Raw Blame History

2005-04-10 Federico Di Gregorio <fog@debian.org>
* 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 <fog@debian.org>
* 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 <fog@debian.org>
* 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 <fog@debian.org>
* 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 <fog@debian.org>
* 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 <fog@debian.org>
* psycopg/typecast_array.c: added some more structure to implement
array typecasting.
* scripts/buildtypes.py: new version to include array data.
2005-03-15 Federico Di Gregorio <fog@debian.org>
* lib/extensions.py: Added AsIs import.
2005-03-12 Federico Di Gregorio <fog@debian.org>
* 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 <fog@initd.org>
* 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 <fog@debian.org>
* psycopg/typecast.h: added array casting functions.
* scripts/maketypes.sh: does not generate pgversion.h anymore.
* Updated all examples for the release.
2005-03-02 Federico Di Gregorio <fog@debian.org>
* Release 1.99.12.
* psycopg/adapter_*.c: added __conform__ to all adapters.
* psycopg/adapter_qstring.c (qstring_quote): we now use
PyString_AsStringAndSize() instead of strlen() that would stop at
the first embedded \0 (but note that libpq quoting function will
truncate the string anyway!)
* COPY TO implemented using both old and new (v3) protocol.
* psycopg/pqpath.c (_pq_copy_out_v3): implemented and working.
* psycopg/cursor_type.c (psyco_curs_copy_to): added cursor object
interface for copy_to.
* COPY FROM implemented using both old and new (v3) protocol.
* psycopg/config.h (Dprintf): declaration for asprintf is gone.
* psycopg/pqpath.c (_pq_copy_in_v3): implemented.
2005-03-01 Federico Di Gregorio <fog@debian.org>
* setup.py: now we generate a slighly more verbose version string
that embeds some of the compile options, to facilitate users' bug
reports.
* psycopg/cursor_type.c (psyco_curs_copy_from): we now use
PyOS_snprintf instead of asprintf. On some platforms this can be
bad (win32).. if that's your case, get a better platform. :/
* psycopg/microprotocols.c (microprotocols_adapt): fixed small
typo that made adaptation using __conform__ impossible.
2005-02-28 Federico Di Gregorio <fog@debian.org>
* lib/extras.py: removed AsIs adapter (now a built-in); also
removed prepare() method from the adapters that don't use it to
avoid an extra method call at mogrification time.
* psycopg/psycopgmodule.c (psyco_adapters_init): added
initialization of the AsIs adapter (adapts int, long, float and
*wonder* None!)
* psycopg/cursor_type.c (_mogrify_getquoted): reorganized the code
to adapt and then call .getquoted() to obtain the quoted data into
this new function.
2005-2-27 Federico Di Gregorio <fog@initd.org>
* examples/myfirstrecipe.py: fixed adapter registration.
2005-2-7 Federico Di Gregorio <fog@initd.org>
* setup.py: added patch by Valentino Volonghi to build on MacOS X.
2005-01-29 Federico Di Gregorio <fog@debian.org>
* psycopg/pqpath.c (_pq_fetch_tuples): fixed scale-related
segfault (*fourth* mail from Andrea. Another couple like this and
psycopg 2 will exit alpha at warp speed.)
* psycopg/pqpath.c (pq_fetch): _pq_copy_out_3 -> _pq_copy_out_v3
(second and third mail from Andrea. :/)
* psycopg/cursor_type.c (_psyco_curs_has_write_check): added check
on .write() attribute, fixed compilation problems (first mail from
Andrea Arcangeli.)
2005-01-20 Federico Di Gregorio <fog@debian.org>
* lib/extensions.py (register_adapter): added register_adapter
function, exported ISQLQuote in psycopg.extensions.
2005-01-18 Federico Di Gregorio <fog@debian.org>
* psycopg/pqpath.c (_pq_fetch_tuples): ported scale/precision fix
from psycopg 1.1.
* LICENSE: detailed licensing information. Re-licensed some parts
under BSD-like to allow integration is pysqlite.
2005-01-13 Federico Di Gregorio <fog@debian.org>
* ZPsycopgDA/db.py (DB.query
): ported ZPsycopgDA connection fix
from psycopg 1.1.
* lib/*.py: added pydoc-friendly messages.
2005-01-12 Federico Di Gregorio <fog@debian.org>
* Added debian directory (thanks to W. Borgert who sent initial
patch based on cdbs.)
2004-12-20 Federico Di Gregorio <fog@debian.org>
* psycopg/pqpath.c (pq_execute): removed multiple calls to
pq_fetch in syncronous DBAPI compatibility mode to solve rowcount
problem.
2004-12-14 Federico Di Gregorio <fog@debian.org>
* Mm.. release 1.99.11.
* psycopg/cursor_type.c (_psyco_curs_prefetch): fixed bug in
interaction between the .isready() method and
_psyco_curs_prefetch: isready now store away the pgres but leave
prefetch do its work.
* psycopg/*.c: changed the names of most of the psycopg's built-in
types to replect their position in the psycopg._psycopg module.
2004-12-10 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c: now *all* write or async accesses to the
connection object are arbitrated using the connection lock.
* psycopg/cursor_type.c (psyco_curs_isready): now we reset the
current async cursor if it is ready, to allow other cursors to
.execute() without raising the "transaction in progress" error.
* psycopg/pqpath.c (pq_is_busy): gained status of high-level
function with its own blocking and locking.
* psycopg/cursor.h (EXC_IF_CURS_CLOSED): also checks the
connection (a closed connection implies a closed cursor.)
* psycopg/cursor_type.c: cursor's connection is correctly
INCREFfed and DECREFfed.
* psycopg/connection_type.c: removed the cursors list from the
connection object. It is not necessary anymore for the connection
to know about the cursors and the reference counting will keep the
connection alive (but possibly closed) until all cursors are
garbage collected.
2004-11-20 Federico Di Gregorio <fog@initd.org>
* psycopg/cursor_type.c (_mogrify): ported %% fix from 1.1.15.
2004-11-20 Federico Di Gregorio <fog@initd.org>

exception if a cursor tries to .execute() while an async query is
already in execution froma different cursor.
2004-11-20 Federico Di Gregorio <fog@debian.org>

argument to 'cursor_factory'.
2004-11-19 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c (_psyco_curs_buildrow_fill): now standard
tuples are filled using PyTuple_SET_ITEM while extended types
(created via row_factory) are filled using PySequence_SetItem.
* psycopg/cursor_type.c: changed cursor attribute name from
tuple_factory to row_factory.
2004-10-14 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c (_psyco_curs_buildrow_fill): now we use
PySequence_SetItem to avoid problems with containers created from
cursor's .tuple_factory attribute.
* lib/extras.py (DictCursor.execute): fixed stupid bug with cursor
setting self.tuplefactory instead of self.tuple_factory.
2004-10-02 Federico Di Gregorio <fog@debian.org>
* Release 1.99.10.
* psycopg/cursor_type.c (_psyco_curs_buildrow_*): unified normal
and factory code into the _psyco_curs_buildrow_fill function; no
more memory leaks here.
* psycopg/config.h (round): added check for __FreeBSD__ (that
should be defined when compiling with gcc, I hope.)
* setup.py: removed a lot of code now in setup.cfg.
2004-09-24 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c (cursor_dealloc): fixed small memory leak
due to missing disposal of self->pgres.
2004-9-14 Federico Di Gregorio <fog@initd.org>
* examples/dialtone.py: Added adapt() example by Valentino
Volonghi.
2004-09-14 Federico Di Gregorio <fog@debian.org>
* psycopg/microprotocols.c (microprotocols_adapt): lots of changes
to the microprotocols layer (it is not micro anymore);
implementing almost all the PEP 246. The adapter registry is now
indexed by (type, protocol) and not by type alone.
2004-09-13 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c (_mogrify): and qattr is gone.
2004-09-05 Federico Di Gregorio <fog@debian.org>
* Release 1.99.9 (or, the "twisting by the pool" release).
* psycopg/pqpath.c (_pq_fetch_tuples): changed to "static void"
instead of "static int", no ways for this function to fail.
2004-09-04 Federico Di Gregorio <fog@debian.org>
* psycopg/pqpath.c (_pq_fetch_tuples): ported rowcount fix from
1.1.15.
* ZPsycopgDA/*: ZPsycopgDA back in action, using the new pooling
code.
2004-08-29 Federico Di Gregorio <fog@debian.org>

.fetchall() and .fetchmany() returning None instead of [] on empty
result sets.
* Release 1.99.8.
2004-08-28 Federico Di Gregorio <fog@debian.org>

typecaster.
* lib/extensions.py: the encodings dictionary is not available by
default but can be accessed from the psycopg.extensions module.
* psycopg/adapter_qstring.h: remove encoding information from
qstring adapter and moved it into psycopg module.
2004-08-26 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c (_psyco_curs_prefetch): added check for
asynchronous fetch by wrong cursor.
* psycopg/pqpath.c (pq_fetch): fixed backend status message (bug
reported by Daniele Varrazzo.)
2004-07-29 Federico Di Gregorio <fog@debian.org>
* psycopg/typecast_basic.c (typecast_BINARY_cast): reverted to
using strings instead of buffers when converting postgresql binary
objects (should *temporarily* fix corruption bug reported on
win32.)
2004-07-21 Federico Di Gregorio <fog@debian.org>
* psycopg/cursor_type.c: removed __iter__ and next methods from
object methods and moved them where they do belong (tp_iter and
tp_iternext.) Bug reported by Daniele Varrazzo (again!)
2004-07-19 Federico Di Gregorio <fog@debian.org>
* psycopg/typecast_datetime.c (typecast_PYINTERVAL_cast): replaced
round() with micro() when rounding seconds (fixes bugs reported by

* psycopg/pqpath.c (pq_set_critical): allow for a custom message
insted of the one from PQerrorMessage.

objects.
* psycopg/cursor_type.c (psyco_curs_mogrify): added .mogrify()
method.

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

2004-04-19 Federico Di Gregorio <fog@debian.org>
* 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 <fog@debian.org>
* Applied changes from Jason Erickson to build on win32; see his
(slightly edited) entry below. (Still builds on Linux :)
* psycopg/*.c: removed inclusion of pthread.h from all files
except psycopg/config.h to build on win32 without faking the file.
2004-04-15 Jason Erickson <jerickso@stickpeople.com>
* setup.py: Various changes. The critical ones:
- Make an empty pthread.h file so all the code doing an
#include <pthread.h> will find something.
- Appended the winsock2 library and the PostgreSQL library to
the library path.
- Setup the include path.
- Have the PSYCOPG_VERSION macro be included with quotes.
* config.h: Added/Cleaned up Win32 includes, defines, stub functions.
* typecast.h: Removed ';' after PyObject_HEAD in the
typecastObject structure since Microsoft Visual Studio does not
like it.
2004-04-15 Federico Di Gregorio <fog@debian.org>
* 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.

* Release 1.99.4.
2004-04-09 Federico Di Gregorio <fog@debian.org>
* psycopg/typecast_builtins.c: changed DATE to not include
DATETIME types anymore.

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 <fog@debian.org>
* 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.

support for utf8 and latin1 encodings.
2004-03-01 Federico Di Gregorio <fog@debian.org>
* psycopg/connection_int.c (conn_close): does not use libpq
functions on NULL pgconn (this can happen when conn_close is
called after a failed PQconnect.)
2004-02-29 Federico Di Gregorio <fog@debian.org>
* Release 1.99.2 (alpha 3).
* psycopg/cursor_type.c: added .rownumber and .connection
attributes. Also added .scroll(), .next() and .__iter__() methods
(see DBAPI2-.0 extensions on PEP.)

added connection method .set_isolation_level(). Also added all
error objects to the connection (see DBAPI2-.0 extensions on PEP.)
* psycopg/connection_int.c (conn_switch_isolation_level): added
isolation level switching code.
* setup.py: removed all references to PSYCOPG_NEWSTYLE: support
for python < 2.2 has been dropped.
* typecast_basic.c (typecast_BINARY_cast): now binary objects are
returned as true buffers.
* adapter_binary.*: added adapter for buffers and binary (bytea)
objects.
* Release 1.99.1 (alpha 2).
* adapter_mxdatetime.*: added adapters for all mx.DateTime types.
2004-02-28 Federico Di Gregorio <fog@debian.org>
* cursor_type.c (_mogrify): complete rework of the mogrification
code to use the microprotocols_adapt function.
* typecast_basic.c (typecast_BOOLEAN_cast): we now return real
Py_True and Py_False values.
* microprotocols.h: added very simple microprotocols
implementation to allow for python->postgresql types registry.
2004-01-05 Federico Di Gregorio <fog@debian.org>
* connection_int.c (conn_commit/conn_rollback): added code to
commit/rollback and connection methods.
2004-01-04 Federico Di Gregorio <fog@debian.org>

2003-08-01 Federico Di Gregorio <fog@debian.org>
* cursor_type.c (_mogrify_sequence): added sequence mogrification,
can be done better, on the dict model.
2003-07-28 Federico Di Gregorio <fog@debian.org>
* typeobj_qstring.c: added quoted strings (can use both own code,
like psycopg 1.x or PQescapeString from lipq.)
2003-07-21 Federico Di Gregorio <fog@debian.org>
* connection_type.c (psyco_conn_close): added .close()
method. wow.
* cursor_*.c: added basic cursor interface (new-style.)
2003-07-20 Federico Di Gregorio <fog@debian.org>
* psycopg/*: beginning of new source layout. if you think this
changelog is somewhat empty, you're right. look at
doc/ChangeLog-1.x for psycopg 1.x changelog just before the
branch.
