PostgreSQL database adapter for the Python programming language
f64cbeda46
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. |

psycopg - Python-PostgreSQL Database Adapter
********************************************
psycopg is a PostgreSQL database adapter for the Python programming
language. This is version 2, a complete rewrite of the original code to
provide new-style classes for connection and cursor objects and other
sweet candies. Like the original, psycopg 2 was written with the aim of
being very small and fast, and stable as a rock.
psycopg is different from the other database adapter because it was
designed for heavily multi-threaded applications that create and destroy
lots of cursors and make a conspicuous number of concurrent INSERTs or
UPDATEs. psycopg 2 also provide full asycronous operations for the really
brave programmer.
There are confirmed reports of psycopg 1.x compiling and running on Linux
and FreeBSD on i386, Solaris, MacOS X and win32 architectures. psycopg 2
does not introduce build-wise incompatible changes so it should be able to
compile on all architectures just as its predecessor did.
Now go read the INSTALL file. More information about psycopg extensions to
the DBAPI-2.0 is available in the files located in the doc/ direcory.
psycopg is free software ("free as in freedom" but I like beer too.)
Licensing information is available in the LICENSE file.
Contributors
------------
A short list of contributors to psycopg2 follows (if you feel you belong
to this list and you can't find yourself here just drop me a mail):
* Kudos to piro for all the documentation work.
* Peter Fein contributed a logging connection/cursor class that even if it
was not used directly heavily influenced the implementation currently in
psycopg2.extras.
