PostgreSQL database adapter for the Python programming language
d190d5918a
* psycopg/pqpath.c (pq_execute_command_locked): add an error argument to hold an error when no PGresult is returned by PQexec, rather than using pq_set_critical(). (pq_complete_error): new function that converts the error returned by pq_execute_command_locked() to a Python exception. (pq_begin_locked): add error argument. (pq_commit): use pq_complete_error(). (pq_abort): use pq_complete_error(). (pq_abort_locked): always call pq_set_critical() on error, and clear the error message from pq_execute_command_locked(). (pq_execute): use pq_complete_error() to handle the error from pq_begin_locked(). * psycopg/pqpath.c (pq_begin): remove unused function. * psycopg/connection_type.c (psyco_conn_commit): if conn_commit() raises an error, just return NULL, since it is now setting an exception itself. (psyco_conn_rollback): same here. * psycopg/connection_int.c (conn_commit): don't drop GIL and lock connection before calling pq_commit(). (conn_rollback): same here. (conn_close): use pq_abort_locked(). (conn_switch_isolation_level): same here. (conn_set_client_encoding): same here. * psycopg/pqpath.h: add prototype for pq_abort_locked(). * psycopg/pqpath.c (pq_commit): convert function to run with GIL held, and handle errors appropriately. (pq_abort): same here. (pq_abort_locked): new function to abort a locked connection. 2007-12-22 James Henstridge <james@jamesh.id.au> * psycopg/pqpath.c (pq_raise): add a "pgres" argument so we can generate nice errors not related to a particular cursor. (pq_execute): use pq_begin_locked() rather than pq_begin(). Use pq_raise() to handle any errors from it. * psycopg/pqpath.c (pq_execute_command_locked): helper function used to execute a command-style query on a locked connection. (pq_begin_locked): a variant of pq_begin() that uses pq_execute_command_locked(). (pq_begin): rewrite to use pq_begin_locked(). |

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.
