to PostgreSQL NaN numeric values. Also added tests.
2010-02-15 Daniele Varrazzo <daniele.varrazzo@gmail.com>
* lib/errorcodes.py: Updated to PostgreSQL 8.4; added lookup() function.
2010-02-12 Daniele Varrazzo <daniele.varrazzo@gmail.com>
* Stop the loop variable used to create __all__ leaking in the module.
* Fixed Inet constructor.
* Fixed docstring for 'QueryCanceledError' exception.
2010-02-10 Federico Di Gregorio <fog@initd.org>
* lib/extensions.py: Binary was not imported from _psycopg; now it is
* lib/__init__: SQL_IN adapter is now automatically registered.
* ZPsycopgDA/db.py: removed logging debug calls; psycopg does
not depend on the logger module.
2010-02-12 Federico Di Gregorio <fog@initd.org>
* License migration: psycopg2 is now LGPL3 + OpenSSL exception.
* TODO file was never updated so lets remove it.
2010-02-10 Federico Di Gregorio <fog@initd.org>
* lib/extras.py: fixed register_tstz_w_secs() error as reported by
Karsten Hilbert.
2009-11-25 Federico Di Gregorio <fog@initd.org>
* psycopg/microprotocols.c: "can't adapt" message now includes full
type information (adapted patch from Eric Chamberlain).
* tests/types_basic.py: fixed test broken by float precision fix.
2009-11-09 Federico Di Gregorio <fog@initd.org>
* psycopg/adapter_pfloat.c: applied patch from Remy Blankto fix float
loss of precision.

deadlocks with multiple threads using the same connection.
2009-08-08 Federico Di Gregorio <fog@initd.org>
* Release 2.0.12.

lo_write: apparently the large objects code does not like non-blocking
connections.
* setup.py: fixed version detection for PostgreSQL rc, as
suggested by Sok Ann Yap.
* ZPsycopgDA/db.py: applied serialization error retry from Brian
Sutherland.
* Implemented connection.reset() method to reset the connection to
well-know default parameters. This is much faster than closing and
reopening the connection. (Suggested by a bug report by Glenn
Maynard.)
* psycopg/cursor_type.c: unified size macro definitions in COPY TO
and COPY FROM operations: now the buffer for column names is 8192
bytes that should be enough even for very large tables.
2009-05-19 Federico Di Gregorio <fog@initd.org>
* Applied patch from Robert Munro to fix version check
in ZPsycopgDA.
2009-05-10 Federico Di Gregorio <fog@initd.org>

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>

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>

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>

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>

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!
