a24597d0e0 Fixed connection.poll() docstring

6e841a41e6 Dropped PSYCOPG_EXTENSIONS flag 
Building without extensions has been long broken and nobody really cares
about a pure-DBAPI implementation (which could be created using a wrapper
instead).

a31c1a1722 Allow get_transaction_status on closed connections 
It's a local operation and the libpq functions has a NULL guard.

3410fee8d1 Fixed leak of cancel key on connection.reset() 
Moving the final free into the destructor is not necessary but looks
appropriate.

cc605032f5 Added support for with statement for connection and cursor 
The implementation should be conform to the DBAPI, although the "with"
extension has not been released yet.

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.

b5de04d2ff Put back a distinct ISOLATION_LEVEL_READ_UNCOMMITTED value 2011-12-15 12:53:48 +00:00

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
see this thread:

dc94a3cb2d Check for connection closed before getting the isolation level 
Closes ticket #74

Also added test to check regressions in isolation_level,
set_isolation_level, set_session, autocommit.

d2b28abced Method set_transaction() renamed to set_session() 
In fact it doesn't change "the transaction", as there has to be no
transaction when invoked. The effect instead is to execute SET SESSION
CHARACTERISTICS.

869d48b6f0 Use the pqpath functions to get/set GUC parameters 
Functions conn_setup(), conn_get_isolation_level(), conn_set_transaction(),
conn_switch_isolation_level(), conn_set_client_encoding() reimplemented
using the pqpath funtitons.

Dropped analogous function in the connection, as it had to take the lock,
thus it was hard to build consistent pieces of functionality with it.

c2d1f1f2e6 Dropped isolation level from the connection object 
Don't issue a SET TRANSACTION ISOLATION LEVEL at every begin: use PG's
GUC default, eventually set by set_transaction.

Dropped the last query at connection, yay!

Method set_isolation_level() and property isolation_level refactored using
the new structures, keeping the previous semantic.

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.
