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

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

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

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.

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.

(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.
