Building without extensions has been long broken and nobody really cares
about a pure-DBAPI implementation (which could be created using a wrapper
instead).
It has long been used in wrong ways, with the function receiving a
connection or lobject instead of a cursor. It has always been unnoticed
(nobody has noticed the wrong object attached to the exception in the
wrong cases) but it started crashing the interpreter with Python 3.2 on
Windows.
Thanks to Jason Erickson for finding the problem and helping fixing it.
(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.
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.
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.
interpreters) as proposed by Graham Dumpleton.
If running in the main interpreter, use a cached version of the Decimal
object. Else repeat the object lookup.
