a79a5292e7 Added support with cursors without scroll clause 
Using nothing is different from NO SCROLL, see DECLARE notes
in PG docs.

27421f1e41 Name can be passed as None to cursor() 
Makes invocation from subclasses and generic code easier.

Code simplified by using default values for keyword arguments
and avoiding needless conversions back and forth between Python and C
strings. Also added connection type check to cursor's init.

5fcbe7bd0f Check/set connection status at commit inside the critical section 
Failing to do so was causing the issue reported in ticket #103. The issue
as reported was fixed when SET ISOLATION LEVEL was dropped, but the real
problem wasn't fixed.

b8597dc1d3 Fixed NamedTupleCursor rownumber during iteration. 
The correction is similar to the other one for the other subclasses.

Also added tests for rowcount and rownumber during different fetch styles.

ebec522a07 Fixed rownumber for cursor subclasses during iterations 
Regression introduced to fix ticket #80. Don't use fetchmany to get the
chunks of values. I did it that way because I was ending up into infinite
recursion calling __iter__ from __iter__: the solution has been the
"while 1: yield next()" idiom.
 2012-02-23 22:55:13 +00:00
Daniele Varrazzo
7221ea9ec5 Added test to check rowcount behaves fine during named cursor iteration 
Actually *it doesn't*: once we iterate the first itersize records, rowcount
is reset to zero. If we want to fix it we need an extra member in the
cursor.

bca7200b3f Cache FixedOffsetTimezone instances 
Avoid creating new a new FixedOffsetTimezone instance if one with the
same offset and name has been created before. This will save memory
when returning many rows containing "timestamp with timezone" columns,
and also improves comparability.

1469a56512 Fixed repr for FixedOffsetTimezone for offsets west of UTC (negative) 
The offset displayed was always positive and somewhat confusing. The
offset displayed now is the offset that the instance was created
with.

Also added some tests for initialisation.

d2d94e203f Reverted isolation level values to backward compatible values 
This basically removes the READ UNCOMMITED level (that internally
PostgreSQL maps to READ COMMITED anyway) to keep the numeric values
compattible with old psycopg versions. For full details and discussion

88803695ac Normalize the encoding name at connection 
The encoding can be set by PGCLIENTENCODING, which may be an alternative
spelling. Bug reported by Peter Eisentraut.

At this point the idea of considering one of the random spellings such as
EUC_CN as somewhat "blessed" is debunked. So just store the cleaned-up
version of the encoding in the mapping table. Note that the cleaned-up
version was needed by the unicode adapter: this requirement has been
surpassed as the connection now contains a copy of the Python codec name
set whenever the client encoding is set.

Empty array can be returned untyped by postgres. To handle

99b3c72312 Some cleanup in mogrify 
- Raise an exception on incomplete placeholders.
- Minor speedups.
- Don't change the string in place (??!!) if the placeholder is not s
  and the value is null.

The latter point can be done because downstream we don't accept anything
different from s anyway (in the Bytes_Format function).

Notice that now the format string is constant whatever the arguments.
This means that executemany is still more inefficient than it should be
as mogrify may work only on the parameters. However this is an
implementation only worthwhile if we start supporting real parameters.

Let's talk about that for the next release.
