incompatibilities. Here are the major changes.
- Dropped support for Python below 2.3 and PostgreSQL below 7.4.
- Improved performance of fetchall() for large result sets
by speeding up the type casts (as suggested by Peter Schuller).
- Exposed exceptions as attributes of the connection object.
- Exposed connection as attribute of the cursor object.
- Cursors now support the iteration protocol.
- Added new method to get parameter settings.
- Added customizable row_factory as suggested by Simon Pamies.
- Separated between mandatory and additional type objects.
- Added keyword args to insert, update and delete methods.
- Added exception handling for direct copy.
- Release the GIL while making a connection
(as suggested by Peter Schuller).
- If available, use decimal.Decimal for numeric types.
- Allow DB wrapper to be used with DB-API 2 connections
(as suggested by Chris Hilton).
- Made private attributes of DB wrapper accessible.
- Dropped dependence on mx.DateTime module.
- Support for PQescapeStringConn() and PQescapeByteaConn();
these are now also used by the internal _quote() functions.
- Added 'int8' to INTEGER types. New SMALLINT type.
- Added a way to find the number of rows affected by a query()
with the classic pg module by returning it as a string.
For single inserts, query() still returns the oid as an integer.
The pgdb module already provides the "rowcount" cursor attribute
for the same purpose.
- Improved getnotify() by calling PQconsumeInput() instead of
submitting an empty command.
- Removed compatibility code for old OID munging style.
- The insert() and update() methods now use the "returning" clause
if possible to get all changed values, and they also check in advance
whether a subsequent select is possible, so that ongoing transactions
won't break if there is no select privilege.
- Added "protocol_version" and "server_version" attributes.
- Revived the "user" attribute.
- The pg module now works correctly with composite primary keys;
these are represented as frozensets.
- Removed the undocumented and actually unnecessary "view" parameter
from the get() method.
- get() raises a nicer ProgrammingError instead of a KeyError
if no primary key was found.
- delete() now also works based on the primary key if no oid available
and returns whether the row existed or not.

Mostly bug fixes from 3.8.
- Use string methods instead of deprecated string functions.
- Only use SQL-standard way of escaping quotes.
- Added the functions escape_string() and escape/unescape_bytea()
(as suggested by Charlie Dyson and Kavous Bojnourdi a long time ago).
- Reverted code in clear() method that set date to current.
- Added code for backwards compatibility in OID munging code.
- Reorder attnames tests so that "interval" is checked for before "int."
- If caller supplies key dictionary, make sure that all has a namespace.

The only change is to fix the handling of primary keys when using namespaces.

so recent.

Most important change was serious bug in 3.5 that did not allow DB-API 2.0
version to work without a manual change.
Other changes:
- Better DB-API 2.0 compliance
- Exception hierarchy moved into C module and made available to both APIs
- Fix error in update method that caused false exceptions
- Moved to standard exception hierarchy in classic API
- Added new method to get transaction state
- Use proper Python constants where appropriate
- Use Python versions of strtol, etc. Allows WIN32 build
- Bug fixes and cleanups

PostgreSQL tree and I have released this version that is no longer tied
to a specific version of PostgreSQL.
|
|
Remove files and patches in the py-postgresql directory and add necessary
ones in the postgresql directory.
|
|
this package build standalone. py-postgresql uses it's own version
numbering and really doesn't have much to do with the rest of the
postgresql packages.
|
|
adds a few minor features and makes a few speedups in the code, plus:
- Fix some DB-API quoting problems (niall.smart@ebeon.com)
- Moved development into PostgreSQL development tree.
|
|
|
|
+ move the patch digest/checksum values from files/patch-sum to distinfo
+ include distfile filesizes in distinfo
|
