# USE OR PERFORMANCE OF THIS SOFTWARE. |
#=======================================================================|
# Revision History: |
# |
# Date Ini Description |
# --------- --- ------------------------------------------------------- |
# 30NOV2002 bga Updated tests for PostgreSQL 7.3. |
# 10NOV2002 bga Added an additional PgNumeric class check. |
# 27OCT2002 gh Don't check for the obsolete displaysize field in |
# cursor.description. Also don't check the backend enco- |
# ding. |
# 08SEP2002 gh Added tests for PgResultSet. |
# 11AUG2002 bga Added additional tests for the PgNumeric class. |
# 03AUG2002 gh Added test for bug #589370 (wether it is possible to |
# use OID in a query that doesn't return any rows). |
# 29JUL2002 gh Added a few tests for PgNumeric (which currently fail). |
# Simplified the construction of testcases by a lot and |
# fixed a bug where there were two methods named |
# CheckConnectionObject (thus hiding the first one). |
# 16APR2002 gh Updated the PostgreSQL version specific tests to cope |
# with PostgreSQL 7.2.x. |
# 09SEP2001 bga Modified tests to reflect changes to PgVersion object. |
# In particulare, a PgVersion object no longer has a |
# __dict__ attribute, but now acts as a mapping object. |
# The coerce method of the PgVersion object will always |
# succeed, but will return a 'special' PgVersion Object |
# that contains any error information if the coersion |
# failed. |
# 08SEP2001 gh Added more tests for PgVersion object. |
# 03SEP2001 gh Added more checks for PgMoney methods. |
# 29JUL2001 bga Added test to check for correct handling of non-print- |
# able characters in the CHAR types. |
# 12JUN2001 bga Added more tests relating to closed Connection and |
# Cursor objects. Also added test for corrected circular |
# references with weak references (Python 2.1+ only). |
# 10JUN2001 bga Modified tests to reflect changes to PgSQL.py. |
# 09JUN2001 bga Fixed test cases to reflect corrected implementation of |
# the PgInt2 and PgInt8 pow() function. |
# 04JUN2001 bga Fixed a reversed assertion in the CheckPgVer test. |
# 03JUN2001 bga Modified test to account for the new C implementations |
# of PgInt2 and PgInt8. |
# 27MAY2001 bga Expanded the number of tests. Primarily, added tests |
# to check out the emulated numerical types, PgInt8, |
# PgInt2, and PgMoney. |
# 21MAY2001 bga Changed assert's to use the unittest assert_() method. |
# --- Discovered and fixed some really nasty bugs. |
# 18APR2001 bga Changed version check so that 7.1<anything> is treated |
# as version 7.1. |
# 09MAR2001 bga Added version check for PostgreSQL 7.1beta. |
# Added tests to check the 'pyformat' paramstyle. |
# 13DEC2000 bga Added version check for PostgreSQL 7.0.3. |
# 09OCT2000 bga Fixed another section for v6.5.x compatability. |
# 08OCT2000 bga Added code to check for the PostgreSQL version and mod- |
# ify the test(s) accordingly. |
# 01OCT2000 bga Initial release by Billy G. Allie. |
