- It is now possible to use a custom array cast function by changing
the type caster for the 'anyarray' type. For instance, by calling
set_typecast('anyarray', lambda v, c: v) you can have arrays returned
as strings instead of lists. Note that in the pg module, you can also
call set_array(False) in order to return arrays as strings.
- The namedtuple classes used for the rows of query results are now cached
and reused internally, since creating namedtuples classes in Python is a
somewhat expensive operation. By default the cache has a size of 1024
entries, but this can be changed with the set_row_factory_size() function.
In certain cases this change can notably improve the performance.

Ok from OWNER, darcy.
Version 5.0.2 (2016-09-08)
--------------------------
- Fixed an infinite recursion problem in the DB wrapper class of the classic
module that could occur when the underlying connection could not be properly
opened (bug report by Justin Pryzby).
Version 5.0.1 (2016-08-18)
--------------------------
- The update() and delete() methods of the DB wrapper now use the OID instead
of the primary key if both are provided. This restores backward compatibility
with PyGreSQL 4.x and allows updating the primary key itself if an OID exists.
- The connect() function of the DB API 2.0 module now accepts additional keyword
parameters such as "application_name" which will be passed on to PostgreSQL.
- PyGreSQL now adapts some queries to be able to access older PostgreSQL 8.x
databases (as suggested on the mailing list by Andres Mejia). However, these
old versions of PostgreSQL are not officially supported and tested any more.
- Fixed an issue with Postgres types that have an OID >= 0x80000000 (reported
on the mailing list by Justin Pryzby).
- Allow extra values that are not used in the command in the parameter dict
passed to the query_formatted() method (as suggested by Justin Pryzby).
- Improved handling of empty arrays in the classic module.
- Unused classic connections were not properly garbage collected which could
cause memory leaks (reported by Justin Pryzby).
- Made C extension compatible with MSVC 9 again (this was needed to compile for
Python 2 on Windows).

The previous commit replaced the distfile with a new one with the same
name. In pkgsrc, we have rules for that; apply them.
|
|
Bumped PKGREVISION in case anyone already built the wrong one.
|
|
The biggest change here is Python 3.x compatibility. Other changes are too
numerous to list. See http://www.pygresql.org/ for all the changes.
|
|
Minor documentation and installation fixes.

- Set a better default for the user option "escaping-funcs".
- Force build to compile with no errors.
- New methods get_parameters() and set_parameters() in the classic interface
which can be used to get or set run-time parameters.
- New method truncate() in the classic interface that can be used to quickly
empty a table or a set of tables.
- Fix decimal point handling.
- Add option to return boolean values as bool objects.
- Add option to return money values as string.

either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE= 33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE= 33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.
Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.
Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.
Whitespace cleanups and other nits corrected, where necessary.

Mainly a bug fix. Also adds a preplacement for the functionality of
databases/py-pgnotify which no longer works with new versions of
PyGreSQL and PostgreSQL.

Changes since 4.0:
- Dropped support for Python below 2.5 and PostgreSQL below 8.3.
- Added support for Python up to 2.7 and PostgreSQL up to 9.2.
- Particularly, support PQescapeLiteral() and PQescapeIdentifier().
- The query method of the classic API now supports positional parameters.
This an effective way to pass arbitrary or unknown data without worrying
about SQL injection or syntax errors (contribution by Patrick TJ McPhee).
- The classic API now supports a method namedresult() in addition to
getresult() and dictresult(), which returns the rows of the result
as named tuples if these are supported (Python 2.6 or higher).
- The classic API has got the new methods begin(), commit(), rollback(),
savepoint() and release() for handling transactions.
- Both classic and DBAPI 2 connections can now be used as context
managers for encapsulating transactions.
- The execute() and executemany() methods now return the cursor object,
so you can now write statements like "for row in cursor.execute(...)"
(as suggested by Adam Frederick).
- Binary objects are now automatically escaped and unescaped.
- Bug in money quoting fixed. Amounts of $0.00 handled correctly.
- Proper handling of date and time objects as input.
- Proper handling of floats with 'nan' or 'inf' values as input.
- Fixed the set_decimal() function.
- All DatabaseError instances now have a sqlstate attribute.
- The getnotify() method can now also return payload strings (#15).
- Better support for notice processing with the new methods
set_notice_receiver() and get_notice_receiver()
(as suggested by Michael Filonenko, see #12 and #37).
- Open transactions are rolled back when pgdb connections are closed
(as suggested by Peter Harris, see #46).
- Connections and cursors can now be used with the "with" statement
(as suggested by Peter Harris, see #46).
- New method use_regtypes() that can be called to let getattnames()
return regular type names instead of the simplified classic types (#44).

Remove devel/py-ctypes (only needed by and supporting python24).
Remove PYTHON_VERSIONS_ACCEPTED and PYTHON_VERSIONS_INCOMPATIBLE
lines that just mirror defaults now.
Miscellaneous cleanup while editing all these files.

on some platforms that lacked shared library support in the past. The
list hasn't been maintained at all and the gain is very limited, so just
get rid of it.

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.
|
|
|
|
- assume that Python 2.4 and 2.5 are compatible and allow checking for
fallout.
- remove PYTHON_VERSIONS_COMPATIBLE that are obsoleted by the 2.3+
default. Modify the others to deal with the removals.
|
|
Remove PostgreSQL 8.0 as choice.
|
|
packages which have it active by default.

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.
