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.
* 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.
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().
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.
* 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.
(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.
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.
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.
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.
* 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.
(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.
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.
