
	TransactionRollbackError for deadlock or serialisation errors for
	protocol versions less than 3.

	* psycopg/psycopgmodule.c (psyco_connect): fix off by one error in
	calculating the length of the DSN.

2008-03-07  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (_pq_fetch_tuples): Don't call Python APIs
	without holding the GIL.

2008-02-27  James Henstridge  <james@jamesh.id.au>

	* NEWS: add some draft NEWS items for a 2.0.7 release.

	* runtests.py: add a harness to run all the psycopg tests against
	the version built by distutils.

2008-01-22  James Henstridge  <james@jamesh.id.au>

	* psycopg/typecast.c (typecast_pydatetime): make array static.
	(typecast_mxdatetime): same here.

	* psycopg/typecast_builtins.c (typecast_builtins): make array
	static.

	* psycopg/psycopgmodule.c: add hidden visibility to a bunch of
	global variables here.

	* psycopg/psycopg.h: add set QueryCanceledError and
	TransactionRollbackError to hidden visibility.

	* psycopg/*.[ch]: add const qualifier to various string arguments
	to functions (typecast functions and conn_switch_isolation_level).

2008-01-21  James Henstridge  <james@jamesh.id.au>

	* setup.cfg (define): remove PSYCOPG_DISPLAY_SIZE from default
	list of defines, as discussed on mailing list.  It slows down
	queries with very little benefit.

	* psycypg/*.h: apply HIDDEN to all global variables and functions
	that should not be exported from the module.  This results in a 5%
	reduction in code size and shortens the dynamic symbol table.

	* psycopg/config.h: If GCC >= 4.0 is installed, define the HIDDEN
	symbol to apply the "hidden" visibility attribute.

2008-01-19  James Henstridge  <james@jamesh.id.au>

	* tests/test_connection.py (ConnectionTests): add simple tests for
	the Connection and Cursor "closed" attributes.

	* psycopg/cursor_type.c (psyco_curs_get_closed): add a "closed"
	attribute to cursors.  It will be True if either the cursor or its
	associated connection are closed.  This fixes bug #164.

	* psycopg/pqpath.c (pq_raise): remove unused arguments to
	function, and simplify.
	(pq_resolve_critical): make function static, since it isn't being
	used outside of pqpath.c any more.

2008-01-17  James Henstridge  <james@jamesh.id.au>

	* ZPsycopgDA/DA.py (Connection.__init__): Default the encoding to
	UTF-8, fixing bug #190.
	(App.ImageFile): simplify ImageFile import using patch from
	chrism, fixing bug #198.

2008-01-16  James Henstridge  <james@jamesh.id.au>

	* tests/test_transaction.py (DeadlockSerializationTestCase): port
	over some tests for serialisation and deadlock errors,
	demonstrating that TransactionRollbackError is generated.
	(QueryCancelationTests): add a test to show that
	QueryCanceledError is raised on statement timeouts.

	* psycopg2da/adapter.py (_handle_psycopg_exception): rather than
	checking exception messages, check for TransactionRollbackError.

	* psycopg/pqpath.c (exception_from_sqlstate): return
	TransactionRollbackError for 40xxx errors, and QueryCanceledError
	for 57014 errors.
	(pq_raise): If we are using an old server, use
	TransactionRollbackError if the error message contains "could not
	serialize" or "deadlock detected".

	* psycopg/psycopgmodule.c (_psyco_connect_fill_exc): remove
	function, since we no longer need to store pointers to the
	exceptions in the connection.  This also fixes a reference leak.
	(psyco_connect): remove _psyco_connect_fill_exc() function call.

	* psycopg/connection.h (connectionObject): remove exception
	members from struct.

	* psycopg/connection_type.c (connectionObject_getsets): modify the
	exception attributes on the connection object from members to
	getsets.  This reduces the size of the struct.

	* lib/extensions.py: import the two new extensions.

	* psycopg/psycopgmodule.c (exctable): add new QueryCanceledError
	and TransactionRollbackError exceptions.

2008-01-16  James Henstridge  <james@jamesh.id.au>

	* tests/__init__.py (test_suite): add date tests to test suite.

	* tests/test_dates.py: add tests for date/time typecasting and
	adaption.

	* psycopg/adapter_mxdatetime.c (mxdatetime_str): add support for
	outputting BC dates (which involves switching them to one-based
	dates).  Also remove broken handling of microseconds.

	* psycopg/typecast.c (typecast_parse_date): if the string ends
	with "BC" adjust the year value to be a zero-based BC value as
	used by mx.DateTime (datetime doesn't support BC dates).
	(typecast_parse_time): ignore ' ', 'B' and 'C' in time strings
	rather than treating them as part of the seconds part of the time.

2008-01-14  James Henstridge  <james@jamesh.id.au>

	* psycopg/typecast_array.c (typecast_array_scan): set an initial
	value for quotes to keep gcc happy.

	* psycopg/*.c: add missing static modifier on many functions.

2008-01-12  James Henstridge  <james@jamesh.id.au>

	* tests/test_transaction.py
	(TransactionTestCase.test_failed_commit): Expect IntegrityError
	instead of OperationalError.

	* psycopg/pqpath.c (exception_from_sqlstate): new function that
	converts an SQLSTATE error code to the corresponding exception
	class.
	(pq_raise): use exception_from_sqlstate() to pick which exception
	to use when working with protocol version 3.
	(pq_complete_error): Let pq_raise() pick an appropriate exception
	rather than forcing OperationalError.

2008-01-11  James Henstridge  <james@jamesh.id.au>

	* psycopg/adapter_binary.c (binary_quote): apply Brandon Rhodes'
	patch from ticket #209 to check return value from
	PyObject_AsCharBuffer().  This fixes the segfault.
	(binary_quote): switch from PyObject_AsCharBuffer() to
	PyObject_AsReadBuffer() to support buffer objects that don't
	implement the bf_getcharbuf protocol.

	* tests/types_basic.py (TypesBasicTests.testBinary): Test round
	tripping of bytea buffers.  Currently segfaults.

	* psycopg/connection_int.c (conn_close): fix for new
	pq_abort_locked() prototype.
	(conn_switch_isolation_level): fix for new pq_abort_locked()
	prototype, and use pq_complete_error() to show error message.
	(conn_set_client_encoding): same here.

	* psycopg/pqpath.c (pq_execute_command_locked): remove static
	modifier.
	(pq_complete_error): same here.
	(pq_abort_locked): add pgres and error arguments.
	(pq_abort): call pq_abort_locked() to reduce code duplication.

2007-12-23  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (pq_execute_command_locked): add an error
	argument to hold an error when no PGresult is returned by PQexec,
	rather than using pq_set_critical().
	(pq_complete_error): new function that converts the error returned
	by pq_execute_command_locked() to a Python exception.
	(pq_begin_locked): add error argument.
	(pq_commit): use pq_complete_error().
	(pq_abort): use pq_complete_error().
	(pq_abort_locked): always call pq_set_critical() on error, and
	clear the error message from pq_execute_command_locked().
	(pq_execute): use pq_complete_error() to handle the error from
	pq_begin_locked().

	* psycopg/pqpath.c (pq_begin): remove unused function.

	* psycopg/connection_type.c (psyco_conn_commit): if conn_commit()
	raises an error, just return NULL, since it is now setting an
	exception itself.
	(psyco_conn_rollback): same here.

	* psycopg/connection_int.c (conn_commit): don't drop GIL and lock
	connection before calling pq_commit().
	(conn_rollback): same here.
	(conn_close): use pq_abort_locked().
	(conn_switch_isolation_level): same here.
	(conn_set_client_encoding): same here.

	* psycopg/pqpath.h: add prototype for pq_abort_locked().

	* psycopg/pqpath.c (pq_commit): convert function to run with GIL
	held, and handle errors appropriately.
	(pq_abort): same here.
	(pq_abort_locked): new function to abort a locked connection.

2007-12-22  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (pq_raise): add a "pgres" argument so we can
	generate nice errors not related to a particular cursor.
	(pq_execute): use pq_begin_locked() rather than pq_begin().  Use
	pq_raise() to handle any errors from it.

	* psycopg/pqpath.c (pq_execute_command_locked): helper function
	used to execute a command-style query on a locked connection.
	(pq_begin_locked): a variant of pq_begin() that uses
	pq_execute_command_locked().
	(pq_begin): rewrite to use pq_begin_locked().

2007-12-22  James Henstridge  <james@jamesh.id.au>

	* psycopg/config.h: only print debug messages if
	psycopg_debug_enabled is true.

	* psycopg/psycopgmodule.c (init_psycopg): set
	psycopg_debug_enabled to true if the $PSYCOPG_DEBUG environment
	variable is set.

2007-12-21  Federico Di Gregorio <fog@initd.org>

	* Applied win32 patch from Jason Erickson.

	* Applied patch from Thomas Lotze to use correct version
	for new Zopes.

2007-12-20  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (pq_execute): uncomment the "curs->pgres ==
	NULL" error handler after the PQexec() call.  This is needed to
	catch database disconnects (and probably other errors).  According
	to Federico, it was commented out to avoid a spurious error, so we
	should watch for problems.

2007-12-20  James Henstridge  <james@jamesh.id.au>

	* psycopg/pqpath.c (pq_raise): only remove the first 8 characters
	of the exception message if it actually gives the severity.

	* psycopg/pqpath.h (pq_resolve_critical): add prototype, since
	this function is being used from connection_int.c.

	* psycopg/psycopg.h: update psyco_set_error() prototype.

	* psycopg/psycopgmodule.c (psyco_errors_init): set pgerror, pgcode
	and cursor class attributes to None on psycopg2.Error so that the
	attributes will always be available (simplifies error handling).
	(psyco_set_error): add const qualifiers to msg, pgerror and pgcode
	arguments.
	Don't bother setting pgerror, pgcode or cursor to None if they are
	not provided -- the class defaults take care of this.

2007-11-11  Daniele Varrazzo  <daniele.varrazzo@gmail.com>

	* Use escape string syntax for string escape if connected to a
	  server requiring it.

2007-11-09  Daniele Varrazzo  <daniele.varrazzo@gmail.com>

	* Use escape string syntax for binary escape if connected to a
	  server requiring it.

	* Put a limit on the number of notices stored in the connection.

2007-10-21  Daniele Varrazzo  <daniele.varrazzo@gmail.com>

	* Fixed bug #192 (Decimal support not safe for use with multiple sub
	  interpreters) as proposed by Graham Dumpleton.

2007-09-08  Federico Di Gregorio  <fog@initd.org>

	* Added MonoDevelop project, yahi!

2007-09-06  Federico Di Gregorio  <fog@initd.org>

	* Fixed bug #194.

2007-09-01  Federico Di Gregorio  <fog@initd.org>

	* Added "name" parameter to all .cursor() calls in extras.py.

2007-05-29  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.6.

	* ZPsycopgDA/DA.py: removed call to now obsolete .set_type_casts().

	* Applied patch from mkz (ticket #187) to add error handling when

	* psycopg/connection_type.c: added support for a new method
	.get_transaction_status() that returns the backend transaction
	status as libpq knows. Also added some symbolic constants to
	psycopg.extensions module (TRANSACTION_STATUS_XXX).

2007-04-14  Federico Di Gregorio  <fog@initd.org>

	* psycopg/psycopg.h: fixed probable typo in definition of
	CONV_CODE_PY_SSIZE_T: d -> i for Python < 2.5.

	* Fixed some of the examples.

2007-04-13  Federico Di Gregorio  <fog@initd.org>

	buffer size a compile-time parameter.

	* Applied patch from David Rushby: typecast_binary.c cleanup.

	* Applied patch from David Rushby for int->size_t transition.

2007-04-12  Federico Di Gregorio  <fog@initd.org>

2007-04-11  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.6b2.

	* psycopg/cursor_type.c: added check to raise an error when
	some crazy programmer tries to use different argument formats

2007-02-11  Federico Di Gregorio  <fog@initd.org>

	* psycopg/pqpath.c: ported psycopg1 patch from #135.

	* psycopg/connection_type.c: now the password is obfuscated after we try

2007-01-20  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.6b1.

	* Added encodings patch from Karsten Hilbert.

2007-01-19  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapt_list.c: added support for None. And this closes
	the other half.

	* psycopg/typecast_array.c: added support for detecting the NULL
	special string and converting it as a real NULL if not enclosed in
	quotes. This closes half of #154.

2007-01-16  Federico Di Gregorio  <fog@initd.org>

	* psycopg/connection_type.c: .set_client_encoding() now converts the
	argument to upper case to make sure it has the same case of the entries
	in the PostgreSQL -> Python encoding conversion table.

	* lib/extras.py: merged DictCursor from #143 and renamed it 
	RealDictCursor because allows access by cursor keys _only_.
	Also cleaned up a little bit the implementation of both DictCursor
	and RealDictCursor by introducing DictCursorBase.

	* psycopg/pqpath.cs: new checks for NULL values (meaning an
	  exception was raised) in all method calls (fixes #134).

	* psycopg/psycopgmodule.c: applied LATIN patch from #148.

	* psycopg/connection_type.c: obfuscate password after using it.

	* lib/extras.py: moved SQL_IN to extensions.py; we're now officially
	adapting tuples.

	* psycopg/adapt_mxdatetime.c: fixed #137 by accessing the 'date' and
	'time' attributes of the mx.DateTime instance: they are always in ISO
	format.

	* psycopg/typecast_datetime.c: fixed problem with year > 9999.

2006-10-29  Federico Di Gregorio  <fog@initd.org>

	* Applied patch from Jason Erickson to make psycopg build
	again on win32 (closes: #132).

2006-09-30  Federico Di Gregorio  <fog@initd.org>

	* ZpsycopgDA/DA.py: applied the infinity patch from 1.1 (fixes #122).

	* psycopg/adapter_datetime.py: fixed conversion problem with seconds
	in the (59,60) range (fixes #131).

	* ZpsycopgDA/DA.py: we now split on GMT+, GMT-, + or -. This should
	fix bug #129.

	* psycopg/adapter_datetime.py: now TimeFromTicks and
	TimestampFromTicks both accept fractionary seconds (fixes #130).

2006-09-23  Federico Di Gregorio  <fog@initd.org>

	* lib/errorcodes.py: added list of all PostgreSQL error codes
	compiled by Johan Dahlin.

	* psycopg/psycopg.h: applied compatibility macros from PEP 353.

	* Applied patch 1/3 from Piet Delport; from his email:
	   
	   psycopg2-Py_ssize_t-input.diff adjusts variables used for parameters
	   and return values.  These changes only prevent overflowing on values
	   greater than 32-bits, so they're not as critical as the other two
	   patches.  I tried to leave places unchanged where the input size is
	   already constrained to sizeof(int), but i might have missed a few
	   either way, not being too familiar with the codebase.

	* Applied patch 2/3 from Piet Delport; from his email:
	   
	   psycopg2-Py_ssize_t-output.diff adjusts variables used as outputs
	   from CPython API calls:  without it the calls try to write 64 bits
	   to 32 bit locations, trampling over adjacent values/pointers,
	   and segfaulting later.

	* Applied patch 1/3 from Piet Delport; from his email:
        
	   psycopg2-PyObject_HEAD.diff adds missing underscores to several
           "PyObject_HEAD" declarations.  As far as i can tell from gdb, the 
	   "PyObject HEAD" versions end up accidentally meaning almost exactly
	   the same, but get aligned differently on AMD64, resulting in wrong
	   size calculation and memory corruption later.

2006-09-11  Federico Di Gregorio  <fog@initd.org>

	* Fixed syntax error in lib/extras.py (see #123)

2006-09-02  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapter_mxdatetime.c, psycopg/psycopgmodule.c: fixed last
	problem with non-constant initializers.

	* psycopg/connection_type.c: applied patch from Joerg Sonnenberger
	to fix a double mutex destroy.

	* Release 2.0.5.1.

	* psycopg/cursor_type.c: applied patch from Jason Erickson to
	build on MSVC and older gcc.

2006-09-01  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.5.

	* Fixed patch from #119, see tracker for details.

	* Preparing release 2.0.5.

	* psycopg/psycopgmodule.c: fixed filling of connection errors
	to include OperationalError.

	* setup.py: removed pydatetime option from initialize_options
	to make sure that the value in setup.cfg is used.

	* psycopg/psycopgmodule.c: applied patch from jdahlin (#120)
	to have .connect() accept either a string or int as the port
	parameter.

	* psycopg/adapter_binary.c: applied patch from jdahlin (#119)
	to fix the segfault on empty binary buffers.

	* psycopg/connection_type.c: added .status attribute to expose
	the internal status.

	* psycopg/pqpath.c: applied patch from intgr (#117) to fix
	segfault on null queries.

	* psycopg/cursor_type.c: applied patch from intgr (#116) to
	fix bad keyword naming and segfault in .executemany().

	* ZPsycopgDA/DA.py: applied ImageFile patch from Charlie
	Clark.

	* lib/pool.py: applied logging patch from Charlie Clark.
	It will probably get a makeup and be moved to the top-level
	module later.

2006-08-02  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.4.

	* Fixed bug in float conversion (check for NULL string was
	erroneously removed in 2.0.3!)

2006-07-31  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.3.

	* psycopg/cursor_type.c: applied patch from jbellis (#113) to
	allow column selection in .copy_from().

	* psycopg/psycopgmodule.c: fixed memory leak in custom exceptions
	(applied patch from #114).

2006-07-26  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapter_datetime.c (pydatetime_str): fixed error
	in conversion of microseconds for intervals and better algo
	(thanks to Mario Frasca.)

2006-06-18  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapter_binary.c: same as below.

        * psycopg/adapter_qstring.c: does not segfault anymore if 
	.getquoted() is called without preparing the qstring with 
	the connection.

2006-06-15  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast_basic.c: fixed problem with bogus
	conversion when importing gtk (that was crazy, I didn't
	understand why it happened but the new code just fixes it.)

	* ZPsycopgDA/db.py: better type analisys, using an hash
	instead of a series of if (variation on patch from Charlie
	Clark.)

2006-06-11  Federico Di Gregorio  <fog@initd.org>

	* Release 2.0.2.

	* psycopg/typecast_array.c (typecast_array_cleanup): fixed a
	problem with typecast_array_cleanup always returning the new
	string length shorter by 1 (Closes: #93).

	* psycopg/adapter_binary.c: as below.

	* psycopg/adapter_qstring.c: wrapped #warning in #ifdef __GCC__
	because other compilers don't have it and it will just break
	compilation (patch from jason, our great win32 builder).

	* psycopg/adapter_list.c: applied patch to adapt an empty list
	into an empty array and not to NULL (from iGGy, closes: #108).

	* psycopg/cursor_type.c: applied patch from wkv to avoid
	under-allocating query space when the parameters are not of the
	right type (Closes: #110).

	* psycopg/connection_int.c: applied patch from wkv to avoid off 
	by one allocation of connection encoding string (Closes: #109).

2006-06-09  Federico Di Gregorio  <fog@initd.org>

        * Release 2.0.1.

	* Fixed some buglets in ZPsycopgDA (was unable to load due
	to shorter version number in psycopg module.)

2006-06-08  Federico Di Gregorio  <fog@initd.org>
	
	* Release 2.0.

	* ZPsycopgDA/DA.py: removed Browse table for 2.0 release; we'll
	add it back later.

2006-05-26  Federico Di Gregorio  <fog@initd.org>

	* Applied better PostgreSQL patch from AA.

2006-05-24  Federico Di Gregorio  <fog@initd.org>

	* Enabled 8.1.4 security fix only when the version is >= 8.1.4, fall
	back to old code otherwise.
	
	* psycopg/adapter_qstring.c: now quote using PQescapeStringConn if
	available. 

	* psycopg/adapter_binary.c: now quote using PQescapeByteaConn if
	available. 

2006-04-38  Federico Di Gregorio  <fog@initd.org>

	* setup.py: fixed little problem with mx_include_dir as suggested
	by kvc (this closes #102).

2006-04-24  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapter_pboolean.c: added the possibility to format boolean
	values as "true" and "false" instead of "'t'" and "'f'".

2006-03-08  Federico Di Gregorio  <fog@initd.org>

	* lib/extras.py: added .next() to DictCursot to support iteration.

2006-03-02  Federico Di Gregorio  <fog@initd.org>

	win32, as documented in #92.

2006-02-11  Federico Di Gregorio  <fog@initd.org>

	* psycopg/psycopgmodule.c: applied fix for memory overflow in
	connect() (reported by solt, #91.)

	* setup.py: applied patch from lbruno.

2006-01-11  Federico Di Gregorio  <fog@initd.org>

	* setup.py: does not report an error in pg_config unless the pg_config
	was explicitly set (allows for building with old options.) 

2006-01-06  Daniele Varrazzo  <daniele.varrazzo@gmail.com>

	* setup.py: libpq.dll not used anymore. win32 setup uses pg_config too.

2006-01-05  Federico Di Gregorio  <fog@initd.org>

	* psycopg/psycopgmodule.c (psyco_set_error): added function to set extra
	parameters on ProgrammingError instances. Also modified all occurances of
	PyErr_SetString(ProgrammingError,...) to psycopg_set_error(). 

	* setup.{cfg,py}: we now use pg_config to locate PostgreSQL libraries
	and headers (modified patch from lbruno, see #70.)

2006-01-01  Federico Di Gregorio  <fog@initd.org>

	* Preparing release 2 beta 7.

	* MANIFEST.in: we now distrbute pre-built documentation (still need
	to add to setup.py the code necessary to build docs as part of the
	build process.)

	* psycopg/connection_int.c: PostgreSQL encoding names are now force
	uppercase (after all PostgreSQL documentation reports them this way.)

2005-12-11 Federico Di Gregorio <fog@initd.org>

	* psycopg/typecast_array.c (typecast_array_cleanup): added functio
	to cleanup the "[...]=" part of an array result. This probably will
	need some more work for nested arrays but it fixed every test I was
	able to write. (Closes: #80)

2005-12-11  Federico Di Gregorio  <fog@initd.org>

	* setup.py: half-applied patch from Tavis to specify mx_include_dir
	in setup.cfg.

	* psycopg/typecast.c (typecast_parse_time): cz limit in the while
	loop is 6, not 5. This solve the problem with "fractionary" time zones
	and fixes #78. 

2005-12-06  Federico Di Gregorio  <fog@initd.org>

	* lib/extras.py: added .callproc() to DictCursor as suggested
	by Philip Semanchuk.

2005-11-29  Federico Di Gregorio  <fog@initd.org>

2005-11-26  Daniele Varrazzo  <daniele.varrazzo@gmail.com>

	* psycopg/psycopgmodule.c: fixed exceptions refcount.

	* Fixed lots of doctrings and added Epydoc-generated docs support.

2005-11-24  Federico Di Gregorio  <fog@initd.org>

	* sandbox: added all the test and creash-me files to the repository.

	* psycopg/typecast.c (typecast_dealloc): now directly calls
	PyObject_Del to avoid to segfault.

2005-11-20  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast.c: fixed problem with microseconds conversion by
	applying slightly modified patch from Ronnie Mackay.

2005-11-19  Federico Di Gregorio  <fog@initd.org>

	* lib/extensions.py: COMMITED -> COMMITTED. (Closes: #73)

	* doc/extensions.rst: included Daniele's work after minor cosmetic changes
	like using the new constants instead of numbers for transaction isolation
	levels.

2005-11-17  Federico Di Gregorio  <fog@initd.org>

	* ZPsycopgDA/pool.py: fixed connections leak by using the new name
	(PersistentConnectionPool) for the old connection pool class.

2005-11-16  Federico Di Gregorio  <fog@initd.org>

	* Preparing release 2.0 beta 6.
	
	* psycopg/adapter_mxdatetime.c: fixed all problems with mx conversions.
	
	* psycopg/typecast.c: now the timezone is set correctly even if there
	are no microseconds and/or the offset is 0;

	* examples/encoding.py: fixed example by using python utf8 encoding for
	the whole file.

	* lib/__init__.py: very nice hack from Harald Armin Massa to allow
	py2exe and similar tools to do their work without problems.

2005-11-15  Federico Di Gregorio  <fog@initd.org>

	* psycopg/psycopgmodule.c: now bails out with correct exception when one
	of the needed modules can't be imported (should fix #32.)

2005-11-14  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast.c: added typecast_parse_date and typecast_parse_time
	functions to do locale-safe date/time parsing. This would probably also
	speed-up psycopg a little bit.

2005-11-07  Federico Di Gregorio  <fog@initd.org>

	* psycopg/pqpath.c: fixed problem with uninitialized value (all this was
	started by replacing calloc() calls with PyMem_Malloc().)

2005-11-04  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast.c: a lot of changes:
	  - made typecast a new-style type
	  - removed coerce code and implemented the richcompare protocol that
	    allows to compare objects of different types
	  - much better __cmp__ method that allows to compare two typecast
	    objects and returns True if any two of the mapped oids match
	  - any object that can be used as an int works as right-hand operand
	    in __cmp__ operations 

	* psycopg/typecast_datetime.c: now typecast_PYINTERVAL_cast limit the
	scan to 'len' characters in the string (should fix #65.)

2005-11-03  Federico Di Gregorio  <fog@initd.org>

	* Applied patch from Daniele Varazzo to enable Decimal on Python
	2.3 when the module is available (run-time check, nice.)

	* setup.cfg: added include_dirs line for SUSE 9.3.

2005-10-22  Federico Di Gregorio  <fog@initd.org>

	* psycopg/cursor_type.c: added support for named cursors:
	  - .fetchXXX() methods now execute a FETCH if the cursor is named
	  - .execute() executes a DECLARE if the cursor is named
	  - .execute() fails if a named cursor is used in autocommit
	  - .executemany() can't be called on named cursors
	  - .scroll() executes a MOVE if the cursor is named
	  - .close() executes a CLOSE if the cursor is named
	  Also, a "transaction mark" was added to both the connection and the
	  cursor and an exception is raised when using a named cursor unless the
	  two marks correspond.

	* psycopg/connection_int.c: snprintf->PyOS_snprintf.

	* psycopg/psycopgmodule.c: snprintf->PyOS_snprintf.

	* psycopg/cursor_type.c: changed self->query type from C string to
	PyObject* to better manage queries in named cursors.

	* psycopg/psycopgmodule.c: cleaned up exception names (now the errors
	is printed as psycopg2.Error and not as the confusing
	psycopg2._psycopg.Error.)

2005-10-20  Federico Di Gregorio  <fog@initd.org>

	* lib/pool.py: renamed ThreadedConnectionPool to PersistentConnectionPool
	and added a connection pool that allows multiple connections per thread
	as ThreadedConnectionPool (courtesy of Daniele Varrazzo.)

2005-10-19  Federico Di Gregorio  <fog@initd.org>

	* Releasing 2.0 beta 5.
	
	* psycopg/adapter_mxdatetime.c: reverted to old strftime method to format
	mx.DateTime objects; the new method didn't worked in some corner-cases.
	This makes impossible to have more than 2 decimal places for seconds but
	at least we get the time right every time.

2005-10-18  Federico Di Gregorio  <fog@initd.org>

	* NOTIFY is back end working.

	* psycopg/connection_type.c: fixed problem with initialization of
	notifies list (also fixed small memory leak in connection dealloc.)

	* psycopg/cursor_type.c: added per-cursor type-casters dictionaries.

2005-10-18  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast.c: temporary fix to typecasting objects to return
	False for any comparaison except an integer in self.values (i.e., we
	don't raise an exception anymore on a coerce error.) Epydoc is now
	happy.

	* psycopg/config.h: ZETA config.h patch from Charlie Clark.

	* examples/threads.py: fixed small typo: psycopg -> psycopg2.

	* Big cleanup of unsigned chars to tame gcc 4.

	* Big cleanup of module names (i.e., psycopg2._psycopg everywhere.)
	
	* psycopg/config.h: added fake localtime_r for platforms missing it

	* psycopg/cursor_type.c: cursors now have a FixedOffsetTimezone
	tzinfo_factory by default.

	* psycopg/adapter_datetime.c: added tzinfo argument to psycopg2.Time and
	psycopg2.Timestamp. Also now TimestampFromTicks sets the tzinfo object
	to psycopg2.tz.LOCAL.

2005-10-17  Federico Di Gregorio  <fog@initd.org>

	* psycopg/adapter_datetime.c: we now use localtime() instead of gmtime()
	to accound for the local time-zone in timestamps.

	* psycopg/connection_type.c: fixed docstring for .cursor().

	* psycopg/psycopgmodule.c: added useful docstring for .connect().

2005-10-08  Federico Di Gregorio  <fog@initd.org>

	* psycopg/connection_type.c: isolation level upper bound set to 2.

	* lib/psycopg1.py: explicitly set isolation level to 2 on .connect()
	to mimic psycopg 1 behaviour.

	* psycopg/connection_int.c: now set isolation level from
	default_transaction_isolation backend environment value.

	* psycopg/pqpath.c: removed serialization level 3: now everybody
	(except me) has to use the mnemonics defined in psycopg2.extensions.

	* lib/extensions.py: Added mnemonics for serialization levels.

2005-10-02  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (psyco_curs_callproc): applied callproc
	patch from Matt Goodall (added a check on _psyco_curs_execute
	return value and substituted malloc/free with PyMem versions.) 

2005-10-01  Federico Di Gregorio  <fog@debian.org>

	* psycopg/connection_int.c: fixed segfault by moving PyErr_Format
	after GIL acquisition (closes: #50).

	* psycopg/connection_type.c: applied patch from Matt Goodall to
	fix some doc strings.

2005-09-23  Federico Di Gregorio  <fog@debian.org>

	* lib/pool.py: applied patch from piro to avoid the scan of the
	whole connection array on getconn().

2005-09-12  Federico Di Gregorio  <fog@initd.org>

	* lib/pool.py: Applied psycopg->psycopg2 patch to from bug #35.

	* ZpsycopgDA/db.py: fixed problem with OperationalError that
	resulted in cryptic message to Zope users ("'OperationalError' is
	not defined".)
	
2005-08-23  Federico Di Gregorio  <fog@debian.org>

	* setup.py: applied patch from Daniele Varrazzo to avoid segfaults
	when compiling with migw for Python 2.4.x.

	* psycopg/adapter_mxdatetime.c (mxdatetime_str): ported code from 1.1.x
	to convert mxDateTime object preserving the precision of fractional
	seconds.

2005-08-22  Federico Di Gregorio  <fog@debian.org>

	* ZPsycopgDA/*.py: psycopg -> psycopg2. 

	* setup.py: modified to install the module components under
	psycopg2 on windows too (thanks to Daniele Varrazzo.)

2005-08-07  Federico Di Gregorio  <fog@debian.org>

	* psycopg/config.h: added __sun__ to the symbols checked for round()

2005-07-21  Federico Di Gregorio  <fog@debian.org>

	* psycopg/adapter_datetime.c (psyco_XXXFromTicks): fixed the 1900
	years offset reported by Jeroen van Dongen (see ticket #33).

	* lib/psycopg1.py: fixed .dictfetchrow() to return None if fetchone()
	returns None instead of raising an exception.
	
	* ZPsycopgDA/icons: replaced corrupted icons with good ones. 

2005-06-13  Federico Di Gregorio  <fog@initd.org>

	* psycopg/psycopgmodule.c (psyco_connect): changed the port keyword
	parameter type to int (instead of string); this should fix #23.
	
	* psycopg/cursor_type.c (_psyco_curs_execute): now checks for
	empty queries and raise a ProgrammingError if appropriate (closes:
	#24).

	* psycopg/adapter_datetime.c (psyco_TimestampFromTicks): "Hmmm,
	looks like someone forgot that C expects months to start counting

	was me: fixed.

2005-05-31  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (_psyco_curs_execute): if a
	UnicodeEncodeError is raised during the converion of a unicode

	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?)

2005-05-09  Federico Di Gregorio  <fog@debian.org>

	* Release 2.0 beta 1.

	* psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): fixed a

	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.

	"cast", holding the typecaster currently in use.

	* 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().

	* psycopg/cursor_type.c (_psyco_curs_execute): splitted away
	python argument parsing from the real execute code, to later allow
	for .executemany().

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

	truncate the string anyway!)
	
	* COPY TO implemented using both old and new (v3) protocol.

	* 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.

	* 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. :/)

	Andrea Arcangeli.)

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

	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.

	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.

	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.

	* psycopg/cursor_type.c (_psyco_curs_buildrow_*): unified normal
	and factory code into the _psyco_curs_buildrow_fill function; no

	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>

	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.

	* psycopg/adapter_qstring.h: remove encoding information from
	qstring adapter and moved it into psycopg module.

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

	* psycopg/cursor_type.c (_psyco_curs_prefetch): added check for
	asynchronous fetch by wrong cursor.

	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

	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

	* 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

	* Release 1.99.5 (bug-fixing and reorganization)

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