psycopg2/ChangeLog

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
	calling conn_commit() and conn_rollback(). Fixes #187.

	* cursor.copy_expert() implementation by David Rushby (copy_expert
	set 5/5.)

	* SQL validation refactor patch from David Rushby (copy_expert
	set 4/5.)

	* Reference count leak fix from David Rushby (copy_expert set 3/5.)

	* 64 bit fix patch from David Rushby (copy_expert set 2/5.)

	* Applied whitespace normalization patch from David Rushby (copy_expert
	set 1/5.)

2007-04-25  Federico Di Gregorio  <fog@initd.org>

	* 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>

	* Applied slighly modified patch from daniel (#176). Made
	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>

	* Applied patch from Jason Erickson to fix win32 build glitches.

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
	in the same query string. Fixes #162.

	* Applied patch from David Rushby to fix win32 builds.

2007-04-10  Federico Di Gregorio  <fog@initd.org>

	* Applied patch from David Rushby to fix mem and ref leaks in
	  psycopg2.connect().

	* Applied super-patch from David Rushby to fix Python 2.5 and 64
	bit problems (all of them, kudos!)

2007-02-22  Federico Di Gregorio  <fog@initd.org>

	* Added support for per-connection and per-cursor typecasters.

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
	to connect to the backend. This really fixes #147.

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.

	(applied patch from #114).

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

	* psycopg/adapter_datetime.c (pydatetime_str): fixed error

	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

	* 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).

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.

	* Applied better PostgreSQL patch from AA.

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

	by kvc (this closes #102).

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

	* psycopg/adapter_pboolean.c: added the possibility to format boolean

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

2006-03-02  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

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

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

	PyObject_Del to avoid to segfault.

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

	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.)

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.)

	* examples/notify.py: added NOTIFY example.

	* 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().

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

	to convert mxDateTime object preserving the precision of fractional
	seconds.

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

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

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). 

2005-07-17  Federico Di Gregorio  <fog@debian.org>

	* Release 2.0 beta 4.

	* lib/extras.py (DictConnection.cursor): added DictConnection to
	make easier to retrieve data in DictRows.

2005-06-24  Federico Di Gregorio  <fog@initd.org>

	* psycopg/typecast_datetime.c (typecast_PYINTERVAL_cast): applied patch
	from Geert Jansen to fix interval bug due to overflow.

2005-06-18  Federico Di Gregorio  <fog@initd.org>

	cut&paste problems.
	
	* MANIFEST.in: added missing files to do bdist_rpm.
	
	* 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).
	
	* setup.py: psycopg module renamed to psycopg2.

2005-06-02  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (_psyco_curs_execute): fixed segfault when
	not passing string or unicode to .execute().

2005-06-01  Federico Di Gregorio  <fog@debian.org>

	* examples/fetch.py: added example about using DECLARE CURSOR.

	* psycopg/adapter_datetime.c (psyco_TimestampFromTicks): "Hmmm,
	looks like someone forgot that C expects months to start counting
	from 0, but the Python date routines start counting from 1." That
	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
	query we let it propagate insead of segfaulting.
	
2005-5-27  Federico Di Gregorio,  <fog@lana.initd.org>

	* tests/types_basic.py: fixed float and binary tests.

2005-05-26  Federico Di Gregorio  <fog@debian.org>

	* Release 2.0b3.

	* ZPsycopgDA/db.py (DB.convert_description): isolated description
	conversion (and fixed the conversion as per #18).

	real. :/  Also fixed the type-casters (psycopg 2 added the extra
	cursor parameter) as reported in #18.

	subclasses calling cursor.execute(self, query, None).

2005-05-18  Federico Di Gregorio  <fog@debian.org>

	* ZPsycopgDA/DA.py (ALLOWED_PSYCOPG_VERSIONS): updated to work
	with 2.0b2 only (will support only the exact version untill final
	2.0 release.)

	* setup.py: Applied combined patch from Daniele Varrazzo and Jason
	Erickson to build on win32 using MSVC or mingw.

2005-05-15  Federico Di Gregorio  <fog@debian.org>

	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

	chunk/buffer object patch to allow round-trip of buffer objects
	(BYTEA columns.) 

	* psycopg/cursor_type.c (psyco_curs_executemany): applied slightly

	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().

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

	* psycopg/cursor_type.c (_psyco_curs_buildrow_fill): modified to
	call typecast_cast().
	
	* psycopg/typecast.c (typecast_call/typecast_cast): modified
	typecast_call to use the new typecast_cast that avoids one string
	conversion on every cast.

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

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

	* psycopg/typecast.h: added array casting functions.

	* scripts/maketypes.sh: does not generate pgversion.h anymore. 

	* Updated all examples for the release.

2005-03-02  Federico Di Gregorio  <fog@debian.org>

	* Release 1.99.12.
	
	* psycopg/adapter_*.c: added __conform__ to all adapters.
	
	* psycopg/adapter_qstring.c (qstring_quote): we now use
	PyString_AsStringAndSize() instead of strlen() that would stop at
	the first embedded \0 (but note that libpq quoting function will
	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.

	* 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. :/

	* psycopg/microprotocols.c (microprotocols_adapt): fixed small
	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>

	* examples/myfirstrecipe.py: fixed adapter registration. 

2005-2-7  Federico Di Gregorio  <fog@initd.org>

	* setup.py: added patch by Valentino Volonghi to build on MacOS X.

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. :/)

	* psycopg/cursor_type.c (_psyco_curs_has_write_check): added check
	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.

2005-01-18  Federico Di Gregorio  <fog@debian.org>

	* psycopg/pqpath.c (_pq_fetch_tuples): ported scale/precision fix
	from psycopg 1.1.

	* LICENSE: detailed licensing information. Re-licensed some parts
	under BSD-like to allow integration is pysqlite.

2005-01-13  Federico Di Gregorio  <fog@debian.org>

	* ZPsycopgDA/db.py (DB.query
	): ported ZPsycopgDA connection fix
	from psycopg 1.1.

	* lib/*.py: added pydoc-friendly messages.

2005-01-12  Federico Di Gregorio  <fog@debian.org>

	* Added debian directory (thanks to W. Borgert who sent initial
	patch based on cdbs.)

2004-12-20  Federico Di Gregorio  <fog@debian.org>

	* psycopg/pqpath.c (pq_execute): removed multiple calls to
	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.

	exception if a cursor tries to .execute() while an async query is
	already in execution froma  different cursor. 

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

	* psycopg/connection_type.c (psyco_conn_cursor): renamed 'cursor'
	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.

2004-10-02  Federico Di Gregorio  <fog@debian.org>

	* 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.

	*  examples/dialtone.py: Added adapt() example by Valentino
	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>

	* psycopg/pqpath.c (_pq_fetch_tuples): ported rowcount fix from
	1.1.15.

	.fetchall() and .fetchmany() returning None instead of [] on empty
	result sets.

	* Release 1.99.8.

2004-08-28  Federico Di Gregorio  <fog@debian.org>

	* psycopg/cursor_type.c (psyco_curs_execute): added processing of
	unicode queries.

	* 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.

	* 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.

	* psycopg/typecast_basic.c (typecast_BINARY_cast): reverted to
	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
	round() with micro() when rounding seconds (fixes bugs reported by

	* psycopg/pqpath.c (pq_set_critical): allow for a custom message
	insted of the one from PQerrorMessage.
	(pq_resolve_critical): added argument to specify if connection is

	added extension methods related to async queries. 

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

	* Release 1.99.7.

	* examples/tz.py: added example about time zones.

	* psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): create
	FixedOffsetTimezone for postgresql "timestamp with time zone"
	types.

	* lib/tz.py: added (even more than) needed tzinfo classes.

	avoid dereferencing empty pointer (from 1.1.x)
	(psyco_curs_execute): now we save the query in self->query instead
	of freeing the memory ASAP.

	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

	* 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).

	support for utf8 and latin1 encodings.

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

	* psycopg/connection_int.c (conn_close): does not use libpq
	functions on NULL pgconn (this can happen when conn_close is
	called after a failed PQconnect.)

2004-02-29  Federico Di Gregorio  <fog@debian.org> 

	* Release 1.99.2 (alpha 3).
	
	* psycopg/cursor_type.c: added .rownumber and .connection
	attributes. Also added .scroll(), .next() and .__iter__() methods
	(see DBAPI2-.0 extensions on PEP.)

	added connection method .set_isolation_level(). Also added all
	error objects to the connection (see DBAPI2-.0 extensions on PEP.)

	* psycopg/connection_int.c (conn_switch_isolation_level): added
	isolation level switching code.

	* setup.py: removed all references to PSYCOPG_NEWSTYLE: support
	for python < 2.2 has been dropped.

	* typecast_basic.c (typecast_BINARY_cast): now binary objects are
	returned as true buffers.

	* adapter_binary.*: added adapter for buffers and binary (bytea)
	objects.

	* Release 1.99.1 (alpha 2).

	* adapter_mxdatetime.*: added adapters for all mx.DateTime types.

2004-02-28  Federico Di Gregorio  <fog@debian.org>

	* cursor_type.c (_mogrify): complete rework of the mogrification
	code to use the microprotocols_adapt function.

	* typecast_basic.c (typecast_BOOLEAN_cast): we now return real
	Py_True and Py_False values.

	* connection_int.c (conn_commit/conn_rollback): added code to
	commit/rollback and connection methods. 

2004-01-04  Federico Di Gregorio  <fog@debian.org>

2003-08-01  Federico Di Gregorio  <fog@debian.org>

	* cursor_type.c (_mogrify_sequence): added sequence mogrification,
	can be done better, on the dict model.

2003-07-28  Federico Di Gregorio  <fog@debian.org>

	* typeobj_qstring.c: added quoted strings (can use both own code,
	like psycopg 1.x or PQescapeString from lipq.)

2003-07-21  Federico Di Gregorio  <fog@debian.org>

	* connection_type.c (psyco_conn_close): added .close()
	method. wow.

	* cursor_*.c: added basic cursor interface (new-style.)

2003-07-20  Federico Di Gregorio  <fog@debian.org>

	* psycopg/*: beginning of new source layout. if you think this
	changelog is somewhat empty, you're right. look at
	doc/ChangeLog-1.x for psycopg 1.x changelog just before the
	branch.
