the latest version and I wanted to make sure that there was a clean release. I also change the build files as I discussed in my letter of Nov 6, 2001. At the time I was asked to hold off until after the release.

Announce: Release of PyGreSQL version 3.3
|
|
=========================================
|
|
|
|
PyGreSQL v3.3 has been released.
|
|
It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL.tgz. If
|
|
you are running NetBSD, look in the packages directory under databases.
|
|
There is also a package in the FreeBSD ports collection.
|
|
|
|
From March 1 2001 the PyGreSQL development has moved into the PostgreSQL
|
|
development tree.
|
|
|
|
PostgreSQL is a database system derived from Postgres4.2. It conforms
|
|
to (most of) ANSI SQL and offers many interesting capabilities (C
|
|
dynamic linking for functions or type definition, etc.). This package
|
|
is copyright by the Regents of the University of California, and is
|
|
freely distributable.
|
|
|
|
Python is an interpreted programming language. It is object oriented,
|
|
simple to use (light syntax, simple and straightforward statements), and
|
|
has many extensions for building GUIs, interfacing with WWW, etc. An
|
|
intelligent web browser (HotJava like) is currently under development
|
|
(November 1995), and this should open programmers many doors. Python is
|
|
copyrighted by Stichting S Mathematisch Centrum, Amsterdam, The
|
|
Netherlands, and is freely distributable.
|
|
|
|
PyGreSQL is a python module that interfaces to a PostgreSQL database. It
|
|
embeds the PostgreSQL query library to allow easy use of the powerful
|
|
PostgreSQL features from a Python script.
|
|
|
|
This release fixes a few bugs, adds a few minor features and makes a
|
|
few speedups in the code.
|
|
|
|
The next release (unless serious bugs are found) will be to match PyGreSQL
|
|
to version 2.0 of Python.
|
|
|
|
See the other changes below or in the Changelog file.
|
|
|
|
PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system. It
|
|
is based on the PyGres95 code written by Pascal Andre,
|
|
andre@chimay.via.ecp.fr. I changed the version to 2.0 and updated the
|
|
code for Python 1.5 and PostgreSQL 6.2.1. While I was at it I upgraded
|
|
the code to use full ANSI style prototypes and changed the order of
|
|
arguments to connect. Later versions are fixes and enhancements to that.
|
|
The latest version of PyGreSQL works with Python 1.5.2 and PostgreSQL 7.0.x
|
|
|
|
Important changes from PyGreSQL 3.2 to PyGreSQL 3.3
|
|
- Added NUMERICOID to list of returned types. This fixes a bug when
|
|
returning aggregates in the latest version of PostgreSQL.
|
|
|
|
Important changes from PyGreSQL 3.1 to PyGreSQL 3.2
|
|
Note that there are very few changes to PostgreSQL between 3.1 and
|
|
3.2. The main reason for the release is the move into the PostgreSQL
|
|
development tree. Even the WIN32 changes are pretty minor.
|
|
- Add WIN32 support (gerhard@bigfoot.de)
|
|
- Fix some DB-API quoting problems (niall.smart@ebeon.com)
|
|
- Moved development into PostgreSQL development tree.
|
|
|
|
Important changes from PyGreSQL 3.0 to PyGreSQL 3.1
|
|
- Fix some quoting functions. In particular handle NULLs better.
|
|
- Use a method to add primary key information rather than direct
|
|
manipulation of the class structures.
|
|
- Break decimal out in _quote (in pg.py) and treat it as float.
|
|
- Treat timestamp like date for quoting purposes.
|
|
- Remove a redundant SELECT from the get method speeding it, and insert
|
|
since it calls get, up a little.
|
|
- Add test for BOOL type in typecast method to pgdbTypeCache class.
|
|
(tv@beamnet.de)
|
|
- Fix pgdb.py to send port as integer to lower level function
|
|
(dildog@l0pht.com)
|
|
- Change pg.py to speed up some operations
|
|
- Allow updates on tables with no primary keys.
|
|
|
|
Important changes from PyGreSQL 2.4 to PyGreSQL 3.0:
|
|
- Remove strlen() call from pglarge_write() and get size from object.
|
|
(Richard@Bouska.cz)

|
|
will cause backwards compatibility issues.)

|
|
- Change hash-bang lines to use /usr/bin/env
|
|
- Clearing date should be blank (NULL) not TODAY

|
tony@printra.net, jeremy@alum.mit.edu and others to get the final
|
|
version ready to release.
|
|
|
|
Important changes from PyGreSQL 2.3 to PyGreSQL 2.4:
|
