Bug reported by Anton Kovalev. * dropped PSYCOPG_OWN_QUOTING. * psycopg/connection_int.c: Fixed access to freed memory in conn_get_isolation_level(). Bug reported by Anton Kovalev. 2010-10-06 Daniele Varrazzo * Merged James Henstridge work on two-phase commit support. 2008-07-24 James Henstridge * tests/test_psycopg2_dbapi20.py (Psycopg2TPCTests): hook up two phase commit tests. * psycopg/xid_type.c (xid_len, xid_getitem): implement sequence behaviour, as required for transaction IDs. (XidType): There is no point in allowing subclasses of Xid. 2008-07-23 James Henstridge * psycopg/connection_type.c (psyco_conn_xid): add a Connection.xid() method that instantiates Xid objects. * psycopg/psycopgmodule.c (init_psycopg): initialise the Xid object type. * psycopg/xid.h: * psycopg/xid_type.c: Implement a basic transaction ID object for use in two phase commit. 2008-05-12 James Henstridge * beginnings of a TPC test harness 2010-10-05 Daniele Varrazzo * psycopg/cursor_type.c: Common code in execute() and mogrify() merged. * psycopg/cursor_type.c: cursor.mogrify() accepts unicode queries. 2010-09-23 Daniele Varrazzo * lib/errorcodes.py: Added PostgreSQL 9.0 error codes. 2010-08-05 Daniele Varrazzo * psycopg/connection_int.c: don't execute a ROLLBACK on close()/GC. The command wasn't sent since 2.2.0 due to a bug, but after a ML discussion this behaviour proved more correct so the bug has become a feature. 2010-07-18 Federico Di Gregorio * Release 2.2.2. 2010-07-09 Daniele Varrazzo * psycopg/cursor_type.c: executemany() propagates exceptions raised by the iterable to the caller. * lib/pool.py: dropped logging.basicConfig() call. It messes up with projects using logging but where no handler is installed on the root logger. Bug reported by Joe Abbate. * psycopg/cursor_type.c: exceptions raised in the columns iterator of the copy methods propagated to the caller. 2010-05-20 Daniele Varrazzo * psycopg/typecast_datetime.c: Round seconds in historical timezones to the nearest minute. * lib/extras.py: register_tstz_w_secs() is now no-op. 2010-05-17 Federico Di Gregorio * Release 2.2.1. * Builds again on Windows. 2010-05-16 Federico Di Gregorio * Release 2.2.0. 2010-05-15 Federico Di Gregorio * typecast.c: Fixed problem related to receiving None from Python when a string was expected. 2010-05-07 Daniele Varrazzo * psycopg/adapter_datetime.c: Fixed TimestampFromTicks for second values > 59.5.

This fixes both a test failure and a segfault. 2010-02-15 Federico Di Gregorio * Added new Decimal adapter that correctly converts NaN and infinity to PostgreSQL NaN numeric values. Also added tests. 2010-02-15 Daniele Varrazzo * lib/errorcodes.py: Updated to PostgreSQL 8.4; added lookup() function. 2010-02-12 Daniele Varrazzo * 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 * 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 * License migration: psycopg2 is now LGPL3 + OpenSSL exception. * TODO file was never updated so lets remove it. 2010-02-10 Federico Di Gregorio * lib/extras.py: fixed register_tstz_w_secs() error as reported by Karsten Hilbert. 2009-11-25 Federico Di Gregorio * 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 * psycopg/adapter_pfloat.c: applied patch from Remy Blankto fix float loss of precision. 2009-10-04 Federico Di Gregorio * Release 2.0.13. * setup.py: applied patch from Christian Jacobsen to link to static version of libpq. * lib/extras.py: added support for UUID arrays. * psycopg/connection_int.c: applied patch from Richard Davies to avoid deadlocks with multiple threads using the same connection. 2009-08-08 Federico Di Gregorio * Release 2.0.12. * psycopg/lobject_int.c: fixed problem with writing large data using 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 * Applied patch from Robert Munro to fix version check in ZPsycopgDA. 2009-05-10 Federico Di Gregorio * Release 2.0.11. * lib/extras.py: fixed crash in fetchone() when prefetching using a RealDictCursor. * psycopg/cursor_ext.c: now raise correct exception when fetching using a custom row factory results in an error. * lib/extras.py: applied DictRow "diet" patch from Marko Kreen. 2009-04-21 Federico Di Gregorio * setup.py: applied patch from Elvis Pranskevichus to make PostgreSQL version detection more robust. 2009-04-20 Federico Di Gregorio * Release 2.0.10. * 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. 2009-04-19 Federico Di Gregorio * 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 * 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 * 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 * 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 * 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 * psycopg/config.h: added check to provide compatible isinf() for Solaris (thanks to Jeremy Mason.) 2009-02-23 Federico Di Gregorio * Release 2.0.9. 2009-02-17 James Henstridge * 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 * FreeBSD now has round(). Modified config.h as suggested by Jeroen Ruigrok van der Werven. 2009-02-06 Federico Di Gregorio * 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 * 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 * Fixed problem reported by Lawrence Oluyede where register_type() didn't work on connection and cursors suclasses. 2009-01-10 Federico Di Gregorio * psycopg/cursor_type.c: cursor.isready() now raise an exception when the libpq PQconsumeInput() call fails. 2008-12-04 Federico Di Gregorio * 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 * 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 * lib/extras.py: added inet support and related tests. 2008-09-23 James Henstridge * psycopg/psycopg.h (NotSupportedError_doc): clean up spelling/grammar a bit, using exception description from the PEP. 2008-09-23 Federico Di Gregorio * Applied patch from Brian Sutherland that fixes NULL valus in UUID support. 2008-09-19 Federico Di Gregorio * lib/extras.py: added UUID support, modeled after the code sent by Brian Sutherland. 2008-09-16 Federico Di Gregorio * Release 2.0.8. 2008-07-26 Federico Di Gregorio * psycopg/connection_type.c: merged get_backend_pid() method by Casey Duncan. 2008-07-23 James Henstridge * 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 * 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 * 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 * 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 * setup.py: fixed problem with spaces in pg_config path. 2008-05-27 Federico Di Gregorio * 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 * psycopg/cursor_type.c: fixed memory leak in .executemany(); on error "iter" was not dec'reffed. 2008-05-06 James Henstridge * 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 * psycopg/lobject.h: don't export the lobjectType symbol. 2008-05-05 Federico Di Gregorio * Fixed sun build problem by adding "sun" to config.h checks. 2008-05-05 James Henstridge * 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 * 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 * 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 * 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 * Release 2.0.7. 2008-03-31 James Henstridge * 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 * 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 * psycopg/connection_int.c (conn_notice_callback): don't leak notice messages. 2008-03-17 Federico Di Gregorio * 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 * 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 * 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 * psycopg/pqpath.c (_pq_fetch_tuples): Don't call Python APIs without holding the GIL. 2008-02-27 James Henstridge * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * Applied win32 patch from Jason Erickson. * Applied patch from Thomas Lotze to use correct version for new Zopes. 2007-12-20 James Henstridge * 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 * 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 * Use escape string syntax for string escape if connected to a server requiring it. 2007-11-09 Daniele Varrazzo * 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 * Fixed bug #192 (Decimal support not safe for use with multiple sub interpreters) as proposed by Graham Dumpleton. 2007-09-08 Federico Di Gregorio * Added MonoDevelop project, yahi! 2007-09-06 Federico Di Gregorio * Fixed bug #194. 2007-09-01 Federico Di Gregorio * Added "name" parameter to all .cursor() calls in extras.py. 2007-05-29 Federico Di Gregorio * 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 * 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 * 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 * 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 * Applied patch from Jason Erickson to fix win32 build glitches. 2007-04-11 Federico Di Gregorio * 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 * 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 * Added support for per-connection and per-cursor typecasters. 2007-02-11 Federico Di Gregorio * 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 * Release 2.0.6b1. * Added encodings patch from Karsten Hilbert. 2007-01-19 Federico Di Gregorio * 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 * 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 * Applied patch from Jason Erickson to make psycopg build again on win32 (closes: #132). 2006-09-30 Federico Di Gregorio * 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 * 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 * Fixed syntax error in lib/extras.py (see #123) 2006-09-02 Federico Di Gregorio * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * Applied better PostgreSQL patch from AA. 2006-05-24 Federico Di Gregorio * 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 * setup.py: fixed little problem with mx_include_dir as suggested by kvc (this closes #102). 2006-04-24 Federico Di Gregorio * 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 * lib/extras.py: added .next() to DictCursot to support iteration. 2006-03-02 Federico Di Gregorio * psycopg/typecast_array.c (typecast_array_tokenize): removed cast to build without warnings on 64 bit arches. 2006-02-11 Federico Di Gregorio * Release 2.0 beta 8. * psycopg/config.h: applied patch from Jason to fix handle leak on win32, as documented in #92. 2006-02-11 Federico Di Gregorio * Release 2.0 beta 7. * 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 * 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 * setup.py: libpq.dll not used anymore. win32 setup uses pg_config too. 2006-01-05 Federico Di Gregorio * 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 * 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 * 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 * 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 * lib/extras.py: added .callproc() to DictCursor as suggested by Philip Semanchuk. 2005-11-29 Federico Di Gregorio * MANIFEST.in: added docs/async.txt. (Closes: #75) 2005-11-26 Daniele Varrazzo * psycopg/psycopgmodule.c: fixed exceptions refcount. * Fixed lots of doctrings and added Epydoc-generated docs support. 2005-11-24 Federico Di Gregorio * 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 * psycopg/typecast.c: fixed problem with microseconds conversion by applying slightly modified patch from Ronnie Mackay. 2005-11-19 Federico Di Gregorio * 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 * ZPsycopgDA/pool.py: fixed connections leak by using the new name (PersistentConnectionPool) for the old connection pool class. 2005-11-16 Federico Di Gregorio * 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 * 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 * 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 * 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 * 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 * Applied patch from Daniele Varazzo to enable Decimal on Python 2.3 when the module is available (run-time check, nice.) 2005-10-26 Federico Di Gregorio * setup.cfg: added include_dirs line for SUSE 9.3. 2005-10-22 Federico Di Gregorio * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * lib/pool.py: applied patch from piro to avoid the scan of the whole connection array on getconn(). 2005-09-12 Federico Di Gregorio * 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 * 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 * 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 * psycopg/config.h: added __sun__ to the symbols checked for round() 2005-07-21 Federico Di Gregorio * 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 * 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 * 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 * setup.cfg: some clarifications and include_dirs example for Mandrake. * ZPsycopgDA/DA.py: DTMLFile -> HTMLFile everywhere to fix zope 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 * 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 * psycopg/cursor_type.c (_psyco_curs_execute): fixed segfault when not passing string or unicode to .execute(). 2005-06-01 Federico Di Gregorio * 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 * 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, * tests/types_basic.py: fixed float and binary tests. 2005-05-26 Federico Di Gregorio * Release 2.0b3. * ZPsycopgDA/db.py (DB.convert_description): isolated description conversion (and fixed the conversion as per #18). * ZPsycopgDA/DA.py: fixed again; this time Zope should work for real. :/ Also fixed the type-casters (psycopg 2 added the extra cursor parameter) as reported in #18. * psycopg/psycopgmodule.c (init_psycopg): fixed Python 2.2 build. 2005-05-19 Federico Di Gregorio * Release 2.0b2. * lib/extras.py (DictRow): Some extra methods for DictRow. * psycopg/cursor_type.c (_psyco_curs_execute): added explict check to avoid using None as bound variables (very importand for cursor subclasses calling cursor.execute(self, query, None). 2005-05-18 Federico Di Gregorio * 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 * psycopg/microprotocols.c (microprotocols_adapt): fixed memory leak on None as suggested by gh (closes: #16). 2005-05-10 Federico Di Gregorio * 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 * Release 2.0 beta 1. * psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): fixed a typo (pyDateTimeModuleP->pyDateTimeTypeP) that was causing errors with infinite datetime values. * psycopg/adapter_binary.c (binary_str): Py_XINCREF on the buffer that can be NULL on error. * psycopg/typecast_binary.*: applied slightly modified chunk/buffer object patch to allow round-trip of buffer objects (BYTEA columns.) * psycopg/cursor_type.c (psyco_curs_executemany): applied slightly fixed patch from wrobell to allow iterators in .executemany(). 2005-04-18 Federico Di Gregorio * MANIFEST.in: included debian directory. 2005-04-10 Federico Di Gregorio * psycopg/adapter_list.*: added list adapter. * psycopg/microprotocols.c (microprotocol_getquoted): moved _mogrify_getquoted into utility function in the microprotocols library. * setup.py: Added extensive error message on missing datetime headers. * Applied mingw patch from Daniele Varazzo. 2005-04-03 Federico Di Gregorio * lib/psycopg1.py (connection.autocommit): added compatibility .autocommit() method. * psycopg/psycopgmodule.c (psyco_connect): factory -> connection_factory. * lib/psycopg1.py: added psycopg 1.1.x compatibility module. 2005-03-29 Federico Di Gregorio * Applied patch to fix tuple count. * psycopg/pqpath.c (pq_is_busy): Staring from bug report from Jason Erickson fixed segfaults due to calling Python function without holding the GIL. 2005-03-24 Federico Di Gregorio * psycopg/adapter_binary.c (binary_escape): propagated Andrea's fix to binary adapter. * psycopg/adapter_qstring.c (qstring_quote): applied patch from Andrea Arcangeli to fix allocation failures (>4Gb) on 64 bit arches. * psycopg/typecast_array.c (typecast_array_tokenize): much better tokenization code. 2005-03-23 Federico Di Gregorio * psycopg/typecast_basic.c: all the basic casters now respect the 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 * 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 * lib/extensions.py: Added AsIs import. 2005-03-12 Federico Di Gregorio * psycopg/cursor.h: removed "qattr", not used anymore and added "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(). * 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 * Release 1.99.12.1. * psycopg/adapter_asis.c (asis_str): changed call to PyObject_Repr to PyObject_Str to avoid problems with long integers. 2005-03-03 Federico Di Gregorio * 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 * 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 * 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 * 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 * examples/myfirstrecipe.py: fixed adapter registration. 2005-2-7 Federico Di Gregorio * setup.py: added patch by Valentino Volonghi to build on MacOS X. 2005-01-29 Federico Di Gregorio * 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 * lib/extensions.py (register_adapter): added register_adapter function, exported ISQLQuote in psycopg.extensions. 2005-01-18 Federico Di Gregorio * 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 * 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 * Added debian directory (thanks to W. Borgert who sent initial patch based on cdbs.) 2004-12-20 Federico Di Gregorio * 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 * 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 * 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 * psycopg/cursor_type.c (_mogrify): ported %% fix from 1.1.15. 2004-11-20 Federico Di Gregorio * psycopg/cursor_type.c (psyco_curs_execute): added check to raise an exception if a cursor tries to .execute() while an async query is already in execution froma different cursor. 2004-11-20 Federico Di Gregorio * psycopg/connection_type.c (psyco_conn_cursor): renamed 'cursor' argument to 'cursor_factory'. 2004-11-19 Federico Di Gregorio * 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 * 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 * 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 * psycopg/cursor_type.c (cursor_dealloc): fixed small memory leak due to missing disposal of self->pgres. 2004-9-14 Federico Di Gregorio * examples/dialtone.py: Added adapt() example by Valentino Volonghi. 2004-09-14 Federico Di Gregorio * 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 * psycopg/cursor_type.c (_mogrify): and qattr is gone. 2004-09-05 Federico Di Gregorio * 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 * psycopg/pqpath.c (_pq_fetch_tuples): ported rowcount fix from 1.1.15. * ZPsycopgDA/*: ZPsycopgDA back in action, using the new pooling code. 2004-08-29 Federico Di Gregorio * psycopg/typecast_basic.c (typecast_DECIMAL_cast): added DECIMAL typecaster; it even works :). * scripts/buildtypes.py (basic_types): added DECIMAL typecaster for the NUMERIC oid. * examples/threads.py: updated threads example to use pooling code. * lib/pool.py: added very simple and thread-safe connection pooling class. * psycopg/cursor_type.c (psyco_curs_fetchmany): fixed problem with .fetchall() and .fetchmany() returning None instead of [] on empty result sets. * Release 1.99.8. 2004-08-28 Federico Di Gregorio * 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 * psycopg/cursor_type.c (_psyco_curs_prefetch): added check for asynchronous fetch by wrong cursor. * psycopg/pqpath.c (pq_fetch): fixed backend status message (bug reported by Daniele Varrazzo.) 2004-07-29 Federico Di Gregorio * 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 * 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 * psycopg/typecast_datetime.c (typecast_PYINTERVAL_cast): replaced round() with micro() when rounding seconds (fixes bugs reported by Daniele Varrazzo.) 2004-07-16 Federico Di Gregorio * 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 to be closed (used to not close it during COPY FROM/TO criticals.) * psycopg/cursor_type.c (psyco_curs_fileno, psyco_curs_isready): added extension methods related to async queries. 2004-07-15 Federico Di Gregorio * 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. * psycopg/typecast.c (typecast_call): changed typecast call code to take the additional cursor parameter, needed for cursor-dependent type casting (tzinfo & friends.) * psycopg/cursor_type.c (_psyco_curs_buildrow_with_factory): added use of tuple factories to fetcXXX methods. * lib/extras.py: little extra goodies for psycopg. 2004-07-14 Federico Di Gregorio * Release 1.99.6. * psycopg/connection_type.c: added .dsn attribute to connection objects. * psycopg/cursor_type.c (psyco_curs_mogrify): added .mogrify() method. * psycopg/adapter_qstring.c: copy the connection encoding only if wrapped object is unicode and added table of encodings. 2004-07-13 Federico Di Gregorio * psycopg/cursor_type.c (_mogrify): moved Dprintf statement to 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. (cursorObject_members): and we finally export the saved query 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 * psycopg/typecast_datetime.c: ported interval fix from 1.1.x. 2004-05-16 Federico Di Gregorio * psycopg/typecast_datetime.c (typecast_*_cast): fixed Value error when seconds > 59 by setting minutes += 1 and seconds -= 60 (reported by Marcel Gsteiger.) 2004-04-24 Federico Di Gregorio * ported time interval patch by Ross Cohen from 1.1.12. 2004-04-19 Federico Di Gregorio * psycopg/typecast_datetime.c (typecast_PYDATE_cast): applied patch from Jason Erickson: min and max taken from datetime.Date type. 2004-04-18 Federico Di Gregorio * 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 * setup.py: Various changes. The critical ones: - Make an empty pthread.h file so all the code doing an #include will find something. - Appended the winsock2 library and the PostgreSQL library to the library path. - Setup the include path. - Have the PSYCOPG_VERSION macro be included with quotes. * config.h: Added/Cleaned up Win32 includes, defines, stub functions. * typecast.h: Removed ';' after PyObject_HEAD in the typecastObject structure since Microsoft Visual Studio does not like it. 2004-04-15 Federico Di Gregorio * Release 1.99.5 (bug-fixing and reorganization) * setup.py et al.: moved psycopg to psycopg._psycopg to make easier to provide high level python-only utilities (like the promised pooling code). psycopg/__init__.py imports _psycopg and make all the default DBAPI-2.0 stuff available. 2004-04-14 Federico Di Gregorio * psycopg/psycopgmodule.c (initpsycopg): wrapped initialization of date/time adapters in #ifdefs to have psycopg compile without mx or builtin datetime. 2004-04-10 Federico Di Gregorio * Release 1.99.4. 2004-04-09 Federico Di Gregorio * psycopg/typecast_builtins.c: changed DATE to not include DATETIME types anymore. * psycopg/adapter_datetime.c (pydatetime_str): switched from strftime to isoformat to preserve fractional seconds. 2004-04-08 Federico Di Gregorio * psycopg/psycopgmodule.c (psyco_connect): ported sslmode parameter from 1.1 branch. * psycopg/adapter_datetime.*: added python built-in datetime adapters. also added the datetime typecasters (still using mx as default). * psycopg/typecast.h: removed aliases, they now live in the right typecast_xxx.c file. 2004-03-08 Federico Di Gregorio * Release 1.99.3 (alpha 4). * examples/lastrowid.py: and the .lastrowid example is in. * psycopg/cursor_type.c (_mogrify): added call to .prepare() method in both dict and sequence path. * psycopg/connection_int.c (conn_set_client_encoding): added encoding-change code. * psycopg/adapter_qstring.c (qstring_quote): added hard-coded support for utf8 and latin1 encodings. 2004-03-01 Federico Di Gregorio * 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 * Release 1.99.2 (alpha 3). * psycopg/cursor_type.c: added .rownumber and .connection attributes.
